Lin Fan quickly found the corresponding place. He didn't mess around, nor did he use the sixteen-character Yin-Yang Feng Shui secret technique to find the dragon's acupoints, but relied on instruments!

This instrument is actually ultrasonic, which is different from the life detector because it is used to detect cavities.

Soon, Lin Fan found the cavity below and took out a small machine!

The Chinese industry in the 1980s was still developing, but some basics were still lacking, such as exhaust fans!

This stuff isn’t difficult!

Lin Fan started to toss on the ground carefully, then slowly found a weak spot and started cleaning it.

Fortunately, there are no so-called protective techniques in tomb robbers. Below, there is actually a sacrificial relic, not a tomb, so there are not so many mechanisms and the like. But because it has been deposited for thousands of years, who knows the gas below will have

What is it!

Therefore, these gases must also be collected.

In addition, you have to be careful not to let oxygen in!

Therefore, a layer of plastic sheet appears directly, just like a leather spatula, covering the entire hole first, and then a machine directly pokes it in, puts it down, and then starts to pump the air crazily.

The air inside was quickly pumped out, and actually mixed a lot of it, but with the pumping, the oxygen at the entrance couldn't easily enter.

"water pipe!"

Lin Fan shouted loudly, and then he directly brought a water pipe over. The head of the water pipe was an atomizer. As soon as he opened it, countless antioxidant sprays were sprayed out. Then Lin Fan directly put the can inside.

.

It's a pity that with current technology, there is no small camera that can be drilled underneath using a rope to see clearly what's going on underneath.

There is also a large amount of antioxidant spray being pumped out, but it doesn't matter, because the amount is large and the pressure is high, it can be sprayed evenly on the surface of the object.

An hour later, the antioxidant spraying was completed!

However, it still needs to be dispersed, and there is a good way at this time, which is to throw dry ice into it!

Quickly lower the temperature inside, allowing the antioxidants inside to quickly form a protective film!

Then, it’s just waiting!

Wait a minute?

No, wait until daytime tomorrow, it is already night!

It's not because of any rules, but at night, when the temperature drops, the situation inside will change. It's not that there are any things like rice dumplings. Archaeologists will encounter some things that are difficult to explain, but in the end they will gradually

It was explained clearly using scientific means.

In the blink of an eye, it was the next day. Lin Fan and others took a deep breath. In this era, there was no such thing as air testing, so Lin Fan just threw a group of sparrows down!

What?

Sparrow is an animal with three kinds of existence?

Yes, that was when Lin Fan traveled through time. The sparrow now is still one of the four pests!

When the sparrows arrived below, they flew around in panic. Lin Fan would spray things down from time to time, which made the sparrows even more panicked, so they kept flying around.

Ten minutes later, Lin Fan nodded to everyone!

"dig!"

A group of people quickly started digging. The raincloth on top was also removed because it was no longer necessary. The antioxidant molecular layer below was also finalized, so you can breathe fresh air directly!

As soon as it was opened, countless air rushed into it. In fact, there was a lot of air in the first place. After it was drained, because of the presence of the raincloth, not much air got in, but it definitely got in. Any equipment

It cannot be absolutely sealed in such an environment.

The hole is being excavated larger and larger, because the flow of air is mainly a pipe.

"Next time, I will research a cement or soft glue that dries quickly. It should have strong viscosity and stick directly to the entrance of the hole. Then insert a stick into it, so that the sealing effect can be achieved!"

Lin Fan's idea was to block the entrance of the cave with something similar to plasticine, and put a pipe in the middle. The entrance of the pipe into the cave was open, but the part outside was closed!

Then there is an exhaust fan in the middle, which can quickly pull out all the air inside.

"It's a good idea, but it's a pity that we don't have enough research funds. And the most important thing is that many ancient tombs have been destroyed by our general rescue excavation!"

Many people say, if you do archeology, aren't you just legal tomb robbers with certificates?

of course not!

First of all, our country has made it clear a long time ago that no cemeteries and ancient tombs will be opened unless rescue is necessary.

