After finding a place with few people, Xu Cheng flew directly at supersonic speed and hurried to the Pangu Science and Technology Factory. When I arrived at the place, I found that I was already waiting on the playground with a Wind Roar 8 helicopter.

Seeing Xu Ying falling from the sky, Pian Feng didn't talk nonsense, and asked him to board the plane, and then Wind Roar 8 quickly rose into the air and flew away to the northwest.

"Where are we going?" Xu Cheng couldn't help but ask.

"Black Great Wall Research Institute."

Xu Cheng thought about it, the Black Great Wall is a top-secret project, and its location and information are a mystery to the outside world. In the anime, after the outbreak of the Great War, neither gluttony nor demons seemed to have discovered its whereabouts at first. If it is found, destroy it in one fell swoop, and it will be even more difficult for the earth to resist.

In the later period, almost all the weapons invented by Ge Xiaolun were produced by the Black Great Wall, and the famous Mangdangshan was the result of the second phase of the Black Great Wall.

Through the Book of Heaven, Xu Cheng saw the fate of some people, and faintly discovered the location of the Black Great Wall from their fate.

To his surprise, there were three places on the Black Great Wall.

One is the Black Great Wall Research Institute that Lian Feng just said.

One is the top-secret engineering headquarters of the Black Great Wall of the Giant Gorge.

One is the Black Great Wall manufacturing base, where the future Mangdangshan is located and the core of the Black Great Wall.

Wind Roar 8 flew out of the jurisdiction of Juxia City and gradually entered the territory of other provinces. I saw that in the reckless mountains, there is a large-scale building complex, these buildings are more dilapidated and decayed than those in the Pangu Science and Technology Factory, the walls are collapsed and the houses are leaking, the weeds are overgrown, and they are higher than the human roof, swaying in the cold wind in winter, showing the meaning of withering and yellowing, and you can see that it has been abandoned for many years.

The high-speed rotating propeller brought up a strong air current, blowing the dead branches and weeds in all directions, and the concrete floor at the landing site suddenly separated to both sides, and the helicopter continued to descend, landing on a high platform. I heard a few clicks, and the concrete floor that had been separated above slowly closed.

Lian Feng and Xu Cheng stepped off the helicopter, and the former said as he walked: "This was originally the earliest space base in Chixian Shenzhou, and later the base was moved to the mainland, and some scientists stayed behind to form the Black Great Wall Scientific Research Institute to carry out some supporting scientific research activities. ”

Xu Cheng smiled: "The place is quite remote, if I were an intruder, I would not have thought that there would be a hole in this place without being able to read other people's secret information." ”

Lianfeng asked curiously, "Don't you know either?" ”

"One of three places."

Mercy shut up.

Under the platform is a scientific research place full of science fiction, with uniformed researchers and flashing instruments, which makes Xu Cheng have a dreamy sense of traveling through time and space.

"Chief of the Wind!"

"Is the White Hole working properly?"

"Everything works."

Lian Feng nodded, and said to Xu Cheng quite mysteriously: "Xu Cheng, take you to see some good things." ”

"What's good?"

"You'll know when you see it."

Xu Cheng was suddenly a little curious, and followed Lianfeng through a door and entered a huge space, or an industrial area, and the scene in front of him made Xu Cheng's eyes glazed and shocked.

It is a behemoth, about 155 meters in length and 60 meters in width, all of which are integrated, say it is a metal box, and there are hundreds of workers and robots around to add materials to it, and then spit out the finished parts from the other end, there are many kinds of finished parts, and there are hundreds of kinds of parts that Xu Negative has seen, and there are more that have not been seen.

Xu Cheng reacted and said in surprise: "This is a 3D printer? ”

Lian Feng smiled and said: "You call it a 3D printer, a universal factory, we call it a white hole, just like a white hole, it can continuously spit out matter." Theoretically, as long as there is enough energy and sufficient materials, this white hole is fully functional, and can quickly produce thousands of parts, which can be used to assemble all types of machine tools and machines on the earth, and the quality and precision are far beyond the world level. ”

"Good stuff! Good stuff! Xu Cheng was about to laugh when he saw it.

