After the nuclear war, ruins stretch across the landscape in the apocalypse. 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 aftermath of constant radiation. But for Jiang Chen, this place is heaven. Mansions standing tall, luxurious cars parked on the street, high tech products and gold abandoned everywhere. What?

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 possesses the ability to travel through space and time, as he witnesses the creation of an empire stretched across space and time...
