The three pillars of Daliang, Hu Chao, and He Chao were resting and recuperating on the surface, but undercurrents were surging behind the scenes. Qing Ran, an abandoned disciple of Shaolin, was originally Zhao Tingqing, an orphan from a Jiangnan aristocratic family. His family was destroyed by the remnants of the Hu Dynasty (the demon sect), and he was implanted with a magical spirit. Carrying the demonic energy, he became the target of both good and evil. However, he possesses the Ming martial spirit and Shaolin's unique skills, and is the future leader of the Buddhist sect. Mo Quan, a genius from Wudang Mountain, was actually an undercover agent of the Hu Dynasty. His memory was blocked and he was adopted by Wudang as an orphan. Together with his best friend Lin Tianyi, he ranks among the top righteous young men, and his martial arts ranks among the top three among the younger generation in Wudang.
A mysterious letter leads to the Wudang murder case, and Mo Quan is wrongfully imprisoned. Lin Tianyi leads the investigation, but encounters a mysterious killer and strange messages, which gradually exposes the secrets of the Three Dynasties. Qingran met Naizi, the young master of Hechaohe Taoism Society, during his escape. The three of them met Mo Quan and became close friends. From the catastrophe in the Shaolin Temple and the Taoist pursuit, to the southern invasion of the Hu Dynasty demon sect, the death of the Liang Dynasty emperor in battle, to the eyeing of Western technological forces, the teenagers have gone through many hardships. After Mo Quan fell off a cliff, his memory was awakened by the Hu Dynasty, but he was caught in a dilemma because of his friendship with everyone. In order to save their close friends and protect their country, Qing Ran, Lin Tianyi, and Nai Zi united with Buddhist and Taoist forces and the Liang Dynasty's military and civilian reforms to liberate productivity through civil and military methods and mobilize the power of the country to fight against foreign enemies. In the end, everyone reunited at the front line of the Great Wall, and Mo Quan turned against each other. They joined forces with the inside and outside to defeat the Hu Dynasty and the Western invaders. They protected the peace of Middle-earth with blood and loyalty, and wrote a legend of a young hero that spanned three dynasties and dealt with good and evil.
