Give Li Rufeng more troops to ensure that Li Rufeng has enough troops to defeat Li Chengdong, and use this opportunity to establish a good relationship with the Hongguang court.

At this time, Li Chengdong exerted great power under the city of Hanyang, only with 8,000 soldiers and horses, Jiang Tianyi did not dare to go out of the city, and the food and grass in the city were insufficient, and more and more rebels went out of the city, or surrendered to the Qing army, or dispersed.

Jiang Tianyi struggled to support in the city, which frightened Jin Sheng, Jin Sheng hurriedly mobilized troops and horses in Luzhou Mansion and Huizhou Mansion to the north to reinforce, and Huang Degong also wanted to raise troops for reinforcements.

However, after receiving the two troops of King Lu and Emperor Longwu approaching Huizhou Mansion, he had to lead the army to garrison Congshan Pass to ensure that the Hongguang court was not subverted.

Li Chengdong didn't know that Duoduo and Bolo were heading towards Xiangyang Mansion, and he was the only one in De'an Mansion, and when he knew that Duoduo's army was moving westward, Jin Sheng had led 30,000 Ming troops to reinforce him.

Li Chengdong immediately gave up the capture of Hanyang, led the army to retreat to the north, and retreated to Yingshan County, his eyes were straight, why did Yingshan County have another Ming army?

The Ming army in Yingshan County was Li Rufeng's department, he led 5,000 soldiers and horses to gallop to Hanyang, and advanced to Yingshan County.

It was not until Ling Jingyang repelled Geng Zhongming and determined that Duoduo's army had left, that he ordered Li Rufeng to continue to reinforce Hanyang, and without waiting for Li Rufeng's army to advance, Li Chengdong led the Qing army to withdraw to Yingshan County.

The Qing army suddenly withdrew, which Li Rufeng did not expect, and he did not dare to lead the newly formed soldiers and horses to fight with Li Chengdong in the field, but Gao Ding was eager to try.

According to the information sent back by the scouts, this group of Qing troops also had quite effective combat effectiveness in Li Chengdong's headquarters, and the other Qing troops were either rebels who surrendered, or they wanted to follow the Qing army to burn and kill and plunder scoundrels.

Gao Ding kept instigating Li Rufeng to have a decisive battle with the Qing army, Li Rufeng was almost moved by him, but he remembered Ling Jingyang's special advice, and still resisted the desire to go out of the city and fight a decisive battle with the Qing army, and ordered all troops and horses to defend Yingshan County.

The Qing army was in a dilemma, with Li Rufeng's 5,000 Ming troops in front and tens of thousands of Ming troops led by Jin Sheng, Li Chengdong was forced to ask Wu Sangui for help.

Wu Sangui cooperated with Azig in Xiangyang Mansion at this time, and the attack of Azig Xiangyang Mansion was resisted by the Ai Nengqi Department of the Great Western Army, and he did not break through the defense line of the Great Western Army for a while.

Not only did he not break through the defense line of the Daxi Army, but Zhang Xianzhong, the emperor of Daxi, personally led 200,000 troops to reinforce Liu Wenxiu, and the morale of the Daxi Army increased dramatically, and the Qing army lost troops in several attacks.

As a famous general of the Manchu Qing Dynasty, Azig had a very long-term strategic vision, believing that the concentration of the Qing army in Xiangyang Province was not conducive to the development of troops.

It happened that Li Chengdong was in De'an Mansion, so Wu Sangui led his troops to De'an Mansion to capture De'an Mansion, Huangzhou Mansion, Chengtian Mansion, Wuchang Mansion and other places, expanding the strategic space for the Qing army.

Wu Sangui received the military order from Azig, and almost on the same day, he received Li Chengdong's request for help, and he sighed that this was really a war exploit given to him.

Eager to lead the troops to attack De'an Mansion, Li Chengdong led the troops to retreat westward before Jin Sheng and Li Rufeng formed a siege.

The Qing army was sniped by Li Rufeng's troops, and the blocking battle was very successful, not only allowing Li Chengdong not to retreat, but also buying precious time for the Ming army of the Jinsheng Department.

Jin Sheng led tens of thousands of Ming troops to kill from the back of the Qing army, and the two armies attacked back and forth, and the Qing army under Li Chengdong was almost completely lost.

