In AD 3024, in the seventh sector of the Interstellar Federation, 16-year-old Lu Muye took the medical memories of his previous life and a piece of mysterious white jade and traveled through time to become a wasted boy whose engagement was broken off. On the surface, he is a docile and well-behaved "little sheep" who doesn't even dare to kill a chicken, but in fact he masters ancient Chinese medical skills that surpass interstellar technology for thousands of years. When the wealthy daughter of the Interstellar Federation stepped on his face and broke off the engagement, he just smiled; when the experts from the medical group laughed at him for not understanding modern medicine, he casually cured the terminal illness with a silver needle. The mysterious espionage organization, the darkened ex-fiancée, the strange interstellar plague... All the enemies thought that he was still the good-for-nothing who was at the mercy of others. But when they finally woke up, Lu Muye was standing on top of the stars, with medical clinics all over the galaxy behind him. He said: "I pretend to be innocent and kind, but I also have a good face. You guys, let me treat one of you, or a pair?" This is a counterattack history of a good-for-nothing miracle doctor who appears to be gentle and kind, but is actually ruthless and decisive.
