**——She used Fengyue as a chess game to plan a world-wide chess game——**
**Yu Qingxian**, the famous Zuixianlou oiran in the capital, dressed in plain clothes and played the piano, amazed everyone with her song "Nine Heavenly Phoenixes". The world only knows that she has stunning looks and unparalleled talents, but they don't know that she is also the leader of the mysterious organization "Ye Tan" in the world, with superb medical and poison skills and unfathomable martial arts. Fifteen years ago, she was the youngest daughter of General Yu Hong, who witnessed the massacre of her whole family. The blood feud was unforgettable. Now, she is sleeping in a brothel in the name of an oiran, just to find out the truth about the family's extermination and kill her enemies with her own hands!
**Ni Yunzhou**, the youngest Prince Jing of the Zhou Dynasty, had great military exploits, but his life was hanging by a thread because of the "cold marrow poison" in his body. Following the order of the late emperor, he secretly investigated the Yu family's unjust case, but when he first met Yu Qingxian in Zuixian Tower, she discovered the strange poison in her body at a glance. She crossed the acupuncture point with a silver needle, and he pointed at the court with his sword. From testing to joining forces, the two of them approached the truth step by step.
**——In machinations and love and hate, who is in the game? ——**
When the oiran's dancing sleeves hide his edge, when the prince's chess game hides his kills, a storm is quietly brewing that sweeps the government and the public. The secret letter of treason from the Zhao family, the Nine-Dragon Jade Pendant left by the late emperor, the flash of swords and shadows at the brothel night banquet... Yu Qingxian maneuvered among the powerful with a peerless manner, and Ni Yunzhou was willing to block the open and secret arrows for her.
**"My lord, do you know that if you cooperate with me, you are seeking the skin of a tiger?"** She chuckled, the silver needles on her fingertips gleaming coldly.
**"If the tiger were you, Ni would be willing to feed it."** He took her hand and put half of the jade pendant into her palm.
