Conquering the Tower Even Regressors Couldn't

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!
