Read the light novel I have a Mansion in the Post-apocalyptic World to have a deep understanding of ruins stretched across the landscape in the apocalypse after the nuclear war. If you accidentally survived on the wasteland, then you must be ready to face the endless hunger, ceaseless dangers, the mad zombies at night, and the peculiar mutant creatures that are the aftermaths of the constant radiation. But for Jiang Chen, this place was heaven. Mansions stood tall, luxurious cars parked on the street, high-tech products and gold abandoned everywhere. What? You were the president of a game development company before the war? You were responsible for the development of the 3D virtual reality online multiplayer game? Well, that’s great, why don’t you come work for me. The salary is two pieces of bread a day.iPhone? Ultra-thin design? Don’t you see that the phone I invented is thinner than condoms? Aircraft carrier? Fighter jets? Oh, I have those things as well, but they are designed for space combat. Watch the story of Jiang Chen, who possessed the ability to travel through space and time, as he witnesses the creation of an empire stretched across space and time.
