After all, there was no explosives in this era, and the earth bomb made of black gunpowder was not very powerful. You should know that the intensity of explosives in later generations was more than 100 times that of black gunpowder! Although the energy contained in explosives is not much higher than that of black gunpowder, the explosives have a shorter time, that is, the speed is faster, and can release all energy in a shorter time, so the power of explosives is far greater than that of black gunpowder.

Although it is only serious injury, in this era, if you are seriously injured, you will be waiting to die. The iron nails installed in ten thousand enemies are all rust iron nails removed from the house and furniture and pierced into the human body. Although it is protected by armor, it is not penetrated deep, but the rust iron nails are similar to the poisonous arrows in this era. The poisonous arrows of the Later Jin army were inserted into the feces before shooting arrows, and they became poisonous arrows. By the same token, if they were stabbed into the body by rust iron, they would soon be infected with the wound and die in pain.

The Later Jin army's siege failed again. The dead Baoyi lifted up the seriously injured Jianzhou Jurchen soldiers and retreated.

The Ming army smashed 50,000 enemies, causing more than 1,000 casualties to the Later Jin army.

In fact, there were far more than one thousand casualties, and at least two thousand casualties. However, according to Lao Nu's nature, that is, Baoyi does not count the human series. This is very similar to the fact that when the US military counted the casualties of the United Nations soldiers in later Korean Wars, the Koreans did not count the human series. The largest casualties of Nan Bangzi were not counted. The result was that the Chinese were far more casualties than the United Nations multinational coalition.

More than a thousand Baoyi was injured by the bombing of ten thousand enemies, and more than two thousand Baoyi was killed and injured in the ant attack before, even the wounded soldiers were not taken care of. The retreating Baoyi only carried the injured Jianzhou Jurchen soldiers back, and no one cared about Baoyi who fell to the ground and wailed, and no one dared to care about them.

If a half-dead coat was brought back, the old slave would definitely have to cut the half-dead coat in order to save food, and the coat that carried a disabled man back would also be implicated, and the old slave might also be killed by the old slave.

How many of those Baoyun died, the old slave didn't feel sorry for him. What he felt sorry for was that more than 2,000 Jianzhou Jurchen soldiers were injured or killed before and after the battle in Kaiyuan.

"Ah! Please give me some fun!" A heart-wrenching scream came.

The old slave hurriedly ran forward and saw that Zhenghuangqi Niu Luezhen Balbu was lying on a stretcher. The cotton armor on his body was covered in blood, and rusty iron nails were densely covered with pieces of wood from a ladder. The sharp wood chip pierced his armor and penetrated his abdomen.

A shaman wizard who was accompanying the army cut open the cotton armor with scissors and wanted to pull the cotton armor apart and perform surgery on Balbu. However, after cutting the cotton armor, he found that the cotton armor was firmly nailed to the muscles by iron nails and could not be removed at all. So the wizard cut it around the wood chip inserted in the abdomen and pulled it open the cotton armor. Only then did he find that there was a big hole in Balbu's abdomen and the intestines could be seen.

After cutting a little more cotton armor, I found that the chain mail inside was densely packed with embroidered iron nails, the whole abdomen was like a horse's nest, and the legs were also densely packed with rust iron nails.

"Return to the Khan King, General Babur's injuries are beyond his control." The shaman saluted the old slave.

"Master, please give me some fun." Balbu cried.

The old slave's face turned pale, gritted his teeth, pulled out the golden knife, stabbed Balbu's heart with one knife, ending his pain.

There were at least 800 Jianzhou Jurchen soldiers carried back outside, and each of them was lying on a stretcher and wailing. The injured were not as severe as Babul, but they were nailed into a horse's nest with embroidered iron. With the medical technology of this era, it was hopeless.

"Ama, let's withdraw our troops and can't fight anymore. We can't waste our warriors' lives here in vain." Huang Taiji stepped forward and knelt on the ground and beat him a thousand times.

Before the old slave could reply, Dai Shan said angrily: "Eighth brother, if we withdraw our troops now, will the sacrificed warriors be in vain?"

Huang Taiji said: "Da Beile, our army suffered heavy losses to attack a small Kaiyuan city, and our army has insufficient food and supplies. If we continue to attack and the army is interrupted, once the morale of the army is shaken and defeated, then all the efforts of Khan Ama over the years will be wasted! I am afraid that those Haixi people will betray us! Even the Korqin people will leave us!"

