Mars.

I don't know how many meters deep underground.

Dr. Fan, who was standing in an empty "hall", had the word bewilderment written on his face at this moment.

Common sense told him that there could be no signal here, let alone human voices.

Therefore, when the phrase "Can you hear?" As the voice echoed in his ears, he even wondered if he was hallucinating due to dehydration.

Seeing that he didn't react, the staccato voice obviously carried a hint of hesitation, and muttered to himself.

"Strange...... Could it be that there is a problem with the translator? It stands to reason that it can't be. ”

…… Translator?

That's what it is.

Recovering from his bewilderment, Fan Tong looked around with a flashlight, looking for the source of the radio signal, and replied.

"Can you hear me...... Who are you? ”

The vicinity is full of hematite, and the signal penetration is very poor, considering the full signal grid, the signal source should be in this vicinity. However, the beam of the flashlight searched every corner of the hall, and Fan Tong did not see any shadow of electronic products.

"Don't look for it," looking at Fan Tong who was looking around, the voice in the communication channel suddenly took on a bit of playfulness, "If you can find me here, it will be really fun." ”

Gradually realizing that he was doing useless work, Fan Tong took a deep breath and gave up the useless search.

Reaching out and touching the transparent wall again, he nervously stepped back half a step back, repeating his earlier question in a wary tone.

"Who the hell are you? Is it ......?"

"Really?"

"Are you...... Martian? ”

Tremblingly, he said the words.

However, while Fan Tong was nervously waiting for the person's answer, there was suddenly no movement in the communication channel.

The silence lasted for about a minute.

Just as he began to wonder if he had guessed correctly, the strange alien soldiers were on their way to arrest him, and suddenly a string of piercing laughter came from the communication channel without warning.

"Hahaha! Interesting, it's been a long time since I've heard such a funny joke...... Unfortunately, you don't seem to be very smart. ”

Fan Tong: "......"

"If you mean the bugs that once lived on this planet, then I'm sorry, I'm not such a low-level existence," the laughter gradually subsided, and there was a hint of mockery in the tone of the voice, as well as a hint of regret, "I was pleasantly surprised to see the civilization composed of mammalian primate organic lifeforms, but I didn't expect it to be a primitive civilization that didn't even go out of the home planet." No wonder, you can't even find me anywhere. ”

Looking at Fan Tong, who was stepping back nervously, the voice smiled and continued.

"Don't be nervous...... I'm not going to eat you, so come, take off your mask and let me see what you look like." ”

"Are you crazy?" His eyes glared ahead, and Fan Tong subconsciously said, "There's not even air here." ”

If it weren't for the fact that this was an underground area where electromagnetic signals could not reach, he couldn't help but suspect that the people in the base had turned on the voice changer to play tricks on him.

He was sure that there must be a camera or something like that watching him around here, and maybe the guy hiding in the surveillance room was already laughing like crazy.

Who, exactly, and why......

He felt like his brain was messed up, like a crumpled tofu brain.

"Oh, yes, I almost forgot...... This planet has been destroyed by its former owner," as if reflecting on itself, and the voice muttered a sentence in embarrassment, "What to do?" The guys with the problem of their heads don't tell me how to tell them apart......"

Fan Tong: "What are you muttering?" ”

The owner of this planet?

Does it mean that there really was a civilization on this planet?

And the reason why Mars has become what it is now is not actually the reason that the academic community speculates at all, but the ancient civilization that once lived here?

It doesn't matter who he is anymore, and Fan Tong, an expert in planetary geology, is now curious about only one thing.

“…… What was Mars like before? ”

"What was it like before? Even if I describe it to you, most of you will not understand it with your level of civilization, after all, you have only seen your home planet. In short, it is an enviable world with a mild atmosphere, a highly self-healing ecosystem in the nitrogen-oxygen atmosphere, and a series of factors such as environment, temperature, and humidity at different latitudes all meet the survival needs of known higher organic life. You can think of it as a place where the ecosystem is exceptionally rich and 120% habitable for all the organic life of all the genera, genera, and species. ”

Habitable for all high-level creatures?

Fan Tong doesn't particularly understand what the concept of 120% corresponds to, but if you listen to this description alone, it should be a better place than the earth.

After all, at the rate of extinction of species on Earth, it is hard to imagine that it is 120% habitable for all living organisms. And if this trend continues, it won't be needed for a thousand years, and human beings themselves will not be able to stand it......

