Multi-Gene

It was a high level Dark haze beast. David senses had been reduced to a minimum therefore he didn't even know when the beast had reached that floor.

It's speed had been enough to almost insta-kill him.

David frowned deeply. His eyes showing the deep struggle in his mind. He was contemplating if he should release the hold he had over his blood circulation.

He had almost died, almost in one shot. His eyes revealed the well hidden fear in them and his heart beat inevitably rose, increasing his blood circulation and strength in the process but David was too far in thoughts to notice.

"Since I have started on this part, I must see through to it." His eyes revealed an unwavering determination and as he was about to enter the third floor, he changed directions immediately as he slid downwards back to the first floor.

He wasn't stupid. The leader had already seen him moving to the third floor and would have ordered the wolves to move there too.

He obviously wouldn't go there to die. He didn't enter the same room though, he moved to the next five windows and he quietly slipped in.

A horrible smell hit his nose instantly but David wasn't at all bothered by it. It seem this place was meant to be the toilet.

Moving quietly, he reached for the broken door and peaked out to the passage quickly and immediately taking back his gaze.

Three. Three mid level dark haze beast were going in and out of every room in that floor. It seems the park leader, the Alpha was meticulous and had stationed three mid level beast at this floor.

David smiled softly. Looking upwards, David frowned as there wasn't a single thing he could use to hold himself up there to launch a sneak attack if one of them entered the room.

Hm, just have to risk it.

Sneaking another peak, David stood quietly behind the door and he didn't make a move as he waited.

Seven seconds later, a mid level dark wolf charged into the room while growling with ferocity in its eyes.

David waited for a few seconds behind the broken door by the dark wolf side.

Seeing as there was no one there, it moved backwards and as it turned, about to exit the room, David moved.

He impulsively circled his arm around its neck and his legs on its waist and promptly squeezed with all his might.

The dark wolf instantly went limp as David continued to tighten his arms around its neck.

The wolf struggled, waving its paws that was in the air. With its lungs block, it couldn't even make a single sound.

Although the wolf was physically stronger than David, it had missed its opportunity when David had locked its head in. Thick hard hair fur of the wolf poked his body that it hurt but David didn't mind.

After a few seconds squeezing, a continuously crunching sound could be heard as David squeeze with all his strength crushing its lungs. The muscles in its neck couldn't hold out anymore.

The wolf's body instantly stiffened as it jerked. After a few seconds, the jerking slowed down after which, it stopped completely.

 Softly pushing the body aside, dragging it to one corner of the room. David breathed hard but he didn't rest. He took another peek at the entrance.

He waited silently as the second beast poked its head inside the building. David was not a single bit slow, it was as though he was an experienced master at strangling.

He repeated the process to the dark haze beast, after killing it, David's body and muscles was very sore and he could feel himself getting tired.

Peeking at the entrance, the Last beast had just entered the third room.

David calculated and immediately, he came out through the window of the fifth room and as he was about to enter the fourth room to wait for third beast to check out the room and then ambush it, David froze and he bent down at the entrance of the window.

A massive head suddenly came out from the window as it gazed upwards, attempting to determine his location.

'Sinister!' David chuckled in his mind but his hand wasn't the least bit slow.

Stab!

He instantly stabbed deeply at the high level dark haze wolf's throat. Blood instantly spurted out onto his face but as the horn pierced a few centimetres into its throat, it was immediately stopped and David could guess it had hardened its lung muscles. 

Howl!

A painful howl tore through its mouth. David only chuckled like a mad man as he swiftly punched its throat with all his , shutting it up and sending it back into the room, while simultaneously pulling out the horn and at the same time, he swiftly made his way to another side of the building like a monkey.

He knew his fish wouldn't have any effect on the beast, he was just that weak.

The wolf King was instantly enraged and it immediately destroyed the window with its sharp and massive claws thoroughly destroying the room in anger

The stab wound was serious but it wasn't deep enough to fully puncture its lungs.

Only a few neck muscles had been torn especially the veins. Some vaguely Important veins had being punctured, spilling out blood.

Blood spilled through the wound softly but that wasn't enough to immobilise it. It could only impede its combat ability.

A few seconds later, all the wolves in the building instantly rushed out swiftly as though under a sort of command and they instantly surrounded the building.

About 10 wolves growled, creating a type of cacophony that almost shook the foundations of the building.

The wolf King had stood before the building as it glared angrily at the windows and holes available in the building.

David stood quietly at a spot in the top floor, gazing at the evolved beasts outside. His expression was severe. He hadn't never imagined the beast to be smart to such degree.

He was almost down for two times. By the leader. David clenched his teeth. If he was using his true strength, he would have wiped the whole pack in five minutes.

But, he was training himself right now and he wanted to figure out what his harvest would be and what had compelled Lyster to take this path.

If his personality was a little more intense, he would definitely have stopped this experiment that may even turn out useless in the end useless.

Seeing that the Dark wolves were determined to remain outside the building, David walked straight, deeper into the building to the passage.. There was a supply box he needed to find.
