Became A Necromancer In a Zombie World

"Haah, haah, ... Mister♥"

With a deep breath from the afterglow of climax, Yoo Ha-yeon, nestled in my arms, caressed my chest with her dreamy eyes.

I was lying on the bed, embracing Yoo Ha-yeon with one arm.

While fondling her breast with the arm that held her, I stared into space.

'... Pregnancy, and enhancement?'

Even as I was inside Yoo Ha-yeon, a message appeared.

It was said that my bodily fluids had been absorbed above a certain level, granting her the undead trait.

And then, this message popped up after I had ejaculated into her womb.

'So, can I choose whether she gets pregnant?'

I couldn't help but laugh.

That means I can fill her womb without worry, no need for condoms.

Or it could mean I could get her pregnant with my child whenever I want.

And there's something even more crucial.

[Enhancement]

'Enhancement, huh...'

It probably means what it says on the tin.

I'm not sure what exactly gets enhanced, but the message's implication.

And the message about bestowing the undead trait through my bodily fluids.

The undead trait definitely includes [Pain Reduction].

So, does that mean I can give special abilities to women I have sex with?

'I guess I have to try the enhancement option without much thought.'

Pregnancy is out of the question right now, and doing nothing would be a waste.

Maybe it's a message that only appears after the first internal ejaculation.

Without hesitation, I pressed the [Enhance] button.

━Ding.

[You have chosen to enhance 'Yoo Ha-yeon'.]

['Yoo Ha-yeon' has absorbed your bodily fluids and become your servant.]

[First servant bonus. The probability of the roulette increases.]

[Proceeding with the trait roulette.]

A flurry of messages flashed before my eyes, disappearing and reappearing, until the final message was displayed.

[Enhancement completed. The trait 'Physical Enhancement (S)' has manifested in servant 'Yoo Ha-yeon'.]

[The 'Servant Menu' has been activated due to owning a servant.]

'Servant Menu?'

It seems like a new status window has opened, similar to the previously locked skill window.

I immediately activated the servant menu.

A screen popped up with Yoo Ha-yeon's name alone in an otherwise empty field.

Clicking on her name brought up another screen filled with various details about her.

[Name: Yoo Ha-yeon

Trait: Physical Enhancement (S)

Servant Progress: 5%

Affection towards owner Lee Seo-ho: 70%

Current Status: Sleeping, Dependent, Hungry, Tired]

It listed Yoo Ha-yeon's traits and various other stats.

'My affection rating is 70%... That's higher than I expected.'

Though I'm not sure what 70% really means without a standard.

But it's over 50%.

Considering today was the first time I saw her face, this is quite high.

Especially since I kind of coerced her into it.

Yet, it seems I've managed to earn some affection from Yoo Ha-yeon.

And among the various statuses listed, 'sleeping' stood out.

Looking at Yoo Ha-yeon, who was nestled against my chest, it was clear she was asleep.

From the moment I first saw her, her face was etched with anxiety and despair, and even during sex, her expressions were of pain or pleasure.

Seeing her peaceful sleeping face now, I realized how beautiful Yoo Ha-yeon truly was.

'...Should I really make her an idol?'

Her face was prettier than any center idol featured in various media.

Plus, her breasts seemed to be at least a G-cup.

'To think I had sex with such a girl.'

And it was my first experience.

Moreover, she was a virgin, and I didn't use protection, ejaculating directly into her womb.

Afterward, she seemed to lose consciousness and fell asleep in my arms.

Her warm body temperature, her soft skin.

And she smelled nice.

I moved my hand, which was resting on her breast, freely exploring.

I squeezed, felt the elasticity, and played with her nipples between my index finger and thumb.

"...Mmm, haah..."

Her face flushed in response, even in sleep.

"Really sensitive nipples, huh."

Even though she was fast asleep, her whimpers from the nipple play were cute.

'...Maybe I should sleep too.'

I wanted to go another round or two, but I'm not that much of a jerk.

She's a girl who's mentally and physically exhausted, taking in my cock for survival and now sleeping from exhaustion.

Let her rest for now.

Thus, my first experience ended with various benefits, falling asleep happily in Yoo Ha-yeon's sweet embrace.

. . .

Morning came when I opened my eyes.

"Ah, ...you're awake?"

A good morning greeting from a pair of large breasts and a pretty face beyond them.

