In the next half month, the Beifu soldiers launched several large-scale siege battles, with each side suffering casualties. As they slowly realized the experience of defending the city, the casualties of the Qiang army in Xuchang City gradually decreased, and the casualties of the Beifu soldiers increased accordingly. However, the solid city defense of Xuchang City did not cause much damage, and they could at least last for two months to be attacked!

On the 20th day, Liu Yu finally sent back the news and found the traces of the reinforcements of the Former Qin. The 20,000 cavalry of the Former Qin army was less than 200 miles away from Xuchang, and it was only three to five days to reach. Another day later, Liu Yu sent back the news again that the 80,000 reinforcements of the Former Qin army, led by the Former Qin general Fu Rong, had already come to the observation point set by Liu Yu, which was only more than 200 miles away from Xuchang!

In addition, news came from the observation points set up on the Ru River that the Former Qin Dynasty, 20,000 naval troops and 500 warships also followed the Ru River and were probably arriving in Xuchang City at the same time as the vanguard cavalry.

On the third day after the Beifu soldiers and Yuzhou soldiers received the news, Xuchang City also received the news, and the morale was suddenly boosted. The Qiang army cheered from time to time in the city. When Xie Xuan also took the opportunity to issue an order to retreat, the Beifu soldiers and naval troops were evacuating at full speed along the Ru River to the Huai River. The Beifu soldiers and land troops were deploying defenses outside Xuchang City, while orderly evacuating the siege equipment to Nanyang County.

The Qiang army in Xuchang City was already ready to move. Many generals took advantage of the retreat of the Northern Mansion soldiers and supplies and requested to go to war, but were rejected by the cautious Yao Chang.

"Supervisor Xuan, we have to retreat now, but now our cavalry needs to be outside Chen Ge City to cut off the rear. In this way, the Qiang army in Xuchang City may not necessarily leave the city, right?"

The situation is now changing according to his plan, but at that time, the Wei Jie obviously ignored the fact that there were no cavalry in Xuchang City. It was not until now that he realized that this was likely a fatal loophole!

"Haha, Xiaojie, you finally realize this problem!" Xie Xuan said with a smile.

"I have thought about this for a long time. Do you know about Xiaojie? Our cavalry is not the only task of stopping the Qiang army from leaving the city to pursue!"

After Xie Xuan finished speaking, Wei Jie felt Hao Ran and suddenly realized that there was still a huge gap between him and Xie Xuan in terms of combat experience!

"Don't use cavalry to cut off the rear to prevent the Qiang army from leaving the city, do the cavalry have other more important tasks?" Xie Yan, like the Weijie, did not realize the problem of cavalry until now, and frowned and asked.

"There are 20,000 cavalry among the reinforcements of the Former Qin Dynasty. If these 20,000 cavalry do not try to delay their marching speed, once they stick to our army, it will be one-sided!" Xie Xuan said as if nothing had happened.

"What kind of damage and lethality will the 20,000 Di cavalry cause?"

"So, our 10,000 cavalry must go to the northwest direction, find a pass that is easy for cavalry to charge to guard it, and buy time for our infantry to retreat!" Wei Jie said with a smile.

The so-called "one principle is clear and all principles are clear". Xie Xuan's meaning is already very obvious. The best choice for the cavalry of the Northern Mansion Army and the Yuzhou Army is not to cut off the back outside Xuchang City, but to stop Fu Rong's cavalry from supporting quickly. Otherwise, the retreat of the Northern Mansion Army and the Yuzhou Army is likely to be cut off by the Former Qin cavalry!

"Brother is indeed perfect, Xie Yan admires it!" It was not until this moment that Xie Yan woke up like a dream and said in admiration.

"It's not that Xie Xuan's plan is completely done, I'm just following the trend!" Xie Xuan smiled slightly.

"If the order is sent, only a thousand Yuzhou cavalry will be left outside Xuchang City, and the remaining cavalry will be left to the location chosen by Liu Yu to ambush Fu Rong's cavalry!"

"At midnight tonight, the baggage troops and the siege elite troops will be exchanged. The siege elite troops and the baggage retreat together. Leaded by Wang Hongmao Xiuzhi, set up an ambush fifty miles north of Nanyang, waiting for us to meet, and the baggage troops will be left behind and the back will be cut off!"

Wei Jie was convinced when he heard it, and the baggage soldiers rarely participated in the battle, so it was naturally inconvenient to retreat and arrange an ambush circle. With Xie Xuan's arrangement, nearly half of the elite generals of the Northern Mansion Army and the Yuzhou Army could dress up as baggage soldiers and logistics soldiers to retreat, bury their pockets, and wait for the Qiang army in Xuchang to leave the city to pursue.

In the middle of the night, after Xuchang was evacuated, the Northern Mansion soldiers and the cavalry of the Yuzhou Army also began to evacuate in the northwest. At this time, Yao Chang, Yao Yun, General Zonghou and others naturally watched the movements of the Northern Mansion soldiers and the Yuzhou Army on the city wall.

"Father, why did they only leave the cavalry behind before? Are they not afraid of us opening the city to pursue it?"

Previously, support from Ruyin was unsuccessful and was suppressed in the city over the past few days. Yao Yun had been impatient and was ready to move!

"Xie Xuan is Xie Xuan after all. Although he intercepted the scattered cavalry sent by our army to seek help, he did not take it lightly. While attacking the city with all his might, he also set up sentinels in the north. I think His Majesty's reinforcements have been explored by them!"

Although the besieged Jin army had begun to retreat, Yao Chang was not relaxed. He was struggling to make a decision between waiting for aid and pursuing the city!

"What the lord said is that the cavalry of the Jin army is probably heading to the northwest and confronting the cavalry of the Fu Rong Army General, so that it can buy time for the retreat of the Jin army infantry!" Zonghou nodded and said.

"Then what are we waiting for? Open the city gate now, the whole army attacks, and kill him a fallen flower!" Yao Yun said excitedly.

"There are still thousands of cavalry in the city. I am willing to be a vanguard and lead troops out of the city to chase and kill the Jin army!"

"Don't be anxious, wait and see. There are more than 200 miles to Nanyang. We need to confirm that the cavalry and navy of the Northern Mansion soldiers did not have time to turn around and return to the rescue before leaving the city!" Yao Chang shook his head and said.

"Send the order to pay close attention to the movements of the Navy and Cavalry of the Northern Mansion Army. At the same time, all soldiers in the city are ready to go out of the city to pursue!"

Zonghou opened his mouth and wanted to speak but stopped. The father and son were obviously two extremes, one was radical and the other was steady. The fighter opportunity was fleeting. He actually supported Yao Yun in his heart. If he wanted to pursue, he would definitely leave the city to pursue him as soon as possible. However, Yao Chang's words were not unreasonable. If he left the city at this time, the North Mansion Navy and the Jin cavalry could only turn back and rescue, and the Qiang army would not be able to take it!

At the same time, the Northern Mansion soldiers outside Xuchang City were only left with more than 10,000 baggage soldiers and elite troops to form formation defense to prevent the Qiang army from leaving the city to raid. Another day later, the more than 10,000 Northern Mansion soldiers, led by Xie Xuan, Wei Jie and others, also began to evacuate. The Northern Mansion soldiers were a little panicked when they retreated, and they obviously wanted to march quickly!
