The Mystical Biological Mother Returns, the Villainous Sons Stand Up Straight

Gu Qingyin returns to the Huo family villa after a mission only to be confronted by a man who identifies himself as Huo Xingye, the current Family Head of the Huo family. She quickly realizes that two days in an alternate dimension for her was twenty years in the real world. Her husband Huo Yun Jing died in a car accident ten years ago, and her six-month-old son has grown into the man before her. A paternity test confirms their relationship. Gu Qingyin explains she is a Celestial Master who chases ghosts and subdues demons. She had a marriage of convenience with Huo Yun Jing, consummated it, and became pregnant. She left for a mission when her son was almost six months old after an argument with Huo Yun Jing who wanted her to stay home. The mission led her into an alternate dimension, and when she emerged two decades had passed. Huo Yun Jing had died and her son now runs the family.

After the test Huo Xingye takes her to dinner. She gives his assistant Xue Ning a protective talisman. She then goes to an antique street to buy cinnabar, yellow paper, and jade pendants, planning to make protective charms for her family. She spends the evening crafting three jade pendants. Days pass without Huo Xingye visiting so she decides to go find him. Just as she is about to leave she receives a call from Qin Zhen the owner of an antique shop she frequented years ago. He asks her to save the daughter of his friend Xu Chaoyue who is possessed by a ghost for five days. Gu Qingyin agrees and goes to the Xu villa.

At the villa heavy ghost qi pervades the second floor. The child's father Old Xu is skeptical of her abilities and prefers to wait for a renowned Daoist from Longhu Mountain. Gu Qingyin warns that the ghost is about to act and insists on taking the case. Old Xu agrees to pay ten million if she can save his daughter. Gu Qingyin goes upstairs and uses talismans to protect Qin Zhen and Old Xu. She then enters the child's room to confront the possessing entity and exorcise the ghost. The story ends with her preparing to deal with the ghost and save the child.
