The next morning, the Laboratory of the Academy of Astronomy.

Yuan Shichen carefully took out the ore that had been brought from home and changed his life trajectory.

Except for being a little cold and heavier than ordinary stones, the ore still looks ordinary and inconspicuous.

After some observation, Yuan Shichen first used instruments to calculate the density of the stones.

After measurement, the density of the ore is 7 grams per cubic centimeter, which Yuan Shichen is very sensitive to this density.

The density of ordinary rocks on the earth is generally 2.5-3.0 grams/cubic centimeter, while the density range of metal ores is 4-6 grams/cubic centimeter.

Most meteorites are composed of heavy minerals, so the density is 3-8 grams per cubic centimeter.

This means that if this ore was not artificially manufactured, it would most likely come from outer space!

Because it has no melting shell, Yuan Shichen did not consider meteorites before.

Thinking about it now, maybe it was because it had been too long on Earth that the melted shell had oxidized.

After reaching this conclusion, Yuan Shichen tried to peel off part of the ore.

Such a working procedure is already very proficient in recent meteorite detection work.

Generally speaking, he would first use an angle grinder to grind a corner of the stone, then observe the internal material of the stone, and then take down more representative parts as samples for analysis.

If you accidentally encounter a large difference in the surface and internal material structures, the treatment method will be much more complicated.

In the past, when cutting meteorites, it would take a little time to encounter iron meteorites. So Yuan Shichen originally thought that it would take a little effort to cut the ore into a corner.

............

More than an hour passed, and as time went by, he became more and more broken.

After more than an hour of grinding and cutting, the ore was completely damaged!

Apart from splashing Mars, the angle grinder replaced several ultra-high hardness saw blades, nothing else was found.

Yuan Naichen stopped cutting and picked up the ore and put it under his nose, but he still found no damage on the surface of the ore.

What is even more surprising is that after two hours of polishing, the ore still feels cold.

If it is another stone, after two hours of cutting, it is estimated that the heat generated by friction can be fryed the eggs.

Yuan Shichen fell into deep thought, and his mind rolled rapidly, trying to find what he knew was suitable for the conditions.

Half an hour passed, and he could only sigh, obviously this question had exceeded his cognitive scope.

"Sure enough, this stone is not an ordinary thing." Yuan Shichen sighed in his heart.

After some thought, Yuan Shichen decided to put the stone first.

He is planning to search for relevant information first while looking for more effective detection methods, and then further research after the conditions are ripe.

However, this time, there was not a loss. Yuan Shichen judged that this strange stone was most likely from outer space and had arrived at the earth for quite a long time.

While thinking about it, footsteps came from the laboratory next door.

"Xian Chen, you are doing decoration. The machine rang all morning." Liu Kun said with a smile after his head popping out of the door.

"No, I'm cutting a stone, it's super hard!" Yuan Shichen explained.

"Oh, it's the very hard meteorite sample you mentioned at the regular meeting a few days ago?" Liu Kun asked excitedly.

"Yeah, that's it." Yuan Shichen said after pausing.

"Do it well, Dean Li seems to attach great importance to this meteorite. Maybe he can make a big deal out." After Liu Kun said that, he turned around and returned to his laboratory to continue his busy schedule.

What Yuan Shichen and Liu Kun just talked about was certainly not the strange ore they had discovered before.

Last week, Yuan Shichen discovered an unusual guy while conducting meteorite testing!

Its melted shell appears in the color of black treasure green, with a very high hardness, and it also took a lot of effort to cut it open.

Through component detection, Yuan Shichen determined that it neither belonged to the Martian belt nor came from the moon.

After several comparisons, I can't figure out which planet it comes from.

It is very likely that it is a planet produced during the Big Bang period from outer space for more than 15 billion light years, which is very helpful for studying the formation of the universe.

Li Huiqun was also very interested after hearing about this at the weekly meeting. He said that the research value of this meteorite is extremely valuable, so he asked him to do further analysis and learn more about the sampling location. If necessary, he can go to the on-site survey.

............

After some twists and turns, Yuan Shichen learned that this unusual meteorite came from Xinjiang.

Unlike other meteorites found, this meteorite was discovered by a villager from Minfeng County, Hotan, in an ancient ruin in the Taklamakan Desert about 150 kilometers north of the county town.

Yuan Shichen checked relevant information and showed that this location was the ruins of the ancient city of Niya, known as the "Pompey City" in the East.

The ancient city of Nya was first discovered by the British Stein in 1901.

Stein collected a large number of Han Dynasty documents, pottery and wood carvings, coins and other precious cultural relics here, which caused a sensation in the entire archaeological world.

However, until the 1930s, people could not accurately determine the exact origin of this ancient site.

It was not until later that several Han bamboo slips discovered here traced back to a period of history in the Eastern Han Dynasty.

In order to fight against the Xiongnu's stable Western Regions, the famous general Ban Chao led his entourage to station in the Western Regions for decades.

He joined forces with 36 countries in the Western Regions to fight against the invasion of the Huns. He had been in power for decades and left behind the eternal legend of "sending his pen to join the army".

And this site that has been forgotten in the vast yellow sand is one of the 36 countries in the Western Regions in the past.

Yuan Shichen's intuition told him that the discovery method of this meteorite was unusual. Only by conducting on-site investigation and detailed understanding of the source of the meteorite can the deeper value of this meteorite be excavated.

After telling Li Huiqun about his initial thoughts, President Li also agreed with his point of view and agreed to go to the field for inspection, and planned to apply for special funds to form a scientific examination team.
