Custom Made Demon King - Chapter 19: The Devoted and Professional Good Demon

This is not your usual isekai novel. it has my unique world background, unique power system and i am trying it make it a unique experience for every reader. :)

Athan, a 16-year-old boy, lived until he was killed for a stupid reason. (stupid reason & more in the prologue:v)

But it seems that fate had stored different things for him as after death as he transmigrated in the magical world inside a dead body of a boy with the same name and same facial features as him.

He also found out that a mysterious black whirlpool seemed to be inside him.

Was someone responsible for his transmigration? if so then who? and why? or was it pure coincidence that he got a new chance at life?

Taking place within a world of Measurements―superpowers owned from birth, with most being absolute trash.A world involving numerous secret organisations looking to take advantage of those rare and remarkable few possessing exceptional powers.When there exists Forbidden Knowledge better left unknown.When the discovery of said knowledge results in the inevitable; a world-ending catastrophe.‘Ignorance is bliss.’Fighting against the unrelenting persistence of the one who knows all.Before the tragic fate of the world repeats itself once more.―He must be stopped.

He died because he could not kill ‘him’.

He lived because he could not kill ‘him’.

Kang Yoonsoo, who had lived 999 lives by losing to the Demon Emperor.

Once again, he went back twenty years in time, back to his starting point.

“I will end this.”

Either he dies, or ‘he’ dies.

The thousandth life of a man who has mastered all the skills in the world begins.
