When he made up his mind, Jiang Yanhai directly began to do everything early rather than late. He directly joined the engineering forces to enter the interior of the Great Wall, found the most suitable node, directly figured out the whole structure by using the data analysis scanning program, and then began to install the directional blasting bomb.

At the same time, the engineering troops behind have also arrived, but what Jiang Yanhai didn't expect is that they didn't blow up the section of the front defense Taotie, but the section of the wall where Jiang Yanhai came in.

That section of the city wall is very narrow because it is not the main defensive force, and there are no various organs inside.

So the place where the blast opened was where the city gate was located.

All the ammunition was arranged in less than an hour. The reason why the city gate was blown open was that although tanks could come from the city gate, engineering vehicles and necessary heavy machinery could not enter.

So, just a little.

With a huge explosion, the great wall section where the city building is located collapsed directly. The calculated explosion equivalent directly collapsed the city building into a section of road about 15 meters wide.

When the city wall was blown down, the following part was directly entered by large excavators only used in the mine.

The huge bucket began to work directly. In less than an hour, the 15 meter wide collapsed section was directly cleaned out.

It's too easy to clear the road. The surplus stones are excavated by excavator, and the remaining parts are directly pushed aside by bulldozer. First clean the road, and then deal with it later.

When the roads here were cleaned up, the sound of "boom!" was a huge vibration. The front Great Wall defending Taotie collapsed again, and a section of the Great Wall with a width of about 30 meters.

Countless fragments flew everywhere, and this section of the great wall directly and completely collapsed.

But this time it was different from the treatment of the city tower, where all the gravel and the like were pushed away and the road was cleared.

But the front wall, because it didn't want to be blown up at the beginning, is high with the ground on both sides. The foundation itself is built on the ridge, so its foundation is higher than the ground on both sides.

When it is blasted, the crushed stones of directional blasting can make it collapse directly from both sides, and countless crushed stones directly form an inclined plane with the ground on both sides.

Of course, these slopes are made of different stones, large and small, so even tanks can't use this slope to drive up.

However, this thing is very simple. The engineering forces do not know how many new things have been updated, especially the materials produced by the combination of different materials in the two worlds, which has opened Jiang Yanhai's eyes.

First of all, the engineering force directly drives into the ground with thick steel columns on both sides of the inclined plane, and then inserts them vertically with steel plates. Both sides of the inclined plane are immediately completely blocked by steel plates. Then countless cement trucks and concrete pouring trucks behind drove over in an instant.

"What are you going to do?" Jiang Yanhai asked curiously, because he didn't know what the other party was going to do. He directly poured the gravel with cement, and then formed an equal slope? I'm afraid it won't be much stable?

"New type quick drying cement, chief, just look at it." the person in charge of the backward engineering unit raised his eyebrows proudly.

Jiang Yanhai shrugged his shoulders. He could only watch. He didn't know much about these. To tell the truth, he didn't know how many things scientists tossed out during this period of time. No wonder China has spared no effort and agreed directly after learning that there is a new world.

Lin dianshuai and others were watching. The power of these huge steel machines once again shocked everyone in the shadowless forbidden army. They said that those ordinary soldiers even thought Jiang Yanhai and they were gods. Otherwise, how did these huge machines come from.

"Special type I quick drying cement, mix No. 2 materials!" with the command of the logistics personnel, Jiang Yanhai saw that next to the front large water conservancy mixer, soldiers directly poured a bag of white powder into the mixer.

Then the mixer truck began to mix directly. About 5 minutes later, the mixer truck and the concrete pouring truck were connected together, and the quick drying cement was directly extracted from the mixer truck.

When the nozzle of the concrete truck began to pour cement into the slope formed by the gravel, Jiang Yanhai was stunned, because these quick drying cement are very thin, or it is more like a gray liquid. This thing... It is estimated that it is not much thicker than water, but much thinner than cement anyway.

When it is poured on these crushed stones, because it is a very thin fluid, it can flow directly into the cracks between the stones like water along those cracks. In this way, a can of filled cement tanker keeps driving in, and the released things drive away directly.

On the slope closest to the ground, these quick drying cement should have penetrated under the gravel and spread to the surface of the gravel. After all, they are not water. There is no problem to penetrate into the gap between the stones. It is estimated that it is a little choking to penetrate into the soil.

When the quick drying cement passes over the gravel surface, the concrete truck will not pour the place and let it flow down the slope.

But in the process of flowing down, Jiang Yanhai saw its speed slow down gradually.

15 minutes. It takes 15 minutes for the concrete to be mixed in the mixer truck. This time is slower than some quick drying cement. However, Jiang Yanhai is surprised that the liquid with such a high proportion of water solidifies directly after a special chemical reaction, just like freezing water into ice.

"This is our new type of quick drying cement. It can penetrate into many fine cracks. Some river sand that has not been screened can directly penetrate, and then solidify in 15 minutes, and its strength is very strong!"

"The strength is similar to that of some special cement. If it is matched with steel bars, its strength is not as strong as that of previous super reinforced concrete buildings, but it is only one level worse than that of ordinary civil buildings." the project leader gave Jiang Yanhai a general introduction.

The person in charge of the project did not directly irrigate the 30m wide slope section, so it was useless. First, a 6m wide slope road was irrigated, which was enough for use.

15 minutes is enough. Several concrete pouring trucks work together. In two hours, a 6m wide slope highway across the foundation of the Great Wall appeared here.
