Unbeknownst to him, Xiao-qing stole the silver from the local treasury on behalf of her mistress for him. His brother, realizing the truth, turns in the silver. At the behest of the government and his family, Xu Xian takes everyone to the Bai manor, which is abandoned and does not appear lived in. The officials and soldiers go in the manor, and in her room, see Bai-niang, who disappears in a cloud of smoke.

Xiao-qing coaxes Xu Xian to see his mistress who, once again declares her love to the young man. Xu-Xian and Bai-niang consummate their relationship.
Winter and Spring pass, and the local Luzu festival is underway. Wang Ming lends the Xian family money and decides he wants it back. Xu Xian escapes while Bai-niang distracts him. Wang Ming intends on seducing her until Xiao-qing intercedes on her behalf. When Wang Ming turns around, Bai-niang is gone. Xu Xian attends the festival and there meets a Taoist monk from Mount Ji, who makes it his life's mission to save Xian from his "misery." According to him, Xian is bewitched and gives him three talismans to place on his body, his bedroom door, and into a flame, to save his humanity. When Xian tries to escape him, the monk surrounds him with a flame wall.
Xiao-qing is witness to the monk's intercession and informs Bai-niang, who gives her instructions for the evening, Xiao-qing is to poison the local waters, and the Xian family will make a medicine to cure the sickness. Xiao-qing questions her mistress, wondering if harming the people would be bad in Heaven's eyes, but Bai-niang brushes her off, stating that what matters to her is Xian's happiness. At midnight, Xiao-qing sneaks off to do as her mistress wishes and the monk appears at their home to magically force Xu Xian to use the talismans. Xian awakens and is about to burn the last one when Bai-niang awakens. After learning what has happened, Bai-niang guilts Xian and takes the talisman and burns it. The talisman's power reverses and paralyzes the monk.
The next day, the villagers go to the Xians' shop and buy up their medicine to pay off Wang. While the shop is busy, Bai-niang confronts the monk, and after a show of magic powers, Bai-niang traps the monk on top of a temple steeple, admonishing and belittling his magical power. To celebrate the success of their medicine, Wang invites Xian and the two ladies to his manor to celebrate. Xiao-qing points out that Wang intends to inebriate Bai-niang to sleep with her, and reminds Bai-niang that Realgar wine is poisonous to them.
Xu Xian, Bai-niang, and Xiao-qing go to the Wang home, and after revelry, Xiao-qing tries to remind her mistress about the wine but has an accident with a maid, who splashes the wine on her. Xiao-qing screams and runs into the Wang garden. Out of eyesight, the young woman transforms into a small green snake. In their drunken stupor, the two men force Bai-niang to drink the wine. She becomes severely ill from the wine and passes out. Wang has the madam put into a guest room to recover. Xu Xian checks on his wife, who has transformed into a white snake. He dies from fright while a green cloud pours out of the room.
Bai-niang goes to Heaven and begs the King of the Heavens to give her a stalk of magical grass to heal Xu Xian, but he refuses, citing her actions as evil and intends to imprison her in Heaven for her deeds. The Bodhisattva intercedes on her behalf, having pity on her, and she declares to give up her power for Xian's love.
