For the surprise of the three elders, Lin Jingyu seemed to have expected it.

Regarding the source of the astigmatism stone, Lin Jingyu does not intend to hide it, and it is not a secret matter, presumably every disciple of the Huashan faction has some astigmatism stones in private, so the Huashan faction should be acquiesced to this, and will not say anything.

So he told the situation, this astigmatism stone was given by Hua Fenglin, and it was given to Ouyang Yueyue.

Next is the main topic, that is, what the three elders want to ask, why did Lin Jingyu bring so many astigmatism stones with him, according to the meaning of the three elders, Lin Jingyu must have his own reasons.

"Third Elder, for these astigmatism stones, have you ever tried to extract the energy inside and use them for your own use?"

"It's true, I've tried this, but it didn't work, and I haven't tried it since, after all, no matter how much I try, it's futile, although the energy can be extracted, but no matter what, it just can't be used for my own use."

The three elders stated the crux of the matter.

Lin Jingyu was able to ask like this, which proved that he understood some of the things in this, so the third elder said it directly.

As for why Lin Jingyu knew this, the third elder didn't plan to ask too much, after all, it was not a secret.

"Third Elder, this problem you have encountered, the disciple has also encountered." Lin Jingyu said.

"Oh? Have you tried to use the energy in it for your own use? The Third Elder didn't ask again.

"Yes." Lin Jingyu nodded.

A trace of excitement flashed in the eyes of the third elder, but it quickly turned into disappointment, or saw through something, and then said: "Xiao Yu, since you have also encountered such a problem, I believe you have also seen clearly, the energy in the astigmatism stone cannot be used by us at all, even if the energy is more and purer, it is useless, these astigmatism stones, its effect only seems to be like its name, glowing." ”

Lin Jingyu saw that the three elders were helpless on their faces, thirsting for the energy contained in the astigmatism stone, but they couldn't do anything, in other words, they couldn't stop.

However, before Lin Jingyu could speak, the eyes of the three elders flashed with excitement, and their eyes fixed on Lin Jingyu's face and asked, "Xiaoyu, are you ...... Is there anything new to discover? ”

Originally, he wanted to ask if you had made any breakthroughs, but that seemed too direct, and in the end it was replaced by something new, which was more appropriate.

Lin Jingyu smiled with a hint of admiration on his face.

"The third elder is really powerful, but the disciple has not made any new discoveries, but has gained some experience from it, and has made a little progress in this regard." Lin Jingyu said.

"Small progress? What is the progress, tell me about it? The Third Elder suddenly became a little nervous.

"Third Elder, the previous disciple studied the astigmatism stone for a long time, and finally found that the energy in it is not unusable, on the contrary, as long as it is used by some means, those energies can still be used by people."

While speaking, Lin Jingyu looked serious, without a trace of jokes.

"Be specific." The three elders couldn't wait.

"Well, that's ...... exactly."

……

In the next few minutes, Lin Jingyu told the three elders how to obtain the energy contained in the astigmatism stone and how to use it for his own use, without missing a single thing, and the three elders nodded from time to time to express understanding.

"Just like that, the energy was transformed by you?"

The three elders couldn't believe it, and what Lin Jingyu said seemed to be too simple.

"That's true, the disciple uses this method to obtain, if the three elders don't believe it, the disciple can demonstrate it on the spot, and it can be completed quickly, in a few minutes." Lin Jingyu said.

The three elders were skeptical, and were silent for a few seconds, and then said, "Well, then you try." ”

Lin Jingyu nodded, then turned to the box in front of him, and looked at the white astigmatism stone in the box, and the faint white light emitted out, which looked very wonderful.

With a wave of his hand, a scattering stone flew out of the box, not fast, and appeared to be steady.

Then the astigmatism stone hovered in front of Lin Jingyu and the three elders, motionless in mid-air, Lin Jingyu released his true qi and wrapped the astigmatism stone......

So, under the gaze of the three elders, the astigmatism stone changed, and the bright light that it originally emitted appeared abundant, and as time went by, the light became weaker and weaker, and these changes could be distinguished by the naked eye.

The original curious gaze of the three elders gradually turned into surprise, and the light emitted by the astigmatism stone weakened, which meant that the energy inside gradually decreased, and the energy inside decreased, which meant that it was withdrawn by Lin Jingyu.

And it seems that Lin Jingyu seems to be absorbing something.

In less than five minutes, the astigmatism stone hovering in mid-air had become dull, until finally the light completely faded and turned into an ordinary stone, just a little more beautiful than ordinary stones.

Without the light, Lin Jingyu had nothing to continue to absorb, and with a wave of his hand, he put the astigmatism stone that had lost energy back into the box and recycled it, but it couldn't be thrown away.

"Xiao Yu, have you exhausted the energy in it?"

At this moment, the three elders were already full of surprise, incredible, and unbelievable.

"Exactly, the energy of that astigmatism stone has been drained by me, and it has been turned into my own use." Lin Jingyu nodded.

"How could it be ......"

The three elders subconsciously said these words, which were enough to express the shock in his heart.

There was a reason why Lin Jingyu's approach caused the three elders to react so strongly.

Just imagine, if according to Lin Jingyu's method, the energy contained in the astigmatism stone can be extracted by people and can be turned into their own use, what kind of impact will it bring.

If every disciple of the Huashan Sect was allowed to use this method to cultivate, it would be a matter of twice the result with half the effort.

For the astigmatism stone mine in the territory of the Huashan faction, the reserves of astigmatism contained in it are claimed to be not much, but the three elders who are insiders know that the astigmatism stone of the Huashan faction is a huge amount, at least in a hundred years, according to the current mining rate, it will not be exhausted!

With so many astigmatism stones, if you use them to assist in cultivation, it will be something to be excited about.

However, with so many astigmatism stones, they are mined and sold every year, but they only serve one purpose, and that is - lighting.

Ever since he knew that the astigmatism stone contained a lot of energy in it, the three elders had always felt that it was a waste to use the astigmatism stone for lighting, but even if he felt that it was a waste, after many attempts, he had to give up, and those energies really couldn't be used by people.

It's like, there is a fragrant piece of braised pork in front of you, but you can only look at it, what kind of depression is this.

Now, Lin Jingyu has broken this 'theorem', and what everyone thinks cannot be changed has taken a turn for the better here in Lin Jingyu, can you be excited?

"Xiaoyu, according to what you say, I also think it makes sense." The Third Elder said.

"Then the three elders give it a try?" Lin Jingyu said.

"Okay, give it a try."

The three elders had a feeling of eagerness to try.
