Su Mo, the night shift security guard at a convenience store, died. Alive again. He was bound by something that called itself the "Mission Correction System" and was thrown into mission worlds that were on the verge of collapse. Other hosts save the world, and he specializes in dealing with all kinds of messes - cleaning up the mess for the original owner, repairing broken plots, and dealing with the fatal blame left by the previous host. The first mission: In the apocalypse where zombies are rampant, survive by assuming the identity of a bastard who just stole the last batch of vaccines from the base and is wanted by the whole city.
