I Spread my Genes to Level Up in the Apocalypse

The Level Two undead cat had a dense network of patterns across its skin, with the number "2" imprinted on its head. Its three tails flowed freely, but its size was no larger than that of an average cat.

Zhh!

The Lightning Spear surged through the air, striking the cat squarely in its body without mercy.

"Hmm?" Ray frowned. The cat remained almost perfectly unharmed, not a scratch on it. However, at the end of its three tails, a blue flame ignited, blazing with fury.

The mother, terrified by the sight, ran away as fast as she could without looking back.

The Level Two undead cat turned toward Ray with a ferocious expression.

Ray could see the scene clearly: just as his Lightning Spear was about to land, the Level Two undead cat's body absorbed the impact without taking any visible damage.

The flames erupted from the three tails, completely obliterating the Lightning Spear before retreating back to their original position.

"Hellfire manipulation?" Ray squinted his eyes as he recalled the abilities this cat possessed. It was even stronger than the Raven, despite both being at Level Two. However, their bloodlines were a different story.

The Raven's bloodline was extremely diluted, only 1 in 1000, but the cat had a bloodline purity of 1 in 100.

Although their bloodlines weren't the same, Ray could easily tell which was stronger at a glance, given the cat's many abilities and the pressure it exuded from its mere presence was much stronger than Raven's.

"Wakey," Ray muttered while floating in the air, a hint of embarrassment colouring his cheeks.

An eerie darkness enveloped the entire scene, and a Level Two Raven and Argos slowly emerged, shrouded in the same darkness.

The Raven stood tall and proud, almost reaching Ray's height, exuding undeniable majesty. On its back, Argos was seated, holding two massive greatswords in both hands with an expressionless face.

"He really came with swords?" Ray muttered, a strange expression on his face.

Maintaining Argos required about four mutation energies—definitely more than a Level One undead.

"And the undead Raven seems to have gotten stronger," he murmured, feeling a bit shaken.

As Ray levelled up, his summons from the realm of the dead also grew stronger with him, especially as they continued to kill.

Ray casually handed two red pills to both of them.

For the first time, when Argos took the red pill, his face contorted in pain as if he were about to die all over again, but he soon returned to his usual indifferent expression.

Of course, that couldn't happen—Argos was already dead.

Even if he was "killed" again, he would regenerate. Ray might run out of mutation energy, but Argos would still return to the realm of the dead, or as Ray preferred to call it, the shadow realm.

"Attack," Ray casually commanded, pointing at the cat.

The two obediently complied and immediately launched a full-force assault on the Level Two cat.

The Raven's speed reached its peak, and in an instant, it appeared before the cat. Argos slashed with his sharp blades, aiming to cut the cat down.

If the sword landed, even Ray's defence might not withstand it, and he could be hacked to pieces. But just as the blade was about to reach the cat…

The cat slightly extended its paw forward, the blue flames on its tails burning even more vigorously.

The sword trembled, and Argos seemed to blur as the great sword phased right through the cat coming from the other side.

"This…" Ray's eyes narrowed in shock.

He could share Argos's senses, so he knew exactly what had happened.

Just as the great sword was about to slash the cat, it felt as if Argos's entire soul became blurry and faded from existence the moment the cat extended its paw.

"Is this spirit manipulation?" Ray's mind raced with countless thoughts, and he began to piece it together.

This was a special skill, one that even his Raven possessed but had locked potential. However, this Level Two Cat definitely had the ability to manipulate souls.

What was the weakness of the undead? It was the soul. The soul is eternal, and only the darkness from the realm of the dead can cleanse it.

This Level Two Cat's ability to manipulate souls could render all of Ray's summons useless.

But Ray didn't waver. He instructed his two undead to keep attacking.

The wind grew turbulent, and a terrifying storm blew in an instant under the Raven's manipulation, swirling toward the cat.

In response, a trace of disdain flashed in the undead cat's eyes. A blue ball of fire materialised in front of it, crashing into the storm with overwhelming force.

*Boom!*

As the two forces violently clashed, Ray watched in astonishment as the terrifying blue ball of fire grew even more intense. It directly struck the Raven, instantly reducing both Argos and the Raven to ashes.

Though they began regenerating, Ray's expression darkened. His mutation energy was draining rapidly—almost half of it had been consumed in just a few minutes.

"Forget it," Ray sighed with some pity but didn't cancel their summons.

He turned his fierce gaze back to the cat, a glint of determination in his eyes, and then descended from the sky with a violent stomp.

The cat, undeterred, seemed to accept the challenge. It looked at Ray with a voracious intensity and slowly rose into the air, directly clashing toward him.

*Boom!*

A terrifying shockwave rippled through the air as the cat's bones creaked, nearly turning to dust under the immense pressure exerted by Ray.

The force of his impact, coupled with the acceleration that more than tripled his strength, was too much for the undead cat to bear.

The undead cat roared in fury but was helpless as it crashed into the ground.

Doom!

The soil upheaved, forming a large crater where the undead cat and Ray had landed, transforming the surrounding area into a desolate wasteland.

"After all, it's just an undead," Ray sneered evilly.

If the cat had any brain cells and had chosen to flee instead of facing him head-on, Ray might have been in trouble.

As the dust settled, Ray could finally see the undead cat. It was riddled with injuries but still clung to life, its entire body engulfed in the blue flames.

Ray's hand brushed against the blue flame. It wasn't cold to the touch, but a shiver ran down his spine, making him back away with fear in his eyes.

It felt as though if he touched the blue flame any longer, his soul would be torn apart.

Meeooow!

The undead cat roared, causing Ray's ears to ring. However, unlike the first time when he had faced Raven, he was now able to handle it almost effortlessly.

The undead cat slowly floated up again, its entire body now encased in a blue flaming armour, glaring at Ray with utter rage—none of the playfulness from before remained.

"You must have been quite cute before the apocalypse, but now you must die," Ray muttered, shaking his head.

The ground creaked under his feet as he strode forward, moving almost instantly to the cat's side and delivering a powerful punch.
