Great Tang Dynasty

Chapter 1463 Cement
When I returned to Yumen Pass, it was already the end of the year.

In a few days it will be New Years.

The taste of the New Year in Yumenguan is still very strong.

Every household also posted Spring Festival couplets and hung lanterns.

In this cold and windy place, after people saw these scenes, they couldn't help feeling warm.

How much, offset the nostalgia of some soldiers.

Far away from my hometown, I really miss it at this time.

Therefore, after returning to Yumen Pass, some soldiers couldn't help drinking more wine.

Regarding this situation, Qin Tian had no organization.

Although soldiers are soldiers, they also have their own emotions, which cannot be hindered.

After Qin Tian came back, he didn't stay idle, he found Yang Wudi.

"General Yang, although Yumen Pass is gradually becoming more and more prosperous, the city is a bit too dilapidated."

Qin Tian has seen the walls of those small countries in the Western Regions, they are simply vulnerable, and the city of Yumen Pass is similar to those of those small countries in the Western Regions. It is very difficult for such a city to have a certain degree of defense.

As long as the enemy also has trebuchets, it is not difficult to defeat this.

And something like a trebuchet is not difficult to do.

After Qin Tian said this, Yang Wudi smiled wryly, and said, "Little Grandpa, this kind of place is surrounded by deserts, it's not easy to get some stones to build a wall, if you really want to do it, it's not easy." It’s not impossible, some merchants do this business, and if you give them money, they can pull some stones from far away, but in that case, it will cost too much money, and we can’t support it.”

To build a city, you need stones, and there are many, many stones, but there are not many stones around here, and some are far away. If you pull them, it will indeed be a big expense.

Faced with this situation, Yang Wudi was very helpless.

Qin Tian also frowned slightly here, Yumen Pass can be said to be the throat of the Tang Dynasty, it is very important to the Tang Dynasty, but such a strategic place, the city is not very strong at all, in this case, it is really a very difficult situation. great potential threat.

After thinking about it for a while, Qin Tian felt that if there was cement, the matter would be easier to handle.

After cement is mixed with sand, it has a strong viscosity and is very strong. There is a lot of sand here. If there is cement, the city wall of Yumen Pass can be built very firmly. It is difficult to break through the attack.

After having this idea, Qin Tian heaved a sigh of relief, and said, "General Yang, it's time to repair the city of Yumen Pass. I will get some cement out, and when the time comes, fools will be mixed together to build the city wall."

"Cement, what is this?" Yang Wudi was a little surprised, but Qin Tian didn't mean to explain, just smiled: "You will know when you get it out, now, you can send people to tear down the original city wall."

"This……"

He still doesn't know what cement is, and the old city wall is about to be demolished, which makes people a little uncertain.

But at this time, Cheng Chumo and the others couldn't stand it any longer, and began to mutter.

"Brother Qin wants you to dismantle it, so you can dismantle it. Can the things that Brother Qin can produce be worse?"

"That's right, you'll be shocked when the time comes for safekeeping, so just do what Brother Qin said."

Yang Wudi had just made contact with Qin Tian, ​​and his confidence in Qin Tian was not as good as that of Cheng Chumo and Yuchi Baolin, so Yang Wudi hesitated, and Cheng Chumo and the others started talking.

Seeing Cheng Chumo and the others like this, Yang Wudi didn't say anything else, nodded and agreed, and then sent people to demolish the city wall.

Here, Qin Tian began to research and develop cement.

It wasn't very easy to get this thing out, but Qin Tian couldn't help it with his golden fingers. After two days, he got out the cement.

After seeing the cement, Qin Tian was so excited that he quickly called Luo Huang over.

"Find someone, and immediately give me a large-scale production of cement, but the secret recipe of this thing must not be known to anyone."

Cement is very helpful for building houses, city walls and so on, and in terms of city walls, it can build the strongest things that appear today, so the importance of this thing is self-evident.

If the secret recipe of gunpowder is the most powerful for attack, then cement is crucial for defense.

Luo Huang was naturally aware of this, and quickly nodded in response.

Luo Huang asked someone to produce cement on a large scale. After a batch was produced, Qin Tian brought Yang Wudi and the others to the gate of the city.

Here, the former old city gates and walls have been demolished, and now there is an open space, surrounded by some old stones, and some things picked up from some abandoned houses.

"Okay, now let's experiment with cement."

Soon, Qin Tian mixed cement and sand together, and then began to build the wall. After mixing sand and cement to build the wall, the speed is very fast, and it can save a lot of stones. It didn't take long for Qin Tian and the others to build a wall.

The wall doesn't look very thick, but it is very strong.

"General Yang, come and take a look."

Yang Wudi did not expect that the cement Qin Tian made could be mixed with sand, and could bind those stones very firmly.

He took a look at those city walls, and then he was sure that if all the city walls were built, the defense power would be at least ten times higher than before.

"My lord, this cement is really good. After mixing it with sand, it saves a lot of stones. It is even possible to mix the sand with cement without using stones at all."

There is no need for such a large stone, and after mixing some other things, it is also very stiff and firm.

"With these things, Yumen Pass can be said to be impenetrable in the future."

Yang Wudi was very excited, and Cheng Chumo smiled: "General Yang, what's the matter, I'm not wrong, just trust us Brother Qin, after this Yumen pass, let's see who can break through."

"That's right, what Young Master Cheng said is reasonable." Yang Wudi smiled.

Qin Tian didn't say anything here, he just ordered people to quickly build the city wall. If it can be built higher, it will be higher, and if it can be thicker, it will be thicker. Anyway, the stronger the city wall, the safer they will be.

With the coming of the new year, Yumen Pass is very lively, but some other people are speeding up the construction of the city wall. These people are not stopping day and night. According to this speed, the construction can be completed after the Shangyuan Festival arrives.

At that time, Yumen Pass could be said to be truly impenetrable.

During this period of time, Qin Tian and the others were not idle. Anyway, they would help if they could, and build the city as soon as possible.

And just before the new year, before the Lantern Festival, a news came suddenly.
