Song Ci pointed out that the murderer's plan was not perfect, and the next mystery needed to be solved step by step.He first expressed doubts about the fact that the female ghost quickly ran from the bow to the stern and killed the stewards.Master Li initially wanted to take away the two witnesses as suspects, but was stopped by Song Ci, who believed that they were not the real murderers.

Song Ci put forward his own opinions.He believes that if the murderer actually kills someone and reports it to the police, they have not gotten anything and have gained nothing.Master Li had no choice but to release the two men.To solve this problem, they first need to understand why the killer opened all the goods and spilled the tea leaves all over the floor.They suspected there was something hidden in it.Song Ci opened the box and found Tian Yuanwai's head and a jade pendant.This jade pendant was the personal belongings of Yu Fuyao, a girl who disappeared while diving 10 years ago. She was the concubine of the field member who had never been outside the family.

10 years ago, Yu Fuyao was young and beautiful, and quickly attracted the attention of Tian Yuanwai.However, Yu Fuyao already has a sweetheart and refuses to obey and become a concubine outside Tian Yuan.In order to get Yu Fuyao, Tian Yuanwai even designed to frame her, trying to get her to stay with him.Yu Fuyao refused to obey, and on the night when he was about to clarify the facts, he jumped into the river and committed suicide.

In order to investigate the truth, Song Ci and his friend Li Zifang found Wan Shitong, hoping to understand the situation of Yu Fuyao's brother Yu Gengyi.Wan Shitong was initially unwilling to take them to see Yu Gengyi because he was the one who brought the field members to the village, which led to Yu Fuyao's tragedy.But Li Zifang explained his purpose, and they were able to meet Yu Gengyi.

Yu Gengyi was preparing a coffin and carving a tombstone for himself. He said that the doctor had told him that he would die soon.After knowing that Tian Yuanwai was killed, he thought that his sister could rest in peace.He wanted to take revenge, but he knew he was too powerless to kill officials.What he hates most is that the know-it-all Meng Hesheng brought field workers to the village, otherwise his sister might still be alive.

Song Ci asked him about his whereabouts on the night of the incident, but Yu Gengyi did not answer directly, but only asked them to return his sister's relic jade pendant.Song Ci believes that although Yu Gengyi has a motive, revenge ten years later does not seem logical.If Yu Gengyi wants revenge, someone should help him.Li Zifang screened the list of everyone in the village because there was another unidentified person - Yu Fuyao's lover - who might be related to the murderer.

Master Li called Li Zifang and Song Ci and said that ten years ago he was just a small county magistrate.Song Ci analyzed Meng Hesheng's words on the way back and didn't understand why he had to go out on the boat in the heavy fog last night.At this time, he saw a group of guards searching for the female ghost.At this time, Li Zifang told him that the two jailers saw the female ghost again during the night shift. This time the female ghost appeared and killed Qin Si, leaving several large characters on the wall.What's even more bizarre is that the body disappeared.

Li Zifang discovered a strange leaf that he had never seen before at the door of the prison.That night, he chose to spend the night in Song Ci's room.Song Ci revealed his suspicions about Meng Hesheng and believed that it was extremely unlikely that he and Yu Gengyi would cooperate in killing people on the boat on a foggy night.He decided to go to the ship himself to investigate.

At this time, the subordinates suddenly reported another incident of female ghost killing people.Song Ci quickly rushed to the scene.What was found this time was another headless body. The way of death was very similar to Tian Yuanwai.When the lake fogged up, some witnesses claimed to have seen a female ghost.Song Ci noticed a wound on the deceased's body, which matched the wound on Meng Hesheng's body.He was surprised to find that the deceased turned out to be Meng Hesheng whom they suspected.They originally thought Meng Hesheng was innocent.

At this time, Yu Gengyi appeared and claimed that Meng Hesheng's death was retribution.In order to solve the case quickly, Mr. Li even invited Shen Xiyue, the eldest daughter of the Shen family, to assist in the investigation.But Song Ci thinks she is just a charlatan and the real murderer needs to be found by herself.Li Zifang suggested that the time when Qin Si was taken away and Meng Hesheng was killed may be different.So the two went to the morgue, and Song Ci decided to check Tian Yuanwai's body again.He first ruled out the possibility of poisoning and found silk on the body of the deceased.
