In the factory of Zhang's Heavy Industry, a huge thing is being assembled.
After Zhang Fan exchanged the Earth-Drilling Dragon, he opened the thing directly. Zhang Fan handed over some parts to dozens of secret companies for production.
Zhang Fan has some secret companies in his hands. These companies are only responsible for research and development, but do not produce marketed products or sell anything.
These companies are independent of each other, and no one knows who. And they are all under the highest level of secrecy, just to keep it secret.
Dozens of core components of the Earth-Drilling Dragon were handed over to dozens of companies for production. After production, they were assembled by Zhang Heavy Industries.
The Earth-Drilling Dragon is a super high-tech product. Its technological level is fifty years ahead of this era. The dozen or so alloys used in it are all unavailable in this era.
The Earth-Drilling Dragon is a comprehensive product, and it cannot work without any one thing. These alloys are even less clear and have none at all.
Even if a complete Earth-Drilling Dragon is stolen, there is basically no hope of reverse research and development unless there is a major technological breakthrough.
To give a simple example, it's like the most advanced stealth fighter in the United States crashed through construction in China when the People's Republic of China was just founded.
Even if you have a complete fighter jet, can you develop it? It doesn't take decades, and it doesn't require a terrible investment. Don't even think about reverse research and development. It's not a technological level at all.
So there is no need to worry about the earth-burrowing dragon Zhang Fan.
In the workshop, Zhang Fan swallowed his saliva as he looked at this super big guy. Only after the assembly was completed did he realize how big this thing was.
A giant steel beast with a diameter of 35 meters and a length of 120 meters. It looks like a giant steel snake. The entire Earth-Drilling Dragon has a total of twelve sections, each section is ten meters long.
They are closely connected to each other, but the outer shell is made of special metal. This special metal has very good toughness, just like rubber.
But when a constant voltage current is input, it will become super hard. The hardness is twice as hard as diamond.
"Let's go, try..."
Zhang Fan directly issued the order, and the specially manufactured transport vehicle was started directly. The Earth-Drilling Dragon was transported away section by section.
The huge carrier vehicle is much more exaggerated than the missile vehicle. The width of the carriage alone reaches 12 meters and the length reaches 37 meters.
Just enough to lay down one section of the body of the Earth-Drilling Dragon on its side.
Although the body of the Earth-Drilling Dragon is large, its weight is not exaggerated. Because a large number of lightweight materials are used inside, one section of the body only has a weight of fifty tons.
This kind of weight is nothing at all for such a heavy-duty vehicle.
But the behemoth also attracted countless people to watch. The road was directly blocked by private security, and a huge convoy was on the road.
Fortunately, the private road was wide enough, and twelve large vehicles drove directly along the road towards the desert.
We finally arrived at the testing site, which had already been prepared. A temporary huge tent was set up here.
The huge tent covered the entire surrounding area. After the convoy entered, the place was sealed and no one could enter.
The private territory operation was soon known to various countries, and they directly mobilized military satellites to conduct reconnaissance and photography of the area.
But no one knew what was going on. The huge tent covered everything. No one knew what was going on inside.
The test area is in the desert, and all the personnel are the core personnel of the private sector, so no information can be found at all.
The more mysterious it is, the more curious they are. Countries directly give orders to agents to find out what Zhang Fan is doing.
In the tent, the Earth-Drilling Dragon was hoisted down, and then the docking was completed. When the docking was completed, Zhang Fan directly entered the main control room.
This earth-boring dragon is remotely controlled. Through the 5g network, real-time remote control can be carried out.
Zhang Fan started the Earth-Drilling Dragon and entered specific data.
When the working switch was turned on, the huge burrowing dragon started to move. Like a huge earthworm, its neck was slightly raised, and its originally square head became tilted.
Then a scene that stunned everyone appeared. The blade in front of the huge Earth-Drilling Dragon rotated, and the Earth-Drilling Dragon burrowed directly into the earth like an eel.
At the tail of the earth-boring dragon, soil is quickly sprayed out from the reserved pipe. The excess soil is sprayed out directly through a specially made hose, just like the earth dragon defecates.
The Earth-Drilling Dragon burrowed into the ground at an angle, and its speed was very fast. It only took ten minutes for its body of several hundred meters to penetrate completely into the ground.
Everyone swallowed their saliva, and underground, the earth-burrowing dragon began to level off thirty meters underground.
Even though the private land is full of desert, the thickness of the desert is actually not very high. Even the highest place is only about ten meters at most.
Under the desert, there is still solid soil. So thirty meters underground, the soil layer is very stable.
The Earth-Drilling Dragon started working. This time, the Earth-Drilling Dragon used a drill bit with a diameter of forty meters. The Earth-Drilling Dragon can drill tunnels of different diameters using drill bits of different diameters.
The most bizarre thing is that the huge body of the Earth-Drilling Dragon can shrink inside and outside within a range of five meters. Now the diameter of the Earth-Drilling Dragon's body is 35 meters, so the drilling range of this Earth-Drilling Dragon is thirty to forty meters.
If you drill other diameters, you need to make another one with a smaller diameter. However, the technologies are all the same. In the complete information, Zhang Fan has an earth drilling dragon with a diameter of 100 meters, but that thing is more expensive to build and can be used in ordinary places.
Not used.
The Earth-Drilling Dragon was traveling at a speed of one kilometer per hour. This was because Zhang Fan had not reached the maximum speed. If the maximum speed was turned on, based on private geology, it could reach a maximum of five kilometers per hour.
This speed is too exaggerated. You must know that this is not driving, this is digging a tunnel underground, and it is a tunnel with a diameter of forty meters.
At the entrance of the cave, a group of experts were busy nervously looking at the huge entrance. They were conducting detailed measurements of the tunnel.
The measurement data came out soon, and this data made countless people take a breath of cold air.
The diameter of the earth-boring dragon's excavation is forty meters, but five meters of concrete are directly laid down during the process.
This kind of coagulant is more advanced. After this coagulant is mixed with soil, it will completely solidify in just a few seconds. The quality of the coagulant after solidification is twice as high as the quality of the coagulant in Zhang Fan's hands now.
In other words, the level of defense against condensate five meters behind is comparable to the level of defense against ten meters thick concrete in private areas today.
If it were replaced by the thickness of reinforced concrete, even the highest grade special concrete would be thirty meters thick.
This is not a tunnel at all. What Damn built is simply a military base.
Thirty meters of special concrete cannot be drilled even by the most advanced King of Bombs in the United States. This thickness is really overkill for tunnels. Seeing this specific data, Zhang Fan laughed.
