The Nine Shadows Divine Pupil burns the flames in the eyes, and the power gathers in the eyes, and over time, the feeling of color will become lighter and lighter, and eventually the entire heaven and earth will become black and white.

There is no way to recover.

This point, although the library is not mentioned, Zhang Hang is proficient in medical Taoism, and he knows all kinds of cultivation well, and it is easy to speculate backwards.

"Color blindness? What's that?"

Kui Sheng froze.

This term has never been heard of before.

"You don't know?"

was stunned for a moment, and then Zhang Hang suddenly became stunned.

This world is different from previous lives, and it is normal not to have the word "color blindness".

After hesitating for a moment, he explained: "Color blindness is not sensitive to color and cannot distinguish the type of color, just like my dress, what color do you see?"

"Ash!" said the Holy Tree.

"It's a little bluish, not gray!" Zhang shook his head.

It seems that the person in front of him has lost the ability to observe colors, and his robe, slightly light blue, and gray are completely different concepts.

"Pale blue?"

Frowning, Kui Sheng wondered in his heart...... Is this light blue?

How does it feel...... Not like it?

"If you can't see this, what about the rainbow, how many colors can you see?"

Zhang hung his palm and painted, and the true qi stirred in the air to form a colorful rainbow bridge.

"I can see a few colors, but ...... There are not seven of them, and many of them are so similar that you can't tell ......"

After looking at it carefully for a while, the more I looked at Kui Sheng, the more frightened I felt.

When he was a child, he could clearly distinguish seven colors when he looked at the rainbow, but now there are only three, and they are very blurry...... Could it be that it really became the pervert that the other party said...... Color blindness?

It can't really have anything to do with the Nine Shadows Divine Pupil left by the teacher, right?

For so many years, he had always believed in the exercises created by the teacher, and the young man in front of him had said so much evidence in a row, which made him can't help but have doubts.

"Is there a way to remedy it?"

After a pause for a long time, Kui Sheng couldn't help but ask.

"I've just seen the flaw, and I haven't found a remedy yet...... Zhang shook his head.

The library only gave a flaw, and he hadn't been exposed to it yet, a cultivation method similar to the pupil technique, so he couldn't add it.

"However, if you study slowly, you will always find it!"

As long as you give enough cheats and replenish them to the Heavenly Dao level, you should be able to solve this problem.

At the beginning, Qiu Wu Ancient Sage's Great Compassion Heavenly Clutch was also wrong, and it would also make people blind in their cultivation, and with the help of countless exercises, they would only modify it successfully, and now they will use it without any major problems.

"Oh......"

Nodding, Kui Sheng looked over: "This set of Nine Shadow Divine Pupils, do you cultivate?"

The power of the Eye of Reason, he knows very well, if he is blind, there is really nothing.

"I'll understand the exercises thoroughly, go back and study them, and then practice!" Zhang Hang nodded.

With such a powerful martial art, cultivation is inevitable, but the current exercises can make people blind, and they will definitely not be contacted.

Anyway, at present, the most important thing for him is not martial arts, but cultivation.

The cultivation is too low, even if he encounters Luo Ruoxi, there is no way.

"Well, yes, you have to study it well, these three days, you can learn from me, if there is anything you don't understand, ask carefully, after three days, if you leave this place, you won't have a chance!"

Kui Sheng nodded.

"Thank you, senior!"

In response, Zhang Hang sat cross-legged on the ground, his eyes looking at the words in the air, but in fact, his spirit was wandering in the sea, digesting and understanding the knowledge of the Nine Shadows Divine Pupil.

"The whole set of exercises, a total of more than 30 defects, each of which has great damage to the body......

I studied for an unknown amount of time, understood it all, rubbed my eyebrows, and hung my face helplessly.

It's not that he doesn't want to learn, but there are too many loopholes, so he can't talk about it as a person with perfect obsessive-compulsive disorder.

If you forcibly cultivate, you will really get more and more tired the more you practice, and eventually vomit out nauseously.

"What's the matter, if there's anything you don't understand, I can answer it for you!"

Seeing that he had stopped watching, Kui Sheng on one side looked over with a smile.

"It's a little confusing, but ...... You can't answer it, so forget it!"

Knowing that the other party had good intentions, he hesitated for a moment, and Zhang Xuan finally shook his head.

It's not that he underestimates the other party, his own problems, even the ancient saints of Bu Shang can't solve them, otherwise, he won't cultivate to the point of blindness.

"Can't solve it?" frowning, Kui Sheng was slightly displeased: "This set of exercises, I have been immersed in it for hundreds of years, and I have cultivated to the second level, as long as the problem of cultivation is solved, it will definitely be solved!"

The person in front of him, although his eyesight is very strong, and he can see the biggest flaw of the Nine Shadows Divine Pupil at a glance, but this set of exercises, he has studied it for so many years, coupled with his own profound cultivation, it is definitely not comparable to the other party.

"Can it be solved?"

Seeing his confident face, Zhang Hang looked over and smiled lightly: "Well, I just have a few questions, but I haven't figured them out, and I hope my seniors will answer them! The gods and demons in their eyes can give people shock, what kind of forms do gods and demons have? What are the specific appearances? If it is just random imagination and speculation, how can it produce results?"

