Libraries, one of the symbols of the development of civilization.

The name may be different in each civilization, but the role is the same.

Soon Lin Xu found the library of the current city, and Bai Xing copied all the materials in it.

At the same time, Shirahoshi also connected to the global Internet on the planet and retrieved all publicly available information.

And the location of the national database was determined.

Although the database is physically cut off from the outside world.

But this is not difficult for Shirahoshi.

By using nanorobots to establish a connection channel, it is easy to get all the data from the database in your hands.

There is not even a defense mechanism that triggers the database.

It's really that the gap between civilizations is too huge, and Gu Mogang's database defense mechanism is like a building block built by a child in Shirahoshi's eyes, and it can be easily bypassed.

"Did you find something useful?" Standing on the side of the road, looking at another grand procession to celebrate the advent of the Holy Son, Lin Xu asked Bai Xing.

At the same time, the southern candle beside Lin Xu was already bouncing and perfectly integrated into the carnival atmosphere, almost exposing his tail and fox ears.

Even Lu Yao was infected by this atmosphere, and cheered from time to time.

That is, Miss Qiu and Mu Xiyue are not as disturbed by the external atmosphere as ever.

"The data related to the Holy Father has been searched, and no specific records of the contact between the native civilization and human beings have been found, and there is no relevant evidence that the purgators have a different view of the native civilization." Shirahoshi replied.

"What else?" Lin Xu looked at the procession walking by and continued to ask quietly.

"I found 2,000 years of video materials about the Holy Day and the Son's descent, according to records, although the native civilization sent a spaceship to try to make contact with the Cleaners when the Son came, there was no record of contact established, as if the Cleansers just came to see and left without leaving a word. For the spaceship sent by the local civilization, it is only like air. ”

"Two thousand years?" Lin Xu noticed something.

"Yes, two thousand years ago, the native civilization has entered the digital age that can leave digital image materials, so the database has the image data of the arrival of the Holy Son two thousand years ago, but at that time, the native civilization could only send a small spaceship to try to contact the Cleanser fleet, but before it could fly far from the planet, the Cleanser fleet left."

"Then came a thousand years ago, when the Son came again, when the native civilization was able to send a fleet to get up close and personal with the Cleanser fleet, but there was no response either."

"Finally, the other day, the same purge did not respond."

"It's been 2,000 years since they entered the space age, and they have controlled nuclear fusion technology, so how is the curvature engine being studied?" Lin Xu asked.

"According to the database, the native civilization did not have the technology to have a curvature engine." Shirahoshi replied.

"That's normal, right? Isn't it said that the curvature engine technology itself is a big filter? I remember that on the other side of the galaxy, only if you have mastered the curvature engine technology, you can be considered an advanced civilization, and you have the ability to sail around the galaxy at will. Even tens of thousands of years into the nuclear era, many civilizations still did not develop curvature engine technology. Lu Yao next to him interjected.

"No, Miss Lu Yao, the local civilization not only does not have curvature engine technology, but also does not conduct any research related to curvature engine technology." Who knew that Shirahoshi was the first to refute.

"No research?" Lu Yao was stunned for a moment, and also reacted.

With the difficulty of the curvature engine, many civilizations have not been studied for tens of thousands of years, or even until the demise of civilizations, so it is normal that they cannot be studied.

But without research, that's not normal.

This shows that this civilization has not invested any research resources in the curvature engine at all.

Just like the earth in the 21st century, everyone is researching controlled nuclear fusion, even if it has never been successful, but the research has been going on.

But this civilization does not even have a study of the curvature engine.

It is as if research in this direction has been completely abolished.

In other words, it is forbidden to conduct relevant research in this direction.

"Can you find a ban? A ban on research directions related to curvature engines? Lin Xu asked.

"There is no explicit ban, but all the cutting-edge research projects related to the curvature engine cannot be approved, and the research can only be stalled." Shirahoshi searched again as fast as he could, and replied.

"So, research related to curvature engines, although there is no relevant ban, is actually banned." Lin Xu nodded slowly.

"So, this civilization is considered to be self-defeating, so that the cleaners can let them go?" Lu Yao on the side also suddenly realized.

Then he was puzzled, "In this case, if the cleaners let this go, it has nothing to do with the local civilization worshipping humans?" ”

"Maybe it has nothing to do with the worship of humans, but we can't explain how the native civilization here knows about the existence of humans. It is also not known why the native civilization would be clear that as long as the technology of curvature navigation is not developed, the cleaners will let them go. Lin Xu shook his head and said.

