Qin Yu pointed to the concrete wall attached to the red wall not far away and muttered: "Your Majesty, it's right there."
Emperor Wei looked in the direction pointed by Qin Yu. He was stunned for a moment, and then his face darkened.
The good palace wall was turned into this look by Qin Yu.
The expressions of Qin Wenyao and Lu Jianping also changed. Emperor Wei usually annoyed others the most when it came to misbehaving in the palace.
But I knew it was Qin Yu who did it.
Emperor Wei still suppressed his anger and said calmly: "Well, this is the new material you created, my good son-in-law?"
Qin Wenyao: "???"
Lu Jianping: "???"
99: "???"
Everyone looked at Emperor Wei in confusion. They thought Emperor Wei would get angry, but they didn't expect that he didn't even fart.
Isn’t this too much of a double standard?
Qin Yu didn't notice the change in everyone's expressions, nodded slightly, and said calmly: "Yes, this material is called concrete, and it is extremely strong. There are crossbows and catapults here. Your Majesty can try the strength of concrete."
Qin Yu is still very confident about concrete, which is definitely much stronger than a city wall made of rammed earth and glutinous rice water as a binder.
Looking at the crossbows and slings on the side.
Emperor Wei raised his eyebrows and said in surprise: "Even the crossbow and sling are ready. It seems you are very confident!"
Qin Wenyao, Lu Jianping and others also looked at Qin Yu in surprise.
They didn't know where Qin Yu got such confidence.
Qin Yu smiled calmly, "Wouldn't your Majesty know if you are confident or not after you try it?"
"That's fine."
Emperor Wei nodded and looked at Meng Zhan aside, "Advance the crossbow to the 400-step position and attack the concrete wall."
"Yes, Your Majesty." Meng Zhan responded, and then led several Yulin guards to start preparations.
Not long after.
Four crossbows as thick as spears were loaded and pushed to the designated position.
Emperor Wei, Qin Wenyao and others couldn't help but get entangled.
On the one hand, they hope that concrete can really strengthen the city defense several times as Qin Yu said, but they do not want Qin Yu to take Xiao Nan to the border adventure.
Xiao Nan rubbed his hands, walked forward, and said excitedly: "I will launch the launch myself."
These siege equipment have a natural attraction for him.
Qin Yu had a calm expression on his face and was very confident in concrete.
at the same time.
Xiao Nan began to adjust the angle of the crossbow, and the Yulin Guardsmen on the side began to stir the bowstring.
Everyone's eyes fell on the crossbow.
moment.
The fully-stretched bowstring on the crossbow ejected instantly.
The four crossbow arrows went straight to the concrete wall 400 steps away.
The lightning room.
Four crossbow arrows hit the concrete hard.
Bang, bang...
The moment the crossbow arrows touched the concrete wall, there were a few "clicks" and the four crossbow arrows broke in unison.
The crossbow arrows, which exuded cold light, only left small craters on the concrete wall.
See this scene.
Emperor Wei, Qin Wenyao and Meng Zhan all showed shocked expressions.
Although it is winter, which will make the crossbow arrows crisper and make the wall stronger, but even with these objective factors, the solidity of the concrete wall is still self-evident.
"Isn't this too exaggerated? The crossbow arrows were all broken, leaving only a small crater?"
"No wonder the prince-in-law is so confident. The strength of this concrete wall is really not something that can be predicted."
"Tsk tsk tsk... The product produced by the Prince Consort must be of high quality. If concrete is used to reinforce the city defense, the strength will be increased several times."
"Awesome! My brother-in-law is an awesome person!!!"
...
Everyone looked at the concrete wall that was unimaginably strong and marveled.
Emperor Wei was also amazed, "Concrete walls... are actually so strong!?"
In fact, he still has great confidence in Qin Yu, because he knows that Qin Yu never fights an uncertain battle.
But Emperor Wei really didn't expect that the solidity of the concrete wall was so shockingly hard!
Everyone was shocked.
Qin Yu had a calm expression on his face, all this was in his plan.
Immediately afterwards.
Emperor Wei looked at Meng Zhan and said hurriedly: "Quick! Bring me the catapult! I want to see how strong the concrete wall is against the catapult!"
The words fell.
Several Yulin guards pushed the catapult forward.
Xiao Nan picked up the sledgehammer and prepared to be the shooter.
After the catapult is in place.
The Yulin Guardsman picked up a boulder and placed it in the slingshot, and then began to stir the bowstring.
Xiao Nan sighed twice into the palm of his hand, then rubbed his hands, picked up the sledgehammer, and hit the trigger of the catapult hard.
Bang!
The sledgehammer hit the trigger hard.
The shot ejected instantly, and the boulder inside roared towards the concrete wall.
Boom.....
The boulder hit the concrete wall hard, and the wall trembled with the huge impact. The huge impact force and the severe cold in winter made the boulder brittle, causing the boulder to shatter instantly.
I saw that there was still only a pothole left on the concrete wall, without any cracks.
If it were to hit the city wall at such a close distance, gravel would be scattered all over the wall and the blue bricks would be cracked.
So I looked at the concrete wall, which was far stronger than the city wall.
Everyone in Emperor Wei's eyes widened, dumbfounded and in disbelief.
They really couldn't figure out how Qin Yu came up with such magical materials.
This is obviously a solid material that can only be used for the walls of Tiangong, right?
At the same time, they were also shocked by Qin Yu's wide range of fields, and he could handle everything with ease.
In the horrified eyes of everyone.
Emperor Wei waved his hand hurriedly, "Let it go again! Let it go again!"
Today he wanted to see where the limits of concrete walls were.
Immediately afterwards.
Whoosh, whoosh, whoosh...
Huge boulders roared towards the concrete wall in the distance under the launch of the catapult.
Emperor Wei thought it was not enough, so he asked the Yulin Guards to start the ballista.
In just a few moments, the concrete wall was filled with potholes, but there were still no signs of cracks.
But that's also because the boulder didn't land in the same spot as the concrete wall.
After all, it is impossible to shoot accurately with a sling.
The probability of two boulders falling on the same location is extremely slim.
After being bombarded by catapults and crossbows, the concrete walls were already dilapidated and mottled.
But these were obviously minor injuries, and they did not cause any fatal damage to the wall at all.
At this time, everyone finally had a clear understanding of the strength of the concrete wall.
Wei Huang was breathing rapidly and excited, walking towards the concrete wall with small steps.
