Chen Guan, a young Taoist priest who just came down from the mountain, moved into the home of his childhood sweetheart Lin Yu with his master's instructions to "see the world with a scientific eye." He pointed at the ceiling of the house and seriously analyzed the "magnetic field disorder", but Lin Yu laughed and scolded him for "adjusting the Wi-Fi signal." It wasn't until he pointed a finger that the fat orange cat that had been missing for three days jumped out of the closet with the ancestral compass in its mouth. Lin Yu was dumbfounded - there was a warning note stuck in the cat's fur: "Your grandfather's grave has been tampered with." On the back was the time capsule map they had buried together in their childhood.
The science girl's daily life has been turned upside down. Chen Guan uses "conservation of energy" to explain exorcisms and "psychological suggestion" to break through confusion. Behind the serious scientific fallacies, there is real metaphysics. The two regain a tacit understanding in a life of constant laughter, but they are also involved in layers of fog: the black market of magic weapons, mysterious organizations, Chen Guan's confusing life experience... When a childhood agreement leads to a huge conspiracy, let's see how these childhood sweethearts join hands to use "scientific" methods to break the evil situation, and on the way to protect ordinary warmth, they cultivate an incomprehensible fairy tale.
