My name is Li Shangcun. I failed a secret agent combat mission during my lifetime. I was destined to die, but I was inadvertently reborn in a strange elevator. Behind the elevator is an unknown world that I can't afford to lose. Let's see how I set off waves of waves in the thousands of worlds behind the elevator door. Fantasy continents, mysterious worlds, and future starships will all leave my footprints, Li Shangcun.
