In the secret vault, in addition to these creature bones, skulls, initiating magic weapons, and some spiritual herbs and elixirs, there are also some strange meteorites.

There are a lot of these meteorites, there are hundreds, the big ones are tens of thousands of catties, and the small ones are as big as fists, Yang Fan swept it and found that there were dozens of good refining materials in the middle of these meteorites.

However, he didn't lack weapons and magic weapons on his body now, so he skipped it after taking a look.

"What is this?...... Duliba Stone Saucer?"

On a shelf, Yang Fan saw a gray stone dish in the shape of a disc, about 30 centimeters wide, two fingers thick, and a small hole the size of an index finger in the middle.

Seeing that the label seemed to be written with the words 'Duliba Stone Plate', Yang Fan asked strangely.

Professor Lu was beside him, and then he said: "This is the Duliba stone dish, which was discovered by Qi Futai, a professor of archaeology at Jingcheng University, and his students in a cave in Bayan Kala Mountain, Qinghai Province in 38 years. It is said that when he discovered the caves, they were artificially carved into a system of tunnels and underground storage rooms, and the walls were square as if they had been lighted. ”

Professor Lu told the story of the discovery and origin of the Duliba stone saucer.

The discovery of the Duliba stone dish was indeed very fortuitous, when Professor Qi Futai and his students found these caves, and found some burial plots underneath, and these burial mounds were buried in the tombs of some kind of skeletons less than 1.4 meters tall, these skeletons had huge heads and thin bodies, and they thought they were some kind of mountain gorillas at the time.

There are no inscriptions in the tombs, but there are a number of these stone discs, each of which is engraved with two small grooves that twist from the edge of the disc to the hole in the center of the disc, like a Festo disc.

These discs and other discoveries were marked one by one, and some of them were brought back and stored at Kyungyo University for twenty years, during which time no attempts at decipherment were successful.

When the discs were examined in more detail in 1958 by Tsum Um Nui of Beijing, he concluded that each trench contained a series of unknown hieroglyphs.

The hieroglyphs were small enough to be read with a magnifying glass, many of them had been weathered, and when Dr. Tsum tried to decipher them, he discovered that they were referring to a crashed landing of a Duliba spaceship, and that most of the survivors had been killed by the locals.

According to Tsum Um Nui, one of the passages reads as follows:

"The Duliba people are from the clouds, sitting in flying machines. Our men, women and children hid in the cave ten times before the sun rose, and when they learned the language of the Duliba people, they learned that the new arrivals were coming with peaceful intentions."

"Tsum Um Nui" is not a true Chinese name, and some believe that the name may be fictional or a literal translation into Chinese.

No one in the world can completely decipher any kind of unfamiliar text, and Dr. Tsum is no different, no one in the world can translate Duliba at all. In addition, Dr. Tsum said that it was hieroglyphs, how do we know if it is hieroglyphs, even if it is hieroglyphs, but the problem arises again, even if he is pictographic, it is also pictographs on their planet, how does Dr. Tsum understand it?

Unless he is a Duliba, his words are not credible at all.

In 1965, Professor Qi Futai and four of his colleagues were finally allowed to explain their theory, which they published under the title "Etching of a spacecraft that landed on Earth 12,000 years ago, as described on a disc."

Later, Russian scientists also wanted to see these discs, so several of them were sent to Moscow for testing, and some scientists in Moscow wanted to play the stone disc by playing a record, and the machine made a huge roar when the stone disc rotated, and the scientists who did this experiment said that the reason why the machine roared was because the stone disc had the same properties as a record.

But unfortunately, after a few decades, some people wanted to find the stone dish certification research institute again, so they came to Huaguo to look for the stone saucer, but they found that there was no information on the stone saucer being lent and recovered in any records of Huaguo, and no one had ever seen the stone saucer again, and they also went to look for the cave, but the cave and the stone dish were gone.

One day, a reporter also published a picture of a stone dish of Duliba, but after investigation, it was proved that it was not the legendary stone plate, but an ordinary jade stone. So some people suspect that there is no stone dish at all, and everything is a lie.

