Main World.
Summer, Konoha Year 23.
British Continent, New Capital.
Imperial Palace, Gravity Room.
Jilan stood in the center of the training room, his small body utterly still under ten times normal gravity. He was three that year, dressed in a small, dark gray training outfit, his short black hair drooping slightly in the gravity field. His eyes were scarlet, the one-tomoe Sharingan slowly spinning in his sockets. There was no sweat on his face, his breathing was steady, and his muscles were relaxed-ten times normal gravity was already no different from normal gravity to him.
Toyotomi Yinglang stood at the edge of the training room, his hands behind his back, his moon-white Kariginu gleaming softly under the lights. Kushina stood beside him with her arms folded, her eyes full of heartache, but she said nothing. Jilan had begun training in the Gravity Room at age two, progressing from double to tenfold gravity, one hour every day without fail. It pained her, but she knew it was good for him.
"He's already adapted to tenfold gravity." Toyotomi Yinglang's voice was calm.
"Jilan, jump."
Jilan nodded, bent his legs slightly, then leaped. His body shot toward the ceiling like a cannonball, tracing an arc through the air before landing steadily on a beam ten meters high. The beam was only a palm's width across, but he stood on it without moving. Kushina's pupils contracted slightly. "That... is that a height a three-year-old can jump?"
"If he can jump ten meters under tenfold gravity, he can jump a hundred meters under normal gravity." Toyotomi Yinglang's voice was calm.
"A hundred meters is enough to jump onto Konoha's Hokage Building."
Jilan jumped down from the beam and landed silently. His knees bent slightly to absorb the impact, then he straightened.
"One punch," Toyotomi
