In the summer of 2017, outside the solar system, some super martial arts clans located in Ziwei constellation wanted to build an unprecedented large-scale tactical transmission route to facilitate their development of the southern galaxy. However, that route coincidentally passed through the earth, which, therefore, would be demolished. Unfortunately, earthlings had no idea at all except an old faker. In order to protect the earth and save the whole mankind, the old faker chose a 14-year-old boy, Li Mu, who had no parents, to learn his lifelong martial art skills, and then, he sent him to a low-level martial arts planet in Ziwei constellation and let him use another man’s identity of Taibai county magistrate in the Western Qin Empire. Then the youngest county magistrate Li Mu began his practice alone. Could the 14-year-old boy shoulder such a great responsibility? Could he ultimately protect the earth and save all mankind? What did he experience during that adventure?
