Doomsday Chinese Restaurant

If the world is a game, then the destruction of dinosaurs, the birth of mankind, and the advent of the end of the world are just the beginning of a new expansion pack for this game. If this world is nothing more than a testing ground, and humans are no different than microorganisms in a petri dish, then where should humans go in the new era? How will it develop? "Speaking of which, why is the introduction so serious but the main character is a restaurant owner? Is it possible to survive by eating Chinese food in the apocalypse? Can the setting not be such a joke, you bastard?"