And the soft sensation on my head.

Yoo Ha-yeon, who had changed clothes, gently laid me on her thighs, stroking my head.

'This is the best.'

For some, this world might have turned into hell, but for me, this moment was the happiest in my entire life.

"Sorry... I thought about preparing breakfast, but I couldn't touch the food without your permission..."

As I sat up, she apologized with a worried look.

"No, it's fine. I brought the food for you to eat anyway."

"Is that so?"

Relieved by my words, she smiled faintly.

Looking around, the place seemed cleaner than yesterday.

And she wanted my permission even though she must be hungry.

'Good attitude.'

Maybe she's anxious that I might just have sex with her and then leave.

Stories of 'hit and run' were common even before the zombie apocalypse.

From a woman's perspective who has accepted a man's cock, there's nothing left to do but try not to be abandoned.

Of course, I have no intention of abandoning her.

Yoo Ha-yeon has endless value both as a woman and as a slave.

Afterward, I selected some of the food I brought to prepare breakfast.

It was simple and modest for a meal.

"Is it really okay to eat this much?"

"It's fine. Don't hold back, eat."

For Yoo Ha-yeon, who probably hadn't eaten her fill since the zombie outbreak, even this would be a feast.

"But with this amount, we could last three more days..."

"I told you not to hold back. There are plenty of ways to get more food. And this is my way of showing trust."

"Trust?"

"We're going to live together from now on, so I can share my food freely."

Yoo Ha-yeon's eyes welled up with emotion at my response.

"Mister..."

A warm word of being together for someone who feared abandonment.

And sharing precious food as proof.

Tears streamed down Yoo Ha-yeon's cheeks.

"Don't cry! Why cry when it's good news!"

"But... I'm just so grateful..."

She wiped her tears with trembling hands and bowed her head.

"I... I feel so worthless, receiving something like this..."

Perhaps she thought of herself as valueless, having done nothing but stay hidden at home.

After all, getting food in this apocalypse is life-threatening.

I intended to give her a carrot after all the sticks, but the effect was surprisingly significant.

━Ding.

[Yoo Ha-yeon's affection has increased.]

Seeing the message, her affection seemed to have risen significantly.

"You're not worthless."

There's always a way to use anything or anyone.

I didn't voice my inner thoughts but gently stroked Yoo Ha-yeon's head.

She smiled shyly, tears still in her eyes.

'Now, shall we proceed with the plan?'

After breakfast, I decided to carry out my original purpose of finding survivors.

That was the enhancement of the crystal.

But first, some preparations were necessary.

After all, while I might be immune to zombies, Yoo Ha-yeon wasn't.

'There was nothing specific about servant traits.'

If there had been, it would have mentioned not being hostile to the undead like me.

Thus, necessary preparations.

This involved the zombies at the department store where Yoo Ha-yeon would live.

It was too cumbersome for her to travel between her apartment and the department store.

So, I planned for Yoo Ha-yeon to stay at the department store.

'I didn't originally plan to let just anyone in.'

But Yoo Ha-yeon was alone and my first slave.

So, I decided to clear out the zombies from the department store's parking lot entrance to the bedding section.

"I'll be back."

"...Mister."

I vaguely explained to Yoo Ha-yeon that I was going to look for food.

As I was about to leave, Yoo Ha-yeon grabbed the end of my sleeve with a worried look.

It seemed trust hadn't fully built yet.

She seemed mostly worried about being abandoned.

"It's okay. Zombies aren't much of a threat to me. I'll definitely come back, so rest easy."

"When will you be back?"

"Maybe a day or two."

I planned to return in three days.

Yoo Ha-yeon was indeed mine, but she still needed more training.

Training to understand the fear of losing me.

Perhaps the anxiety of potential abandonment would increase her dependency on me.

A slave needs such dependency.

That way, she won't betray me if something happens later.

So, I intended to return later than planned.

"Please be careful...!"

Yoo Ha-yeon saw me off with worried eyes as I left the room.

'Now, let's get to clearing.'

. . .

What I had to do wasn't overly complicated.

I could organize the living environment at the department store after Yoo Ha-yeon arrived.

The important thing was ensuring Yoo Ha-yeon could reach the department store without being blocked by zombies.

And once there, the path from the parking lot to the third floor was crucial.

