I Spread my Genes to Level Up in the Apocalypse

Ray slashed with his tomahawk, casually crushing the head of one of the level-one undead with precision.

"Not bad." He felt the mutation energy in his body and nodded with a satisfied expression.

Previously, since he advanced in Necromancer and Lightning Arts skills, his mutation energy had decreased to 123.

Now, it has increased by more than 250, already reaching very close to 400 mutation energy.

"Status."

Mutation Energy: 387

"Are these all the undead in this area?" Ray asked lightly.

"Yeah," Seraphine nodded.

"We usually clean up this area regularly around the Awakener Association, so this is all the undead. If you want to hunt, you'll need to go further."

Ray looked into the distance and nodded. "I see."

"King still hasn't arrived, huh?" Ray frowned slightly.

"Yeah, he goes far away and takes a long time to come back. Damn it, how many girls are weeping because of him on those trips?" Seraphine gritted her teeth. "Even children are not spared." Her tone was extremely hoarse with bloodshot eyes.

Ray remained expressionless.

Although he hadn't yet done that with Seraphine yet, he had grown much closer to her, especially since he was living in her apartment.

He had to admit he was very satisfied with Seraphine's apartment.

The bed was exceptionally comfortable, literally sinking him, and it remained sturdy even with regular use during exercises with Gina and Melissa.

By the way, there were dark circles beneath Seraphine's eyes, revealing deep tiredness. Ray could guess what she was doing at night; after all, they were quite loud...

"I should get some proper sleep tonight," Seraphine muttered to herself. He was right; Seraphine couldn't sleep properly due to the loud moans at night.

Even with those noise-cancellation pods, curiosity got the better of her.

The sounds she heard were enough to make her conclude that Ray was a true monster.

The moans were continuous all night long without a single rest, the voice differed but the flesh slapping sound never stopped.

It was as if he never rested, always the first to wake up early in the morning, full of energy, while she suffered.

Seraphine was often left speechless by this, though she had gradually adapted to his quirks.

Bang!

A gunshot rang out as three undead heads exploded from a sniper bullet.

"You guys, why are you being so distracted?" Gina called out from afar.

Ray wasn't particularly interested in these few undead, but suddenly, he thought of something.

"Don't shoot them," Ray shouted back, then casually walked towards one of the undead. He crushed its ugly hand and feet, completely immobilising it.

He took out a red pill from his pocket—he had received it when Vanessa used her power against the undead, but he had never experimented on it.

"What is that, Ray?" Seraphine asked curiously.

"I don't know." Ray shook his head, examining the red pill. His analyzer skill could only identify its name:

[Berserk Pill]

The details were unknown to him. Red was always used to indicate danger.

While the Green Pill was known to provide nutrients and minerals to the body, the red pill reeked of potential danger even though the name could provide context but he still needed to experiment.

Ray casually fed the red pill to the immobilised undead, stuffing it into its mouth without mercy.

"Would this be considered cannibalism?" The thought crossed his mind almost immediately.

After all, this red pill was made from Vanessa's power, turning the undead into this red pill.

"Why am I always thinking of weird things?" Ray shook his head, focusing on the undead and carefully observing every minute change in its body.

Shortly after, just a minute of waiting, Ray noticed that its red skin was slowly glowing, and veins began to protrude all over its deformed body.

Then it started to roar loudly, reaching his ears.

An undead's sound was usually very subtle unless Ray strained his ears in deep quiet; only then could he hear it. This was true for normal undead.

Then, before his eyes, the undead began to go berserk, thrashing its limbs and trying to move toward Ray with madness.

Ordinary undead were completely emotionless, but this one was showing rage toward him.

Ray stopped the furious undead with just a finger, firmly immobilising it. However, his expression shifted to surprise.

"Its strength is at least double than before."

As he watched in astonishment, after ten minutes its body slowly started to break down, turning into ashes.

"Hmm, I need more experiments," Ray said, narrowing his eyes at the ashes.

If it was truly what Ray thought it was, it could be useful to him.

Soon, Ray casually captured a few of the scattered normal undead and began feeding them the red pill after immobilising them.

The effect was exactly the same as before: their strength increased, and they died within Ten minutes.

Ray had Vanessa make more of these red pills for experimentation, but he had never bothered to test them before; it had slipped his mind, especially since he was focused on spreading his genes diligently.

"Hmm?" Ray glanced at the ashes and then turned back. He wanted to test the pill on a Level One undead, but unfortunately, all of them had already been cleaned up.

"It's essentially a berserk pill," he mused. "I wonder if the effect would be the same on a stronger being and whether it would kill them every time."

He walked back into the base, with Seraphine remaining silent throughout the process, carefully observing all of Ray's actions.

Once everyone had returned to the base, Seraphine was the first to speak to Ray.

"What kind of pill is this?"

"It should be a berserk pill, from what I know, as you can see."

"Berserk pill?"

"Yeah," Ray casually stated. "You stay here; I will go to my bedroom."

"Okay." Seraphine obediently left.

Ray returned to his room and uttered the awkward word he regretted using: "Wakey."

Instantly, an eerie darkness spread, and through it, a Level One undead dog appeared in front of him. Ray casually fed the red pill to it.

"Hmm?"
