The next day.

Shinji, who received the news from Iruka, rushed to Konoha Hospital after eating at noon after completing the morning class of the ninja school.

"Shinji Uchiha reports to you."

After finding the medical ninja in charge of guiding him, Shinji stepped forward and bowed.

The other party is a female ninja in her twenties, with long hair tied up, and she looks very capable.

She looked at Shinji and frowned slightly: "You are Uchiha Shinji, how old are you?" ”

"Eight years old!"

"Eight!?" She shook her head, her expression a little crying and laughing: "The village is too chaotic, how did you send an eight-year-old child to me." ”

Shinji smiled: "Because I'm a genius!" ”

"Genius?" She was a little surprised, but immediately restrained the emotions on her face, and said flatly: "My name is Kaoru Kusina, and I am your instructor." ”

Shinji saluted with a smile: "Kusina-sensei." ”

Kaoru Kusina casually picked up a book and threw it to Shinji: "Read this book first, and then come to me." ”

Shinji took the book and looked at it, the cover of the book read "Atlas of Human Structure", he thought about it, accepted the book and left silently.

I didn't expect Shinji to leave so simply, Kaoru Kusina was ready to teach Shinji a lesson, and he choked back, so he had to pout his lips and whispered, "I want to see how talented you are!" ”

Shinji, who left Konoha Hospital, did not go back to the apartment, but turned around and went to the archives.

He could naturally see that Kaoru Kusina had the intention of making things difficult for him, but for him who wanted to master medical ninjutsu, it was natural for him to learn a foundation like "Atlas of Human Body Structure".

So he not only studied "Atlas of Human Structure" seriously, but also borrowed all the books on medical ninjutsu that he could find in the archives.

A week later.

Shinji came to Konoha Hospital again with "Atlas of Human Structure" and found Kaoru Kusina: "Mr. Kusina, I've finished reading this book." ”

When Kaoru Kusina saw Shinji, he was stunned for a moment.

Shinji didn't show up for a week, and she thought that Shinji had given up on learning medical ninjutsu.

After taking over the "Atlas of Human Body Structure", she randomly picked a few questions and took the test for Shinji, and when she saw Shinji's answers, she was shocked, and said secretly: "He finished this book in just one week?" It took me a whole month to read it! ”

Somewhat unconvinced, she took out a book from the drawer and threw it to Shinji: "Read this one again." ”

Shinji looked at the cover of the book "Hematology", smiled and said, "Mr. Kusina, I have also finished reading this one." ”

Kaoru Kusina's face stiffened, and he took out another copy of "Chakra and Muscle Tissue".

Shinji didn't wait for the other party to hand it over, and smiled, "I've seen it too." ”

Kaoru Kusina was a little unconvinced, so she picked out the content of these books and took the test for Shinji, and the result was the same as before, and all the answers were fluent.

Her face was full of doubts: "When did you read these books?" ”

"It's just the past few days." Shinji pointed to the back two books and said, "Except for the 'Atlas of Human Structure' you gave me, I borrowed the rest from the archives and benefited a lot. ”

Kaoru Kusa put away the surprise on her face and said with a straight face: "You can't master medical ninjutsu just by rote memorization, you come with me." ”

With that, Kaoru Kusina led Shinji to the laboratory.

A live fish was taken out from the pool on the side, and Kaoru Kusina-kun slashed the abdomen of the live fish with a scalpel, and in an instant, the live fish that was still alive just now was disemboweled, and it wilted.

At this time, Kaoru Kusa made a seal, and used the 'palm fairy technique' to gently press on the belly of the fish, and the cut belly of the fish immediately healed, and the fish also regained its vitality and jumped up.

"See? This is the most basic medical ninjutsu 'palm immortal technique', beginners need to pass the seal to perform it, and once they are proficient, they don't need to seal it. You should remember the order of the seals just now, go back and practice well, and if you haven't mastered it in a month, you can find it again..."

Kaoru Kusina spoke, her voice gradually weakening.

Because she saw Shinji meticulously start the seal, and then a stream of green chakra shrouded Shinji's palm.

Shinji looked at Kaoru Kusina, "Mr. Kusina, is that so?" ”

Kaoru Kusa muttered, "It's not bad, it's not bad..."

Shinji looked at the live fish on the test bench, turned to Kaoru Kusina, and asked, "Can I try it?" ”

Kaoru Kusina nodded and stepped aside.

Shinji imitated Kaoru Kusina and slashed shallowly at the fish's belly with a scalpel, and then launched the 'Palm Immortal Technique' to come over.

In an instant, the interaction between Chakra and the body surface of the living fish was fed back into Shinji's brain.

"This feeling..."

He gradually felt that the principle of medical ninjutsu was not to treat, but to instill the yang attribute chakra into the body of the injured person, so that the injured person could heal themselves.

"That's not right!"

He soon overturned the idea.

If only the yang attribute chakra is instilled into the injured person's body, then the medical ninja will not need to learn the complex structure of the human body.

So he quickly realized that instilling the yang attribute chakra into the injured person's body was the most elementary means of healing.

So he stopped, took the scalpel and gestured at the live fish, and asked Kaoru Kusina, "Mr. Kusina, is it okay?" ”

Kaoru Kusina didn't quite understand what Shinji wanted to do, but seeing that Shinji had mastered the 'palm immortal technique' so quickly, he nodded subconsciously.

Syllable...

Shinji cut off the head of the fish directly like cooking.

“！？”

Kaoru Kusina was dumbfounded.

Shinji took advantage of the fact that the fish was still pumping, and hurriedly combined the head and body of the fish, and then launched the 'palm immortal technique' against the broken opening.

This time, he did not stop at instilling the yang attribute chakra into the fish's body, but directly manipulated the chakra, participated in and even led the recovery of the wound.

"Do you prioritize restoring the trachea or blood vessels? Is this a fish gill? Fishbones heal so slower than muscle tissue..."

He pondered and tried.

Soon, the disconnected head and body of the fish were connected by him.

Of course, the fish is already dead.

Looking at the fish that had completely lost signs of life, Shinji felt a little regretful: "If it was faster, maybe I could save it." ”

After that, Shinji glanced at the pool not far away, and saw that there were several big fish in it, so he hurriedly asked Kaoru Kusina, "Mr. Kusina, can I try again?" ”

"Uh, good... Good! ”

......

Ninja School.

Mizuki led a white-haired boy to Naruto, Sasuke's class, and announced to the students in the audience, "Everyone, be quiet, I'll introduce you to a new classmate, his name is Junmaro, and he will be a member of your class from today on." ”

"It's white hair!"

"Wow, he's so tall!"

"How do you look cooler than Sasuke!"

There was immediately a lot of discussion in the audience.

Sasuke glanced at Kimimaro, then withdrew his gaze.

Now among his peers, only Shinji and Ningji can enter his vision, and the others, he doesn't care about them at all.

At this moment, Jun Maro came to Sasuke with an indifferent expression: "Are you Uchiha Sasuke?" I'm going to challenge you! ”
