In the 14th year of Chenghua in the Ming Dynasty, Tang Fan, a sixth-rank official, and Sui Zhou, the general flag of the Jinyiwei, joined forces to solve the unsolved murder case of the son of the Marquis. The two became famous for a while and formed a friendship. Although he was famous, Tang Fan, who was an honest official, still rented a house to live. The virtuous landlord Zhang died in a secret room. It seemed to be suicide, but there were many doubts. After an investigation, the husband of the deceased, Li Man, was finally captured. Soon Tang Fan went to Henan to investigate the case and learned that many people had disappeared near the imperial mausoleum of the Northern Song Dynasty. The real murderer was Li Man who escaped from prison. After a desperate battle, Li Man was arrested again, but Li Man and his minions seemed to be just pawns. Immediately, major cases continued in the capital and the local areas, such as the "death of the minister and his wife" and the "abduction of the prince". The power of the court was hidden behind them. Tang Fan and Sui Zhou finally revealed the truth. The man behind a series of cases was Shang Ming, the governor of the East Factory who was plotting a rebellion. He used the power in the government and the opposition to create chaos, eliminate dissidents, and cultivate wings, intending to lay the foundation for rebellion. Tang Fan and Sui Zhou worked together to crush Shang Ming's conspiracy and were rewarded. The two continued to serve diligently, be fair, and punish evil and evil down to earth, and continued to work hard to bring peace to the people.
