During this time, Gu Yun had to rush back and forth due to the refugee uprising and the rebels forcing the Emperor to abdicate, but Gu Yun's communication with Cai Fen in the Northern Frontier was not interrupted. If Jiangnan was already a tragic situation of ‘the tears of the survivors are in the dust of the earth’, he did not need to think carefully about what was going on in the Northern Frontier.

The blood feuds between the Barbarians and the Central Plains, perhaps they would last until a hundred years later, only when those of these two generations died off could they be alleviated slightly.

But now they came for a truce, what could it possibly mean?

Gu Yun just arrived at the Northern Camp, but before he even had time to drink water, Cai Fen's letter came.

The contents of the letter were simple, but there was a lot of information in just a few sentences: With the two armies confronting each other for so long, each had their scouts and spies planted inside the enemies. The people lurking in the enemy's line reported that in spring, Jia Lai once fell gravely ill, from then on, they had not seen him appear again.

What was even more strange was that his eldest son, in the name of filial piety, had not been seen all day, all his duties were temporarily taken over by the second son.

Jia Lai had three sons, all were birthed by one woman. They imitated the Han system and made the eldest son their crown prince. With the father bedridden, it was not unusual for his sons to compete with each other in displaying their filial piety. But to the point where the First Prince no longer paid any mind to affairs, letting his younger brother handle everything, was it appropriate?

According to this description, what happened in the Barbarian tribes seemed to have come to light — the talented Second Prince was unwilling to live under the shadow of his brother simply because he was born a few years too late. In some way, he had put Jia Lai and the crown prince under house arrest and usurped the throne.

The current commander of the Northern Camp said, "Marshal, in addition to the thirteen conditions, the Eighteen Tribes also agreed to send Jia Lai's youngest son here as hostage, giving us a tranquilizing pill for the next stage of peace talks. General Cai had just informed that the little Man boy's carriage will enter the border soon. They have sent their pass to the court awaiting approval. I was about to send someone to the Marquis' Manor, but you arrived just in time."

With that, he handed Gu Yun another booklet of documents.