The reason is very simple. When archaeologists in our country went to excavate an imperial tomb, as soon as they opened the door, within three minutes, countless precious cultural relics were oxidized!

Those books, silks and the like were directly turned into ashes. The whole country, even the bosses, were extremely sad!

Finally, the boss made a direct statement, saying that unless it was for rescue or necessary reasons, no more ancient tombs would be allowed to be opened.

So, the tone was set.

Then, the country will no longer take the initiative to excavate ancient tombs. Any country that does not nod is considered tomb robbing!

However, tomb robbers will not tell you this. For the sake of profit, many tomb robbers continue to destroy ancient tombs. Of course, with the advent of the era of large-scale infrastructure construction, more and more ancient tombs have been excavated by the country.

Do you really think it was the state that made the first move?

Go and see how many ancient tombs can be found in Chang'an City throughout the year!

These ancient tombs were not only owned by royal relatives, but also by many ordinary people. Some businessmen, or people with a little status, would build a tomb for themselves.

How many ancient tombs have been discovered in Chang'an City?

It’s hard to say, too many to count!

Anyway, for the ancient tombs, building a subway is something that is “don’t even think about it”.

What does that mean?

Anyway, as long as Chang'an City builds a subway, ancient tombs will definitely be dug.

But you say, is this called active discovery?

Of course not, it was an accident!

Therefore, the country had to be excavated in a salvage manner. One was to ensure that the contents inside would not be taken away, and the other was to ensure that the ancestors inside were not disturbed.

First of all, when the state is conducting rescue and excavation, it will first remove the owner of the tomb and send it to the cemetery. After burial, it will then start rescue and excavation. After finding clues about the owner of the tomb, it will make a monument for the owner of the tomb!

Then someone said that this tomb belongs to my ancestors!

Did the country take away the things?

of course not!

First of all, you have to prove that this is indeed a direct ancestor of your family!

What concept?

That is, you must have an ancestral genealogy to prove that this person is your ancestor, and it must be a direct line, so that once the ancient tomb is excavated, everything in it will belong to you!

If no one proves it, then it belongs to the country.

The state stipulates that everything under the ground belongs to the state.

Therefore, tomb robbing is illegal, and if you find agarwood or the like buried underground, it also belongs to the country. 500 yuan and a banner are the best destination...

And many people say that 500 yuan and a pennant mean that as long as you have antiques in your home, the country will forcibly collect them. No matter if you have hundreds of millions or billions of things, the country will only give you 500 yuan and a pennant in the end!

As mentioned before, first of all, if it is a regular operation, the state will not do this, because it is also illegal. If your things are regular, the state has no right to force recruitment.

Therefore, if you have antiques, they will be taken away and you will be compensated with 500 yuan and a banner. This is fake!

This is true only if you discover something that belongs to the country, hand it over to the country, and the country will give you a reward of 500 yuan and a banner.

Therefore, if you can prove that the ancestor belongs to your family, then everything belongs to you!

There is another exception, and that is meteorites!

Although the airspace belongs to the country, the meteorite does not belong to the country because it comes from outer space, but...

Be careful, but it’s coming!

If this meteorite has fallen on this planet for a long time, it belongs to the country.

In other words, if a fresh meteorite falls at your home, it is yours, first come, first served!

If it fell to the ground hundreds of years ago, it belongs to the country.

Of course, if you pick it up like meteorite and it falls in a desert or some other place, the country won't want it because it has no research value.

And if the meteorite that falls on your house is a special meteorite, the state will take it away for research, but will give you a compensation, but it will definitely be more than 500 yuan, and of course there will definitely be only one banner.

The excavation here is almost complete. Everyone looked inside Chaohe River. It was pitch dark inside. This should be a house, a side house or something like that. The structure is very complete. The outside has been flooded, and it is blocked by countless mud and rocks around it.

A confined space is formed.

"lamp!"

Lin Fan directly brought a lamp. This kind of portable lamp is made of special glass, which is not harmful to antiques. There is no problem when it is used to directly illuminate ancient papers.

"It's not too high!"
