Yuyang Gao

Young chess prodigy Zhu Dingcai is on his way to the capital to petition the imperial court, accompanied by his protectors Gao Sheng and Wei Jingjing. When they arrive in Yulin, Shaanxi, they encounter a young man named Wen Tingjian, who is being mysteriously pursued by an assassin and urgently seeks their help. Kind-hearted and quick-witted, Zhu Dingcai uses strategic principles from Chinese chess—particularly the tactic of "resolving a kill and counterattacking"—to unravel a complex case involving a fierce dispute over business ownership rights.

Zhu Dingtai, the legitimate grandson of the Ming dynasty's Anhua Prince, risked his life to travel to the capital and file a petition to seek justice for his grandfather and father. However, the journey was fraught with danger. Along the way, he had to use his wits and courage, subduing the innkeeper, Tuo Jiu, and even the three martial arts sisters and the Internal Bureau's hundred-household chief, who were sent to assassinate him. In the end, they were all moved by his benevolence and righteousness.
