For the earth, that hole was just a puny pit on an extremely thin layer of skin.

This layer of skin is the earth's crust. The average land thickness is 33 kilometers, the thickness of the mantle is about 2,865 kilometers, and the crust is less than a fraction of the mantle. So how can humans even penetrate this layer of skin?

Bai Ge knew that there were a large amount of minerals hidden in this thousands of kilometers scale that humans could not explore.

There is a diamond layer at a depth of 600 to 1,000 kilometers.

The high-pressure and high-temperature environment allows atoms to be rearranged and form a large number of diamonds. These diamonds are often extremely huge, and perhaps a diamond occupies a larger area than Los Angeles.

Such a diamond layer is everywhere in the lower mantle.

In addition to diamonds, there are more ‘gems’ in the mantle, and countless peridots and spinels are numerous, and more than 50% of the mantle are all these things.

Although it can only occupy a small proportion of gem-level, this proportion is quite large under the huge number of numbers.

If the deep sea is a treasure land, the deep mantle itself is a huge treasure, and 90% of the resources on the surface come from the underground.

If you have to find a shipwreck at the bottom of the sea, and if you have to dig an ancient tomb in the deep mountains... If you have to take a "stone" deep in the mantle, it's enough to get a "stone".

Unfortunately, the existing conditions of human beings are completely unable to reach the mantle, where there are high temperatures of 4,000 to 6,000 degrees Celsius, not to mention the pressure.

Various extreme environments make it a real hell, with high temperatures dissolved mantle matter and liquid lava ravaging the underground.

If humans want to go to such a place, it will take a long time to develop.

However, Bai Ge can solve this problem by using a containment now.

A black bow tie can make him not afraid of the extreme environment of the mantle, and high temperatures and high pressures are no problem.

"Unfortunately, the characteristics of absorbing and storing heat energy are much more difficult than safe power storage!"

If Bai Ge can absorb heat energy deep in the mantle, then he can walk a thousand kilometers underground, not only can he obtain many gems, but he can also obtain a continuous stream of heat energy!

But in fact, this is difficult to achieve and there are too many places involved.

He had to make himself not afraid of the high temperature of 6,000 degrees Celsius, the high pressure of a million times the surface, and ignore the lack of oxygen and various chemical reactions.

"Even if all of these are achieved, I can't use myself to absorb heat, because with my weight of less than fifty kilograms, I can only get about three hundred degrees of electricity in an environment of 5,000 degrees Celsius."

"Heat is heat, and heat energy is heat energy."

"The heat energy I can absorb is proportional to my mass. If I want to change this, it violates the laws of thermodynamics. I might have to pay tens of thousands of times more energy than the 'safe power storage characteristic' to realize..."

"No, I just need to add a 'heat energy instantly converted into electricity' characteristic, which seems to solve this problem with the power storage characteristics I already have."

"And, you don't need your body to absorb heat, and you can directly enter the high-temperature substances into your mind and then convert them..."
