On the day when Xie Wan Yin, a noblewoman of the Xie family, married Prince Li Chi, she unexpectedly witnessed a cruel hunt: Dongfang Zui, the legendary elegant and extraordinary national teacher, shot and killed the father-in-law of the current emperor with a smile. Xie Wan Yin thus became the prey of the national teacher. Sure enough, under the conspiracy of Dongfang Zui, the wedding of Xie Wan Yin and the prince changed dramatically, but to Xie Wan Yin's surprise, Dongfang Zui did not want to kill her to silence her - but threatened the entire Xie family to force Xie Wan Yin to become the wife of the national teacher. It is said that the national teacher is dressed in white and bright, but only Xie Wan Yin knows that he is a cruel, cruel, and extremely vicious madman. Xie Wan Yin, who would rather die than surrender and is resolute by nature, resolutely decided to kill this madman. On the wedding night, Xie Wan Yin had been planning for a long time and was determined to take action. Unexpectedly, Dongfang Zui looked at Xie Wan Yin holding a dagger with a smile, and actually held her hand tightly, and took her to stab the tip of the knife into his heart. "Madam, if you want to kill me, just tell me. There's no need to go through so much trouble." From then on, Xie Wan Yin began to compete with her husband, the imperial teacher, in a battle of wits and courage. But gradually, she discovered that Dongfang Zui was quite similar to an old friend from her childhood, and a long-standing conspiracy involving two generations began to reveal its fangs behind the two of them slowly.
