He Tian, the hidden descendant, carries the inheritance of the five arts of "mountain doctor, divination and martial arts", and follows his master's orders to enter the bizarre modern city. He originally wanted to fulfill his master's last wish in a low-key manner, but due to a misunderstanding on the street, he met Yang Musi, a shrewd and capable CEO of a technology company.
He Tian, who is dressed in civilian clothes and is incompatible with the bustling city, was initially regarded as a charlatan by Yang Musi. However, in repeated confrontations, he subverted her perception with his incredible ability - he could see through porcelain on the street at a glance. People's hearts are deceitful; when it comes to difficult and complicated diseases, his silver needle settles the fate of life and death; when it comes to business puzzles, he pinches his fingers to identify opportunities for misfortune and good fortune; when dangerous secret attacks occur, his fists and feet reveal the true meaning of martial arts; when the earth's veins move abnormally, he arranges arrays to stabilize the city.
As He Tian's five skills gradually emerge, the Xuanmen world hidden under the city is also unveiled. The game between the forces of good and evil, the fight for ancient secret treasures, and the mystery of the master's disappearance followed one after another, and the two were involved in a turmoil that spanned mortals and Taoism. From tit-for-tat to fighting side by side, from suspicion to life-and-death dependence, He Tian protects the common people with his five skills, and Yang Musi lights the way forward with wisdom. In the jungle of reinforced concrete, they write an urban Taoist legend about inheritance, protection and love. When ancient secrets meet modern civilization, when hidden masters meet professional elites, this encounter that started with a misunderstanding will eventually set off a huge storm that sweeps Jiangcheng.
