Two days later, Lu Yuan discovered a grotto not far from the stone house.

This grotto is not natural, but completely artificially excavated. Like the Dunhuang Grottoes, this grotto also has a large number of murals.

Yes, it's the murals and not the petroglyphs here, and the scale of this grotto certainly can't be compared with the Dunhuang Grottoes.

However, the murals inside are just as beautiful. But what really shocked Lu Yuan was the content of the mural.

These murals depict a large number of flying machines, as well as scenes of war.

There is a mural, which is even clearly depicting a war taking place in outer space.

In addition, for the first time, a complete image of the Great Witch appeared on these murals.

In the deepest part of the cavern, the largest mural depicts the Great Witch leading some of his allies into battle with the people piloting the saucer-shaped aircraft.

The reason why Lu Yuan was able to judge that the leader was a great witch was because there was a divine text in the corner of the mural.

"In the second year of the publication, ten Mu Lu Ku, Sha Kuyue, the Great Witch Xia Jie led the Mu Kingdom, and the Great Western Kingdom fought the outsiders!"

In particular, the Xia Jie mentioned here surprised Lu Yuan, and there were jade slips left by Xia Jie in the prehistoric underground shelter of the Amazon before.

"It seems that this Xia Jie's status among the Yu Dynasty and the Great Witch should be very high, maybe he is still a commander!"

Lu Yuan didn't speculate, because there were several murals in the cave where the Great Witch led the humans to fight against the outsiders who were piloting the saucer-shaped aircraft.

Moreover, the Xia Jieyu Jian obtained before also mentioned that there were originally human beings living on Mars, and since there were human beings living on Mars, what about other planets.

At this time, Lu Yuan thought of a rumor that astronomers launched a probe to Venus and found more than 20,000 suspected city ruins on the surface of Venus.

So could these so-called outsiders be Martians or Venusians, it is precisely because their planet has become unsuitable for survival that they have caused them to attack the Earth on a large scale.

Lu Yuan even went one step further and thought that maybe 12,000 years ago, there really was an interstellar war in the solar system.

He also mentioned in the stone tablets he found on the remaining islands in the South Pacific that the sinking of the Mu continent was not entirely a natural disaster, and outsiders were the real culprits.

Lu Yuan found that the more prehistoric treasures of the earth he explored, the more doubts he had, and the more mysterious the earth and the solar system became.

Lu Yuan was already vaguely aware of the significance of his discovery this time, he did not want to hide it, but reported the matter of the cave to the international organization after recording the video.

As for those crystal weapons, he is not going to stay, these are all treasures, and he has planned to build a prehistoric crystal weapon exhibition hall in Yingzhou.

Doing so not only ensures the safety of this batch of crystal weapons, but also allows people to learn more about prehistoric civilizations.

At the same time, it can also bring some income to Yingzhou.

It would be much better to do so than to stay here or hand it over to international organizations.

Half a month later, a group of experts from international organizations came to this place under the protection of a team of multinational soldiers.

The scientists were shocked the moment they saw the mural.

They didn't even stop to drink their sip and began to check the age of the mural.

In the end they came to the conclusion that the cave was excavated 10,000-12,000 years ago.

The frescoes date between 7,000 and 12,000 years, and some of them were added later.

What shocked scientists the most was that the pigments of these murals, some of the components of these pigments, had so far not been found anywhere else on Earth.

After Lu Yuan learned this, he believed his own speculation.

12,000 years ago, three of Earth's most powerful civilizations or empires fought a major war with aliens.

The final result should be that the aliens are wiped out, and the continents of Mu, Lemuria, and Atlantis are also sunk in the ocean.

The last remaining Yu dynasty also declined in the war.

The Great War caused great changes in the earth's environment, and finally led to the complete decline of prehistoric cultivation civilizations.

As for modern civilization, it should have developed again after the decline of prehistoric civilization.

Because the earth is no longer able to cultivate, the technological civilization that was originally a vassal in the prehistoric civilization has become the mainstream.

Lu Yuan even suspected that the immeasurable eons mentioned in Buddhism were referring to the great war that affected the entire solar system 12,000 years ago.

And to say that modern civilization is the era of the end of the law is also because the great war has changed the environment of the entire earth, causing the energy on the earth to become different, which has led to the complete destruction of the cultivation civilization.

Of course, these are all Lu Yuan's speculations, but Lu Yuan feels that his speculation should be correct, and now it is just a lack of physical evidence.

Although there are not many people who believe in this now, and it is more likely to be rejected by the mainstream scientific community.

