Because Cheng Yu had begun planning his strategy in the Western Regions several months earlier, he quickly learned about Lan Zhi's situation.

The findings of the Investigation Division were no different from the guesses of Xun You, Li Jue, and others.

After reading the contents of the note in his hand, Xun You couldn't help but frown.

Xun You didn't care about Lan Zhi's identity, but another piece of information that the Investigation Division had obtained made him realize something was amiss.

"Prefect Xun, what has happened?"

Seeing Xun You suddenly frown, Li Jue below couldn't help but ask, and the others in the hall also looked at Xun You at the head of the table.

"According to reliable sources, the Later Cheshi Kingdom, which controlled Gaochang, seems to have had contact with the Xiongnu and Xianbei people!"

As they were talking, Xun You had someone hand the note to Li Jue below.

"What?"

This news caused a change in the expressions of Li Jue and everyone else in the hall.

"Hmph~ These barbarians of the grasslands are indeed still up to their old tricks, actually extending their reach into the Western Regions?"

After reading the contents of the note, Li Jue's face turned frosty, and he slammed his hand on the table and stood up.

Li Qiu, standing to the side, also frowned and said in a deep voice:

"It seems that the coup in Gaochang was not as simple as it appeared on the surface. The Xiongnu and Xianbei people probably wanted to take the opportunity to regain control of the Western Regions."

If they succeed, it will likely bring great trouble to our Han Dynasty. We must inform His Majesty of this matter as soon as possible!

"good!"

Xun You nodded, then looked at Zhang Xiu below, "Jinyi, go back and prepare now. Don't wait a few days. Once you're ready, take Lanzhi and head to Luoyang immediately!"

"promise!"

Zhang Xiu knew the matter was urgent, so after bowing to Xun You, Zhang Ji, Li Jue, and others, he hurriedly left.

After everyone had left, Xun You hurriedly went to his study, wrote down the news about Lan Zhi and the Western Regions in a secret letter, and then ordered someone to rush to Luoyang as quickly as possible.
