Mars.

I don't know how many meters deep underground.

Standing in an empty "Hall", Dr. Fan's face is now full of two words of stupidity.

Common sense tells him that there is no signal here, let alone the voice of people.

So when that "can you hear me?" When his voice reverberated in his ear, he even doubted whether he had hallucinations due to dehydration.

Seeing that he didn't respond at all, the intermittent voice obviously took a trace of hesitation and murmured to himself.

"Strange Is there something wrong with the translator? It's not possible. "

…… translator?

What is that.

Fan Tong looked around with a flashlight, looking for the source of the radio signal, and said back.

"I can hear Who are you? "

There are hematite nearby, and the signal penetration is very poor. Considering that the signal is full, the signal source should be nearby. However, the light 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," said fan Tong, looking around at the voice on the communication channel, with a tone of ponder. "If you can find me here, it's really fun."

Gradually realizing that he was doing no work, fan Tong took a deep breath and gave up looking for useless places.

Reaching out and touching the transparent wall again, he stepped back nervously and repeated his previous questions in an alert tone.

"Who are you? Don't you... "

"Isn't it?"

"Are you Martian? "

Trembling, he uttered the sentence.

However, while fan Tong was waiting for the man's answer nervously, there was no movement in the communication channel.

The silence lasted about a minute.

As he began to doubt whether he was right or not, the strange alien soldiers were on their way to catch him. Suddenly, a series of sharp laughter came from the communication channel without warning.

"Hahahaha! Interesting. I haven't heard such an interesting joke for a long time But it's a pity you don't look very smart. "

Fan Tong: "..."

"If you mean Martian, I mean those bedbugs who once lived on this planet, I'm sorry, but I'm not so low." laughter gradually converged, and there was a hint of irony and a hint of regret in the voice. "I was surprised to see the civilization composed of mammalian primate organism, but I didn't expect that It's a primitive civilization that didn't even go out. No wonder you can't even find out where I am. "

Looking at fan Tong, who retreated nervously, the voice smiled and continued.

"Don't be nervous I won't eat you again. Come on, take off the mask and let me see what you look like. "

"Are you crazy?" His eyes glared at the front, fan Tong said subconsciously, "there is no air here."

If it wasn't for the underground where the electromagnetic signal couldn't reach, he couldn't help but suspect that the people in the base had turned on the sound transformer to play tricks on themselves.

Now he's determined that there must be a camera or something like that watching him around here, and maybe the man hiding in the monitoring room is laughing crazy.

As for who it is and why it is done

He felt his brain was in a mess, just like the bean curd brain being crumpled.

"Oh, yes, I almost forgot The planet has been destroyed by its former owner, "it seems to be a self reflection. After a murmur, it is in a dilemma." what should I do? Those with brain problems don't tell me how to distinguish them... "

Fan Tong: "what are you muttering about?"

The owner of the planet?

Is there any civilization on this planet?

What's more, the reason why Mars has become what it is now is not the reason that the academia guessed, but the ancient civilization that once lived here did it?

It's not so important who he is. Fan Tong, an expert in planetary geology, is only curious about one thing.

“…… What was Mars like before? "

"What was it like before? Even if I have described it to you, you probably can't understand it at your civilization level. After all, you have only seen your own mother star. In a word, it is a mild to enviable world. There is an ecosystem with strong self-healing ability in the nitrogen and oxygen atmosphere. A series of factors such as environment, temperature, humidity and so on in different latitudes all meet the survival needs of known advanced organic organisms. You can think of it as an ecosystem that is extremely rich, and it's good for 120% of the organic organisms of all the families and species of the phylum. "Livable for all advanced creatures?

Fan Tong doesn't particularly understand the concept of 120%, but listening to this description alone should be a better place than the earth.

After all, at the rate of extinction on earth, it's hard to imagine 120% livable for all living things. And according to this trend, it's not necessary for a thousand years. Human beings can't stand it

"Yes, I have a wonderful idea." Suddenly thought of what, the voice in the communication channel with a trace of excitement, "you first tell me, your civilization probably developed to what extent."

