Episode 19 recap: Song Ci unravels the secrets at Yin Family Village.

As Song Ci pondered over who the murderer could be, considering that the crime scenes of the two locked-room murders were identical, she discreetly mentioned a person's name to Li Zi Fang, who was surprised. When Yin Qiao returned, Song Ci informed him that she wanted to go back with him because the killer had likely completed their mission and would soon choose to leave. Therefore, they had to seize the opportunity and rush over.

On the other side, Shen Xi Yue also hypnotized Yin Xin in hopes of discovering the truth, and they soon learned some secrets. These pieces of information were crucial for them. Yin Xin, through her recollections, discovered that the masked person had killed her mother. When Song Ci and the others returned, Yin Qiao's mother was extremely surprised, even a bit reluctant.

Subsequently, Song Ci also informed Yin Chao that Ye Zhi Fang was actually Yin Lan, and she was now deceased. Surprisingly, it was the mother who vehemently tried to conceal this fact. In reality, there were three main players in this incident: Chen Yi, Yin Chao, and Yin Lan. Naturally, the mother refused to believe it, and Yin Qiao was also very surprised. Song Ci also revealed that not all members of the Ye family were killed back then. The records stated that thirteen people were killed, but there were only ten ancestral tablets. Shen Xi Yue also deduced that Yin Chao and Yin Lan were actually siblings from the Ye family. Seeing the pitiful condition of the children, the head of the Yin family didn't kill them but instead took Yin Chao back to raise him as an act of redemption towards the Ye family.

By a stroke of fate, Chen Yi also encountered Yin Lan and they recognized each other, vowing to avenge their parents. Yin Chao wanted to leave but was surrounded by soldiers. The so-called chance encounter with a beautiful woman was intentionally fabricated by them, and everything that happened in the wooden house was deliberately arranged by Yin Lan. Shen Xi Yue had checked and found no traces of monsters. Together with everyone else, they pretended to discover Ye Zhi Yuan's tombstone, making everything appear haunted.

The white fox seen by the maid was also deliberately sent in. The so-called Taoist priest was arranged by Chen Yi to make the whole affair seem more ghostly.

The death of Lai Fu was also carefully planned by them. Chen Yi had already noticed the poor relationship between Lai Fu and the maid. On the night of the crime, Chen Yi claimed he went to buy medicine, but an investigation by Li Zi Fang revealed that he did not actually purchase any medicine that night.

Chen Yi and Yin Xin are actually siblings. They are both children of the second uncle. Back then, only the second uncle refused to get involved in this matter. The claim made by the head of the Yin family that Yin Xin's mother committed suicide by jumping into a well was false, and the truth was what Yin Xin stated. Initially, Song Ci didn't suspect Chen Yi. She only discovered that the second uncle was not killed that night but had his clothes opened. She wanted to confirm if the second uncle was her father.

As for Lai Fu's death, Yin Chao didn't actually give him medicine that night. He deliberately called Lai Fu into the room and drugged him, then placed him on the bed. Finally, Lai Fu died from a rod inserted into his anus, and it would be difficult for an ordinary person to detect any flaws. Chen Yi wanted to defend himself, but Song Ci provided a reasonable explanation. The room was not actually locked, and the real locked room was Lang Zhengcai's room. Lang Zhengcai was indeed drugged and killed by Yin Lan. Yin Lan originally intended to pretend to be injured, but accidentally stabbed her leg's major artery, resulting in excessive blood loss and her death.

The soldiers ordered the capture of Yin Chao. Yin Chao was grateful for Yin Qiao's mother's care over the years and felt that he had finally avenged his family. Yin Chao deliberately drew his sword, and the soldiers immediately killed him. Chen Yi initially wanted to resist but was immediately subdued by the soldiers. Chen Yi could only apologize to Yin Qiao. The case was finally solved.

Li Zi Fang knew that Yin Qiao was feeling upset, so she approached her to offer comfort. Yin Qiao didn't expect the outcome of the case to be like this. Li Zi Fang asked Yin Qiao if she was willing to leave with her. Yin Qiao thought that after her father left, she still had her brother, but now her brother was gone too.

Now the whole estate can only rely on Yin Qiao, so she won't leave temporarily. Song Ci also expressed her gratitude to Shen Xi Yue and Bai Xue Yan. Thanks to their efforts, the case was successfully solved.
