“…… There is no intelligent life. ”

Lu Yuanming's second exploration cannot be said to be a failure, but it is very different from the expected success.

He did find traces of civilization through the hollow passages.

It is a flat circular cavity with a height of about 10 meters, but the length and width are at least 50,000 meters, and from the calculations of scientists, this is an artificial cavity, which reduces its height and applies space to the width and length, and the area that can be left in the circle is the largest, which is a flat circular cavity.

The void is filled with multi-storey buildings connected to the top, which are either residential buildings or functional buildings, such as plantations.

It is a bryophyte crop that, judging by its color, does not rely on sunlight for photosynthesis, but instead provides a source of energy for its growth by a sparkling shimmering powder buried underneath it.

It's a specialty of this small world.

A high-energy spar, widely distributed in this small world, with a large number of veins, the total amount of which is no less than one million tons in the area detected so far.

This kind of energy spar has been brought out of the material universe by Lu Yuanming, the first time he brought it out, all these spars were shattered and disappeared, and the second time he used cognitive blessings to bring them out, which made these spars exist in the material world.

Through scientific research, this crystal is a kind of substance that will never exist in the material universe, because its internal microstructure presents a chaotic state, changing all the time, but when it comes to the macroscopic material level, it presents a stable state, and in this chaotic structure, there is an energy flow, which is presented in a fluid state under the wonderful constraints of the chaotic state.

Scientists can use a variety of methods to excite the energy in this energy crystal, such as putting it in water, depending on the amount of water and the number of energy crystals, the water can be kept at a certain temperature at room temperature, and even let it be heated to a boiling state of 100 degrees for a long time.

When an electric current passes through the energy crystal, the energy crystal will emit an electric current, that is, it is no longer heat energy that comes out of the energy crystal, but an electric current.

If you hit the energy crystal with high-energy particles, the same high-energy particles will appear, but in more quantities, and this can actually be turned into lasers or energy pulses.

At the same time, if the energy in this energy spar is exhausted, the spar itself remains stable, as long as it is placed in a high-energy environment, such as a reactor, then it will be charged itself, just like the high-energy state falls to the low-energy state, it will gradually refill with energy.

And its energy storage efficiency is more than five times higher than the space matrix battery of the current fourth-level cosmic civilization of mankind!!

The key is that it is stable and does not need to consume energy to maintain a high curvature state like a space matrix battery, as long as it is not excited, then it can be stored at room temperature for a long time!

It's a universal energy storage material!

Scientists have even simulated the creation of this energy hedron for energy loops, for energy hubs, for defensive platforms, and for increasing the power of energy beam weapons...... Each of these features can increase the efficiency of existing appliances by at least 30 percent, making them more energy-efficient, more efficient, more powerful, and more durable in terms of energy output......

At least 30% increase!

Even in some fields, this kind of energy spar will directly produce qualitative changes!

For example, for the problem of excess energy storage in energy buildings such as Dyson spheres!

Although it is not enough for human civilization to leapfrog to the fifth level all at once, the existence of this energy crystal alone is enough to make human beings become some kind of special case among the fourth-level cosmic civilizations.

Similar to the fantasy world, the title in the same class is added with a unique title, for example, everyone is a Dou Emperor, but the protagonist is called the Eternal Dou Emperor, this look knows that it means to fight ten hundred of the same class.

Humans have obtained this kind of spar, and perhaps add the alchemy of metal property transformation, and human beings have begun to have this taste in the fourth-level cosmic civilization.

In view of the fact that this energy spar is so important and precious, even Lu Yuanming can't help it, and this kind of energy spar is not only stored in this small world in huge quantities, but also extremely convenient to mine, almost all of them exist in the form of ore veins, and at the same time, if human beings want to transform the existing energy system, defense system, combat system, and civil system with this energy spar, the total amount required is at least more than two million tons, and this is not counting the loss of time.

Although this energy spar is stable, its material essence is not tough, so it will cause natural wear and tear in daily use, even if the loss is slight, far inferior to metal, but this cannot be reused, so this energy spar is a non-renewable extremely precious resource.

According to the idea of the human government, the entire small world must be hollowed out, and the slightest energy spar in it must not be spared, but there is no doubt that this approach is to completely ignore the life and death of intelligent life in the small world...... If there is still intelligent life.

