In a world overrun by monsters and mysterious dungeons, Na Sunhoo fights alongside other Awakeneds to defend humanity from destruction. But during a catastrophic battle, he loses his life—only to be met with a strange message asking, “Initiate Time Regression?”

Given the opportunity to start over, Sunhoo is sent back to the past with all his memories intact. This time, instead of simply preparing for battle, he focuses on earning enough money to purchase the land where future dungeons will emerge, planning to eliminate them before the monsters can even appear.

With countless innocent lives hanging in the balance, Sunhoo races against time to build his fortune, rewrite fate, and put an end to the monster threat forever.
