Stuck in the Tower

In a world where gates release monsters, Hyunsoo dreams of becoming a hunter who can enter the tower, but he is stuck working as a porter and living shield for E-Class hunters who treat him like a gangster’s lackey. After they exploit him until he is near death, he is summoned to the tower and brought back to life. Hyunsoo begins climbing toward the hunter he has always wanted to become. The tower lets people challenge it according to how many coins they have, and Hyunsoo discovers that his supply is infinite. He sets his sights on awakening on the hundredth floor and returning home, then begins his attempt to conquer the tower.
