Otherwise, judging from the data that the construction of any dragon city consumes tens of millions of tons and hundreds of millions of tons of high-quality metal, even if there are hidden forces secretly covering up, it is impossible for humans in modern society not to detect the traces left here.

A more reasonable inference is that the dragon civilization separated a large amount of these metals from the magma through some unknown advanced alchemical process - most of the "mantle drilling" technology mentioned in the previous Nibelung bottom dream

That's the point.

Since the dragon civilization has verified the feasibility of the technology in advance and proved that this method has certain advantages over traditional mining techniques, and from the perspective of the compatibility of alchemy with its own understanding of spiritual practice, it can undoubtedly be used as a future technological development

direction.

After a period of derivation, although Zhao Qing has not restored the true appearance of this technology, based on her insights into relevant scientific theories and the use of Qi, it seems that she has initially developed another rather ingenious method of magma mining.

Technology, in theory, has extremely broad prospects.

That is to follow the principles of natural changes, simulate various processes of magma mineralization, and accelerate them to generate high-grade mineral deposits at designated locations, so that they can be mined and smelted directly. The key to this series of technologies is actually to see

Like insignificant bubbles.

It is based on a profound understanding of the complex physical and chemical processes in mantle magma and is called "Mantle Magma Micro-Nano Bubble Mineral Extraction Technology (MMMBMET)".

"The core of this technology is to use true gas to control and simulate the formation and movement of bubbles in magma. Through ultra-long and high-strength pipes that penetrate into the mantle's asthenosphere, true gas with special properties is input into it, making it a carrier, rich and

A natural carrier of various minerals.”

"Under natural conditions, low-level Qi will not dissolve after being injected into water, but will form countless small bubbles ranging from tens of nanometers to hundreds of microns. Due to their extremely small size and extremely high specific surface area, they can extremely

The earth increases its contact area with the minerals in the magma."

"In the process of rising, the small bubbles of true gas continue to merge to form larger bubbles through the principle of minimizing surface tension. At the same time, they adsorb the surrounding high-density sulfide melt droplets, and use the buoyancy of the bubbles to float up to accelerate the sulfide minerals in the magma.

The process of being brought to the surface.”

"The dissipated cold air has the effect of spontaneously forming an air field, and will actively swim to hot areas that they have not passed through. In the complex and changeable turbulent convection environment near the mantle hot spots, through relevant calculations and optimized paths, a small number of bubbles will

A volume that can cover a large area of ​​magma.”

"The phenomenon of liquid phase immiscibility during the evolution of magma causes the gas phase components rich in ore-forming metal elements to separate from the melt phase and be captured by the true gas vesicles. The stability of the true gas itself at high temperatures and high pressures

, played an irreplaceable and huge role during this period."

"At the same time, complex water-rock reactions will also occur between the water in the magma and the sulfide droplets, leading to the activation and extraction of minerals."

"Especially in areas with dynamic changes in the stress field, such as at the intersection of fractures and fissures, the intense boiling and brecciation process of magma accelerates the dissolution and reprecipitation of minerals, further enriching the mineral particles carried by the bubbles, forming easily extracted

Mineral clumps.”

She thought secretly in her heart: "Just add some alchemical matrices to control the aura. In theory, the mineral deposits that originally took millions of years or even longer to form can be formed in just a few months or even weeks."

It has achieved results, and the grade of the ore can reach an extremely high level.”

Perhaps, the cost of its initial construction is high, but later on, it will become as convenient as a water plant. As long as bubbles are continuously injected, various designated minerals related to the type of true energy can be obtained at the exit.

There are almost no unnecessary movements.

Overall, it seems that all aspects of "earth, fire, wind, and water" are involved. If the dragon civilization's magma mining technology is similar to it, it can be regarded as a peak alchemy work that integrates the four elements!
