The Evolution of a Goblin to the Peak

The Greia's mana density was ten times lower than the Eidin. Eidin was the world where Souta, Alice, and Yuko arrived. The density of mana was too low compared to that world. The same could be said of the Prison World. He could understand why the Great Astley Empire wanted that world for themselves. Yet, the mana density of the Imperium was thirty times higher than that of Eidin.

Three hours had passed since they'd arrived in this world. Souta discovered monsters that he hadn't seen in the Imperium. He was a little bit surprised about it, but considering the parasitic essence eater, he quickly calmed down.

Ever since he left the Imperium, the only foreign thing that caught his attention was the parasitic essence eater. If he had time, he would secure one for himself and his team. The ability to boost the host's physical powers was great.

He recalled how those commanders have a B-rank power, yet when they use the parasitic essence eater, they gain the physical power that could rival an A-rank powerhouse, which was strengthened by their liquefied mana.

Aside from the boost in strength, the almost unlimited regeneration power was terrifying.

"I want to get a sample of their blood..." Isabella muttered while looking at the screen, which projected the monster's appearance.

Souta heard her words, so he looked at her and asked, "For potioneering, right?"

Isabella was surprised, as she didn't think that Souta would hear her. She looked down as she covered her mouth with her hands, but Souta kept looking at her. Accepting her defeat, she meekly nodded her head.

"Y-Yes... I want to know the properties of their blood. Since they are monsters that are immune to the toxins in the air, there's a possibility that their blood has immunity properties, which makes them immune to toxins. If that's possible, then I could somehow create a potion that will let us inhale the toxins without suffering for a short amount of time..." Isabella explained to him.

"I see... if it's not in their blood. Then, it must be some sort of organ that could filter the toxins, but if it's an ability, then it's going to be a problem." Souta nodded as he spoke to the people. "Capture one of those monsters and bring it inside the ship."

"Monster is not the only way... you could also send the properties of the toxins in the air, with enough study. I could just combine some ingredients to create a potion that could nullify it." Isabella said to him.

"Why didn't you say so sooner? Every ship had a record of the properties of the toxins. They knew it; that's why the toxins couldn't get inside the ships. Well, it is also a part of enchantment that the empire did in their ships." Souta paused for a moment before he added, "Well, just take the monster too. I already said this to you. You don't have to hold back.

Just simply ask me if you want something."

The ships of the empire, especially the Mother ships, were built to endure every kind of harsh environment in different worlds.

Cannons appeared on the surface of the ships. It fired dozens of white beams at the monsters in the vicinity. When they were sure that they had killed one monster, five people wearing protective equipment came out of the ship and took the monster with them.

Souta nodded with a satisfied look. Isabella should continue studying until she develops her talent to create those lost potions from ancient times. Anything that she wanted, he would provide it to her, even his own blood.

Oh? That's a great idea. Souta was a Blood Goblin, which was a super-rare variant of a goblin. He wanted to know what she would discover if she studied his blood.

The researchers in the Imperium studied countless species of monsters just to know how they could copy the high energy called best feram. The only fruitful result that came out were the monster potions. The recipe for the monster potion was lost, and no one knew how to recreate it. Numerous researchers wanted to know the data that the inventor of monster potions gathered from studying monsters.

Souta turned to his side and found that Isabella was already gone. She must have gone to check on the monster that they've captured.

He shrugged his shoulders and focused his attention on the screen. He couldn't help Isabella in her study, so he will leave her alone.

After one hour, Souta raised his hand as he signaled the people to stop the ships.

"Wait! I saw something. Zoom the projection in that part."

He pointed to the corner of the screen.

They zoomed in on the projection on the screen and saw a huge cave in the middle of nowhere. The cave was too far from them, so it was too small on the screen; that's why they didn't immediately notice it.

The two ships traveled several kilometers and finally arrived on top of the cave. The cave was huge, as its mouth has a radius of fifteen meters. Foreign monsters were going in and out of the cave, but after they arrived, the monsters stopped showing themselves. The two flying ships have scared them.

Souta observed the ships for a while before he said, "We're going down." He then turned around and left.

...

A loud sound echoed as a group of seven people landed on the ground. All of them were wearing protective equipment except for Souta.

Souta was using his energy to filter all the toxins that he inhaled. Only people who had great control over the energy in their bodies could do it. It's not something that everyone could do.

He wasn't afraid of these toxins in the air, as his body was that of a third evolution. It has a natural resistance against poisons, venom, or toxins, but he still thought that it was better to be safe. Although he thought about it, he still didn't wear the protective equipment.

Well, what he was doing was some sort of training too, training to control his energy. After evolving, his mana transformed into the best feram, and his control over this new energy wasn't as great as his control over his mana. That's why he needed some training to return to his previous energy control level.

"D-Do I really need to come?" Isabella asked. She was busy observing the corpse of the monster when Souta called her.

"Yeah, maybe we found something that suits your interest. I personally think that this place isn't just a simple monster den. I felt slight fluctuations of energy below it." Souta said to her.

"But what if it's just a powerful monster? I will not be able to help you..." Isabella said.

"Don't worry about that. If you're going to discover some unknown things, it's better to bring someone who knows a lot of things..." Souta smiled.

"But I don't know a lot of things..." Isabella tilted her head.

"Yes, but what I'm talking about is the knowledge of potioneering in your head." Souta pointed at his head.

"What's this got to do with potioneering?" Isabella asked with a confused look on her face.

"To create a potion, you had to know a lot of herbs and monsters. Not just that, sometimes a rare potion needed natural chemicals and high-grade ores as ingredients. A potion master knew about the characteristics of each ingredient and also knew how it would affect a person's body. Is it harmful or beneficial?

They also knew what would happen when they combined one ingredient with another..." Souta explained to her how great a potion master was. In fact, he was only describing the feats of Isabella in the game.

In the end, Isabella nodded at him. She couldn't even understand why he was telling her all of this. Is this really related to potioneering or not? Well, she decided to believe Souta, as he had no reason to lie to her or deceive her.

But... at the very least... she wanted to understand what he was saying.

Souta looked at Isabella and the five people that he brought. "Let's begin our search. Just follow me quietly." He said it with a serious expression.

Two of the five people were experts in other fields. They knew a lot of things about this world and could understand the languages of different worlds. Souta brought them with him as he knew that their knowledge was important.

The remaining three people were combat experts. They were experienced fighters who had the power of a D-rank adventurer in the Imperium.

The group advances forward as they step inside the dark cave. All of them were cautiously looking around their surroundings and watching everything in their field of vision, afraid of missing some important details.

They pressed a button on their protective equipment, and some parts of it emitted lights that solved their problem.

Souta didn't care about their lights. He had the [Night Vision] trait, so he could see clearly in any dark place.

"Let's see what's hidden here..."
