Anyway, Liu Xuan will soon be able to get the technology that their civilization expects, Liu Xuan followed the old man closely, for fear that he would lose the old man, after going through so much, if he lost the old man, Liu Xuan would really have no place to cry. At this time, Liu Xuan was more cautious than before.

This door is obviously also a space, Liu Xuan followed the old man to a special, very small space, this space is designed like a treasure trove. In fact, for Liu Xuan, this is indeed a treasure trove, after all, there is the technology they need, and there is the key to the continued survival of their civilization.

In the middle of this room, there are indeed two things that look quite important, although there is no protection visible to the naked eye, but Liu can feel the killing machine hidden in the secret, obviously, there are some protective facilities here, but Liu Xuan himself can't see it.

In fact, even the old man is cautious, even if the civilization that has mastered this technology is quite cautious, it seems that this place is indeed quite dangerous, and it is a danger hidden in the shadows, sometimes, or most of the time, the danger that cannot be seen is the most dangerous, obviously, this time Liu Xuan is facing such a danger.

I can't see it, but it is real, like a poisonous snake in the dark, lurking cautiously, waiting, when the prey appears, it will not hesitate to give its prey a fatal blow, just looking at the old man's nervous expression, Liu Xuan also understands how terrifying the poisonous snake hidden in this place is.

"Good observation, just by looking at my movements, you can know that there are a lot of dangers hidden in this space." Just when Liu Xuan was cautiously looking around, carefully looking for the location of the mechanism, the old man suddenly turned around and grinned at Liu Xuan, it seemed that he had already understood what Liu Xuan was thinking.

Liu Xuan's face froze, he was almost a little confused, could it be that this civilization has any technology to probe the true thoughts of human beings, when we talked just now, many of Liu Xuan's thoughts were also seen through by this old man, and now it is like this, if it turns out to be a coincidence, then the coincidence is too simple.

"Don't think about it, we do have the kind of technology you want, but only the technology has no finished product, after all, we are all creatures, and there is no creature who wants the other party to know their true appearance, which is also a violation of our own privacy, so we will not be idle and have nothing to do with this kind of bells and whistles technology."

Liu Xuan didn't speak, but the old man seemed to know him quite well, Liu Xuan simply wrote his disbelief on his face, after all, his thoughts were completely guessed by the old man every time, and it was quite normal for Liu Xuan not to believe that he didn't have that kind of technology.

"I just don't believe it, my idea is guessed by you almost every time, you say there is no such technology, do you think I believe you?" Liu Xuan also expressed his attitude and refuted what the old man said just now, after all, the old man guessed too accurately, and Liu Xuan didn't get along

Belief is quite normal, this is human nature, and a normal person will think so.

"Hehe, this is really like a young man, do you know my real age? If you knew, you wouldn't think so, the old man is generally quite accurate in seeing people. Especially an old man like me. The old man didn't show any objection to Liu Xuan's disbelief, just like an old man on the earth, putting on his own old man's shelf.

"Hundreds of years old, it doesn't look like it, but have you also cracked the mystery of life and obtained the secret of longevity? It's also possible. Liu Xuan said to himself, thinking about it, according to the scientific and technological level of this civilization, there is indeed such a possibility, after all, this is a civilization that is infinitely close to the sixth level.

"Yes, you're right, we've already gained the secret of longevity, but we rarely use this kind of technology, and when you reach our level, you'll also find that there are some natural laws, you don't have to master them yourself to be the best, natural is good. We have lived a long life ourselves, and there is no problem in living to be 300 years old, and my real age now is 260 years old. The old man smiled slightly, and reported an age that was enough to make Liu Xuan's jaw drop, this civilization is simply like a turtle on the earth. The difference is that the turtle does not have such a high level of technology.

Although I was very surprised by the old man's words, I agreed with the old man's words, the emergence of some technologies is the beginning of a disaster in itself, and whether we can recognize the true face of these technologies may also be a sign of civilization and progress.

Take the earth civilization as an example, if the current earth civilization is really the technology to achieve longevity, many rich and powerful people will not be able to bear it, this kind of technology that violates ethics and morality can be studied, but it is best not to use it in real reality, this is what the old man said: sometimes it is very important to conform to nature.

