Please recommend an ancient female killer novel. It has been completed.

The details were as follows: The female protagonist brought a subordinate to a villa and became the male protagonist's subordinate (a hall master). The male protagonist was forced to marry, the female protagonist secretly laughed and was framed by the male protagonist to become his wife (nominal husband and wife). At the wedding, a woman caused trouble. The female protagonist used a red silk ribbon to kill the woman, but was stopped by the male protagonist with tea leaves. At night, the female protagonist was sleepwalking while performing a sword dance, saying that she wanted to kill the adulterous couple. She was stopped by the male protagonist and was cut by the sword qi. The female protagonist and the male protagonist went to the martial arts tournament separately (and then forgot). In the middle, there was a paragraph saying that the male protagonist had a relative, a younger sister, who liked the male protagonist. The younger sister and the female protagonist were hit by a tornado or sandstorm at the same time? The male lead could only save one. The male lead wanted to save the female lead, but he saved his sister. In the middle of the story, there was a part where the female protagonist lost her memory, met a male supporting character, and was poisoned. She could only have sex with someone to detoxify the drug, but the poison would spread to the person who had sex. The male protagonist had sex with the female protagonist for the sake of the female protagonist. After the female protagonist found out about everything, in order to save the male protagonist, she used the male protagonist's villa to exchange for the antidote with the person who drugged her. The female protagonist was misunderstood and somehow traveled back to the modern world. Then, when the female lead was on a plane, the plane was hijacked by terrorists. After killing the terrorists, the female lead fell off the plane and traveled back to ancient times. Then, she had sex with the male lead.
