After some counting, Yang Yi only left the head of a guard machine and an intact cleaning machine in the room, Yang Yi began to study, of course, what Yang Yi cared about the most was the crystal on the head of this machine, as for why the cleaning machine was not working from the space, Yang Yi didn't want to dig into it now.

Yang Yi tapped the head of the machine in his hand with his fingers, making a sound of gold and iron clashing, the material that makes up the body of the machine is an unknown metal, it is an alloy, the hardness is very large, several times harder than ordinary steel, Yang Yi only took a brief look at it and put it down, and then buckled the crystal on the skull with a fairy sword.

This is a red crystal, Yang Yi remembered that the machine of this red crystal was able to emit a red sword, and the sword was very intense, just like a fire attack, at this time, Yang Yi took the crystal in his hand and immediately frowned, because at this time, Yang Yi could no longer feel the slightest energy fluctuation in this crystal.

At this time, the red crystal was really lying in Yang Yi's palm like an ordinary stone, even if he checked it with his divine thoughts, Yang Yi thought that the crystal was broken or the energy was used up, so he immediately took off the crystal on the head of the cleaning machine, but the result was the same.

Some immortal Yang Yi took down all the crystals in the space, but the results were the same, there was not a trace of energy in these crystals, Yang Yi frowned deeply, if one or two crystals were broken, it was still possible, but if they were all broken, it would be impossible.

So Yang Yi guessed that there was no problem with these crystals, the reason why these crystals had no energy was because there was no energy in the first place, and there must be other reasons why they could feel the energy in Atlantis, Yang Yi picked up the head of a machine qì person and carefully observed the structure of the skull with his divine thoughts.

But there is still no gain, although this machine qì human head contains a lot of high-tech, but Yang Yi still did not find the reason for the crystal to become full of energy, and then Yang Yi carefully probed those intact machine qì people with his divine mind and found that the same is the case, the problem does not appear in the bodies of these machine qì people. And the root cause is still in the crystal.

Picking up a crystal, Yang Yi probed into it with his divine thoughts, and after careful observation, Yang Yi found that there was really a lot of information in this crystal, and whether these crystals had energy or not was really related to the internal structure of the crystal. Immediately, Yang Yi seemed to remember something, and quickly came to the study to find some ancient books that Kongkongzi sent that day, and these ancient books recorded some news about Atlantis.

Yang Yi quickly found an ancient book, this ancient book Yang Yi remembered correctly, it should have recorded some information about this crystal. I don't know how long this ancient book is old, the paper is completely yellowed and very fragile, and it needs to be turned carefully, Yang Yi doesn't know where Kongkongzi got this.

On a page, Yang Yi saw information about this crystal, there are some ancient texts that Yang Yi can't understand, and there are also annotations of later generations about these ancient texts, Yang Yi knows that the name of this crystal is called Crystal Crystal, but it is a transliteration, not the meaning of today's Crystal, in the Atlantean language. It means that the Void Crystal is more appropriately called the Dark Void Crystal.

Yang Yi then looked down and knew that the crystal was not an energy crystal in the real sense, and the crystal itself did not contain powerful energy, and the crystal should be an energy extractor and energy converter to be precise.

What is the dark void Yang Yi studied in the Ten Thousand Laws Immortal Sect, the dark void is a vast and boundless void, stored in the gap between the plane and the plane, space and space, and in the dark void space there is a special energy is the dark void energy, which is very similar to the aura. But monks can't use it for cultivation.

Therefore, for the monks, the vast and boundless dark void space is very dangerous, and falling into it is often a situation of death, not to mention whether the dark void space is a storm of dark void energy.

Yang Yi didn't expect Atlantis to find a way to use the dark void energy, and he had already used it. Although the Dark Void Energy is a very low-level energy compared to the Aura and many other high-level energies, the Dark Void Energy is inexhaustible, and it can be said that it is a huge treasure trove of energy, and the Atlanteans have found the key to this treasure trove of energy.

Yang Yi read all the parts of the ancient books related to the crystals and knew a lot of useful information, although Yang Yi learned a lot in the world of the Ten Thousand Laws Immortal Sect. But he was still impressed by the wisdom of the Atlanteans. Although this information is not substantial, it also points out the way to Yang Yi, no longer like a headless fly, it is much easier to return to the house to study the crystal again.

Yang Yi probed his divine thoughts into the crystal, and the internal structure of the crystal was quickly enlarged in Yang Yi's mind, and there was something else in the crystal, Yang Yi found a lot of matrices in the crystal, which were arranged according to certain rules to form one unit after another, and these units were arranged together in an orderly manner to form a new matrix.

After Yang Yi's meticulous exploration, Yang Yi explored all the internal conditions of all the Twin Crystals, and made comparisons to discover the true secret of the Twin Crystals.

The crystal is like the one recorded in the ancient books, not an energy crystal but an energy converter, an energy extractor, after Yang Yi carefully probed each crystal has four large matrices equivalent to the formation, each matrix has a different role, but it is indispensable, the lack of a or damage to a jade crystal can not work normally, these four matrices like the formation are interconnected.

After a long time, Yang Yi figured out the working principle of the Crystal of Grace, Yang Yi activated one of the matrices with his divine thoughts, and the crystal in Yang Yi's hand immediately began to radiate light, full of energy, just like what he saw in Atlantis, this energy is abundant and endless.
