It Started With Devils & Artefacts

Marcus smiled at seeing Erina blushing on his lap. She might have become more assertive in private, but the girl was blushing a storm now when she was sitting on his lap while they were travelling to the Cretaceous Period.

"Do I need to sit on your lap while we travel?" the girl asked him while trying to think where to look. On the bridge, there were a bunch of girls who she could feel were judging her!

Thankfully, these are all bridge officers. None of his creations or maids or even his fiance came with them. After all, Marcus was like a small boy who rushed out when he got the news from the Assimilator in Cretaceous Earth.

"Why not? You are the one who is keeping me company." He teased her as his hands wrapped around her waist. She was feeling like a Princess in the claws of a big and very dangerous dragon.

'I wish I was not the only one.' 

Erina grimaced internally. She is chewing more than she can swallow.

There is a reason why Marcus Goldman has a harem. The man has a big appetite.

Not the appetite in the normal sense but in the female sense…

The beautiful chef girl recalled her last couple of days…

~~~~~~Couple Days Ago~~~~~~

Marcus awakened Erina's lust. The beauty was building it up for a while. Her mind would recall how often the Inventor takes his girls aside.

She could only imagine what he did to them. Eventually, all that builds up and needs to be released in some way.

Subsequently, she would channel it through her clothes, that was until he pinned her against a wall and had his way with her.

After that, he took her to the closest room and laid her on a couch. The massive Space Construct has a lot of space, not just for animals to be kept but for humans to live in as well.

Erina didn't have much time to think about how much space there was in the space station, as her eyes were on Marcus. She just lost her purity, and according to how it should continue, they should be resting, but the common rules don't apply to the man in front of her as he removed her suit device from her chest, and all of her clothes disappeared.

The nanites retreated to the triangle-shaped device, revealing her considerable breasts, lean stomach, wide hips and incredible legs.

"Did anyone ever tell you how incredible you look?" he whispered as his hands stroked through her body. That warm touch was giving her goosebumps.

"My interaction with males is very limited," Erina said with a hot voice as her gaze went to his body and then lowered to the hard cock, which was close to her special place.

"Good to know." As he replied to her words, he pushed her left leg aside and placed her right on his shoulder before pushing his rod right back into her special place.

"Ohhh~~~" 

Erina's moaned lewdly as she was feeling that thing spreading her wide.

With a strong smack, he was fully inside of her before starting to move in and out of her velvet cave.

"Nhhnnn~~" 

"Mhnnn~~~"

"Hnnn~~"

The cherry blonde beauty was gasping and moaning. From time to time, a pleasant current of pleasure would make her lose focus as she was feeling it.

Slowly, she started to lose whatever composure she had. Instead, the chef girl focused on the lewd act as she tried to be part of it, trying to move alogside it.

Before long, a lewd smile appeared on her face as her eyes gleamed with desire. The pleasure slowly took over the mind as her hands moved and stroked his chest, and a lewd and coy smile started to emerge.

"Oohh~ Yess~~"

Erina moaned hotly as the poke rattled her inside. Marcus slightly changed his angle as he proceeded to thrust into her sweet spot.

Her pussy started to leak love juices as she was swiftly approaching another climax.

"Ahnnn~~"

After a small climax, he moved her into a sitting position as he made the cherry blonde face him. The girl wrapped her hands around his neck as she moved in to kiss him while her legs wrapped around his waist.

She started to move on her own as her hips moved up and down in a rapid fashion.

The girl is a quick learner, and with improved genetics, she is ever faster at it.

Eventually, she was in sync with his moment, and she swiftly got that load she was working for.

"Hnnnn~~~ soo much is flowing into me~~~" 

Erina trembled as her feet were squeezing him as hard as she could. She could feel how he was pumping into her depths.

~~~

The Chef Girl's eyelashes trembled as she slowly opened her eyes and saw an unfamiliar ceiling. 

By this point, she was used to the dull grey of a space station or a warship, but this time, she saw warm blue colours that looked like clouds, and the bedsheets and pillow felt very fluffy.

