Live Broadcast: I Said I Have Never Killed Anyone, and the Polygraph Test Became Popular

Jiang Feng, a student at Jiangbei University, is a top killer. During a street interview, he was asked if he had ever killed anyone. The polygraph test became popular and attracted the attention of the law enforcement bureau. He participated in the live broadcast and followed the filming, showing off his versatile skills such as fighting, medical skills, and detoxification, and successively foiled Zhang Deye's plot to kill his father and seize property, Yun Lingshan's revenge, and Lin Dafu's strong purchase of land. During this period, he anonymously donated money to build a Hope Primary School to protect children in mountainous areas, and gradually fell in love with the host Xu Luofei. In the end, Jiang Feng subdued all the villains, fulfilled his charity promise, and joined hands with Xu Luofei to protect justice and warmth between the ordinary campus and the secret mission.
