Programmer Liu Yi was reborn as an abandoned military satellite 500 years later. He met the wasteland girl He Xiaoxu and turned into a "plug-in system" to assist in survival. They gathered Arlene, Bai Xiayang and others to form an alliance, and while fighting against mutant beasts, extraterrestrial gods and deep-sea threats, they gradually revealed the truth of the doomsday - the plan of the lunar "pioneer" civilization to clean the earth. In the end, everyone took a starship to face the devastating blow of the moon, launched a counterattack for survival, and wrote the last epic of mankind's struggle.