"Could it be that the cleaners told them?" Lu Yao guessed.

"But the few times in the past two thousand years, the Purgeers have not sent any information to them, unless the civilization has hidden the information they have received and has not stored it in the national database." Lin Xu was thinking about various possibilities.

Nan Zhu, who had been immersed in the carnival atmosphere next to him, looked at Lin Xu's frowning and thinking, and then looked at the laughing crowd in the procession in front of him, as well as the colorful ribbons sprayed from time to time around him, hanging on the people in the parade, everyone laughed.

Nan Candle's eyes rolled and glanced at Mu Xiyue, Mu Xiyue hesitated, but still nodded.

Then Nan Candle pounced directly on Lin Xu's body, pulling Lin Xu and rushing towards the crowd, Mu Xiyue took the opportunity to push Lin Xu behind.

The two worked together to bring Lin Xu into the carnival crowd.

"Lord Lin Xu, it's a rare opportunity to play together, those troublesome things, just wait for the aftermath to worry about it." Nan Candle's fox ears, hidden under her hair, popped up a little bit from time to time, but they were quickly hidden by her again.

The blonde girl smiled like a flower, her face was full of youthful atmosphere, hugged Lin Xu's arm, and took him to blend into the carnival crowd.

On the other side is Mu Xiyue, who is usually very restrained, but in the warm atmosphere, it is rare to show a smile.

Lin Xu also laughed.

Well, now it's party time, so let's not think about those troublesome things just yet.

In this way, Lin Xu also began to enjoy the festive atmosphere.

As the flow of people moved and cheered, the sky was a holographic projection about the history of this civilization, this nation, and all the way from ancient times.

Lin Xu looked at it with emotion, it can only be said that it is not easy for every civilization to develop.

And at this moment, the explanation in the sky proceeded to myths and legends.

Legend has it that in ancient times, the Holy Son came and left behind a stone tablet of the three chapters of the covenant, which was agreed with the ancient ancestors.

Looking at the illusion in the sky, one by one it seems that they are still in the Stone Age, wearing animal skins, kneeling on the high mountain, meeting with the Holy Son who descended from the sky and driving a huge heavenly boat, and took the stone slab in the hands of the Holy Son.

Lin Xu suddenly thought of something.

"Shirahoshi, have you investigated myths and legends?" Lin Xu asked.

"There are so many imaginary and woven stories in mythology." Shirahoshi replied.

But is there a truth hidden in the myth? For example, the slate of the third chapter of the covenant, could it be real? Lin Xu asked.

"I'm going to investigate all the museums, everything related to ancient slates." Shirahoshi replied.

Lin Xu also wanted to go to the museum to see it in person, but he hesitated when he saw that Nan Zhu was still jumping happily.

At this time, Nan Zhu pounced on him again, hugged him and said directly.

"Lord Lin Xu, let's go to the museum!"

"Aren't you playing?" Lin Xu wondered.

"Well, I'm almost done, and it's like this if I continue to play, and it's important to get down to business, I'm still very good at distinguishing the weight." Nan Zhu looked at Lin Xu with a look I am not great.

"Okay, let's go." Lin Xu reached out and rubbed her head.

In this way, the group quietly disappeared into the carnival crowd.

Covered in optical camouflage, he soon arrived at the National Museum, the largest in the capital of the ancient Mogang Republic.

It is said that the most precious cultural relics of the entire ancient model are treasured here, and many unique items can only be found here.

When Lin Xu and his party arrived, Bai Xing had already obtained the database information in the museum first, and had already found a record of the stone tablet that the Holy Son and mortals had agreed with in ancient times.

It is housed in this national museum.

However, it is not exhibited, but is always kept as a treasure in the museum's safe.

"I really didn't expect that the mythical things actually existed." Lu Yao's tone was a little strange.

"The so-called myth is not created out of thin air, even if there is a part of the fabrication, at least part of it is true. Of course, the premise is that the civilization is old enough and pragmatic enough to not be the kind of person who takes dreams as facts. Nan Zhu shook his head and explained.

"For example?" Lu Yao asked.

"For example, the number one power in the universe." Nan Candle replied.

"Ahem." Lin Xu on the side almost didn't choke.

"I see, you're talking about a certain country on Earth before, I understand." Lu Yao's face suddenly realized.

