Zhang Xuan's habitual action was the first time he saw the book, which was included in the Heavenly Dao Library, so what he was looking at now was not the content that appeared in the air, but the books in the sea of knowledge.

Fortunately, when the real formula flowed through my mind, I immediately noticed that something was wrong.

"What's wrong?"

Kui Sheng looked over.

This set of recipes was created by his teacher himself, extremely profound, and all the geniuses who had the eyes of reason saw it, all immersed in it, unable to extricate themselves, the one in front of him, frowned directly, and said "There is a problem", what does it mean?

"This ......"

Zhang Xuan turned his head and looked at the holy mind in front of him: "Senior, I want to ask, among the hall masters of the past dynasties, is there anyone who is blind?"

"Blind?"

I don't know what his intention was in asking this, Kui Sheng frowned: "My idea is only responsible for guiding and testing the selection of the master of the hall, and I don't know what happens to the juniors." ”

The time of his death, as early as tens of thousands of years ago, the hall masters of the past dynasties were all juniors, unless a genius with a rational eye entered, he could be sober, as for whether these juniors were blind, it was not clear.

"That'...... Take the liberty of asking, how are the eyes of the ancient saint of Bu Shang?" Seeing that he didn't know, Zhang Xuan hesitated a little and asked again.

Soon after the teacher founded the Holy Son's Temple, he left directly...... His eyes are indeed blind!"

Kui Sheng paused, "However, if you go and find a way to recover, you should be able to recover ......"

"Recovery?" Zhang Xuan smiled bitterly: "I think it's extremely difficult, and it's not even possible!"

"Why?" said Kui Sheng, looking at him suspiciously.

There are many deeds and books about the ancient saints of Bushang in the Holy Son's Temple, but they are all very bright, and few people know about the blindness, so there is no external transmission, how can the person in front of him know?

And to say directly, it is impossible to recover?

"The reason is in this set of Nine Shadow Divine Pupils!" Zhang Xuan sighed.

"This set of pupil techniques is to exert the power of the eye of reason and tap the potential of people, which belongs to the top of the first-class exercises, but ...... Every time you run the formation, it will cause a lot of damage to your eyes, and over time, it will make people blind, and it will be difficult to treat them!"

The first defect reported by the library is that it will make people look at the mission and cannot be cured.

Whether it is an ordinary person or a cultivator, the potential is always fixed, using the formation pattern to stimulate the power in the eyes, and even derive the martial art of killing...... It is extremely harmful to the eyes, and some are even permanent.

No matter how clever the elixir is, no matter how clever the means, it will have no effect.

Just like some peak athletes in previous lives, the life span is generally not too long, because when they are young, they will fully use the potential of their bodies, and when they get old, there will be more and more injuries and diseases, and it will be difficult to enjoy ordinary life in the end.

Jiuxiao Divine Pupil, not only consumes the eyes, but also the optic nerve in the mind, all consumes, the eyes can be replaced, can be treated with medication, once the nerve dies, it is like the end of life, and it is difficult to have any other way.

It was precisely because he saw this that he felt that although this set of exercises was very good, there was a big problem.

It can even be said to be a fatal flaw!

The eye of reason is a gift from God, with extremely strong efficacy, once blind, it is equal to the loss of the strongest means, not to mention strength, even if it is mentality, I am afraid it will be a heavy setback, difficult to recover.

Hearing this, seeing the young man sighing helplessly, Kui Sheng frowned, and his face showed displeasure: "I have practiced this set of exercises for hundreds of years, and I have not noticed that it has caused damage to my eyes?

It's not that he doesn't believe it, but he has also cultivated for a short time, and his eyes are still intact and he hasn't experienced any discomfort.

Wouldn't it be too alarmist, too exaggerated?

Besides, who is the teacher?

Master Confucius's personal disciple, one of the top ten sages, immersed in martial arts for a lifetime, how can there be a problem that will make people blind?

If you really think like this, aren't you doubting the teacher?

Even if you doubt it, it's not your little Yuan Shen Realm guy, you should do it!

"Whether it's alarmist or not, I'll say it carefully, and you'll know...... The predecessors have cultivated for hundreds of years, if you are not mistaken, this set of Nine Shadow Divine Pupils should not have reached the third level, right?"

Knowing that the other party would say this, Zhang Hang looked over.

"Yes!"

Kui Sheng nodded.

His cultivation is far inferior to that of a teacher, let alone the third level, even if it is the second level, he has not reached the peak.

"If you read it right, when you left this thought, you should have just cultivated the Nine Shadows Divine Pupil to the early stage of the second level, using the flame to train the eyes, and the cold ice quenched the pupil......s! If you really fight, there is still some heat left, and the second King Kong is angry, and it shouldn't be able to be used completely!"

Eyelids raised, open hanging.

The Nine Shadow Divine Pupils, the first weight of the eyes of the gods and demons, the second level, the angry eyes of King Kong, at a glance, the flames burn, burn the heavens and the earth, all the power is exerted, and the hell can be burned through in an instant.

