Energy crystals are undoubtedly an extremely important non-renewable strategic resource for the Gemini civilization.

As an ultra-high-density energy storage medium, its energy density far exceeds that of all known substances, including nuclear fuel.

This cannot be explained by existing physics, so there is also speculation that the energy crystal hides legendary space technology, which is extremely valuable for scientific research.

In addition, its ultra-high instantaneous energy output performance can not only greatly increase the power of weapons, but also play an important role in the miniaturization and enhancement of endurance of weapons.

Its discovery and exploitation, for Gemini, is like the application of fossil fuels on Earth, greatly accelerating the technological development of civilization.

Increasing the power of weapons, increasing the exploration distance of the starfleet, and shortening the voyage time, the energy crystal has an irreplaceable catalytic effect on the interstellar development history of the Gemini civilization!

Because of the important strategic role of energy crystals, ordinary civilizations simply do not trade such important things as trade commodities in large quantities.

Even if the trade commodities this time are based on energy crystals, the two sides only use this as a way to measure value, and it is basically impossible to settle with a large number of energy crystals.

……

"Can you explain what Energy Crystals mean as a 'special commodity'?" Arthas looked at the Black Butler.

"Of course, according to the designated trading rules of our allies, the way in which energy crystals are sold as a special commodity needs to be differentiated separately, and if you want to buy energy crystals, then the only designated exchange goods are ...... 'blank crystals'!"

"Blank Crystal?!" The experts behind Arthas couldn't help but exclaim in unison.

Blank crystal, this is not a rare cosmic mineral, on the contrary, in the Gemini civilization, it is a kind of "waste" that cannot be used.

Because...... It's exactly what remains of the Energy Crystals after they've been depleted!

Ordinary energy crystals are ruby-like red transparent crystals, and when the energy in them is gradually released, its color will gradually fade until it becomes a completely transparent "blank crystal".

What surprised everyone was not that the other party needed this kind of waste in exchange, but that there was some kind of amazing information contained in this condition......

"You ...... Have you mastered the charging technology of the Blank Crystal? One expert couldn't help but exclaim.

Blank Crystals are a waste of the Gemini civilization because the Gemini cannot use them, but the Ante Empire will not be untargeted, and this kind of thing obviously has a certain value to collect.

Combined with the other party's strange move of exchanging energy crystals for blank crystals, the final answer is already on the horizon......

The Blank Crystal Charging Technique, Nie Yun has indeed mastered it!

And this ...... It is also the finale product carefully prepared by Nie Yun for Gemini!

When he had just begun to discover the remnants of energy crystals on the moon, in the face of the huge threat of Gemini, Nie Yun's research on energy crystals mainly focused on how to use this high-density energy in military technology.

In the follow-up research, Yu Lao and others took the research and development path of energy crystal to the field of "art......

Ahem! Of course, it cannot be denied that both sides have made remarkable achievements and have achieved certain scientific research results.

It turns out that the ultra-high instantaneous output ability of the energy crystal is a perfect match for the powerful energy superconducting material such as the mechanical bug, and the terrifying lethality of the Mithril fleet is fully displayed in the Proxima Centauri War!

The research of Yu Lao and others is also gratifying, and it is said that they have developed a fancy "energy crystal bomb" that can inject energy shock waves in a directional and quantitative manner in combination with force field technology......

However, Nie Yun's development and utilization of energy crystals has only been a year, and it is still in the stage of small-scale application, so it was not until the recent start of the war, with the large application and consumption of energy crystals, that Nie Yun had more and more blank crystals on hand, and he turned his attention to this kind of "non-recyclable garbage".

The most valuable use of blank crystals is undoubtedly the repeated charging technology!

If this disposable battery can be turned into a rechargeable battery, then the energy crystal can be used as an inexhaustible source of conventional energy, and the strategic value will immediately increase countless times!

However, judging from the information obtained by the Gemini, they have made little progress in the development of this technology.

Throughout the interior of the Gemini, the Blank Crystals have not yet found any effective use, and some Gemini builders have even treated them as rare building materials.

Therefore, at the beginning, Nie Yun basically did not have much hope for research in this field.

After all, with the Gemini Star exceeding his own scientific and technological conditions, and researching energy crystals for so many years without progress, Nie Yun didn't feel that with his current scientific research strength, he could catch up with the other party in a short period of time.

However, he had no intention of inserting willows into the shade, and Yu Lao almost habitually said, "Do you want to try the Mithril material?" Nie Yun was directly reminded.

In their own forces, if there is anything that can have a direct impact on the strange things of the universe, it seems that the only one is the mechanical worm that is suspected to be a strange thing in the universe.

Whether it's the combination of tiny slag particles into complete energy crystal blocks, or the "vampire serum" obtained by mixing it with eaux-de-vie, it undoubtedly illustrates the unique ability of the robot to transform both items.

Then Nie Yun used a mechanical worm to experiment with the blank crystal......

The final result of the experiment was undoubtedly a pleasant surprise!

The mechanical insect is actually able to use its own internal energy to charge the blank crystal!

Although the energy reserve capacity of the mechanical insect is far less than that of the energy crystal, even if it is poured out, it can only make a small piece of blank crystal appear a faint red trace, but the energy does enter the blank crystal......

This means that as long as it provides a constant supply of energy for the Robot, it can act as a special "transformer" to charge the Energy Crystal!

This discovery made Nie Yun ecstatic.

But...... The time of happiness is short-lived, just when Nie Yun thought that he was about to become rich overnight and had an endless energy crystal, the follow-up experiment poured a basin of cold water on Nie Yun.

Because after 3 repeated charges, this blank crystal actually shattered directly into a pile of white powder, and even mechanical insects couldn't put it back together.

Serendipitous phenomenon?

Maybe the mechanical bug's movements are too rough?

Well! Definitely!

Robotic Bug: "......" (‵o′) convex

The undying Nie Yun did several experiments again, but to his disappointment, no matter how gentle the charging process was, the result was still the same every time.

An energy crystal can only be recharged three times at most before it can be reused completely.

Obviously, although this charging test can charge the blank crystal, every repeated flushing of energy will cause certain damage to the energy storage structure of the energy crystal itself.

After a maximum of three times, the energy crystal, whose internal structure has been completely destroyed, will disintegrate on its own.

Nie Yun finally had to accept the cruel reality depressedly.

He felt as if he had won the "One More Bottle" three times in a row, and just when he thought that he had received the "Blessing of God" of the Infinite Chain's "One More Bottle", the next bottle appeared with a "Thank you for your patronage!" ”……

The ups and downs of life are so exciting......
