MTL - Joy of Life - Chapter 12 Simple and rude explanation

His friend and his wife betrayed him. The only thing left to him was his massive debt and his precious daughter. He was without hope as he lived at the bottom. However, a last chance had come to Sungyoon. He was a ‘man without a heartbeat’, and he will explore the Moon’s Labyrinth. He’ll explore the parts of the dungeon yet to be seen!

One drunken night, my friend blurted out something absurd.“Su-Hyeok, I’ve regressed.”“Regressed?”“Yeah, I’ve returned to the past.”“Are you out of your mind?”“You’re humanity’s only hope.”Then, I was dragged into the tower for real… but who cares?Regressor? Tower? Trials? What are those supposed to be?An overwhelming talent is about to crush everything in its path!

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?
