People are sometimes a kind of blind creature, just like the elderly people who buy key products in modern times, they don't necessarily buy those things that are useful, and they don't necessarily actually eat them all.
But everyone said it was good, so they began to buy it blindly, spending all their savings for many years, and finally having a very unpleasant quarrel with the children of the family, but in fact the things they bought were of no use to themselves.
Cheng Yanjin and the eldest grandson Wuji are the same, seeing that the concrete wall is so strong, they don't care if their home is useful or not, and as soon as their heads are hot, they think that they will also use this thing to repair the courtyard wall.
Of course, Li Muyun has no objection to such a 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, there is no harm in it.
However, just when Cheng Yanjin and Eldest Sun Wuji were talking to each other, another squeaky sound came, attracting everyone's attention.
Li Muyun naturally heard this voice, and turned his head to find that he didn't know when, the trebuchet that was placed on the side just now had been slowly pulled apart, and the stone the size of a human head had been loaded, and it looked like it was about to enter the launch stage.
It's just a wall, as far as that's concerned Li Muyun looked at the trebuchet and had to admire Li Shimin's persistence, he was really the one who became the emperor, and this momentum that did not achieve the goal was really unconvincing.
There was a "boom" sound, and before Li Muyun could react, the stones on the trebuchet had already flown up and smashed against the wall that had been vacated.
I have to say that the damage caused by the trebuchet is indeed much stronger than that of the Eight Ox Crossbow, and in the splash of rubble, everyone can clearly see that a place the size of a human head on the wall has been smashed out of fine lines.
"Get on the rushing car, Lao Tzu has no way to break this wall today" The guy who was commanding on the side was also a little hairy, ripped off the hat on his head and threw it on the ground, and scolded and commanded a group of forbidden troops to push the rushing car that was prepared on the side in case of emergency.
In fact, the structure of the car is extremely simple, it is a wooden shelf with a few wheels underneath, and on the upper shelf hangs a rough log about two people hugging.
This thing is generally used to impact the opponent's city wall or city gate, after being pushed by dozens of people to reach the city, gather the strength of everyone to pull the rope tied to the tail of the log, pull the log up, and then suddenly let go, under the action of gravity, the log will crash into the city wall or city gate.
If you can't understand it, you can imagine that the wooden pillar used by the monks to hit the bell, the use of the car is actually the same as it.
Li Muyun looked at Wei Chigong who had lost his hat, and was a little speechless for a while, no wonder he had always felt that the voice of the guy who commanded the bed crossbow and trebuchet was a little familiar, it turned out to be this guy who was born in iron.
However, now does not seem to be the time to talk about this, the walls of the palace have withstood the attacks of the crossbows and trebuchets, and everyone present is very curious whether the walls can withstand the attacks of the rushing cars.
Li Jing, Li Ji, Cheng Yanjin, and some other military generals had already realized the importance of this concrete wall at this time, and one or two of them also followed Wei Chigong up, squeezing aside all those civil officials who were looking at the heat.
Li Shimin, the emperor of the Tang Dynasty, was actually quite nervous, although he had a certain psychological preparation for the strength of the concrete wall, but 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 the Tang Dynasty Not to mention that the speed of construction of this thing is almost unimaginable, and the wall of the palace has been basically completed in only half a month, which is almost beyond everyone's imagination.
The construction speed is fast, the defense strength is high, what is more suitable for building the city wall than this thing, if all the walls of the Tang Dynasty are replaced with this thing, or use this thing to build a city on the grassland, this will play a great role in strengthening the Tang Dynasty's rule in Mobei.
The "dong dong dong" rush car was finally transported to its place, and under the operation of a group of forbidden army soldiers, it hit the newly built wall again and again.
But to everyone's surprise, the wall, which they thought should be able to withstand three or four hits, actually withstood the constant impact of the rushing cars, except for the continuous splashing of some rubble, after more than ten impacts, the wall did not seem to have suffered any particularly major damage.
It's just that the soil layer under everyone's feet is slightly loose, and with the impact of the rushing car again and again, the loosening is getting more and more serious.
What are the characteristics of the cement structure, the pressure resistance is particularly strong, if you add some iron bars and the like to it, strengthen its stretchability, then it becomes a typical iron bar concrete, this kind of thing used to prevent artillery attacks in the war period of later generations, how can it be done by knocking and smacking.
Li Muyun didn't think that these people could smash a meter-thick iron bar of concrete with wooden tools, at least he didn't believe that they could do it in half an hour.
And if it is more than half an hour, no, even now, this wall can basically be regarded as withstanding the test, even if the critical emperor comes, he can't say half a word, which can be seen from the group of people around him.
Of course, the people around Li Muyun did not include Wei Chigong and others, these Tang Dynasty martial arts maniacs had already become interested in the wall, as if they would not rest if they didn't smash the wall.
But the wall is completely integrated, and there are iron bars connected in the middle, how can it be so easy to completely smash it, and finally after smashing it I don't know how many times, the martial arts maniacs of Datang all realized the fact that they could not completely destroy this wall after discovering the iron bars in the wall, and let go of those forbidden troops who were about to be paralyzed.
At this time, the time had passed noon, and everyone had been busy around the wall for nearly an hour and a half, Li Shimin saw that everyone had given up, took a deep breath, and said to Wei Chigong, who was standing on the side and gritting his teeth and staring at the wall: "Jingde, go find some gunpowder and blow it up for me."
Blowing it up is easy to say, the corners of Li Muyun's mouth curled slightly, iron and concrete, is that earth gunpowder capable of exploding If it is modern explosives, it is almost the same, so His Majesty the Emperor is destined to work in vain
