When Wen Ming stepped into the stone house with a few companions, he could feel the undisguised gaze of the green elder behind him, but fortunately, until he walked into the stone house, the other party didn't say anything and would make any moves.

He was really afraid that the other party would open his mouth and let him stay, and he was too uncomfortable in his heart to face him, even if the other party was like the predecessor in the legend and wanted to give him any benefits, he felt that he would rather not, thinking of facing him alone outside, or even calling him to the stone house on the right, his heart trembled.

In addition, he was also distracted by the fact that this Green Elder must be the owner of the power of Taiyin, but he didn't know what level of power it could affect the entire forest, and at the same time, it could give them great fear without any momentum, and even the Green Immortal Warriors like Mentor Lin were afraid of him.

A desire rose in his heart, he also wanted to have this kind of power, he didn't need to do anything, he didn't need any pomp, he could make people feel great power, the so-called low-key pretending, that's probably it, hehe!

At the same time, he is also looking forward to the day when the attributes of the stars will change qualitatively, otherwise his current star battle qi is really nothing to look at, and he can still occupy the high quality of battle qi when fighting with people before, and has the power of not losing or even stronger than others.

But when he arrives in World City and Purple Cloud Academy, the quality of the people he will come into contact with in the future will only be higher than the other, and his advantage will become a disadvantage, and if he wants not to fall behind, he has to improve faster than others!

......

"Wow!" Miraculously, as soon as you step into the stone house in the middle, your eyes are no longer dark, but full of magnificent and bright colorful colors, obviously without the slightest barrier, this color is imprisoned in the stone house like a real thing, and it can't be transmitted to the outside, including sound.

The light source was a few crystals placed around a stone house of about two or three hundred square meters.

Because of the large number of students, the stone house is a little crowded, even though it is large. Wen Ming could only see one crystal, and he was stunned when he saw that crystal, because it was a crystal that was very similar to his Star Yuan Saint Crystal.

The same icosahedron, the same interior has nebulae.

The difference is that this crystal turned out to be a pure icosahedron, and it was much larger than Wen Ming's Xingyuan Saint Crystal.

With his current eyesight, the lens can be distinguished even if it is a little less "positive", or in other words, in his opinion, even if there is an extremely small and inadequate standard of crystal structure, it is already negligible in theory and practice.

In addition, the distance between the two relative apex of this crystal has reached about 8 centimeters. It's a lot bigger than his 5 centimeters.

"This should be the Xingyuan Saint Crystal!" Gu Qiyao said, looking at the inscription before adding, "It's the real genuine Xingyuan Saint Crystal." ”

Several people had never seen Wen Ming's inferior Xingyuan Saint Crystal, but they all knew the existence of the inferior Xingyuan Saint Crystal, and they originally wanted to see it when they received the reward, but when they heard Liu Hong say it solemnly, they were embarrassed to open their eyes.

However, Gu Qiyao's family is a defective Saint Crystal with other attributes, and he has also heard of the real genuine Saint Crystal, so it is natural to be able to surmise that this crystal is a genuine Xingyuan Saint Crystal.

At this moment, Mentor Lin's voice rang out:

"Individual students have probably guessed what these crystals are. But most people probably don't know about it.

These crystals are the legendary holy crystals! they are the energy crystal nuclei of the holy beasts, if you hadn't come to the Purple Cloud Academy, most of you would probably never have the chance to see any of the holy crystals in your lifetime. ”

In an instant, the eyes of almost all the students lit up, giving people the illusion that the stone house was a little brighter.

It's not that the students don't know it. On the contrary, the part with the brightest eyes were all students who had heard of the Holy Crystals and knew their functions, and the other part didn't know what the Holy Crystals were, just because they heard Master Lin say that they were the energy crystal nuclei of the Holy Beast. Naturally, they knew that these crystals were rare things, and they were curious and eager for the Holy Crystal, but in fact, they didn't know what use the Holy Crystal was for the warriors.

Tutor Lin looked at the students' eager eyes very happily. As if he could get some happiness out of it, he waited for a while to see that no one was dizzy and did anything inappropriate, and then he sighed a little disappointed, and continued:

"Isn't there anyone moving, no one acting? ”

Mentor Lin immediately gained hundreds of white eyes, who would not be impressed, but who would be stupid enough to dare to turn their hearts into action?

"It's a pity, why haven't you met a fool for decades. Tutor Lin's face was full of regret, and then he said with a slight straight face:

"They are Saint Crystals, and they are also part of the Battle Atmosphere Quality Measurement Device, and the reason why the precious Saint Crystals are loaded on the Battle Atmosphere Quality Measurement Device is to be able to measure the Battle Atmosphere Quality more accurately.

If you want to measure the quality of war qi, it is natural to inject war qi into the measuring device, then the measuring device will more or less leave traces of war qi, which will make the final measurement result have an error, and the more times the measuring device is used, the greater the error.

If the measuring device is a bargain and a mass-produced item, then it is a big deal for everyone to test it with a new device, but in fact, the measuring device is not only a scarcity of materials, but also extremely difficult to produce and accurately debug in the early stage, even with the wealth of the school palace, it is impossible to consume.

Therefore, our measuring device is equipped with Saint Crystal, the battle qi will pass through the Saint Crystal first, and the Saint Crystal will filter out all the personal breath, and then after the measurement, it will absorb all the battle qi in the measuring device, so that when the next surveyor is measuring, the measuring device will not have traces of the battle qi of the predecessors.

Some people may think that it is okay to use defective Saint Crystals, why use genuine Saint Crystals that are many times more precious than defective Saint Crystals.

Then I tell you, it's a no-no!

Because there are too many people and the breath is mixed, you probably no one notices that there is actually no attribute energy in it. ”

Hearing this, most of the students took up the exercises, and felt it carefully, sure enough, there was no attribute energy in the air, and the reason why no one found it was because as Master Lin said, the breath was too mixed, and there was energy circulation in everyone's body, and a person's energy fluctuation was very slight, and there were many people, and in such a relatively sealed stone house, it felt like a chaos.

Mentor Lin continued:

"The reason why there is no attribute energy is to keep the holy crystal in an empty energy state, of course, this refers to the free energy, and the energy that has been crystallized does not count. ”

The essence crystal on the outer layer of the holy crystal is the crystallization of energy with the original Yuandan substance as the crystal nucleus, and the brilliance in the stone house is not the light of energy, but the radioactive brilliance of the crystallization energy of the crystal.
