Konoha Scientific Ninja R&D Center, Biochemical Research Experimental Area, an operating room.

Sasuke got up from the operating table and opened his eyes.

His pupils changed again, evolving a new kaleidoscope pattern, much like the silhouette of an electron revolving around the nucleus!

As soon as the eyes opened, the irrepressible powerful pupil power exploded, showing a power that surpassed any previous writing wheel eye, and the pupil power emitted seemed endless!

"This ......," Sasuke muttered, "is it the power of the Eternal Kaleidoscope Writing Wheel?" ”

Naruto was wearing a white lab coat and standing right next to the operating table, and it was he who gave Sasuke the transplant.

"I see, the secret of the Eternal Kaleidoscope Writing Wheel Eye has finally been revealed......"

Naruto touched his chin and pondered, "A pair of dear brothers, both with kaleidoscope writing wheels, one of them transplanted the other's kaleidoscope, and it is not certain whether the donor must die......"

Naruto's development of the Sharingan also stopped at the kaleidoscope, but he found clues in Itachi's suicide note, and finally helped Sasuke get promoted again.

In the history of the ninja world, only Madara Uchiha transplanted the kaleidoscope writing wheel eye of his dead younger brother Izuna to obtain the eternal kaleidoscope writing wheel eye.

Sasuke and Itachi were the second success story, both of which came with the death of the donor, and Naruto was not yet sure if the brothers could transplant each other's eyes, thus achieving the result of two pairs of eternal kaleidoscope writing wheels at the same time.

"How did Itachi know this secret? Could it really be that there really is an Uchiha Secret Scroll? ”

Naruto muttered, "What the hell is this?" Can you try mass production? Telepathy between blood brothers? But it's not twins. Homologous gene complementation? Reverse transcription of homologous genes? Or is it quantum entanglement? Cognate brainwave synchronization? Homologous cell resonance? Cognate chakra resonance? ”

"Stop chattering, Naruto!" Sasuke rubbed his forehead and said, "You muttered that I have a headache, take care of my mood." ”

"I'm sorry, I'm sorry!"

Naruto scratched his head in embarrassment, and then realized that Sasuke had just lost his brother and had received a valuable relic from his brother.

Quickly changing his way of thinking and detaching himself from his identity as a researcher, Naruto solemnly said, "Uchiha Itachi is a difficult person to evaluate, but there is no doubt that he is a very competent older brother. ”

Sasuke looked sad and whispered with mixed feelings: "Instead of giving me a pair of eyes like this, it is better to let me accompany him on the last journey......"

"He actually has his considerations in doing this." Naruto sighed, "I can probably guess what he thinks." ”

Sasuke pressed Naruto's shoulder and asked eagerly, "Tell me what the hell he thinks!" ”

"Kaleidoscope Sharingan is actually a curse of the Uchiha clan."

Naruto said, "The Uchiha people who have turned on the kaleidoscope will be blind sooner or later. When the pupil power is depleted and the kaleidoscope is continued to be forcibly used, blindness will occur. Itachi knew this very well, his eyesight was already very poor, and he was only one step away from becoming blind. ”

"Did he leave his eyes to me because he was afraid that I would follow in his footsteps and consume too much pupil power and go blind?" Sasuke muttered, "Even if he wants to transplant my eyes, can't he wait any longer...... Why ...... in such a hurry?"

"Alas......"

Naruto sighed deeply and said, "I shouldn't have told you, but I felt the need for you to know." In fact, when Itachi came to me to report on his work, I mentioned to him that I had a way to treat his terminal illness, which would at least extend his life by three to five years. But he refused. ”

Sasuke was stunned.

"Now I can probably guess what he thinks, in fact, he has already made a decision, no matter what method is used, he just wants to die at your hands."

Naruto sighed, "In Itachi's opinion, only if you kill him can you truly comprehend the power of the Kaleidoscope Sharingan. The fate of the Uchiha clan is to love and kill each other. If you refuse to do it, he will cut your abdomen, force you to make a mistake with your sword, and help him get free. When you wielded that sword, you were killing him, but you forgave him, out of love for him. This is in line with the Uchiha clan's fate of loving but killing each other, thus passing on his pupil power to you, laying the foundation for your promotion to the Eternal Kaleidoscope Writing Wheel. ”

"Why did he arrange all this for me! It's not what I want! ”

Sasuke lowered his head and roared in pain.

Sasuke once had the idea that he would never follow the path arranged by his brother, and that he would definitely improve his strength in his own way.

Unexpectedly, Itachi had already seen through his stupid younger brother and made such a cruel plan!

"It's just my speculation." Naruto smiled bitterly, "Maybe it's because I spent the belly of a gentleman with the heart of a villain, maybe Itachi was really tired and sincerely repented, so he ended his life with 'Thoughtless Belly'." Or, a combination of both, both liberates you and fulfills you. ”

"Why can't you say it frankly......" Sasuke lowered his head and whispered, "Do this to me again and again!" Am I really that stupid in his eyes? ”

Naruto didn't say anything, he was silent for a moment and felt that this was not good, which was equivalent to acquiescing to Sasuke's words, and hurriedly said: "Sasuke, Itachi is different from me, I am a friend to be frank with you, and he is your elder, and he treats you with a kind of condescension unique to elders." The eldest brother is like a father, and his relationship with you is more like a father and son than a brother. Even if you don't like the way he treats you, don't blame him, because he thinks about you, and you can't blame someone who truly loves you. ”

Naruto said in a sighing tone, "He received treatment, even if he could extend his life by a few years, because his pupil power had long been exhausted, and his eyes were nearly blind, and he couldn't help Konoha survive the crisis of Madara Uchiha." Even if he drags a broken sick body, he always cares about Konoha's fate and your future.

He wants you to be the hero who saves Konoha and reverses the perception of the Uchiha as traitors. Only in this way can the descendants of the Uchiha live in the sun with dignity and integrity, and the Uchiha clan can be revived. ”

Sasuke fell into the memory, his brother will always be like in his childhood memories, taking care of his younger brother who is not angry, and always putting the heaviest burden on his shoulders and sheltering his younger brother from the wind and rain.

No one knows more than Uchiha Itachi how fierce Madara Uchiha's counterattack is, and no one hates Madara Uchiha more than Uchiha Itachi, the initiator of the tragic fate of the rebels of the Uchiha clan!

Uchiha Itachi was worried that Konoha's current strength might not be able to resist, so he used the most ruthless and painful way to achieve Sasuke's eternal kaleidoscope writing wheel, leaving the corpse as the material for the reincarnation of the filthy earth, and in the future, he will use the filthy earth reincarnation body to fight against Madara Uchiha with his younger brother, and the brothers will work together to change the fate of the Uchiha clan!