"Okay, let's talk more, this can be regarded as a piece of advice to you, technology and morality are synchronized, once technology and morality are derailed, for a civilization, it is a disaster, the beginning of a downfall. Technology is a double-edged sword, there is no doubt about it, it is up to the person who controls what he does. The old man smiled and stopped the topic just now.

"So are these two things technology or something else?" Liu Xuan also took the opportunity to change the topic and guided the topic to the two things that seemed to have no protection, but were very dangerous. Anyway, Liu Xuan's purpose is them, and what he wants is also theirs.

"The protection problem here just now, there is indeed a danger here, there is a danger that I dare not approach, I can't see, although it is not a key important technology, but such preservation is not an exaggeration, after all, these are two very important basic technologies." The old man still wanted to show Liu Xuan the defense of this place.

The old man's palm flipped over, and he didn't know that he took out a metal block in the shape of that, and looked at the old man's hand sinking

, This thing is quite medium, such a volume with a not light mass, you can imagine how dense this thing is, you can imagine the toughness of this thing.

"It's a metal that's unique to our planet, and it doesn't matter what the name is, you just need to know that this thing is something we usually use on the top of the star circle. The so-called stellar sphere is a means for our civilization to absorb the energy of the stars, which can almost tolerate the temperature of the stars. ”

Endure the temperature of the stars?! Liu Xuan was simply stunned, taking the sun as an example, the surface temperature is already as high as 6,000 degrees Celsius, not to mention the metal on the earth, I am afraid that the earth itself can be melted, the metal in the hands of this old man can actually withstand the temperature of their stars, it is simply quite powerful.

In the universe, the star of the sun is a fairly small star, and Liu Xuan, the star of this galaxy, has also seen that the energy on the surface is definitely several times higher than that of the sun.

"Do you understand how powerful this thing is?" The old man asked at Liu Xuan.

Liu Xuan nodded numbly, this thing is indeed quite powerful, and in the depths of Liu Xuan's eyes, he also wants to see what kind of element it is, whether it can be made on the earth, this thing is also very useful for them.

However, the old man did not mean to show this thing to Liu Xuan, after making sure that Liu Xuan knew the power of this thing, he directly reached out and threw this thing into the middle part of this room, and before Liu Xuan could ask the old man what he was doing here, he had already seen the inexplicable scene that surprised him.

The metal that was very powerful in the old man's mouth, the moment he arrived in the middle of this room, it was broken into many small pieces and fell to the ground, without any warning, without seeing any sparks, Liu Xuan didn't even see what happened, this metal had already become like this, Liu Xuan's mouth was so shocked that his mouth was wide open.

This completely subverted his idea, in his impression, cutting a metal, even if it is quite fragile, takes a certain amount of time, and even sparks are inevitable, but the scene he saw today made Liu Xuan completely change his mind, which is really a bit weird.

Defense facilities, Liu Xuan's mind finally appeared this word, it seems that the powerful defense facilities in this place are this invisible thing, this is still a metal, if their physical body is past, there is not much difference between it and this metal, a metal is cut, and I am afraid that a physical body will not be successful?

"This is the defense facility of this place, although it is invisible, but it is quite sharp, it can be said that there is nothing that cannot be cut, of course, this thing is generally used as a cutting machine by our civilization, and it is also quite good to use it as a defense facility, but unfortunately, we don't dare to make this thing too big, otherwise even if it is that = sixth level civilization, it will not attack

In. The old man looked at the pieces of metal scattered everywhere and said to Liu Xuan.

"What the hell is this, how can it be so sharp, I didn't see anything, I was directly separated!" Liu Xuan's tone trembled slightly.

This is not to blame Liu Xuan for such a gaffe, the means of high-tech civilization are simply unimaginable, fortunately, Liu Xuan also has the text of this place when he came to this place this time, otherwise he really doesn't know how he died when he suddenly encounters this thing, this is the power of high technology.

"Spatial cracks, this is the power of space, directly at the spatial level, this thing is completely decomposed and opened." The old man's introduction was very simple, but when he heard Liu Xuan's ears, there was only infinite shock, this is the power of space, indeed, it is really only the power of space that can be done to this extent.

Liu Xuan is already quite coveted for the technology of this space, the power of space is really quite powerful, the old man was not wrong just now, if this space crack is really made big enough, reaching the size of a galaxy, even the sixth level civilization will not dare to come in, although they also have this technology, but if they want to crack it, it is not so simple.

