Five years had passed since Uchiha Kyu returned to the future, bringing the actual date to around Konoha Year 10. Uchiha Kyu and Uchiha Naoki had grown considerably. They now attended the Ninja Academy while also learning Ninjutsu and combat techniques from Madara.
Over those five years, Uchiha Mu had worked like a beast of burden. Under his efforts, the Hundred-Clan Shinobi Nation had advanced on every front, firmly establishing itself among the Shinobi World's leading powers. News of its progress could no longer be concealed, and the other nations were naturally envious. But Uchiha Mu was still in his prime, and Hashirama was still alive.
More importantly, five years earlier, they had watched a tract of land near the northern coast of the Hundred-Clan Shinobi Nation get erased outright. After that, they did not dare entertain any designs on the nation.
Rōran had joined the Hundred-Clan Shinobi Nation, and Uchiha Mu had renamed it Rōran Province. Queen Sera still governed it, and the two territories were connected through the Heavenly Transfer Technique so supplies could be delivered as quickly as possible.
The Heavenly Transfer Technique was a practical jutsu Uchiha Mu had developed from the Flying Thunder God. By now, the Hundred-Clan Shinobi Village could hardly be called a village anymore. Its outskirts had expanded several times over, though it was still not particularly crowded. After all, the Shinobi World was peaceful and stable now, and people were reluctant to leave comfortable surroundings.
Beyond that, numerous high-rises had sprung up across the Hundred-Clan Shinobi Nation, which had also become a place for merchants from throughout the Shinobi World to start businesses. Most were resellers. The nation's laboratories had maintained Uchiha Mu's approach, churning out new inventions and then putting them on the market.
