After He Yonglin's death, He Zhenwen gave Pei Yan an ultimatum. Pei Yan must exchange Jiang Ci's head for Rong Yudie's account books at Bihe Villa. Pei Yan was in a dilemma.
Jiang Ci begged Wei Zhao to return the little clay cat to her. She wanted to go to Yuzhou to find her master, but Wei Zhao flatly refused. Yueluo City is about to elect a new city lord. Uncle Ping, the elder of Yueluo, sent a message to Wei Zhao. Yi Fei notified Wei Zhao to return to Yueluo to participate in the election. Wei Zhao came to Nanling on the order of Emperor Xie Che of Liang Dynasty. It was not convenient for him to return to Yueluo. He If he wanted to report Lu Yu's secret weapons to the court, Emperor Liang would definitely send him to Chuzhou to investigate the matter thoroughly, and he would take the opportunity to return to Yueluo.
Wei Zhao heard that Pei Yan transferred He Zhenwen to the dungeon of Changfengwu. He went through the ins and outs of the ordnance case. He concluded that He Zhenwen had account books related to Lu Yu, so he sent Yi Fei to try to find these account books. Jiang Ci decided to leave to see Master the day after tomorrow, but she was worried that the person who came to join her was not Master. The little clay cat was their token of union, and Wei Zhao was reluctant to return the little clay cat to her. Jiang Ci suddenly had an idea and came up with a good idea. She pinched herself a little clay cat.
Rong Yudie sent Aunt Du to deliver a letter to Pei Yan, asking him to bury He Yonglin generously to appease He Zhenwen, and asked him to hand over the account books as soon as possible to avoid ruining their important event. Aunt Du brought Pei Yan to see He Zhenwen. Pei Yan accidentally discovered that there was a hidden arrow piercing the wound in He Yongli's hand. It was Wei Zhao who stabbed him to save Jiang Ci. Pei Yan remembered that the silver-faced assassin used this kind of hidden arrow. , so he decided that Wei Zhao was the silver-faced assassin. Unexpectedly, Jiang Ci had been hiding it from him, and Pei Yan immediately decided to send Wei Zhao back to Qingkang first.
Aunt Du sent someone to assassinate Jiang Ci. Pei Yan arrived in time to knock Jiang Ci unconscious, then took her back to Changfengwu and warned Mrs. Du not to harm Jiang Ci. Wei Zhao learned that Pei Yan had brought Jiang Ci to Changfengwu, and he rushed to Changfengwu overnight. Jiang Ci woke up in a daze and saw Pei Yan beside her. She guessed that Pei Yan had knocked her out. Pei Yan didn't want to explain too much and persuaded her to stay in Changfengwu with peace of mind. Then they went back to Qingkang together. Jiang Ci Ci was determined not to do it and stood up to leave. Pei Yan stopped her and Jiang Ci broke away from his arms and left Changfengwu forcibly.
Wei Zhao arrived just in time, and he took Jiang Ci away with him. Pei Yan looked at their backs with mixed feelings in his heart. Jiang Ci and Wei Zhao said goodbye, preparing to leave to meet their master tomorrow. Pei Yan came to see Wei Zhao early in the morning, and the two agreed to return to Qingkang together tomorrow. Yi Fei guessed that Wei Zhao wanted to cover Jiang Ci's departure, and Cui Liang came to see Jiang Ci off. He casually mentioned that Pei Yan wanted to return to Qingkang in three days, but Wei Zhao insisted on leaving tomorrow. Cui Liang also saw Wei Zhao's intention, and he agreed to escort Jiang Ci out of Nanling.
That night, Jiang Ci secretly left without warning. Cui Liang had been waiting for a long time, and the two of them left Nanling in a carriage. Wei Zhao had been secretly protecting Jiang Ci and Cui Liang. He put the little clay cat in the carriage. Jiang Ci saw the little clay cat and was grateful to Wei Zhao. Cui Liang accidentally revealed that Pei Yan found out that the wound on He Yonglin's hand was caused by a silver-faced assassin. Jiang Ci's heart skipped a beat. Once Pei Yan knew that Wei Zhao was a silver-faced assassin, Wei Zhao's life was in danger, so Jiang Ci decided to stay. .
Cui Liang sent Jiang Ci outside Nanling City, and then drove the carriage back. Jiang Ci saw Cui Liang walking away, so she rode back to Changfengwu. Seeing Pei Yan packing her things, Jiang Ci decided to take Pei Yan away first. Yan leads away. Pei Yan packed his luggage and was about to leave. When he found that Jiang Ci was missing, he immediately rode on horseback to chase him. Jiang Ci took advantage of the chaos and threw a handful of pollen, which made the horse go crazy. Jiang Ci took advantage of the chaos and took away the hidden arrows collected by Pei Yan.
Jiang Ci returned the hidden arrow to Wei Zhao and reminded him not to return to Qingkang. Pei Yan found out through the hidden arrow that Wei Zhao was the silver-faced assassin. Pei Yan chased Jiang Ci to the outside of the city in one breath, but there was no sign of Jiang Ci. He immediately returned and found that the small box containing the hidden arrows was missing. He guessed that Wei Zhao had stolen it, so he came directly to Wei Zhao to question the crime. Wei Zhao took Jiang Ci to task. Ci hid in the cabinet, and Jiang Ci begged Wei Zhao not to let Pei Yan take her away.
Wei Zhao came out to see Pei Yan, and Pei Yan urged him to get on the road as soon as possible. Wei Zhao lied that he had a stomachache and wanted to postpone for a few days. Pei Yan decided to go with him and even took Wei Zhao to drink together. Wei Zhao had to invite him into the room. . Pei Yan and Wei Zhao exchanged cups, while Jiang Ci hid in the cabinet and felt uneasy. Pei Yan already knew Wei Zhao's true identity and tested him in every possible way. Wei Zhao responded calmly without being humble or arrogant. Pei Yan did not find any flaws. He suspected that Jiang Ci was hiding under Wei Zhao's bed and in the bathtub. Wei Zhao took him to search for him personally. Pei Yan Just as he was about to open the closet, Wei Zhao revealed to his face that Pei Yan had covered up the truth about the arms case, and he drew his sword and stabbed the closet to confirm that there was no one hiding in the closet.
