On the big screen in front of it, an image was playing: the flying saucer looked like a flat disk, the widest part of the middle was about 5,000 meters, and the height of the top and bottom was about 2,000 meters.

Underneath the side of the flying saucer, there is a huge hole with a diameter of more than six hundred meters! The surrounding metal material is exaggeratedly sunken into it like broken glass.

In the captain's room, experts are talking. A weapons expert excitedly pointed 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 of the direct vaporization after being hit by a high-energy weapon." And this hole is most likely the main reason for the UFO crash! ”

"Luckily, after the engine was hit, it didn't explode!"

"And ...... These long spiral pipes could be ion cannons or laser weapons! Our robot tried it and the disassembly was very difficult......"

"Forced disassembly can lead to damage to the weapon, but there are other ways ......"

They discussed loudly that they wanted to use robots to disassemble more useful things, and it was hard to imagine how many years ahead of humanity were. How much they want to get these weapons, people see a little hope, and they are not willing to give up no matter what.

"See, this giant round tube with a diameter of 100 meters is very likely to be the main gun of the flying saucer! I don't know how powerful it is, but it's a pity...... The inside is completely damaged, and we can't restore it. ”

"That's right! The inner ring of the saucer is completely closed, and our robot can't get in for the time being, but we can use this hole, and there may be a place to open to the inner area! An expert had a flash of inspiration and called out directly.

That's right......

Yu Yifeng's heart was also moved, now that people have been looking for so long, they have found a lot of things that are useful again, and everyone is even more eager for the most complete inner ring area.

But people still haven't found a way to the inner ring, and solid gates seem to block all roads. If...... Clear this hole, maybe you can find a hole to get into!

The group discussed until noon before leaving...... After Yu Yifeng ate lunch, he came 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 the direction of biology, it is also involved in physics and chemistry, and it can be said that it is a comprehensive research institute, and with their ability, they should be able to obtain a good status.

"How's it going, is it done?" After being in contact for so long, both sides are relatively familiar. Yu Yifeng was not polite, he sat directly opposite Yuriko, picked up a few design drawings and looked at them.

Yuriko glanced at him, still focused on the computer, but still distracted, "Roughly ready." Some professional climbing ropes are high-strength carbon fiber ropes that are very lightweight. There is also a corresponding ejection hook claw, with the maximum range of Mars' gravity above 400 meters......"

Yu Yifeng took the special rope and pulled it a few times, both the softness and toughness were very good.

"What about the latest spacesuits, and what are the problems?" he said. It has to be done as soon as possible, we only have the last few days. ”

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

"No problem...... This spacesuit is much lighter than the previous ones, and it has a good radiation protection effect. However, the nanomaterials in it cannot be mass-produced, so the manufacturing cost is very high...... According to the previous calculation, at least more than sixty million dollars! ”

60 million dollars? This cost can buy an airplane!

Yu Yifeng didn't care about this number, he directly put the spacesuit on his body, and then put on a glass helmet, which really felt very light.

When the inside is filled with air, the clothes will bulge slightly one by one, and the whole feeling is equivalent to wearing a cotton coat, no matter what, it is much better than the previous spacesuits weighing dozens of kilograms.

Yuriko looked at Yu Yifeng and said, "There is not much oxygen reserve in the spacesuit, and an oxygen tank must be added to the back to last longer." ”

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

"And this one, it's the injection port for medical products."

This whole set of spacesuits adds up, almost twelve or thirteen pounds, which is not particularly heavy, and if you go to Mars, you will have to lose two-thirds, which is no different from ordinary clothes.

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

After some experimentation, he took off his spacesuit and placed it on the table.

"Thank you for your hard work, I'll treat you to french fries another day......" In the voice of the voice, Yu Yifeng had already walked out of the laboratory.

Yuriko sat in place for a while, not knowing what she was thinking, and suddenly remembered something: "...... Wait a minute! ”

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

She didn't take the topic, and walked to a locker in silence, and after entering a set of passwords, the cabinet was completely opened, and there was a sealed box inside, she struggled to lift it up and handed it to Yu Yifeng.

"Check it out!" She said with a blank face.

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

"It's so heavy", that was his first thought. According to the feeling just now, it weighs a full 30 kilograms!

What is so heavy? Yu Yifeng thought curiously.

I put the box on the table and opened it to see that it was a gun with a strange shape. The barrel is very long, about a meter long, and the outside is transparent glass, and the inside is covered with pipe-like spirals, which is full of strange beauty.

"What is this?"

"I think it's a Gauss rifle, a particle beam weapon that we dismantled from the wreckage of some robots and reassembled and reassembled. This rifle can easily penetrate high-strength armor! ”

Yuriko said lightly: "Due to the limited materials collected, only two were assembled. According to calculations, each rifle has only six to seven rounds of energy in it. We can't solve the mystery in the short term, and the bullets can't be replenished......"

Hearing this, Yu Yifeng suddenly became excited, and stroked the glass barrel with a curious expression, this is a genuine alien weapon!

Although there were only six or seven rounds of ammunition, he was also very satisfied, what an unexpected surprise!

The Gauss rifle, a type of particle beam cannon and a future weapon that scientists are working on, is easy to understand, which is to use an electric field to accelerate charged particles to an extremely high point and then eject them from the muzzle.

Although it is also a kinetic weapon, the Gauss rifle is much more powerful than the modern machine gun. The muzzle velocity of a bullet is 300 m/s or less in a typical firearm, but this velocity can easily penetrate the human body.

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

Sniper rifles and heavy machine guns have a higher projectile velocity, around 800-1000m/s, which can penetrate the armor of some tanks!

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

Yuriko smiled slightly and said, "It can shoot a series of charged protons, each of which is close to the speed of light...... It's 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 we only have the energy of six bullets. ”

"Although only dozens or hundreds of protons are ejected, each proton can easily overcome the coulomb repulsion force between nucleons and hit the nucleus level of the target because of its extremely high speed. When a proton is forcibly squeezed into the nucleus, a small fusion occurs when it collides with the nucleus. ”

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

Hearing this, Yu Yifeng's mouth grew, it was really a powerful and incredible weapon!
