I Spread my Genes to Level Up in the Apocalypse

Ray felt the mutation energy rapidly draining from his body and frowned slightly.

"Is the consumption really this terrifying?" he muttered.

Despite having slaughtered undead like grass along the way, and with his mutation energy close to crossing the thousand mark, the condition was not optimal.

"When I have enough mental energy," Ray's eyes flashed with contemplation.

[Mutation energy: 923]

---

This was already a sizable amount of mutation energy, but there wasn't even an advancement for the Body-Strengthening skill yet.

Ray hesitated, weighing his two options: patiently waiting to upgrade his Body-Strengthening skill or advancing other skills.

Crooooaak!

As Ray was distracted, he suddenly heard a terrifying sound wave. His ears started to bleed on the spot.

"Close your ears," Ray hurriedly instructed the two women, but his efforts were futile. Even while covering their ears, their eardrums were still damaged.

He frowned, he was absolutely fine with his physique so high not many things could damage him, but the two women were in an extremely miserable condition.

"Go to a house and take cover first," Ray said, taking them by their soft waists and instantly reaching a nearby building to shield them.

Luckily, the vibrations were a little less intense inside the building.

"Stay here," Ray instructed them softly.

He then walked out with a dangerous look on his face, taking out his modified Dragunov SVD.

"Who is doing this?" Ray focused with closed eyes.

It's said that when one sense is blocked, another becomes stronger, just like how a blind person has better hearing than a sighted person.

"Up?" Ray muttered, eyes filled with confusion as he looked skyward.

Ray's pupils widened to their limits. "What is that?"

In the sky, a huge black bird more than the size of a normal man soared.

Its claws were sharp and strong.

Eveytime it flapped its giant wings, which were particularly majestic, a small gust of wind formed, almost creating a tornado.

Its blood-red eyes scanned the area, but the most peculiar thing was the unknown patterns imprinted on its black feathers.

The most terrifying detail was the "2" marked on its head.

"A Level 2 undead bird?" Ray's heart stirred. He had never seen an undead bird before, let alone one at Level 2.

At that moment, gunshots rang out, followed by the roar of missiles.

Unfortunately, the bird was too fast, effortlessly evading all the attacks.

"Attack without mercy!" A woman's voice boomed from a microphone, and the assault on the undead bird intensified.

Homing missiles, tank shells, and sniper fire converged on the creature in a relentless barrage.

"Interesting," Ray muttered, eyes flashing with interest.

He had no intention of attacking the bird with the sniper.

With only a barely modified sniper, he couldn't compete with tanks and missiles.

Probably because of this humanity was losing just a level two undead being already proved all the tricks of the modern era almost effective.

"Is it the military?" he wondered aloud.

Ray moved lightly, his figure becoming a blur as he climbed one of the tallest buildings in the area.

His strength was already inhumane, enabling him to scale the structure like Spider-Man.

He clawed the wall with one hand and one leg, maintaining his balance effortlessly.

From his bird's eye viewpoint, Ray finally spotted all the tanks and weapons stationed outside the city, their formations scattered and chaotic.

"What a mess," Ray muttered with disappointment, shaking his head.

Tanks were haphazardly positioned, and soldiers frantically moved between positions, trying to maintain some semblance of order.

The noise of the battlefield reached him in a cacophony of shouts, explosions, and the screeching of the undead bird.

Although they all attacked together, the speed of the bird was terrifying.

The snipers couldn't penetrate its strong feathers and could be said to be completely useless.

The missiles and artillery fired were directly dodged by the undead bird.

Ray squinted his eyes. This bird was definitely smart; its intelligence might even be comparable to an adolescent human.

"Do they gain more intelligence the higher their level reaches?"

This conjecture felt true to Ray.

"I wonder if it reaches a higher level like Level 4 or 5, will it already have a higher intelligence than us humans?"

Ray shook his head and used his analyzer skill to analyse this Level 2 undead bird.

Humanity was struggling with even this Level 2 bird, as all these tanks and guns proved ineffective.

If, in this time period, a Level 3 undead creature arrives, it could probably slaughter us all.

The jump in an undead's strength was not to be underestimated.

A normal undead had the average power of the original person, but when they became Level 1, even killing them with knives would be hard.

Only inhuman strength could easily slaughter them.

Now, a Level 2 undead could already take care of the military. This undead bird seemed to be playing with the fully armed military as if they were toys.

Of course, the type of undead would differ.

What if an elephant became undead?

Ray shuddered at the possibility.

[Undead Raven

- Level: 2 (Limit 4)

- Bloodline: Archaeopteryx (diluted 1/1000th)

- Abilities: Sonic Wave, Sonic Speed, Wind Manipulation, Flight, Spirit Manipulation (locked)

- Description: The mutation has affected the raven and also stimulated the hidden bloodline of Archaeopteryx, the first of all birds, inside the raven.]

"Oh, the first of all birds?"

Ray never thought he would hear such a thing before.

"Is there a first for us humans too? But if there is, it will probably be a gorilla." His expression turned strange.

"Maybe some people also have a Gorilla bloodline?"

Ray's expression grew even weirder at the thought of this.

But anyway, he wanted to act now.

It wasn't because the military was in trouble, but because this little bird might give him a lot of mutation energy.

A level one undead gave him 50, while normal undead only gave him 1. If the ratio was 1:50, then…

Ray's eyes almost took on the shape of dollar signs.

He didn't wait for too long.

As soon as the raven landed on the ground, he immediately shot towards it at full speed, almost as if he were flying through the air.
