The End of the World: Starting from Escaping from the Slave Cabin

Two hundred years ago, human civilization collapsed overnight. The aliens rise and humans are reduced to livestock. Yu Fei traveled through time. There are no cheats, no system, not even a novice gift pack. Well, the system actually exists. But its only function is to take a beating. Being whipped, mental strength +1. Being bombarded by fireballs, defense +1. The great magician used spiritual magic to force him to death. His spiritual power was +5+8+7+7... Yu Fei: "Old man, haven't you eaten? Try harder!" As a result, a slave who was snatching swill from a pig pen began to commit suicide. He has a mean mouth, weak hands, and is dedicated to hitting the muzzle of a gun, chasing the most dangerous person in Lisuo City for a beating.
