Chapter 129: Outside Changchun Fort

"The commander of the Changchun Wei will make it safe, meet His Royal Highness King Yan, and meet the governor." Ping An took the generals of Changchun Fort to greet him on the dock.

The status of Changchun Fort has long been upgraded, and Ping An naturally became the commander. The establishment has been expanded. Now there is also a full guard under his command, with 5,600 people. Of course, there is also a guard in Ping'an, with hundreds of elite cavalry, which can be regarded as specially strengthened by Feng Sheng.

It is relatively safe and belongs to Liaodong in terms of subordination, but it is in Beiping in terms of roots. He Xi didn't interfere much.

King Yan said: "Flat." ”

King Yan carefully observed Changchun Fort, and also observed peace. Because in the eyes of King Yan, this is where he will be for a long time in the future.

According to the resolution of the Peiping Conference. Based on Changchun Wei, plus the three guards of Yanwang, there is also a guard transferred from Beiping. Established Changchun Division. King Yan's mission is to establish the future Changchun Metropolitan Division.

It's just that King Yan looks at Changchun Fort, which is different from other places in Guannei.

King Yan said: "I haven't seen you for a few years, General Ping is fast enough, and Changchun Fort has built another city?" ”

The fort of Changchun became a twin-city structure at the moment.

The original Changchun Fort has been built on the rectangular city of Changchun Fort. It looks like the area is larger than Changchun Fort, especially with a water gate, which can be directly entered by ships.

Ping An said: "This is also a last resort, in recent years, there have been many merchants on the grassland. Although by order of the imperial court, it was forbidden to buy and sell iron, iron tools, grain and other military materials. But other supplies are still available. And Liaodong set up a checkpoint here, the town guarded and paid taxes, and more and more people gathered, especially in autumn, many small tribes sold horses here. At its peak, more than 10,000 people gathered. I'm afraid something might happen. And he built it. ”

After safe guidance. He Xi saw the special features of this city.

This city seems to be larger than Changchun Fort, but in fact, it is more like an enlarged urn city. In the city, where there is no city wall, it shares a city wall with Changchun Fort. The walls of this city can only be climbed from Changchun Fort.

In addition, the shared city wall is one zhang higher than the other three city walls, and from the other three city walls, the Changchun Fort city wall needs to be attacked. Not to mention, close to the city walls, is the street, and there is no need for any buildings to get close.

It makes He Xi feel like a prison.

This is also the solution that Ping An has been thinking about for a long time to come up with. 、

There will definitely be a market outside Changchun Fort, or a market. This is not something that peace can deny. But the problem is that there is a lot of risk in building a separate bazaar.

Ping'an read the book of soldiers, and naturally knew the battle of Xiangyang between the Southern Song Dynasty and Yuan Youming. Although Lü Wende surrendered to the Yuan Dynasty. But his brother Lu Wenhuan is a very good guard. In the end, he died in the siege and did not waver. But Lu Wenhuan is obsessed with one thing.

That is the north of Xiangyang City.

Just like today. Although the Southern Song Dynasty and the Yuan Dynasty were hostile, there was still trade between them. Since there is trade. The merchant needs a place to trade.

Lu Wenhuan actually thought about it carefully, he was not negligent, it was best to demarcate a piece, not far from the city wall. However, the construction of the city walls was not allowed, and it was well observed at first. But for a long time. The merchants of the Yuan Dynasty said that they always ran away with their livestock. I hope to go around in a circle.

Lu Wenhuan didn't think anything, just a livestock pen. However, it was still ordered that only low walls were allowed, and high walls were not allowed.

But after a short period of peace, the Yuan army suddenly approached the city, and Lu Wenhuan had a counterattack when the Yuan army was not firmly established, and the enemy was caught off guard. But he never expected it. Almost overnight. What was originally a bazaar with low walls and cattle pens has become a fortified city. Now it is very close to the city, and almost out of the city is engaged in the attack on Xiangyang.

Lu Wenhuan's counterattack plan was stillborn.

The whole situation is in a state of passivity.

Lu Wenhuan was dying, and he was haunted by his mistakes.

