The First Happy King of Zhenguan in the Tang Dynasty

Chapter 331 blew it up
Sometimes people are blind creatures, just like those old people who buy insurance products in modern times. Those things they buy are not necessarily useful, and they may not really eat them all.

But this thing 'everyone agrees', so they started to buy it blindly, spent all their savings for many years, and ended up having a lot of trouble with the children at home, but in fact the things they bought It's of no use to myself.

The same is true for Cheng Yaojin and Changsun Wuji. Seeing how strong the concrete wall is, no matter whether it is useful for their own home or not, they think that they will use it to repair the courtyard wall as soon as their heads get hot.

Of course, Li Muyun has no objection to this kind of thing. Anyway, whoever takes the money, even if they don't take it themselves, the money will come from the court. For him, a construction worker, it is beneficial One harm.

However, when the two old guys Cheng Yaojin and Changsun Wuji were talking to each other, there was another "squeaky" sound, which attracted everyone's attention.

Li Muyun naturally also heard the sound, and turned his head to realize that at some point, the trebuchet that was placed aside just now had been slowly pulled away and a stone the size of a human head had been placed on it. To enter the launch phase.

It's just a wall, so what?

Looking at the trebuchet, Li Muyun had to admire Li Shimin's persistence, he was indeed an emperor, his unrelenting drive to achieve his goal was really unconvincing.

There was a sound of "咻", before Li Muyun could react, the stone on the trebuchet flew up and smashed towards the vacated wall.

It has to be said that the damage caused by the trebuchet is indeed much stronger than that of the eight-ox crossbow. In the splash of gravel, everyone can clearly see that a place the size of a human head was smashed into fine lines on the wall.

"Go up to the car, I have nothing to do with this broken wall today!" The guy who was directing at the side was also a little hairy. He tore off the hat on his head and threw it on the ground. On the one hand, he pushed the cart up just in case.

Chongche, in fact, has an extremely simple structure. It is a wooden frame with a few wheels on the bottom, and a rough log with two people hugging it hanging on the frame above.

Generally speaking, this thing is used to impact the opponent's city wall or city gate. After dozens of people push it to the bottom of the city, they gather the strength of everyone to pull the rope tied to the end of the log, pull the log up, and then let go suddenly. Under the action of gravity, the log will hit the wall or gate.

If you can't understand it, you can imagine the wooden pillar that monks use to strike the bell. The usage of punching the car is actually the same as it.

Li Muyun looked at Yu Chigong who had thrown away his hat, and was speechless for a moment. No wonder the voice of the guy commanding the bed crossbow and the catapult was familiar, so it turned out to be this guy who was born in iron.

But now it seems that this is not the time to talk about this. The walls of the palace withstood the attacks of the eight-ox crossbow and the catapult. Everyone present was very curious whether the walls could withstand the attack of the charging car.

Li Jing, Li Ji, Cheng Yaojin, and so on, some military generals have realized the importance of this concrete wall at this time, and one or two followed Yu Chigong to join them, squeezing all the civilian officials who were watching the heat. side.

Li Shimin, the emperor of the Tang Dynasty, was actually quite nervous. Although he was mentally prepared for the strength of the concrete wall, he was still taken aback just now.

You know, this wall is only three feet thick, and it has withstood the attacks of bed crossbows and catapults one after another. If this thing is used on the city wall, who else can break the city of Datang?

Not to mention that the construction speed of this thing is almost unimaginable. The long section of the palace wall was basically completed in only half a month. This speed is almost beyond everyone's imagination.

The construction speed is fast and the defense strength is high. What else is more suitable for building a city wall than this thing?If all the city walls of the Tang Dynasty were replaced with this thing, or if a city was built on the grassland with this thing, it would have an incomparably great effect on strengthening the Tang Dynasty's rule over Mobei.

"Boom, boom, boom..." The cart was finally transported into place, and under the operation of a group of imperial guards, it hit the newly built wall again and again.

But to everyone's surprise, the wall that they thought should be able to withstand three or four impacts unexpectedly withstood the continuous impact of the car, except that some gravel was constantly splashed everywhere. After the rest of the impact, the wall didn't seem to have suffered any significant damage.It's just that the soil layer under everyone's feet was a little loose, and with the impact of the car, the looseness became more and more severe.

What are the properties of cement structures?Very strong against stress!If some iron bars and the like are added inside to enhance its stretchability, it becomes a typical iron bar concrete. How can this kind of thing used to prevent artillery attacks during wars in later generations be knocked and sucked? It can be done.

Li Muyun didn't think that these people could smash a one-meter-thick iron bar concrete with wooden tools, at least he didn't believe that they could finish this matter within half an hour.

And if it takes more than half an hour, no, even now, the wall has basically withstood the test, even if the picky emperor comes, he can't say a word of no. It can be seen in a group of people.

Of course, the people around Li Muyun did not include Yu Chigong and others. These Tang Wu lunatics had already developed an interest in the wall, and it seemed that they would not rest until the wall was broken down.

But the wall is completely one piece, and there are iron bars in the middle, so it is not so easy to smash it completely. Finally, after countless times of smashing, the Wu lunatics of Datang all realized the iron bars in the wall. When it came to the fact that the wall could not be completely destroyed, those forbidden soldiers who were about to be paralyzed were spared.

At this time, it was past noon, and everyone had been busy around the wall for nearly an hour and a half. Seeing that everyone had given up, Li Shimin took a deep breath, and said to Yu Chigong who was standing aside and staring at the wall with gritted teeth: "Jingde, go find some gunpowder and blow it up for me!"

fried it?It's easy to say, the corners of Li Muyun's mouth twitched slightly, iron bars and concrete, can it be blown up by earth or gunpowder?If it is modern explosives, it is almost the same, so His Majesty the emperor is destined to be busy for nothing.
