Wu Sangui still underestimated this Northern Expedition Army. In his impression, although the Ming army in Guan was increasing its combat power over the years, it had not yet reached the same height as his Guanning Army.

But what he didn't know was that the Northern Expedition Army had the strongest backing, and the entire Ming Dynasty was now operating, turning with military industry as the axis. How much energy does the national power have? No one dared to explain it clearly.

The era when cavalry dominated the world was gone by the roar of the three major arsenals in Songjiang, Denglai and Fuzhou.

They did not learn enough lessons from the Qing soldiers. The two sides fought outside Ningyuan City, and Wu Sangui and Kong Youde suffered heavy losses.

Hou Xuanyan looked at the list of casualties counted and suffered a lot of losses, but in fact the damage was less than one-fifth of the opponent. All the veterans present were all veterans. Although they might not be very accurate in their view, they also knew it.

"This time I'm going to kill Liao cavalry, so it's better to take advantage of the situation to sweep Songjin. Time is too late." Li Haoxian said loudly with his hands ready to rub his hands.

Hou Xuanyan nodded and said, "Wu Sangui, holding the idea of ​​Guanning's soldiers being invincible in the world, has been in a daze for so many years. It is time to wake him up. This dog thief avoids fighting for so long, so I want to see how much he has."

"Today I am watching the battle in front of the battlefield, and Kong Youde's troops are even more difficult to deal with. It seems that we have always overestimated Wu Sangui." Yan Yingyuan said with a frown.

Du Yinxi was the most familiar with the Four Vanderas. Seeing that everyone was underestimating the enemy, he said, "Today we have a large number, and the Liao soldiers failed to fight several times, and all their strength was lost. However, when they regrouped, they could not be easily eliminated. I am afraid that the next bloody battle will be a good fight. We should be careful."

"As soon as one go, it will decline again, and it will be exhausted three times. Since the momentum has been made, how can the Wu and Kong armies be renovated? Tonight's reserve team will attack the enemy camp at night." Hou Xuanyan said to Du Yinxi.

Du Yinxi was overjoyed. He came the latest and was treated as a reserve team by Hou Xuanyan.

In fact, Du Yinxi didn't understand very well. What's the use of keeping a reserve team in war? It was not until Shanhaiguan that he understood Hou Xuanyan's intention.

The reserve team is really a magic weapon for large-scale battles. As long as there are enough soldiers, when your enemies and yourself are exhausted, the appearance of a new force is like a divine weapon falling from the sky.

The battle reserve team during the day was full of enthusiasm. When Du Yinxi brought back the news, these Shaanxi and Gansu soldiers were as powerful as rainbows.

Wu Sangui retreated to the mountain and climbed over the mountain to Songjiang. The Ming army in the Songjin area had not yet evacuated.

In the night, Wu Sangui heard the shouts of killing outside and started to start from the big tent. The war outside illuminated the night sky, and the Ming army was attacking everywhere.

Wu Sangui never expected that after the bloody battle during the day, they would still have the energy to launch such a night attack.

"How is Kong Youde going?"

"The King of Dingnan is killing the enemy. Prince, let's go out to fight as well."

Wu Sangui was used to selling his teammates, for fear that Kong Youde would leave him and escape alone to retain his strength. He used this move too many times, so he was inevitably afraid that someone would use his own way to do it.

It has to be said that the three vassal kings who came from Pidao were broader than the Guanning family. Shang Kexi was beaten for four months and still knew that he would not retreat from guarding Ningyuan, and Kong Youde was even more so.

The Guanning Army has always been a traitor to harm teammates. Since the bloody battle of Hunhe, they knew that they had shrunk into the city and did not come out. The Baigan soldiers and Sichuan soldiers and Zhejiang soldiers who came to fight were both fighting in the bloody battle of Jiannu in Hunhe, but the Guanning Army did not dare to fight.

Kong Youde had already put on the battle, and several personal soldiers hurriedly put on armor for him, but their legs were frozen stiff when they rode on the horse. Kong Youde was strong and strong, and he was the most brave. It was no problem to ride a horse to break through.

