Yuan Haochen quickly understood that the so-called key should be just a metaphor. At this moment, he should be communicating with an independent program similar to the access control of this five-dimensional physical space.

According to the "key", the builders of the asteroid have long ceased to be here. And because of its age, even the computer intelligence system that was originally responsible for this five-dimensional physical space has collapsed. Of course, why it collapsed, and why the "key" was able to exist independently after the collapse, and other doubts, are all unknown to them now.

Perhaps, it is precisely because the computer intelligence system in the five-dimensional physical space has long since collapsed that they have been unwelcome when they come to the interior of the asteroid. On the other hand, if the other party is a computer intelligence system built by a super civilization that can build a five-dimensional physical space, then the process of learning the language just now will be much faster.

After thinking for a while, Yuan Haochen continued to ask the other party, "You said that you are the key, the key to this five-dimensional space?" ”

Key: [Yes, I am indeed the key here, but you can't get in.] 】

Yuan Haochen: "Since you are the key, can you help us get in?" ”

Key: [No.] 】

Yuan Chen: "Why? ”

Key: [Because, you will die, you will die.] 】

Yuan Haochen: "You mean that we don't have the ability to exist in the five-dimensional space?" ”

Key: [...... Silence, no answer......]

Yuan Haochen: "Excuse me, what's inside?" ”

Key: [Memory......]

Yuan Haochen: "What memory? ”

Key: [Precious memories, precious memories about our universe.] 】

Yuan Haochen: "Since it is a commemoration, since it will eventually be forgotten, can you share the story of your universe with me?" ”

Key: [I'm just the key, and the key doesn't have access to the central database information.] 】

Yuan Haochen: "That's a pity. By the way, you mentioned before that people are gone, can you elaborate on why they are gone? ”

Key: [People, all gone, or dead, a long, long time has passed.] 】

Yuan Haochen: "Where did they go?" ”

Key: [The key doesn't know where the owner has gone.] 】

Yuan Haochen: "What about your universe?" Is your universe still around? ”

Key: [It's still there, but it's about to be gone.] 】

Yuan Haochen: "You mean, this is your universe, this is here?" A memory that will eventually be forgotten? ”

Key: [A memorial that will eventually be forgotten.] 】

Yuan Chen: "Why do you say that your universe is about to cease to exist?" ”

Key: [...... Silence, no answer......]

Yuan Haochen: "What caused your universe to finally come to an end?" ”

Key: [...... Silence, no answer......]

This time, the "key" was silent for a long time, and Yuan Haochen also waited for a long time.

After previous communication, Yuan Haochen also roughly felt a little bit of the temper of the "key". When the "key" is silent on the question asked, then the answer to the question is mostly yes. When the "key" is unwilling or unable to answer the question head-on, you can give him a multiple-choice question.

Hara Chen: "Is it the internal cause of your universe that caused the destruction, or was it influenced by external forces?" ”

Key: [Mainly due to the influence of external forces.] 】

Yuan Haochen: "External forces originate from other universes. ”

Key: [Yes and no.] 】

Yuan Haochen: "What do you mean yes and no?" It's puzzling. ”

For this answer, Yuan Haochen was speechless for a while, since it was an external force, then it should be classified as a force from other universes. But this "yes and no" answer really made him feel foggy.

Key: [I'm just the key, I don't know much.] 】

Yuan Haochen: "I'm sorry, Key, can you tell us more about your stories, or those memories that will eventually be forgotten?" ”

Key: [Say more, what should I say, what can I say?] 】

Yuan Haochen: "Please say something." ”

Key: [Our world is like a run that has lasted for hundreds of millions of years, with high-speed progress driving even crazier steps, and countless achievements have created countless great miracles. It seems that we have mastered the whole world, the whole universe...... However, it was not until the end that we realized that the real power was not in our hands, and the world we created could not survive after all, and at the end of civilization, we encountered unexpected opponents......]

Yuan Haochen: "An unexpected opponent, what kind of opponent is that?" Keys, can you tell me? ”

Key: [...... Silence, no answer......]

This time it was a real silence, no matter how Yuan Haochen asked in different ways, he never got any answer after all.

For this reason, Yuan Haochen felt extremely disappointed, because he strongly believed that a great secret about the universe was in front of him, and it was very likely that the key answer of cosmology was hidden in this five-dimensional physical space.

Of course, Yuan Haochen and the Volcano Ball General would not give up easily, they kept trying, and even sent more improved quark robots into the five-dimensional space several times in succession. But it wasn't until Yuan Haochen was keenly aware that the energy flow frequency he had sensed before had completely disappeared that he had to admit that the asteroid had finally died again, returning from a living state to a dead state.

Perhaps the "Key" feels that they do not have the ability to enter the five-dimensional space inside the asteroid, and is unwilling to continue to communicate with them.

Perhaps the "key" has already told them everything he knows, and there is no need to continue to communicate.

Perhaps, the "key", like the computer intelligence system in the five-dimensional physical space, has also collapsed.

Nothing is known.

……

[Is this the end?] 】

After a long time, General Volcano finally couldn't help but speak out to break the silence.

"It's over, that's it for now." Yuan Haochen shook his head and said noncommittally.

What do you think about what the key said? 】

During the entire exchange process, General Volcano Ball had been listening to the conversation between Yuan Haochen and the "Key", and at this moment he was also full of doubts.

"Which ones do you mean?"

Yuan Haochen looked up at the roof of the oval space and asked.

[What happened to their universe, their universe? 】

General Volcano Ball did not understand how grand a universe would be, and what kind of force would bring her to ruin.

"Like you, I don't quite understand it, this issue can be complicated......" Yuan Haochen continued in a low voice, "If this small independent space is their universe, then ...... I don't know, I don't know what's going on in their universe......"

Indeed, in the case of this small space, it is indeed a small universe, but according to the "key", their universe should have been very grand before the distant time.

[The key also mentions the enemy, yes, the external force he calls "yes and no", it should be the external force that destroyed their universe......]

For a moment, General Volcano's mind seemed a little messy, and he really wanted to grab the "key" in front of him and ask again from beginning to end.

"Do you remember the last words of the key?" Yuan Haochen asked with a solemn face.

[Of course I do.] General Volcano Ball repeats with great certainty what the "Key" said at the end, [It was not until the end that they discovered that the real power was not in their hands, and the world they created was difficult to stay, and at the end of civilization, they encountered an unexpected opponent. 】

"Yes, it's that unexpected opponent, and the fate of their universe must be directly related to that unexpected opponent." Yuan Haochen said.
