Interpol Chu Nanzhi traveled to the last years of the Dahe Empire, and became a wicked woman hated by thousands of miles and eight villages and a vicious mother of four little ones.

But on the first day after transmigrating, she encountered a catastrophe of extermination. She used her past life director to help the original owner’s husband get rid of the crime, and saved herself and the four little ones.

Back home, Lin Jinxiao and the four little ones still hated her and were always wary of her.

Looking at Lin Jinxiao and the four little ones who were sick in bed, Chu Nanzhi didn’t want to give up the truth, and decided to wait until Lin Jinxiao recovered from his injury, reconcile with him, and promised to take care of the little ones temporarily.

Because of being highly valued by the county magistrate and wealthy households, Chu Nanzhi took advantage of this time to become a proficient detective and supported her family by investigating cases. She assisted the county magistrate in solving many cases and gradually changed the attitude of her neighbors towards her.

Later, Chu Nanzhi proposed to make peace with Lin Jinxiao, but the four little ones refused at first.

She went out to handle a case, and the four little ones were afraid that she would never return, so they chased after her: “Mother, we want to go with you,”

When she came to Beijing to meet her, the county magistrate took her hand and refused to let go: “You are already the mother of four children.”

One day, when Lin Jinxiao became the emperor, he put his arms around Chu Nanzhi and said, “You have been trying the case for so many years, so stay in the palace and try it on me, I have grievances!”
