Most people would jump at the chance to redo their greatest failures, but Jaehwan knew that a second chance was just a beautiful way to give up. When the mysterious Towers turned Earth into a monster-infested hellscape, every other hero used a Regression Stone to flee into the past, leaving Jaehwan as the sole survivor of a doomed timeline. For ten grueling years, he fought through a solitary nightmare to reach the final floor, only to realize the truth: the Tower was never meant to be conquered. It is a factory, humanity is the product, and the past everyone ran to is nothing but a digital illusion. Armed with nothing but a sword and a refusal to break, Jaehwan is ready to slash through the fabric of reality itself to punish the beings who turned his world into a game. He is the man who stayed behind, and he is coming to show the universe that a single, stubborn human is more dangerous than any god.