For a second, she wondered where she was, and that was until she felt Marcus next to her as he was holding her close.

Her eyes widened for a second as she recalled a whirlwind of images, of very compromising positions.

'Now I done it…' 

Part of her always hoped that things would return to how they used to be…

Well, some of it? Part of it! Something! She had hope that she could return to her bubble. But, now…

She went and seduced the big bad wolf, well, calling him a simple wolf is being extremely humble.

But the point stands. Now, whether she wants to or not is fully in his clutches, figuratively and literally.

As she wondered about this, eventually, she somewhat calmed down and started to think about the positives.

"Hmm, you should sleep a little more." She heard his voice from the side.

"...I don't feel like sleeping anymore. Too much on my mind." Erina said while gazing at the ceiling.

"What's on your mind?" He asked her as his hands were holding her close.

"...This… this whole situation. What will happen now?" She asked with a concerned tone.

"By happening now, what do you mean?" He asked with a confused tone.

"...I mean… We did this…"

"Oh, that, well, you are mine, that is for sure." He hugged her even closer.

"...And what I am to you?" She asked, not knowing how to assess this situation. They would be a couple if he were a normal guy, but he is so far from normal that she has no idea where this relationship stands.

"My Erina. What else? I don't understand why you want to confuse this more than necessary." Now, he was confused.

"...What I mean, what am I to you? A g-girlfriend? A-A lover? I don't even know what to say…" along with all that stuttering, she was as confused as ever.

"Hmm, oh, that. You girls care about that stuff quite a bit." He commented with a realising look.

"Well, since that is the case, you will be my second girlfriend!" He declared her 'status'.

"..."

Part of Erina was relieved, but part of her was baffled. He has a girlfriend… a fiance.

"...Who is your girlfriend?" She asked curiously, who is this fearless girl who accepted that.

'Wait… I doubt she had a choice…' Erina realised that there are not that many beings who can deny what he wants…

"Latia Astaroth, she is the face of my Goldman Industries." 

The Chef Girl immediately put a name to a face. She recalled that blonde girl with an impressive burst.

"...Wait. Isn't she a devil?"

"Yep, that makes you a very special girl—a normal girl who was able to make me take you as my girlfriend. Let's just say your cooking was that good. I guess the stories about girls entering men's hearts through stomachs are not that far fetched." He joked while he got into a sitting position and moved her to sit on his lap while facing him.

"W-Wait, c-can we rest a while longer?" Erina realised that she would be forced to 'work'!

"But you said that you already rested~" He moved forward and placed his forehead on hers.

"T-That's a different t-t-thing! My body is tired, but my mind is not!" She complained while trying not to look into his eyes.

