Chapter 1476

Duan Liuqing walked to Duan Yu holding the secret letter.

Red?

Duan Yu's brows furrowed instantly.

The secret orders and secret letters of the Military Intelligence Department had levels of classification.

This was used to determine whether higher-level personnel needed to handle them.

The Military Intelligence Department had developed for three years now, and apart from Liu Bai Tu, the highest commander of the Military Intelligence Department, the first, second, third, fourth, fifth, and sixth departments each had their own commanders in charge.

Under the commanders, there were also managers for each branch.

In this way, work efficiency would be greatly improved.

Red was the highest level among all secret orders and secret letters, and it had to be delivered to Duan Yu's hands immediately.

Apart from red secret orders, most of the others stopped at the step of Liu Bai Tu.

Liu Bai Tu would consider whether to submit those that needed to be submitted.

Duan Yu took the red secret letter from Duan Liuqing's hand, and Duan Liuqing stepped back and walked out of the study.

Duan Yu unfolded the secret letter and read it at a glance.

As he delved deeper into the content, Duan Yu's brows gradually locked.

After browsing through all the content, Duan Yu handed the letter to Guo Jia beside him.

"Gongda, you take a look first."

Guo Jia handed the secret letter to Xun You in the lower position.

"This..."

Just by looking at it, Xun You's face changed drastically.

"The Southern Xiongnu... have rebelled?" Xun You widened his eyes, his face full of disbelief.

Duan Yu took a deep breath, nodded, and said: "It should be so."

Xun You frowned and immediately replied: "But... if the Xiongnu have rebelled, then Wenhe, Wuyou, and the others could not have failed to notice."

The red secret letter from the Military Intelligence Department was not sent by Jia Xu and the others.

Because if Jia Xu and the others were sending a letter, it would not be a red secret letter from the Military Intelligence Department, but should have been in the form of a report.

This letter... came from the Military Intelligence Department's placement in the Northern Expedition Army.

The so-called Northern Expedition Army was the large army led by Jia Xu, Li Ru, and Cheng Yu who were currently fighting in Bingzhou.

And the Southern Expedition Army was led by Tie Shitou in Hanzhong.

Among them, whether it was the Southern Expedition Army or the Northern Expedition Army, there were a large number of Military Intelligence Department personnel monitoring the generals at all levels.

It was similar to the Brocade Guard of the Ming Dynasty.

And this letter came from the Military Intelligence Department.

This level of intelligence would be repeatedly confirmed, and it was almost impossible for it to be false.

"I am also very strange. Since the Xiongnu have rebelled, Wenhe, Wuyou, and Zhongde are the closest to the Xiongnu; it is impossible that they did not notice. And if the Xiongnu rebelled, the first report from the Military Intelligence Department should have reached them, and then been forwarded to me." Duan Yu was somewhat puzzled.

Xun You reacted a bit faster.

"My King, the subordinate wants to see the recent movement direction of the Northern Expedition Army." Xun You said immediately.

Duan Yu nodded to Guo Jia and Fa Zheng beside him.
