"The Ziliujin black market in the territory of Great Liang is extremely unruly." Li Feng said, quickly diverting the topic. "This time, I sent people to conduct a private investigation in disguise and found that a large part of the supply actually came from outside the country."

Gu Yun immediately understood as he heard this that those officials who leaked the goods in the territory had already received news through various connections. They had all quieted down and assessed the direction of the wind. What Jiang Chong and his men discovered were only some small fishes and shrimps secretly digging from the mines. Thus he kept quiet and listened.

Li Feng continued his words: "Imperial Uncle often walks in the frontiers, you must be a lot more knowledgeable than those of us sitting in the capital all day much like frogs sitting at the bottom of a well. Do you know where these private miners usually travel to?"

Gu Yun: "To answer His Majesty, they are generally on the Northern Barbarian grasslands."

"Correct," Li Feng laughed. "Although that's not all — Imperial Uncle, come look at this."

Gu Yun hesitantly accepted the confidential report Li Feng threw to him; as he swept his eyes over it, his mind suddenly exploded.

The report listed in detail every single trading line the private miners sold their Ziliujin to; Gu Yun knew most of them by heart, except for the last one that read — 'Lou Lan Kingdom'.

How come Lou Lan is here?

Li Feng: "So?"

Countless thoughts raced through Gu Yun's heart, cold sweat quickly breaking out: "Your Majesty, the Black Iron Camp and Lou Lan Kingdom have been neighbors for many years. I have never been aware that there is a Ziliujin mine in Lou Lan. Please pardon my rudeness, dare I ask who had brought forth this report? What is their evidence?"

"Hey, Imperial Uncle has thought too much," Li Feng said with a smile. "I never said that you have connections with those thieves who were privately mining. There is nothing strange about you not knowing about this matter."

Gu Yun took a deep breath, indicating that he was listening carefully.

Li Feng: "It's a long story. Imperial Uncle had moved out with your troops to the Southern Frontier from September last year. When you were not here, Lou Lan Kingdom had asked the Black Iron Camp soldiers who were stationed behind for help, as they wanted to encircle and eliminate a group of bandits.

"At that time, General Qiu Wen Shan had sent out troops, later bringing back complete victory, killing hundreds of desert bandits, and rescuing a group of Tian Zhu merchants who they captured. Because these merchants had the border pass of Great Liang, General Qiu had escorted them to the West Station. Unexpectedly, they later discovered at the station that the merchants' passes were fake."