"Eighth brother! You..." Dai Shan wanted to say something else.

Who knew that the old slave interrupted him: "Daishan, the eighth prince said it makes sense. If we forcefully attack Kaiyuan, our army would probably be defeated! Yang Hao and Li Rubai considered that their black hats could no longer be worn, and if our army continued to siege here, and when the food and grass were exhausted, the soldiers could not even pick up their weapons. How can we resist the attack of the barbarian army? It would be better to give up Kaiyuan for the time being and turn to attack Tieling!"

Lao Nu is naturally a hero of a generation and has a very accurate judgment on the situation. Otherwise, he would not have raised his army with thirteen pairs of armor and has almost no defeat yet.

This time I was frustrated in Kaiyuan. If I should admit my failure, I would admit my failure. There is nothing to be ashamed of. I pretended to be a slave in Li Chengliang's family, and then I went to the Tong family to be a son-in-law. I pretended that my grandson could pretend to be able to pretend. So what if I admit my failure once? If I can't beat me, I will leave. There is no need to fight to the death.

However, the old slave was still unwilling to leave like this, and had to take back most of the dead Jianzhou Jurchen soldiers' corpses. Just send Baoyi Aha to do this.

Many Ming troops had already come down from the city and were harvesting their heads easily and happily. Whether it was the Jianzhou Jurchens, Han people, or Korean people, as long as they were the heads of the rat-tailed braids, they were very valuable to send them back to the capital. The Wanli period was not as rich as the later Chongzhen period. After the three major expeditions, Wanli was richer than Chongzhen. The soldiers should have earned money for making contributions. Wanli would not have a penny of the money they deserved. Unlike Chongzhen, they were so poor that they could not even pay the military pay for the royal army, and there was no money to recruit thieves.

The Later Jin army sent Baoyi to take back the bodies of the Jianzhou Jurchen soldiers, but in the end they were killed by many bows, arrows and muskets on the top of the city, and more corpses were dropped. Finally, most of the bodies of the Jianzhou Jurchen soldiers were brought back.

"Jiannu has withdrew his troops! Jiannu has withdrew his troops!" The cheers of the Ming army and civilians sounded from the city.

The Later Jin army and the Korchin cavalry lined up outside the camp to guard the guard. The Baoyi Ahas packed up their tents, pulled out the wooden fences, put all the things they could take away into the car, and set fire to burn the ones that could not be taken away. Then the Great Jin army retreated from the original in an orderly manner. Even the failed retreat still maintained the momentum of an elite force, lined up in an orderly manner, with cavalry protection on both wings, heavy infantry riding horses in the middle, and baggage vehicles in the middle.

Gao Shixin stood at the top of the city wall and looked at the army of Later Jin that was gradually moving away. One thing he thought of was that the Later Jin army would probably attack Tieling!

Originally, the old slave wanted to take Kaiyuan and take Kaiyuan. On the one hand, it could solve the food problem, and on the other hand, it opened up the connection between the Later Jin and the Mongols. According to historical records, after Kaiyuan was lost, the Later Jin obtained huge amount of wealth and manpower, and the livestock, food and property were transported by the Later Jin for three days but not transported.

The Later Jin Dynasty conquered Kaiyuan, had the ability to unify the Jurchens, and had the conditions to communicate with Mongolia.

Because of Gao Shixin's trick, the old slave was forced to give up Kaiyuan and attack Tieling first and take down Tieling. Kaiyuan would become an isolated city.

"Jiannu did not go home, they must have gone straight to Tieling!" said Gao Shixin.

"We can only rely on the defenders of Tieling. We have too few people, so it is still acceptable to defend the city. If we go out of the city to pursue Jiannu, we will probably not only have to be defeated, but even Kaiyuan will be lost." Malin sighed helplessly.

Gao Shixin replied: "The city of Tieling is as solid as a golden soup. If there is no Jiannu in the city, it will be difficult for Jiannu to break through. One thing I only worry about is that Jiannu is everywhere in the cities in Liaodong! Through the fierce battles over the past few days, it can be seen that Jiannu is actually not good at siegeing the city, and what they rely on is nothing more than meticulous work."
