In Huaishu Hutong on a rainy night, Qi Feng, a delivery boy, ran into three puddles in order to catch an order, but was hit by a strange purple lightning. When he opened his eyes again, the yellow delivery clothes turned into ripped Taoist robes, the braised chicken in the basket was replaced by half a broken gold talisman, and a line of gilded characters popped up on the mobile phone screen: [Taoist system binding successful, novice task: repair the town sect gold talisman].
While others traveled through time with secret magic weapons, he brought a smartphone with 58% battery: metal detection can find the weak points of black iron, the strong light of a flashlight can drive away evil spirits, and even navigation can occasionally locate traces of evil objects. But there was a joke in the first level of Novice Village - he pulled the copper belt of the director Ma Xuanqing like a mysterious iron, almost tearing the Taoist priest's robe apart, causing all the disciples to fall to the ground with laughter; at night, when the golden talisman encountered a green-faced evil object, he panicked and raised his mobile phone to take pictures, but accidentally used a bright light to drive away the evil object, leaving Ma Xuanqing staring at his "iron box" and lost in thought.
From a delivery boy in an alley to a registered disciple of the Ma family in the north, Qi Feng used his mobile phone to break into the Taoist world: sweeping abandoned wells to find black iron, using flashlights to break evil spirits, and relying on system prompts to save mortals. In the funny daily life of "recognizing the wrong magic weapon" and "killing evil by mistake", he gradually understood the rules of the Taoist world. But as the active period of Yin Evil approaches, things that suppress evil in various places are getting out of control one after another. He discovers that his time travel is not accidental. Behind the mobile phone system, there is a secret that connects the two worlds...

In the end, he not only wants to repair the golden talisman and go home to pay the rent, but he also cannot help but want to protect Mysticism and the mortal world.
