The girl Wu Wenxuan was originally an orphan. Her adoptive parents adopted her family as their own daughter, but soon her adoptive mother became pregnant and gave birth to a boy. This family can no longer tolerate Wu Wenxuan. She was abused in this family, and Wu Wenxuan, who couldn't bear it, chose to kill their family, and then pretended to be killed by the Baisha Luo couple. Follow-up story:

Because of this case, Wu Wenxuan got to know Lu Li. After investigation by the police, it was found that the murderer Bai Shiluo and his wife were killed. The senior section chief of the clinical laboratory has been struggling with why there are carrots in Sichuan-style pork, and finally found that the food was tampered with, but because Lu Li married Wu Wenxuan, the matter went away.

Six years later, President Lin of Huacheng Health School was killed. After investigation, Chi Zhen and Lu Li found that this matter was related to Wu Wenxuan, and a test paper six years ago made Wu Wenxuan's alibi untenable. Later, nurse Zhang Xinling and her neighbor Aunt Zhao were also killed. Wu Wen chose the present crime scene and became the biggest suspect. After attending President Lin's funeral, he voluntarily surrendered to the Criminal Investigation Bureau.
