"Cut the needless courtesy," Gu Yun regained his energy. "What happened? He Rong Hui sent you here?"

Black Eagle: "Yes!"

Gu Yun: "Let me see the letter."

He unfolded the letter given by the soldier and swiftly read through it. The handwriting of the Eagle faction's commander He Rong Hui was incredibly hideous, conveying everything in a short and brief manner.

At the end of the month, two small countries at the Western Regions - Ku Cha and Qie Mo had some dispute regarding the matter of border trade. Still, the affairs between the countries of the Western Regions were to be resolved within themselves, it was not convenient for officers of Great Liang to intervene. Thus, they did not pay much attention to this at first.

Lou Lan and these two countries just happened to create a triangle. The King of Lou Lan had sent his brother as an envoy, serving as a connection to help the two sides reconcile, but their group had met its demise at the border of Ku Cha, the entire troop was wiped out.

At first, it was assumed to be desert bandits. But afterward, as the King of Lou Lan made a thorough investigation, they discovered the emblem belonging to the sword of the Imperial Guards of the Ku Cha Kingdom among the ruins of the aftermath. Thus, they had promptly gone to question this country.

The Ku Cha Kingdom denied everything through and through, claiming that Lou Lan was showing favoritism towards Qie Mo, even humiliating Lou Lan's envoys. The King of Lou Lan sent their prince as the head, leading three thousand riders to Ku Cha, pressing them to shed light on this matter.

In the beginning, Ku Cha had kept their doors closed and refused to respond, then suddenly opened the gates, with hundreds of 'Sand Tigers' inside.

The so-called 'Sand Tiger' was a war chariot that ran in the desert, extremely heavy, and consumed a great amount of Ziliujin. Their working mechanism was also extremely complicated.

Gu Yun had clashed with them when fighting the rebellion in the Western Region a decade ago. At that time, there were only three large sand tigers on the opponent's side, yet they had almost managed to trap half of his still inexperienced Black Cavalry. But as far as he knew, those three Sand Tigers were the result of all the Western Region countries pouring their resources together to create.

Gu Yun stood up abruptly, his brows in a deep scowl, his fingers unconsciously spinning the wooden beads in his hands- this was too similar to the case of the southwest rebellion. He lowered his voice and asked: "Is it truly a Sand Tiger, not just an empty shell?"
