After carefully checking the identities of Lu Qiujian and others again, the soldiers guarding the entrance of the cave let them in. After entering the entrance of the cave, bright lights illuminated the interior of the cave as if it were daytime.

"Perhaps you have heard of the 816 underground base that was declassified a few years ago! It is known as the world's first artificial cave." Li Jiajing continued to play the role of commentator, "But in fact, the cave in Yuzhou is far from worthy.

With this title, not only is it not the largest artificial cave in the world, but there are also several larger artificial caves in our country, and the one we are currently using is one of them."

"The entire cave has eleven floors, a height of 102.3 meters, and a total length of 35.4 kilometers. During the construction of the cave, 1.84 million cubic meters of stone were excavated. In this renovation, more than 200,000 cubic meters were excavated." Enter.

After that, it felt like being in a science fiction world. Lu Qiujian, who had experienced underground facilities, and Li Yan, who was experienced, were better. Ma Yang, who used to be mainly engaged in theoretical research, looked at the spectacular scene around him and opened his mouth in surprise.

.

"This cave has a total of eleven entrances. The one we just entered is the main entrance. The others include personnel entrances and exits, car entrances and exits, drainage outlets, air exhaust outlets, etc. It has independent power supply, water supply, ventilation system and a large number of

With material reserves, even in a fully enclosed situation, the staff in the cave can continue to survive for another year!"

Li Jiajin walked to the elevator, checked his fingerprints and pupils and irises, and a password disk popped up. He quickly entered the password, and finally took out a key. After a series of complicated procedures, the elevator door slowly opened, "

I will take you down to see the core area of ​​the cave, and everything has been transformed according to the drawings you gave me!"

Lu Qiujian used his heartbeat frequency to silently calculate the speed of descent. The elevator descended sixty-three meters and reached the core area of ​​the base.

After stepping out of the elevator, a huge and empty cave appeared in front of everyone. Although there were only basic facilities such as electric lights and elevators inside, Lu Qiujian had already imagined what it would look like after the equipment was installed based on the topography of the site.

The center of the front should be the location of the fusion reactor he had reserved. Above is the laser ignition device, below is the plasma confinement device, and there are dense conductor coils around it. Seeing that the plan he has been preparing for many years is about to be officially implemented, Lu Qiujian was excited for a moment.

The ground held its breath.

"This is the emergency evacuation passage. If there is an accident in the experiment, you can evacuate out in the shortest time through this!" Li Jiajin seemed not to notice anything strange about Lu Qiujian and continued to introduce.

Ma Yang curled his lips and said nothing. Li Jiajin may not know what is being studied here; but he knows that if the most worrying accident really happens here, I am afraid that this emergency evacuation channel can only be used as a decoration! But even though

In this way, there was still no worry on his face, but excitement flickered in his eyes. It seemed to him that if he could verify the theory he helped Lu Qiujian refine some time ago, then what's the point of taking such a small risk?

"This should be a super computer room!" Li Yan pointed to the cave on the other side and said. According to Lu Qiujian's request, the country will allocate a Dawn-class computer with a running speed of one trillion times to be placed here. Later, it will also

Add the Tianhe series that is currently being pressed, which runs faster and has more powerful functions.

After staying in this largest cave for more than an hour, the group took the elevator to another cave; that is the area where controlled nuclear fusion supporting technology research is conducted.

It is not enough to have a controllable nuclear fusion reactor alone. A more powerful power transmission system, high-capacity and high-efficiency new batteries and even reactor miniaturization research and other related technologies are needed to develop together, so that the true efficiency of controllable nuclear fusion can benefit everyone in life.

Every corner.

Some of these technologies can be developed by other units. For example, power transmission systems. China is at the world's advanced level in some areas of power technology. They have accumulated enough experience in power supply and transmission. This work is done by them in this country.

It is much more convenient to complete the unit than here; of course, the parts closely related to the controllable nuclear fusion power system still need to be studied here by full-time personnel.

The entire cave forms a black science and technology research center centered on controllable nuclear fusion. It is divided into several groups and conducts simultaneous research under the unified coordination of Lu Qiujian. When the controllable nuclear fusion reactor can operate stably, other fields should also

Once the results are achieved, China will be able to upgrade its industry with controllable nuclear fusion as its core.

Similarly, the security level of each area in the cave is different. Each staff member can only work and act in the corresponding area according to his own authority. If there is a problem of entering an unauthorized area by mistake, he will be subject to strict scrutiny; this is to a certain extent

This can ensure that the secrets of the base will not be leaked to the outside world.

"I originally thought that this base would withdraw from the stage of history like the one in Yuzhou. I didn't expect that it would be revitalized this time! I believe that many years from now this base will become another shining holy place in the history of China!

"After the visit, Major General Li Jiajin said with emotion.

I guess it will become the base of villains in Hollywood works, right? Lu Qiujian secretly thought, how will Hollywood describe itself? A black hand hiding behind the scenes trying to destroy mankind? Or a hero who leads mankind into the universe? I'm afraid the former is more likely.

Some, right?

Such a large-scale project cannot be completed in one day. Today, Lu Qiujian just took a quick tour to understand the progress. As for other detailed issues, Li Yan will stay here to continue communicating with Major General Li Jiajin; according to the visit

The result of the discussion between the three after the end was that Li Yan still needs to stay in the base for about a month.

After staying at the base to rest for one night, Lu Qiujian left Li Yan behind the next day and took Ma Yang to leave the mysterious base in the mountains and head back to Chang'an city. He still had other work to complete.

Whether it is a plasma confinement device with controllable nuclear fusion or a conductor, it is inseparable from certain rare metal elements. After they officially enter the base, as the experiment proceeds, the demand for this rare metal element will increase.

According to the current total production volume in the international market, it cannot meet the needs of the project at all; then the current task is to select several manufacturers and provide them with financial and technical support to allow them to expand production.

Therefore, the first cooperative unit Lu Qiujian visited was Changan Nonferrous Metals Company. (To be continued.)
