On the side of the Great Dream True Monarch, one finger flicked through the method of the water mirror, and the dream that Ye Zan was in also changed.

In the dream, Ye Zan is fighting with Zheng Tianquan and others, and it is quite difficult to fight with one enemy. He is no longer acting, but he really finds these opponents difficult to deal with, even if he repeats the scene in the barren valley, I am afraid it will be difficult to achieve the same effect.

"Could it be that in the hearts of those people in Tiandao Mountain, these disciples of the Star Sect should have such a strong strength?" Ye Zan felt a little funny. He had actually fought with Zheng Tianquan and others, and the strength of the other party was indeed not weak, but it was obviously strengthened in this dream.

As for Lin Mumu, he was like a puppet at this time, standing next to him and not caring about anything at all. Of course, if Ye Zan hadn't seen through the dream, I was afraid that he would be led to ignore Lin Mumu's performance, and even if he saw it, he would feel normal.

However, at this moment, the dream world suddenly went dark, and the surrounding scenery fell into darkness from far and near. As if the darkness was surrounding Ye Zan, Lin Mumu's figure disappeared into the darkness, and the disciples of the Star Sect who fought with him were also swallowed by the darkness one by one.

Until the end, Ye Zan was also in the dark, as if he had lost his body all of a sudden, and only his spirit floated in the darkness. In all directions, there is nothing, you can't hear or see, you don't feel anything.

"Whew!" Ye Zan blinked his eyes and found himself still lying on the stone bed.

Jumping off the stone bed and coming to the outside of the stone cave, Ye Zan raised his eyes and looked around, especially where Zheng Tianquan and the others appeared in the dream before. But this time, there was nothing there, no Lin Mumu and no Zheng Tianquan, only a few disciples of other sects passed by.

However, Ye Zan did not take it lightly, but gently closed his eyes and once again displayed the artistic conception of the way of insight.

People sometimes have a dream in which they think they are awake, but in fact they are still dreaming.

For example, waking up after a ridiculous dream and getting up to do all kinds of things that need to be done. But when I went out to prepare for school or work, I suddenly found that I had no clothes on, but in fact it was still a dream.

Another example is waking up from a nightmare and lying in bed looking at the ceiling. Suddenly, I found that the ceiling cracked, and the house began to shake like an earthquake, so I jumped out of bed and got under the bed in fright. However, it wasn't until I actually woke up that I realized that it was still a dream I had.

Of course, from a practical scientific point of view, this is not actually a multiple dream. It's just that people have so-called waking dreams, and the brain, for some mechanism, completes the reason for "waking up" and confuses the chronological order.

But it also shows that when dreams are artificially manipulated, multiple dreams can indeed be quite deceptive to people. You think you've woken up, you think you've passed the test, and maybe you'll let your guard down and show your feet. At least, if it were Ye Zan who was the one who manipulated the dream realm, he would definitely use this method.

Therefore, pushing himself and others, Ye Zan did not dare to relax his vigilance.

However, after carefully sensing it, Ye Zan breathed a sigh of relief, and through the artistic conception of the way of insight, everything around him was indeed real at this time.

And on the peak of Tiandao Mountain, Dameng Zhenjun, who broke through the water mirror spell with one finger, was chatting with Chen Daojun when he glanced at the forest trees around him intentionally or unintentionally.

Lin Mumu scratched his head, said with a flattering smile: "Master, you see me here, is it a little disturbing to you?"

"Fuck off!" said Da Meng Zhenjun angrily.

"Hehe, thank you Master, then I'll go first, and the two Daojun will talk slowly. Lin Mumu smiled and saluted Chen and Huang, and then left the peak with a puff of smoke.

"Let the two Taoist friends laugh, this bastard boy has made a rare friend, and he doesn't even want the master. Da Meng Zhenjun shook his head, as if he was quite helpless about Lin Mumu.

"Daoyou is serious, this son has a frank temperament, his heart is like a child, and his achievements in the future are limitless. Chen Daojun said with a light smile.

"Hehe, Daoyou is too famous. Dameng Zhenjun said politely, but he secretly said in his heart: If you know what this kid has done to beg me, I'm afraid you won't say that he is as innocent as a child.

Ye Zan also didn't know that his ability to pass the test of the dream realm was not entirely due to the way of insight. After making sure that he was not in a dream, he returned to his cave, sat down on a stone bench in the outer room, and took out a stone in his hand.

This stone is approximately round and white throughout, like jade. This is actually a spirit stone, but it is a used spirit stone, and the spiritual energy inside is almost exhausted.

The used spirit stone is called the Yuan Stone. Because there is still very little aura in it, the dignitaries in the world like to carve it into jewelry and wear it on their bodies, which is said to have the effect of prolonging life.

However, Ye Zan took out this yuan stone, not to carve ornaments. In the previous battle with Feng Xiandao, Ye Zan used a magic beam cannon, and the energy consumed was spirit stones. The two cannons destroyed Feng Xiandao's two magic weapons, but they also consumed thousands of Ye Zan's lower grade spirit stones.

Therefore, in Ye Zan's Qiankun Ring, there are thousands of such Yuan Stones.

