After carefully checking the identities of Lu Qiujian and the others again, the soldiers guarding the entrance of the cave let them and their group inside, and when they entered the cave, the bright lights illuminated the inside of the cave as if it were day.

"You may have heard of the 816 underground base that was declassified a few years ago! Li Jiajin continued to play the role of a commentator, "But in fact, the cave in Yuzhou is far from worthy of this title, not only is it not the largest artificial cave in the world, but in our country, there are several artificial caves larger than it, and we are currently using one of them." ”

"The whole cave has 11 floors, 102.3 meters high, a total length of 35.4 kilometers, the amount of stone excavated during the construction of the cave is 1.84 million cubic meters, and more than 200,000 cubic meters have been excavated in this transformation. After entering, it makes people feel as if they are in a science fiction world, Lu Qiujian, who has seen CERN's underground facilities, and Li Yan, who is experienced, are better, and Ma Yang, who used to be mainly engaged in theoretical research, looked at the spectacular scene around him and couldn't close his mouth in surprise.

"There are a total of eleven entrances in this cave, we just entered the main entrance, the others have personnel entrances and exits, car entrances and exits, drainage outlets, exhaust outlets, etc., which have independent power supply, water supply, ventilation systems and a large number of material reserves, even in a fully enclosed situation, the staff in the cave can continue to survive for a year!" Li Jiajin walked to the elevator and checked his fingerprints. After the pupil iris, a password disk popped up, he quickly entered the password, and finally took out a key, so that a series of complicated procedures were over, and the elevator door slowly opened, "I'll take you down to see the core area of the cave, where are all transformed according to the drawings you gave!"

Lu Qiujian used his heartbeat rate to silently calculate the speed of the descent, and the elevator descended sixty-three meters before reaching the core area of the base.

Get out of the elevator. A huge and empty cave was presented in front of everyone, although there were only electric lights, elevators and other infrastructure inside, but Lu Qiujian had already made up the picture after the equipment was installed according to the topography of the site.

In the middle of the front should be the location of the fusion reactor he has reserved, with a laser ignition device above and a plasma restraint device below. Seeing that the superconductor coil that had been around him for many years was about to enter the official implementation link, Lu Qiujian held his breath with excitement for a while.

"This is an emergency evacuation channel, if there is an accident in the test, then you can evacuate in the shortest possible time through here!" Li Jiajin didn't seem to notice Lu Qiujian's abnormality, and continued to introduce.

Ma Yang pursed his lips and didn't say anything, Li Jiajin may not know what is being studied here, but he knows that if there is really the most worrying accident here, I am afraid that this emergency evacuation passage can only be used for decoration! But despite this, there is still no worry on his face, and his eyes are flickering with excitement. It seems that in his opinion, if he can verify the theory that he helped Lu Qiujian refine some time ago, then what is the point of taking such a little risk?

"This should be a supercomputer room!" Li Yan pointed to the cave on the other side and said, according to Lu Qiujian's request, the state will allocate a Dawning supercomputer with a speed of up to one trillion times to be placed here, and the Tianhe series that is running faster and more powerful will be added in the later stage.

After spending more than an hour in the largest cave, the group took an elevator to another cave, where research into controlled nuclear fusion technology was conducted.

It is not enough to have a controlled nuclear fusion reactor, but also a more powerful power transmission system, a new type of battery with high capacity and high efficiency, and even reactor miniaturization research and other related technologies need to be developed together, so that the true efficiency of controlled nuclear fusion can benefit all corners of life.

Some of these technologies can be developed by other units. For example, in the transmission system, Huaguo is at the world's advanced level in some fields of power science and technology. They have accumulated enough experience in power supply and transmission, and it is much more convenient for them to complete this work in their own unit than here; of course, the part that is closely related to the controllable nuclear fusion power generation system still needs to be studied by full-time personnel here.

The entire cave forms a black technology research and development center centered on controllable nuclear fusion, which is divided into several groups to carry out synchronous research under the unified coordination of Lu Qiujian, and when the controllable nuclear fusion reactor can operate stably. It is time for other fields to be born, and then China can upgrade its industry with controlled nuclear fusion as the core.

Similarly, the level of security in each area of the cave varies, and each staff member can only work and move in the corresponding area according to his or her own authority, if there is a problem of entering a non-authorized area by mistake. It will be subject to strict scrutiny, which will provide some assurance that the secrets of the base will not be leaked to the outside world.

"I thought that this base would also withdraw from the stage of history like the one in Yuzhou, but I didn't expect it to be revitalized this time! Presumably, many years later, this place will become another shining holy place in the history of China!" After the visit, Major General Li Jiajin said with emotion.

It is estimated that it will become the base camp of villains in Hollywood works, right? Lu Qiujian secretly thought, how will Hollywood describe itself when the time comes? The black hand that is hiding behind the scenes and trying to destroy mankind? Or the hero who leads mankind to the universe? I'm afraid the former is more likely, right?

Today, Lu Qiujian only took a cursory tour to learn about the major progress, and as for other details, Li Yan will stay here and continue to communicate with Major General Li Jiajin to solve them; according to the results of the discussion between the three of them after the visit, Li Yan still needs to stay in the base for about a month.

Stay at the base to rest for one night, and the next day Lu Qiujian left Li Yan behind, and he took Ma Yang to leave the mysterious base in the mountain and go to Chang'an City again, he still has other work to complete.

Whether it is a plasma confinement device for controlled nuclear fusion, or a superconductor is inseparable from a certain rare metal element, after they officially enter the base, with the progress of the experiment, the demand for this rare metal element will be greater and greater, according to the current total production in the international market, can not meet the needs of the project at all, then the current task is to select a few manufacturers, provide them with financial and technical support, so that they can expand production.

Therefore, the first cooperative unit that Lu Qiujian visited was Chang'an Nonferrous Metals Company. (To be continued.) )
