"The main body of the house has been found!"

An exclamation broke the immersion of the archaeological base of Sanxingdui No. 8 sacrificial pit.

Outdoors, Qin Zhan, a researcher at the Sichuan Institute of Archaeology, who led a group of uncles and aunts to explore archaeology, shouted in surprise.

In a rebuilt building area, he found a distinct trench made of pottery shards!

This trench is composed of pieces of pottery shards standing upright, which shows that this trench should have been a wall made of pottery shards!

This house should be regarded as a very elegant house in the era of Sanxingdui civilization.

A number of archaeologists from the Sichuan Institute gathered together to study the age of the house.

After careful discussion, everyone agreed that this house, which is only 20 meters away from the No. 8 sacrificial pit, should be at the same time as this sacrificial pit.

That is, both were built at the same time.

Now, the meaning of this house is different.

What is the purpose of the house built next to the sacrificial pit?

Obviously, it is definitely not the inhabitants who live, but the sacrificial buildings on the ground!

Sacrificial architecture, this kind of thing, has appeared as early as the earliest tribal times.

In the tribal era, when the ancient ancestors sacrificed to the gods and ancestors, they would build a high platform, and then build a sacrificial place, a fixed sacrificial platform.

This has been found in many Neolithic sites.

Later, it gradually evolved into a place like "ancestral hall" and "ancestral heir".

The mausoleum of the nobles, next to which there is also a supporting priestly building.

The archaeologists of the Sichuan Institute believe that this house, which is only 20 meters away from the K8 sacrificial pit, is a sacrificial building.

With this speculation in mind, they began an in-depth archaeological excavation of the building.

Soon, they found some stone tools in the remains of the house, which were clearly deliberately made.

Some of these stone tools look like chiseled animals, and there are incomplete stone congs, stone tigers, and stone axes......

Like these stone tools, in Sanxingdui, it should also be regarded as a kind of ritual weapon.

Because there are stone cong and stone axes, Cong is one of the six major ritual vessels first determined by Chinese civilization, and is widely distributed in various cultures at that time.

Therefore, these stone tools should have a lot to do with sacrifice!

This can be regarded as direct proof of the idea that these archaeologists guessed that this house was a sacrificial building!

On the other side, just as Pit No. 8 was boiling with the discovery of the sacrificial building.

Chen Han himself is not on the side of the Sanxingdui No. 8 Pit Archaeological Base, but in the Sanxingdui Cultural Protection Center!

He came here because he had one thing to be involved in.

As for the red spots found in the sacrificial pit, the Cultural Preservation Center has found a way to solve the mystery of its composition.

First of all, through the method of elimination, the staff of the Cultural Preservation Center have ruled out the possibility that these red spots are cinnabar.

This was determined experimentally.

Next, the staff conducted research around to prove whether these red spots were bloodstains.

In fact, this topic has been raised by scholars one after another since the 80s of the last century.

It's just that the technology at that time was not advanced enough, and there were really not so many artifacts with red spots found.

So it wasn't until this restart of Sanxingdui archaeology that it was mentioned again.

With the passage of 40 years, not only archaeological technology is advancing, but science and technology are also making great strides.

First of all, there are two special experimental methods.

One is the infrared spectroscopy experiment.

There happened to be infrared equipment at the Cultural Preservation Center, so the staff gave it a try.

However, the effect is mediocre.

It may be that the time of the sample is too long, 3,000 years ago, and there is not much left of the erythema component in such a long time.

By irradiation of infrared rays, it is no longer possible to find any valuable samples from above.

There is no way to tell if these erythema are related to blood.

The first experiment was soon declared a failure.

However, the staff also prepared a second experimental method.

It is also an emerging tool.

Speaking of which, this method is still inspired by forensic science.

A reagent called "luminol".

It is a technique that is widely used in forensics.

The usefulness is actually very simple.

For example, if there is a homicide scene, but the scene has already been cleaned by the murderer once, and the blood on the ground has been washed off with water.

So how do you find the remains of these bloodstains?

Just spray luminol.

This reagent, after a chemical reaction with traces left in the blood, glows blue.

The principle is that this reagent can detect the presence of iron ions in the blood and then bind to them.

No matter how much blood remains, even if there is only a trace of blood, then it will glow.

Now this reagent is widely used in homicide investigations.

In the past, murderers could clean up the crime scene with water after killing someone, at least to the point where it looked very clean to the naked eye.

But not anymore.

Because the blood cells in the blood are in "molecules".

No matter how you clean it, because the ground itself is uneven, even if it is a tile floor or wooden floor in a commercial house, there will still be some blood left.

As long as the luminol reagent is sprayed, as long as there is blood that has been sprayed on the ground, there will definitely be a blue light.

This method is very easy to use!

The only thing that worries the staff, though.

In the field of criminal investigation, luminol is now only used in the blood stains that have been used for decades at most, and has never been used in the blood traces of hundreds of years.

Not to mention three thousand years.

Whether this reagent can still work or not, all the staff have no idea in their hearts.

But this kind of thing, you have to try it to find out.

Science is about being brave enough to try.

The luminol medicine was not easy to handle, so I reported it to the head and waited a week for it to be delivered.

Chen Han also heard the news before he came to Sanxingdui Cultural Protection Center to watch.

By the time he arrived at the Cultural Preservation Center, he was halfway through the experiments.

The staff had used a cotton swab to extract some traces of red spots from the gold mask and placed the swab in pure water.

When Chen Han arrived, he happened to see a staff member wearing protective clothing and a mask, dropping luminol reagent into the test cup.

Seeing this scene, he hurriedly asked nervously, "How is it?" Is there a reaction? ”

Several staff members raised their cups, looked at them carefully, and shook their heads.

It doesn't seem to show any signs of blue light.

At this time, a staff member's eyes suddenly lit up, thought of something, turned his head and shouted: "Turn off the lights!" ”

"Smack"

The lights in the lab are turned off.

In the absence of an external light source, the laboratory instantly became pitch black, and the fingers could not be seen.

And at this time, a light blue light appeared in everyone's sight!

"It's lit!"
