Listen to Emperor Wei’s words.

Qin Yu pointed to the concrete wall not far away against the red wall and pondered: "Your Majesty, that's right there."

Emperor Wei looked in the direction Qin Yu pointed, and was stunned at first, then his face darkened.

Qin Yu turned into this look in the good palace wall.

Qin Wenyao, Lu Jianping and others' expressions also changed. Emperor Wei was most annoying to others in the palace.

But I know it was done by Qin Yu.

Emperor Wei still suppressed his anger and said calmly: "That's the new material you made by your good son-in-law?"

Qin Wenyao: "???"

Lu Jianping: "???"

99: "???"

Everyone looked at Emperor Wei with a confused look on their faces. They thought Emperor Wei would get angry, but they didn't expect to even let go of a fart.

Is this too double standard?

Qin Yu did not notice the change of everyone's faces, nodded slightly, and said lightly: "Yes, this material is called concrete, which 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 using earth rammed and glutinous rice water as adhesive walls.

Looking at the crossbow and catapults beside him.

Emperor Wei raised his eyebrows and said in surprise: "Even the crossbow and the catapult are ready. It seems that 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 great confidence.

Qin Yu smiled indifferently, "Do you have confidence? Will your Majesty know if you have tried it?"

“Okay.”

Emperor Wei nodded and looked at Meng Zhan beside him, "Push the crossbow to a four hundred steps and attack the concrete wall."

"Yes, Your Majesty." Meng Zhan responded, and then led several Yulin Guards to prepare.

Not long.

After loading four long spear-sized crossbows, they were pushed to the designated position.

Emperor Wei, Qin Wenyao and others couldn't help but get entangled.

On the one hand, they hoped that concrete could really strengthen the city defense several times as Qin Yu said, but they did not want Qin Yu to take Xiao Nan to the border to take risks.

Xiao Nan rubbed his hands, walked forward and said excitedly: "I will launch it myself."

To him, these siege equipment have a natural attraction.

Qin Yu looked light and calm, and he was very confident in concrete.

at the same time.

Xiao Nan began to adjust the angle of the crossbow, and the Yulin Guards on the side began to stir up the bowstring.

Everyone's eyes fell on the crossbow.

moment.

The bow string that was pulled on the crossbow was instantly ejected.

Four crossbow arrows headed straight for the concrete wall that was four hundred steps away.

Lightning and fire.

Four crossbow arrows shot hard onto the concrete.

Bang, bang....

The moment the crossbow arrow touched the concrete wall, four crossbow arrows broke in response to each other.

The crossbow arrows that emitted a cold light only left small potholes on the concrete wall.

See this scene.

Emperor Wei, Qin Wenyao and Meng Zhan all showed shocked expressions.

Although it is winter now, it will make the crossbow arrows crisp and make the walls stronger, even with these objective factors, the solidity of the concrete wall is still self-evident.

"This...is this too exaggerated? The crossbow arrows were broken, leaving only a small pit?"

"No wonder the prince-consort is so confident. The solidity of this concrete wall is really not something that can be blown out."

"Tsk tsk tsk... The production of the Prince Consort must be a fine product. If concrete is used to reinforce the city defense, the degree of solidity will be increased several times."

"Awesome! My brother-in-law is awesome!!!"

......

Everyone was amazed at the concrete wall that was more solid than imagined.

Emperor Wei also exclaimed, "Must... the concrete wall is so strong!?"

In fact, he was still very confident in Qin Yu because he knew that Qin Yu never fought a war that he was unsure of.

But Emperor Wei really didn't expect that the solidity of the concrete wall would be so hard!

Everyone was shocked.

Qin Yu looked calm and composed, all of this was in his plan.

Immediately afterwards.

Emperor Wei looked at Meng Zhan and hurriedly said, "Hurry! Pull the catapult to me quickly! I want to see how strong the concrete wall can resist the catapult!"

The words are over.

Several Yulin Guards pushed the catapult forward.

Xiao Nan picked up the sledgehammer and prepared to be a launcher.

After the catapult is in place.

The Yulin Guard picked up a huge rock and put it into the shot on the thrust tool, and then began to stir the bowstring.

Xiao Nan spat twice in his palm, then rubbed his hands, swung the hammer, and smashed it hard towards the trigger of the stone caster.

Bang!

The sledgehammer hit the trigger hard.

The shot instantly ejected, and the boulders inside roared towards the concrete wall.

Boom...

The huge rock hit the concrete wall hard, and the walls were trembling with huge impact. The huge impact force and the cold winter made the huge rock brittle, causing the huge rock to shatter in an instant.

I saw that there was still a pothole left on the concrete wall, without any cracks.

At such a close distance, if it hits the city wall, it will splash gravel on the city wall and the blue bricks will not be cracked.

So I looked at the concrete wall that was far stronger than the city wall.

The Wei Emperor and his group were all staring wide, dumbfounded and unbelievable.

They really couldn't figure out how Qin Yu made such a magical material.

Is this clearly a solid material that can only be used in the walls of the Tiangong Palace?

At the same time, they also shocked Qin Yu's wide range of fields of exploration, and he was able to get anything done.

In the horrified eyes of everyone.

Emperor Wei hurriedly waved his hand, "Let it go again! Let it go again!"

Today he wants to see where the limit of concrete walls is.

Immediately afterwards.

Whoosh, whoosh, whoosh...

Titanium rocks roared towards the concrete wall in the distance under the launch of the catapult.

Emperor Wei felt that he was not satisfied and asked Yulinwei to launch a crossbow.

In just a moment, the concrete walls were filled with potholes, but there were still no traces of cracks.

But this is also because the boulder did not fall on the same location as the concrete wall.

After all, it is impossible to shoot accurately with a stone caster.

The probability of two huge rocks falling in the same position is slim.

After the concrete wall was bombarded by catapults and crossbows, it was already dilapidated and mottled.

But these are obviously small scars and do not cause any fatal damage to the wall.

At this time, everyone finally had a clear understanding of the solidity of the concrete wall.
