A week later, Beijing, School of Astronomy, Tsinghua University.

After a long journey, the Flying Stone finally arrived at the laboratory of the School of Astronomy.

Due to the large volume and mass, Li Huiqun deliberately converted a large equipment room on the first floor of the laboratory building into a laboratory, which was specially used for the storage and research of [Flying Stones].

"Hao Chen, this time has been hard, and I have tanned a lot in the desert." Li Huiqun looked at Yuan Haochen kindly and said.

"Dean, this is what I should do, and this is what I am particularly willing to do." Hara replied, his love for astronomical research revealed between his words.

Li Huiqun didn't say anything, just nodded with satisfaction.

At this time, the [Flying Stone] has been professionally cleaned, removing the dust that covers thousands of years, showing its true nature.

"Ordered by the sky, both longevity and eternal prosperity" eight stone carved Chinese characters, literally the original gold lacquer mounting has been basically oxidized and peeled off, only a few traces remain.

After measurement, the overall volume of [Flying Stones] is about 3 cubic meters, and the mass is more than 9 tons, which is the largest stony meteorite found so far.

Most of the surface of the Flying Stone is dark brown, with air marks of different sizes.

The corner of the flying stone has obvious traces of being chiseled and then polished.

According to the information in the previous dream, Yuan Haochen guessed that the missing part was the black treasure green meteorite sample that was chiseled off by General Ban Chao's axe, and then tossed and turned several times, and finally fell to the experimental group.

In this way, the composition of this whole meteorite is not single, except for the missing corner is a black treasure green meteorite texture, most of the others are composed of other components.

With such a complex meteorite, Dean Li Huiqun was amazed and said that it was the first time he had encountered it.

What kind of secrets are hidden in it, all the mysteries need to be further studied to unravel

In the next week, Yuan Haochen was completely immersed in the study of [Flying Stones from the Sky], except for basic rest, most of the rest of the time was soaked in the laboratory.

During this period, the news that the meteorite scientific research team led by Yuan Haochen had made a major discovery in Xinjiang once again shocked the entire Tsinghua University.

Yuan Haochen kept a low profile as always, and in addition to talking to his parents on the phone about his special experience in the ruins of Niya and the ancient city of Loulan, he only mentioned it slightly under the inquiries of Zhang Xiaoming, Yang Yang and Deng Xiaochao.

This is the sixth day that Yuan has returned to the School of Astronomy.

Tsinghua University, School of Astronomy open-air stadium, in a simple circular audience, Yuan Haochen and Chen Shuqin are sitting side by side.

Because only satellite phones can communicate with the outside world in the depths of the desert, the two have been unable to contact each other for more than 20 days.

"I haven't seen you for more than 20 days, why are you so dark." Chen Shuqin looked at Yuan Haochen's slightly dark face and said with a smile.

"It's not going to support the construction of the desert." Yuan Haochen quipped.

"Your discovery in Loulan this time is a sensation, and even our school is spreading your adventure experience in the ruins of Niya and the ancient city of Loulan." Chen Shuqin said with great interest, "There are rumors that you are in danger in the sandstorm, and there are also rumors that you can sense the underground stone chamber through the power of the stars, and the rumors are vivid." “

Yuan Haochen smiled and said nothing, these episodes must have been "leaked" by Lu Qinglian and Chen Xi, and they have undergone careful artistic processing.

"Fortunately, you are all safe, I am really worried about you when I heard the sandstorm" Chen Shuqin said softly, but her eyes looked at the runway not far away.

"Thank you for your concern." Yuan Haochen turned his head to look at Chen Shuqin beside him, and his heart was filled with a trace of warmth.

"Do you want to be busy researching next?" Chen Shuqin asked again.

"Well, the meteorite has been found, and it will take a lot of time to uncover the secrets of the meteorite." Yuan Haochen replied.

"Pay attention to your body, don't work too hard." Chen Shuqin's words were full of concern.

"I'll pay attention, by the way, how are you doing?"

"I'm doing well, my studies are going well, and I recently took my second major. Seeing you so diligent, I'm embarrassed to be lazy. Chen Shuqin replied with a smile.

"Oh, what did you choose for your second major?" Yuan Haochen asked.

"Biology."

"From international finance to biology, it's a big span."

"You can only be allowed to engage in scientific research. My dream in kindergarten was to be a scientist. ”

"Haha, nine out of ten children are quite scientists."

School of Astronomy, Tsinghua University, Laboratory Building, Dean Li Hui's Experimental Group Weekly Meeting.

"Dean Li, the preliminary test results of the meteorite brought back from the ancient city of Loulan have come out." Yuan Haochen reported. "Did you make any special discoveries?" Dean Li asked solemnly.

"Now it can be basically concluded that the black treasure green meteorite sample in our laboratory is a part of this [Flying Stone], and the connection between the two stones is basically consistent." Yuan continued, "In addition, we also found two parts of the overall meteorite with the same material as the black treasure green meteorite sample. They are located at the bottom of the [Flying Stone], and there is also an inlay inside. ”

"Have you analyzed the composition of each part?" Dean Li continued to ask.

"After testing, the facet of the black treasure green meteorite is as bright as pure iron. It is characterized by a pronounced molten crust, as if the rock contains a layer of black-green mud on the outside, and is highly magnetic. The black green meteorite sample contains 56% magnetite, 7% nickel, and the rest is non-terrestrial minerals. As we have previously concluded, the astronomical community has not yet been able to determine its source compared to the various meteorite samples found around the world, and it is very likely that it came from a planet created during the Big Bang 15 billion light-years away. ”

"However, the composition of the other parts of the [Flying Stone] is completely different from the part of the Black Treasure Green Meteorite." Yuan Haochen continued. "The rest of the meteorite composition contains about 90% dark brown metroptite, 5% monoclinic pyroxene, and 1.7% plagioclase."

"Whether there is a comparative analysis with other meteorite sample components." Li Huiqun asked when he heard this.

"After control, the sample composition of this part is basically the same as that of many [pure olivilinear Martian meteorites] found in history." Yuan Haochen replied affirmatively.

"Martian meteorites!" This conclusion surprised everyone in the experimental group.

After the meeting, Dean Li and Yuan Haochen took samples and analyzed the [Flying Stones] again in the laboratory.

The results of the re-analysis once again confirmed Yuan's previous conclusions.

"Hao Chen, what do you think of this meteorite?" Dean Li looked at Yuan Haochen and asked meaningfully.

"Dean, because the composition analysis and source of the main part of the meteorite and the black treasure green part are obviously not consistent. My guess is that the first is that an asteroid from space hit the Martian volcanic rock formation, and the violent impact caused part of the Martian lava to splatter and escape the gravitational pull of Mars. A part of the Martian lava fused with the fragments of the asteroid during the impact, and finally changed its trajectory for various reasons and entered the gravitational range of the Earth, and finally fell to the Earth to become the [Flying Stone] we see now. Yuan Haochen replied seriously after thinking about it. Chen, your assumptions are very imaginative and full of rigorous logic, and I agree with your assumptions. Dean Li said with great emotion, "In the current situation, our research strength is no longer enough. I will report our research results to the Chinese Academy of Sciences as soon as possible, and invite more experts and scholars to participate in this project. “
