During the reign of Ningzong of the Southern Song Dynasty, the imperial court settled in the south of the Yangtze River. The Kingdom of Jin was eyeing it, and the Mongolian cavalry gradually showed its talents. There are rumors in the world that the fragments of the "Martial Arts Summary" that have been lost for hundreds of years have reappeared in the world, and they contain secrets that can turn the world around - either peerless martial arts, magical weapons, or military formation maps that can overturn the country.
Jiangnan hero Lu Tianyuan was accidentally involved in a dispute over the remaining pictures. He adopted his best friend's orphan Cheng Ruhui and raised him with his own son Lu Jiansheng. Fifteen years later, the Blood Hand Alliance raided Guiyun Village, and Lu Tianyuan died in the battle. Before his death, he handed over half of the fragmented picture to his second son, and left a riddle: "In front of the misty rain building, there is something created by heaven's work."
Lu Jiansheng has a strong temperament and excellent swordsmanship, and vows to avenge his father; Cheng Ruhui is thoughtful and proficient in mechanism skills, but his life experience is a mystery. The two embarked on the road to the rivers and lakes, only to discover that behind the residual pictures was not only a martial arts grievance, but also a spy mystery that spanned Song, Jin, and Mongolia...
The temple is high and the rivers and lakes are far away, who plays chess? Who is the pawn?
