Suitable temperature is the basis for the birth of all intelligent organisms. Of course, the vastness of the universe cannot rule out intelligent organisms that can survive in harsh environments. However, organisms that are more environmentally adaptable and survive in this special environment often Unable to adapt to common environmental factors, they are more likely to die young.
The existence of cracks in the earth means that there are drastic changes in the geographical environment of this planet. The geothermal overflow effect makes the temperature around the cracks in the earth or in the underground internal space create a living space suitable for the birth of life.
Everyone nervously looked at the large command screen. A large number of unmanned reconnaissance ships focused on the cracks in the earth. They gathered around and deployed reconnaissance aircraft and exploration robots... to conduct an all-round exploration of the interior of the cracks in the earth.
Soon, alien plants of different colors appeared at both ends of the underground cracks, taking root tenaciously on the steep mountain wall.
"Oh God! There are actually plants, and there is really intelligent civilization here!" Professor Smith stared at the command screen with his eyes wide open, exclaiming excitedly.
"Not necessarily, not necessarily yet! Although the climate has moderated and is suitable for life to survive, the underground world environment has natural limitations and may not be able to develop intelligent civilization." Professor Yang Yi's voice trembled and he shook his head excitedly. , cannot believe in the existence of intelligent civilization.
There is a huge development difference between the surface world and the underground world. They also encountered underground civilization on Blue Pole Star before. Due to the limited space of the underground world, that underground civilization has experienced tens of thousands of years of development and still cannot develop advanced civilization. , let alone the planet in front of us with a more severe climate and environment, it is really hard to imagine what kind of underground intelligent civilization can be developed in the limited underground space? Professor Yang Yi's conservative judgment was immediately recognized by most people.
"No, I just feel that the underground world is definitely not simple. Look at the length of this crack in the earth. It may be artificially created. Isn't the purpose just to expand the space of the underground world!" Professor Smith shook his head firmly and denied.
Hearing this, everyone frowned. What Smith said in the classroom was not unreasonable. The length of this crack in the earth is too long. This special geological environment cannot be easily created by the natural environment.
"Look, this set of isotope detection data shows that the age of this planet is estimated to be about 3.87 billion years. It is a relatively stable planet. The underground activities should be stable in the area. So, how did such a long crack in the earth come about? Where was it born? Why won't it be healed by squeezing?" Professor Smith pointed at a set of data on the command screen and reminded everyone while looking at them.
Everyone looked at the data set pointed by Professor Smith.
Detecting the age of the planet is measured using the decay cycle of elements, specifically by measuring the content of the element C12 in the material. Since radioactive elements release energy, this energy release is equivalent to the change in the mass of the material, E=MC^2, The element C12 continues to release energy, so the content of C12 becomes less and less.
When the content of this element is half of its original value, the time it takes is called half-life. Since different elements have different half-lives, other elements with longer decay cycles can also be measured.
The data that Professor Smith is referring to is the data detected by the Planetary Mechanical Corps’ further analysis of the zircon (ZrSiO4) element. Zircon (ZrSiO4) is a natural ore. The uranium-lead dating method requires the use of zircon, because uranium Atoms are similar to zirconium atoms and can be drilled into the zirconium lattice to replace the original zirconium atoms. However, unstable uranium atoms will eventually decay into lead atoms and be sealed in zircon. The lattice of zirconium atoms only allows Special atoms that meet the charge requirements enter, so the lead element itself cannot enter the zirconium atomic lattice. This unidirectionality provides accurate technical support for determining the formation of planetary geology.
The old planet that has experienced 3.8 billion years of precipitation, its trajectory, geological changes... have become stable, just like the Earth, the home planet of human beings, which is 4.5 billion years old and has an extremely stable star system with "stability" Otherwise, human civilization would not be able to survive such years stably on a planet.
…
Everyone looked at each other and were shocked by Professor Smith's analysis. There is most likely a civilization with highly advanced technology in the underground space of this planet. Otherwise, how could they develop such a long crack in the earth.
"No, if this civilization can really develop this kind of technology, how come they still stay in the underground world and don't develop towards the surface or into space? I'm afraid there are other unknown factors that caused this crack in the earth." Yang Yi The professor frowned and retorted insistently.
