The protagonist Xu Xing's parents died when he was young. He escaped with his sister Xu Yin and was rescued by Guangchen. Every hundred years, the gate of hell opens. In order to prevent the world from chaos, Guangchen chose to fight alone. He sent Xu Xing and Xu Yin to his friends in Lingshan to raise them and practice Taoism. Xu Xing witnessed with his own eyes what he cared about. I have always been reluctant to believe my personal death. A hundred years later, the gate of hell opened again. In order to prevent the destruction of the world and find "that person", Xu Xing and Xu Yin were ordered by their master to go down the mountain to do a mission to kill ghosts and obtain the "pre-stone" that sealed the gate of hell. Later, they met again with "that person" who they thought about day and night.
