"Some scientists have made a report on your space shuttle." Wang Cheng said, "China's existing technology is not that it can't add energy to your space shuttle, but the problem is that the cost is too high."

"What do you say?" Fang Ze asked curiously.

"It's similar to charging Apple mobile phone with universal charge. The method is feasible, but not to mention permanent damage to the charging device of the space shuttle, and the charging efficiency alone is very low. Coupled with the loss in the charging process, the country has to use enough electricity in a city like DIDU for a year to fill your space shuttle. So don't think about it until we have a mature nuclear fusion power generation device. Throw it in." Input is not proportional to output. "

Every great progress of mankind is accompanied by a great revolution in energy.

The electricity consumption of a factory in modern society was enough for all factories in a country at the beginning of the industrial revolution.

So with the technological level of the space shuttle, the energy it needs is really a great burden for China today.

Fang Ze touched his chin and thought about the works of technology that can build nuclear fusion power generation devices in the background setting. It seems that humans in StarCraft can achieve it. However, in the background story of StarCraft, the resources used by the three races are crystal and gas, so the Terrans may not have mature nuclear fusion energy devices suitable for the earth.

With the sound of the wall moving, the huge elevator slowly stretched out from the ground, and then Fang Ze motioned Wang Cheng and the agents to come in.

"Is there an elevator in the basement? It's too extravagant." Wang Cheng stood on the elevator and looked at the spacious elevator, which can transport about 20 people at one time. He was a little confused about Fang Ze's luxury of equipping the basement with such an elevator.

"Well, I repaired the basement a little deeper, so it's faster to take the elevator." Fang Ze refrained from giving Wang Cheng spoilers about the scale of the underground base of the demon Management Bureau in advance.

After everyone entered the elevator, the elevator door closed slowly, and then the elevator began to drop with more than a dozen people.

Although Wang Cheng's office is not on the top floor of the building, he usually goes upstairs and downstairs without taking the elevator. But he often runs everywhere and is no stranger to the speed of high-rise elevators.

Generally speaking, an elevator with a height of 20 or 30 floors will arrive in ten seconds if it doesn't stop in the middle.

But now he was sitting on the elevator to the basement in fangzekou. After a full minute, the elevator was still falling, and the agents around him felt something was wrong.

"Fang Ze." Wang Cheng hurriedly looked at Fang Ze and asked, "how deep underground have you built a basement?"

"I don't know, about hundreds of meters?"

"Hundreds of meters?" Wang Cheng looked at Fang Ze and shouted, "how long has it been? Tell me hundreds of meters and thousands of meters. I also believe it."

"Don't worry." Fang zegang wanted to say something. After a soft Ding, the elevator of the demon Administration Bureau finally stopped.

"You see, this is it?" Fang Ze pointed to the slowly opened elevator door and said.

"Let me see how big your basement is." Wang Cheng finally realized that there was something wrong.

For Fang Ze and his demon Management Bureau, any common sense judgment will not work.

The only reason why he built the basement so deep is that the area of the basement is too large. If it is not built very deep, it is easy to cause ground collapse.

After the elevator door was fully opened, Wang Cheng was the first to go out.

Of course, what appeared in front of him was not the large basement he imagined, but a very ordinary looking room with a thick blanket on the floor, which was very comfortable to step on.

This is the welcoming place and the first line of defense of the demon Management Bureau. If it's not your own person who comes in, the room will immediately drop heavy iron plates, completely trapping the enemy in the room and unable to go out.

At the same time, the elevator will rise at the first time and lock the elevator shaft to prevent the enemy from escaping.

But Wang Cheng didn't know this. He was just curious about what kind of world would appear after he opened the door of this room.

A huge underground base like a factory?

It is also an underground residential area with dense rooms and dim lights.

In view of the fact that the power consumption of the whole Xihe street has not increased much after Fang Ze built the basement he talked about, Fang Cheng believes that his guess is still very reliable.

Without solving the energy problem, the underground base secretly built by Fangze will certainly not be too large.

With this in mind, Wang Cheng pushed open the door of the room.

Except for the residential area on the second floor of the underground base of the demon Administration Bureau, all the elevators directly to the ground are located on the side of the corridor next to the artificial sun of the underground base of the demon Administration Bureau.

So when Wang Cheng pushed the door open, he saw that the artificial sun like a real sun was emitting soft light, and countless solar crystal panels were laid on the corridor wall around the artificial sun to produce electricity.

This is the reason why the underground base of the demon Management Bureau does not need to transmit electricity from the ground.

The energy produced by the artificial sun is enough for this underground base, which currently consumes little, to use for thousands of years.

At this moment, Wang Cheng thought he had crossed.

No one dares to think that such an underground base like a small town is hidden under the huge city of DIDU.

Nearly 10000 people here live, work and study some taboo technologies that can't be found on the table. If this base is in the hands of the state, Wang Cheng can imagine that this will be the place where China's state secrets are stored most.

"Cough." Fang Ze pretended to cough, then walked behind Wang Cheng and said modestly to Wang Cheng, "how about my underground base?"

"Yes, but can you answer me a few questions?" Wang Cheng turned his head, and the shocked expression on his face had returned to normal.

Fang Ze thought that Wang Cheng wanted to ask how the huge base was built, so he said, "ask first, and I'll try to answer you."

"Has your underground base gone through strict geological exploration, applied to the planning, land and construction departments of the imperial capital for construction, and whether the relevant design drawings have been approved and reviewed by the relevant management departments, and whether the sanitation and fire inspection have been inspected and supervised?"

"Well." Fang Ze looked at Wang Cheng who said these words seriously and asked, "what do you want?"

"I mean, I suspect that your underground base is an illegal project. All the buildings here are illegal buildings, so should you do something?" Wang Cheng said with sly eyes.
