Beneath Deep Space

On the big screen in front, an image like this is being played: This flying saucer is like a flat disk, with the widest part in the middle being about five thousand meters, and its upper and lower height being about two thousand meters.

Underneath one side of the flying saucer, there is a huge hole with a diameter of more than 600 meters! The surrounding metal materials were exaggeratedly dented like broken glass.

In the captain's room, experts are discussing. A weapons expert pointed excitedly on the screen, "After it was hit by a powerful weapon, the entire engine equipment was completely destroyed. You see, the edges of these metals are relatively smooth because they were directly inflated after being hit by a high-energy weapon." Chemical relationship. And this hole is most likely the main reason for the UFO crash!"

"Fortunately, the engine didn't explode after being hit!"

"Also...these long spiral pipes may be ion cannons or laser weapons! Our robot tried it, and the disassembly work was very difficult..."

"Forced disassembly may cause damage to the weapon, but there is another way..."

They discussed loudly that they wanted to use robots to disassemble more useful things. It is difficult to imagine how many years it is beyond human beings. How much they want to get these weapons, people see a little hope and are unwilling to give up no matter what.

"Did you see it? This giant round tube with a diameter of 100 meters is most likely the main gun of the flying saucer! I don't know how powerful it is. It's a pity...it's completely damaged inside and we can't restore it."

"That's right! The inner ring area of ​​the flying saucer is completely closed. Our robot cannot enter for the time being, but we can use this hole. There may be a place leading to the inner area!" An expert had a flash of inspiration and called directly out.

This is quite...

Yu Yifeng's heart also moved. Now that people have been searching for so long, they have found a lot of useful things. Everyone is more eager for the most complete inner ring area.

But people still haven't found a way to the inner ring. Solid gates seem to block all roads. If... this hole is cleared, maybe we can find a way to get in!

This group of people kept discussing until noon before leaving with unfinished content... After Yu Yifeng had lunch, he went directly to the laboratory where Yuriko was.

Yuriko did not join the Wolf Design Bureau or Tesla, but joined the Transhuman Laboratory with her father.

Although the Transhuman Laboratory mainly studies biology, it is also involved in physics and chemistry. It can be said to be a comprehensive research institute. With their abilities, they should be able to gain a good status.

"How's it going? Is the stuff ready?" After being in contact for so long, both parties are relatively familiar with each other. Yu Yifeng was not polite and sat directly opposite Yuriko, picking up a few design drawings and reading them.

Yuriko glanced at him, still focusing on the work on the computer, but she was still distracted and said: "We are roughly ready. Some professional rock climbing ropes are high-strength carbon fiber ropes, very light weight. There are also corresponding ejection hooks. , with the gravity of Mars, the maximum range is more than four hundred meters..."

Yu Yifeng took the special rope and pulled it hard a few times. It was very soft and tough.

He said: "How about the latest space suit? Are there any problems? It must be done as soon as possible. We only have the last few days."

Yuriko nodded, stood up, took out a light spacesuit from a cabinet and handed it to Yu Yifeng.

"There is no problem... This kind of space suit is much lighter than the previous ones, and it has very good radiation protection effect. However, the nanomaterials inside cannot be mass-produced, so the manufacturing cost is very high... According to the previous algorithm , at least more than 60 million US dollars!”

Sixty million dollars? You can buy an airplane at this cost!

Yu Yifeng didn't care about this number. He put on the spacesuit directly and put on the glass helmet. As expected, it felt very light.

When it is filled with air, the clothes will bulge slightly one by one. The whole feeling is equivalent to wearing a cotton coat. No matter what, it is much better than the previous space suits that weighed dozens of kilograms.

Lily Zi looked at Yu Yifeng and said: "There is not much oxygen reserve in the space suit. We must add an oxygen tank at the back to last longer."

She took out another one-kilogram iron can and hung it on Yu Yifeng's back. "One can of oxygen can last about 6-8 hours, so you'd better bring a few more cans. If the spacesuit is damaged, , air will escape quickly from inside, causing the risk of loss of pressure and suffocation... This is the glue and material used for repair, placed in this interlayer, just in case.”

"And this is the injection port for medical products."

The total weight of this entire space suit is about 12 or 3 pounds, which is not particularly heavy. If you get to Mars, you will have to lose two-thirds, and it will be no different from ordinary clothes.

Yu Yifeng waved his shoulders vigorously again and bounced a few times. He still felt that there was a slight obstruction, but it was not too big. He was already satisfied that human technology could achieve this.

After some experiments, he took off his spacesuit again and put it on the table.

"Thank you for your hard work. I'll treat you to French fries another day..." As he said this, Yu Yifeng had already walked out of the laboratory.

Yuriko sat there in a daze for a while, not knowing what she was thinking, but suddenly remembered something: "...wait!"

"What else is there?" Yu Yifeng suddenly heard the shouting and turned back.

She did not take the topic and walked silently to a password cabinet. After entering a set of passwords, the cabinet was completely opened. There was a sealed box inside. She lifted it with difficulty and handed it to Yu Yifeng's hand.

"Let's see!" she said expressionlessly.

Yu Yifeng was not polite and took the box directly. His hand shook and he almost dropped the box to the ground. Fortunately, he reacted quickly and stabilized it in time.

"It's so heavy," was his first thought. According to the feeling just now, it weighs a full thirty kilograms!

What is so heavy? Yu Yifeng thought curiously.

Put the box on the table and open it, you will see a gun with a strange shape. The barrel is very long, about one meter long, with transparent glass on the outside and pipe-like spirals inside, full of weird beauty.

"This is?"

"It should be considered a Gauss rifle, a particle beam weapon. We disassembled it from the remains of some robots, reassembled and modified it. This rifle can easily penetrate high-strength armor!"

Yuriko said calmly: "Due to the limited materials collected, only two were assembled in total. According to calculations, each rifle only has the energy of six to seven bullets. We cannot crack the mystery in a short time. Bullets cannot be replenished..."

Hearing this, Yu Yifeng suddenly became excited and stroked the glass barrel with curiosity. This was a genuine alien weapon!

Although he only had six or seven bullets, he was very satisfied. What an unexpected surprise!

Gauss rifle, a type of particle beam cannon, is also a future weapon that scientists are studying. Its principle is well understood, which is to use an electric field to accelerate charged particles to an extremely high level and then eject them from the muzzle of the gun.

Although it is also a kinetic weapon, the Gauss rifle is much better than modern machine guns. For ordinary firearms, the muzzle velocity of bullets is 300m/s or lower, but this speed can easily penetrate the human body.

The speed of the rifle is higher, about 700-900m/s.

The projectile speed of sniper rifles and heavy machine guns is even higher, around 800-1000m/s. This speed can penetrate the armor of some tanks!

But the speed of the Gauss rifle is completely higher by more than an order of magnitude!

Yuriko smiled slightly on her face and said: "It can eject a series of charged protons, and the speed of each proton is close to the speed of light... about 0.9 times the speed of light. Because the battery energy of the gun itself is limited, we have no way to replenish it. , so it only has the energy of six bullets.”

"Although only dozens or hundreds of protons are ejected, each proton can easily overcome the Coulomb repulsion between nuclei due to its extremely high speed and hit the target's atomic nucleus level. When the protons forcefully squeeze into the atomic nucleus, they interact with the atomic nucleus. When a collision occurs, a small nuclear fusion occurs."

"A string of high-energy protons will release an energy equivalent to the explosion of 20-30 kilograms of TNT!"

Hearing this, Yu Yifeng opened his mouth. What an incredibly powerful weapon!
