In the next half month, the Beifu soldiers launched several large-scale siege battles, and both sides had casualties, and with the slow experience of defending the city, the casualties of the Qiang army in Xuchang City decreased one by one, and the casualties of the Beifu soldiers increased, but the strong city defense of Xuchang City did not have too much damage, and it could hold on to the attack for at least two months!

And on the twentieth day, Liu Yu finally sent back the news, has found the traces of the former Qin reinforcements, the former army of 20,000 cavalry has been less than 200 miles away from Xuchang, three or five days can be reached, another day, Liu Yu again sent back the news, the former Qin reinforcements of the army of 80,000 people, led by the former Qin general Fu Rong, has come to the observation point set up by Liu Yu, only more than 200 miles away from Xuchang!

In addition, the observation point set up on the Rushui also came with news that the 20,000 naval troops and 500 warships of the former Qin also followed the Rushui River and went downstream, and it is estimated that they arrived in Xuchang City at the same time as the forward cavalry.

On the third day when the Beifu soldiers and the Yuzhou army got the news, the Xuchang city also got the news, and the morale was greatly boosted, and the cheers of the Qiang army were heard in the city from time to time, and Xie Xuan also took the opportunity to issue an order to retreat, and the Beifu soldiers and water divisions were currently evacuated at full speed along the Rushui to Huaishui, and the Beifu soldiers and land troops were deployed outside the city of Xuchang in an orderly manner to evacuate the siege equipment to Nanyang County.

The Qiang army in Xuchang City was ready to move, and many generals took advantage of the retreat of the Beifu soldiers to ask for battle, but were rejected by the cautious Yao Chang.

"Xuan Shuai, we have to withdraw at the moment, but now our cavalry needs to be outside Chen Ge City to make a decision, so that the Qiang army in Xuchang City may not be able to leave the city, right?"

Now the development of the situation is changing according to his plan, but at that time, the guard rank obviously ignored the fact that there was no cavalry in Xuchang City, and only now did he realize that this was likely to be a fatal loophole!

"Hehe, Xiaojie, you finally realized this problem!" Xie Xuan said with a slight smile.

"I've thought about this a long time ago, do you know? Our cavalry is not only placed outside Xuchang City to prevent the Qiang army from going out of the city to pursue this task! ”

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

"If you don't use the cavalry to break off the rear and prevent the Qiang army from leaving the city, does the cavalry have other more important tasks?" Xie Yan, like Wei Jie, didn't realize the problem of cavalry until this moment, and asked with a frown.

"There are 20,000 cavalry among the reinforcements of the former Qin, if these 20,000 cavalry do not try to slow down their march, once they stick to our army, it will be a one-sided situation!" Xie Xuan said casually.

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

"Therefore, our 10,000-5 cavalry must go to the northwest direction, find a pass that is easy for cavalry to charge, and buy time for our infantry to retreat!" Wei Jie said with a smile.

The so-called one reason and all the reason, Xie Xuan's meaning is already obvious, the best choice for the cavalry of the Beifu soldiers and the Yuzhou army is not to break off the rear outside Xuchang City, but to prevent Fu Rong's cavalry from supporting quickly, otherwise, the back road of the Beifu soldiers and the Yuzhou army is likely to be cut off by the former Qin cavalry!

"The eldest brother is really a last resort, Xie Yan admires!" It was only at this moment that Xie Yan woke up like a dream and said admiringly.

"It's not that Xie Xuan has no last resort, I'm just taking advantage of the trend!" Xie Xuan smiled slightly.

"Herald, pass the order, only one thousand cavalry of the Yuzhou Army will be left outside Xuchang City, and the rest of the cavalry will be led by Sun Wuzhong and Tan Daoji, and go to the location chosen by Liu Yu to ambush Furong's cavalry!"

"Tonight, the baggage soldiers and the siege soldiers exchanged, the siege soldiers and the baggage retreated together, led by Wang Hong Mao Xiuzhi, set up an ambush fifty miles north of Nanyang, wait for us to meet, and the baggage soldiers will stay behind!"

Under Xie Xuan's arrangement, nearly half of the elite soldiers of the Beifu Army and the Yuzhou Army can be dressed as heavy soldiers and logistics soldiers to retreat at the moment, bury their pockets, and wait for the Qiang army in Xuchang to go out of the city to pursue.

In the middle of the night, after the elite of Xuchang who dressed as heavy soldiers evacuated, the Beifu soldiers and the cavalry of the Yuzhou army also began to withdraw to the northwest.

"Father, why did they leave only the former cavalry? Aren't you afraid that we will open the city and pursue it? ”

Previously, he had supported Ruyin in vain, and he had been suppressed in the city these days, Yao Yun had been waiting impatiently for a long time, and he was already ready to move!

"Xie Xuan is Xie Xuan after all, although he intercepted the rescue stragglers sent by our army, he did not take it lightly, and in addition to attacking the city with all his might, he also arranged a sentry point in the north, thinking that His Majesty's reinforcements have been discovered by them on the march path!"

Although the besieging Jin army has begun to retreat, Yao Chang's heart is not easy, he is holding on to waiting for help and pursuing out of the city It is difficult to choose!

"What the lord said is that the cavalry of the Jin army is estimated to have gone to the northwest to confront the cavalry of the Furong Overseer, so as to buy time for the retreat of the Jin army's foot soldiers!" Zonghou nodded and said.

"Then what are we waiting for, open the city gate now, attack with the whole army, and kill him!" Yao Yun said excitedly.

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

"Don't be in a hurry, wait and see, it's more than two hundred miles to Nanyang, and we have to make sure that the cavalry and sailors of the Beifu soldiers can't go out of the city before they have time to turn around and come back to help!" Yao Chang shook his head and said.

"Pass the order, pay close attention to the movements of the Beifu soldiers and cavalry, and at the same time, all the soldiers in the city are ready to go out of the city to pursue!"

Zonghou opened his mouth, and stopped talking, this father and son are obviously two extremes, one is radical and adventurous, the other is steady, and now the fighter plane is fleeting, he actually supports Yao Yun in his heart, if he wants to pursue, he is bound to go out of the city to pursue as soon as possible, and it will change later, but Yao Chang's words are not unreasonable, if they go out of the city at this time, the Beifu Soldiers and Naval Divisions and the Jin Army cavalry will only have to turn back all the way to help, and the Qiang army will not be able to eat and walk!

At the same time, the Beifu soldiers outside Xuchang City have only more than 10,000 baggage soldiers and elites left in the formation of defense, to prevent the Qiang army from going out of the city to raid, another day later, the more than 10,000 Beifu soldiers under the leadership of Xie Xuan and Wei Jie, also began to evacuate, the Beifu soldiers retreated after the retreat was a little panicked, obviously to march quickly!
