Yin Contract: Soul Binding

The male protagonist Qi Hua is a yin exorcist with yin and yang eyes. The use of magic will continue to overdraw the yang life span; the female protagonist Nian Youyou is born with a very yin fate that is full of affinity and yin energy. It is easy to attract yin objects. She has worn a lotus pattern silver lock plate made by Pei Ye since she was a child, which has a double seal to suppress her life. The villain Pei Ye is the rebellious disciple of Master Qi Hua. He also has yin and yang eyes. He advocates opening up the yin and yang to freely circulate yin energy. He uses his own body as a port for the underworld, continues to lose himself, and wants to replace himself with the special destiny of Nian Youyou. ​The core of the story:​The cost of exorcising evil and saving people, the two routes of yin and yang balance, the pull of fate and two-way protection.​