"Huh? You all know this? I thought you didn't know. Nan Zhu looked surprised.

"You forgot that I played a lot of games from that era, of course I know this stalk, so how do you know?" Lu Yao was puzzled.

"That's the era that Lord Lin Xu lived in, I definitely want to understand it well." Nan Zhu said with a natural expression.

The two of them chatted, and the group had successfully invaded the interior of the museum and found the location of the safe.

Using nanobots to directly take over the defense system of the entire museum is a breeze for Lin Xu and his party.

Until now, the staff on duty in the monitoring room are still looking at the normal picture of the museum's interior.

But in fact, Lin Xu and the others had already swaggered in, and they were not noticed by anyone at all.

As for the safe with the physical lock, it was also easily picked open.

Lin Xu and the others bypassed the precious cultural relics preserved in the museum and came to the front of the stone slab.

I could see the words carved on the slate.

Exactly the Chinese characters.

But it's just a few simple phrases.

There is no real meaning.

At the same time, just getting close to the slate, Lin Xu felt the same material used on the slate, which was the same material used in the armor of the cleaner.

Shirahoshi then tested and also determined that the material of the slate was a simplified version of the nanobot.

At the same time, Shirahoshi also read the data from the slate.

That's right, this slate is more like a hard drive, and the words engraved on the surface are more like a ritual.

The data recorded inside the slate is the most important.

"What does the data record?" Lin Xu asked.

"The purge who claims to be the second son of mankind is recorded, and the pact with the native civilization."

"In this document, among all the research directions of the future of civilization, the forbidden part is all related to curvature navigation."

"At that time, this civilization was still in the Stone Age, right? To put it bluntly, it's a group of primitive people, right? Agree with the primitive people on the direction of future scientific and technological research? Nan Candle's eyes widened, and his face was incredible.

But that's what the Purgeers did, and as early as 4,000 years ago, they agreed with the native civilization about the direction of future research, and informed them that if the native civilization broke the agreement, it would be purged. At the same time, the cleaners make rounds every thousand years to determine whether the native civilization is abiding by the agreement. Shirahoshi explained.

"But why would the Cleaners make such an agreement with this native civilization? The previous exile fleet, and the destroyed civilization we encountered, the purgeers did not make such an agreement, huh? Nan Zhu didn't understand.

"Is there really anything special about this civilization?" Lu Yao brought up the matter again.

"I do think that the destroyed civilizations we encountered before, as well as the exiled fleets, may not have made similar agreements with the Cleaners in ancient times." Lin Xu thought about it, but said it.

"Can't tell, the civilization that was destroyed, it was clearly said in the database, they were researched the curvature engine, and after starting the voyage, they met the rest of the higher civilizations, and then they knew about the cleaners, and they didn't know about it before." Nan Zhu asked.

"Yes, they don't know, but is it possible that they have forgotten about it?" Lin Xu nodded, shook his head again, and said.

"Forgot?" Nan Zhu was stunned for a moment.

"How many civilizations on the earth once had memories of ancient times? Most civilizations have long since lost themselves for a long time, some have been ruled by religion, and they have smashed the legends left by their ancestors. Even if some of them still remember the ancient legends, they have long since been smashed by the colonizers, leaving only a little legend. Lin Xu sighed.

"Therefore, the exiled fleet and the civilization that was destroyed may have also made an agreement with the cleaners in ancient times, but in the development of civilization, they have already smashed their own stone tablets, even if there is still a little memory of legends, there is no data in the stone tablets to support them, after they develop, I am afraid they will only regard it as an ordinary myth." Nan Zhu said abruptly.

"Yes, it is extremely difficult to be able to keep the slate all the time in the development of civilization. They had to travel a long time until they had a computer that could read the data inside the slate and understand the warning from the washers. Otherwise, it is just word of mouth, and there is no stone slab to corroborate it, I am afraid that the myth will have long been deformed in circulation. Lin Xu nodded.

"And about the Holy Father of mankind?" Nan Zhu asked again.

"There are some accounts of humanity in the database of tablets, and it is not surprising that the cleansers call themselves the second sons of men, so it is not surprising that humans and cleanders are respectively honored as the Father and the Son. The origin of everything is from this stone slab. Lin Xu stretched out his hand and rubbed this stone slab that had gone through the years, feeling a little emotional.

Although this slate is made of a simplified version of the nanobot, the nanobots are not tightly polymerized, forming a structure that closely resembles a rock.

