Upon seeing the three unconscious barbarians before him, Prefect Jin was astonished. He hadn't expected that there were actually barbarians in Yuanxi City, and that he had captured three of them.

He was starting to wonder if they had arrested the wrong people. These people looked no different from the locals, so why was Zhao Cheng so sure they were from a foreign country?

Not only did Prefect Jin think so, but the others were also a little puzzled. They looked at Zhao Cheng, wondering what his basis was for concluding that these three people were from a foreign country.

"Because I have lived in foreign countries for many years, I am very familiar with the customs of foreign people. When we were having dinner at the restaurant just now, my intuition told me that they were foreign people."

The foreign lands are located in the northwest, and they eat with their hands. The people there don't know how to use chopsticks at all. Even if they infiltrate our Great Northern Dynasty, they can change everything, but they can't change this one thing.

Today at the restaurant, these three people ordered quite a few dishes, mostly hand-pulled meat, which is consistent with the dietary characteristics of foreigners. To prove my deduction, they disguised themselves as impoverished swordsmen and went to the restaurant to sell their swords.

Foreigners are greedy to the core; they want to possess anything good they see. Sure enough, they fell for my trick and followed me out of the restaurant.

Then they pretended to want to buy my sword, took me to a secluded place, and prepared to kill me and steal it.

At this point, their true colors were revealed. Through conversation, it was confirmed that they were indeed foreigners. So I stopped being polite and subdued them all.

However, asking any questions is a bit difficult. The true foreigners would rather commit suicide than reveal their secrets; otherwise, the foreign country wouldn't have sent them here in the first place.
