Masaru was a normal Jonin from Kumogakure, leader of a border patrol squad. Still in the prime of his life, he could consider his life a success. Even the area he patrolled was relatively safe, so he was a little lax and went a little away from his squad to complete his morning routine, which soon became the worst mistake of his life.
Just when he was about to pull his pants up after doing the deed, someone attacked him from behind, targeting his neck, most likely to make him unconscious, because there were better ways to kill him than using simple hands.
Using his experience, he was able to dodge the attack at the cost of his dignity and pants which were now unusable.
"Who are you?" Masaru asked. Even though his tone was threatening, his half-naked form didn't help maintain the threat at all, but Masaru was not affected by it. What would he do with dignity if he didn't have his life?
But no reply came from the enemy who was wearing a complete black dress, almost looking like a shadow. Before he could say anything more, he fell under a genjutsu. How did he know he fell under a genjutsu?
Well, if fish climbing trees was a good enough reason for him to believe so. But before he could disperse his chakra, an impact on the back of his neck made him unconscious for good.
The next thing he knew, he was in some kind of hospital with his hands and legs tied and mouth closed. He looked around, only to find a ninja who was pretty famous in Kumo after his latest performance in the chunin exam. This in itself would have been trouble if he was not wearing doctor's clothes, with a blade in his hand.
Masaru turned to see a chance to run, only to find the Hokage of Konoha himself sitting in the room, looking toward him like he was some exotic animal, accompanied by a beautiful-looking lady who had the same look in her eyes.
Seeing this, he felt his whole life flash through his eyes, with numerous possibilities coming to his mind, each more absurd than the other. In one, Konoha was doing some business of ninja organ trafficking; in another, he was being transformed into a human bomb who would do extensive damage to his village.
If any of the three people could hear his thoughts, they might even consider some of them with how good they were. But before he could reach any conclusion, the doctor coughed. He looked toward him only to find two red glowing eyes with beautiful patterns in them, but just like those before him, he couldn't enjoy the look for too long either, transported to a fiery hell himself.
It had to be considered that even a normal 3-tomoe wielding Uchiha was to be considered a foe not to fight alone even for a Jonin because they would fall for Uchiha's genjutsu. So if a Jonin who could even fall in genjutsu with 3-tomoe sharingan falls under genjutsu with the help of full power of sharingan, then there is utterly no chance for him to come out of it on his own.
In front of the shocked eyes of Hiruzen and Mitsuru, Kaida easily operated on the Jonin. With the effect of numerous anesthetics, there was no pain in the process at all, with Kaida moving precisely and skillfully, easily operating the area around heart and solar plexus in a matter of minutes.
Hiruzen and Mitsuru left their eyes open because the ninja in front of them was doing the work of 3 specialist medical ninja alone, without the help of a single Shadow clone, all by himself. Normally such surgery would be led by a specialist with the help of a team of other medical ninja for support.
But Kaida was doing all that alone, and that was not the surprising part yet, as the effect of surgery disappeared at a shocking pace. Kaida was now ready for the second part of the surgery, once again his eyes shining red, as he marked the chakra network of the ninja on their body, with the possible infected parts being drawn by red pen.
Even though he didn't need such thing in real cases as he could see the chakra flow himself, for a ninja who is perfectly fine he had to point out which parts he had to operate.
After completing the preparation, he made a series of hand signs and once again the same glow which appeared in previous 20 operations appeared on his hand but this time even more thin and sharp.
"Is that?..."
"Yes, it is chakra scalpel, but somehow he is maintaining it at extreme thinness. Even I can't do that for now, and doubt even Tsunade would be able to," Hiruzen answered, but he was also equally shocked at the scene.
And the jutsu which would need immense concentration just to maintain was used in front of them like it was the normal scalpel used in hospitals.
With precision that would put machines to shame, Kaida slowly dissected the chakra veins and then used his own chakra to maintain the passage all by himself.
If his earlier work was hard, now it was insane which he was doing without any problem at all, well not anything they could tell, but he was using his sharingan to maintain the extreme fineness and control required, even forgetting about the two people in the room. All of his concentration was on the operation;
the amount of chakra he used on the single operation was enough to put five Jonins in chakra-depleted state easily, but for his chakra reserve it was not even 5 percent though the strain was real.
As soon as the operation was completed, he sat down panting while making a shadow clone to make the final notes for his experimentation, and to his delight everything was perfect in the last operation. Even though there was a little stretch in the chakra network of the Jonin, it was nothing a few weeks of medicine and rest couldn't fix.
Mitsuru and Hiruzen came out of their shock after Kaida created his shadow clone, and went to check the results themselves too, delighted to see that there was no problem with the procedure at all.
Their faces gained a deep smile, not because of a particularly successful and new procedure to treat an ultra-rare disease, but at the emergence of a new S-rank medical ninja of Konoha.
It was different from gaining another S-rank physical fighter, because with good medical ninja an injured ninja could be healed and fight again multiple times, as shown by Tsunade. With her and another S-rank medical ninja, Konoha would become an immortal enemy to its enemies.
Just thinking about it was increasing the smile on Hiruzen's face, while Mitsuru was just genuinely happy about her student's progress, who may have even left her behind in some parts.
"Good job Kaida. With this, we can treat Itachi in no time," Mitsuru said, her hand glowing green as she scanned the body of the jonin laying in front of her, her eyes twinkling.
"About that sensei, I will need your help with...
