Wei Zhao was worried that An Cheng would reveal his secret to Pei Yan, so he tried to hold An Cheng back while making a private appointment with Jiang Ci.In an alley, the two reached a tacit agreement. Jiang Ci promised to keep the secret that Wei Zhao was a silver-faced assassin, just to get her little clay cat back.Later, they returned to the market together, only to find An Cheng following closely behind them.In order to prevent Pei Yan from misunderstanding about the relationship between the two, Wei Zhao deliberately made Jiang Ci fall down, causing confusion, and he took the opportunity to leave.
Jiang Ci and An Cheng returned to Jian Dinghou Mansion. Pei Yan asked with concern about Jiang Ci's fall, while Jiang Ci was eager to share important clues gained from visiting Tong Min and Fan Yi in prison.She noticed that Fan Yi was extremely sensitive to the word "behind the house" and mentioned the assassin sneaking into the Villa, guessing that Fan Yi had something to hide.
Early the next morning, Pei Yan summoned Wei Zhao to the river to discuss the hypothesis that the murderer might have used a secret passage in the water to enter the Villa.After careful investigation, they found Bie Yunjin's silk thread near the culvert. This kind of silk thread has recently been sold to Weiguo in large quantities.Combined with Cui Liang's investigation, Pei Yan suspected that a master who had a grudge between Wei Guoyou and Teng Rui was involved in the case.An Cheng further speculated that the fire in the Bieyuan was caused by internal strife in the Wei Dynasty, and implored Pei Yan to report it to Emperor Xie Che in order to rescue Tong Min, but Pei Yan was hesitant.
Wei Zhao made a clever plan to lead the suspicion to the Wei people, and persuaded An Cheng and Cui Liang to stay away temporarily and let Pei Yan think alone.Jiang Ci saw through Wei Zhao's plan, accused him of deliberately misleading Pei Yan, and suspected that Wei Zhao was Xiao Wuxia, but suffered from the lack of conclusive evidence.
Jiang Ci recalled everything that happened on the day of the birthday banquet and realized that Wei Zhao's every step was carefully planned to clear the suspicion of the Yueluo City clan members.Although she felt pity, she was also determined to reveal the truth.With the help of Cui Liang, Jiang Ci learned about the tragic history of Yueluo City and became more sympathetic to Wei Zhao's situation.
In the dead of night, Jiang Ci could not sleep. She discovered that there might be a hidden reason for Teng Rui's death and suspected that Teng Rui was not really dead.In order to prevent Pei Yan from falling into danger, she decided to investigate alone.After some hard work, she found something suspicious about Teng Rui's body and confirmed that the body was not Teng Rui's own.
When Pei Yan entered the palace to resume his life, Jiang Ci caught up with him and presented his findings.Pei Yan and Jiang Ci immediately returned to the Hou Mansion. Wei Zhao saw this scene and was secretly wary.Cui Liang requested an autopsy, and Pei Yan applied to Emperor Da Ming for permission.In order to prevent the truth from being revealed, Wei Zhao acted quickly and instigated Lao He to expose Teng Rui's crimes and lead the finger to the Weiguo assassin.
After receiving Xie Che's authorization, Pei Yan secretly searched for Teng Rui's whereabouts.At the same time, Jiang Ci and Pei Yan encountered a mutton noodle stall owner who was grateful to Pei Yan while investigating in the city. This scene deepened Jiang Ci's respect for Pei Yan.On the other side, An Cheng discovered Teng Rui's trace and tracked it to the Lu family of Zhenyuan General. Pei Yan realized that this might be a plan to divert the tiger away from the mountain, and decided to act cautiously and report to Xie Che.
