In ancient times, a guard named "changpan warrior" was brought to the fort by a man named "Qinchenyuan" . The guard tells the story of how the family of "qin kezou" fought with him for a month to seize his body and kill him. The family hates the guts of the man who refused to fight for the family. The man asks the guard why the family made friends with the zhongli family, and the guard tells him that he is afraid someone wants him to know about it. He tells the man that the tower of the helan is part of the "horizontal force" , which is one of three major forces of the world, along with the radical "qilian fort" and the "taihang stream". The guard goes to bed, and when he wakes up, he finds the rat and the man waiting for him in his room.
