Rolling wood and stone is one of the ancient weapons used to defend the city, and its working principle is similar to that of the iron block in the biography of Yue Quan. It is to build a slope on the inner side of the city wall, and on the top of the slope, a solid log as thick as a bucket is fixed with ropes, and the surface of the log is filled with three-edged iron thorns.

In the era of cold weapons, a small city could be defended for months or even years, because the Xiongnu raged in northern China, so that ancient China invented the city defense equipment and city defense system.

The left and right ends of the rolling wood are fixed with iron locks, and when the kinetic energy of the rolling wood is exhausted, the defending soldiers can turn the wheels and pull the rolling wood back to the top of the slope, which can be reused.

Chongfei has heavy weapons such as trebuchets, and destroys all these rolling logs and stones, otherwise it will be suicide to attach ants to attack the city.

When it comes to defending cities, the Chinese are the best people in the world at defending cities. The Mongol army, which swept the world, was blocked under the city of Xiangyang for 38 years, and even if it used the so-called return artillery, it failed to break through the city, and the city was finally lost because the defenders surrendered to the army.

If it weren't for Xue Renguo's anger and attack, he would not have made such a mistake of underestimating the enemy.

However, the consequences of this mistake are quite devastating. directly buried more than 1,000 soldiers of the Western Qin Army. Dozens of rolling wood stones weighing thousands of catties were pushed down by Jingyang Township Yong, and as the rolling wood and stones roared and rolled down, the swarming Western Qin troops were knocked down one after another, and in just a few breaths of time, the Western Qin soldiers who poured up to five or six hundred people on the city wall were no longer alive.

Those soldiers of the Western Qin Army who were knocked down by rolling logs and rocks or Jingyang Xiangyong who were accidentally hit by almost no exception, all turned into a blur of flesh and blood.

Xue Renguo looked at this scene and did not insist, he is also a person who is proficient in the art of war, although he does not care about the lives of soldiers, but his morale has fallen to the freezing point, except for trying to increase casualties, it is useless to fight again.

The war stopped, and both sides were licking their wounds, gathering strength and preparing for a comeback.

Just as he was cleaning the battlefield on the city wall and treating the wounded soldiers, Chen Ying was almost crying.

The three township brave regiments he painstakingly formed are now suffering nearly half of the casualties. Of these, 403 were killed and 356 were wounded, less than one and a half regiments, including the wounded, who could maintain their combat effectiveness.

The townsfolk who suffered so many casualties in Jingyang City suddenly mourned all over the wilderness and cried.

Since the Western Qin army did not have trebuchets, the wounded soldiers were temporarily placed at the foot of the city. Chen Ying came to this temporary camp for the resettlement of wounded soldiers, and his heart was very heavy.

"Please, give me a good time!" A badly injured villager let out a moan like a moan.

Chen Ying felt like something was stuffed in his throat, making him feel like he was having trouble breathing.

After carefully examining the injury of this Xiang Yong, Chen Ying couldn't help frowning, there was only one wounded soldier of this wounded soldier, on the outside of the root of the thigh, although the wound was very long and deep, but it was not fatal.

"Live well!" Chen Ying persuaded in a low voice: "If you have an injury like this, you will die, at most a month, and you will be able to jump around." ”

"I can't stop the bleeding, I can't survive this injury!" The wounded soldier stretched out his hand covered with blood and struggled to touch Chen Ying: "Please...... Please, give me a good time! ”

"Manager Chen, give me a good time, please!"

Lieutenant General Lang, who treated the wounded soldiers, poured a large bag of yellow powder on the wound, and the blood continued to flow out, so that the powder was quickly washed away, and the effect of stopping bleeding could not be achieved at all.

Seeing that the medicine powder to stop bleeding was ineffective, this middle-aged man was obviously a little flustered. After changing a few kinds of medicinal powders again, and even letting the wounded soldier eat a few herbs raw, it still couldn't stop the bleeding, and the middle-aged doctor was a little helpless.

