An unlucky guy discovered the shocking secret that the entire world of immortality is an "alien breeding farm." He didn't want to be a "meat pig", he just wanted to survive. As a result, he became a "devil" who screamed and killed all over the world. He can only drag his body and rely on an alien "broken knife" of unknown origin, and he is on the run in the abyss, monster piles, and pursuits all over the world, desperately looking for a chance of survival, and trying to find a way to overthrow this damn "breeding farm"!
