After all, many people still feel lucky. Taiyuan City has been surrounded many times since Li Keyong, and is still as stable as a mountain.

Moreover, many people firmly believe that the Khitan father will never abandon them.

So, the defenders of Taiyuan City stood on the city wall and watched the Tang army build the long dike bit by bit and intercept the Fen River. This feeling was so uncomfortable.

However, they dare not go out to the city to fight. Most people do not do anything about going but going back.

However, tens of thousands of people were synchronized in the construction of a long dike. Although the speed was very fast, the weather in Shanxi was really hard to figure out. After a while, it started to drizzle.

As mentioned earlier, Taiyuan City is located in the four blocks, with mountains in front, back, left and right. Naturally, the weather changes a lot.

The key is that today's season is summer, and it's the time for heat. The rain that falls not only does not relieve heat, but also makes the air full of stuffy and humid.

Many soldiers were greedy for the cold and took off their clothes. As a result, the rain was soaked in and the wind and cold were caught.

In less than three days, more than a thousand soldiers fell ill in the military camp.

This surprised Li Jia and immediately asked the military police to supervise the guys who took off their straw raincoats without authorization to serve them one by one.

Even so, the hot and cold weather still makes the army lose its troops seriously.

This is still in Shanxi. If it is in Liaodong or the Western Regions, you can imagine how difficult the expeditionary army is.

Fortunately, he was foresighted and recruited a large number of doctors, especially famous doctors like Wang Huaiyin, who even offered secret recipes.

Li Jia naturally won't let these things down.

He asked someone to collect medicinal materials, strictly follow the prescription, and then divide them into finished packets of doses.

If you are not accustomed to the weather and cold, you should drink a few packs first. If it does not work, a doctor will be sent to continue drinking after it comes to work.

To put it bluntly, it means that the medicine is produced in a quantitative manner, and the effect is similar when it is consumed. It is no longer precise treatment, but a large amount of food and fullness.

Not to mention, in this way, although some soldiers died, most of them survived, which was much more rescued than those who took care of them.

Wang Huaiyin originally opposed this because traditional Chinese medicine emphasizes looking, listening, asking and touching. If there is any problem, take medicine directly. If it is not done well, see a doctor. It is really inconsistent with his views.

But, the effect is indeed good.

"Only the army is suitable for this!"

Wang Huaiyin was confused while seeing a doctor.

"It's okay!" He took his veins for a moment and pondered: "Let's rest for a few more days."

"Thank you, Doctor Wang!" The soldiers were very excited. This feeling of security was really good.

"By the way, how many days have your long dike been repaired?"

"It's been seven or eight days, and it's about half of it."

The soldier smiled and said, "I would rather go to the Climbing of the Long Dike than to attack the city. This Taiyuan City is too high and too strong. I don't know how many people will die!"

"Yeah!" Wang Huaiyin nodded and replied: "Yes, I don't know how many people will die. When will this stop!"

The doctor is kind-hearted. Even if he sees too much life and death, his power of war is chilling. Wang Huaiyin restrained his mood and sighed: "I hope Taiyuan can be won as soon as possible!"

"Taiyuan City is not giving up!" Li Jia stood tall on the high ground, looking at Taiyuan City standing among the mountains, and couldn't help but say angrily: "I really don't have the heart to die if I can't die if I don't."

"Why have to force me to take action?"

Looking from a distance, the Fen River in the past has been intercepted and accumulated a huge landslide lake, but the embankment is constantly increasing, in order to accumulate more water and thus have greater power.

There is no doubt that the Fen River is not only the source of life in Taiyuan, but also its life gate.

However, the Northern Han Dynasty was also the last country. After fighting this, it was the Khitan. It had enough mercy, so it was time to use some thunderous anger.

"Come here, people in Taiyuan cannot watch the fun during this period. Take out the stone throwing cart and let Taiyuan City taste the taste."

The emperor sneered.

Immediately, hundreds of stone throwing cars prepared in advance began to be installed and arranged one after another, and then they took materials locally and transported a large amount of stones to Taiyuan City.

Taiyuan City is high in the north and low in the south, so if it attacks, it is a back attack, but for a stone-dropping cart, a city with a height of three feet is no problem at all.

"boom--"

A loud noise woke up the entire Taiyuan City. The defenders on Taiyuan City immediately poked their heads out and saw a small pit breaking out on the thick city wall.

I saw a huge rock lying under the city wall, telling the incident just now.

Immediately, a large number of black shop spots appeared in the eyes of the defenders, and then a little bit of methods, with huge power. It is conceivable that as long as you get a little bit, you will either die or be injured.

Some hit the wall, some fell into the moat, and some entered Taiyuan City directly.

Many Taiyuan people sit at home, and disaster comes from heaven, and family members are ruined by this, and there is no time to shout.

Although there are only a few stones, they still panic about it.

You should know that Taiyuan City is in a condescending terrain, and the city walls are high, and ordinary catapults are not strong enough to enter the city.

Nowadays, the specially improved stone throwing cart of the Tang Kingdom has changed this situation. It has pulleys to help, and it has too much power.

Let me talk about it here that the catapults in ancient China belong to the principle of leverage, without pulleys, and even without wheels, which belong to the on-site buried type.

When we arrived in the Eastern Han Dynasty and the Three Kingdoms, Cao Cao's thunder chariot took a step further and installed the wheels to make it more convenient for marching.

Later, during the Southern and Northern Dynasties, the throwing rod could rotate freely and adjust the direction, which was improved into a cyclone.

By the end of the Song Dynasty, the Mongols brought the repurchase, which is what Li Jia has improved at this time. There was a huge rock behind it, and the throwing rod was loaded with pulleys, which could be pulled down easily, and then put it on, and the stone could naturally eject out.

It is no longer necessary for hundreds of people to pull the rope, pull the end down and release it, this exhausting method is now.

It has greater power and is easier to operate. It is known as the principle and can be easily imitated.

Although the power of hundreds of catapults was tickling for Taiyuan City, it was the later Taiyuan Battle, and hundreds of cannons were bombarded together, and our party also spent several months.

However, the stone throwing cart is not about its power, but about its powerful impact on people's hearts.

For example, after the stone throwing cart was shot, the new Northern Han emperor Liu Jien was frightened, fearing that he would fall next to him if he accidentally did not dare to stay together for a long time.
