Of course, this kind of rune is likely to be a key way to use and manipulate power in a unique cultivation system.

So being able to possess such a special ability is not too surprising for Li Yue.

Moreover, it also gave Li Yue some understanding of the truly important role of these runes.

As a result, in the process of engraving this barrier, the rune that seemed to be the easiest to engrave was put at the end.

At the moment when he began to reproduce the three-dimensional image in his mind according to the shape of the rune on the barrier, Li Yue felt that his guess was not wrong.

Because, at the beginning, he used his mental power to re-engrave the first rune.

Li Yue felt a very special feeling.

According to normal circumstances, Li Yuelian's relatively subtle lines on the barrier can be redrawn in his mind without any problem.

This is enough to show that at this time Li Yue's control of mental power has reached an incredible level.

It should be easier and easier to draw this kind of strange rune, which is huge and easy to figure, to be more normal than before.

However, at the moment when it was re-enacted in my mind according to the rune above the barrier.

Li Yue felt that this was not at the same level as the difficulty of re-engraving the subtle lines just now.

A more vivid metaphor is like Li Yue’s original place on the earth. After the technology has developed to a certain extent, there is a huge difficulty gap between manufacturing a 14-nanometer lithography machine and a 7-nanometer lithography machine.

At this moment, different from before, when Li Yue reproduced various details, it was only a test of Li Yue's proficiency in spiritual control.

At this moment, Li Yue suddenly felt an inexplicable pressure.

And this kind of inexplicable pressure is no stranger to Li Yue.

Because he once felt oppressive forces like this.

And this kind of power is the special power that is repelled by the will of the whole world and wants to drive you out of this world!

It's as if the sky and the earth have become a big mountain, suddenly oppressing your entire body.

Of course, this oppressive force does not actually act on the body, but on your spirit!

And Li Yue just started to reproduce the first pen, so this oppressive force is not very strong.

But if a person is not prepared, it is easy to be caught off guard by this sudden pressure.

Fortunately, Li Yue felt the extraordinary of this kind of rune before, so the process of re-engraving this kind of rune was completed at the end.

Moreover, before starting, he concentrated almost all his energy.

Therefore, at the moment when this huge oppressive force that seemed to come from between heaven and earth suddenly struck, Li Yue didn't make any mistakes in the re-engraving process because of this sudden oppressive force.

It's just that, although there has been no mistake due to pressure.

However, Li Yue could feel that every time he completes the next stroke according to the rune, he may make the surrounding oppression from heaven and earth become greater and more unbearable.

It seemed that if Li Yue continued to re-engrave it again in the shape of the strange rune, he would have to endure a stronger pressure than at this moment.

If Li Yue's mental power cannot withstand the huge oppression that follows.

There may be serious consequences of mental breakdown in an instant.

In the slightest, mental power is damaged, greatly weakening the intensity of mental power.

However, it is possible that Li Yue's whole body assembled by the whole mind may completely collapse in an instant.

"Sure enough, it is not easy to reproduce this kind of rune!"

"Possibly, it's like cultivating immortals needs to go through the baptism of heaven and earth, this kind of special cultivation system will also be punished by heaven and earth because of going against the heavens!"

"Maybe in the process of constructing this rune, you will have to withstand a special test from heaven and earth!"

"Only by passing the test of heaven and earth and getting the ultimate approval of heaven and earth can we successfully construct runes with special abilities."

At this moment, Li Yue could already guess that the unique cultivation system of this kind of rune might be the same as some kind of immortal cultivation system, and would have to withstand the test of heaven and earth.

Only by relying on strong perseverance or strong spiritual control to successfully pass the test from heaven and earth can we finally construct a strange rune that is recognized by heaven and earth and possesses special abilities and even rules.

Moreover, for people like Li Yue, who did not know anything about this special cultivation system before, the test from heaven and earth is more powerful and unbearable.

From the situation at this time, Li Yue could also guess.

Even at this moment, I have a powerful mental power comparable to the level of the multiverse, and after suffering such a powerful oppression from heaven and earth at this moment, I feel that my mental power is about to collapse.

So if it is the first time to learn and use this rune training system, wouldn't it be the moment when this rune was drawn, it was directly crushed to the bones by the huge oppression between heaven and earth?

And as long as some brains think about it, this is also completely impossible.

After all, no matter what kind of cultivation system, no matter how special this system is.

It is a process by which people or creatures can grow from weak to strong.

And everyone who starts to learn and practice starts from the weakest time But if a person is still very weak, he has to endure such a huge force that is unbearable.

I am afraid that no one can successfully practice this kind of cultivation method!

...

Of course, it is easy to explain why this happens.

Li Yue could easily understand why he suffered such a strong oppression from heaven and earth when he first started to draw such runes.

The main reason for this problem may not come from oneself.

It doesn't come from a certain defect in this kind of cultivation system.

It is from the rune that I drew at this time.

This rune, in its special cultivation system, should be an extremely advanced rune.

Such runes should not be advanced runes that beginners in this cultivation system can master.

At this time, Li Yue hadn't experienced the relatively low-level rune practice in this kind of practice system.

Rather, it directly draws and engraves this kind of rune, which is relatively advanced in its special cultivation system.

Naturally will bear more oppressive forces from heaven and earth.

Moreover, it is far more powerful than in this kind of cultivation system, a cultivator who can gradually practice to draw this kind of advanced rune will bear more powerful oppressive force.

Li Yue's situation at this time was like a saying in the saying, that he was a monk who became a monk halfway through.

And such a monk naturally has to go through more training than a true monk who has grown up in a temple since he was a child and has listened to the Dharma for many years!