The Qing army was killed to the point of leaving hundreds of people, Li Chengdong hastily retreated westward, retreated to the vicinity of Zaoyang, and Wu Sangui's army arrived.

Wu Sangui saw that Li Chengdong was beaten like this, how could he not be angry?

Ordered all the troops and horses to attack, most of the Wu soldiers and horses were tired, Wu Sangui in order to boost morale, ordered the troops to enter De'an Mansion, can be a column, this military order reached the whole army, Wu army soldiers and horses morale immediately came up.

Tens of thousands of Qing troops killed the Ming army, and thousands of Ming troops who were pursuing Li Chengdong's department were melted by this sudden attack.

When Jin Sheng and Li Rufeng got the news that Wu Sangui's troops had entered De'an Mansion, the 10,000 Ming troops who pursued the Qing army were almost all wiped out.

Li Rufeng immediately withdrew to Yingshan County, Jin Sheng also hurriedly ordered a retreat, and as soon as the Ming army on both roads withdrew, the Qing army was like a loose war horse, raging in the north-central part of De'an Mansion.

Li Rufeng did not dare to fight with the Qing army in the field, and constantly asked his generals to rush back to Dasheng Pass, and asked Ling Jingyang to increase his troops.

Ling Jingyang asked Zhang Shun to reinforce half a month ago, but he was suddenly attacked by the Qing army of Runing Mansion, and Ao Bai did not attack Nanzhili, which was to avoid stimulating the small court of the Southern Ming Dynasty.

but

It was he who figured out the situation in Huguang and thought that the Ming army in the fortresses such as Dashengguan was a difficult bone to gnaw, and if he didn't gnaw it at this time, it would be even more difficult to gnaw it in the future, so he led the 30,000 Qing army to launch an attack on Jiuliguan.

Ling Jingyang's main force was in Muling Pass, and as a last resort, he was forced to recall Zhang Shun, and led various troops and horses to gallop to Jiuli Pass, and there was no extra troops to reinforce Li Rufeng.

Li Rufeng saw that there were no reinforcements, ordered to abandon Yingshan County, led the Ming army to retreat towards Dasheng Pass, Wu Sangui led the army to pursue, Li Rufeng lost two-thirds of the soldiers and horses on the way to retreat, retreated to Dasheng Pass, and left more than 1,000 people.

Fortunately, there were still thousands of Ming troops in Dasheng Pass, and Li Rufeng withdrew to Dasheng Pass to assist the defenders in resisting the Qing army's attack, and Wu Sangui could not break the city after several attacks.

Wu Sangui also thought that the Ming army in Dashengguan and other places needed to be pulled out, so he and Aobai attacked the fortress group carefully built by Ling Jingyang.

Ling Jingyang was confident that he could resist the Qing army's attack from the north and south, but when Ao Bai attacked Jiuli Pass and Wu Sangui attacked Dasheng Pass, Ling Jingyang found that there were not enough troops under his command, and the soldiers were not all elite.

The Qing army almost broke through the Jiuli Pass in several attacks, and the victory pass was even more precarious under the attack of Wu Sangui's troops.

Chen Yidao, who was stationed at Muling Pass, saw the danger of the western and central fortresses, decisively abandoned Muling Pass, led the defenders to retreat to Dasheng Pass, and Li Rufeng resisted Wu Sangui's attack.

The momentum of the Qing army's offensive is still very fierce, almost every attack, can take away a large number of Ming soldiers and soldiers, fierce fighting to the fifth day, almost all the fortresses outside Jiuliguan are lost, and Jiuliguan is left to hold on.

Dashengguan was even more Wu Sangui's troops climbed the city wall, almost penetrated by the Qing army, in the face of the Qing army's onslaught, the Ming army almost lost confidence, and rumors began to spread in the army.

Many people think that Ling Jingyang is a holy decree, thinking that Ling Jingyang is a national thief, not a real minister of the humerus, and the message is becoming more and more outrageous, and there are more and more Ming army soldiers who surrender to the Qing army by hanging from the city wall at night.

The Qing army outside the city was about to break the city, and rumors spread about the Ming army inside the city, and Ling Jingyang realized that there were traitors inside and were about to cause chaos.

Secretly ordered Fang Xiaoyan to find the traitor, Fang Xiaoyan had already asked the officers of the Special Bureau to enter the army in the name of ordinary soldiers, and in less than half a day, Fang Xiaoyan brought Ling Jingyang a top-secret information.
