Ren slowly stood up with a bitter smile on his face, "It seems like it was still not over"
With a sword in his hand and determine expression on his face that soon dissappear and replace by indifferences.
"Come at me, You shall be my source of strength in this early phase of the apocalypse that would lead me to grew stronger."
While the 2 zombie look at him hungrily and charge straight at him, Ren sidestepped the first zombie causing it to staggered forward and put his attention on the second zombie; He dash in succession after sidestepping the first zombie and leave it behind, the second zombie slash his sharp nail at him.
Deflecting it, he kick the zombie and send it flying; he followed the zombie as it fall down he slash his sword at the neck. Using all of his strength, the sword rip the head off this time he succeed in first try.
But before he could've even celebrate, his survival instinct kick in, he manage to acquire it after experiencing a lot of life and death exprience.
He hurriedly jump to the side, barely avoiding the zombie bites. He saw the zombie flying at his previous location, it was obvious it tried to pounce at him.
"That's a close call, I should be even careful next time."
He stood up slowly, while holding the sword on his hand. He look at the zombie infront of him that almost bite him, his eyes was cold and emit a dangerous glint that the mindless zombie couldn't comprehend.
Fatigued, also hit him now. He was extremely tired, he wan't to end it as soon as possible.
Clenching his sword, he dash at the zombie but in slower pace as fatigued hit him already.
He felt his legs and arm giving in at that moment, but the his strong will allowed him to move though it was hard.
The zombie already manage to stand up and his back at him, using this opportunity he strike it with the last remaining strength he had.
Then he fall heavily, he felt his consciousness slowly fading away. At that moment, he heard a familiar voice but he already lose consciousness.
His last thought was.. 'Was this the end? I ha.. dn't..... ev..' before he even complete his thought he pass out.
...
Ren opened his eyes widely, and saw a unfamiliar ceiling, he quickly gone up and look around.
"This?.. Where am I? Was I saved?" This room look neither the heaven or hell, it was not even a room but it was a bit similar.
Confusion was obvious on his face as the door opened, "Oh, your awake already Ren? I heard noise outside while I was hiding in my apartment and saw you unconscious." The man voice explain
At that moment, everything became clear as his mind was still unstable he wasn't able to think about this simple thing.
He knew this man, and he was none other than Brian Loin his next door neighbor.
"Thank you, If weren't for you I might die.." Ren thanked Brian.
Then at that time, he recall the zombie; He slowly get off the bed and goes outside to find the zombie.
"Hey, man just rest for abit."
But Ren reject and rush outside, But the moment he open the door he immediately close it.
"That was close one." at the same time look at Brian, "Where's my sword?" while Brian pointed simply at table.
Ren sigh in relief and pick it up, Turning to Brian.
Ren looked at his eyes, then he opened his mouth and say something.
"Thanks, and... Don't go outside and be careful." With those words, Ren leaves without even turning back.
There's not a single zombie outside, walking for a few seconds and reach his location where he fought and kill 3 zombie and where he pass out.
There lay 3 zombie, the blood was already dry, After all hours had already pass when he killed it.
Dissecting it for few minutes, he found an tiny object that was slowly resembling an shape of oval that emit a mysterious green light.
Brian didn't came with him as he was doing something, But before he left he said don't leavr his apartment till he knock.
It took atleast 2 minutes before he gathered 3 oval shape object in each of the zombie, Ren put it inside of his pocket. Next he return back to his apartment room passing by Brian's.
Opening the door and locking it, he walk on the living room and sat in the sofa. Ren place his sword in the table right infront of him, while he took out the 3 green oval unknown object that he took on the zombie body of his pocket.
Ren took a long deep breath and ate it, he shallowed it in his throat, then Ren slowly wait.
1 seconds pass
3 seconds pass
Nothing happened, but after 5 seconds something change inside of Ren. He felt an heat all over his body as if he was showering in a lava, with the heat came with an immense headache, but it was still not enough.
His skin, muscles, bone start to tear and crack. Ren felt an Immense pain that almost everybody couldn't endure, but with his experience he experience something worst than this.
The pain feels like it last for eternity but seconds only pass by, blood slowly slip out of his body although his internal organ and cell was not affected.
This last for an hour before his whole body started to transform, but the pain hadn't dissappear.
All Ren could do is to endure the pain for an hours.
After 1 hour of Immense Pain that felt like last forever, Ren's body started to transform.
His skin, muscles slowly being repair and strengthen at this moment.
His skin that was sipping blood was healing in incredibly fast-pace.
His muscles also start being restore was replace with a new formidable muscle.
While his cracked bone was not destroyed, But started to repair and strengthen further.
His whole body felt reborn, although only the external part only that was been transformed not his whole body all together.
At this moment, Ren could felt his new profound strength.
He had reached the Athlete stage, He was now a early stage of Athlete level.
His Strength, Speed, Stamina, Reflex, Reaction, Etc..
Was at level of proffesional level all together that focus in each field equally.
But this wasn't enough at all, his goal is reached the peak of top athlete level.
At that level he was at the limit of human, same level of the top athlete that mainly focus in each field. But he was equal in each power system, He would reached the level of each strength, speed, etc of top athlete.
Above that would literally impossible to reach before the evolution phase began, after all the Core is still not form.
Early phase had only form an shattered core, Evolution phase, also known True Start was the beginning of the true apocalypse.
The growth phase of the zombie would begin, only after a week of start of the True Start is the Core is discover.
That help human to surpass their limit and reach the level of Extraordinary also known as the Limit breaker.
There's dozens rank here that human of his past life had and not reached.
The True Start is where the evolve zombie appearing, the true potential of the zombie is completely unlocked at that stage and no longer a weak zombie.
[Ranks of the Human and Zombie wouldn't reveal, I don't like spoiling too much.]
