Early the next morning, the laboratory of the Faculty of Astronomy.

Yuan Haochen carefully took out the piece of ore that he had brought from home and changed the trajectory of his life.

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

After some observation, Yuan Haochen first used an instrument to measure the density of the stones.

The density of the ore has been determined to be 7 grams per cubic centimeter, and Yuan Chen is very sensitive to this density.

The density of ordinary rocks on Earth is generally 2.5-3.0 g/cm3, while the density of metal ores ranges from 4-6 g/cm3.

Most meteorites are composed of heavy minerals, so the density is 3-8 g/cm3.

This means that if the ore is not artificially made, it is likely to have come from outer space!

Because it did not have a molten shell, Yuan Haochen did not consider meteorites before.

Now that I think about it, maybe it has been on the earth for too long, and the molten crust has oxidized.

After coming to this conclusion, Yuan Haochen tried to peel off some of the ore.

This kind of working procedure Yuan Haochen has been very proficient in the recent meteorite detection work.

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

If you happen to encounter a large difference in the structure of the surface and the internal material, the treatment method will be much more complicated.

In the past, when grinding meteorites, it took a little time only when encountering iron meteorites. So Yuan Haochen originally thought that he could cut a corner of this ore with a little effort

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

After more than an hour of grinding, the ore was undamaged!

Except for the splash of sparks, the angle grinder replaced a few ultra-hard saw blades, nothing else was found.

Yuan Haochen stopped cutting, picked up the ore and almost put it under his nose, but still didn't find the slightest damage to the surface of the ore.

What's even more surprising is that after two hours of grinding, the ore is still cold to the touch.

If it is another stone, after two hours of cutting, it is estimated that the heat generated by the friction can be used to fry the egg.

Yuan Haochen fell into deep thought, his mind tumbling rapidly, trying to find the substance that he knew was eligible.

Half an hour passed, and he could only sigh, obviously the question was beyond his knowledge.

"Sure enough, this stone is not a mortal thing." Yuan Haochen sighed secretly in his heart.

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

He plans to search for more effective testing methods while researching relevant information first, and then conduct further research when the conditions are ripe.

However, this time it was not without harvest, Yuan Haochen judged that this strange stone was very likely to come from outer space, and the time to reach the earth was quite long.

Just as he was thinking about it, there was the sound of footsteps in the lab next door.

"Hao Chen, you're doing decoration, the machine rang all morning." Liu Kun popped his head out of the door and said with a grin.

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

"Oh, the very hard meteorite sample you talked about at the regular meeting the other day?" Liu Kun asked with interest.

"Well~ yes, that's it." Yuan Haochen said after a pause.

"Do it well, Dean Li seems to attach great importance to this meteorite, maybe he can break the news." After Liu Kun finished speaking, he turned around and went back to his laboratory to continue to be busy.

What Yuan Haochen and Liu Kun were talking about just now was, of course, not the strange ore they had discovered before.

Last week, when Yuan Haochen was conducting a meteorite test, he found an unusual guy!

Its molten shell has a black and green color, and its hardness is very high, and it also took a lot of effort to cut it.

Through composition testing, Yuan determined that it was neither a meteorite from the Martian belt nor from the moon.

After several comparisons, it is impossible to figure out which planet it came from.

It is highly likely that it was created from outer space at the time of the Big Bang, more than 15 billion light-years away, which is very useful for studying the formation of the universe.

In this regard, Li Huiqun was also very interested after hearing about it at the weekly meeting, and said that the research value of this meteorite is extremely high, and asked him to do further analysis, and learn more about the sampling site, and if necessary, he can go to the field to investigate

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

Unlike other meteorite discoveries, this meteorite was discovered by a villager from Minfeng County, Hotian, at an ancient site in the Taklamakan Desert, about 150 kilometers from the county seat.

Yuan Haochen consulted relevant information and found that this location was the ruins of the ancient city of Niya, which was known as the "Pompeii City" in the East.

The ancient city of Niya was first discovered by the Englishman Stein in 1901.

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

However, until the 30s of the last century, people could not accurately determine the exact origin of this ancient site.

It was not until later that several Han Janes were discovered here, which traced back to a period of history in the Eastern Han Dynasty.

In order to fight against the Xiongnu and stabilize the Western Regions, the famous general Ban Chao once led his entourage to be stationed in the Western Regions for decades.

He united the 36 countries of the Western Regions at that time to resist the invasion of the Xiongnu, and weizhen the Western Regions for decades, leaving behind the eternal story of "throwing pen from Rong".

And this ruin, which was forgotten in the vast yellow sand, was one of the thirty-six countries of the Western Regions in the past.

Hara's intuition told him that the meteorite had been discovered in an unusual way. Only through field investigation and a detailed understanding of the origin of the meteorite can the deeper value of this meteorite be unearthed.

After telling Li Huiqun his initial thoughts, Dean Li also agreed with his point of view, agreed that he would go to the field for an investigation, and planned to apply for special funds to form a scientific research team.

In addition, the research team also plans to invite an archaeological research team from Tsinghua University to assist in the work.
