"This is the newly appointed Director Liu, the son of Director Liu Suzhi, and the person in charge of the 619 project......" When Liu Yijiu was still shocked to see the guard at the gate, Xie Heping got out of the car and introduced to an old man who was about his age in a white-washed Mao suit.

When the old man heard this, he immediately frowned, and it seemed that he was a little shocked by Liu Yijiu's youth.

When Liu Yijiu saw this scene, he opened the car door and got out of the car, and smiled at the old man who had been looking at him, it was a greeting, he didn't know what this old man should be called.

"You shouldn't have brought him here now." The old man did not introduce himself, but said coldly to Xie Heping.

Xie Heping nodded and agreed with the old man's point of view, "The ability he showed is indeed very good, but it is really early to bring him here now, although he has learned a lot of physics knowledge from Mr. Qian Sanqiang, Qian Xuesen and Zhu Guangya......

The dialogue like playing a dumb riddle gave Liu Yijiu an urge to kill, but when he saw the heavy machine guns facing them, he had no choice but to smile bitterly.

Isn't this base part of the Ninth Academy? Doesn't it mean that this is a nuclear power plant, which supplies the energy of the entire Ninth Academy?

The garrison outside far exceeds that of the Ninth Academy, even if it is the research of a small reactor with a nuclear submarine in the underground part of the Ninth Academy's base.

"And you're bringing him with you? The base management committee wouldn't make such a mistake! Now it's not his right to know about these projects......"

"If you don't let him know, it will affect the progress of all projects in the entire base. We also have no way to do these things. There is no way to hide this consequence. It's not something any of us can afford, because his name is Liu Yijiu......" Xie Heping said with a bitter face.

Here are some of the items. It is very important for the entire Ninth Academy, and in the entire country, in addition to the people here, there will be no more than ten people who know about this project, and some of them have passed away.

The old man didn't speak, and after a lot of Liu Yijiu, he sighed.

"This is the person in charge of the nuclear power plant. Liu Suxue ......" Xie Heping said to Liu Yijiu, whose brows had been twisted into a Sichuan character.

"Old Liu, hello......" Liu Yijiu put away the thoughts in his heart, he felt that these secrets, sooner or later, would be solved, he really wanted to ask this old man what the relationship was with his father Liu Suzhi, according to the Chinese naming convention, if Liu Suxue has nothing to do with Liu Suzhi. Liu Yijiu felt that it was a little impossible.

It's just that Xie Heping didn't introduce any relationship between them, and the old man didn't show closeness to him.

"Alright, come in with me. Now that you've become the director of the base. They think you can be here, and that means you're up to the mark. Liu Suxue ignored Liu Yijiu's outstretched hand, but turned around and walked towards the cave.

The passage of this base is relatively wide. Compared to the passage on the side of the Ninth Courtyard, it is much better, and the more you go inside. It became more spacious, which made Liu Yijiu a little surprised. It's like a natural cave.

The more this is the case, the more doubts in his heart become, this is not a karst landform, and he has never heard of any big natural caves in Daba Mountain.

The site selection of the nuclear power plant requires that there must be no fault zone in the deep part of the site, and there is no active fault within several thousand meters of the nuclear power plant, the site is 100 kilometers in the sea area and 50 kilometers inland, and there has been no earthquake of magnitude 6 or higher in history, and there is no tectonic background of a magnitude 6 earthquake in the site area for 600 years.

The choice of this place also means that these areas must have been explored in detail in the first place. Even the Wenchuan earthquake decades later, it seems that it is very far away from this place. The mountains in these places are all covered with stable rock formations.

"This is a natural cave, the overall space is more than one million cubic meters, after artificial repair, a very good space ......," Liu Suxue introduced the situation inside the cave to Liu Yijiu.

From the door to the inside, I walked a distance of fifty or sixty meters, and I saw a huge space, which actually has a lot of heavy equipment!

Machine tools from various countries and cranes lined up, which made Liu Yijiu frown.

"This is the precision machining workshop of the Ninth Academy base, maybe you have seen it these days, there are some parts in the base that are shipped back from the outside......" Xie Heping introduced to Liu Yijiu.

Most of this equipment is idle. But there are still a lot of equipment running, and in front of the huge machine tools, human beings seem so small.

But if it weren't for the operation of these tiny workers, the equipment wouldn't have turned. The harsh sound unique to metal cutter cutting heavy parts is not very obvious, it stands to reason that in a closed space, this sound will become more harsh because of the echo, and it will echo in the entire cave, Liu Yijiu was a little surprised, why is the sound like this, especially at the entrance of the cave!