Therefore, Lu Yuanming forcibly restrained the idea of directly excavating and absorbing the materials of this small world, and still insisted on continuing to investigate the small world.

The anti-positive energy spar vein is there, and it is impossible to run away on long legs, even if the human government and military, and even scientists have the idea of being in the bag, but Lu Yuanming still resists public opinion and continues to carry out exploration actions.

In this way, it was still Lu Yuanming who entered alone, and then took more than 9,800 underground special detectors to scan and explore the entire small world.

Such days are actually quite boring, but from time to time you can find the remains of a hollow civilization, which is full of people, but there are words, some stone tablets that resemble books, and agricultural ...... The strangest thing is that even the plants are still growing, but there is not a single intelligent life inside.

There are even half-eaten foods in some of the hollows.

It's just weird.

That's it, Lu Yuanming entered the small world with more than 2,000 probes every day, explored for three weeks in a row, and finally explored the edge of this small world, which is a layer of invisible and qualitative shell, extremely tough, but there is nothing outside, the whole small world is a sphere with a diameter of more than 60,000 kilometers, about a little more than five times the diameter of the earth, but it is all rocks and soil, as well as various mineral veins, filled to the brim, and the void may not even have one ten-thousandth of the space.

"After exploring, there are more than 140 cavities, each of which has the remains of civilization, of which more than two-thirds of the cavities exist independently, and the rest of the cavities are connected to each other by passages."

"From the traces of civilization that have been discovered, it shows that, except for a few empty holes, the civilization of this small world has the civilization of the Iron Age, with branches of the civilization tree such as writing, mathematics, images, sculptures, currency, etc., and has not found any extraordinary signs of the civilization of the small world for the time being, and at the same time, it is impossible to find the whereabouts of the intelligent life in this small world."

"From the areas that have been detected so far, no traces of large life have been found, and no areas that may be dangerous, in summary, we suggest that this small world can be fully developed, although there is a certain possibility of danger, but compared to the value of it, this danger is still within the tolerable range."

Lu Yuanming listened to the staff and think tank teams in the video conference, as well as the development calls of scientists and even politicians, but he was still silent and did not say a word.

This situation quickly attracted the attention of others, but they didn't understand what Lu Yuanming was still hesitating.

The value of this energy spar is probably not inferior to the metallic nature transformation alchemy, and even in terms of universality, its value may be much higher than that of the metallic nature transformation alchemy.

Moreover, this small world is a truly solid all-material small world, and the sum of matter in it is at least dozens of times more than that of the previous small world!

Therefore, for any reason, it is impossible for human beings to let go of this small world.

Now that it has been explored clearly, there is no longer any intellectual creature in it, so what is Lu Yuanming hesitating?

Lu Yuanming obviously knew that he had to give an explanation at this time, although it didn't hurt even if he didn't give an explanation, but this was the bottom line he set for himself after making the decision, so he said: "I'm sorry, everyone, I don't know what I'm hesitating about, but every time I enter that small world, I have a premonition of danger, a very strange premonition of danger, which is different from the premonition of danger in the past, there is a danger that can't hurt me at all, but an inexplicable feeling makes me very uncomfortable...... In short, I still think that this small world should not be developed on a large scale, there is some danger in it. ”

Everyone was stunned, and then they were all talking, and then a scholar asked bluntly: "Your Excellency, your decision is necessary, but can we ask?" How long will this non-development last? You can't give up this small world, right? ”

“…… Won't give up. Lu Yuanming sighed and said: "This kind of treasure is absolutely impossible to give up, we have to get it no matter what, but please give me some more time, I will bring more than eight hundred probes to search for the danger in it......"

Having said that, no one ever mentioned developing a small world right away.

Because all the people who can appear at this meeting, they all know a truth, that is, human civilization, including the current human group, actually has no way to restrict and impeach Lu Yuanming, which is no longer a broken nerve, it is directly a suicide of pulling out the spine, piercing the heart, and breaking the brain.

Now the only thing that can limit Lu Yuanming is actually his own morality and the centripetal force of civilization.

When Lu Yuanming explained, and also gave a general time limit, and at the same time, there was actually some pleading, no one would force Lu Yuanming at this time, because this is really ignorant of lifting.