Ye Zan took out this yuan stone, but in fact, he found that the internal structure of the yuan stone was very interesting, like a sponge, which was full of holes that could not be seen by the naked eye.

These hollows are the places where the aura is stored. Moreover, after the void releases the aura, it will also replenish the free aura in the space. It's just that the process of supplementation is extremely slow and almost unnoticed.

After discovering this, Ye Zan couldn't help but have an idea, can we use Yuan Shi to make spirit stones? Just like batteries, after running out of electricity, they can also replenish electricity, can't Yuan Shi replenish spiritual energy?

To others, even if they know this, it is actually meaningless. In this world, the aura has been thinned to a certain extent, in other words, the aura pressure is very low. The release of spiritual energy by spiritual stones can actually be regarded as a process of balancing internal and external spiritual pressure.

After releasing the aura, the spirit stone turned into a yuan stone. The spiritual pressure inside the Yuan Stone is basically balanced with the external spiritual pressure, and naturally there will be no spiritual energy infused into it. It's like two pools with the same water level, digging in the middle, and the water barely flows. Only when the water level of one pool is higher than the other will the water flow towards the lower water level.

For others, if they want to infuse the Yuan Stone with spiritual energy and restore it to a spiritual stone, there is only one way, and that is to infuse their own spiritual energy into it. After all, the aura of a cultivator's dantian, whether it becomes a Dao Jin Lotus or forms a golden pill, the spiritual pressure is far higher than that of the outside world.

However, who would be stupid enough to use the cultivation he had gained through hard cultivation to make a spirit stone? I am afraid that the loss of spiritual energy in this process cannot be compensated for by a single spirit stone.

But Ye Zan is different. He has a method of activating inert aura, which can locally create a high-pressure environment, and can even create a high-pressure device similar to a hyperbaric chamber. Then, it doesn't seem too difficult to place this yuan stone in it, and in an environment of high spiritual pressure, it doesn't seem to be too difficult to convert the yuan stone into a spirit stone.

Of course, after all, it's not like charging a battery, just relying on external spiritual pressure, it can't quickly convert the yuan stone into a spirit stone. Even if there is a high spirit pressure environment, it will take a long time for the Yuan Stone to be converted into a Spirit Stone. For example, those spiritual stone mines have all been naturally conceived after millions of years.

Ye Zan studied this yuan stone at this time, and it was precisely to solve this problem, how to make the yuan stone be infused with aura more quickly.

With a touch of his hand on the Qiankun ring, Ye Zan had another yuan stone in his hand, but the surface of this yuan stone was obviously covered by a layer of spiritual light. This yuan stone is not a real spirit stone, but it has only been placed in a high spirit pressure environment for a period of time.

Don't look at this yuan stone, it looks like a spirit stone in performance, but Ye Zan can see the inside of the yuan stone through the way of insight. If you cut this yuan stone open, you will find that it actually only has the outermost layer to store the aura.

Ye Zan took a closer look and found that it was precisely because of the storage of spiritual energy in this layer on the outside that it blocked the flow of spiritual energy to the deeper inside. For example, in some metals, when the outermost layer is oxidized, it prevents the inside from being oxidized further. Even if the oxide layer is peeled off, a new oxide layer is formed when the underside is oxidized.

Of course, under the action of high spiritual pressure, the aura stored in the outer layer of the Yuan Stone will be pushed and transferred inward. It's just that the speed of this transfer will become slower and slower due to the increase in internal resistance.

According to Ye Zan's calculations, even if it is a low-grade spirit stone, it takes nearly a hundred years for the yuan stone to be placed in a high spirit pressure environment to form. A hundred years of time, compared to the time of natural breeding of the spirit stone mine, is already fast enough to fly. However, for Ye Zan, it was of no use.

Or can the yuan stone be crushed? Ye Zan suddenly thought of the oxidation reaction of metal powder. A piece of iron cannot be ignited directly by fire, but a piece of iron decomposed into iron powder only needs one spark to burn violently.

In fact, the most important and basic material in the formula of rune ink is this yuanshi powder. It is precisely because of the Yuan Stone powder that in the process of drawing the rune, the painter can infuse the aura into the talisman, so that the talisman can have enough aura to exert its effect.

As Ye Zan thought, in the other dimensional space, various robots have started experiments at the same time according to his ideas. The metastone is crushed into nano-scale powder, and then sent into the high-spirit ballast to charge the metastone powder.

Of course, this yuan stone also has a grade, and the difference lies in the amount of spiritual energy that can be accommodated per unit volume. Therefore, in addition to the differences in other materials, the metatolite powder used in different grades of rune ink is also different.

Theoretically speaking, after the top-grade spirit stone consumes the aura, what you get is the top-grade yuan stone, and what you get from the low-grade spirit stone is the low-grade yuan stone. It's just that because the grade of the spirit stone is divided according to the amount of spiritual energy of the spirit stone, the best spirit stone will become a medium-grade and low-grade spirit stone in the process of consumption.

As a result, some of the spirit stones that Ye Zan received from Zhang Qingshan were actually top-grade or medium-grade yuan stones after consuming the spiritual energy, and of course, most of them were low-grade yuan stones. (To be continued.) )
