Master Ni is the prototype of a Taoist master who has been reclusive for many years. In order to fulfill his master's last wish and his own spiritual practice, he went down the mountain to the bustling city. In this era of collision between technology and tradition, he not only has to face the various challenges of modern society, but also has to overcome tribulations and practice in the world of mortals to resolve a Taoist crisis that has never happened in a thousand years. By treating illnesses, rescuing people, and exorcising evil spirits, he gradually uncovered a huge conspiracy involving ancient and modern times, both at home and abroad, and finally found the balance point between tradition and modernity in the modern city, completing the spiritual transformation from being born in the world to joining the world.
