Back in the village, Uchiha Mu clutched his head. The clone helping him process documents had vanished, and its memories, along with all those documents, made his head ache. The two women were already used to the sight.
After all, they often had the same problem. One handled finances and the barrier, while the other handled sensory duties and administration. Each of them did the work of several people. Without shadow clones, they might not have been able to keep up.
They were short on shinobi to begin with, and those with management skills were even rarer. Until they finished training the next generation, they had no choice but to fill the gaps with shadow clones.
This really is the Multiple Workhorse Technique, Uchiha Mu grumbled inwardly as he recovered.
With the Five Kage Summit over, the Shinobi World had fully entered a brief period of peace. Even the small nations were no exception. The reason was simple: the major nations were racing to master the power of the tailed beasts.
Although humans in this era could not defeat the tailed beasts, people capable of doing so would gradually emerge over time. By then, all they would lack to control them would be sealing jutsu.
Although the original story explained that they feared the Uzumaki Clan's sealing jutsu, they wanted those techniques even more, while also wanting to prevent their own tailed beasts from being sealed. That was why they would join forces with Kirigakure. Otherwise, they would hardly help Kirigakure just because they had nothing better to do. It would be a miracle if they did not stab it in the back.
It was precisely this tailed-beast arms race that brought peace to the Shinobi World. Once people lived in peace and their emotions settled, a baby boom followed.