Zhang Huaiwei said: "Whether you can survive this kind of injury depends on God's will." Don't waste time, go and save the others! ”

"Slow, I have a way to stop the bleeding!"

Chen Ying vaguely remembered that the technology of traditional Chinese medicine was not backward, Hua Tuo had already invented traditional Chinese medicine surgery, and even proposed to give Cao Cao a craniotomy. Of course, after Hua Tuo's death, most of his medical skills were lost. I have to say it's a sad one.

Chen Ying actually doesn't know how to heal, but he has watched TV and read novels, and knows that it is not difficult to suture wounds. Anyway, this soldier has been sentenced to death by Lang Zhong, and it is his creation to be able to save him, and it is also the will of God that he cannot be saved.

Chen Ying suddenly said urgently: "Find me a needle, the kind of big needle for sewing clothes, and thread...... Fast! ”

At this time, Chen Ying had already established absolute prestige in Jingyang City, and after a while, a sweaty villager replaced the sewing kit with Chen Ying.

Looking at the wounded soldier's sloppy eyes, Chen said urgently: "I have a way to stop the bleeding, you can't die!" ”

When the wounded soldier heard this, a gleam appeared in his dark eyes.

Chen Ying boiled the thread in boiling water, and then found one with lime water to wash his hands.

A sterile environment is required before surgery to avoid wound infection. Chen Ying didn't have that condition at this time, and he couldn't even make alcohol for disinfection urgently, so he could only do his best and obey the fate of heaven at this time.

Chen Ying took the needle to detoxify it on the charcoal fire, and at the same time twisted the needle into a hook, and only then did the silk thread pass through the needle after the needle cooled. After making these preparations, Chen Ying checked the other party's wound again, found that the tendons and veins inside were not broken, and then cleaned out some foreign bodies inside, and finally picked up the needle and began to stitch up the wound.

Seeing Chen Ying sew up his wounds like sewing clothes, the other soldiers were also frightened and retreated. As Chen Ying's stitches became faster and faster, the soldier's thigh, a wound nearly a foot long, slowly stopped bleeding. When Chen Ying finally closed his mouth, he deliberately left a small opening so that the bruises in the wound could be discharged, the reason why he understood these was that on the one hand, he had learned some first-aid knowledge, and on the other hand, he was also influenced by some books, movies and television......

After Chen Ying finished stitching up the casualties, he suddenly found that this Lang Zhong was still watching Chen Ying stitch up his wounds.

"What's your name?"

"Little ...... Little old man Chen Huairen! Chen Huairen was shocked by Chen Ying's method of stitching up the wound, and it took him a long time to come back to his senses.

"Oh!" Chen Ying smiled slightly: "I didn't expect that we were a family five hundred years ago!" Do you remember this wound suturing technique? ”

"Almost!" Chen Huairen said suspiciously: "Dare to ask Manager Chen, is this ...... Is the suture an original creation? ”

"Where do I have the ability to do this!" Chen Yingdao: "This is what I saw on a broken ancient book, which seems to have been created by Hua Tuo.

By the way, how many Langzhong are there in the city now? ”

Chen Huairen said: "Counting the little old man and the four apprentices who have not yet graduated, there are eleven people in total!" ”

Chen Yingdao: "Now the general manager has established the Jingyang Township Yong Medical Team, and you Chen Huairen is the chief of the medical team of the school, and the grade is tentatively set at the seventh grade!" ”

"Mr. Xie Chen, take care of love!" Chen Huairen kowtowed to Chen Ying again and again: "Little ...... The humble duty will never disappoint the high expectations of Mr. Chen! ”

"You teach this suturing technique to others, and use this method to treat those wounds that are difficult to stop bleeding!" Chen Yingdao: "Stitch up the wound, then apply the medicine according to the original prescription, and boil some medicine to replenish blood and dissolve stasis, now the weather is not hot, the wound is not easy to inflame, as long as the wound is not inflamed, it should be fine for a period of time!" ”
