Li Xuan traveled through time and became a poor Taoist priest, guarding the dilapidated Kongtong Temple and worrying about money for incense all day long. He appears to be lazy and greedy for money, and is full of modern complaints, but in fact he possesses astonishing abilities. He suppresses gangsters, exorcises evil spirits and catches ghosts while talking and laughing, but he can always turn all crises into "profit-making business." As the Weiyang Palace forces pursue him and the Wang family's strange ghost fetus incidents come one after another, Li Xuan is gradually involved in a world full of conspiracies and crises. On this seemingly unorthodox path of cultivating immortality, the shocking secrets hidden behind this world are quietly revealed.
