Lin Feiyu, the head of the spiritual sect, went down the mountain to enter the world in order to complete his experience in the world of mortals. When he first entered the world, he had nothing to offer and temporarily stayed in a friend's house. By chance, he became a shared tenant. He relied on the ancient forensic medicine skills that had been passed down for a long time to save people. He took the initiative to refuse the high reward offered by the other party and chose to establish himself in an ordinary security position. After seeing his superb medical skills, the successful female entrepreneur sincerely invited him to go to the south for cooperation and development. Along the way, Lin Feiyu showed his extraordinary skills several times and successfully solved various problems, winning the respect of seniors in the industry. With his inherited skills, he started a wonderful life of urban experience.
