140 Chapter 1298: Sage Kui’s Dilemma (1/2)

Due to the inferno burning within one's eyes, those who practiced the Divine Eyes of the Ninth Netherworld would find their sensitivity toward colors fading as time passed, and eventually, the entire world would appear to be nothing but black and white to them.

Due to the nature of the injury, it was an irreversible symptom. There was no way to recover from it.

This was not listed in the flaws in the Library of Heaven's Path, but through Zhang Xuan's deep understanding of the Way of Medicine and cultivation, he could still deduce this much from working backward.

”Color blindness? What's that?” Sage Kui was stunned by the foreign term.

He had never heard that terminology from anyone's mouth before.

”You don't know what it is?” Zhang Xuan was startled for a moment before realization struck him.

Due to the difference in worlds, it was indeed possible that the notion of color blindness was not as prevalent or common in this world.

So, Zhang Xuan pondered for a moment to decide how he should explain the concept. ”Color blindness refers to a lack of sensitivity of one's eyes in perceiving different colors. Take my clothes for example, what's the color that you see?”

”Gray,” Sage Kui replied.

”It's light-blue, not gray,” Zhang Xuan stated with a shake of his head.

”Light-blue?” Sage Kui frowned.

Is this supposed to be what light-blue looks like? Why doesn't it seem to be the case?

”Let me ask you a different question instead. How many colors are there in a rainbow?”

While saying those words, Zhang Xuan waved his hand and created a rainbow bridge of seven colors in the sky.

”I can discern a couple of colors from it, but… there doesn't seem to be seven colors in the rainbow you have created. Furthermore, most of the colors are of similar tones, so I can't really say for sure either…” Staring at the rainbow intently, Sage Kui felt a ripple of shock striking his mind.

He had seen plenty of rainbows when he was younger, and he could accurately distinguish seven colors from them. But now, he could only identify three colors in total, and the difference between the three was very vague. Could he really have been suffering from color blindness, just as the other party had said?

Was this really the side effect from practicing the Divine Eyes of the Ninth Netherworld that his teacher had left behind?

For so many years, he had harbored absolute faith toward the optic art that his teacher had created. However, under the persuasive and logical analysis of the young man before him, he could not help but begin doubting.

”Then… is there a way to resolve the problem?” Sage Kui asked.

”So far, I only managed to analyze the flaws in the optic art. I haven't really found a way to resolve them yet…” Zhang Xuan shook his head.

The Library of Heaven's Path would only reflect the flaws of techniques, and Zhang Xuan had not come into contact with any optic art manuals before, so he could not compile anything with the Divine Eyes of the Ninth Netherworld to perfect it.

”However, since we have identified the problem, it will only be a matter of time before a solution is found!”

As long as Zhang Xuan could find sufficient optic art manuals to perfect the Divine Eyes of the Ninth Netherworld, those problems would be resolved as well.

Back then, there had also been many faults with Ancient Sage Qiu Wu's Heavenly Demon Great Sorrow Palm, and cultivation of the technique could have caused one to go blind, too. Nevertheless, through compiling it with many other cultivation techniques, he had resolved that problem.

”Let's hope so…” Sage Kui nodded. ”So, will you still be cultivating the Divine Eyes of the Ninth Netherworld?”

Sage Kui knew how powerful the Eye of Insight was as well, and it would indeed a pity to go blind as a result of cultivating an optic art.

”I think I'll hold off cultivating the technique for the time being. I'll try to resolve the current problems before cultivating it,” Zhang Xuan replied.

Despite its flaws, the Divine Eyes of the Ninth Netherworld was still an extremely formidable battle technique. He would have to find some way to access optic art manuals so as to compile them together with it and perfect it.

In any case, there was no rush for the time being. What he was lacking in the most at the moment was not battle techniques but his cultivation.

If his cultivation was too low, no matter how many formidable battle techniques he had, he would still be unable to faze the Zhang Clan and the Luo Clan.

”Un, that would be good, too. For the next three days, you should try to gain a complete understanding of the Divine Eyes of the Ninth Netherworld. If there's anything that you are unable to comprehend, feel free to ask me. You won't have any more opportunities to clarify your doubts once you leave this land in three days!” Sage Kui nodded.

”Thank you, elder!” Zhang Xuan replied before sitting on the ground.

While he appeared to be staring at the words in the air, his consciousness was immersed within his mind as he tried to fully grasp everything concerning the Divine Eyes of the Ninth Netherworld.

There are more than thirty flaws to the optic art all in all, and every single one of them poses great damage to the body.

After a moment of studying the optic art, Zhang Xuan rubbed his glabella helplessly.

It was not that he did not want to cultivate the technique, but there were simply too many flaws in it! How could a perfectionist like him possibly swallow something like this?

If he forced himself to cultivate it, he might very well die from repulsion before anything else.

Seeing that Zhang Xuan had paused on the spot for some time now, Sage Kui asked with a kind smile, ”How is it? Is there anything concerning the Divine Eyes of the Ninth Netherworld that confuses you? I can address your doubts here!”

Knowing that Sage Kui was asking out of goodwill, Zhang Xuan hesitated for a moment before shaking his head. ”There are quite a few aspects of the optic art that confuse me, but it's fine. I don't think that you'll be able to address them either.”

It was not that he was underestimating Sage Kui, but it was likely that even Ancient Sage Bo Shang himself would have been unable to address his doubts! Otherwise, there was no way he would have ended up blinding himself.

”You are saying that I won't be able to address your doubts?” Sage Kui frowned in displeasure. ”I've spent several centuries cultivating the Divine Eyes of the Ninth Netherworld, even reaching the second realm of it. As long as it's a problem regarding its cultivation, I'll surely be able to answer it!”

He knew that the young man before him possessed an exceptional eye of discernment, being able to notice such a major flaw in the optic art with just one look. Nevertheless, he had still cultivated the technique for many years now, and not to mention, he was also a powerful cultivator. He was confident that with his deep understanding of the battle technique, he would be able to address any questions that the young man could come up with.