"Yes, I had a brilliant idea." Suddenly something came to mind, and the voice in the communication channel carried a hint of excitement, "Tell me first, how far your civilization has developed." ”

The moment he heard this, the expression on Fan Tong's face gradually became vigilant.

As if noticing his mood swings, the voice smiled.

"Don't be nervous, don't say we're not in the same universe, even if we are, we're not interested in a group of monkeys living on continental planets, especially when these monkeys are so ugly."

“…… Not in a universe? Thinking of some of the interpretations of Academician Lu's papers that he had read on the Internet before, as well as the concept of extra dimensions, Fan Tong frowned and said, "Can you still come from the Void?" ”

"Oh? Are all the current low-level civilizations so good? There was a clear hint of interest in the voice, "Looks like those guys' oracles are still working...... If it weren't for the translator's problem. ”

There are more and more unintelligible concepts.

Now even the oracles have popped up.

Looking at the empty hall, Fan Tong clenched the multi-functional shovel in his hand and continued quietly.

"I can't trust a person who doesn't even want to show his face and hides his head when he speaks, and I won't answer any of your questions about 'us' until you explain who you are and what you want to do."

"Then we'll each answer the other," the voice replied dryly, in a nonchalant tone, "if you feel that my question offends you, or violates your poor privacy, you may choose to refuse to answer." As a courtesy, I can allow you to ask questions first. ”

"Deal."

Although I still have doubts in my heart, I am still satisfied with this sincerity.

Fan Tong organized the words in his mind and continued to speak.

"So my question...... Who are you? ”

"Who am I? It's a bit of an abstract question, and I'm sure you don't intend to ask me for a philosophical answer, but my name means nothing to you. In that case, let's use what you call a 'Martian'. While they were still around, they called me a 'holy relic.' ”

"Relic?"

"Well, in their culture, presumably resembling a special life form that exists far above them. They are indeed right, and I am indeed much more advanced than them. Okay, that's all I have to say, and while I don't mind talking to you more, it's a matter of sincerity. ”

Fan Tong tried to argue: "But you didn't explain anything clearly. ”

"That's because the question you're asking is confusing on its own," the voice continued unceremoniously, "if you don't want to waste any more time, answer my question and then our conversation can continue." ”

“…… You ask. ”

"Is there a text message function on your communication module? It's not a complicated question, but you may not remember it in your brain. ”

“……”

Resisting the urge to get angry, Fan Tong silently reached out and clicked twice on the computer on his wrist, and quickly switched the communication channel to the text input interface.

I don't know why this guy is so familiar with the communication technology and language he uses, but it's a good thing.

After both sides showed enough sincerity, he naturally had the opportunity to ask the reason.

Soon, a text message arrived.

However, the moment he opened the text message, the whole person was stunned as if he was stupid.

[For any ε>0, there are only a finite number of triples (a, b, c), satisfying that a, b, and c are coprime positive integers, and a+b=c, and c>rad(abc)^(1+ε). 】

Fan Tong: "??? ”

This is......

Math problems?

What the heck?!

He had expected this guy to ask questions like "how many planets do you control", "how many starships do you have", or at least "how many people?" he had even figured out how to answer.

However, he didn't think that in the end, it was actually a math problem that was thrown over.

Frowning, Fan Tong stared at the question carefully.

Although most of his math knowledge was returned to his teacher in the year of graduation, he was barely able to understand the topic.

I just don't know why......

It seemed like a simple topic, but he didn't have the slightest clue.

Seeing that Fan Tong didn't react for a long time, the voice gradually brought some disappointment.

"It seems that you are not the chosen one."

“…… The Chosen One? ”

"Generally speaking, the smartest one in your civilization, or at least the one that distinguishes him from his kind. It's like facing the same stone monument, some baboons will only pee on it, but some baboons can learn the true meaning of civilization from it, so as to lead their tribe out of ignorance and towards enlightenment...... I don't know if you can understand me when I say this, after all, your understanding of intelligent beings is probably still stuck in yourself. ”

There was a palpable hint of banter in the voice.

Although he was dissatisfied with the quantifier "only", Fan Tong was powerless to refute it at all.

It was as if he couldn't understand what the invisible "wall" in front of him was, where that mysterious voice came from, and how he knew everything about the language he used......

Perhaps the person he was talking to really came from a civilization that was unimaginably powerful.

And at this moment, standing in front of him is really no different from a primitive person.

A soft sigh came from the communication channel.

"Let's go back."

"Take my questions back with you."

"Find one of your fellow citizens who can unravel it, and let him come here to me with the answer."

"If you still want to do something good for your fellow citizens."
