Yang Sangu is a poor, hateful and pathetic person. She has been a child bride in the Wangs since she was a child. Later, when the son of the Wangs died, the king took it out on her, saying that she had killed him, scolded her, and later sold her to the nephew Tu of the Queen Mother's family. Tu knew that Yang Sangu had a hard time in the Wang family, so he gave her all kinds of favors when he married the Tu family. Of course, Yang Sangu is also very beautiful, so their married life was fairly happy at first, but a man named Feng saw Yang Sangu grow so beautiful that he provoked her intentionally or unintentionally. After a long time, Yang Sangu also moved his heart, so he often used an excuse to go back to his parents' house. Later, a month later, when Mutu saw that his daughter-in-law had not come home, he asked Tu Rusong to call her back. But when he went to Yang Sangu's house, he realized that Yang Sangu didn't come home. At this time, Yang Sangu's younger brother and Tu Rusong began to worry, and they all went to report to the officials.
Yang Sangu's younger brother, Yang, was stopped by Zhao Wei on the way to report the case, persuading him that he had killed his sister, so Yang took him to report the case and insisted that his brother-in-law had killed his sister. Fortunately, the local judge is a good official. After receiving their report, he began a detailed investigation, which led to another case. The owner of this case is Yang. Although this man is good-looking and ugly, he is still a patriarch, so he is young and promising. The reason why he was found on his head was because he also had an ambiguous relationship with Yang Sangu, so the Tang magistrate removed Yang from the position of patriarch, but there was still no progress about Yang Sangu's disappearance.
A year later, a man's body was salvaged in a place called Jiukoutang. (This man's body is probably Feng. When Yang and Yang heard this, they had to say that it was Yang Sangu's body and accused the Tang magistrate of shielding Tu. The incident became more and more serious, and was later known by the governor, so he sent Gao to investigate the matter. When Yang and Yang learned about it, they were overjoyed and immediately borrowed money to eliminate the disaster. Unexpectedly, the new official really took their money and reported to the superior that the body salvaged from Jiukoutang was a female body, implying that it was killed. He also said that the county magistrate ordered Tang to accept bribes, so Tu was arrested and tortured him in prison.
Tu Rusong couldn't stand this inhuman torture, and finally he could only admit the fact of killing his wife. But the body really doesn't belong to Yang Sangu, so this Ren-Gao Jie insisted on Tu to find the woman's body in order to make more evidence, so the poor Tu almost searched the whole county grave and couldn't find a suitable person. In the end, there was no choice but to cut off her hair as evidence. The wife of the Tang magistrate had to dig up her daughter's grave and take out her toe bone for Ren.
But heaven has eyes, a rainstorm flooded the whole county, so the nameless body was washed away, and the case could not be settled, so it was delayed for another year. Later, Yang's wife gave birth to a child and invited a midwife to deliver the baby. This Yang's wife was in such pain that she quickly called her third aunt for help. At this moment, a woman ran out of the dark room. This woman is Yang Sangu who has been missing for three years. The midwife was surprised, but she showed no panic. After giving birth, she went to report the case. Fortunately, the new magistrate of a county is a good official and has been thoroughly investigating this matter. When he learned of this situation, he immediately took people to Yang's house and arrested Yang Sangu, who was hiding in a dark room, so the matter really came to the bottom, and Tu and Tang Magistrate were exonerated and fair. Of course, this matter can actually spread and is also related to Yongzheng. Because he had already heard about it, he sent Shi Yizhi to investigate the matter and learned that it was related to the new magistrate of a county.