Professor Smith shook his head solemnly and retorted: "No, they don't want to develop on the ground and in space. There must be other factors. Maybe they have adapted to the underground environment. It is not urgent to develop on the ground and in space. Besides, how to explain the incident of the alien energy attack? It’s too much of a coincidence!”
"I..." Professor Yang Yi frowned, just about to refute Professor Smith's speculation from other points of view.
At this time, Zhou Yu looked deeply at the command screen and stopped him: "Don't rush to conclusions yet, everyone pays attention! The reconnaissance corps will reveal the answer to the mystery for us."
After hearing this, everyone fell silent and stared at the large command screen.
The surveillance screen showed the vision of countless reconnaissance robots exploring underground cracks.
The unmanned reconnaissance aircraft flew straight into the bottom of the crack, 2,000 meters, 2,200 meters... As if traveling through an endless black hole, the unmanned reconnaissance aircraft could not reach the end of the underground crack for a long time.
"The cracks ahead are shrinking!"
"Be careful of complex terrain, there are raised rock formations!"
"No, there is signal interference. The signal of UAV 176 was suddenly interrupted and control was lost!"
"Send additional signal balls immediately for signal relay transmission."
…
In the flagship command room, the console technicians were busy and busy, and various abnormal situations kept emerging. With Zhou Xiaozhi's assistance, the panicked and unhurried remote-controlled reconnaissance corps continued to penetrate deep into the cracks in the earth.
Time flies, and the fissures in the earth are deeper than everyone imagined. The unmanned reconnaissance fleet has penetrated five or six kilometers. Except for the increasingly empty underground environment and the spectacular and beautiful magical adventures in the underground world, no intelligent civilization has been discovered at all. "architecture".
It’s hard to understand. All speculations are false
How deep is this crack in the earth? When will the drone reconnaissance fleet reach the bottom? Everyone's expressions gradually became impatient.
At this moment, the holographic screen suddenly "boom, boom..." producing a large explosion of fire, and the smart screen monitored the images one by one, falling into darkness one by one.
"No, reconnaissance aircraft group No. 17 hit an unknown substance and crashed collectively."
"Reconnaissance aircraft group No. 11 also hit an unknown substance and lost contact."
"Four reconnaissance aircraft group No. 27 was damaged, and a material similar to an energy defense cover was found."
…
The monitor on the operating platform panicked and continuously reported the damage to the reconnaissance fleet.
Everyone was shocked by the sudden change in launch, and their eyes were fixed on the command screen, waiting for the result to happen.
Soon, a scene that shocked everyone appeared. Through the explosion of the reconnaissance aircraft group, a layer of light blue energy shield could be seen appearing in the underground cracks. After the unmanned reconnaissance aircraft group hit this energy shield, all of them Qi crashed.
Everyone gasped in unison.
"Really, there is an underground intelligent civilization!"
"Yeah! I didn't expect this planet..."
"Are they the ones attacking us? Since they have developed energy shields, why haven't they developed space power?"
"This defensive shield is a magnetic shield. It has a certain technical level, but it seems that the level of technology is not high!"
"Wrong, big mistake. You have to consider the length and range of this magnetic shield. I'm afraid they have reached the cutting edge of this magnetic shield technology."
…
There was a "boom" in the flagship command room, and chaos suddenly broke out. After the experts and professors saw the defensive shield, the truth became clear. Everyone began to analyze the strength of this underground civilization based on the strength of the defensive shield.
The magnetic shield was like an indestructible giant shield, blocking the unmanned reconnaissance fleet from continuing to explore the cracks.
What should we do now
Everyone looked at Zhou Yu, expecting his order.
Zhou Yu lived up to expectations. Looking at Zhou Xiaozhi, he decisively ordered: "Send a broadcast to the other party and ask them why they attacked us?"
After listening to Zhou Yu's order, Professor Smith's expression changed drastically, and he quickly stopped him: "Xiaozhi, wait a moment!"
"Commander, the opponent's combat strength has not yet been determined. The tone of the broadcast may easily cause disputes. It is better to say hello in a friendly way!" Professor Smith looked at Zhou Yu and said urgently.