"How did the equipment get in from the outside? The road can't be passed, right? Liu Yijiu took a deep breath, this is a black technology base?

"Take it apart and bring it here to assemble. At the very beginning, this base was actually intended to be the base of the Ninth Academy, but the surrounding terrain was not good, and the area inside could not accommodate the entire system, so in the end, Director Liu decided to build a power station here, at first it was oil-fired power generation, and then it was a nuclear power plant......" Xie Heping's introduction made Liu Yijiu completely messy.

The amount of oil extraction in the republic has always been a hard hit.

After the founding of the People's Republic of China, it was called an oil-poor country for many years, and if it were not for the discovery of the Daqing oil field, the republic would basically not be able to meet its needs.

Now tell him that there is actually a power station that uses oil to generate points, and it is also used for the entire base of the Ninth Academy!

How much fuel do you have to consume this year?

It's just kidding yourself......

"Don't forget, we are here in the Ninth Courtyard, and the 619 project with two bombs and one star is equally important! So, it's normal to need to use oil to generate electricity in it. And the Aerospace 002 base next door, they use coal to generate electricity, after all, they have a railway that directly leads to the inside of the base......" Xie Heping saw Liu Yijiu frowning, and naturally knew what he wanted.

Liu Yijiu didn't speak, there is no clear division of the machining area here, and all kinds of equipment are placed in a messy manner, rather than placing these equipment together according to the type like the general large-scale machining unit.

Special machine production line!

This is a special aircraft production line from the USSR.

Liu Yijiu has never seen a complete large-scale production line, but he is really a little surprised to see it here.

A lot of large parts can't be shipped out the road outside.

"These are propellers?" Liu Yijiu couldn't help but be dumbfounded when he saw the blade-like parts on the huge gantry copy milling machine.

"Since you already know that there is a reactor for a nuclear submarine in the base, you should also understand that you need to have a supporting propulsion system......," Liu Suxue said lightly.

It seems that it is very normal to engage in these things in this mountain.

Liu Yijiu sweated one.

The military-industrial projects of the republic in this era cannot be inferred by common sense.

The nuclear submarine was an experiment in Dianchi Lake at the beginning!

Continuing to go a few hundred meters deeper, the space of the cave was clearly artificially divided. Because they are all reinforced concrete structures, a wall is actually up to three meters thick!

"It doesn't seem too loud?" Liu Yijiu asked suspiciously.

"You can see it when you look up......"

Liu Yijiu looked up, only to find that the top of the cave inside was actually rotating in a circle like a conch, and he immediately understood that the sound inside was transmitted from above.

At the entrance of the cave, because of the air pressure, the wind blows into the cave, and in front of this wall, it will rise, and the spiral structure allows these sounds to gradually transmit to the top, plus some powerful fans are blowing inside the cave, this is a simple wind tunnel!

"Artificially modified?"

Liu Yijiu does not believe that this is a natural formation.

"There is a part, from 58 years, this project did not end until 69 years......" Liu Suxue's voice is still very weak.

"This piece is the accommodation area, and further inside, it is the research area, and the nuclear power plant is still more than 700 meters away...... pointing to the rows of doors that are like prefabricated houses, or more like beehives, Xie Heping introduced to Liu Yijiu.

"People live here for a long time, and there is no sunshine, won't there be problems?"

"That's why District Nine exists. On the 9th side, it's the same situation as here, the workers and researchers, in it, work for a while, and then work in the 9th district for a while. Of course, there are also some dormitories on the top of the mountain, mainly for researchers......" Liu Suxue, the person in charge, did not introduce, but Xie Heping introduced these situations.

Sure enough, it has something to do with the Ninth District.

What's in there? would actually use such a method, don't think about it, this must be made by your cheap dad.

How insecure does he have to be to do something like this?

There's no need at all, isn't it?

Moreover, there is such a first huge cave in it, could it be that aliens made it? Thinking of this, Liu Yijiu couldn't help but shake his head, this is obviously a bit nonsense.

Even in his time, there was no obvious evidence that there were aliens in this world.

Even if there is a part of the research project on nuclear submarines, there is no need to be so rigorous, right?

If you just look at a certain part, no one will think that the project here is aimed at nuclear submarines, after all, the nuclear submarines studied in the mountains, in the entire history of the world, there is only one republic, and there is no other semicolon. (To be continued......)
