Every century, the dungeon awakens and drags people from different worlds into a fight for their survival. Parth, a pro boxer, is one of the summoned hundred, displaced by the dungeon’s latest awakening. After achieving the highest synchronization rate on record with a powerful magical artifact, he is thrust into the dungeon with a team of other isekai'd artifact wielders. He will fight men, beasts, and monsters, seeing just how far he can go. But only one can win it all and become the era's Centurion. In his old life, Parth suffered a string of losses, the tragic deaths of his parents compounding his downward spiral. But transported to this new world and given the incredible opportunity to wield power beyond his imagination, he'll accept nothing less than victory. Parth will win it all or die trying.
