"Lord Shefu, it was the Han army! It was the Han army that drove them out of their original tribes and brought them here!"

A nobleman from the tribe explained the reasons to Shefu in detail.

"How despicable! The Han army has betrayed their promise!"

Shefu was furious upon learning that he had lost all his eastern territories.

Li Ru stepped forward and said with a smile, "Why is Lord Shefu angry? Isn't the Han army doing you a great favor by doing this?"

Shefu was slightly taken aback upon hearing this, then nodded: "What you say makes sense, sir. This way, we won't have to go through the trouble of gathering our own followers!"

Now that Murong Tu has lost 20,000 elite troops and the strength of the Xianbei in the east has been greatly weakened, it is the best time for the Wuhuan to advance westward and seize the grasslands.

Subsequently, Shefu ordered all the able-bodied men in the tribe to gather together, totaling more than 50,000, and set off westward to attack the eastern Xianbei. The remaining herdsmen followed behind with their cattle and sheep.

At this point, the Northern Wuhuan left their original home and entered the grasslands.

Meanwhile, the scions of prominent families and merchants who ventured deep into the heart of Yilou discovered two gold veins after careful surveying, which greatly excited them.

According to the rules of the imperial court, 50% of the gold mine output belonged to the imperial court, while the remaining 50% belonged to these aristocratic families and merchants. They were responsible for all mining matters, and the imperial court only needed to send people to supervise.

These aristocratic families and merchants, while sending messengers to their clans, also began to capture Yilou people and enslave them to mine.

A month later, Shefu led the Wuhuan army to the eastern Xianbei territory and launched an attack.

Along the way, the Wuhuan people made rapid advances, successively conquering more than a dozen eastern Xianbei tribes, encroaching on most of Murong Tu's territory, and began to settle in the Hulunbuir region.

Murong Tu, who had reclaimed his tribe, was also forced to lead his herdsmen westward and settle on the banks of the Kerulen River, west of Manzhouli.
