In the third year of the Great Era, Emperor Xie Zheng fell off a cliff because of "White Moonlight" Lin Weiwei. He found the palace maid Jin An in the Huanyi Bureau and made her a substitute concubine. In fact, he secretly tested the Yun brocade silk ribbon in Lin Weiwei's belongings, which involved the old case of the Yun family being falsely accused of collaborating with the enemy and exterminating the family during the late emperor's time.
Jin An is actually an orphan of the Yun family, and he plays the role of a stand-in, secretly investigating the family's grievances, and discovers that the regent is the real collaborator, and is also the mastermind behind the destruction of the Yun family and Lin Weiwei's death. Faced with each other day and night, Xie Zheng was attracted by Jin'an's sharpness and resilience, and fell into love and guilt; Jin'an was also shaken by hatred because of Xie Zheng's concern for the country.
When the time came, Jin'an drank a secret medicine and faked his death to escape. He went to the southern border to rise up using the brocade weaving method in the name of "Mrs. Jin" and secretly collected evidence of the regent's crime. Xie Zheng disguised himself as a tracer and discovered the truth: Lin Weiwei was an old member of the Yun family. He fell off a cliff and went into hibernation. From meeting, doting on his concubine, to faking his own death, everything was planned by Jin'an, and he was the "most deeply involved in the drama", and it was he who personally handed over the jade seal that destroyed the Yun family.
After Xie Zheng collapsed, he killed the regent to atone for his sins. He abandoned the throne and knelt down for three months to beg for forgiveness. He finally signed a marriage contract and changed his name to "Yun Zheng". He spent the rest of his life atonement to Jin'an and the Yun family. This relationship that started as a conspiracy ended with the emperor's complete surrender and the chess player's sincere acceptance.
