Naruto: I Have a Gravity Training Room

After listening to the story, Natsuki didn't feel like lingering—better not to interrupt Team 7's training.

So he bid them farewell.

"Natsuki, wait a sec!"

Sasuke suddenly spoke up. "There's something I want to show you—watch this before you go!"

With that, he turned toward a massive boulder, raised his hand, and a spear of lightning chakra formed in his grip. As he thrust forward, the spear shot straight into the boulder.

"Raiton: Chidori Eisō (Lightning Style: Chidori Sharp Spear)!"

With a thunderous boom, the boulder shattered into pieces on the spot!

Naruto and Sakura stared in shock—clearly, they'd had no idea Sasuke had developed such a technique.

Even Tenten jumped a little in surprise. Still, she often chatted about jutsu theory with Natsuki, so she wasn't too shocked—she knew Sasuke had been working on new moves.

Natsuki clapped his hands. "Nice! Looks like you've successfully created a new technique!"

Sasuke gave a small nod. "Just one so far. I still need to develop more powerful techniques. Natsuki, just wait—I'll catch up to you!"

"Alright, I'll be waiting for your challenge!"
