Li Chen had seen the real "Puliter's Secret Code" with his own eyes, and he nodded in agreement when he heard S2K's words.
And these secret codes are not only huge in size, they must be made of special materials.
It's just that, on the surface, it looks like an ordinary paper book.
If it weren't for the use of special materials to make these books, it would never be possible for these books to survive billions or even tens of billions of years and still be intact.
And it can still run stably, automatically recording every star field, what happens every minute and every second...
"No wonder it's so heavy."
Li Chen nodded to himself, then looked up at S2K.
"And what about the other questions?"
He looked at each other and asked.
At this time, Noah also looked at each other curiously.
Both are waiting for S2K to continue to answer.
"Master, do you think there is a fifth-level civilization in our Orion spiral arm?"
S2K did not directly answer Li Chen's question, but raised a new question.
His question caused Li Chen to fall into silence on the spot.
Li Chen looked at Noah subconsciously, and Noah spread his hands helplessly.
[Host, don't look at me, I don't know...]
[Things beyond the scope of the tenth district are beyond my comprehension. Just crossing the distance of tens of thousands of light years in the entire tenth district will consume a lot of energy, and I have no spare energy to figure out too much The problem…】
Noah replied helplessly and apologetically.
Li Chen, on the other hand, looked at S2K confidently.
"I have no idea."
He said.
This answer made Noah and S2K dumbfounded.
But the two didn't dare to really laugh at Li Chen.
"Master, I can give you an accurate answer."
"The answer is, no."
Although he had already guessed the answer, Li Chen still found it a bit unbelievable.
"Is there not even a fifth-level civilization in the Orion spiral arm?"
he asked hesitantly.
Orion's spiral arm is divided into ten regions.
There are various levels of cosmic civilizations in each region.
So far, Li Chen already knew that in the ninth district next door to them, there were four peak civilizations, and there were two of them.
One is called Jagged Civilization, they just offended someone.
Now people are probably preparing to make trouble for them.
The other is the civilization where S2K used to be, the Massim civilization.
This civilization originally had nothing to do with Earth civilization, but now... it has.
Because they absorbed S2K as a member, and the Massim civilization and S2K are now in an endless relationship...
During the period of more than one hundred years, S2K has carried out many sabotage and revenge actions against the Maxim civilization.
It has brought very huge troubles to the Massim civilization.
What's more, he also knows about those secret tomes.
As for the situation in the other districts, Li Chen still has no idea.
He always thought that the civilization level of the frontier area would be stronger.
There are even Level 6 and Level 7 civilizations.
But now it seems that this is not the case...
"Yes, master, you heard me right and I said right."
"The entire Orion spiral arm, and even several other spiral arms that are on the same level as Orion, do not have a fifth-level civilization. The most powerful is the civilization at the peak of the fourth level."
"The same goes for the largest spiral arms."
S2K replied in the affirmative.
[Is it because of the "key" problem you just mentioned? 】
Noah couldn't help asking questions at this time.
This is obviously far from what he expected.
"Yes, it's because of the 'key' problem."
"Many civilizations have developed to this day. Although they have mastered the secret codes of their respective civilizations, they still don't know the specific uses of these secret codes, including many fourth-level civilizations."
"The reason why the Massim civilization discovered this secret was only by chance..."
S2K continued to explain.
With what he said, Li Chen and Noah became curious students in seconds.
The two listened carefully to S2K's explanation.
Gradually, I began to understand more about the situation.
Suddenly S2K started asking questions again.
"Master, do you know the upper limit of level 4 civilization?"
Hearing this, Li Chen thought for a while and had an answer in his heart, but he still chose to shake his head.
After all, I really don't know much about these things.
So I simply stopped playing tricks in front of this kid.
[The upper limit of level 4 civilization should be 'River System Civilization', right? 】
Noah suddenly spoke up.
"That's right, what you said is right at all, it's the river system civilization."
"The upper limit of the fourth-level civilization can span an entire galaxy, and has the ability to launch at least one war across the entire galaxy!"
"This is the real pinnacle of Level 4 civilization!"
"The so-called Massim civilization, iron-blood civilization, etc., they are far from the real peak."
With S2K's explanation, Li Chen and Noah both understood.
River system civilization...
Li Chen silently read a few words in his heart.
He found that this was basically the same as the answer he was about to come up with just now.
It's just that Li Chen still didn't say a word at this time.
He intends to continue listening to S2K's next introduction.
"As for the fifth-level civilization, it is a civilization with power beyond the peak of the fourth-level civilization. This civilization..."
S2K continued to explain.
The fifth-level civilization is called "dimensional civilization".
That is a civilization far beyond anyone's imagination.
Even a civilization at the peak of the fourth level is far less powerful than a finger of others.
Not only can they launch galaxy-level wars at will, they can easily travel across several star rivers within a certain period of time.
It is even possible to conduct cross-dimensional exploration to obtain higher-level energy and resources.
Those are the current civilizations, temporarily unimaginable...
And the so-called "key" is the object that was born after collecting all the secret codes of the star field.
It is a civilization at the peak of the fourth level, the most critical factor for developing into a fifth-level civilization.
No matter which civilization it is.
As long as all the "secret codes" are successfully synthesized into "keys", they can be promoted to a fifth-level civilization.
"Beyond the fifth-level civilization, there is a sixth-level civilization, right?"
After listening to S2K's explanation, Li Chen let out a long breath.
Then, asked curiously.
"A sixth-level civilization... Maybe it exists."
S2K shook his head.
"That's beyond the limit of my cognition, master, and I can't give you an accurate answer."
"The reason why I want to collect the 'key' of the tenth district is to create a fifth-level civilization. Only in this way can I fight against the Maxim civilization!"
Then, S2K explained again.
