Chapter 834: Testing each other
With a puzzled expression, Fujin asked, "What do you mean?"
Tsunade explained, "Learning these things takes a lot of time… Spirit Transformation jutsu is just a single jutsu, so it's still understandable. However, Medical Ninjutsu is a very deep field. You need to devote a lot of time to become an acceptable Medical Ninja. It's the same with Fuinjutsu. Why did you take away the time you could have used to improve your Wind Release or other combat-oriented Ninjutsus further?"
Fujin thought, 'Ah, that's what she was referring to. It's understandable. I don't think anyone else learned Fuinjutsu and Medical Ninjutsu like I did.'
Fujin remembered the days when he used to feel like he needed 72 hours in a day. He had used Shadow Clones extensively for years to learn Fuinjutsu. As for Medical Ninjutsu, he made nearly every senior Medical ninja working in the Konoha Hospital devote several weeks to guide him. It had been so extreme that even Hiruzen had become worried. Tsunade, who had just returned to Konoha, was obviously unaware of such information.
Fujin smiled and took a seat as well. He said, "I never thought from this perspective. I always found Fuinjutsu interesting. I used to read and practice it whenever I was out of chakra after my training sessions. It didn't eat into my training time apart from some instances.
As for Medical Ninjutsu, my team once fell into a trap and we were almost wiped out. Only I managed to escape while carrying my injured team leader. It took me several hours to bring him to the Land of Fire and find a patrol camp where he could be healed properly.
That motivated me to learn a few basic healing jutsus like the Mystical Palm jutsu. Other than providing immediate treatment to any injured teammate, the jutsu also has a huge potential to change the tides of a battle. I'm sure no one knows more than you how much of an upper hand you will have in a battle if you can heal yourself while your enemy can't."
Tsunade nodded. It could turn a close battle into an easy victory if the ninja had sufficient chakra left. Fujin continued, "That said, you're correct. I didn't focus on other aspects of medical ninjutsu back then even though Yoshi-sensei pestered me continuously due to the limited time. I only accepted his offer after I reached a bottleneck in my Wind Release."
Tsunade's eyes twitched. She thought, 'So, instead of resting after exhausting his chakra from Ninjutsu training, he learnt Fuinjutsu while waiting for his body to regenerate chakra to train again? And, he hit a bottleneck in Wind Release in his early teens? Did he do nothing except train?'
