After review, most of the Huns soldiers who surrendered before were incorporated into the border army. Some of them were herdsmen themselves and had old, weak, women and children at home, so Shan Xin let them go.
A very small number of them were the princes and nobles of the Xiongnu. They had no choice but to surrender, and even if they surrendered, they still beat and kicked their original subordinates, acting like nobility.
Shan Xin did not tolerate them, so he directly pulled these guys out and beheaded them on the spot to win over people's hearts.
As a result, more than 300,000 troops were gathered in the fifteen border cities.
But with so many people guarding here, the logistics supply of food and grass became a problem. After much consideration, Shan Xin had to select 100,000 troops to return to the imperial city and continue to be stationed in the Longtian camp.
After all, the entire Dashang army only had so few troops, although with the surrender of the Huns, the army barely reached 700,000.
However, Dashang was surrounded by neighboring countries and was surrounded by crises. During this period, it was also unhappy with Liang Guo, and troops had to be stationed at all borders.
It is indeed inappropriate to concentrate nearly half of the troops in the northern border city.
Bai Hua also knew this very well. Although Zhao Rui ordered him to lead 10,000 soldiers and horses to the northern border first, he still divided 30,000 soldiers and asked them to return directly to Longtian Camp.
He himself took 20,000 light cavalry and rushed to the border without stopping.
The two people hit it off as soon as they met. They hid in the room and discussed the map for a while. Although they had different opinions on conquering the nineteen countries in the world from the north, their general strategies were quite different.
When he was so excited, Shan Xin actually pulled Bai Hua to become his brother.
Bai Hua was not polite. He was several years younger than Shan Xin, so he willingly became his younger brother.
But just when the two were about to burn incense to worship heaven and earth, Zhao Rui and Li Fei suddenly barged in.
"Two generals, why is this such a big battle!"
Shan Xin and Bai Hua quickly stood up to greet them.
"Prince Rui, General Shan and I are close to each other and want to become brothers!"
When Zhao Rui heard this, he immediately became interested and picked up three sticks of incense from the side.
"In that case, I'll join in the fun and swore sworn vows with the two generals!"
Bai Hua was stunned for a moment. Zhao Rui had a special status. Once the time came, the emperor would definitely rectify his identity and restore his status as the King of Northern Zhao.
As for the two of them, one is a cavalry general and the other is a feather general.
Although he was favored by the emperor and commanded a large army, his official position was all fourth-grade, which was equivalent to that of Li Fei. There were even many senior generals in the army with the same rank as them.
If it weren't for the command arrows given by Murong Bing himself, these old generals might not necessarily listen to them.
With such a status, it is indeed somewhat unqualified to be called brother-in-law to Zhao Rui.
Shan Xin didn't know what to say. He was extremely excited after hearing Bai Hua tell Zhao Rui's true identity these days.
After all, he was a border general who always interacted with a eunuch, so he could easily be impeached.
But now that Zhao Rui wants to become his brother, he is indeed flattered.
"Prince Rui, I'm afraid there's something wrong with this. We are all warriors in the army, and you..."
Zhao Rui didn't care so much and even pulled Li Fei over.
"My current public identity is still that of a eunuch. What's wrong with that? Li Fei will also join the border army from today on. Let's all sworn together to completely solve the border troubles of the Xiongnu, and then lead the army to unify the world for me, Great Shang."
As soon as these words came out, Bai Hua and Shan Xin no longer had any worries. Besides, being able to become brothers with Zhao Rui was a blessing they had cultivated over several lifetimes.
After the four people determined their ages, they each bit their fingers and dripped blood into the four wine bowls.
Then they knelt neatly in a row, each holding three sticks of incense in their hands, with firm eyes.
