Lu Chenzhou, on the surface, is the owner of a second-hand bookstore on the verge of bankruptcy in Yuntai City, but in fact he is the last descendant of "Dao Mei". He was adopted by his master since he was a child and practiced talismans and alchemy in a Taoist temple in the mountains. However, due to a sudden change in the "spiritual energy tide", his master disappeared and he was forced to go down the mountain and enter the world.
