There are a lot of vehicles queuing up to enter the 51st district, about 100 of them, and there are all kinds of models, there are more than 20 large trucks, buses occupy the majority, and some cars.

There were quite a few people going in this time, about 600 people, but the treatment of these people was very different, some were locked up in box trucks, while others were seated in buses with their heads covered.

Seeing this, Chen Chen's brows furrowed, and he had a bad premonition...

Let's hope it's not what he thinks...

When a car enters the entrance to Area 51, it feels a bit like a normal car passing through a tunnel, except that the tunnel is diagonally downward.

The tunnel is made of reinforced concrete, with reflective arrows on both sides, and there is something like an airplane engine above the tunnel, which is supposed to divert air from the outside to the outside.

However, the huge base will definitely not only have such a simple exhaust outlet, this equipment only ensures that the air in the tunnel is unimpeded.

Area 51 should also have a special ventilation port, but he didn't notice it when he was outside.

But after walking for a while, he knew why he hadn't found out.

There are sometimes turns in the tunnel, but the whole tunnel is slowly sloping downward.

Even Chen Chen didn't expect that the real District 51 would be built here!

In the base above, there is a mountain range that is neither tall nor low in the back, and the base is built against the back.

But who would have thought that District 51 would be built at the bottom of the mountain? Doesn't that make construction more difficult!

It is said that Huaguo is good at infrastructure construction, but few people know that Mi Guo has passed the infrastructure boom as early as a few decades ago.

People used to be infrastructure madness, but later they didn't need it much in China, so they abandoned their martial arts.

There are many things to learn from abroad, and Chen Chen carefully analyzes the architecture here while observing the terrain.

It is normal to make a space in the mountains to come out, and Hua Guo himself has done no less.

It is rare to build underground fortifications at the bottom of the mountain.

It was difficult for his divine sense to extend too far in the rocks, but by careful observation, he slowly understood the doorway.

This mountain looks ordinary, but it is actually a pure rock mountain.

The base of the mountain, in particular, is made up of large rocks.

If this kind of mountain was in China, it would have been bought for stone mining a long time ago.

The United States built the base here, and because the rock apportioned the stressed area, the weight of the upper layer was not as heavy as imagined.

And I don't know how the country explored, some rocks with load-bearing effects were not moved, they strengthened them, and then hollowed out other unstable places to carve out a huge space.

The car drove slowly for about ten minutes, and Chen Chen could be sure that the air base on his head had passed.

Ten minutes later, a fork in the road suddenly appeared in front of him, and his divine sense quickly extended along the two forks.

The fork in the road is oval in shape, and from time to time there are tunnels leading to different areas.

His consciousness was unhindered in the tunnel, it could stretch far away, and he even saw the tunnel going down again, which was intertwined until it reached more than eighty meters underground, where a door was blocked.

There should be a higher level of secrecy, and according to his speculation, there will be tunnels downward!

Chen Chen's car went to a place forty meters deep underground, and after arriving at an underground parking area, next to it was one of the gates that entered Area 51.

The gate is an ID tag, and there are cameras on it, and there should also be facial recognition.

It's a bit like entering a train station, with bright lights inside, clean and tidy decoration, and two worlds with the outside world.

It's as if hell is on the outside and heaven on the inside.

Chen Chen followed the people in the car into it incognito, the temperature inside was cooler than the outside, and the air was still very fresh, what made Chen Chen strange was that the aura inside was a little richer!

There's definitely a jade mine underground! Otherwise, how could the aura be so strong.

He wants to fix it here

It's been refining for a while...

But as much as he wanted to go down there to find out, he knew what he was doing.

He's going to go up to the top and look down layer by layer.

His layer is the ninth layer, and his divine consciousness has unfolded, and he hasn't even seen the entire area of this layer!

What he could see was about the size of ten football fields, and the Fifty-One Sector didn't seem to be divided into test areas by the number of floors.

Because there is another half of this floor, the hatch is closed over there, and the other side is similar to this side, except that it is another experimental area.

The half of his area is the semiconductor component area, where the lab occupies most of the area and there are very few offices, which is typical of the practical style.

There were more than 1,100 people on his side, and there were a few Chinese faces mixed in.

This is all a normal phenomenon, and there are more cutting-edge Chinese talents working for other countries than expected.

Chen Chen has been watching all the way, and the utility of his divine sense has been used to the extreme, and he can probably see many semiconductor components, many of which are fields that China has not yet touched, and most of them are for military use.

He found an elevator and went straight into it with a retreat.

Well, this elevator can go up to the second floor and down to the fourteenth floor!

According to the level of confidentiality, the number of layers that can be easily achieved is generally not too high.

But don't underestimate this place, the level of defense outside is already high enough, and agents from other countries don't want to sneak in here.

After coming to the second layer, Chen Chen took a look, did Ma De just finish analyzing this and slapped him in the face?

The upper floor here is very large, more than twenty meters high, here... This is especially the place to study aircraft engines...

Such an important technology is placed on the second layer?

But then he understood that the second floor here seemed to be in the belly of the mountain, and the upper floor had a lot of space, which was just right for studying these large things.

Complex aircraft engines, Chen Chen couldn't understand at all, the crystallization of wisdom studied by human beings was different from cultivation, and the formation of cultivation was actually simpler than that of a complex machine like a mortal.

Of course, this is on the surface, the cultivation formation involves more things, the theory is not the same at all, a simple line, an angle does not know how long it will take.

And you can't use specific calculations to calculate, because if you want to solve a simple thing in detail, you will find that the more you explain, the more complicated it becomes!

In the end, it is so complicated that it seems to be endless.

The study of science is actually much simpler, at least there are various theories to base it on, and if you don't have it, you can create your own formulas.

How many years has Xiuzhen been developing? Before human civilization, there were many generations of true civilizations.

What generation doesn't have amazing characters? It's just that there are so many talents, and they haven't come up with a well-founded theoretical formula...

Formations are derivative, not calculated.

This is the experience of countless generations of ancestors, and it can't be solved with specific formulas, so it's better to use the theory of cultivating truth, the five elements of yin and yang, mutual growth and mutual restraint, and the laws of magic to derive it.
