I take the earth to wander

Libraries are one of the symbols of civilization development.

Maybe the name is different in each civilization, but the function is the same.

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

At the same time, Bai Xing also connected to the global Internet on this planet and retrieved all public information.

And the location of the national database was identified.

Although the database is physically isolated from the external network.

But that didn't bother Shirahoshi.

Using nanorobots to establish a connection channel, it is easy to get all the data in the database.

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

In fact, the civilization gap is too huge. Gu Mogang's database defense mechanism, in Bai Xing's view, is like building blocks built by children, which can be easily bypassed.

"Have you found anything useful?" Lin Xu, who was standing on the side of the road, watching another grand parade celebrating the coming of the Holy Son, asked Bai Xing.

At the same time, Nan Zhu next to Lin Xu had jumped into the carnival atmosphere perfectly, almost showing his tail and fox ears.

Even Lu Yao was infected by the atmosphere, cheering along from time to time.

In other words, Ms. Qiu and Mu Xiyue were not as disturbed by the external atmosphere as before.

"The data related to the Holy Father has been searched, and no specific records of contact between the native civilization and humans have been found, and there is no relevant evidence that the cleansers looked at the native civilization differently." Bai Xing replied.

"What else?" Lin Xu looked at the parade passing by, and continued to ask calmly.

"I have found two thousand years of video data about the Ordained Day and the coming of the Holy Son. According to records, although the local civilization sent spaceships to try to contact the cleansers when the Holy Son came, in fact there is no record of the contact being established, as if the cleansing The visitors just took a look and left without leaving a word. For the spaceship sent by the local civilization, it is just like air."

"Two thousand years?" Lin Xu noticed something.

"Yes, two thousand years ago, the native civilization had already entered the digital age where digital images could be left behind, so the database contained images of the coming of the Son of God two thousand years ago, but the local civilization at that time could only send A small spaceship tried to contact the Cleaner fleet, but before flying far beyond the planet, the Cleaner fleet left."

"Then a thousand years ago, the Holy Son came again. At that time, the native civilization was able to send a fleet to make close contact with the Cleanser fleet, but there was also no response."

"The last one was the one a few days ago, and the cleaners didn't respond."

"It has been two thousand years since they entered the space age, and they also have controllable nuclear fusion technology, so how is the research on the curvature engine?" Lin Xu asked.

"According to the records in the database, the native civilization does not have the technology related to the curvature engine." Bai Xing replied.

"Is this normal? Doesn't it mean that the curvature engine technology itself is a big filter? I remember that in the Milky Way, only those who have mastered the curvature engine technology can be considered advanced civilizations, and have the ability to navigate the galaxy at will. Many civilizations have not developed the curvature engine technology even after tens of thousands of years in the nuclear energy age." Lu Yao next to him interjected.

"No, Miss Lu Yao, not only does the local civilization not have the curvature engine technology, but it has not conducted any research related to the curvature engine technology." Unexpectedly, Bai Xing retorted first.

"No relevant research?" Lu Yao froze for a moment, but also came to her senses.

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

But that's not normal without research.

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 controllable nuclear fusion. Even if it has never been successful, the research is still going on.

But this civilization doesn't even have research on the curvature engine.

It seems that research in this direction has been completely abolished.

In other words, related research in this direction is prohibited.

"Can you find a ban? A ban on the research direction related to the curvature engine?" Lin Xu asked.

"There is no clear ban, but all cutting-edge research projects related to the curvature engine cannot be approved, and the research can only be stagnated." Bai Xing searched at the fastest speed again, so he replied.

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

"So, this civilization is regarded as abolishing martial arts, so that the purgers can let them go?" Lu Yao on the side also suddenly realized.

Then he wondered, "So, if the Cleaners let it go, it has nothing to do with the local civilization's worship of human beings?"

"Maybe it has nothing to do with worshiping humans, but we still can't explain how the native civilization here knows the existence of humans? I also don't know why the native civilization knows that as long as the curvature navigation technology is not developed, the Cleaners will let them go. "Lin Xu shook his head and said.

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

"However, during the several visits in the past two thousand years, the Cleaners did not send any information to them, unless this civilization hid the information they received and did not store it in the national database." Lin Xu was thinking about various possibility.

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

Nan Zhu rolled his eyes and winked at Mu Xiyue. Mu Xiyue hesitated for a moment, but still nodded.

Then Nan Zhu threw himself on Lin Xu, pulled Lin Xu and rushed into the crowd, Mu Xiyue took the opportunity to push Lin Xu behind.

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

"Master Lin Xu, it's a rare opportunity to come and play together. Let's worry about those troublesome things later." Nan Zhu's fox ears hidden under his hair appeared from time to time, but they were quickly caught by her again. hide.

The blond girl smiled like a flower, her face full of youthful breath, hugged Lin Xu's arm tightly, and led him into the carnival crowd.

