The last memory that the big man who didn't even leave his name for Xiao Chu was a machine the size of a mobile phone. The level of technology is unknown, but the operation is very simple, as long as it is a human image, it is automatically recognized and bound. Immediately it became a special equipment for Xiao Chu.

Comes with a screen, the screen is very sci-fi, it is directly a piece of glass that can be lifted, and the glass will become opaque after showing something.

Open the directory, and it's almost the same as the operating system on Earth. And it's also very humane to translate it into a Chinese version.。 It is estimated that at that time, they saw that their language habit was Chinese. Nonsense, the Taoist priests are out, what are not Chinese characters?

It's not big, but the storage capacity is quite amazing, and it has reached the level of 1YB. More than all the human memory tied together today. But it turned out that it wasn't a product of Earth, but an acquired extraterrestrial storage.

It not only contains the application of science and technology, but even literary and artistic works such as poetry and painting are preserved and classified one by one. And these things are the ones that occupy the vast majority of the reserves.

"Hello, although I still don't know what your name is, little Taoist. My name is Chu Feng, the commander of the 1st District of the Planetary Federation. When you read this passage, we should fight on the battlefield of life and death. We've bought ten of these storage devices, and each one is worth more than 100,000 energy points. Seeing the original big man appear on the screen of this device again, Xiao Chu felt sad for a while, he is still a family.

"It stores the relatively safe scientific and technological information we have screened, as well as the spark of our culture, and I hope you can help us pass it on. At the same time, there are also some interstellar expeditions with four other storage pieces flying to places in the depths of the stars that we have never explored before, and we are trying to reach other civilizations, even though we have long been able to fly into deep space. Hehe. Speaking of this, Chu Feng couldn't help but smile self-deprecatingly. Don't laugh at us for being cowardly, the more we know about this universe, the more we are afraid, and I hope you have not lost the courage to explore. Some of the other storage pieces are buried deep in the depths, and some have established safe bases to place them, with the intention that survivors will be able to get them in the future, and it is not necessary to develop a civilization again. Another piece we threw into a space-time rift that we stumbled upon us. Maybe it will be mastered by people from the other world. But it doesn't matter, anyway, we are also facing a war of extermination, if there is a chance. Let's get in touch again, cherish. ”

The video is disconnected, it is a stored video, not an instant messaging. But Xiao Chu found that he was a little sad.

I haven't felt this feeling for a long time, since observing other people's seven emotions and six desires, Xiao Chu, as a high-level observer, has long buried his true emotions, sad? It's been a long time since I've felt this way.

Dark matter engines, also known as dark matter energy engines. In fact, it is no different from a boiler, except that some dark matter that cannot be distinguished by the naked eye, but can be captured by special instruments, is taken to the so-called machine and burned, and then a large number of ordinary material particles are produced, which can carry out various energy outputs, gather together to become electric ions, which can produce electricity, and then disperse into particle streams, which can produce a higher level of jet energy than electricity. Jet energy can provide a lot of kinetic energy, even in the void, and can provide strong thrust. As a result, the main role of the dark matter engine turned out to be a power source for spacecraft.

In fact, the greater role of dark matter is at the weapon level. In the face of the power of semi-liquefied dark matter bombs formed by dark matter, nuclear weapons are probably children. Chu Feng didn't tell the truth, their destruction technology was actually much more developed than the current earth. Nuclear weapons will become incomparably weaker in the history of their development. Because even more powerful than them are the Dark Matter Destruction Bomb.

An existence that can directly annihilate all the matter in the area. Let all matter be reduced to the most basic energy state.

It's amazing, but it's a pity that because of this kind of thing that can easily destroy a planet, this electronic storage device is directly shielded, and it is not a dying moment, and the parameters and manufacturing methods of this weapon cannot be retrieved. And Chu Feng also left a message here, if their world really comes to the last step, when the security officers in the security tower find that the whole world cannot be saved, they will detonate the dark matter annihilation bomb made with the power of the whole world, and destroy it together with all the evil spirits.

Well, let's explore it slowly, and they are kind enough to give the basic technology.

Especially in terms of materials science, many new alloy materials make Xiao Chu's eyes shine.

It's a pity that you can't just take it out.

If any kind of super alloy is exposed, it is most likely that it will be decomposed by its current lovely motherland. The properties of these super metals are simply too powerful.

Technology on Earth has been confined to Earth for decades, why?

Earthlings have long been able to fly freely in space, so why are they still wandering around the earth and only sending those few astronauts every year?

Because the basic material technology on the earth has not caught up with the pace of theoretical technology, it is too far behind.

For example, in ancient war technology, with bronze tools, the Stone Age could be crushed, and in the Iron Age, a warrior in iron armor was simply immortal, and the iron-armored warriors of the Han Dynasty could easily crush the steppe Turks who were much stronger than them. The steppe people's rudimentary weapons could not kill the heavily armored Han Iron Horseman.

And in the Tang Dynasty, with the evolution of piercing weapons, iron armor was not unbreakable, especially with the emergence of stainless steel, iron armor became a chicken rib again.

Until thousands of years in China, nothing has changed much.

In Europe, due to the appearance of full-body steel plate armor, ordinary weapons were no longer able to break through defenses.

And so on and so on, until the guns appeared.

But in the end, the gun also encountered the object that was crushed, and that was the tank. Thick tanks, not to mention guns, are difficult to penetrate even guns.

This continued until the advent of anti-tank guns.

But don't think that anti-tank guns are invincible. Later, after the appearance of composite armor, people suddenly found that a large number of anti-tank guns had also become chicken ribs.

Now, many countries claim that our main battle tanks can completely defend against armor-piercing shells below a certain millimeter, which is not just talking, that is, it can really defend.

RPG？

The most powerful version of this thing now doesn't want to penetrate the front and side armor of the main battle tanks produced by the Big Five. Of course, in the case of a certain earth country letting people serve a pot of leopard two at once, it was all a chrysanthemum stabbed. The question is, how much of a wastewood army does it take for the infantry to easily stab the chrysanthemums of several tanks? What about the Tactical Circle of Defense? What about the step-tan synergy? Therefore, no matter how good the weapon is, it depends on who uses it.

Now that science and technology have developed to this extent, an era in which the attack completely overwhelms the defense, there is a great need for a material that can prevent the crushing and overwhelming attack.

Is there any?
