The blue lights flickered, and the elevator descended quickly downward.

Soon, the red indicator light jumped green, and the elevator stopped at the bottom 1,000 meters below. Walking to the gate of the shelter, Jiang Chen entered a few passwords on the door, then pulled out the data cable inside and connected it directly to the EP.

[Genetic code confirmed, welcome back, Mr. Manager.] 】

[The shelter gate is activating ......]

Jiang Chen ripped off the data cable and took two steps back. Soon, with a dull sound, the round door panel in front of him slowly moved sideways. Behind that gate, Xu Lu, the executive officer of Camp 27, was already waiting there.

Seeing Jiang Chen, she bowed with a smile and welcomed Jiang Chen into the shelter.

"The xenotide is over, let's arrange for someone to return to the surface. ”

"So fast?" Xu Lu said in slight surprise, but soon she regained her smiling appearance, "I'll go and prepare." ”

After saying goodbye to Xu Lu, Jiang Chen took the two guards behind him and walked straight to the Mechanical Research Institute in Vault 27, and found Fang Weixian who was immersed in drawing.

"Marshal, why are you here in person? Fang Wei first pushed away the drawing tablet in his hand and greeted him with a smile.

"Well, there's something I'd like to show you, and then I'll refer to your suggestion. After speaking, Jiang Chen gestured to the guards behind him.

The guard nodded, put the two boxes he was carrying on the table, and then retreated behind Jiang Chen.

"This is?" Fang Weixian frowned slightly, walked to the edge of the box, and reached out to open it.

After seeing the contents of the box. He was stunned at first, and then he was surprised.

"Mechanical exoskeleton...... Gauss rifles?!"

"Comes with an optically invisible mechanical exoskeleton. Jiang Chen added.

There was a gleam of interest in his eyes. Fang Wei first reached out and rummaged through the fragments of this mechanical exoskeleton, and then looked at the wreckage of the Gauss rifle.

"I want you to restore the technology in this. Can you do it?"

"I can give it a try, it shouldn't be too difficult. Fang Wei first moved the two boxes next to a scanner, "scanned the construction of the parts, restored the missing parts, and then used a quantum computer to simulate the design and finally set up the production process." ”

"Can it be mass-produced?" Jiang Chen asked.

"It's not easy. Fang Weixian shook his head, "Many things can only be recycled, such as the Type 50 electromagnetic cannon in the base, many of the parts in it cannot be produced by themselves from beginning to end. If no parts are recovered. Only 3D printing technology can be used. ”

The 3D printing technology of the 22nd century is quite mature, and there are no strength, precision and material limitations faced in the early 21st century. However, even so, 3D printing technology is still an expensive technology. For example, if a Ripper rifle was produced on a normal military production line before the war, it might cost less than $10,000, but if the rifle was made with 3D printing, it would cost at least $100,000 and would not increase the cost due to increased production.

On the wasteland, because of the collapse of the industrial system. The survivors also used 3D printing technology for some parts that could not be machined. Just like a T-3 power armor, at least 6,000 out of 10,000 parts are produced by 3D printing technology and then assembled by hand. This is exactly why power armor is so expensive.

"If you use power armor to produce a Gauss rifle, what do you estimate to be the approximate cost?" Jiang Chen asked casually.

"The main cost is reflected in energy consumption and material loss. If it is produced entirely by 3D printing technology...... About 4,000 crystals for a rifle. The miniature high-energy capacitors inside, as well as the acceleration track, are very demanding on the materials. Fang Wei first gave an estimate.

Boy. It's almost half the size of the T-3 power armor. Jiang Chen said secretly.

Jiang Chen pondered for a moment before he spoke, "No matter what you say. You restore the technology first. A little more expensive is a little more expensive. ”

In addition to its use in aviation, this Gauss rifle is also very effective against power armor. its penetration and stability. None of them can be compared to traditional rifles.

Finally, after inspecting the production of chariots in the Lower Machinery Research Institute, Jiang Chen left here without disturbing the technicians in the research institute.

Leaving the Mechanical Research Institute, Jiang Chen then went to the Biological Research Institute, which was not far from here, and found the biological scientists who were not very well received in the shelter. When Jiang Chen walked into the research institute, he saw that the scientists in white coats were pointing around a culture tank, their faces filled with creepy excitement.

As for why they are creepy, it's all because they look too much like Frankenstein in comics.

The study of life has always been a taboo in the field of science, and its danger is no less than that of advanced artificial intelligence. However, in the wasteland, all scientific laws no longer apply, so they have the ability to use their imagination freely.

"What are you looking at?" Walking behind Wang Fangping, Jiang Chen patted him on the shoulder.

Wang Fangping was startled, and when he saw that it was Jiang Chen, he smiled, "Marshal, the power generation seaweed you ordered us to study has been completed." ”

"Done?" Jiang Chen was stunned for a moment, and then a happy expression appeared on his face.

If the new country wants to develop tourism, it must reduce the number of thermal power stations as much as possible. However, the efficiency of wind and solar power generation is too low, and the cost of tidal power generation is too expensive, so there is no need to think about nuclear power plants, so Jiang Chen has always maintained a strong interest in Wang Fangping's biopower generation technology.

Not only is it environmentally friendly, but it is also cheap, and the last thing that Pacific countries lack is the area of territorial waters.

"This is it. Wang Fangping stepped aside and smiled and made a gesture of please to the culture tank.

I saw a 3-meter-long piece of seaweed floating in the yellow-green culture tank, and ultraviolet lamps hung above the seaweed. A meter next to it records the ratio of the amount of light to the amount of electricity generated by the seaweed.

"It can be planted in water at a depth of 100 meters with a maximum power of 1 kilowatt per square meter. Seaweed roots can be connected to wires to deliver electricity to shore transformers and then fed into the grid. Wang Fangping pointed to the meter and explained to Jiang Chen.

Jiang Chen nodded with satisfaction: "Very good, you did a good job." All participating researchers will be rewarded with 1,000 subcrystals each!"

Hearing this, the nine scientists in the institute were all happy.

1000 subcrystals, you must know that the salary of the NAC knight is only 50 subcrystals per month, and this 1000 subcrystals is undoubtedly a huge amount of money. Jiang Chen has never been stingy with his investment in scientific research.

"Marshal Xie!" Wang Fangping took the lead and said gratefully.

"You're welcome, I don't skimp on rewards anyone who has contributed to NAC. By the way, I still need you to help me with something. I need your help me to breed a xenomorph that is less aggressive, easy to raise, and can quickly accumulate subcrystals. Jiang Chen put forward the main purpose of this trip.

Now that the plan to "clean up" Wanghai City has been determined, the source of the subcrystals has to find another way.

Convert all hunting groups that have developed from hunting to serve as mercenaries escorting caravans, then change the source of subcrystals in the factory from "hunting grounds" to "pastures", and establish an Eden ecoregion in the wasteland to produce food.

Jiang Chen has already sketched out this blueprint in his heart, and the first step to realize this plan is to find different species suitable for captivity! )

PS: Weak for a monthly ticket, we have rushed to the classification 14, as long as 4 more chrysanthemums are exploded, this book will be able to show its face in the classification list!
