Grandma Zhou at the sugar water shop at the foot of the mountain guards an old pot left by her late husband. The spiritual veins of the Yunxiu Sect are withered; Sect Leader Xuanzhao comes to snatch the pot. Xie Wujiu, an injured sword cultivator, drinks a bowl of sweet soup and, recovering, switches sides. Baili, an injured little demon, also comes to steal candied dates to wash the pot and pay off the debt. Following the spiritual veins all the way to question further, they uncover the old case from a hundred years ago where Xuanzhao closed the Guixu Gate and sealed demon bones and grievance tides into the spiritual veins. The Immortal Court tries to tempt Grandma Zhou with longevity to take over as the Gatekeeper, but she flatly refuses; Xuanzhao admits his mistake and resigns, and Zhou Man, who guarded the seal for a hundred years, also returns. In the end, the spiritual veins are returned to be shared by immortals, mortals, and demons, the sugar water shop reopens its pot, and immortals line up to buy soup.
