Solar radiation mutates animals around the world, marine creatures land on the earth, and snakes, insects, rats, and ants attack humans, becoming either highly toxic or infected. Li Hao was reborn and returned to three days before the end of the world. He sold his real estate and began to hoard materials crazily to build a doomsday fortress. When the doomsday comes and others are killing for the little food and drink, he is the only one who is drinking high-end red wine, eating steak, and hiding in his own fortress, feeling very comfortable. When food is scarce, only nurses, doctors, and technicians can enter the building and be sheltered. Xie Xin: Master, do you like me wearing yoga pants? Ying Huanhuan: Don't drive me out, I can do whatever you want.
