In the corner of the bustling city, Zhao Yi is a "transparent person" who can be bullied by everyone. He quietly polishes his craftsmanship in a car repair shop, guards an old ancestral house, and lives a life without competing with the world. No one knew that this young man, who always lowered his head and was covered in oil, was actually the last sect leader of the "Xuanji Sect" that had been passed down for thousands of years, and he was also the "Zhen Yuan Zhe" who secretly guarded the Chinese lineage.
In an accident, in order to save the girl next door, he casually revealed a breath that alarmed the ancient family that had been hidden for many years; during the demolition of his ancestral home, he made light of the real estate giant's conspiracy, attracting the prying eyes of the mysterious organization "Tian Luo". From then on, the peace was broken, and all the forces that he had suppressed in the past emerged one after another - there were martial arts families who coveted the secret treasure of Xuanji Sect, there were capitalist oligarchs who tried to control the world economy, and there was a dark alliance from overseas trying to subvert the foundation of China.
Facing the ensuing crises and temptations, Zhao Yi no longer hides. He holds the "Dingyuan Ruler" handed down from his ancestors in his left hand, and the "Xuanji Technique" that cannot be analyzed by modern technology in his right hand. Starting from repairing cars, he gradually set off an urban storm. The former "transparent man" has finally become a being that awes the world's bosses, and he protects not only his own life, but also the peace and order of the entire China.