"Yes! We don't know the details of this civilization at all. Besides, our current combat power is limited, so it's better to be safe!" Yang Yijiao nodded repeatedly, agreed with Professor Smith's words, and advised Zhou Yu.
The others looked at Zhou Yu and wanted to speak.
Zhou Yu stretched out his hand and ignored everyone's reaction. He looked at Zhou Xiaozhi and ordered decisively: "Xiaozhi, execute the order immediately and speak tougher."
"Follow your orders, Commander!" Zhou Xiaozhi's face tightened and he acted as ordered.
Immediately, the broadcast compiled by Zhou Xiaozhi was transmitted directly to the unknown civilization under the cracks in the earth through the tunnel communicator.
Zhou Yu patiently waited for the other party's reply, his deep eyes fell on the holographic screen, and he was thinking about something seriously. However, it was obvious that what he was thinking about was not the problem that Professor Smith and the others were worried about, but the comprehensive command of all the monitoring data on the large screen. , searching for clues of information from effective information.
They both belong to the underground civilization, but the civilization in front of them is undoubtedly many times more powerful. They have mastered powerful magnetic shield technology. At the same time, they also have ultra-long-range interstellar weapons that can cause fatal damage to their warships.
Especially those kinds of alien energy weapons. If an ordinary mechanical civilization encountered this strike force, the fleet would have been wiped out long ago. Therefore, judging from these two e-commerce companies, this intelligent civilization already has the strength to go to the outer sky, or they have already A proper starship was developed, but it was just hidden in a corner.
…
Various thoughts appeared in Zhou Yu's mind one after another.
The holographic screen in front of Zhou Yu suddenly lit up and a large piece of unfamiliar text appeared in a strange shape.
Zhou Xiaozhihui reported: "Commander, we have obtained the other party's text message. However, the other party did not convey the auxiliary interpretation information. It will take about 3 days to decipher it. The decipherment rate is about 47%."
Hearing this, Zhou Yu's expression tightened and he asked one after another: "What communication method does the other party use? How come they can interpret our information so quickly? Are their computers more powerful than yours?"
"Commander, this message was not sent through radio, nor through quantum entanglement's long-distance communication technology, but using a method similar to space broadcasting. The transmission speed only took 0.3 seconds." Zhou Xiaozhi took the lead in answering Zhou Yu The first question.
After a pause, Zhou Xiaozhi continued to introduce: "Commander, the information I conveyed uses scientific keys and is marked with a translation structure, so the other party can easily translate our message into their own language and understand it, and it will not take more than In 20 seconds, the computing power they have is about three times higher than mine, but Xiaozhi is better than their computer in other aspects."
Science Key is a decoding tool that uses some common basic principles of cosmic physics, mathematics, chemistry... and other subjects to compile. Its greatest use is that when there are communication barriers between the two civilizations, Science Key can be used to decode and translate. .
As long as an intelligent civilization has a little research in the field of scientific research, it can use this scientific key to easily interpret the other party's information and the meaning attached to the information.
"It's unreasonable to ask the other party for decoding tools or scientific key structures provided by them. Otherwise, we will not have any communication with them." Zhou Yu ordered with a dark face as he looked at Zhou Xiaozhi.
"Okay, Commander!" Zhou Xiaozhi readily agreed.
Everyone looked at each other and felt helpless at Zhou Yu's tough attitude. The true details of this civilization have not yet been exposed. After data comparison, it is clear that the technological level of this unknown civilization is decades higher than human civilization.
However, Zhou Yu didn't know if he had taken the wrong medicine. He was not polite to this enemy who was more powerful than himself. He scolded him when he changed his name and approved the criticism when it was necessary. He also showed a strong self-confidence.
"Commander, I received the message from the other party. The other party sent the scientific key they compiled. The information has been successfully compiled." Zhou Xiaozhi looked at Zhou Yu and reported.
"What information is it? Get the information quickly!" Zhou Yu refreshed and ordered Zhou Xiaozhi.
"Okay, Commander!" Zhou Xiaozhi responded.
Immediately, the screen on the command screen changed, showing a paragraph in mixed Chinese and English.
