The rolling wood-rolling stone is one of the ancient city-defense weapons. The working principle is similar to the iron chariot in Yue Quanzhi. It is to build a slope inside the city wall. On the top of the slope, a solid wood log that is as thick as a bucket is fixed with ropes. The surface of the log is filled with triangular iron spikes. As long as the rope that fixes the rolling wood-rolling stone is cut off, the rolling wood-rolling stone will roll down towards the opponent, and the soldiers who attack the opponent will be crushed in front of such rolling wood-rolling stones.

In the era of cold weapons, a small city could be guarded for months or even years. It was because the Huns were rampant in northern China that ancient China invented the city-guarding equipment and the city-guarding system.

Both ends of the rolling wood-rolling stone are fixed with iron locks. When the kinetic energy of the rolling wood-rolling stone is exhausted, the city guards can turn the wheels and pull the rolling wood-rolling stone back to the top of the slope, which can be reused.

Chongfei possesses heavy weapons such as scattering machines to destroy all these wooden rocks. Otherwise, the ants siege would be a suicide.

When it comes to defending the city, the Chinese are the best people in the world who are good at defending the city. The Mongolian army swept the world and was blocked under the city of Xiangyang for 38 years. Even if they used the Hui Hui cannon, they could not break through Xiangyang City. Xiangyang City was eventually lost because the defender turned against him and surrendered.

If Xue Renguo hadn't been angry and attacked, he wouldn't have made such a mistake of underestimating the enemy.

However, the consequences of this mistake were quite heavy. More than a thousand Western Qin soldiers were directly destroyed. Dozens of wooden rocks weighing thousands of pounds were pushed down by the Jingyang Township Warriors. As the wooden rocks roared down, the Western Qin army that was swarming in was knocked down one after another. In just a dozen breaths, the Western Qin soldiers with as many as five or six hundred people on the city wall were no longer alive.

The soldiers of the Western Qin army who were knocked down by rolling wooden rocks or the Jingyang Township Warriors who were accidentally hit were almost no exception, and all turned into a vague flesh and blood.

Xue Renguo did not persist when he looked at this scene. He was also a person who was proficient in military tactics. Although he didn't care about the lives of soldiers, his morale had fallen to freezing point. In addition to increasing casualties, it would be useless to fight again.

The war stopped, and both sides were licking their wounds, accumulating strength, and preparing to make a comeback.

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

The three village chariots he had worked hard to form have now suffered nearly half of their casualties. Among them, 403 were killed and 356 were injured. Even the wounded were included in the group that could maintain combat effectiveness, less than one and a half.

The local savages with so many casualties in Jingyang City were suddenly filled with sorrow and crying.

Since the Western Qin army did not have a catapult, the wounded soldiers were temporarily placed at the foot of the city. Chen Ying came to this temporary wounded soldiers' resettlement camp and felt very heavy.

"Please, give me some fun!" A seriously injured village man whispered like a mouse.

Chen Ying felt like there was something stuck in his throat, which made him feel difficult to breathe.

After carefully checking the injury of the town warrior, Chen Ying couldn't help but frown. The wounded soldier had only one wounded soldier, which was on the outside of the base of his thigh. Although the wound was very long and deep, it was not fatal.

"Life well!" Chen Ying whispered: "You can't kill yourself if you hurt like this. At most one month, you can jump around."

"I can't stop the blood, this kind of injury cannot survive!" The wounded soldier stretched out his bloody hand and touched Chen Ying with difficulty: "Please... please, give me some fun!"

"Mr. Chen, please give me some fun, please!"

The doctor general who treated the wounded soldiers poured a large bag of yellow medicine powder on the wound, and blood kept flowing out, causing the medicine powder to be washed away quickly, and the effect of stopping bleeding was not achieved at all.

Seeing that the bleeding-resistance powder was ineffective, the middle-aged doctor was obviously a little panicked. He changed several kinds of medicine powder again, and even asked the injured soldier to take a few herbs raw, but he still couldn't stop the bleeding. Now the middle-aged doctor was helpless.

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

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

Chen Ying vaguely remembered that traditional Chinese medicine technology was not behind. Hua Tuo had invented traditional Chinese medicine surgery and even proposed to have a craniotomy on Cao Cao. Of course, most of the medical skills were lost after Hua Tuo's death. It has to be said that it was a tragedy.

Chen Ying actually knows medical skills, but he has watched TV and novels and knows that it is not difficult to suture the wound. Anyway, this soldier has been sentenced to death by the doctor. It is his fate to be able to save him, and it is God's will that he cannot save him.

Chen Ying suddenly said anxiously: "Find a needle for me, the big needle for sewing clothes, and thread... hurry!"

At this time, Chen Ying had already established absolute prestige in Jingyang City. After a while, a sweaty village man gave Chen Ying a sewing bag.

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

When the wounded soldier heard this, a dim look appeared in his dim eyes.

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

A sterile environment is needed before the operation to avoid wound infection. Chen Ying did not have that condition at this time, and even the alcohol used for disinfection was unable to be created urgently. At this time, he could only do his best to do his best and leave his will.

Chen Ying took the needle to disinfect the charcoal fire, and at the same time twisted the needle into a hook. After the needle became cold, he passed the thread through the needle. After making these preparations, Chen Ying checked the other party's wound again and found that the tendons inside were not broken. Then he cleaned some foreign objects inside, and finally picked up the needle and began to suture the wound.

Seeing Chen Ying suturing the wound like a stitching clothes, the other soldiers were frightened and retreated. As Chen Ying's suturing speed became faster and faster, the soldier's wound, which was nearly one foot long on his thigh, slowly stopped bleeding. When Chen Ying finally closed his mouth, he left a small mouth so that the blood in the wound could be excreted. The reason why he understood this was that on the one hand, he had learned some first aid knowledge, and was also influenced by some books, films and TV...

After Chen Ying sutured the casualties, he suddenly found that the doctor was still watching Chen Ying sutured the wound.

"May I have your name?"

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

"Oh!" Chen Ying smiled slightly and said, "I didn't expect that we were a family five hundred years ago! Have you remembered this wound suture technique?"

"It's almost done!" Chen Huairen said in confusion: "Dare you ask General Manager Chen, is this... the suture technique original? "

"Where do I have this ability!" Chen Ying said: "This is what I saw in a broken ancient book, and it seems to be created by Hua Tuo.

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

Chen Huairen said: "Including the little old man and four disciples who have not yet mastered, there are eleven people in total!"

Chen Ying said: "Now the general manager has established the Jingyang Township Yong Medical Team. You, Chen Huairen, are the chief medical team of the school, and your grade is tentatively set to be the seventh rank!"

"Thank you, General Manager Chen!" Chen Huairen kowtowed to Chen Ying repeatedly: "Little... I will never let General Manager Chen down!"
