Gui Hai Yida is a secret agent of "The No. 1 Village in the World". Because his father was eager for revenge, he practiced the Three Swords of Xiong Tian Xia and A Bi Dao, but he was unable to control his inner demons. Whenever he got mad, no one could easily control him for a while. He could only wait for him to slowly regain his consciousness. This time when Gui Hai Yida came back from a mission, he was unfortunately poisoned by a hidden weapon, and his inner demons were unleashed on the way. It was at this time that Ning Caichen met him.