The colder than the legs, Wu Sangui's heart, these Ming troops did not reduce the might of the day. These people who Wu Sangui didn't know had no big battle at all. The war during the day was in full swing, and these people were repairing the rear.

On the small battlefield of Ningyuan, there is no way to allow so many people to participate in the battle. Hou Xuanyan gradually learned how to use soldiers correctly. Wars have always been full of variables. The unpredictability of the battlefield determines that the army must reserve reserves a reserve team in the war to deal with emergencies on the battlefield. In addition to responding to emergencies on the battlefield, the reserve team also has the functions of rotation of fatigued troops on the battlefield and local breakthroughs on the battlefield. If the battlefield lasts too long, the front-line troops need to be rotated. When the enemy appears weak points on the battlefield, the reserve team can act as an assault force to break through the defense line with an overwhelming advantage and give a fatal blow to the enemy.

Sometimes leading troops to fight is not necessarily a good thing if there are too many people. Zhao Guangyi's northern expedition to the Sixteen Prefectures of Yanyun was not defeated, but if he had not conquered so many surrendered troops, he would not have been defeated in the end. Due to the ability to pass messages in this era, commanding too many troops to fight is simply a big gamble. Once a problem arises, it is difficult to understand the situation and issue orders.

If the army is deployed properly, the commander can be foolproof and have a particularly accurate grasp of the enemy situation, then it is not a problem whether to leave the reserve team or not. However, no one is truly a leader like a god. Everyone has miscalculation. The so-called "carelessness" will lose all the game. Therefore, retaining the reserve team is actually to provide yourself with insurance and leave a backup plan. When you are in danger, you can still win by surprise.

At this time, the reserve team seems very suitable, and no wonder Napoleon would say: "War is the game where the more reserve teams win."

The gap between the reserve team made it difficult for Wu Sangui to resist, and Kong Youde was even worse than him. During the day, Kong Youde's performance was better than Wu Sangui, so he received special "care". The Qing soldiers from both sides fled along the valley to Songshan Fort and Jinzhou.

There were not many cavalry in the Northern Expedition Army, and it was very difficult to pursue. Du Yinxi decided to give up pursuing the escaped enemy and wiped out the surrounded Qing soldiers on the spot.

One of the four feudalists has been eliminated, and the remaining three are also defeated generals. If the Northern Expedition Army does not fight, it will be a shocking moment.

As it turns out, without cannons and muskets, this army is still the strongest army.

There was no time to celebrate, Hou Xuanyan had already led his troops to Songshan Fort, and the navy followed their steps on the sea, cooperating with the preparation of artillery bombardment and transport troops to land.

At this point in the war, there was an opportunity to finally emerge because of an alliance between Wu Sangui and the Rakshasa Kingdom. The rash attack and support Shang Kexi ended up giving Hou Xuanyan a chance to win.

This battle alarmed the Jiannu of Manchus, and Shengjing immediately sent troops to support Jinzhou. If Song Jin was lost, the gate of Shengjing, Guangning Mansion, would be in front of him.

Dai Shan did not care about his old age and weak strength, so he personally led his troops to help Jinzhou. At this time, the leaders of Jiannu finally decided to give up internal struggle and turn to the outside world.

Of course, only Xiaozhuang is included. She didn't call this name at this time, and it probably won't be used in the future. The little emperor Shunzhi is still a puppet, but the one who brought up the line in the past was Dorgon, now Dorgon's mistress and his biological mother.

The Manchu Jiannu spent his troops to support Songjin, and his materials and supplies were continuously transported to Jinzhou.

Geng Zhongming was just excited about the withdrawal of the Ming army in Jingbei for less than a few hours, and he realized that Ningyuan was defeated, his old enemy Shang Kexi was captured alive, and Wu Sangui and Kong Youde fled together.

The Qing soldiers in Songshan Fort were strictly guarded. At that time, Sun Chengzong and Yuan Chonghuan, the master and apprentice, never dreamed that they had to work hard to hollow out the defense line built by the national treasury, became a barrier for the Qing soldiers to block the Han army layer by layer.
