If you didn't improve the strength of ninjas and turned instead to studying agriculture or something else, then when the village was breached, it would all end up benefiting someone else.
However, with the arrival of peace, ninjas had gradually begun to lose their advantage, yet education in other fields had failed to fill the gap.
That was what had led to these problems.
Torikaze had noticed this a long time ago, but he had never known how to address it. On top of that, he had so many matters to deal with that he had to prioritize them by urgency.
Now that he had some free time, he planned to spend a large amount of Tranquility Points to give it a try and see whether he could get some useful teaching materials.
"Then let's begin! Setting everything else aside, even a set of middle-school-level mathematics and physics textbooks would do."
As for elementary-school-level material, Konoha's ninjas already had that.
As for the more powerful Kage and clan heads, they had learned even more, roughly equivalent to a high school education.
That was already enough knowledge to lead a clan.
As for anything more advanced, it probably did not exist. In the entire Shinobi World, only Torikaze had ever attended university.
He idly browsed the system Shop, but the thing was truly rather demanding.
The Shop's main products were things that improved one's strength, while the rest were miscellaneous items, such as Blueprints or various strange and unusual objects.
But books were genuinely rare, let alone educational books. He had practically never seen any.
Torikaze was only trying his luck. If there were none, then so be it.
It was not as if he had never considered writing the textbooks himself, but he had lived in the world of Naruto
