The baby girl's cry was like a key, opening up another side of this world for him.
It turns out that the human world is not as peaceful and stable as it seems to the gods. Forgotten old gods awaken in the dust of temples, wandering souls with nowhere to return whisper in the corners of the city, and spirits from ancient legends walk quietly under the neon lights. These "abnormalities" that mortals cannot see or touch can easily hurt the equally extraordinary daughter in his arms.
In order to protect this sudden bond, Shen Jianshu had to regain the remaining Taoism that he had long abandoned. Holding a milk bottle in one hand and holding a sword in the other, he started cleaning up "abnormalities" in the world.
He killed a centuries-old tree demon that had caused trouble, and had three drinks with the lingering soul of an actor. He had seen urban legends born of desire, and listened to a river god narrate a thousand years of loneliness under a lonely lamp.
On the way to "clear the obstacles" for his daughter, Shen Jianshu gradually discovered that the truth behind his being demoted to earth, the mysterious origin of his daughter, and the increasingly frequent supernatural phenomena in the world seemed to point to an ancient secret that had long been forgotten by the fairy world.
