Wang Dachui, an ordinary social worker who repairs mobile phones in a village in the city, his biggest dream is to save enough money to buy a non-stick pan. Until one day, he was touched by an orange cat with a "Mohawk" - not only could this cat speak human language, but he also took out a rusty "Cosmic Warranty Card" and claimed that his spacecraft broke down in the Earth's atmosphere, and Wang Dachui was the only "chosen repairman" in the universe who could repair it.
From repairing mobile phones to repairing spaceships, from dealing with urban management to toughening alien demolition teams, from fighting in communities on Earth to night markets on Mars, Wang Dachui's life has completely gone astray: he has to install anti-virus software for the AI system that can complain, put a tempered film on the alien emperor's "optical brain", and even help Martians solve interstellar disputes caused by "square dance noise pollution". What's even more outrageous is that this alien cat said that the universe is experiencing a "system collapse", and the cause of the collapse is actually someone using the neighbor's WiFi too much at the edge of the galaxy...
Under the threat of "exploding the earth if the spaceship is not repaired", Wang Dachui was forced to embark on a journey with Orange Cat. Along the way, he picked up an alien intern who firmly believed that "the earth is flat", took over an antique robot from the Taiwan President who loved to play "Love Business", and had to battle wits with a cosmic banker who was collecting debts. The so-called saving the universe is just jumping from one mess to another bigger mess - after all, when you discover that the moon is actually a forgotten power bank, and when you learn that black holes are just the "trash cans" of the universe, you know that this universe, like Wang Dachui's life, has long been ridiculous to the point of no end.
