Three days before the heavy rain destroyed the world after my rebirth, I sold my house and stocked up on goods, and was ridiculed by the entire Internet for having "apocalyptic paranoia."

A year later, when the outside world was fighting for a piece of biscuit, I grilled a steak in front of the camera: "Welcome to the 'Ark' dungeon. The qualifications for entering the city: either you have a skill or... You are good-looking."
