Later, Pan Yue saw Jishan Hall purchasing double copies before passing.The clothing list revealed that the employment in front of them was fake, so the two were surrounded.Seeing this situation, Pan Yue and Zhuo Lanjiang revealed each other's identities, so they saw the real hire.

Pan Yue saw the blood sword through Gu Yong, and then learned that Gu Yong had broken his hand tendon more than ten years ago and stopped using the sword. The only son who knew the blood sword, Gu Shan, had died five years ago.

Afterwards, Gu Yong stopped Pan Yue who was about to leave and pointed his sword at Pan Yue, but was blocked by Zhuo Lanjiang.When Pan Yue left, he met the crazy Mrs. Gu and heard Mrs. Gu say that Gu Yong was the murderer. Later, he learned that Mrs. Gu went crazy because of Gu Shan's death.

After returning to the county government, Pan Yue determined that the murderer killed with his right hand and Gu Yong's right hand was disabled, so he believed that Gu Yong was not the murderer.
