Datang's free and easy concubine

Chapter 37 Surprise

Everyone looked regretful, Su Cheng didn't change his face, and smiled slightly: "Of course it won't work with bricks alone, isn't there cement?"

Everyone's eyes turned to the pile of cement next to them, with a strange expression on their faces, Li Shimin frowned and said, "Only relying on these ashes?"

They saw it when they came just now, those craftsmen were plastering the plaster on the wall, isn't this thing just mud?What can it do?

Su Cheng said with a smile: "This is called cement. It is mixed with sand and water, and it will become extremely hard after it dries. The city wall over there is almost dry. Your Majesty can try it!"

Seeing that Su Cheng still looked confident, Li Shimin was skeptical and led the crowd towards that side.

The wall is not very thick, everyone looked at it, and some people touched it with their hands, and it was really hard to the touch, even if they picked it with their fingers, they couldn't remove a little bit, it really didn't look like ordinary mud.

But it's hard to say whether it will work or not. After all, the enemy doesn't use his hands to pierce the battle. When fighting, the city wall must withstand the test of the bow and crossbow.

Yu Chigong scratched his head and said, "Why do I think this city wall can collapse with a single blow!"

Many generals nodded, they also felt this way, of course because the wall is not too thick, it looks similar to the courtyard wall at home.

As far as the courtyard wall of their home is concerned, they can definitely open a gap with a hammer!

Su Cheng encouraged with a smile on his face: "I have heard for a long time that the Duke of E is very brave, and I just want to open my eyes!"

Yuchi Gong laughed and said: "It's just a wall, a certain hammer will smash a big hole!"

Li Shimin said with a smile: "Then let Jingde try!"

"Okay!" Yuchi Gong responded, then picked up a hammer on the ground, and strode to the wall, got off his horse and stood still.

The crowd dispersed very consciously, staring at Yu Chigong with piercing eyes. Everyone still recognized Yu Chigong's brute force, and they also felt that the wall would probably collapse if Yuchigong hammered it down.

"I won't hold back!" Yu Chigong glanced at Su Cheng, then shouted loudly.

boom!

Yu Chigong slammed the hammer hard against the wall.

then.

The iron hammer was thrown away, and Yuchi let out a scream.

Su Cheng couldn't help laughing. It's no wonder he wasn't stunned when he hammered down hard.

However, no one cared about Yu Chigong who was jumping, and everyone's attention was focused on the wall.

The wall was not knocked down as expected. Although it was not completely intact, only some of the wall skin fell off.

Li Shimin and other ministers were all stunned, this result was too unexpected!

Li Shimin personally stepped forward to touch the place hit by the hammer, and a look of surprise finally appeared on his face.

Cheng Yaojin laughed and said: "I just said, this city wall must be very strong!"

Everyone couldn't help but glared at him and looked at him with disdain. You haven't farted since you came here, okay?

Li Shimin finally had a little excitement in his heart, and said loudly: "Get on the crossbow!"

The accompanying guards immediately set up their crossbows, and following Li Shimin's order, the buzzing crossbows resounded.

Finally, Gong Nusheng stopped. Although this section of the wall was completely changed, it didn't suffer much trauma.

After checking it out, everyone had surprise smiles on their faces.

"Haha..." Li Shimin laughed loudly.

"Okay, okay, Su Cheng, you're fine!" Li Shimin praised repeatedly excitedly.

Su Cheng smiled and said: "Your Majesty, the most important thing is that it is very quick and easy to repair with cement and bricks. For damage like this, just wipe it with cement, and it will be repaired after a few days when it dries!"

Li Shimin couldn't help but nodded when he heard this. When they came just now, they had seen the process of the craftsmen building the wall. It was indeed very simple.

Because the bricks have a fixed shape and do not have to be hammered like stones, it is very simple to build walls.

Of course, the most important thing is that you can use local materials!

There is no need to requisition civilian husbands, and there is no need to spend a lot of money on food, just let the garrisons in each border town repair it by themselves.

For a moment, Li Shimin felt very relieved, the problem was solved!Not only is it solved, but it can also save money and food, and there is no need to requisition civilian husbands!

Tang Jian, Shangshu of the Ministry of Industry, praised: "Bo Ankang is not only a great talent, but also so proficient in fortifications. It is really a blessing for me in the Tang Dynasty!"

Li Shimin asked with a smile: "Is it easy to fire red bricks and cement?"

Su Cheng said with a smile: "It's not difficult at all, these craftsmen will learn it as soon as they learn it!"

In fact, just after Li Shimin asked the question, he felt that he was unnecessary, because it had only been more than ten days since the rule of law, and the city wall had been built for such a long period, and Su Cheng was obviously sleeping just now.

Fang Xuanling, Li Jing and the others were still admiring around the city wall, and at the same time they kept discussing, with the intention of repairing all the city walls of all the border towns.

Su Cheng coughed and said seriously: "Your Majesty, in fact, the use of cement and bricks is not just to repair the city wall."

Li Shimin was a little surprised and said, "Oh? What else?"

Everyone's eyes were attracted by Su Cheng's words. The use of cement and bricks is not only to repair the city wall?what else?

Su Cheng smiled slightly: "For example, building a house!"

Build a house?Li Shimin suddenly turned his head to look at the other side of the wall. There are several houses standing there. Just now, everyone's attention was all on the wall, but they didn't pay much attention.

"Go, go and have a look!" Li Shimin strode there with great interest, because after confirming that the wall was strong, he felt relaxed.

After entering the house, everyone was a little shocked. Although this place is very simple, it cannot be compared with their magnificent mansion, let alone the magnificent palace, but this house looks very solid and spacious, unlike those The low dwellings are quite different.

Su Cheng said with a smile: "This is a house built with cement and red bricks, which is far simpler and stronger than wood and stones. More importantly, cement and red bricks are easier to obtain!"

Li Shimin was very satisfied and praised: "Not bad, very good, so that people all over the world can live in their homes!"

Changsun Wuji praised: "Thinking about it this way, cement and red bricks are indeed very useful. Let alone repairing the city walls, it is not difficult to build a city!"

Su Cheng chuckled and said, "Their uses are not limited to these!"

Li Shimin asked with a look of surprise: "Oh? What else can I do?"

Su Cheng smiled and said: "There are many uses, for example, building embankments, bridges, and paving roads..."

Every time Su Cheng said something, Li Shimin's face was a little more surprised, but he couldn't help being surprised at the end: "Pave the road?"

Not only Li Shimin, but Fang Xuanling and others also showed puzzled expressions on their faces.

Su Cheng nodded and said: "Yes, paving the road, Your Majesty has also seen that the cement is very strong after it dries, and it can be used to pave the road. The road will become very smooth and strong, and it will not be muddy even if it rains. This will greatly improve the carriage. The speed of travel, just imagine, if a road is paved with cement between Luoyang and Chang'an, how much can the time from Chang'an to Luoyang be shortened?"
