Chang Si gave the money from the salt sale to housekeeper Wang Tiangui, but there was still a lot of silver left.Li Laizi and Wang Tiangui, who were in charge of the Yingwaihe family, wanted to seize the opportunity to let Chang Si use the house to pay off the debt. Gu Pingyuan seized on the logical loopholes in the contract and pointed out that there was still one day left to repay the debt, and then drove them away.In order to help Chang Si find a way to repay the money, Gu Pingyuan decided to go to the streets to find a way, and Chang Yuer followed.

They happened to meet the Mongolian businessman Hanlong and his cavalry who appeared in a high-profile manner and informed Horqin that there was a horse plague and the prince wanted to ask the cavalry to deliver medicine. Gu Pingyuan told Chang Yu'er that this was an opportunity to solve the Chang family's current predicament.Gu Pingyuan and Chang Yuer arrived at the inn where Hanlong was staying and learned that the money for this delivery could fully repay Wang Tiangui's debt. Although the journey was difficult and the time was tight, Gu Pingyuan accepted the order in the name of Chang Si and persuaded Hanlong to get part of the fee in advance to repay Wang Tiangui's debt.
The keen Wang Tiangui vaguely felt that Gu Pingyuan was not a simple person, so he immediately asked the housekeeper to find a portrait to find out Gu Pingyuan's identity. The housekeeper quickly found out Gu Pingyuan's true identity.Due to bad weather and poor road conditions, the convoy struggled to move forward in the snow. The large team was preparing to enter the most dangerous black water swamp before dark.On the other side, Li Qin heard that Su Zixuan was going to join forces with Li Wantang to open a pawn shop and a bank account in Shanxi, and told his father that he was going to Shanxi with Su Zixuan. Li Wantang's dissuasion was useless, but instead aroused Li Qin's inner dissatisfaction and grievance.
