Pei Yan, Wei Zhao, Cui Liang and Jiang Ci rode a carriage to Nanling. On the way, Jiang Ci shared carefully prepared cakes, while Yi Fei and Tong Min rode with them on horseback, quickly establishing a deep friendship.After arriving in Nanling, the group changed to a small boat. Although the scenery of Nanling along the way was beautiful, Pei Yan and Wei Zhao had no time to care about it and focused on discussing the ordnance case.Jiang Ci was happy to help the fisherman girl Ayan punt the boat and generously took off her clothes and gave them to her.

After a long journey, everyone finally arrived at Changfengwu, the ancestral home of the Pei family.When Ayan returned the cloak, Jiang Ci gave it to her again to keep out the cold.After Pei Yan returned home, he held a banquet to entertain his clan members. However, Pei Zifang, the leader of the Pei clan, was quite contemptuous of Pei Yan and spoke harshly. He even accused Pei Yan of bringing shame to the Pei family because of his affair.Jiang Ci was worried that Pei Yan's face would be damaged and wanted to avoid the banquet. Fortunately, Wei Zhao stepped forward to defend Pei Yan, which made the tribesmen panic and apologize.Although Pei Zifang knew that Wei Zhao was a prominent figure, he still could not escape severe rebuke.

After the banquet, Jiang Ci quietly acted and mixed the cold Clivia into the porridge, and specifically told Pei Yan not to eat it, in order to teach Pei Zifang and others a lesson.Later, she and Cui Liang went out to relax, while Wei Zhao secretly observed from the side.

The next day, Cui Liang accompanied Jiang Ci on a street tour. Cui Liang recalled an adventure half a month ago due to a purse, when a thousand paper cranes arrived carrying poems.Jiang Ci ran into Wei Zhao at a porridge stall and asked him why he was traveling with him, but to no avail, he found out that Wei Zhao was addicted to sugar.Wei Zhao asked Jiang Ci to help crack the code book of Changfeng Wei's secret letter. After being rejected, he revealed that there were strange flowers in Yueluo City that could make the porridge less bitter, but Jiang Ci accidentally discovered that the porridge and rice were Chen.

Pei Zifang and his tribe suffered from diarrhea due to eating porridge. Pei Yan suspected something fishy and ordered Tong Min to investigate.Wei Zhao and Jiang Ci returned home, and Cui Liang also arrived to show off their new purse.Pei Yan welcomed Jiang Ci and gave him a cloak. Wei Zhao became jealous when he saw this.

Pei Yan realized that Wei Zhao was really here for surveillance, and asked Jiang Ci to help him act, and Jiang Ci agreed.Wei Zhao was furious when he learned that Jiang Ci was staying at Pei Yan's place, and ordered Yifei to continue tracing the whereabouts of sisters Yan Qiaoshuang.At the same time, Pei Zifang colluded with He Zhenwen, the governor of Nanling, to resell ordnance, resulting in a lack of armaments.He Zhenwen had no choice but to cut corners and cut materials for emergency response, but he did not expect that this batch of inferior ordnance would be delivered to Qingkang.Pei Zifang urged He Zhenwen to deal with the aftermath quickly to avoid being investigated.

Pei Yan and Wei Zhao went to the Governor's Office and the Foundry Department to investigate. He Zhenwen used the fire as an excuse to cover up mismanagement, but Wei Zhao saw through his lies at a glance.Although no direct evidence was found, Wei Zhao proposed to conduct an in-depth investigation secretly in the name of fun.

On the other hand, He Zhenwen's son He Yonglin was indignant at what happened to his father. He Zhenwen warned him to avoid conflicts with the Pei family and conspired to hide evidence in response to the upcoming inspection.
