At an abandoned quarry more than ten kilometers outside Konoha's southern gate, the surrounding rocks were covered in lightning-scorched cracks and spiral-shaped craters.
These were the traces left behind by Boruto and Naruto's training over the past four days.
After four days of rest, adult Sasuke, who had been resting nearby, had fully recovered his Chakra. He and Jiraiya sat beneath the shade of a tree—one wiping down his Kusanagi Sword with one hand, the other constantly writing something on paper, occasionally beaming with excitement.
Suddenly, adult Sasuke sensed the space around them beginning to ripple. He gripped the hilt of his Kusanagi Sword in reverse and looked up ahead. The sword immediately erupted with dazzling blue electrical arcs.