At the moment of hearing this sentence, the expression on fan Tong's face gradually became alert.

It seemed that he noticed the fluctuation of his mood, and the voice said with a smile.

"Don't worry, 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 the mainland planet, especially these monkeys are so ugly."

“…… Not in one universe? " Thinking about the interpretation of academician Lu's papers and the concept of extra dimension that he had seen on the Internet before, fan Tong frowned and said, "can you still come from the void?"

"Oh? Are the lower civilizations so good now? " There was a hint of interest in the voice. "It seems that the oracle of those guys has played a role If it wasn't for the translator. "

There are more and more concepts that you can't understand.

Now even the Oracle appears.

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

"I can't believe that a person who doesn't even want to show his face or talk with his head or horns will not answer any questions about us until you state your identity and intention."

"Let's answer each other one by one," said the voice in a tone of indifference. "If you think my question offends you or your poor privacy, you can choose to refuse to answer. As a matter of courtesy, I can allow you to ask questions first. "

"Close."

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

Fan Tongtong organized a language in his mind and continued to speak.

"Then my question Who are you? "

"Who am I? This question is a little abstract. I believe you are not going to seek philosophical answers from me, but my name means nothing to you. In that case, use what you call "Martian". While they were still there, they called me a "relic."

"Relics?"

"Well, in their culture, it's probably similar to a special form of life that exists far above them. Their understanding is really right. I am much higher than them. Well, I'll say so much. Although I don't mind talking to you more, it involves sincerity. "

Fan Tong tried to argue, "but you didn't explain anything at all."

"That's because the questions you ask are confusing," the voice went on without saying politely. "If you don't want to waste any more time, answer my questions, and then our conversation can go on."

“…… You ask. "

"Does your communication module receive text messages? Although the problem is not very complicated, it may not be remembered with your brain capacity. "

“……”

Restraining the impulse to get angry, fan Tong silently reached out and clicked twice on the wrist computer, and soon turned the communication channel to the text input interface.

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

When both sides show enough sincerity, he will have a chance to ask why.

Soon, a line of text messages was sent.

However, in the moment when he opened the text message, the whole person seemed to be stupefied.

[for any ε > 0, there are only a finite number of triples (a, B, c), which satisfy that a, B, C are positive integers of reciprocal prime, and a + B = C, which has C > rad (ABC) ^ (1 + ε). ]"??"

This is

Math questions?

What the hell?!

He thought this guy would ask questions like "how many planets do you control", "how many starships do you own", or at least "how many people do you have", and he even figured out how to answer them.

However, he didn't think about it. At last, he was thrown a math problem.

Frowning, fan Tong stared at the subject carefully.

Although most of his mathematics knowledge was returned to his teacher in the year of graduation, the subject was barely understandable.

Just don't know whyHe has no clue about a seemingly simple subject.

Seeing fan Tong's unresponsiveness for a long time, the voice gradually brought some disappointment.

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

“…… Who was chosen? "

"Generally speaking, it's the smartest one in your civilization, or at least it's different from other cultures. It's like facing the same stone tablet, some baboons can only pee at it, but some baboons can understand the essence of civilization from it, so as to lead his tribe to get rid of ignorance and go to enlightenment I don't know if you can understand that. After all, your understanding of intelligent creatures probably remains in yourself. "

There was an obvious banter in the voice.

Although he was dissatisfied with the Quantifier "only", fan Tong could not refute it at all.

It's like he can't understand what the invisible "wall" in front of him is, where the mysterious voice comes from, and how he knows the language he uses

Maybe the person who is talking with him really comes from a civilization that is so powerful that he can't imagine.

At this moment, I stand in front of him just like the primitive man.

A sigh came from the communication channel.

"Go back."

"Take my questions back with you."

"Find the one among you who can untie it, and let him come here to me with the answer."

"If you want to do something good for your countrymen."
