When the morning bell of Lingyin Temple rang, Jigong noticed that the fog outside Hangzhou was abnormal and ominous. It happened that A Niu, a young man from Liujia Village, asked for help. His mother was in danger because of the Yin Qi entering her body after carrying water from the ancient well at the entrance of the village. The water in the ancient well turned black and smelly. It was rumored that a woman in red was responsible.
Jigong and the young monk Biqing went to Liujia Village and discovered that the troublesome woman in red, Hong'er, was actually an innocent soul framed and locked in a well by Taoist priests hundreds of years ago. She was able to escape because the spell failed, and she became resentful and wanted to take revenge on the villagers. Jigong was moved by emotion and Xiaozhi by reason, and promised to help Hong'er find out the truth, seek justice, and temporarily calm down her grievances.
During this period, Elder Xuankong, the abbot of Lingyin Temple, came to help and resolved the yin energy in A Niu's mother. The next day, Jigong went to Hangzhou City to trace the whereabouts of the Taoist priests, but unexpectedly came across frequent cases of missing children in the city. He followed the evil spirit and finally found the evil spirit in a dilapidated house in the west alley of the city that had kidnapped children and wanted to use their souls to make medicine. After a battle, he successfully eliminated the evil spirit and rescued the trapped children, which also paved the way for the subsequent investigation of Hong'er's unjust case.
