Tang Yuanyuan, a young Taoist priest who became a courier, took an order of "toys" and delivered them to the ghost market archway, directly traveling to a different world where talismans are used as currency. He thought he was the best, but it turned out that people in that world didn't understand basic Taoism - the "Huang Ting Jing" he had memorized by heart became the ultimate secret book. The aloof recipient Pei Wujiu pressed him step by step, insisting that he hand over the "real goods". As one chases and the other escapes, the secret of Shipai Fang gradually comes to light, and Tang Yuanyuan is promoted from an unlucky guy who delivered the wrong goods to a fake Taoist respected by thousands of people.
