The biggest highlight of the third suspense drama should be that it leaves readers/viewers with infinite space and clues to explore. As long as it is reasonable, you can doubt reasoning, which is also the advantage of this drama. My personal husband is Zhuang Yaobang, and the real murderer is Xu Zhengqing. In order to find Zhuang Yaobang and Luo Shen, he rented Zhuang's house and used Zhuang to attract Zhuang Yaobang and Luo Shen to appear.
Zhuang Yaobang also took advantage of this and let the suspect X appear. But the specific plot still depends on who the ghost is in the finale on May 20th. I hope the director doesn't have an open ending for us to guess.
