He Yunxing and Yue Yao found a strange mask. After rubbing the inner outline of the mask, they found that the person who wore the mask must be the crazy concubine Qiao Niang in the mansion.The two went to ask Qiao Niang for questioning. Unexpectedly, Qiao Niang lost control of her emotions when she saw Yue Yao and stabbed Yue Yao with scissors. He Yunxing rescued Yue Yao and was stabbed by the scissors on her palm.
Yueyao helped He Yunxing bandage his wounds, and prompted by the blood stains on the bandages, he discovered that the blood stains on the bloody clothes left at the crime scene were actually the bloody palm prints of the deceased.So He Yunxing went to Qiao Niang alone with the blood clothes to interrogate, and the interrogation revealed that it was indeed Qiao Niang who killed the person. It turned out that Qiao Niang was violated by the deceased, and she accidentally injured the deceased in a panic to protect herself.However, Yueyao discovered clues when reconstructing the incident.
