Considering that Ji Feng's three armies had to deal with the Mongolian tribes and protect the people, they were slightly insufficient. Therefore, in order to better target the Mongols and better protect the 200,000 construction men who entered the Mongolian steppe, Zhu Ciji once again transferred a regular army, the 17th Army and a garrison army, and 40,000 people entered the Mongolian steppe with 200,000 people.

100,000 troops, 200,000 people, with Ji Feng, commander of the First Army, as the main general, and Chang Shunhou, commander of the Seventh Army, as the deputy general.

"This is cement?" Ji Feng looked at the bags of cement packed in a large number of cloth bags that were transported, and said with some disbelief: "I don't know if the cement in this bag is really as powerful as described!" ”

According to the description of the leader who sent it, the slime made of this cement does not need an hour to condense, and it is extremely strong, stronger than the traditional glutinous rice syrup mixed clay.

"Don't you know when you're ready to use it?" Chang Shun said.

Ji Feng nodded, indeed, if you want to see it, you can see it when you use it, and you will know what the situation is at once.

The first city was built in the Ulanqab grassland, just north of Datong, which belonged to the Chahar grassland.

Chahar is known as the Golden Tribe, and the Chahar King is a direct descendant of Genghis Khan, known as the Golden Bloodline, and the grassland occupied by Chahar is no worse than the Horqin Grassland, and even slightly better than the Horqin Grassland.

When Zhu Ci threw hundreds of thousands of troops from the Northern Expedition into the Mongolian steppe, it was by defeating Horqin and Chahar successively that he finally shocked the other Mongolian tribes and forced the other Mongolian tribes to surrender to the Ming Dynasty.

Chahar as the original Mongolian second largest tribe, after the destruction of Horqin the current Mongolian first tribe, a total of 330,000 people, Ji Feng and other four Ming regular army and a garrison army and other 100,000 troops are stationed in Chahar, 200,000 people into the Mongolian grassland also came to Chahar, it can be said that Ji Feng and others in front of the Chahar Mongols in the Chahar grassland began to establish the first Mongolian city.

There is no doubt that once this city located in the Ulanqab area of the Chahar grassland is built, it will definitely radiate the entire Chahar grassland, and then the entire Chahar will be under the supervision of the city, and the Chahar people will only be able to submit to the Ming Dynasty forever, and there is no place to turn over.

Under the protection of an army of 100,000, 200,000 people began to quarry nearby stones, and then mixed cement with sediment and began to build the city.

The entire Mongolian steppe has to build 30 large cities and hundreds of small castles, of course, it is impossible to use all stones, although the stones are stronger, but the amount of work is also larger, and it is difficult to collect enough stones in the Mongolian steppe, so in order to be simple and fast.

When the city wall was built, only the outer part of the city wall was built with stones, and the inside of the city wall was poured directly into it with cement mixed with sediment.

When I was in Nanjing, the craftsmen of the Academy of Science and Technology experimented, although the center of the city wall was filled with cement and sand, but after condensation, its solidity was not much worse than the traditional city wall built with stones, at least it was extremely difficult to destroy it.

200,000 people surrounded a place more than 1,000 meters long and wide, and built the city wall together, and the speed was extremely fast.

In two hours, the city wall had been built a little, and the first place had been condensed, and Ji Feng and Chang Shun tried to test the hardness.

Ji Feng kicked hard at the top stone, but he didn't kick it.

"Hey, the speed of this condensation is still quite fast, and the degree of solidity is also quite strong, the Institute of Science and Technology has really made such a thing, at this speed, 200,000 people will work together to start construction, I am afraid that all four city walls can be built in a month." Ji Feng said with a smile.

Chang Shun next to him nodded, paused and said: "In fact, there is no need for 200,000 people to gather together to build a city, it is best to divide it into two or three parts and build two or three cities at the same time." ”

"Yes, it's a pity to guard against the Mongols jumping over the wall, at least after the first Mongol riot, suppress a few large tribes, and then disperse the people." Ji Feng said.

The Mongolian steppe is very large, and there are many large and small Mongolian tribes, and the Ming Dynasty wants to break the foundation of the Mongols, and it is inevitable that the Mongols will unite together and jump over the wall, and the Mongols who will riot in the first wave will also be the most.

Don't look at the scattered sand of the Mongolian tribes, the largest Horqin was destroyed again, and the second largest Chahar was also disabled, but the Mongolian departments united and it was not a problem to gather 200,000 cavalry.

The 200,000 Mongolian cavalry may not be looked upon by Ji Feng and others, but they have to divide their forces to protect 200,000 people, and while defeating 200,000 Mongolian iron cavalry, they must also protect 200,000 people, without a single casualty. If the people are scattered, the army will also be dispersed, and it will be extremely dangerous before the Mongol tribes are defeated.

"The Mongolian ministries are now afraid that they have only received the news that the Ming Dynasty has built a city in Ulanqab, they are likely to think that the Ming may only build a city to monitor the Mongolian steppe, and if it is only a city, it may not be within the scope of their patience, and when they are sure that the Ming will build thirty big cities and hundreds of small castles in the entire Mongolian steppe, they are afraid that they will jump over the wall in a hurry, and this time may take at least three or four months, do you think we should think of a way to take the initiative to tell the Mongols our strategy, Is it better to force them to jump off the wall as soon as possible? Ji Feng thought for a while and said.

Ji Feng didn't have the patience to wait for three or four months, and among the instructions given to him by the emperor was to arrest the Mongols in the Mongolian tribes who dared to participate in the riot to serve as coolies, and if the Mongols did not riot for a long time, how could he arrest them in a bright way? When will the construction of the Mongolian steppe be completed?

"What is Commander Ji's opinion?" Regarding Ji Feng's proposal, Chang Shunhou was a little moved, and asked with a smile.

Indeed, instead of waiting for the Mongols to revolt all the time and beware of the Mongol revolt, it is better to find a way to force them to revolt as soon as possible.

"Of course there is a way!" Ji Feng thought for a while and said: "It's also very simple, we directly convened the Mongolian ministries to discuss, clearly told them the strategy of the imperial court, and according to the approximate location of the city marked on the map, pretended to let the Mongolian departments cooperate in the selection of specific locations, and at the same time, we sent a large number of scouts to conduct a large-scale exploration according to the approximate location of the city marked on the map, so that the Mongols know that we are not joking, and we are already doing it." Coupled with the simultaneous construction of 200,000 migrant workers in Ulanqab City, and with the assistance of cement, it can be built in a month, such a speed, even our surprise, let alone the Mongols, when it falls, the Mongols are afraid that they are not surprised, but frightened, I don't believe they can bear it! ”

"It's called Mingqiu!" Ji Feng finally smiled extremely sinisterly and emphasized this plan again.

"Captain Ji's plan is really high, too high!" Chang Shunhou also smiled, and also laughed extremely sinisterly, it is true that such a plan, and the speed of the city-building shown by Ulanqab, the Mongols must be like ants on a hot pot, and they must not be able to hold back for a moment, afraid that they will immediately form an alliance to resist, and this is exactly what they are looking forward to.

Before it ended, Ji Feng and Chang Shunhou looked at each other and laughed here again and again, and finally evolved into a wild laugh.
