Fahai, since Bai Suzhen flooded Jinshan Temple fifteen years ago, took the orphans left by her and Xu Xian and left Jinshan Temple and wandered around. Xu Shilin, whose name is Wu Nian, is the son of Bai Suzhen and Xu Xian. He is half snake demon and is talented and intelligent. He has never met his biological parents. He has followed Fahai since he was a child, but he has a feeling for this master that goes beyond the relationship between master and disciple, but he never dared to reveal it to Fahai until he was eighteen years old. When Fahai asked him to leave her at the age of 18, he uncontrollably confessed to Fahai, but from then on, Fahai avoided him like a snake, scorpion, and beast. Shilin left heartbroken and accidentally killed a person. The first time he killed someone, he was inspired by the blood to bring out the demonic nature that had been suppressed in his body, and he was forever doomed. . .