If Yoo Ha-yeon got bitten by a zombie, it would be disastrous.

"Phew, this should do it."

Moving zombies wasn't particularly difficult, just labor-intensive.

Since we would drive to the parking lot, the main area to clear was from the third floor of the parking lot to the entire third floor of the department store.

This S Department Store, the largest in the area, had a separate parking building.

Each floor of the parking building connected to the department store via bridges.

I left the zombies on other floors for security but focused on clearing the third floor.

"Hmm... Will she like this food?"

After clearing, I packed suitable food in my backpack.

After all, she was my first experience partner and my precious first slave, so I wanted to bring her something tasty.

Though, given the need for preservation, the options were limited.

Having finished all preparations, I checked the servant menu before leaving.

[Name: Yoo Ha-yeon

Trait: Physical Enhancement (S)

Servant Progress: 5%

Affection towards owner Lee Seo-ho: 72%

Current Status: Dependent, Anxious, Despair, Delusion]

'...It's serious.'

Intentionally or not, if it weren't for the zombie situation, she'd need psychiatric treatment immediately.

But what can you do? After giving her a carrot, it's time for the stick to continue her training.

Especially since I was now including her in my living space at the department store.

The training had to be thorough.

After clearing the department store, I leisurely walked back to Yoo Ha-yeon's one-room apartment.

━Knock, knock.

I knocked in the pre-arranged pattern, and I heard hurried footsteps from inside.

Bang!

"...Mister!!"

As soon as the door opened, Yoo Ha-yeon rushed into my arms.

"Why did you come so late! You said you'd be back in two days! I was worried!"

She cried into my chest.

"Sorry, I had some things to handle, and it took longer."

"I thought... you might be dead..."

It seemed she was more worried about my death than being abandoned.

'Her trust in me seems higher than I thought.'

After all, imagining abandonment in such a desperate situation must be unbearable.

My purpose of making her feel the anxiety of my absence was achieved.

"Ha-yeon."

"...Yes?"

After calming down in my arms, Yoo Ha-yeon looked up at me.

Training is good, but now it's time for important work.

"I've been thinking, how about moving to a new place?"

"What... do you mean?"

"The place I found before, let's go there together."

Yoo Ha-yeon's eyes widened at my suggestion.

"Me... go there?"

As expected, she was scared to leave this room and move to another place.

"Don't worry. I've prepared a safe way to get there."

"..."

Yoo Ha-yeon couldn't give a definitive answer.

She seemed hesitant.

Leaving this place might increase her chances of death.

"Can't we just stay here? I think we can manage well here..."

And she proposed an opposing idea.

'This won't do.'

Clearly, her training was not complete.

A slave who opposes my suggestions is unnecessary. And one who doesn't trust me when I say it's safe is also unnecessary.

I need to teach her what happens to such a slave.

"Okay, then there's no choice."

I nodded, pulling Yoo Ha-yeon away from my embrace by her shoulders.

Seeing me agree, Yoo Ha-yeon smiled with relief, but...

"I'll have to leave you behind."

Her smile turned to despair at my next words.

"Mister...! You're joking, right? Please don't do that! If you leave me..."

"But you don't trust me, right? Even though I assured you it's safe."

"But still...!"

"Sure, even if it's safe, there could be accidents."

I nodded as if understanding her fear.

"So, this is where we part. I can't trust someone who doesn't trust me."

I had told her before about betrayal.

She knew how much I valued trust.

That was the first condition before our physical relationship.

She had promised to follow my words unconditionally.

Realizing this, Yoo Ha-yeon's face turned pale, and she clung to me with trembling eyes.

"I'm sorry, Mister! I was wrong! I'll do whatever you say! Please, don't leave me...!"

"Will you do as I say then?"

"Yes...! I'll do anything you command! I'll do everything...!"

Crying and pleading, Yoo Ha-yeon begged me not to abandon her.

Good, she now understands that my suggestions are commands, not suggestions.

And that disobeying them leads to abandonment.

A well-behaved child deserves praise.

I smiled, stroking her crying head.

"Don't cry. If you follow my words, I'll protect you. Don't worry."

"Yes... I'll follow, I'll follow everything you say...!"

"Good. Let's get ready then. We're moving to a new home."

At my words, Yoo Ha-yeon nodded through her tears.

Now, let's take this cute slave to my sweet home.
