Yeah, who knows.
Maybe everything about Rinnegan is just a legend without roots. Sharingan has no way to evolve. Its apex is the pair that Uchiha Madara once owned.
Being able to use the pupil technique to transform into a chakra-filled giant like Wood Golem, which is as huge as my grandfather, may be the final outcome and end.
If there really was such a pupil technique as resurrection, then Sage of Six Paths would not be turned into a legend now.
Tsunade sighed heavily, took a deep breath, looked at the apprentice Shizune beside him, and nodded gently.
"Teacher... have you really thought about it?" Shizune's voice was very soft, with a hint of trembling.
"Perform eye replacement surgery for me, Shizune."
Tsunade's voice was very soft. She was lying flat on the operating table. The shadowless light above her head was very dazzling, making her involuntarily narrow her orange eyes.
"Master...".Shizune said softly.
Shizune beside him was holding a sterilized scalpel, and the test tubes containing the two Sharingan were lying quietly on the operating table.
Shizune held the scalpel with an imperceptible tremor.
This is not the first time she has treated or performed surgery on others, nor is it the first time she has stood in front of the operating table. The surgery she is about to perform is extremely simple. It is not a lung or kidney transplant, but an eye transplant.
Dig out the eyes, insert the two Sharingans that have been prepared long ago, and use Mystical Palm Techniques to connect the nerves, and that's it.
But the person who underwent the surgery was his master. She was the best Medical Ninja in the whole Shinobi World, and she was also a powerful ninja. She was the princess of Konoha and Land of Fire, and he wanted to dig out her two familiar orange eyes...
"Shizune, don't hesitate. I have already checked. There is no seal or anything like that on that pair of Sharingan. It is just a pair of ordinary Sharingan."
"I have operated on those Uchihas on the battlefield before, and there is no difference between them."
"You only need to cut off the nerves in my eyes, remove them, preserve them in culture fluid, and then take out Sharingan and place them in my eye sockets. The nerves on these two Sharingans are well preserved. You only need to use Mystical Palm Techniques to connect them to my nerves, and that's it."
Tsunade looked at Shizune who was reluctant to take action and began to urge him.
Accepting these eyes Sharingan, she thought for a long time whether to replace them for herself. She thought for a long time again and finally decided to have surgery.
Shizune had been asking her before whether what the majestic boss said was true or not, and also asked her what the secrets of Sharingan were, and what Rinnegan looked like.
She looked at Shizune's condescending look, and involuntarily closed her hands in front of her chest, tightly holding the necklace that belonged to her grandfather.
A perfect resurrection? Oh, I'm just curious, what would it be like to have Sharingan?
She opened her eyes and watched Shizune's chakra-attached scalpel approach her eyes little by little, followed by a sharp pain, and her vision turned dark.
She heard the sound of the test tube being opened and closed, and then she felt cold liquid dripping on her painful area, and cold soft balls falling into her empty eye sockets.
Then the coldness was replaced by warmth, which was Shizune's chakra. She gradually felt a beam of light, a dazzling light flashing past. In front of the light, Shizune's anxious face was blocked.
"Lady Tsunade, can you see it?" Shizune looked at the familiar face and the unfamiliar black pupils on this face, and shook his hand.
"Stop shaking, Shizune, you'll faint if you shake any more!" Tsunade sat up suddenly, looked at the medical mirror next to him, and blinked.
"Huh? Why is it black?" She turned her head and looked at Shizune, "I remember it was red Sharingan just now? Why did it become black when it was put in my eye sockets?"
Tsunade put her hands together, letting the chakra in her body surge up, trying to eliminate the possible presence of Genjutsu, but at this moment, she found that her chakra was rushing to her eyes. She stared at Shizune, looking at the hairs and pores on Shizune's face.
"Shizune, your skin needs maintenance." She muttered subconsciously.
"Lady Tsunade, Sharingan!" Shizune exclaimed, she witnessed all these changes from beginning to end.
Before the operation started, the pair of eyes in the test tube were still blood-red Sharingan, but after he completed the transplantation of Lady Tsunade, the pair of Sharingan turned into ordinary black eyes in the blink of an eye.
But just now, the moment Lady Tsunade put his hands together, the pair of black pupils turned red in an instant, leaving three small black Tomoe slowly rotating.
It's really a magical feeling.
Tsunade turned around and looked around everything in the operating room. Even the fine dust in the air was clearly visible. She waved her hand in front of her eyes. Her skin was well maintained, tight, delicate, and shiny.
"Shizune, try it with Ninjutsu!" she urged.
In her eyes, Shizune's Hand Seals was exceptionally slow. Not only that, she seemed to feel how Shizune's chakra flowed.
She also started Hand Seals, the first seal was Wei, she was a little slower than Shizune, the second seal was Si, she and Shizune were used at the same time, the third seal was Yin, she was one step faster than Shizune.
"Clone Technique!"
The two shouted at the same time, but Tsunade's clone took one step ahead of Shizune and appeared next to him.
"Quick, quick, try Genjutsu again..." She blew up her clone and continued to urge Shizune.
Tsunade was like a child who got a new toy, so Shizune had no choice but to bite the bullet and try out various functions of Sharingan with her, from the most basic insights to copying Ninjutsu, and even Genjutsu, both of whom were not very good at it, tried them all.
"I remember that the Sharingan of Kakashi cannot be turned off. The village seems to have checked it. It is obvious that every nerve is connected, but there is no way to turn it on and off freely like you Lady Tsunade."
Shizune sat on his knees in front of Tsunade, taking a small bite while watching Tsunade constantly turn on and off his Sharingan. His teacher seemed to be having a great time.
"Maybe this pair of Sharingan is different, or maybe I am different?" Tsunade frowned, feeling the situation inside his body.
She is now fully able to control the opening and closing of Sharingan by herself, but it seems that after closing, her chakra will still flow to these eyes bit by bit.
She didn't know whether it was because the pair of Sharingan had been soaked in the test tube for too long and had lost too much, or for some other reason.
But when her own chakra slowly flowed to these eyes, chakra also poured out of the eyes and entered her body.
She had checked that there was nothing unusual about those chakras except that they had some spookiness that was unique to Uchiha. After entering her body, they merged with her original chakras and became indistinguishable from each other.
This kind of circulation and integration is very similar to what the Money Exchange boss said.
Two into one.
