Hu Mo, a modern sinister man who traveled to the world of palace fighting, was forced to become a eunuch in charge of the cold palace. He wanted to live a peaceful life, but he accidentally got involved in a harem fight. When the gloomy and sinister man met the arrogant and domineering concubine Shen Qianqian, his style began to go astray - she poisoned people, and he secretly switched to laxatives; she framed her, and he dug a hole to make her jump; she cried and complained, and he talked nonsense seriously. The two went from being dissatisfied with each other to teaming up to trick everyone in the Sixth Palace, turning the serious palace fight into a comedy game. But when the real villain, the Queen Mother, appears in person, the farce instantly turns into a life-or-death situation. Hu Mo's golden finger "mind-reading skill" sometimes fails to work, and Shen Qianqian's "domineering concubine" persona is about to collapse. How can they survive with a smile in a deep palace that eats people without spitting out their bones?