It weathers naturally with the passage of time, but does not affect the internal data storage, unless the slate is completely destroyed.

And if the slate is to be destroyed, it is actually very easy, because the strength of this slate will not be much stronger than the real stone.

"Why did the cleaners leave behind such a stone slab that could be easily destroyed? If the slate can't be destroyed, won't it be able to be preserved forever and warn future generations? Nan Candle was puzzled.

"Maybe it's a test too!" Lin Xu thought about it and could only come to this conclusion.

"But what are the cleaners testing? What is their purpose? Lu Yao was puzzled.

"The purpose of the cleaners, we may have to wait until we find out for ourselves." Lin Xu withdrew his hand from the slate.

"Lord Lin Xu, won't we take this slate?" Nan Zhu asked with a flicker of his ears.

Since leaving the street and infiltrating the museum, Nan Candle's ears and tail have finally been liberated again, and they don't have to be hidden.

"No, I'd better leave it to them! The data has been read, and this thing is of little use to us, but to them it is a proof of the existence of civilization, and it is still a precious historical artifact. Lin Xu shook his head and said.

"Are we leaving?" Nan Zhu nodded and asked.

"The investigation is almost done, and then look at the feedback on the other two planets, if there is no updated information, we should also go." Lin Xu nodded.

Soon, Lin Xu and his party, who had already completed the preliminary investigation, returned to the Skylark.

At this time, the autonomous mechanical aggregate sent by Shirahoshi has also infiltrated the other two planets and obtained a lot of information.

It's just that there is nothing new in this information, and it is all information that is already known.

There is no new slate-like thing.

Four thousand years ago, only the fourth planet in this galaxy had civilizations, and the civilizations on the other two planets were developed by immigrants after the people on the fourth planet developed space technology.

And apparently, the only thing the cleaners came into contact with four thousand years ago was the ancestors of the Gumogang Republic.

And 4,000 years have passed, and the descendants of the ancient model gang people are still standing at the apex of civilization on this planet, which is the luck of this civilization.

Otherwise, this slate would have been smashed by the conquerors long ago.

Like everything the Spaniards did in the Americas.

Intelligent beings who have been brainwashed by religion have always been so stupid.

"Have you determined the location and coordinates of the cleaners when they left?" On the Skylark, Lin Xu asked.

"The jump information when the cleaner leaves has been scanned, and the direction and coordinates of the next jump of the cleaner can be determined." Shirahoshi replied.

"Open the space passage, let's continue to catch up and see what the cleaners will do next." Lin Xu said.

"Lord Lin Xu, should we rush to the front of the cleaners?" Nan Zhu on the side thought about it and proposed.

"Go ahead? You mean to go to the front and block the cleaners? But we don't know where they will go. Lin Xu shook his head and said.

"Shirahoshi, where is the target of the purge this time?" Nan Zhu asked instead.

"The Cleaners are targeting a galaxy fifty light-years away." Shirahoshi replied.

"Is that the closest galaxy to here?" Nan Candle continued to ask.

"Yes, it's the closest galaxy to here." Shirahoshi replied.

Lin Xu was stunned for a moment, and suddenly reacted to the meaning of Nan Candle.

So without waiting for Nan Zhu to continue to ask, he spoke directly.

"What's the closest galaxy to that galaxy fifty light-years away?" Lin Xu asked.

Obviously, the Cleaners are cleaning from one galaxy to another, so it's not impossible to get ahead of the Cleaners.

"A galaxy eighty light-years away." Shirahoshi replied.

"Then the coordinates of this transition are determined to be a galaxy eighty light-years away, let's go there and see if we can stop the Cleaners." Lin Xu decided.

"Your will, human Lin Xu." Shirahoshi replied.

With Shirahoshi's answer, the space jump channel in front of the Skylark opened.

At the same time, spatial folding continues to begin in the channel.

Two and a half days passed quickly.

The spatial fold in the spatial transition channel has reached eighty light-years away.

So the Skylark sailed straight into the space jump channel.

In the blink of an eye, it crossed a distance of 80 light-years and reached the outer reaches of the galaxy, which is located 80 light-years away.

"How? Are the cleaners coming? At this time, Lin Xu also asked a little nervously.

Soon, the feedback of hyperspace radar and quantum radar arrived.

"There is no sign of the Cleaners in the galaxy ahead, and the Cleaners have not yet arrived." Shirahoshi replied.
