Mr. David gently rested his hand on the soft cloth, his head was covered with a gas mask, and he was wearing a white coat, which looked very strange.

Han Xuan also leaned over, he didn't think that this thing would carry unknown germs, because it was not a glacier that had been frozen for thousands of years, and there was no known virus that could survive in a sealed tomb for thousands of years.

And in those glaciers, there may indeed be super primitive viruses that can exterminate all human beings, and in the speculation of dinosaur extinction theory, some scientists believe that they died from some kind of large-scale epidemic virus.

Recently, scientists in the United States have discovered strains of viruses hidden in some glaciers that may cause the spread of the disease, and they have isolated the bacteria from rod-shaped bacteria in the ice of Greenland, which are about 500 to 5,500 years old.

People often like to use "Pandora's box" to describe a place that hides disasters, scourges, and threats, and as this news was reported, overnight, the world's glaciers and permafrost became new threats to mankind because they may have hidden ancient bacteria and viruses.

Looking down at the animal skin that wrapped the sword, the text on it seemed to be written with some kind of black paint, and in the short time it came into contact with the air, the color of the text quickly faded at a speed visible to the naked eye until it disappeared, due to the special material, the animal skin did not turn into ashes, and was quite well preserved.

When he found that the font color had disappeared, Mr. David calmly told Han Xuan: "Don't worry, with our existing technology, we can restore those words."

When I was X-rayed, I noticed something wrapped around the sword, and I was going to spray some special styling agent similar to hairspray to prevent it from coming into contact with the air, but now it seems to be in good shape.

Okay, please give way, I'm going to have to put it in that box and get the air out of it, and last year people found leather shoes made more than 5,600 years ago in a pit in the South Caucasus of Europe.

When it was first excavated, the leather shoes found in Armenia were still relatively soft, and when exposed to the air, the leather began to harden, and I don't want the same to happen to this ancient animal skin......"

Han Xuan avoided hearing this, he had heard the news of the discovery of ancient leather shoes in Armenia, which was the earliest known area in the world to wear leather shoes.

Unlike other peoples, who are simply wrapped in animal skins, Armenian leather shoes have four sets of eyelets at the back, which are fastened together at the ends by using a strap through the eyelets, and fifteen sets of eyelets at the front, which are also tied from head to tail, similar to modern shoes.

After receiving the news, ZARA company even decisively came out with the same model, called it "retro", which is now very popular in the market, and is named Armenian shoes.

The media ridiculed him that after LV, Gucci, Chanel and other big-name companies, even ancient humans thousands of years ago were poisoned by plagiarism kings......

The excavated artifacts face many difficulties, the most difficult of which is to keep them in their original appearance when they were first unearthed, and few people know that the clay figurines in the terracotta warriors and horses are supposed to be colorful.

Unfortunately, the paintings are so difficult to keep, they oxidize within fifteen seconds after they come into contact with the air, dehydrate and curl within four minutes, and then quickly peel off and turn into dust, and then become the miserable appearance that later generations will see.

According to previous speculations, the sword still wrapped in animal skin was made of some kind of animal bone, which should not be afraid of air erosion, but the hilt of the sword was made of copper, and the exposed corner of the hilt had intricate patterns, which did not look like ordinary goods.

Mr. David, the chief restorer, is very experienced, from the time he opened the stone box to now, only a few tens of seconds have passed, he has put them together into the transparent glass cabinet next to them, and after quickly sealing them, he turned on the instrument switch, only to see the value of the internal air displayed on the LCD instrument, which was quickly reduced to a number close to vacuum.

The two things were safe for the time being, David lifted the gas mask, and he said: "It should be no problem, I didn't find anything that may be dangerous, the bronze tripod was not damaged when it was first unearthed, but it also showed a certain degree of oxidation after half a year."

This oxidation mark could not be repaired, and it was only after applying a special layer of paint that the spread was stopped, but fortunately the damage was not serious.

Now, let's get started, little boss, would you like to open that layer of animal skin with your own hands? ”

Han Xuan was naturally willing, the glass box in front of him was similar to the incubator that poured into the biological laboratory to cultivate special viruses, with two special rubber gloves on one side, and his hand could reach into it and operate through the gloves.

The heating was on in the room, the temperature was not too low, and the constant temperature was conducive to the preservation of the artifacts, and he replied: "Haha, that's great, just let me come." ”

David didn't tell him to be careful, the contents of the box, including this research institute, belonged to Han Xuan's private property, he could do whatever he wanted, and if he talked too much, it would be annoying.

Han Xuan took off his down jacket, which was a gray sweater of alpaca cashmere, rolled up his sleeves, he put his hand into the rubber gloves, and then began to open the layer of animal skin that rolled up the sword, the animal skin was still soft after a short time of contact with the air.

The bronze of the hilt is also shiny, not rusty, which is very rare, and in addition to the historical canon, this is the second well-preserved bronze that has been handed down from distant times.

The movements of his hands were gentle and slow, and as the animal skin that wrapped the long sword became less and less, the ancient sword with a long history, the true appearance gradually appeared in front of Han Xuan's eyes, surrounded by a circle of people, bodyguards and Olivia, the old Ernner butler and others were also there, their eyes changed from full of anticipation to disappointment, because of its shape...... It's really mundane.

The willow leaf shape of the sword body, the hilt is made of bronze, the color of the sword surface is white, compared to the bone mentioned before, it is more like it is made of stone, and there are some strange patterns carved on it, there are people, animals, houses, and the sun, ordinary, and the scene in the previous imagination forms a huge gap.

This was also beyond Han Xuan's expectations, when he saw the pattern on the sword body similar to the oracle bone inscription, his whole expression was stunned, his head was confused, and suddenly a thought popped up.

Thinking about it carefully, I was terrified, and I secretly wondered if this thing was ......