If the first is a mental attack, the second is a real physical attack.

If the strength is not strong, it will not be able to resist at all, it will be wiped out in an instant, even if it exceeds its own, it will be embarrassed, and it will be difficult to exert its strength.

The most important thing is that the attack can be launched at will, without any tricks, as far as the eye can see, it is an attack...... It's impossible to prevent it, and there's no way to resist it.

Because of this, this set of pupil skills is so famous, and the hall master of the Holy Son Hall is also famous, and his status is not weaker than that of family masters such as the Zhang family.

However, this set of martial arts is very powerful, but it is also extremely troublesome to cultivate, first to train the eyes with flames, quench the pupils with ice, and then go through countless tempering, if you are not careful, you may lose your previous achievements and destroy your strength.

The person in front of him, although he didn't use the pupil technique, with his understanding of the pupil technique, should have reached the second realm.

"You...... How do you know?"

Kui Sheng was full of surprise.

What the other party said was exactly the same, when he left his thoughts, he had just cultivated the Nine Shadows Divine Pupil to the second level, and he didn't know how far away it was from the third level.

"Although you are just a thought now, there is a flame burning in your pupils, although it is not prosperous, but it has the power to burn everything, which is the same as the second King Kong angry eyes, so you can easily see it!"

Taking a step forward, Zhang Hang circled along the other party and said lightly.

Putting the cheats in the air into the library, it's almost the same, integrating all the knowledge, although the other party is just an idea, but with his eyesight, it's not too difficult to see this.

"What do you mean...... Have you finished reading all of the second exercises?"

Kui Sheng's body was shocked, and his eyes widened.

He had just taken out the secret book of the Nine Shadows Divine Pupil, and he saw the end from the other party, but it only took a few breaths...... Now that I have directly said the characteristics of the second one, is it possible that I have read them all and memorized them?

This set of exercises is full of hundreds of thousands of words, and it takes a lot of effort just to memorize it.

Therefore, he was also praised by his teacher, saying that he was talented and intelligent, and his memory was amazing......

How is it possible that this guy only took a few breaths and wrote them down?

"This set of exercises is easy to memorize, there is nothing to write down, the most important thing is how to understand and practice. ”

Zhang Xuan shook his head, not happy because of the other party's shock, but with regret: "You have cultivated to the second level of King Kong angry eyes, if you don't guess wrong, red spots will appear in your eyes from time to time, a slight itchy feeling, and tears will appear when you encounter a strong wind, and the most important thing is that after running the flames, there will be a short period of blindness, not for a long time, about three breaths ......"

"I wonder if it's correct?"

"You ......" Kui Sheng couldn't believe it.

He did have this situation when he left his thoughts, but he was cultivating at the time, thinking that it was caused by the flames, and he didn't pay attention to it, could it be that there was really something wrong with the cultivation exercises?

When he reached the second level, the teacher had already left, and he couldn't ask anyone, so this set of tricks was basically cultivated by himself.

I just practiced, I fought with people, and I did have a short period of blindness, about three breaths, and I thought it might be caused by detachment at the time, but it was the same as what the other party said...... Is there a problem in the exercises?

"King Kong's eyes are angry, his eyes turn into a sea of red lotus fire, and when he is completed, the karmic fire is all over the sky, burning all the dirt things, the power is indeed powerful, but ...... The overdraft of the spirit is also very large, and after using it, the nerves that control the vision will become old and lose their lifespan! It's like a formation disk, which can be used ten times, and every time it is used, some of it will be consumed, and after ten times, no matter how strong the array mage is, it can't be repaired, so it can only be invalidated!"

Shaking his head, Zhang Hang regretted: "When you pay attention to it, although you have just reached this realm, there are hidden dangers, there are more bloodshot eyes, and there is a slight redness when you look carefully, and the most important thing is that you will often have insomnia!"

"You know...... Will I have insomnia?"

Kui Sheng's ghost-like expression.

In order to achieve this state of cultivation, although he can use cultivation instead of sleep, if he sleeps once in a while, it will be extremely relaxing for his mind and body.

Because of this, when night comes, they occasionally sleep.

Back then, the teacher had just left, and he was in charge of an academy by himself, and the pressure was too great, and he hadn't rested much, and he couldn't sleep if he wanted to, thinking that it was because his spirit was too tight, could it be related to this Nine Ghost God Pupil?

I vaguely remember...... The teacher also seems to have insomnia and stays up all night.

"It is normal for the nerves to be damaged, to be hit by the sea of consciousness, to have insomnia, and with the deepening of cultivation, it will also cause mental weakness, which will lead to forgetfulness, memory decay, and most importantly, ...... It will become more and more insensitive to color, and eventually the colorful colors of heaven and earth will become black and white in the eyes, and the others will never appear again......"

Speaking of this, Zhang hovered for a moment, let out a long sigh, and his face was full of sympathy: "That is, the legendary ...... Color blind!"

"If that's right, you should be!"
