The billion-dollar empire collapsed, and Lin Shen became a bankrupt rich man, but died tragically in a biochemical disaster that swept the world. When he opened his eyes again, he returned to the seven days before the end, and fell into a strange time loop - every time he died, the starting point of the loop would advance. With the capital, intelligence and cold reason accumulated through countless reincarnations, he tried to build an island of absolute safety. Until he discovered that the only "variable" in the cycle was the ordinary woman who always died to save him on the first day. In the endless cycle of death, he changed from a careerist who grabbed everything to the only "gambler" who knew all despair and hope, and was willing to bet on the last cycle to save her, and even the entire world. This time, it's either break the cycle or live and die with her in a real hell.
