A ninja who made a name for himself in the shinobi world didn't necessarily have a gift for teaching.
Take Minato Namikaze and Hatake Kakashi from the original story. Both were formidable shinobi, yet their students didn't exactly turn out well. Right now, Uchiha Yue had the same impression of Tsunade. He acknowledged that she was incredibly strong, but her teaching skills were only average.
When teaching Uchiha Yue, Tsunade simply laid out everything she had figured out herself. How much he understood was up to his own ability to learn. Fortunately, Uchiha Yue had exceptionally strong mental energy and had inherited the excellent habit of taking notes. Otherwise, Tsunade's information-dump style of teaching might really have ruined him.
Tsunade was clearly very pleased with Uchiha Yue's attitude toward learning. At the very least, she praised him when he pulled out his notes and began writing things down. As Tsunade continued her information-dump lesson, Uchiha Yue gradually began to understand what Medical Ninjutsu was about. After all, he already had a wealth of theoretical knowledge, and Tsunade held nothing back while teaching him. As a result, he quickly grasped how to use Medical Ninjutsu.
Medical Ninjutsu was a type of ninjutsu, and practicing it required exceptional chakra control.
To learn Medical Ninjutsu, one needed a certain degree of chakra control.
And the more deeply one studied Medical Ninjutsu, the more one's chakra control had to improve.
For that reason, very few people in the shinobi world could truly master the essence of Medical Ninjutsu.
Uchiha Yue had tremendous mental energy and had been honing his chakra control all along, so he was fully qualified to learn Medical Ninjutsu. In fact, as long as he worked hard and had Tsunade's dedicated instruction, he had every chance of reaching the pinnacle of Medical Ninjutsu. The only catch was that he felt some resistance to learning it.
Still, Uchiha Yue couldn't show a lack of interest in front of Tsunade.
After all, Tsunade held the title of one of the Sannin and had considerable standing in Konoha. Uchiha Yue didn't want to provoke his already quick-tempered teacher.
Besides, he had his own plans.
While training under Tsunade, Uchiha Yue figured he might as well learn what she taught him. After all, mastering Medical Ninjutsu would help him protect himself in the heat of battle. But he would only practice it while training with Tsunade. There was no way he would go home and keep practicing according to her instructions.
He couldn't give up his own training plan. Even if a powerful shinobi like Tsunade came up with one, he would still reject it.
After Tsunade had given Uchiha Yue an initial explanation of the principles behind Medical Ninjutsu, she quizzed him with a few questions to see if his answers would satisfy her. To Tsunade's mild surprise, Uchiha Yue's strong memory and comprehension allowed him to absorb and fully understand what she had just taught him in a short time. He could even apply the concepts to new situations.
Then...
Seeing how well her student had grasped the theory, Tsunade unsealed a scroll.
As the sealing scroll opened, it revealed a fish that had stopped breathing three hours earlier. It was the subject Uchiha Yue would be experimenting on next.
"Yue, use the method I taught you to bring this fish back to life."
Tsunade placed the fish that had been dead for three hours in front of Uchiha Yue, folded her arms across her chest, and gave him a direct order.
Seeing that Tsunade wanted him to try it himself, Uchiha Yue nodded. He gathered chakra between his hands, and a dark green light began to shimmer there. His chakra had been converted into the form used for Medical Ninjutsu.
Seeing Uchiha Yue successfully convert his chakra on the first try, Tsunade gave a satisfied nod.
But Uchiha Yue knitted his brows slightly. Then he looked over at Tsunade and said, "Sensei, I have a question."
"Go ahead," Tsunade said with a nod.
"Mm."
Uchiha Yue paused briefly to gather his thoughts, then said, "Sensei, I followed your method for converting chakra, and I can now successfully change the chakra in my body into the form used for Medical Ninjutsu. But I've noticed that Medical Ninjutsu chakra seems a little similar to the Body Energy in a person's body. Could there be some connection between them?"
"Heh. You really are talented. You've already discovered the secret behind Medical Ninjutsu?"
Hearing Uchiha Yue's question, Tsunade smiled with satisfaction. "That's right. Medical Ninjutsu chakra really is very similar to the Body Energy inside a person. Or rather, Medical Ninjutsu chakra is created by transforming chakra to imitate the body's own Body Energy. Body Energy is a remarkable force with properties like healing and detoxification. But while it remains inside the body, it can only instinctively heal injuries and ease certain toxins. Body Energy transformed through Medical Ninjutsu, on the other hand, can actively heal injuries and remove toxins. That's what we call Medical Ninjutsu chakra."
As she spoke, Tsunade walked over and gave Uchiha Yue a light pat on the shoulder. She continued, "I'm glad you asked that question, Yue. I knew I was right about you. You really are talented at learning Medical Ninjutsu. The fact that you created a technique like the Rasengan proves that your talent for techniques and your chakra control are both far beyond the ordinary. If you focus on studying Medical Ninjutsu, you could become far more accomplished in it than I am."
"And..."
At that, a mysterious smile appeared at the corner of Tsunade's mouth. She gave Uchiha Yue a meaningful look and said, "And, Yue, there's a reason I want you to learn Medical Ninjutsu. I understand your situation. You have reservations about learning it because you're worried it'll get in the way of training in other areas, don't you?"
"Mm, that's right."
Since Tsunade had brought it up, Uchiha Yue no longer had any reason to hold back. He answered directly, "Just like you said, Sensei, I'm worried it'll interfere with my other training. I'm afraid Medical Ninjutsu will take up too much of my time, so I'm a little reluctant to learn it."
"Hehe, that's not a problem."
In response, Tsunade waved a hand. "Once you've truly mastered Medical Ninjutsu, you'll understand why I'm teaching it to you instead of training you in some other way. All right, it's time to train. Focus on completing the training plan I made for you. Let's begin!"
"Yes!"
As soon as Tsunade finished speaking, Uchiha Yue answered solemnly, then turned his attention to the dead fish in front of him.
Then...
After taking a deep breath, Uchiha Yue controlled the chakra in his hands and slowly lowered them over the dead fish.
At the same time, his expression grew even more serious.
His Medical Ninjutsu training was only truly beginning now!
