Long Wanyu, the queen of Dayao Dynasty, hides an IQ and calculation that is not inferior to that of men under her dignified and restrained appearance. After entering the palace for three years, she sat firmly in the middle palace as a queen, but she was trapped in the turbulent whirlpool of the harem - concubines competing for favor, relatives plotting against each other, imperial power being tested, and murderous intent everywhere. She has no sharp claws or sharp blades, but she can hide her sharp edge with a pair of loving eyes, use her gentle tone of voice to lay traps, draw the bottom line with thorough etiquette, and rely on subtle sarcasm to hit the point directly. Without spending a single blow, she will make those who covet the position and scheme against her lose every step of the way. Her golden finger is a photographic memory and an accurate prediction of people's hearts. She can catch flaws from the smallest details and play with people's hearts. In the harem, some people go crazy for favor, and some sink for power, but Long Wanyu has always been sober and self-possessed, using scheming as armor and strategy as blade. Within the palace walls with surging undercurrents, she protects herself and her family's honor and disgrace while dealing with villains who are tempted by power. Step by step, she finally becomes the real ruler of the harem and lives a legend that no one can match.