In the next time, Lu Yuanming continued to explore this small world in depth, but with his own strength, he was really powerless to explore such a huge space, and he couldn't always open his high-dimensional vision to explore, right?

In this way, the time dragged on for more than a month, although no one urged it, after all, in terms of the current lifespan of human beings over 10,000 years, a month is equivalent to less than a day before.

But Lu Yuanming still felt the pressure.

It is impossible to give up this small world, not to mention the abundant substances in it, it is impossible to give up just the existence of the energy crystal.

But......

"I still stand by my opinion, there is danger in this small world, although I don't know what it is...... Therefore, this small world can be developed, but there must be two prerequisites: first, no more than 10 people can enter at a time...... No, 10,000, at the same time, you must report to me every hour the location, and whether it is safe, second, I ask the Academy of Sciences and the Ministry of Engineering to immediately activate the emergency plan, I don't care if you forget to sleep and eat, or just roll up the bed nest for me to lie in the research institute or factory, or make me an efficient material handling and suction instrument, I will be stationed on both sides of the space crack in this small world, energy spars we will all obtain, but speed speed speed, efficiency efficiency efficiency, I want to be able to clean up this little world as quickly as possible, and then we'll be out and about again! ”

This is Lu Yuanming's final decision.

And this decision made everyone very excited.

This is not a small number of people, now all mankind and aliens also know that this small world has a unique energy crystal, the acquisition of this new material means that a small industrial revolution is about to break out, which is not only the safety of the human group will be greatly improved, but also means that everyone will live more comfortably, life safety, wealth accumulation, and more and better jobs.

It can be said that this is a carnival for the whole people.

In this way, Lu Yuanming began to supervise all the dangers of the small world, and every time nine thousand human workers entered, the work of absorbing matter was extremely fast.

In fact, the task of these human workers is to excavate energy crystals, and this new material related to the future of human civilization is naturally handed over to living people to collect, even a small amount of energy crystals cannot be let go, and every time a vein is collected, it will be sent to the entrance of the space crack, waiting for Lu Yuanming to use cognitive stabilization to send it to the material universe.

In this way, because of the energy spar veins, the speed of absorbing matter was much lower than that of the alchemy small world, and after more than three months, all the materials of the energy spar small world were absorbed.

In order to be able to store these materials, the industrial capacity of human beings has been fully utilized, a large number of carrier-storage ships have been manufactured, various minerals have been smelted, and the remaining materials cannot be directly discarded, and stored as energy sources and particle recombination materials.

Three months later, everything in this small world was hollowed out, and Lu Yuanming withdrew from the small world of energy crystals with more than a thousand workers who entered each time.

A billion human beings were still carnival, and the initial use of energy crystals had already begun to be implemented in the past three months, but Lu Yuanming's face was full of seriousness and even anxiety.

He didn't know where his anxiety came from, he didn't even know what the danger of this small world was, because the small world had been hollowed out and had begun to annihilate itself, and he didn't want anything else now, he just wanted to get out of this small world as soon as possible, this place that made him feel weird.

Finally, under Lu Yuanming's strong decision, the human group did not delay in this small world, but activated the gravitational slingshot at the fastest speed, aiming for an area 10,000 light-years away, towards the third coordinate.

By the time the human group broke away from the gravitational slingshot, it had been more than a year later, and it was not until this moment that Lu Yuanming finally breathed a sigh of relief, and the strong sense of danger that was omnipresent had finally disappeared, and that weird feeling had finally disappeared.

Faced with Lu Yuanming's relieved state, the rest of the people were all inexplicable.

When the energy spar small world was developed before, Tang Zhe'an, Wei, and Ez actually proposed to go in and help, but they were rejected by Lu Yuanming in an extremely resolute tone.

So Wei asked, "What the hell is going on?" Why are you so nervous? ”

Lu Yuanming hesitated for a moment and said, "I don't know, but I just want to stay away from that small world." ”

Wei continued to ask strangely: "But when the development of that small world was completed, we didn't encounter any strange things, everyone returned safely, and all the billion humans were ...... What the hell are you nervous about? ”

Lu Yuanming said irritably: "I don't know, I really don't know...... I just feel like I'm going to go crazy if I keep staying there......"

"A strange feeling that I can't understand, that I can't understand, that makes me go crazy there, and then fall into a demon and turn into something horrible......"