On the other side was Mu Xiyue, who was usually very reserved, but in the warm atmosphere, she rarely showed a smile.

Lin Xu also laughed.

Well, it's party time, so forget about the annoying things.

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

As the flow of people moves and cheers, the sky is projected by holographic projections about the history of this civilization, this nation, from ancient times.

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

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

Legend has it that the Son of God descended in ancient times and left behind a three-chapter slab of covenant to make an agreement with the ancient ancestors.

Looking at the illusions in the sky, there are ancient Mogang people who seem to be in the stone age, wearing animal skins, kneeling on the high mountains, meeting with the Holy Son who descended from the sky and driving the huge sky boat, and took it from the hands of the Holy Son. slate.

Lin Xu suddenly thought of something.

"Bai Xing, have you investigated the myths and legends?" Lin Xu asked.

"There are too many imaginative and woven stories in the mythology." Bai Xing replied.

"But is the truth hidden in the myth? For example, is the stone tablet with three chapters actually real?" Lin Xu asked.

"I will investigate all the museums and everything related to the ancient stone slabs." Bai Xing replied.

Lin Xu also wanted to go to the museum in person, but he hesitated seeing Nan Zhu still bouncing around happily.

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

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

"Are you not playing?" Lin Xu asked doubtfully.

"Well, I've almost finished the game, and it will look like this if I continue to play, and the business is important, I can still tell the difference." Nan Zhu looked at Lin Xu with a look on my face.

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

Just like that, the group quietly disappeared into the carnival crowd.

Covered in optical camouflage, he soon arrived at the largest national museum in the capital of the Republic of Kumaku.

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

When Lin Xu and his party arrived, Bai Xing had already obtained the database information in the museum first, from which he had already found the record about the stone slab that the Holy Son made an agreement with mortals in ancient times.

It's in the National Museum.

It's just that it has not been exhibited, but has always been regarded as a treasure and is kept in the safe of the museum.

"I didn't expect that the things in the myths actually existed." Lu Yao said in a strange tone.

"The so-called myths are not created out of thin air. Even if there are fabricated parts, at least some of them are true. Of course, the premise is that this civilization is old enough and pragmatic enough, not the kind of people who treat dreams as facts. Yes." Nan Zhu shook his head and explained.

"For example?" Lu Yao asked.

"For example, a certain country that is the largest country in the universe." Nan Zhu replied.

"Ahem." Lin Xu on the side was almost choked.

"I see. You're talking about a certain country on Earth before. I understand." Lu Yao suddenly realized.

"Hey? 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 trick, how did you know that." Lu Yao was puzzled.

"That's the era Master Lin Xu lived in, I must understand it well." Nan Zhu said with a face of course.

The two of them were chatting, and a group of people had successfully invaded the interior of the museum and found the safe.

Using nano-robots to directly take over the defense system of the entire museum is a breeze for Lin Xu and his team.

Up to now, the staff on duty in the monitoring room are still watching the normal inside of the museum.

But in fact, Lin Xu and the others had already walked in swaggeringly, without being noticed by anyone at all.

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

Lin Xu and the others bypassed the precious cultural relics kept inside the museum and came to the stone slab.

I can clearly see the words engraved on the stone slab.

It is Chinese characters.

But it's just a few simple phrases.

There is no real meaning.

At the same time, just by being close to the stone slab, Lin Xu could feel the same material used for the cleaner's armor on the slate.

Afterwards, Bai Xing conducted a test and also confirmed that the material of the stone slab was a simplified version of nano-robots.

At the same time, Bai Xing 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 ceremony.

The data recorded inside the slate is the most important.

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

"Records the purge who claims to be the second son of mankind, and the agreement with the native civilization."

"This document lists the forbidden parts of all the future research directions of civilization, all of which are related to curvature navigation."

"At that time, this civilization was still in the Stone Age, right? To put it bluntly, it was a group of primitive people, right? Make an agreement with the primitive people on the direction of future scientific and technological research?" Nan Zhu's eyes widened with disbelief.

"But this is what the cleansers do. As early as four thousand years ago, they agreed with the local civilization on the future research direction, and at the same time informed that if the local civilization violates the agreement, it will be cleaned. At the same time, every thousand years, the cleansers will Take a tour to determine whether the local civilization has complied with the agreement." Bai Xing explained.

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

"Could it be that there is something special about this civilization?" Lu Yao brought up this matter again.

"I think that the destroyed civilizations and exile fleets we encountered before may not have made similar agreements with the Cleaners in ancient times." Lin Xu thought for a while, but said.

"It can't be said that the civilization that was destroyed, it is clearly stated in the database that they only knew about the Cleanser after they researched the curvature engine and started the voyage, and met the rest of the higher civilizations. I don’t know.” Nan Zhu raised a question.

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

"Forgot?" Nan Zhu froze for a moment.

