A treasure-appraisal maniac

Maps drawn by Naimazhen were very common in ancient times.

It is clear what shape represents what meaning.

This kind of map was widely circulated, and this version was still used in the world until the late Republic of China.

Therefore, when Lu Fei looked at this map, it could be said that it was clear at a glance.

But what puzzles Lu Fei is, why draw water vapor when it is clearly marked with water bubbles?

Isn’t this unnecessary taking off your pants and farting?

Lu Fei scratched his head in confusion and accidentally glanced at the steaming tea cup next to him, and his eyes suddenly lit up.

"yes!"

"This water vapor also has a broad meaning. It can represent water mist or water vapor!"

"If it's water vapor, then these bubbles are probably hot springs!"

Lu Fei murmured, his heart suddenly enlightened.

However, this is just Lu Fei's speculation, and there is no evidence to confirm it.

Putting down the water vapor for now, Lu Fei continued to study the valley.

Continuing to extend all the way up, the terrain becomes wider and wider.

However, the valley is not too deep, only about three kilometers in length.

There were eleven large and small blisters along the way, which were truly bizarre.

Once inside, the terrain suddenly opens up and is more than three times as wide as the middle.

From the map, the innermost terrain is a relatively regular square.

Other than that, there's nothing special about it.

However, Lu Fei turned his attention to the entire valley and immediately made another discovery.

The entire valley all the way to the innermost trend forms an "A" shape?

Hiss——

Does this have any special significance?

Many ancient tombs of ancient princes and generals have A-shaped tomb passages.

Seeing this kind of tomb passage, you can immediately distinguish the ancient

Tomb specifications.

But what does this shape mean when used in a valley?

Could it be that this valley was also created by man?

Looking at this strange shape, Lu Fei fell into deep thought again.

The A-shaped valley is a bubble with water vapor.

"Huh??"

Suddenly, a bold idea burst into Lu Fei's heart.

Could it be that the hiding place of the ultimate treasure is in the mountains next to the valley?

Lu Fei's idea was not groundless, but had his own basis.

If you assume that the water bubbles in the valley are eleven small hot springs, it would be a bit interesting.

The formation of hot springs has its particularities and can generally be divided into two types.

One is formed by magmatism within the earth's crust, or is accompanied by volcanic eruptions.

Extinct volcanic terrain areas that have experienced volcanic activity, the surface has been raised due to the movement of crustal plates, and there is still uncooled magma underground, which will continuously release a large amount of heat energy due to the concentration of heat from such heat sources.

Therefore, as long as there are water-bearing rock formations with pores nearby, they will not only be heated into high-temperature hot water, but most of them will boil into steam, mostly sulfate springs.

The second is formed by the infiltration and circulation of surface water.

That is to say, when rainwater falls on the surface and penetrates downward, it penetrates deep into the aquifers deep in the earth's crust to form groundwater, such as sandstone, conglomerate, and volcanic rocks, which are good aquifers.

Groundwater is heated by the geothermal energy below to become hot water. Most of the deep hot water contains gases. These gases are mainly carbon dioxide. When the temperature of the hot water rises, if there are dense and impermeable rock layers blocking its way, the pressure will become higher and higher. , so that hot water and steam are at high

In a state of pressure, if there is a crack, it will surge up.

After the hot water rises, the pressure gradually decreases as it gets closer to the surface. As the pressure gradually decreases, the gas contained in it gradually expands, reducing the density of the hot water. These expanded vapors are more conducive to the rise of the hot water.

The rising hot water then repeatedly circulates with the sinking cold water that is heated later due to the pressure generated by the different densities to produce convection. When the resistance of the open fissure is small, it rises along the fissure and gushes out of the surface, and the hot water is endless. It rises and eventually flows out of the ground, forming a hot spring.

In combination with the terrain of high mountains and deep valleys, the ground water at the valley bottom may be higher in the mountains and the groundwater level in the middle is lower. Therefore, the bottom of the deep valley may be the place where the hydrostatic pressure difference is the largest, and the upwelling of hot water should also be the most likely to gush out from the valley bottom. Most hot springs Occurs on a river bed in a valley.

However, no matter which one it is, it is inseparable from one mineral, that is "sulfur".

Looking at the forest and the not-so-high mountains on the map, it is certain that there are no volcanic mountains here, and naturally there should be no hot springs.

But if there is another hypothesis, that is a different matter.

In ancient times, special protection measures were required whether it was a top-level ancient tomb or a high-end treasure hiding place.

Some are for anti-theft, some are for waterproofing, some are for anti-corrosion and so on.

Of these safety measures, sulfur is the most essential.

The sulfur combines with the triple soil, and after seeping into the rainwater, a chemical reaction occurs, making it indestructible.

The minerals contained in sulfur are not only sterilizing, but are also severely corrosive to human internal organs and skin.

It plays a particularly important role in preventing theft.

Most of the ancient tombs that Lu Fei had excavated before had a protective layer of sulfur, but they were not very deep.

In addition to the age, it will not cause much harm to experienced people.

Why Sulfur Protects

The layer is not deep, firstly because this mineral was hard-won in ancient times.

The second reason is personal financial issues.

If you don’t have money and can’t afford too much sulfur, you can only do what you can.

But Yuanmeng's treasure is different.

This is a treasure hidden by a dynasty, and it is a treasure hidden by the most courageous Yuanmeng cavalry in ancient times.

At that time, the Mongolian cavalry conquered most of the Eurasian continent, obtained countless treasures, and their financial resources were astounding.

It can be said that you can have as much mineral as sulfur.

The treasures they hide must have the highest level of protection.

It is not a problem to use several meters or even dozens of meters of sulfur minerals for protection.

Not to mention tens of meters, even a few meters of sulfur protective layer is a considerable number.

It is not surprising that there are so many sulfur minerals that react chemically with the surface and underground water to form hot springs.

If that were the case, it would make sense for so many hot springs to be located in the valley.

hey-hey!

The conditioning became clearer and clearer, and Lu Fei became more and more convinced of his judgment.

At first, Lu Fei judged that the treasure was hidden under the steamed bun-shaped mountain bag.

Later, Lu Fei discovered that it was just a cover-up.

In fact, the real treasures are hidden underground on both sides of the valley. Otherwise, there would not be so many hot springs on the surface.

Basically confirming his idea, Lu Fei sincerely admired the wisdom of the ancients in his heart.

That steamed bun-shaped mountain must have been man-made.

With such a huge project and such a weird shape, no matter who sees it, they will firmly believe that the treasure is hidden there.

Because no one will spend huge manpower, material and financial resources to build this useless mountain bag.
