When the blindfold was found, everything went smoothly and naturally.

In addition to Yu Han, the last two of the Jade Nine Apertures, that is, the jade earbuds, were also quickly found by Chen Han.

It is two cylindrical jade objects with a diameter of half a centimeter and a length of two or three centimeters.

Well, this time it's really purpose-built.

Because in addition to being used to plug ears, it is difficult for other jade objects to be so small.

This also broke the situation that Liu He's jade nine tricks were all "second-hand".

Magical, magical.

Why did Liu He use so many utensils that he had used to play with in his lifetime and use them as jade nine tricks.

And why did you choose to use a specially made jade plug when you go to the earbuds?

Since you can use agate beads for plugging your nose, you can actually use agate beads for your ears.

Why didn't you continue to use agate beads?

I can't find the answer to this puzzle.

Archaeological excavations are like this, in the process of excavation, although some historical fog will be constantly revealed, but there will still be many new puzzles.

The more you know, the more you are confused.

It's not just science.

The same is true of archaeology.

Some things are destined to be unanswered.

Unless humans possess time-traveling machines that can go back to the days when the Marquis was alive and ask him personally, these mysteries may be solved.

......

After waiting for many days.

Physical anthropology experts from the capital finally arrived in Nanchang and arrived at the laboratory of the archaeological base of the Tomb of the Marquis of Haiding.

Because they had been waiting for the experts of physical anthropology, before the experts arrived, all the archaeologists did not move the upper and lower jaws of the Marquis of Haidu.

To be precise, it didn't open the mouth of the Marquis of Haidu.

Therefore, Yuhan has not had a chance to extract it for the time being.

Now that the physical anthropologists are in place, everyone can finally clean and excavate the teeth of the Marquis of Haidu.

It was still two floating planks built on top of the coffin.

The two experts in physical anthropology, as well as Kong Jianwen and Chen Han, were all lying on the wooden plank, their heads facing the coffin.

One of the experts, Professor Zhao, held a small shovel and carefully cleaned Liu He's upper row of teeth.

"Look at the state of preservation, it's rare!"

"Anyway, you can see that you eat well." Professor Zhao said with a smile.

Nothing else has been seen yet, but at least it is obvious that Liu He's teeth can see that he ate very well before his death.

In fact, this does not need to be confirmed by the grinding marks of the teeth.

People are people who have been princes and kings and emperors.

It belongs to the top handful of nobles.

Even in the Western Han Dynasty BC, the food was certainly not bad, not to mention balanced nutrition, but high-protein foods were definitely not less.

However, after a little judgment, Professor Zhao said, "But although he eats well, he may not absorb it."

"The owner of the tomb should have gastrointestinal problems, and often have diarrhea, or have bugs in his stomach."

"I'm more inclined to have bugs in my stomach, Jiangxi belongs to the southern region in the Western Han Dynasty, next to Hunan and Hubei, and it is estimated that there are also parasites rampant."

Chen Han listened to Professor Zhao's inference in great surprise, and exclaimed in his heart.

With just two rows of teeth, it can be seen that Liu He had digestive problems before his death, food was not absorbed, and he also had gastrointestinal problems and frequent diarrhea?

What kind of operation is this??

I know it's science, but to be honest, it looks even more outrageous than metaphysics...

And that's not all.

Professor Zhao added, "Liu He should not have been in good health when he was one or two years old, that is, before weaning."

This time, Kong Jianwen was also surprised, nodded and agreed, "According to historical records, Liu He is indeed much weaker

I was in poor health when I was a child, and I was bedridden all year round when I became an adult, and I may have spondylosis."

Professor Zhao nodded understandingly: "Whether you have spondylosis or not, you can't tell it with your teeth."

"But it's probably right to be frail and sickly, and it's been a bad health since childhood."

After a brief tooth cleaning, the two professors decided to go in for extraction.

However, in order to prevent secondary contamination, it is necessary to wear a full set of sterile gowns.

Hair is wrapped in sterile bags, masks, gloves, and sterilized lab coats.

After they were all dressed neatly, the two of them took the two students and lay on the operating board again, ready to extract the teeth.

"Come, take a look at this tooth, it's pretty worn."

"You can see it from the layered shape of the enamel development."

"This deceased must be in his late thirties, or in his early forties."

The two professors cleaned up while giving practical lessons to the two students.

It's just that the age of the tomb owner is calculated according to the degree of tooth wear, but it is not quite right.

According to historical records, Liu He, an unlucky bastard, died at the age of 33, far from being behind the age of thirty and in his early forties?

However, frowning, Kong Jianwen didn't say this, just stood quietly aside, watching several experts busy.

Chen Han, who was originally going to ask out loud, swallowed the words that he was about to blurt out when he saw this.

The two experts were still exchanging various "professional terms" with the students, and Kong Jianwen and Chen Han were stunned when they heard it.

As the saying goes, insiders look at the doorway, and laymen look at the liveliness.

It's the same as when everyone else looks at them archaeologists.

When Chen Han and the others were watching the exchange and discussion among physical anthropology experts, they were just watching a lively discussion.

However, from their words, the two still extracted some key points.

Like what.

After hearing several experts frequently mention the importance of "tooth roots", Kong Jianwen interjected and asked, "So, if there is a tooth root now, is it considered a big discovery?"

"Yes!" One of Professor Zhao's students raised his hand and patiently explained, "As long as there is a tooth root, then at least DNA testing can be done."

"The crown of a tooth cannot be used for DNA identification, only the pulp in the root of the tooth can be extracted for DNA identification."

Kong Jianwen nodded knowingly: "The root of the tooth is a necessary condition for making DNA, right?"

"Yes, that's right!"

Several experts cleaned up quickly, and some of the teeth that were still hidden in the mud were also cleaned out.

After careful comparison and discussion, they quickly decided to extract a back molar!

On the one hand, the posterior molars are the strongest, and on the other hand, they are the most well-preserved.

A posterior molar tooth is carefully pulled out of the "gum" in the mud and placed in a small plastic box.

Professor Zhao patiently explained, "There are many things that can be done with teeth."

"For example, the structure of the food, the migration of the tomb owner during his lifetime, and his genetic structure."

"If we can do DNA, we can study the kinship and genetic connection between him and other Han people with the same surname, as well as between modern people with the surname Liu."

"In particular, the Liu clan in the Han Dynasty was the most serious spread of the royal family in the past dynasties, and the study of the Liu family's genes is of great significance to the genetic system of modern humans!"
