"The Ziliujin black market has three sources," said Chang Geng. "The first is from the officials' storage. Although the regulation is strict, there are always rats who are willing to take risks for profit. They steal from the officials’ stock, mix in various impurities, then spread them out. The second is from the 'black gold merchants', these are those who are desperate enough to travel outside the country to look for a Ziliujin mine, risking their lives to dig it up; the third is from overseas, the reason why we came to check this line especially is because the ultimate source of Ziliujin is from the Southern Sea."

Gu Yun sat up straight: "Are you sure?"

Chang Geng nodded silently.

Shen Yi's expression had also become grave.

They all knew that the Southern Sea did not produce Ziliujin.

Ziliujin from overseas flowing into the big black market - was directly traded with the foreigners. It was a fixed line, with a fixed group of people. It would not be transported from someone else's location due to the risk being too high.

If someone truly was using the Southern Sea as a cover to control the Southwest Ziliujin black market from a distance – whoever behind it was taking such a big risk, hiding away so deep, their objective certainly was not just to buy and sell Ziliujin.

Chang Geng: "The Southern Sea is not within the country; we also have limited ability. We sent people to the Southern Sea several times, and they all returned in vain. This is one thing - there was also the priest, Jing Xu, who has yet to make his appearance. Yifu, I think that when a savage bandit had been exposed to Ziliujin, he would never think of finding the farming puppets to do fieldworks on the mountain."

After listening, Gu Yun was quiet for a moment, then he stood up and blew a long whistle. A Black Eagle quietly descended from the sky and landed in front of him.

Gu Yun's brow was slightly crinkled. He then gave out three orders in the blink of an eye.

"Two teams of Black Eagle scouts take this map, investigate the territories of the three major bandit leaders of the Southern Frontier, we must first capture the leaders!"

"Imprison the defensive troops of the inspector, thoroughly find out who had drawn out this plan for Kuai Lan Tu and let him use this method to provoke Fu Zhi Cheng and the bandits."

"Interrogate Fu Zhi Cheng, Ji Ping, you go."

Everyone took their leave as they received their orders. After Gu Yun finished, he could not help but narrow his eyes. Even Shen Yi hadn't noticed something was wrong, yet Chang Geng had already pulled him: "Yifu, isn't it...Did you bring your medicine? It will get brighter soon, let's take a break first?"
