The more than 100 people in front of the Later Jin army that rushed into the gap were hand-to-hand combat soldiers, and more than 200 archers behind them. The distance between the two sides was only more than twenty steps, and the heavy arrows shot at such a close distance could penetrate the armor of the Ming army.

"Rise the shield!" Li Laoer shouted.

The 120 Ming soldiers themselves carried a small round shield, but the small round shield could only protect themselves from the key points such as the face and body, and had no time to care about their arms and legs. So many people picked up large wooden signs from the corpses of Minzhuang on the ground.

The first round of heavy arrows of the Jin army had already shot towards each other. The Ming army standing in front was holding a small round shield in its hands, blocking the arrows that shot towards its face and body. However, more than ten people were shot in their legs and arms and fell down screaming. The small round shield also fell to the ground. The Ming army behind, including Li Laoer and Cao Bianjiao, were exposed to the archers of the Later Jin army.

Fortunately, the Ming army, who picked up the large wooden sign from the ground, had already set up a shield and surrounded a shield wall.

When the second round of arrows of the Jin army shot out, they were blocked by big wooden signs.

To break the shield wall, heavy armored infantry needed to approach the battle. The hand-to-hand soldiers in front of the Later Jin army stepped forward and approached step by step. At this critical moment, Yan Yingyuan yelled: "Brothers, come on!"

More than fifty spears remaining behind them endured the pain, picked up spears from the ground, stood behind the shield wall, and when the Jin soldiers approached about three steps, more than fifty spears pierced out at the same time, overturning the more than ten red-armored soldiers approaching.

Li Laoer, Li Hong, Han Dashan and others were not idle either. They were excellent archers themselves. With the shield wall, the three of them shot a sharp arrow from behind from time to time, specifically to greet the archers behind the Later Jin army. All three of them fired arrows without any slight arrows, and each sharp arrow would take the life of an Later Jin archer.

Cao Bianjiao and Yan Yingyuan were both powerful generals who were skillful in summoning spears. They shot two rounds of arrows, each shot over two Later Jin archers, and immediately thrust the spear and pierced the shield formation.

From time to time, some people from the Ming army behind the shield wall extended their three-eyed guns, aimed at the Later Jin soldiers who were close to each other, ignited the muskets, and knocked down many Jin soldiers who were close to them.

Although there was a shield wall blocking it, the elite Later Jin archers still shot feather arrows from time to time through the gap between the shield and the shield. The Minzhuang spearmen standing behind the shield wall kept getting caught in arrows and fell down screaming.

More and more Later Jin soldiers poured in from the gap. Seeing that Li Laoer and the others were about to stand it, Cao Wenzhao came with more than a thousand people, and finally blocked the gap and drove the Jin army out.

It was already dark, and the Later Jin army suspended the attack, retreated to the camp to rest, and prepared to fight again tomorrow. After this day of attack, Huang Taiji felt that it was much easier to attack this flat formation than to attack the city. More than 100,000 people outside Tongzhou City were the targets of the Later Jin wanted to plunder, and Huang Taiji was unwilling to let go of this big fat piece of meat.

The Ming army from all over the country killed many enemies within one day, but rarely captured them. Li Laoer, who had originally come up to seize weapons and equipment, almost no one was seized. Because when the Later Jin army retreated, the bodies and wounded were taken away by them, and the scattered weapons were taken back by them.

Li Lao Er's brothers only won twenty-five heads, Cao Wenzhao and Cao Bianjiao's uncle and nephew won thirty-two heads, Yang Guozhu won 27 heads, and Yan Yingyuan's Minsheng team won 16 heads.

During the fierce battle on this day, Li Laoer and Sun Chengzong roughly estimated that there were at least 2,000 casualties in the Jin army, and at least more than 1,500 casualties in the Ming people. The Ming army itself suffered more than 1,500 casualties, and more than 300 casualties in the civilian army.

Even more than 600 brothers of Li Laoer himself suffered more than 50 casualties, including 16 who died in battle and were incurred, and the rest could be cured.

Behind the position outside Tongzhou City, Li Laoer asked someone to light a bonfire and set up a large iron pot on the bonfire. Under Li Laoer's command, the civilians poured the snow into the iron pot and burned it into a pot of boiling boiling water.

Then Li Laoer scalded a foot-long short knife and scissors with boiling water, and asked someone to take out the gauze that had been prepared a few days ago. These gauzes were cooked in a boiling water pot a few days ago, and then hung up to dry; there was also high-alcohol wine, which had been prepared a few days ago.

The wounded were all lying in the canvas tent, with braziers filled with charcoal placed in the tent. The charcoal was burning in the brazier, making the tent warm as spring.

Li Lao Er picked up the disinfected short knife and scissors and walked to a brother who was shot in the leg. He first asked the brother to remove the hem of his armor and pants, revealing the injured part.

"Brother, bear with it." Li Laoer comforted the brother.

Then he first disinfected the wound with strong liquor, then picked up a knife to dig out the flesh around the wound, expanded the wound, then pulled out the arrow with barbs, and poured the wine into the wound to clean it. Finally, he poured a small bottle of gunpowder on the wound and lit it with a candle. With a burst of slaps, the gunpowder quickly burned out, and the brother let out a scream of exhaustion, causing a coma. The gunpowder burned, killing bacteria and viruses, and also burned blood vessels and stopped the blood.

"Band it with gauze. The wounds treated in this way can be as short as five or six days or as long as one month." Li Laoer turned his head and said to Cao Bianjiao and others who followed him in.

Before, his own brothers were injured in repeated fierce battles, and they all used this method to save them.

Disinfected knives and scissors can prevent wound infection; applying the wound with strong alcohol can kill bacteria and viruses on the periphery of the wound. After pulling out the arrowhead, clean the wound with strong alcohol can disinfect it, and clean the toxins left in the wound by the arrowhead; finally pouring gunpowder on fire can ignite it, which can completely kill viruses and bacteria and stop the blood.

"General Li Xiao, your method is really effective?" Cao Bianjiao asked incredible.

"Of course it works. I have saved many brothers with this method. If it weren't for this method, my brother would have lost at least two hundred more people."

Afterwards, Li Laoer handed over his treatment of the wounded to Yan Yingyuan and Minzhuang, and also taught the yamen runners, Zaoli and Baizhan who came to help treat the wounded, and asked them to help treat the wounded.

With this kind of disinfection and treatment method, most of the injured can survive.

Of course, Li Laoer is not a real doctor. When he met some of the severely injured Ming soldiers, he was helpless.

The large tent of the Central Army of the Later Jin Dynasty, this is a huge tent, six meters long and three meters high. The fire in the tent made the tent warm as spring. Huang Taiji sat in the middle, and around him were Daishan, Jirhalang, Sahalian, Abatai, Dudu, Ajige, Dorgon, Dodo, Haoge and Yuetuo, Fan Wencheng, Sun Degong, Li Yongfang and other Han ministers sat on the left, and Jijit Chahan, Dai Qing, Hatan, Congor and other Mongolians sat on the right.

In today's battle, in addition to the two yellow flags, all the Jurchen soldiers who fought in the six flags suffered casualties, especially the two white flags had the largest casualties, and more than 20 white armored soldiers and more than 20 red armored soldiers were damaged.