"That sounds like an excuse…" He teased the girl on his lap before returning to do things to her.

~~~~~~Back to Today~~~~~~

The cherry blonde recalled what had happened to her in the past couple of days.

She was feeling all sore and tired… she hoped that someone would help her, but all she got was his undivided attention.

Normally, she would be happy, but all of the things they do always lead to her passing out from passionate activities.

Oh, sure, she enjoys all of that, but she doesn't like what comes after waking up.

"We still have around 18 hours until we arrive at the Cretaceous Period. We should retreat to the living quarters." 

Erina tensed when she heard that. A tense and very desperate smile surfaced on her lips.

"S-Sure. But can we… just rest? Please? I am still new to all of these… girlfriend activities." She leaned forward and placed her hands on his cheeks, showing him a strained smile. 

"Sure, if this is what my Erina wants." He got up from the throne with the girl in his hands.

The Chef Girl realised that he was not even planning to let her walk on her own.

Panic started to rise in her gut.

"Umm…UMMMM…"

"Relax. All you are going to do today is do some basic girlfriend stuff—nothing major; it's not Graviton science." he clarified to her as he took her out from the bridge and towards the main lift.

"I don't even know what is this Graviton. But I am sore from everything you did to me the past couple of days!" She finally spoke what had been on her head for the past couple of hours! There is no way she will tell him that while in front of several crew members!

"And like I said, you will keep my company, make me some snacks, and we shall cuddle until we reach the Cretaceous Earth, " he said with an eye roll.

"Besides…"

His hands went to her legs as he started to send his energy into her body.

"My control over biological bodies improved considerably after studying millions of years of evolution~~~." 

Erina's eyes widened in horror as she sensed how all the soreness had evaporated.

"If I want to, I could be doing things to you for many, many years until your body would adapt. Think of it as an evolutionary stimulus to make you able to keep up with my sexual desires." He explained to her with a grin.

"...Y-You studied evolution just to make your girls able to keep up with you in bed?" She exclaimed in disbelief; this sounds like extreme misuse of the incredible data the Assimilator has collected!

"Not really. I already have evolution mastered to some extent as a power." He showed her his rings, taking off the Evolution one, which is on his right hand's ring finger.

"This is the ring of evolution. I'm pretty sure if a sophisticated civilisation were to study it, they could grasp evolution to some extent." He explained to her while showing her the ring from different sides.

"...Umm, not to sound rude, but this is far above my current level of magic." She said with a sweaty forehead.

"Maybe, but all I wanted to say was that the research was not in vain. One could say that I have streamlined it further than ever before." 

The ring floated back to his finger before his whole body glowed, as a dark green aura surrounded him for a second.

'In other words, he can abuse evolution even more.' 

The cherry blonde chef commented to herself as they arrived at the living quarters floor.

Marcus took her to his place, where the girl would be living from now on…

"Let's go get some snacks~ It will be great~."

Erina sighed. Not only would she cook for him, but she would also have to feed him while sitting on his lap.

Never in her life had she had to do such a thing…

But then she realised that none of the other girls could do this thing…

Not even Athena was cooking for Marcus!

It makes her stand in an extremely unique position.

'No, this is great!'

"Indeed. Tell me what you want… Marcus." The girl said his name with evident blush on her cheeks.

"Haha, you are getting there, Erina~." The Inventor smirked when he heard her finally say his name. He knew she talked about him while calling his name, but this was the first time she had said it right in his face.

Which is a step in the right direction, according to his books.

~~~~~~Next Day~~~~~~

A greenish-blue magic circle appeared as Confiscator blasted out from it and appeared above Cretaceous Earth. The exploration vessel faced the planet and proceeded to fly towards the Assimilator's core piece.

"The drydocks are in full swing." Erina swiftly noticed the huge amount of work happening in the docks.

"It appears security protocol has been initiated," Marcus replied as he raised his eyebrow at this development.

"Security protocol? You mean there is a possibility that there exists a possible enemy?" She asked with some worry.

"Not quite. It's more like contingency than anything. It's like walking into an uncharted forest. You do need some self-defence weapons, more than anything." He clarified to her as they arrived at Cretaceous Earth's Assimilator and proceeded to do the docking procedure.

As the magnetic hands grabbed the vessel and placed it in place, the gangplank lowered and attached to the exit, activating the escalator.

When Marcus and Erina left the spaceship, the girl noticed an array of bulky golden armoured men standing throughout the entire passageway. 

'Was the Assimilator converted into a military vessel on moment notice!?'

She understood how big it was, but transformed from research and collection to military structure in an instant!?

The cherry blonde gulped down as they swiftly walked the escalator-assisted bridge and ended up in the docks. They were picked up by one of the graviton shuttles, which would take them to the control room.

As they were travelling through the circular docks, the girl had the chance to observe what was happening there.

The amount of movement is foreign to the girl who spends a while in another Assimilator.

The Carboniferous one was almost like a ghost town compared to this one.

"Just how quickly was the entire army created?" She asked with wide eyes as she looked at how many machines were building the spaceships while, at the same time, knights were starting to gather and wait to embark on said ships.

The whole process was a borderline mechanic in her eyes!

"It's a rapid process. My faction has already experienced one war. We are learning and adapting from that experience.

To improve efficiency in soldier and warship creation, we are also looking for ways to enhance the quality of our knights and reduce the time needed to create them.

