Zhuge Yun was silent for a long time, his mind had been turning rapidly, his frightened eyes contained a lot of confusion, and many questions flashed in his mind, all of which were unsolvable questions that had bothered him for a long time.

His eyes closed, trying to figure out how to answer the voice.

Zhuge Yun didn't know if this voice was made by the "people" who built these black cities or something else, and what was "his" motive? It wasn't clear if the other party would be able to resolve his question, but he couldn't even figure out whether to say hello or ask a question at the moment.

He only knew that since it was the other party who had recruited him to this place, he must have some purpose, and listening to what the voice said, it seemed that he not only knew himself, but also looked forward to his arrival.

"Who are you? Who's talking to me? Zhuge Yun sorted out his emotions and asked cautiously.

It didn't take long, probably, maybe only 2 or 3 seconds, but he wasn't sure. After Zhuge Yun asked those words, he felt that a long time had passed, and he even thought that the flow of time had slowed down, and the anxiety in his heart began to appear.

Some of the scenes in the space began to change, the images of the "little jellyfish" became more and more blurred, the clear and soft voice in his head sounded again, and his use of language became more fluent: "Have the creatures of EC238 changed?" The status of the individual is suppressed under the collective, at what stage has your civilization evolved? ”

A strange speech that obviously made Zhuge Yun scratch his head came out, the voice was extremely clear and natural, and he understood the meaning of every word and every word, but when it was connected, he didn't know what it meant.

He stood there dumbfounded like an idiot.

Although the other party's tone could not hear any change, it was like a mechanical tone, but it still made him have countless great doubts in his heart—he didn't understand what the other party wanted to express at all.

What is EC238? What is Personal Status? What does the evolution of civilization mean?

"Wait, the evolution of civilization...... Is this talking about human civilization? His voice rang out through the empty "room", and no echo was heard.

After Zhuge Yun thought about this sentence carefully, a possibility came to his mind, the other party did not understand the human race, and he was asking some questions about basic knowledge.

Thinking of this, he felt like a man who had fallen into the endless mist, suddenly grabbed a torch, and the road in front of him suddenly opened up.

That's right, the other side is talking about "what stage of evolution your civilization has reached". He heard and understood this sentence very clearly, but how to answer it was a new question.

But after less than 3 seconds, the problem was solved.

The other person's voice echoed in his head again, ethereal and empty: "I'm going to ask some simple questions, and if you can answer them, whatever the answer is, I'll get a basis for speculation." ”

Zhuge Yun's mind gradually cleared up, and at the same time, he was not as sluggish as just now, he realized that the other party wanted to get information about the development of human civilization from himself.

"Wait, before you ask, can you tell me who you are?"

"Me? I don't have the concept of the word in my memory bank, I am who I am. ”

Zhuge Yun was stunned all of a sudden, this answer was completely beyond his comprehension, "memory bank"? "I am who I am"? , this is complete nonsense, such an idiotic question, such an idiotic answer.

"So...... Why do you want to know the answers to these questions? Is there any purpose? ”

"In order to let me know you better and guide you."

Zhuge Yun repeated the words of the voice suspiciously: In order to let me better understand you? "Guide you" ...... What does this mean? Does this mean anything else? Why does this voice want to know itself?

It seems that the problems are becoming more and more complicated, and he can't figure it out, so it's better to let "it" ask himself questions first.

So, Zhuge Yun nodded and said, "Okay, you ask." ”

"The first question, what is the shape of the world you live in?"

As soon as the voice finished speaking, a pile of lines appeared in front of him, and these lines seemed to be made with some kind of software, and they could be combined at will. Zhuge Yun carefully spelled out a circle with his fingers, which was the simplest and most reasonable shape he could think of, and the problem itself was not difficult.

"The second question is, is it possible for you to communicate in multiple dimensions in your world?"

This time, there was no picture in front of Zhuge Yun's eyes, and the voice was quietly waiting for his answer, without urging or talking too much nonsense.

"Multi-dimensional communication? I don't quite understand ......"

"The third question is, what is the composition of living things in your world?"

"Wait, I didn't understand the last question, can you explain it to me in detail......"

Before Zhuge Yun finished speaking, he choked, and he didn't know how to express it, but after he paused for 2 seconds, the voice sounded again: "I don't need your answer anymore, your answer is already clear." ”

"Hmm-" Zhuge Yun let out a long breath when he heard this.

The picture of the third question is revealed, this time it seems to be a multiple-choice question: there are more floating things around him, first of all, the space is full of red hues, there are countless granular balls levitating, and a large ball is surrounded by several small balls, and the distance is far and near.

Zhuge Yun knows that this is the basic particle form of matter, from the planetary universe to the smallest molecules, atoms, electrons and other extremely small particles, which can be replaced by this image, which is the relationship between "physical object" and "field" in the usual sense.

Attached to him, in addition to the red area, there were some other colored areas, and there were also many suspended elementary particles in them, but in these forms, he saw a kind of elementary particles like a double form, and knew that this was the multimolecular structure of the cell, which was different from the form of atoms or electrons and protons of metals.

Since the other party is asking "the composition of the organisms in your world", it is obvious that he is talking about the "carbon-based life forms" that account for the largest number of living things on the earth, and all the things that can be called "living things" on the earth are "carbon-based life forms".

From viruses and microorganisms to large birds, beasts and fish, to humans, they all belong to this category.

So, he quickly chose this particle structure with a composite form, and flicked his fingers on the particle.

The voice asked the next question as soon as he made his choice.

He didn't know how long it had been, but he had made a note of the number of questions—17 questions had been asked, and the 18th question was the last one in his mouth.

Zhuge Yun tried his best to answer or choose the questions raised by that voice in detail.

There are many strange questions, but the answer to each question seems to be getting closer and closer to the scope of knowledge he knows, and there will be no more questions like "is your world capable of multidimensional communication?"

The last question that Zhuge Yun answered: The laws of physics that have been discovered in your world recently, just name one.

Zhuge Yun thought about this question for a long time, but it made him understand the fact more clearly, that is, the other party already had a general understanding of the human civilization he was in, otherwise it would not have asked such a question.

He even had a vague feeling that the other party was an "artificial intelligence system", trying to obtain accurate data through learning, investigation, retrieval, induction and other methods.

He couldn't remember the complicated formula, and based on the fear of the unknown purpose of the other party, when answering this question, he had an extra mind, and after thinking for a while, he casually wrote down a formula from hundreds of years ago - "e=mc2".

He didn't know if the other party could recognize the meaning of the symbols and letters that appeared in it, but the next moment he was completely shocked.

"Very well, you're already in the realm of quantum theory." The voice replied mechanically.
