Lin Feng, a retired soldier, was supposed to return home with military glory, but he was plagued by bad luck - he was hit on the head by bird droppings when he went out, choked on his throat when drinking water, was pressed into bed by ghosts in the middle of the night, and broke his leg while walking on a flat road. When he was desperate, he found Shen Qingxuan, an old Taoist priest in Poguan on the outskirts of the city. Only then did he realize that the killings on the battlefield were too heavy and the resentful spirits were lingering. If they were not resolved, his life would be in danger.
Desperate, Lin Feng joined the Taoist sect and became a disciple who had become a monk. There is a pair of twin senior sisters in the Taoist temple, Shen Lingxue and Shen Lingyue. They are born with the same cold and graceful appearance, but their temperaments are completely different. Senior sister Shen Lingxue was cold and taciturn. She was cold and distant towards his junior fellow apprentice. She frowned and turned around before finishing three sentences. Junior sister Shen Lingyue is gentle and virtuous. She keeps the Taoist temple in order. She also likes to make sweet pastries. She is a bit naughty and cute. She always takes advantage of Lin Feng's distraction during sword practice to stuff a cool leaf behind his neck and laughs at his startled appearance. What no one knows is that these twin sisters are burdened with a severe fateful curse - because they were born on Twins' Day, they will either die alone together in this life and break all ties in the world; or they will find a man who is at the junction of yin and yang. Only by serving one husband together can the two sisters break the shackles of fate and live a stable and smooth life.
From then on, Lin Feng followed his master and his two senior sisters, traveling through deserted villages, old houses, and haunted places to resolve the grievances of the living and save the souls of the dead. There are strange smiles in deserted villages, ghosts in red clothes in ancient houses, and resentful corpses in reservoirs. One after another, supernatural events occur one after another. Holding a mahogany sword, he followed Senior Sister Lingxue to identify evil spirits and determine their location. He relied on Senior Sister Lingyue to protect him from the evil backlash, and he was struggling on the edge of life and death.