Lian Feng looked at him like this, and couldn't help but smile: "Actually, this white hole is nothing, we have another one that is more advanced than it, the material uses biotechnology, uses organic matter and protein as components, has a powerful sensing system and self-healing ability, can continue to run stably for thousands of years, and there is no need to change parts during the period." This metal machine is not good, and it is very troublesome to replace parts every once in a while. ”

"Of course, these two white holes are not the top technology of the Deno civilization, they belong to the things that have been eliminated a long time ago. After we came to Earth, we remanufactured them based on the development trend of science and technology and the earth's resource reserves, and cooperated with the super gene implantation and auxiliary Black Great Wall project. ”

Ma Ma batch, Xu Cheng was shown by her.

Not to mention the white hole that I have never seen in the main base, let's just say that the one in front of me may not be able to be made by the earthlings in fifty years, and Xu Cheng himself has little confidence, after all, the science and technology of the last catastrophe of human beings is actually quite biased, focusing on life sciences, mechanical engineering, materials science, computers, software, artificial intelligence, etc.

A white hole that happens to cover most disciplines.

How?

Looking at the big guy in front of him, Xu Cheng seemed to understand why the Black Great Wall had such a strong production capacity. In the early stage, the Mangdangshan was built, and in the later stage, Ge Xiaolun handed over the invented weapon drawings to the Black Great Wall, and the Black Great Wall was built in batches without much time. This can't be done at all without a strong production capacity, and not everyone is Ge Xiaolun who has the ability to fight against the Void.

"Lao Du is confused!"

"What?"

Xu Cheng said bitterly: "You have such a good thing, why don't you take it out and use it, if you explode a wave of weapons and equipment, the chances of winning will be a little greater." ”

Lian Feng defended: "Xu Cheng, you think things are too simple, first of all, the operation of the white hole needs to consume a lot of energy, where does the energy come from?" We'll all have to turn to the Sun Star for help. Secondly, the products produced by the White Hole are very low-end things, which have long been eliminated by the Deno civilization. If you don't say it, we can't imagine that an astronautical civilization would launch a ground invasion war against a pre-nuclear civilization, which is too unscientific. With the technological gap between the two sides, the space civilization has the ability to destroy the earth outside the atmosphere and human beings resist. ”

Based on this understanding, the Black Great Wall in the anime slammed the Mangdangshan and various advanced dark alloy equipment, ignoring the production of low-end weapons and equipment, and was crippled by a wave of gluttonous civilization.

Can't be wrong.

On the contrary, Xu Cheng took it for granted, the gluttonous civilization is also an aerospace civilization, the level of science and technology is one level higher than that of the earth, and Morgana's demon civilization is a super-god-level civilization, the two sides are not in the same order of magnitude at all, and low-end weapons may not be able to play a decisive role.

Coupled with the lag in intelligence and the lack of the ability to disappoint such foresight, Dukao, out of repentance for the war, was too conservative and it was normal for him to make mistakes in decision-making.

"It's only been nine months, and I don't know if you'll be in time."

"Just in time." Lian Feng said affirmatively: "Rena provides us with stellar-level energy, and with the support of the state, it is very fast to use the white hole to produce low-end weapons and equipment. We are now manufacturing production line equipment for weapons such as the Dawnlight Improved Aerospace Fighter, Gonggong Power Armor, Shadow Blade Laser Gun, Thor Electromagnetic Gun, and more. ”

“what？” Xu Cheng looked at Lian Feng dumbfounded, "You have all started to produce these weapons?" ”

Lian Feng said as a matter of course: "It's a very low-end thing, just take it out in your head and use it." ”

"And what did you call me for?"

"Didn't you say you wanted to get involved?"

“……”
