Tsunade-sama rudely cut off Hagoromo's forced attempt at popular science. She refused this kind of forced indoctrination at the level of thought. By instinct, she felt that what Hagoromo had just said might be correct, but it held no meaning for her.
In short, she understood that Hagoromo simply could not use Magnet Release.
Hagoromo shut up resentfully. Everyone had a soul that longed to explain things, after all, and his had just been ruthlessly interrupted. To be honest, he felt a little hurt.
Well, he was injured right now anyway.
Then Tsunade said, "In any case, you performed very well on the battlefield that night. Tactically speaking, you helped me out tremendously, and as a result, some of Konoha's strategic arrangements were maintained as well. What you did far exceeded the duty a Genin should have fulfilled. As the commander of this battlefield, I owe you a favor."
Uh, owing him a favor was a little too vague. Could she give him something more tangible? Hagoromo thought helplessly. Of course, as long as he had even a little sense, there was no way he would say something that blatant aloud.
But unexpectedly, there really was a benefit. Tsunade-sama did not deal in empty words.
"I heard from Kushina that you enjoy learning all kinds of advanced ninjutsu. Is there anything else you want to learn? If I know it, I can teach it to you. If I don't, then as long as it's a Konoha technique, even a high-level forbidden technique, I can get it for you. Consider it repayment for the favor I owe you."
"..."
Hagoromo froze. There was such a good thing? He could learn an advanced ninjutsu? But what should he learn from Tsunade?
"Let me make this clear first: you only get one chance."