All of that is a balance game we are trying to find."

He explained as he looked at rows and rows of knights and mechs lining up in front of a Star Destroyer, which was being assembled at a rapid speed.

And it's not just one. Given how wide the drydock is, there are ten assembled at once, and since it's a tall station below this level, there are another three where other class warships are being built.

The shuttle arrived at the main lift, which would take them to the control centre. The pair didn't even notice how quickly they arrived as Marcus and Erina looked at knights gathering for their first interdimensional conflict.

The pair took the lift to the control centre. Marcus swiftly walked to his throne and sat down, pulling the embarrassed chef girl to his lap.

She felt extremely out of place…but… she couldn't argue with him. If he wanted her here, then there was nothing she could do about that.

"Sir." 

The Commander girl walked over to him and saluted before proceeding to explain what they had discovered.

With a hand motion, the planet's hologram appeared on the main hologram display in the command centre.

"The planet's core has an extra component which emits strange waves." The hologram shifted, showing the emission patterns.

"What does this component do?" Marcus asked as his attention was on the hologram.

"It emits waves which stimulate biological organisms. Preliminary observations indicate that it could potentially cause a shift in cell programming."

A DNA strand appeared, showing which cells are impacted.

"Hmm, now this is interesting…" Marcus looked at the strand while placing his chin on Erina's shoulder.

"...umm…what does this mean?" 

Erina asked him, as she had no idea what this meant.

"The one which is blinking is responsible for longevity. However, once you temper this cell, it impacts reproduction." He said that while his hands squeezed her waist.

"In other words, such component refined properly and consumed in some form could potentially give one eternal youth in exchange for the ability to reproduce," Marcus explained with a small frown.

"...Sounds like a potent way to control population." Erina ignored the squeeze and commented on what she heard.

"Not that simple. This is a potent killer of a civilisation. There is a chain reaction when you temper with just one cell." He used his mental interface to show the shockwave such change would cause.

"Reproductivity is extremely important not just for species survival, but it's linked with survival instincts.

If one has no desire to continue to survive, the person becomes living dead. Like a corpse." 

As Marcus was explaining, he realised that he had seen this before somewhere.

"It would seem quite a downside then. But is that it?" Erina asked with a somewhat dissapointed look. She thought they would find something useful.

But it was just extra composition in the planet's core.

"It's not just an effect on the body. It has an impact on the vegetation as well.

Such composition directly impacts wildlife. Over millions of years, the vegetation should have evolved in a unique way." Marcus reasoned as he realised that there is much more than just an impact on organic life.

"Yes, sir. We have discovered that ALL wildlife require the influence to sustain itself."

"Then!"

Erina realised what this meant.

"The moment an intelligent life starts harvesting this energy, the entire ecosystem will cease to work.

It would appear that this component is like a fuel." Marcus hummed as he placed his elbow on the armrest and his hand on his chin.

'It's an oddly specific thing, like a trope which will be used in future plot of this world.'

'There is a bunch of anime and manga with special energy or component that allows mechs to be used.' Marcus pondered internally.

"Do we have any idea for the potency of this energy as a fuel?" 

"M-Marcus, are you planning to harvest this energy!?" Erina exclaimed with worry, as she didn't want the planet to die.

"I don't need it as fuel. My faction is long past the point where we need finite energy to run things.

What I want to know is if such energy can be used to fuel a primitive faction, like how humans use fossil fuel." He clarified to his girl.

"Oh…"

"We can send a team to collect samples." As Erina realised he didn't want to milk the planet's core, the commander suggested to him.

"When do it."

Moments later, several of the outposts launched saucers to the active volcanoes to pick up samples.

