Sima Junru led a group of imperial guards into Yancheng, on the border between the Song and Jin dynasties.

Yancheng was a border trading city established by the Song Dynasty after the establishment of trade relations between the Song and Jin Dynasties.

All goods flowing into the Jin Kingdom must pass through here.

There were special government offices to inspect the goods.

On this day, Wanyan Hong, a nobleman of the Jin Dynasty, personally led his caravan into Yancheng.

They shipped large quantities of mink and deer pelts, as well as wine brewed by the Jin dynasty itself.

As soon as they entered the city, they were surrounded by the Imperial Guards.

Wanyan Hongdao said, "Sir, what do you mean by this? We are legitimate merchants."

Sima Junru smiled and said, "Don't be nervous, we're just doing a routine check."

Wanyan Hong's expression softened slightly.

Several Imperial Guards began their inspection, their actions were extremely rough.

"Reporting to my superior, we have discovered contraband."

Upon hearing this, Wanyan Hong immediately became anxious: "This is mink fur, how is it prohibited?"

Wanyan Hong remembered it clearly: for the past few years, he had been doing mink fur business with the Song Dynasty, but he had never said anything about it being illegal.

Sima Junru smiled brightly and radiantly: "According to the latest commercial law of the Great Song Dynasty, this is prohibited. These are all prohibited."

Wanyan Hong's face darkened: "This is impossible! I'm going to the Ministry of Commerce and Finance to sue you!"

"The Ministry of Commerce and Industry is an official department of our Great Song Dynasty, and it only deals with the affairs of our Great Song Dynasty. You are a citizen of the Jin Dynasty."

"However, the Song Dynasty and the Jin Dynasty are now engaged in equal trade, and everyone must abide by the rules. The Commerce and Trade Bureau must protect my basic rights."

Sima Junru smiled even more slyly: "That's strange. Since it's equal trade and everyone abides by the rules, why doesn't your country abide by the patent law of our Great Song Dynasty and instead steal the blueprints for Huaxing spinning wheels?"

"this……"

Wanyan Hong was speechless for a moment, but then immediately realized that this was a conspiracy deliberately targeting him.
