Episode 2 recap: Meng he Sheng was unexpectedly killed.

Song Ci said that the murderer was quite clever and couldn't figure out the whole situation at once. The next puzzles needed to be solved step by step. The first one was how the female ghost could run from the bow to the stern of the boat at the fastest speed and kill Mr. Tian, the local official. Lord Li initially wanted to take the two witnesses as suspects, but Song Ci stopped him and said that he didn't think they were the murderers.

Song Ci presented his own theory. If they were the real murderers and had killed someone and reported it to the authorities, why hadn't they obtained anything yet? They didn't have the treasure map. Lord Li had no choice but to let the two people go. First, they needed to figure out why the murderer opened all the cargo and scattered tea leaves on the ground. They suspected that there must be something hidden inside. Song Ci opened the box and indeed found Mr. Tian's head and a jade pendant. This jade pendant belonged to the concubine who eloped with Mr. Tian ten years ago.

Ten years ago, Yu Fuyao, a beautiful and young woman, quickly caught Mr. Tian's attention. As Yu Fuyao already had someone she liked, she refused to become Mr. Tian's concubine. Mr. Tian, in order to possess Yu Fuyao, even framed and tried to trap her to keep her by his side. Yu Fuyao was determined not to yield and committed suicide by jumping into the river the night she was preparing to clarify the situation.

To investigate further, Song Ci and his good friend Li Zifang sought out the all-knowing person to learn about Yu Fuyao's brother, Yu Gengyi. The all-knowing person was initially reluctant to take them to meet Yu Gengyi, as he had accompanied Mr. Tian to see Yu Fuyao back then. The intelligence of Yu Fuyao was also related to him, and Yu Gengyi always considered the all-knowing person his enemy.

Li Zifang explained their intentions, and Song Ci saw Yu Gengyi making a coffin and carving words for himself. Yu Gengyi said that the doctor had already told him that his life wouldn't last long. After learning about Mr. Tian's murder, his deceased sister could finally rest in peace. He had wanted revenge but lacked power and influence to kill Mr. Tian. Yu Gengyi was most angry at the all-knowing person and Meng He Shengfor bringing Mr. Tian to the village. If it weren't for them, his sister might still be alive.

Song Ci asked where he was on the night of the incident, but Yu Gengyi didn't give a direct answer. He only asked them to return his sister's jade pendant to him. Song Ci still believed that although Yu Gengyi had a motive for murder, seeking revenge ten years later seemed somewhat implausible. Even if Yu Gengyi wanted revenge, he should have had someone's help.

Li Zifang filtered through the list of names of all the people in Jiang Village, as the identity of the supposed beloved man of Yu Fuyao still remained unclear. Perhaps the murderer might be related to this man. Lord Li called Li Zifang and Song Ci over and mentioned that ten years ago, he was just a small county official.

On the way back, Song Ci was still analyzing Menghe's words. He wondered why Meng He Shengwould still set sail despite the heavy fog last night. Suddenly, Song Ci noticed a group of guards searching for the so-called female ghost. At that moment, Li Zifang informed Song Ci that the two prison guards, who were on night duty, had seen the female ghost again. This time, she had killed Qin Si, and there were several large characters left on the wall. Strangely, the body had even disappeared. The situation became even more mysterious.

Li Zifang discovered a strange leaf at the entrance of the prison cell. This type of leaf had never appeared in the city before. Li Zifang decided to temporarily sleep in Song Ci's room that night. Song Ci also informed Li Zifang of his suspicion regarding Menghe. Since Meng He Shenghad set sail on the night of the heavy fog, and considering Yu Gengyi's intense hatred towards Menghe, it was unlikely that anyone would think they were the ones responsible for the murders. Song Ci planned to go to the boat first to investigate.

Just then, they received a report from their subordinates that the female ghost had killed someone again. Song Ci hurriedly rushed out. They discovered another headless corpse, which had a striking resemblance to Mr. Tian. Witnesses had seen the female ghost appear on the lake when the heavy fog occurred. Song Ci suddenly noticed an injury on the victim's body, which he remembered seeing on Meng He Shengas well. Unexpectedly, the victim turned out to be Menghe, whom they initially suspected.

At that moment, Yu Gengyi appeared and claimed that Menghe's death was retribution. In order to solve the case quickly, Lord Li even brought Miss Shen Xiyue, from the Shen family, but Song Ci believed she was just a swindler and that they had to rely on themselves to find the real culprit. Li Zifang suspected that Qin Si's disappearance and Menghe's murder might not have happened at the same time.

Subsequently, the two of them arrived at the morgue. Song Ci decided to examine Mr. Tian's body first. They determined that the victim did not show any signs of poisoning, but they found silk on the body.
