The time traveler was bound to the "Survival System". He originally wanted to be a passerby in the world of immortality, but because pretending to be dead was too much like a "master", he was worshiped by the protagonist group. From then on, he performed a hilarious survival story in the Shura field where he was "forced to pretend to maintain his personality" and "desperately survive to avoid being exposed", while exploring the secrets of the strange system.
