Wang Zhaoting and Liu Yuxi, among others, were invited to the Qin family's old mansion on Shui Jiao Island, with the promise of confidential information. During the journey, only Wang Zhaoting was questioned by a strange voice about their origins, while the others saw him suddenly faint. As they passed by an abandoned house, more and more strange occurrences unfolded. However, these were all orchestrated by Zhang Weiguo. It turned out that years ago, the Qin and Liu families, driven by profit, built mansions on the island, which led to the death of Zhang Weiguo's wife and child. This time, he lured them to the island to seek revenge. Wang Zhaoting was injured during the confrontation with Zhang Weiguo. In the end, the village chief allowed them to leave the island, and Wang Zhaoting and Liu Yuxi went to the local police station to report the incident. This case, spanning two generations, was finally resolved properly.
