Emperor Jiajing was obsessed with Taoism, Yan Song controlled the government, and the court was filled with chaos. {Shen Jinghan} was born in the Jinyiwei family. Due to his wisdom and bravery, he was promoted to Qianshi, specializing in investigating official corruption. On the way to investigate the case, he ran into the daughter of the guilty minister {Su Wanning} - her father was falsely accused of treason and executed because of the impeachment of Yan Song. After Wan Ning escaped by chance, she was determined to overturn the case for her father. Shen Jinghan was touched by his experience and decided to join forces to fight against the epidemic. The two fought at the tip of the knife and were repeatedly hunted by Yan Song's gangsters, narrowly escaping death. Shen Jinghan used the power of the Jin Yiwei to protect Wan Ning, went deeper into the tiger's den, and uncovered the shocking evidence of Yan Song's collusion with Japanese pirates. When the evidence was presented to the emperor, Emperor Jiajing was furious, the Yan Party was destroyed, and the injustice was avenged. Shen Jinghan was promoted to commander, purged the Jinyi Guards and clarified the officialdom; Su Wanning stayed in Beijing to open an academy, passing on her father's loyalty and martyrdom through pen and ink.
