Zhang Yiheng, an eight-year-old Taoist saint, lives in his aunt Lu Youyou's house with his past life memories and Taoist system. On the surface, he appears to be a cute academic master, but in fact, he practices "Nine Yang Magic" behind closed doors. He used Zhu Youshu to cure diseases, suona to attract birds, punched sandbags, and subverted everyone's perception with his "reverse Tiangang" operation. From subduing wild monsters and slapping Chinese martial arts coaches in the face to slaying vampires across borders and preaching to the world, he protected the unreliable Lu Youyou while using his body as a child to lower his dimensions and attack powerful enemies from all walks of life. He promoted Taoism in modern cities and eventually became a living Taoist ancestor respected by thousands of people. He wrote a passionate legend of "doing the most wild things with the most milky face".
