The general trend of the world, the decline of imperial power, and the four great clans co-ruling the world, turned the harem into a miniature sandbox for the interests of the previous dynasty to strangle. Su Qingyue, a female liar from thousands of folk families, was forcibly kidnapped by the declining Su family of Jiangzuo and married into the palace in place of her legitimate daughter Su Qingyao, who had escaped from marriage.

In the palace, the suspicious and crazy emperor Xiao Changji, the sinister and powerful minister Wang Lang, and the aloof Qingliu Taifu Pei Yan are all man-eating wolves.
In a desperate situation, Su Qingyue awakened the "palace sand table deduction" golden finger. Every night when she goes to sleep, she can import the palace information from the day into the dream sandbox, and conduct countless zero-cost trial and error deductions about the upcoming poisoning, frame-up, and sleeping arrangements. Relying on god-level acting skills and the absolute error-tolerance rate of the sandbox, she disguised herself as a sickly, pure and kind-hearted white moonlight, and shuttled through the Shura field of all forces with ease, turning fatal crises into a ladder to the top.
As the emperor's secret plan to reduce vassal status broke out, murders in the harem occurred frequently. Su Qingyue used herself as bait and used the butterfly effect caused by the sand table deduction to perform a series of counterintuitive tactics, causing the four gatekeepers to bite each other. Her lies snowballed. From a harem chess piece that could be discarded at any time, she worked step by step to secretly seize the financial power of the inner treasury and the military power of the capital. When her multiple disguises were completely torn apart and her true identity was exposed in the court, the former high-ranking bosses drew their swords against each other...
