Deep inside the palace, the 16-year-old new emperor Xiao Yun has just ascended to the throne. He has a pure nature but is ignorant of world affairs. He has no idea about the power of the court. He is a "silly and sweet" monarch in the eyes of everyone who needs support. Qin Heng, the eunuch and eunuch who grew up with him, was not castrated due to an accident in his early years. Although he was a eunuch, he was able to gain a foothold in the turbulent harem and the former dynasty with his resourcefulness and ruthless tactics.
Qin Heng was well aware of Xiao Yun's weaknesses. On the one hand, he shielded him from the wind and rain as a "confidant", helping him to resolve the pressure of the Queen Mother and the pressing pressure of powerful ministers, and even secretly eradicated the clan that coveted the throne. On the other hand, he used Xiao Yun's trust to quietly weave a network of power and draw back key forces such as the imperial army and spies for his own use.
Xiao Yun relied on Qin Heng wholeheartedly and regarded him as his only "relative", but he noticed something strange in the occasional clues - such as the silhouette of Qin Heng talking secretly with the courtiers late at night, or the jade pendant that did not belong to the eunuch accidentally exposed on his sleeves. While Qin Heng was taking control of the overall situation, he also gradually developed complex emotions towards this pure young emperor. He was both exploitative and intolerable.
When the Queen Mother teamed up with her old ministers to set up a scheme to depose the emperor and seize power, Qin Heng chose the most risky way: leading the troops as a "eunuch" to escort him, but at the critical moment of life and death, he exposed the secret of not being castrated. As the court was shaken, Xiao Yun finally saw the true nature of power and had to make a difficult choice between the wise eunuch who "betrayed" him and the shaky throne.