As the saucers were busy, the inventor cuddled with his chef girl while examining the composition of the material. 

~~~

"Well, well, interesting."

Marcus stroked his chin while standing in the middle of the Control Centre and being surrounded by the holograms.

"It has stimulating qualities; we could expect an interesting development, " he commented with a smirk.

"Commander, I want you to put emphasis on active volcanoes. Especially when they erupt and pour the magma into the surface world."

"As you wish."

"The soil gets enriched by this substance, vegetation grows from it, and it gets consumed by herbivores, and carnivores eat those.

There is an entire ecosystem around this. It's only a matter of time until sapient species appear." 

He clarified what he was aiming at.

"Wait… you are saying we will get sapient dinosaurs!?" Erina exclaimed with shock.

"Yes, the smarter one will become smarter. The issue is that there are not that many alternatives. Most of the smart ones are predator hunters."

He said while returning to look at the samples he had.

"Begin preparations for time slip. We can watch this from outside the time flow." 

"Beginning the preparations!" 

The crew scrambled to start the preparation.

As they were doing that, Marcus dismissed the hologram windows and returned to his throne.

"It will take some time. Why don't you get some desserts? I feel like celebrating, " the inventor said while looking to his side, where the girl had been standing the whole time.

"...Sure…"

A couple hours later, the pair returned and saw that time was flowing much faster.

"Cretaceous is quite a long period, from 145 million to 65 million years. There is quite a bit of time to pass." He said that while pulling Erina back to his lap and watching how the continents move towards familiar locations.

"...sir…" 

The commander walked over to his location.

"There has been a development."

"Oh? Slow down the time slip." He ordered the crew before looking at the commander.

"Tell me."

"The raptors started to become smarter around the areas where volcanoes are. Their hunting patterns are becoming sophisticated, and their mating practices have improved. They are becoming similar to modern wolves."

"Hoh, so they realised that incest is bad. Hmm, continue to observe. I want to focus on them."

"Yes, sir." The Commander saluted before they continued to watch the raptors.

Marcus quickly noticed that the raptors had blue skin and small horns.

…

…

…

"Amazing… they are getting smarter right in front of us!" Erina watched the whole thing with bated breath. It was like watching evolution take its course and these animals slowly becoming self-aware.

"They are becoming similar to us."

She said with wide eyes. Their posture changed. They straightened up, and they started to use tools more than their claws, which caused a fundamental shift in their physiology.

"Oh, it's happening." Marcus softly said that as he looked at this with a gleam in his eyes.

"...Fire…" Erina realised what he meant.

They 'unlocked' the first element, and from here, the first sapient civilisation was born.

These raptors were nomads at first, and Marcus watched it with glee.

"Let's go. They are leaving their location of origin." The inventor grabbed the girl, and they rushed to board a train that would take them to the closest outpost to the raptor location.

"Can't you just move the Assimilator? We don't need to travel there, don't we?" Erina realised that they would take that scary train…

"It's a delicate situation now. Moving Assimilator could make them see the night sky differently…"

As he said that, he stopped in his tracks and put her down.

"Hmm, I got an idea." 

He turned around and returned to the Control Room.

"We are going to guide them. I want an obelisk with the intent behind it. Aurora, design me a couple of templates for it. Make sure it's made from metal not found naturally."

"Wait! You are going to interfere in their development as a civilisation?" Erina caught up to him and heard what he ordered.

"Precisely." 

He nodded at her before explaining why.

"They are carnivores, not omnivores like us. They won't just settle down and start growing a farm." 

The chef girl quickly understood what he meant.

"We never studied a civilisation of carnivores species before." Marcus pointed out to her.

"Yes. Now that you mentioned." She nodded at him before thinking about how these sapient raptors could create a community—a first proper village, instead of just wandering around.

"The animal husbandry comes to mind," Erina said to him as she pondered on this.

"Taming animals could give an array of perks and possibly allow them to settle down in a location." She said to him.

"Indeed, my thoughts exactly. Do that." He nodded back at her before looking at the Commander.

"Create an obelisk with that intent." 

"Understood. We shall begin with designing of that." The Commander girl saluted before replying.

"Good. For now, we shall visit the caves they left before and move the Assimilator so that we can descend with minimal effort."

"At once!" The commander turned around and issued orders.

As the Core of the Assimilator moved to the location, Marcus looked at his girl.

"How does it feel like to be part of a new civilisation?" He asked with a curious tone.

"...It has not settled down yet," Erina replied with a strained smile.

"I know. It's the same for me as well. That is why we will visit the caves where they lived." He smiled while saying that.

She looked surprised for a second.

"I thought you digested all of that already. I mean, you are so confident." The girl commented about his behaviour.

"Just because I don't show it on my face doesn't mean my heart is racing for new discovery."

Marcus pulled her into his hands and made her place her hand on his left chest.

"Can you feel that?" He asked with a teasing grin. The inventor is enjoying every moment of his darling chef girl. Since he knows she will eventually develop a thick 'skin' from all this teasing.

So, he needs to tease as much as possible.

"I-I see." She tried to move away, but Marcus pulled her closer and was ready to kiss.

"No need to rush~."

"Ummm!!! Can we do… naughty stuff in the privacy of our quarters?" The girl suggested as she looked away.

"Our? I like the sound of that." 

Marcus pulled back. He realised that his lovely girl already saw herself as part of his household. This made him quite happy, considering he had, by all means and purposes, strong-armed her into his services.

The pair waited for the Assimilator's core to move into the position before walking to the hangar.

"Do prepare your suit device. While the Cretaceous is not Carboniferous, there is over 11% more oxygen, and it's far too humid for humans."

As he explained to her, he walked to the edge of the hangar and looked down at the planet below.

"I know." Erina has already done her research; unlike before, she is not clueless.

"Are you planning to fly like this?"

"Yes. You can take a shuttle if you want." With a thought, his clothes changed, and he was fully encased in black armour.

"No. I can travel with you like this." Her clothes changed as well, as she stood next to him.

"Nice. The crew will follow after us." Marcus was pleased that Erina was no longer a scaredy-cat. Well, it takes a while to get used to flying and denying naturally born instincts, but the suit's power mitigates those fears.

So someone who was a simple girl can become an adrenaline junkie. Not to mention, the cherry blonde is becoming a powerful time law user.

"Are they going to research the caves?" Erina enquired as they were getting ready to jump.

"Yep, we are going to research into these primitive society structures." 

"Then let's go."