Past experience, if not forgotten, is a guide for the future.. The Battle of Xiangyang has only passed for more than 100 years. How could a general like Ping'an, who has read a lot of military books, not know. He was afraid that the Yuan army would repeat his old tricks. After thinking about it, I finally came up with this solution. It is better to be overprepared than to repeat the mistakes of the past.

After hearing Ping'an's words, King Yan also nodded and said, "Not bad." In such a short period of time, such a majestic city was built, and it seems that the outside is covered with stones, which is indeed good. ”

He Xi smiled when he heard this: "His Royal Highness King Yan, you don't know. This is the role of cement. ”

Yan Wang said: "Cement." ”

He Xi directly took King Yan over and said, "Come on, take a closer look." These gaps are filled with cement. ”

Naturally, the city built by Ping An was not completely made of cement. Because the output of Daming cement is still quite insufficient. The method of building a city safely is similar to the method of building dikes in the seventies and eighties. The foundation is laid with rammed earth and then pieced together with large stones.

The gap in the middle is filled with cement. Even in the middle of the city walls. There is also cement mortar filling.

This city wall is formed in such a situation, where the stones are spliced, there are winding and net-like lines. It even looks like it has a unique aesthetic.

Of course, I don't know if Ping An is a concern about new technologies or a limitation of cement. It was built relatively low and thick, as if the wall was afraid of collapse. Don't dare to go to Gaoli to repair.

It is precisely because of the use of new technologies. Only then did this city rise in just one year. Of course, if you use sufficient manpower. It is not a problem to build a city within a year. After all, the construction time of Changchun Fort was also very short.

The problem is that Changchun Fort does not have enough manpower.

Not to mention how big Changchun Fort was at the beginning. When Changchun Fort was built, tens of thousands of manpower were used. That's why we have this speed. Now this city is larger than Changchun Fort. And Changchun Fort, and even Changchun Wei, there are only more than 10,000 people. that is, the soldiers and their families. It's also because it's too dangerous here. Many of the soldiers were not of age. Or the family didn't bring it with them.

This is also human nature.

Even if everyone were in battle, it would not be possible to accomplish such a task.

And with cement, it's different for a long time. Don't forget that when He Xi opened the canal, he blew up a lot of rocks with gunpowder, and these stones were useless wherever they were placed. There is also a waterway connection between the two places. It is extremely convenient to transport, although the foundation is rammed, and it is also very difficult to move stones. However, it is much easier than rammed earth for the entire wall.

Ping An also said: "Lord He is right. If there was no cement, it would not be unusual for the city to be built for several years. Cement is really a militaristic weapon. ”

After Yan Wang understood the use of cement, he didn't say a word, and said to He Xi: "How much cement is there?" I want them all. Ship them all over to me. When I was in Shenyang, you should have asked me to go see the cement factory. ”

He Xi said: "Didn't you remember this? And this cement output can never be given to you, and it is used in many places. ”

King Yan naturally refused. Bargain with He Xi under the city gate. He Xi said: "With so many people, you also have the appearance of a prince." Don't act like a scoundrel who wants to pay for it. ”

"What's wrong with the scoundrel?" King Yan didn't care at all, and said, "Don't care what I look like, it's true that I can ask for something." You don't give it. ”

He Xi said: "Okay. One-third, no matter how much you can produce, gives you one-third. Couldn't be more. ”

King Yan said, "It's okay. Let's do it first. ”

King Yan knew that he had a lot of work to do on this piece of land, and he originally wanted to build it for several years. But with such a sharp weapon as cement, Yan Wang felt that it seemed that within a year or two, he would have a way to do other things.

The more cement is produced, the better.

King Yan secretly said in his heart: "It seems that there is no more from He Xi." However, there are other ways. For example, go to the prince's eldest brother. Let the eldest brother of the prince come forward. ”

King Yan's thoughts, He Xi naturally didn't know. At this moment, they ended other topics, and under the greeting of everyone, they entered Changchun Castle. The soldiers and merchants all came to greet the city, and the situation was very grand. Of course, there are also alternative eyes.
