Taoist priest Xuanchen is not a native of Fengxi Village. Sixty years ago, he was a young Taoist priest named Li Shouyi who followed his master to pursue a "living creature" and came to Fengxi Village. His master died in the confrontation with the "living creatures", and before his death, he passed on the mission of guarding the seal below the village to him. This seal is not stable and requires "sacrifice" to strengthen it every once in a while. For decades, Xuan Chen used various methods, even some methods listed as forbidden techniques by the Taoist sect, to maintain the seal. He has witnessed too many deaths and strange events, and the birth of the protagonist Chen Yuhua is closely related to him. When the seal was loosened more than 20 years ago, in order to completely stabilize the seal, Xuanchen used a forbidden technique to graft a trace of the "root" of the sealed object onto Chen Yuhua, who was just born at the time, so that Chen Yuhua's fate was connected to the seal and became a living "tighten object". This is also the reason why Chen Yuhua has been frail and sick since childhood and can see "dirty" things. Xuanchen adopted or semi-supervised Chen Yuhua as he grew up, partly out of guilt, and partly because he needed to train Chen Yuhua to become the next guardian, because his own life was almost exhausted by secrets and curses...
