In the depths of the night, a figure with a dazzling arc of lightning flashed around the practice field next to the Uchiha clan, emitting a short whistling sound of breaking wind.

There is no doubt that it is no one else who is still cultivating hard in the silence of the night, it is Sasuke, who was defeated by Naruto during the day.

Whew...

At this time, Sasuke, who was churning in the air, shot a round of shuriken, and then pulled his hands violently, and through the pull of the wire, the shuriken that flew out changed the trajectory, and hit several targets hidden behind wooden stakes or stones impartially.

After landing, Sasuke gasped heavily, and there was not the slightest joy on his face that he had hit the target.

"Ahh

Suddenly, he covered his eyes in pain.

Since the big battle with Xiao a week ago, he now has a faint stinging pain coming from the chakra whenever he uses it, and after today's battle with Naruto, he found that this stinging has a tendency to intensify.

In addition, he also noticed that his vision, which had improved slightly, began to deteriorate again, with blurring and ghosting.

The regression of his eyesight made Sasuke irritable and panicked, and he couldn't help but think of the fight with Naruto during the day, and the thought of his defeat again in front of everyone's eyes, and he was suddenly ashamed and angry.

Boom...

A punch slammed into the big tree beside him, and Sasuke looked hideous: "Damn, I used the power of the Kaleidoscope Writing Wheel Eye, and I still lost to Naruto!" ”

At this moment, there was a sound of gentle footsteps not far away, Sasuke looked over, and found that it was not someone else who was walking towards the training ground, it was his brother Itachi, so he quickly suppressed the stinging sensation and put on a casual appearance.

Itachi, who had come to the practice range, took a closer look at Sasuke and found that Sasuke's face could still see some of the bruises left by the day's fight with Naruto.

Immediately, Itachi asked, "It's so late, why don't you rest?" ”

As if trying to hide the bruising on his face, Sasuke twisted his head to the side: "I just can't sleep!" ”

Itachi was silent for a moment and said, "Is there something wrong with the Kaleidoscope Writing Wheel Eye?" ”

Sasuke immediately said stiffly: "No, my kaleidoscope writing wheel eye is very good!" ”

Itachi said, "You're lying. ”

Sasuke was a little angry: "You don't have a kaleidoscope writing wheel eye, how can you know if there is a problem with my eyes!" ”

Itachi didn't say much, but slowly opened his kaleidoscope writing wheel.

"It's... This is?! ”

Staring at the kaleidoscope writing wheel in Itachi's eye socket, Sasuke was dumbfounded.

Itachi said indifferently: "The kaleidoscope writing wheel eye is both a gift of fate and a curse of fate, from the moment you open your eyes, blindness is the inevitable result." ”

Sasuke was still immersed in the shock that Itachi also had a kaleidoscope writing wheel eye, and said in a daze, "Blind? ”

Itachi asked, "Your eyesight must be starting to decline, right?" ”

Sasuke was shocked: "Brother, how do you know? ”

He has been trying his best to hide the secret of his declining eyesight, so he was surprised to be revealed by Itachi's words at this time.

Itachi's face was calm: "Because this phenomenon is not an isolated case, every Uchiha person who awakens the kaleidoscope writing wheel eye will face a decline in eyesight after the loss of pupil power. ”

Sasuke nervously asked, "Will I be blind then?" ”

Itachi nodded: "Under normal circumstances, as long as you don't continue to lose the pupil power of the Kaleidoscope Writing Wheel Eye, then your vision can barely be maintained, but if you continue to consume the pupil power of the Kaleidoscope Writing Wheel Eye, blindness is the inevitable end." ”

"What!?" Stunned for a moment, Sasuke said: "How can this be, if I can't use the Kaleidoscope Writing Wheel Eye anymore, then what is the point of me awakening the Kaleidoscope Writing Wheel Eye?" ”

Itachi sighed softly: "You always refuse to be obedient, I have already reminded you, you must be cautious in using the kaleidoscope to write wheels, but you are doing your own thing." ”

Sasuke staggered two steps in despair, and muttered to himself, "I'm not Naruto's opponent with the Kaleidoscope Writing Wheel, if I can't use the Kaleidoscope to write the Wheel, then I won't be able to catch up with Naruto for the rest of my life?" ”

Looking at Sasuke, who was lost in his soul, Itachi didn't make a sound, just stood quietly aside.

The reason why he didn't explain this to Sasuke at the beginning, but gave a vague hint was to give Sasuke an unforgettable lesson, so that Sasuke could personally experience the anxiety and panic of vision loss, so that Sasuke could cherish the pupil power of the Kaleidoscope Writing Wheel Eye from the bottom of his heart, and treat the power brought by the Kaleidoscope Writing Wheel Eye with a more cautious and humble attitude.

And not as it is now, impetuous, arrogant, and unscrupulous squandering pupil power like an upstart.

Because in his opinion, it is the ninja who controls the pupil power, not the hitomi power that controls the ninja, in his heart, the Hyuga mirror is a model in this regard, obviously superior in strength, but still gentle and humble.

This is one of the reasons why he regarded Hinata as an idol.

Of course, to teach Sasuke this lesson, it is also because of their father's pair of kaleidoscope writing wheel eyes guarantee, if it were not for this opportunity to fuse the eternal kaleidoscope writing wheel eyes, he would not have watched Sasuke waste the pupil power of the kaleidoscope writing wheel eyes so much, after all, it is too luxurious to use the pupil power of the irreparable kaleidoscope writing wheel eyes to buy a lesson.

"Brother, there must be a way to save it, right?"

Sasuke wasn't stupid, he reacted quickly, if the pupil power of the Kaleidoscope Writing Wheel Eye couldn't recover after it was depleted, then his brother would definitely not watch him make such an irreparable mistake.

After a deep sigh, Itachi said, "There is indeed a way to escape the curse of blindness. ”

Sasuke asked eagerly, "What is the method?" ”

Itachi stretched out two fingers: "The first is to transplant the cells of the first generation, and use the high-intensity Yang Dun Chakra in the first generation cells to fuse with our own Yin Dun Chakra to produce the power of Yin and Yang in one, and then use this power to nourish Yin and Yang to supplement the kaleidoscope writing wheel eye pupil power that we cannot replenish ourselves." ”

"Transplanting primary cells?"

Sasuke remembered that in the previous battle with the Akatsuki organization, Shisui had used the 'Mu Dun' ninjutsu on the 'Hungry Ghost Dao' Kirabi, and immediately understood that Shisui should have used this method to replenish the pupil power of the Kaleidoscope Writing Wheel Eye.

Itachi's tone gradually deepened: "But this method is very dangerous, with your current will, nine deaths!" ”

After being vetoed by Itachi, Sasuke panicked: "That... What about the second method? ”

Itachi said calmly: "The second method is to fuse the kaleidoscope writing wheel eye of your loved one, and use the pupil power of two pairs of kaleidoscope writing wheel eyes to impact the extreme of yin retreat, and open the eternal kaleidoscope writing wheel eye that will never be blinded." ”

Sasuke was stunned for a moment: "The kaleidoscope writing wheel eye that fuses with the dearest?!" ”