The above are some of the online information that Shen Yueqing showed Yang Fan, and the warehouse keeper looked at it and said: "The Duliba stone dish does exist, don't we have one in front of us?" But it is also true that most of them have been lost, and there are a lot of things that were destroyed in the chaos back then. ”

Seeing that he shook his head when he spoke, with a look of pity, Yang Fan and Shen Yueqing didn't speak, only Professor Lu, Professor Liu, and Jing Aiguo's expressions fluctuated a little, and they thought of something.

Especially Jing Aiguo, all his encounters were because of that incident, almost his family was ruined, and when he heard it at this moment, he couldn't help but burst into tears.

"Professor Jing, things have already passed, just let it pass, people have to look forward. Professor Lu patted Jing Aiguo's shoulder, feeling a little empathetic.

"Well, thank you, Professor Lu, I understand. ”

Jing Aiguo wiped his eyes and put away all his sadness.

Seeing that his mood would not be good for a while, Professor Lu turned to the custodian and said, "Old Wu, by the way, I remember that there are two complete pieces of the Duliba stone dish, and what about the other one?"

Lao Wu said: "The other piece is being studied in the laboratory, do you want to go and see it?"

Hearing his words, Professor Lu first glanced at Yang Fan, and when he saw him nodding, he said to Lao Wu: "Go and see, is it Lao Fang who is researching?"

Professor Lu asked again, but Lao Wu only nodded and did not speak.

The six of them left the vault and soon went to a laboratory, which was also in the vault, and was specially built to study these strange things.

The laboratory is not big, but it is not small either, and it is divided into more than two dozen different research rooms, and along the way, there are people in white coats busy in each research room.

There are as few as three or two people, as many as seven or eight people, men and women, old and young.

There are also a variety of instruments, such as spectroscopy, electromagnetism, and exploration and scanning of internal structures, which can almost be used.

The research objects are also different, some scan the strange head, some repair the broken clay tablet, and some put a stone on the table and drip chemical reagents on it.

Yang Fan is not very interested in these things, what he is most curious about is the Du Liba stone saucer, this thing seems to be really unusual.

As for whether it was alien or not, he couldn't be sure, and the vault didn't have the bones of the Duliba people, so he couldn't guess what it was.

"Old Fang, are you still busy?"

After Lao Wu led them into a laboratory in the back, Professor Lu said to an old man in a white lab coat with gray hair and beard.

This old man is indeed not young, and it is estimated that he can be close to seventy or eighty years old.

It's just that although he is quite old and his face is full of age spots, his mental state is good, he has a pair of reading glasses on his face, and he has a very strong scholarly atmosphere.

"Old Lu, why are you here?"

Hearing Professor Lu's voice, Professor Fang immediately turned his face, and then said with some surprise.

"We have nothing to do but go to the Three Treasures Palace, I heard that you brought the Duliba stone dish to study, let's take a look. Professor Lu replied with a smile.

Professor Fang also had a smile on his face and said, "I heard that you didn't go to a secret base? ”

The professor of Nantianmen didn't know that he had been recruited by the state for a short time, and he used a lame excuse that he died by fire, so that he disappeared forever from the eyes of ordinary people.

In other words, coming here means staying here for the rest of your life until you die, and it is not even estimated that a tombstone will be engraved after death.

This is also for the sake of secrecy, Professor Fang is like this, Professor Lu, Professor Liu is actually the same, otherwise, they are not qualified to contact these at all.

Of course, experts and scholars like them all have great curiosity, and they don't care about what happens after death at all, as long as they can get in touch with these secrets, they can be at ease even when they die.

For example, people like Professor Fang and Professor Liu who are called up under various excuses also happen from time to time in other countries, and if you pay attention to it, you will find that a certain scientist or expert scholar has either an accident in the morning or a plane crash and disappeared in the evening.

The general meaning is that they will not appear again, and the meaning is as simple as that.

With the means of a country, as long as it wants to hide certain people and prevent them from appearing in the eyes of the world, it is never very difficult.

It's not an exaggeration to say that's easy.