~~~

The pair landed on the gravel and looked around. They were using hologram scanners to scan their surroundings and find points of interest.

Their eyes ended up on rocks, a burned-out campfire and leather-like clothes.

"I just realised that they use leather for clothes instead of fur," Erina said with a perplexed look.

When one expects cavemen, they expect clothes made from furs, but these primitive sapient raptors have leather clothes made from Hadrosorids and ceratopsids.

"Yes, well, proper large-furred animals will appear in the next 20 to 30 million years. That is considering this world has the same extinction events." Marcus said while pointing his hand around the campfire. Luckily enough, he found some blood samples.

"True. But isn't this Earth closely related to ours? I mean, when you decided to send Assimilator to this place, should it have similar coordinates?"

"Indeed. But the difference percentage was extremely small… but it was enough to make a sapient raptor civilisation exist." Marcus replied as he crouched down and scanned the blood.

"Aurora rebuild the DNA."

[Rebuilding…]

What he saw was the blood of a Torosaurus, one of the Ceratopsids—the horned dinosaur.

"Well, this is a bummer. I want to find some DNA from those sapient dinosaurs." He sighed in disappointment before hearing Erina exclaim from inside the cave.

"Marcus! Look at this!" 

Her voice was quite excited, so he quickly appeared in front of the cave and walked inside.

His eyes widened as he saw paintings on the walls.

"Isn't this like those cave paintings in France? Thousands of years old?" she gushed as she looked at the wall depictions of dinosaurs from that era.

"The colours are quite soft or even easy on these, but that one…" She pointed at the side where a primitive painting of something akin to a T-rex is painted in red, like danger…

"They used blood as paint to showcase their fear of that big one." The girl theorised what she was looking for.

"Well, they are carnivores. I can only guess they are competitive because of their meat-only diet." Marcus reasoned as well. Considering he is not someone who studied societal structure.

"True, meat as diet could do that."