Liu Xuan himself also heard it, it's not that the old man's civilization doesn't want to do this, I'm afraid that even they themselves can't control such a big space crack, once they themselves can't control it, they will be trapped in the cage they built, and the power of space, they themselves can't get out.

Liu Xuan really hopes that this civilization can hand over this technology to them, once the earth civilization has mastered the power of space, it can definitely survive, and this technology itself is already a civilization that can make the earth civilization jump directly to the fifth level, this is the powerful power of space.

However, the old man also seemed to see Liu Xuan's thoughts. Then he said to Liu Xuan: "Don't think about it, even if our civilization is about to completely perish, we will not give you this kind of technology, let's not say whether you understand it or not, even if you can understand it, we will not hand it over to you." ”

"Why?" Liu Xuan didn't understand the old man's words, his own civilization was about to perish, why couldn't he give them such a key technology, this technology would just die with them in their hands, and it would not save their civilization from dire straits.

"I already said just now, technology must match morality, do you think your civilization and current moral level can afford the technology in this space?" The old man's face sank, and he asked Liu Xuan, this is the fundamental reason why they didn't give Liu Xuan's very critical technology to this civilization.

Liu Xuan was silent, he knew that they were really unworthy, according to their moral level, once they mastered the technology of this space, it was actually the same as the terrorists mastered nuclear technology, dangerous, quite dangerous, maybe it would also cause danger to other civilizations, their moral level

Can't afford such a technology.

"It's good to understand, in fact, there is another reason, if you bring this technology back, the sixth-level civilization will face you squarely, you can already reach the level of head-to-head with them, do you think that with the addition of space technology, you can compete with the sixth-level civilization?" The old man is still quite satisfied with Liu Xuan's performance, and he can correctly recognize himself, but it is not easy.

Liu Xuanpo shook his head a little sluggishly, this old man is right, just take this civilization as a lesson from the past, even if they master space technology, they can't beat the sixth level civilization.

"Don't think about it too much, this technology still needs you to discover and discover by yourself, but from the perspective of the universe, mastering space technology doesn't mean too many things, time is eternal, it is the most terrifying existence, but even us, the technology for time is just scratching the surface."

Liu Xuan continued to be silent, in the universe, there are many civilizations, and it is quite difficult to survive in the dark forest of the universe. Technology is one aspect, and morality may be another, but those are still a little far away from them, and it's a little early to think about it.

"Let me introduce you to these two technologies, the one on the left, don't look at it is just a very small black box, this is the special storage technology of our civilization, and the storage inside is the speed of light technology!" The old man pointed to the very inconspicuous thing on the left, and said something extremely surprising to Liu Xuan.

"Lightspeed Technology?!" Liu Xuan simply suspected that he had heard it wrong, the regret of losing the space technology in his heart just now simply disappeared in an instant, the speed of light technology, it turned out that they would use such a method to obtain this very critical technology, which is definitely of great significance to their civilization.

"Hehe, don't panic yet, although this technology is quite useful for you, but it will not protect your civilization, this technology on the right is what you need the most, the planet shield, the shield covering the surface of the planet, as long as there is enough energy, even a fifth-level civilization is difficult to break through your defenses, of course, you have also seen this thing, and the surface of this planet is covered with a layer of such things."

Liu Xuan's eyes were already shining, the old man was right, this technology was indeed what they needed very much, and the strength of the protective shield had been tried by themselves, and it was definitely quite powerful.

If they can really cover the earth with such a protective layer, their most fundamental planet is also protected, as long as they survive, there are infinite possibilities, in comparison, the second technology is more practical than the first technology, this is the technology that protects their survival.

"Of course, the second piece cannot be said to be a technology, it can only be said to be a finished product, after all, some technologies also involve space, and you can't find many materials, this finished product can be used directly, how to use it

I'll tell you later, and I can use it to protect your home planet. Before Liu Xuan was happy, the old man added again.

Liu Xuan was not too sad, after all, as long as they protected the earth, they could continue to survive, according to their own technology, they could already survive for a long time without the sun, and it was impossible to survive without the earth for the time being, so the earth itself was the most important, as long as the earth was not destroyed, their civilization would be immortal.

"Don't panic yet, I've already set it up, and the space crack will be gradually repaired in a while, and we can go over and have a look." The old man looked at Liu Xuan's longing look and said comfortingly.