"This ......"

Kui Sheng was stunned.

The so-called gods and demons are indeed unseen.

When he first imagined it, he just tried to imagine the appearance of the killing land in his heart, replacing the gods and demons with murderous aura to give people a shock.

Just as he was about to say his cultivation method, he heard the young man continue to speak: "If you just visualize killing, the killing qi enters the sea of knowledge, and you have killing intent in your eyes, what is the difference between you and the alien spirit clansmen? Gods and demons are majesty, not killing, if you really want to do this, you are tantamount to going astray from the path of cultivation!"

His body shook, and his face turned pale.

When contemplating killing, he did have a period of time when it was difficult to control the killing intent in his body, so he went to the cave and killed the alien people.

When the other party said this, it was simply against the identity of a famous teacher and the principle of being a man.

"Second question!"

Seeing that he couldn't answer, Zhang Xuan continued: "Attacking others with his eyes relies on soul impact, which involves a lot of lines, I just looked at it, and the eighty-seventh of them can absorb the spiritual power of the other party, the purpose is to lock the Yuan Shen and attack better, but ...... If someone predicts it in advance and takes the opportunity to attack, will this move collapse directly, or even be counterattacked by the force? Even if you don't realize it, the Yuan Shen is far superior to you, and if you force an attack, it will also be damaged!"

The saint was dumbfounded and speechless.

What the other party said was another flaw of the [Gods and Demons in the Eyes], the teacher had told him at the beginning, even if he was a strong man like Bushang Gusheng, he couldn't make up for it.

However, although this is a flaw, when fighting, the confrontation is fleeting, and few people can detect it and fight back.

Even if it's a flaw, it's not too important.

It's just that...... I really don't know how to answer the question suddenly.

"The third, King Kong is angry, the tiger is subdued, the fire is used to refine the eyes, the cold ice is used to refine the pupils, the cold and heat alternate, the ice and cold are blended, and the eyes give birth to Taiji, which is in line with the nature of heaven and earth, but ...... The way of heaven is one, all things in a lifetime, two opposing powers, have been circulating in the eyes for a long time, although they can greatly increase the power of the runes, and the lines in the eyes of the clear reason are more brilliant, but they will also suppress their other soul powers, like a seal, making their original primordial spirit attacks weak......"

"Fourth Question ......"

Zhang Hang asked one by one.

Every time he asked, Kui Sheng's face turned a little whiter, more than ten in a row, and his figure became more and more faint, and he would fall down at any time.

It's not surprise anymore, it's fear.

The Nine Shadows Divine Pupil, although it was created by the teacher, also has flaws, according to the normal situation, the flaws are not concealed, as long as they are used carefully, there will not be too many problems, and even if it is him, he will ignore these.

The person in front of him, who only looked at it for a while, actually said the loopholes that appeared in it, one by one, if it was not learning, but the enemy, just by knowing this, he could easily break his stunt, and blinded his eyes in one move!

Cold sweat ran down his neck.

Nine Shadow God Pupil, since learning, has always felt that it is an invincible stunt in the world, fighting against people, as long as it is used, a hundred battles will be won!

Hearing the other party say this, I realized that he hadn't met a real master, and if he really wanted to meet, whether his eyes could be kept or not was still unknown.

Wanderers who drown, who attack with their eyes, will die on it sooner or later.

"In just a moment, I saw so many flaws...... I'm still thinking of giving him some pointers......"

His body stiffened, unable to speak, and Kui Sheng was depressed and wanted to explode.

Just now he swore that he wanted to give advice to others, but he couldn't answer any of the questions asked by the other party......

I only feel the pain of my face, and I can't bear it at any time.

"This is the thirteenth ...... So, let's talk about this today, senior, can you think of how to answer?"

The young man's voice continued to sound, with comfort in his tone: "Don't be nervous, think slowly, there is time, anyway, there are more than two days...... It's really not good, I'll sleep for a while, and when you think about it, call me and help me finish answering, and then I'll continue to ask the next questions!"

"Ahem......"

The corners of his mouth twitched, and Kui Sheng shook twice.

In the past, he used to assess the juniors and give the other party an answer, how to ...... Now it's the same answer, but it's the same as the other party testing himself?

The most important thing is...... It's okay if these questions can be answered, but they can't be answered at all!

Not to mention him, even if he is a teacher for many years, if he can answer the question, he will definitely revise the method again......

The teacher couldn't answer it, so he thought about answering...... Not to mention two days, you can't do it in two years!

left his thoughts and assessed future generations, but now he is stumped by future generations......

Where did the freak come from? So powerful?

After thinking about it for a long time, I found that I couldn't answer any of these questions, so I had to look at the young man helplessly, but I saw that this guy was lying on the ground and already asleep, the corners of his mouth did not stop saliva, I don't know what he dreamed of, and his face was full of smiles.

"This ...... Are you the first hall master, or am I?"

The corners of his mouth twitched, and his eyes darkened, and he only felt a burst of depression, and his whole mind kept shaking, as if he couldn't bear it.
