The Jianghu sorcerer An Dongye was originally a half-baked man with poor skills. He accidentally predicted a fate for Tang Xiaomei, the daughter of the Tang Clan, which angered Tang Xiaomei and was beaten up by her. As a result, Zhou Xiaoli mistook him for a homeless man. An Dongye fell in love with him at first sight. In order to repay her, he pursued Zhou Xiaoli everywhere, but by chance he got the recruitment brochure of the Six Gates and met Tang Xiaomei again during the exam. After a hilarious exam process, the Six Gates admitted four newcomers, namely: An Dongye, Lei Jiaojiao, Peng Yuyan and Tang Xiaomei. The four bickered with each other every day and unknowingly trained to become a peculiar crime-solving team. At this time, the four great families in the martial arts world were fighting, and they found that the murderer was someone else. The four were ordered to investigate the truth. In the process of overcoming many difficulties and obstacles, they gradually realized the importance of unity. The four began to cooperate sincerely and show their strengths, and gave full play to the four people's mouth cannon skills to successfully subdue the murderer Tan Mo Liuying. However, everyone who thought it was a perfect ending was told that Greedy Demon Liuying was the guardian of the Qinglong Society, and the Qinglong Society's goal was the Tianzi Gate. In order to disintegrate the conspiracy of the Qinglong Gate, the four were ordered to sneak into the Tianzi to listen to lectures, while An Dongye was undercover and pursuing Zhou Xiaoli, and the truth of the case gradually surfaced. To everyone's surprise, the murderer turned out to be Qiu Baifu, the vice president of the Tianzi Gate. All this was to allow the Jin Kingdom to infiltrate the Song Dynasty court. After this case, the four people of the six gates made great contributions, and Song Dongye and Zhou Xiaoli also successfully dated with the help of Tang Xiaomei. At this time, Tang Xiaomei found that her feelings for Song Dongye had changed. Just as An Dongye was sitting in a dream of being embraced by his left and right arms, Zhou Xiaoli's husband Yu Tianye, who had been missing for many years, suddenly appeared again. His appearance broke the love triangle and seemed to be related to a bigger conspiracy...