But he believes that with his exploration of the earth, all kinds of mysterious treasures on the earth will appear, and eventually people will believe all this.

From this day on, Lu Yuan finally truly found his purpose in life.

He is determined to spend the rest of his life exploring the Earth and searching for all kinds of lost civilizations and treasures around the world.

Before leaving the grotto, Lu Yuan handed over the two snow monsters to the team of scientists.

Scientists were once again shocked by the appearance of the snow monster.

There have been legends of snow monsters for a long time, and scientists have searched for them many times, but unfortunately without success.

Unexpectedly, Lu Yuan not only found the snow monsters, but also successfully tamed them.

After leaving the grotto, Lu Yuan returned to Yingzhou. There are some things that have to be sent back first.

When he saw the children of Nie Case again, the five children had completely changed.

All five children are now attending the newly built school in Yingzhou.

In order to keep the children up to speed in school, Anthony also hired tutors for several children.

After Lu Yuan returned to Yingzhou, he also officially adopted five children.

......

"Nie case, there are some things I want to hand over to you!" Lu Yuan said solemnly to Nie case.

Nie seemed to have expected something, and he nodded with tears in his eyes.

Lu Yuan sighed and handed over the urn and relics of Nie's parents to the child.

Nie took over his parents' relics, and his tears finally couldn't help falling.

Lu Yuan sighed and walked out.

After leaving Nie's case, Lu Yuan walked into Anthony's office.

Although Yingzhou is already a country of Pyu externally, there are no major changes internally.

It's just a change of the names of the departments.

Anthony's office has also not changed, but the name has been changed from the general manager's office to the general office.

"Boss, why are you here?"

Although Lu Yuan repeatedly refused this title, Anthony and the others still insisted on calling him so, and after a long time, Lu Yuan acquiesced.

"Anthony, this time I have obtained a batch of rare treasures in the Langar area, you arrange for someone to build a new museum as soon as possible, I plan to put these treasures in the museum, and also give ordinary people the opportunity to learn about prehistoric civilization. ”

"Your Excellency, you are so great, don't you know what else to ask for?"

"You can find some more people and make some videos of prehistoric civilizations, and make them once a month first. I think that in addition to the scientific community, ordinary people should also have the right to learn about prehistoric civilizations. ”

"Yes, as you wish!"

"By the way, the museum should be built as big as possible, and the security work must be done well, and there will be more treasures in the future!"

"Your Excellency, don't worry, our Yingzhou can now be said to be the safest place in the world. ”

Lu Yuan nodded, and what Anthony said was also good.

Yingzhou is far away from the rest of the world, and there are only a limited number of ways for outsiders to enter and leave Yingzhou.

Moreover, the armed forces on the island are also very strong, strictly speaking, the armed forces of Yingzhou are seriously excessive.

Speaking of which, although Yingzhou is small, there are actually very few countries that can really pose a threat to Yingzhou.

If it weren't for the agreement signed at that time, Yingzhou's reduction of half of its armed forces would have been enough to ensure its own security.

It is precisely because of such a strong armed force that Anthony has such self-confidence.

"Anthony, you're right, it's difficult for outsiders to invade our Yingzhou. But beware of the people inside!"

"Your Excellency, please rest assured, I will definitely strengthen internal discipline!"

"By the way, did you find out anything about my last attack?"

Anthony shook his head, "Not yet, but the intelligence department speculates that this organization should want to study Your Majesty's body!"

"Well, you're right, but the other party actually knows my whereabouts, I'm afraid this is revealed by our insiders......"

"Your Majesty, the people in the intelligence department think the same way now, but our intelligence department has only been in existence for three months, and most of them have little experience......"

Lu Yuan understood what Anthony meant.

"I understand that, Anthony, and I don't expect them to find out anything. ”

"Leaving things to them this time is just giving them a chance to exercise. ”

"I believe that since the people behind the scenes have made a move, there will definitely be a second time, and I will wait for them to make another move!"

"By the way, if you go on, the main focus of the intelligence department is still on collecting all kinds of treasures and prehistoric civilization materials. ”

"Okay, you're going to be the world's greatest explorer!"

Lu Yuan smiled noncommittally: "Everyone has their own pursuit, and my pursuit is to dig up the buried treasures in our world!"

"I believe that one day, our Yingzhou will become the place with the most treasures in the world!"

"Your Excellency, I'm sure you'll be able to do it!"

"Haha!"

Lu Yuan laughed loudly, "Anthony, I'll leave the rest to you, I need to go to the West Country next!"
