As time went on, nearly a thousand Xiongnu soldiers climbed the city walls, but none of them made any progress.

Upon seeing this, Xie Zhiyu, who was at the front of the army, immediately sent another 10,000 men to carry more ladders and charge forward.

With the addition of another 10,000 soldiers, more and more soldiers were able to climb the city walls at the same time, and finally some were able to gain a foothold and begin a counterattack against the defenders.

Soon, the Xiongnu army opened up small battlefields on the city walls and gradually expanded them.

Seeing this, Xie Zhiyu, who was watching the battle, couldn't help but reveal a hint of a pleased smile.

Unfortunately, his smile didn't last long before it froze on his face.

Because Han generals such as Xu Chu, Hua Xiong, and Yan Liang also climbed onto the city wall and began killing the Xiongnu troops.

With the support of a group of fierce generals, the advantage that the Xiongnu army had painstakingly built up crumbled instantly, and they were quickly driven off the city walls again.

"Keep pushing! We must take the city today!!"

Xie Zhiyu gritted his teeth and ordered the attack to continue. The fact that the Xiongnu troops were able to climb onto the city walls seemed to give him hope of breaking through the city.

Under the intense pressure of the Xiongnu cavalry, the Xiongnu troops had no choice but to grit their teeth and continue to surge towards Gaochang City like a tidal wave.

This time, many soldiers were able to climb onto the city wall and launch a counterattack, but they did not last long before being scattered by Xu Chu, Hua Xiong and others.

The siege lasted for two hours. With each attack, Gaochang City seemed to be on the verge of collapse, but it always held on at the last moment.

Finally, after leaving behind 10,000 corpses, Xie Zhi had no choice but to retreat.

Xie Zhiyu glanced deeply at the Han general on the city wall, his eyes filled with apprehension.

He knew that as long as those Han generals were present, Gaochang City would be difficult to capture.

Moreover, of the 70,000 Xiongnu troops, only 40,000 remain. Only by replenishing our ranks can we continue to launch attacks.

After withdrawing his troops, Xie Zhiyu also led his army back to the temporary royal court, preparing to recruit young men from the occupied countries again in order to fight again.

On the Gaochang side, after several major battles, most of the Western Regions allied forces under its command were killed or wounded, leaving fewer than 20,000 men.

Yuan Shao then immediately sent people to issue conscription orders to the various states in the rear, preparing to continue the war against the Xiongnu.
