Although Li Qingyu recognized that the object on the picture was a first-class Lingjing, he didn't say it. He just listened to Zhou Xianguang's introduction: "it's called Lingjing. It's very expensive. At least we haven't found it naturally in our space. This thing not only contains its own spiritual power, but also after the spiritual power contained in it is exhausted by the monk, as long as it depicts the absorption array, he can absorb the aura of heaven and earth, and restore to the spiritual crystal containing spiritual power! "

Li Qingyu's eyes lit up and asked, "commander Zhou means that a piece of crystal can be recycled like a battery charging and discharging?"

"Rechargeable batteries? Hehe, your metaphor is appropriate. However, in order to reuse Lingjing, we must first depict the absorption matrix. Otherwise, after the release of the spirit power in the Spirit Crystal, it will just go into the garbage heap! " Zhou Xianguang said with a smile.

Li Qingyu couldn't help but feel ecstatic!

When Niu Dahuang gave him 53 pieces of Lingjing, he just told him to hold Lingjing in his hand, and then he could absorb the spiritual power of Lingjing for his own use, and speed up his cultivation. If the spirit power contained in the spirit crystal is exhausted, the Spirit Crystal will become a hard stone and lose its function.

Now Zhou Xianguang says that Lingjing can be recycled! That's great!

Although the whole aura on the earth is exhausted, there are still auras in some places, such as Dongshan in dashangou village, Li Qingyu's hometown, and Jinli Lake in Jinjiao University!

In the future, Li Qingyu will put the exhausted Lingjing in these places, and then he can absorb the aura of heaven and earth again. In this way, Li Qingyu will recycle these Lingjing, and then he can use them to cultivate quickly everywhere!

However, Li Qingyu didn't know how to portray the absorption array, so he asked, "commander Zhou, do you know how to portray the array on Lingjing?"

Because Lingjing is so precious, Zhou Xianguang didn't expect Li Qingyu to have it. He thought Li Qingyu just asked casually, so he said casually: "I don't understand. At present, only the master of array in lingxu world knows this. But we also have a special array research center, where the professors are overcoming this difficulty. Maybe one day, we will be able to portray and absorb the array. "

"What kind of warrior are these old professors?" Li Qingyu asked subconsciously.

"Ha ha, you are wrong this time. They are not warriors at all, they are pure researchers! But they are all learned academicians of the state Zhou Xianguang said.

"Ah? How is that possible? " Li Qingyu stares big eyes, inconceivable says. In his impression, Xiuzhen and science are mutually exclusive. How can those scientists know how to describe the Dharma array?

Zhou Xianguang seemed to have guessed Li Qingyu's idea and said with a smile: "the Dharma array is composed of two parts: the array base and the spiritual power. The description of the array base is to rearrange and combine the molecules of matter according to the mathematical model, so that they can contain the spiritual power. There is no need for the warrior to participate in this process. For example, the design of the normal array and the array base on the special bullet head of the star river fleet soldiers is completed by the scientists of the research center, while the depiction is completed by the high-precision lathe. Finally, it's up to the warrior to inject spiritual power into the array base and let the array base start. At least the martial arts of Xiaocheng in xuanjing are competent! "

Li Qingyu can't help but have a fresh look. It's the first time that he heard that Fazhen can play like this!

It seems that the sky demon star, which has developed the cultivation civilization, is not as good as the earth! At least they don't know how to carve the magic array on Lingjing and let Lingjing reuse it!

Of course, it is also possible that there is no lack of Spirit Crystal in the demon star, so no one studies the reuse of waste Spirit Crystal, right?

"No, I have to visit the old scholars in the array research center when I have time! Learn how to describe the array! Then we will see if the sophisticated instruments are for sale. If they are for sale, we must buy one! " Li Qingyu has a secret way in his heart.

Zhou Xianguang didn't know what the hell Li Qingyu was up to. He just manipulated the scroll screen on the wall and continued to play the animation.

There are thirteen spirit crystals on the scroll screen. They are arranged according to a certain rule and fall into a green space. Then there is a gas like water vapor, which quickly gathers to the thirteen spirit crystals from afar, and then all the water vapor goes into the spirit crystals!

Some of the animals around Lingjing began to flee, some died gradually, and the green trees and grasslands began to wither and wither rapidly, and then disappeared in the wind and rain. Even the living materials in the soil also died quickly, and the soil quickly became a desert!

"This is the simulation animation that the hermit family uses the Spirit Crystal to plunder the aura of the first world, and then makes the soil Sandy. Of course, this is just a simulation animation after all. In reality, Reiki is not as visible as water vapor shown in animation. They can't be seen or touched, and even ordinary people can't feel them. Moreover, the Reiki absorption speed of Reiki crystal is not as fast as that of simulation. Therefore, the Reiki plunder of our space by the hermit family is a hidden process, and the formation of desert is also a gradual process. "

As Zhou Xianguang was saying this, he suddenly thought of something and asked, "by the way, we have been talking about aura for a long time. I think you should know what aura is?"

"I know." Li Qingyu told the truth, Niu Dahuang gave him a detailed explanation.

"What do you know about Reiki?" Zhou Xianguang asked again.

"It can help the monks to practice. It is because the aura of the earth is weak, and the friars have no aura to absorb and use, that they will enter the end of the Dharma era. As a result, there are only martial arts on the earth, but few real friars! " Li Qingyu repeated what Niu Dahuang had told him.

Zhou Xianguang's eyes suddenly brightened and said with a smile: "ha ha, Mr. Li has had an adventure! But Mr. Li only knows one thing, not the other. Aura can not only assist monks to practice, but also is the source of life! It is because of aura that life is born on earth! And aura also has a strong purification effect on the environment. Now the earth's environment is getting worse and worse, not only because of industrial pollution, but also because of the depletion of aura, which makes the earth lose its self purification ability! "

"The hermit family is really vicious! Dout, damn it Li Qingyu could not help but make complaints about it.

"These are not the only evils of the hermit family. They even went to the first world to find children with cultivation qualifications, and then forced them to be disciples in the lingxu world! In short, they steal children! According to our incomplete statistics, from 1956 to today - January 20, 2015, they stole a total of 23631 children from our space! This is still incomplete statistics! " Zhou Xianguang said with a heavy tone.

Li Qingyu's cheeks trembled!

23631 children! There may be more than 50000 families involved! The hermit family can do everything for their own interests!