"On the earth, how many civilizations still have the memory of the ancient times? Most civilizations have lost themselves for a long time, some are ruled by religion, and they smashed the legends left by their ancestors. Even if some still remember the ancient legends, the colonists have already smashed the slate of civilization, leaving only a little legend." Lin Xu sighed.

"So, the exile fleet and the destroyed civilization may have made an agreement with the Cleansers in ancient times, but they have already smashed their own stone slabs in the development of civilization, even if there is still a bit of legend Memory, without the data in the slate to support it, after they develop, I'm afraid it will only be regarded as an ordinary myth." Nan Zhu said in a daze.

"Yes, it is extremely difficult to keep the slate in the development of civilization. They have to go through a long time until they have a computer that can read the data in the slate. Only then can they understand that from cleaning Otherwise, it will only be spread by word of mouth without stone evidence, and I am afraid that the myth has already been distorted in the spread." Lin Xu nodded.

"Then about the holy father of mankind?" Nan Zhu asked again.

"There are some records about human beings in the database of the slate, and the cleanser claims to be the second son of mankind, so it is not surprising that human beings and the cleanser are honored as the Father and the Son respectively. The origin of everything is from It’s because of this stone slab.” Lin Xu stretched out his hand to caress the stone slab that has gone through the years, feeling a little emotional.

Although this stone slab is made of simplified nano-robots, the nano-robots are not tightly aggregated, forming a very rock-like structure.

Natural weathering with the passage of time, but will not affect the internal data storage, unless the slate is completely destroyed.

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

"Why did the purgers leave such a slate that could be easily destroyed? If the slate could not be destroyed, wouldn't it be able to keep it forever and warn future generations?" Nan Zhu asked puzzled.

"Maybe this is also a test!" Lin Xu thought for a while, and could only come to this conclusion.

"But, what exactly are the purgers testing? What is their purpose?" Lu Yao asked puzzled.

"The purpose of the cleanser may have to wait for us to find out." Lin Xu withdrew his hand from the slate.

"Master Lin Xu, don't we take this slate?" Nan Zhu asked with a flick of his ear.

Since leaving the street and sneaking into the museum, Nan Zhu's ears and tail were finally released again, no need to be hidden.

"No, let's leave it to them! The data has been read, so this thing is useless to us, but to them, it is a proof of the existence of civilization, and it is also a precious historical relic." Lin Xu shook his head and said .

"Then are we leaving?" Nan Zhu nodded and asked.

"The investigations are almost completed. Let's look at the feedback from the other two planets. If there is no updated information, we should go." Lin Xu nodded.

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

At this time, the self-discipline mechanical aggregate sent by Bai Xing has also sneaked into the other two planets and obtained a lot of information.

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

There is no new thing like a slate.

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

Apparently, the only people the Cleansers had contact with four thousand years ago were the ancestors of the Gumakon Republic.

And four thousand years have passed, and the descendants of Gu Mogang are still standing at the apex of civilization on this planet. This is the luck of this civilization.

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

Just like everything the Spaniards did in America.

Intelligent life brainwashed by religion has always been so stupid.

"Are you sure about the location and coordinates of the cleaners when they left?" Lin Xu asked on the Skylark.

"The transition information of the cleanser when he left has been scanned, and the position and coordinates of the cleanser's next transition can be determined." Bai Xing replied.

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

"Master Lin Xu, should we rush to the front of the purge?" Nan Zhu thought for a while and suggested.

"Go ahead? You mean go ahead and block the cleaners? But we don't know their follow-up route." Lin Xu shook his head and said.

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

"The cleanser's target is a galaxy fifty light-years away." Bai Xing replied.

"Is that the nearest galaxy?" Nan Zhu continued to ask.

"Yes, it is the nearest galaxy to here." Bai Xing replied.

Lin Xu froze for a moment, and immediately realized what Nan Zhu meant.

So without waiting for Nan Zhu to continue asking, she opened her mouth directly.

"Where is the nearest galaxy to the galaxy fifty light-years away?" Lin Xu asked.

Obviously, the cleansers are cleaning one galaxy after another, so it is not impossible to rush to the front of the cleansers.

"A galaxy eighty light years away." Bai Xing replied.

"Then the coordinates of this jump are determined to be a galaxy 80 light-years away. Let's go there and see if we can stop the Cleanser." Lin Xu decided.

"Your will, human Lin Xu." Bai Xing replied.

Accompanied by Bai Xing's answer, the space transition channel in front of the Skylark opened.

At the same time, space folding continues to start in the passage.

Two and a half days passed quickly.

The space folding in the space transition channel has reached eighty light-years away.

So the Skylark sailed straight into the space transition channel.

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

"How? Has the cleaner come?" Lin Xu also asked a little nervously at this time.

Soon, the feedback from hyperspace radar and quantum radar will arrive.

"There is no sign of the arrival of the cleanser in the galaxy ahead, and the cleanser has not arrived yet." Bai Xing replied.
