Chapter 162:
After integrating a substantial amount of Uchiha genetic material, Orochimaru found himself with little to do in the village.
With no missions assigned and no urgent research projects, he spent his time with Tsunade or helping to train her younger brother, Nawaki. However, Tsunade was often preoccupied with her own responsibilities, and she would sometimes leave a clone to handle Nawaki's training.
With extra time on his hands, Orochimaru found something new to occupy himself, researching a "scientific ninjutsu scroll."
When he mentioned this project to the Third Hokage, the Hokage had arranged for him a special lab without hesitation and even assigned him a few assistants. After all, if successful, this new tool could significantly boost the combat capabilities of Konoha's shinobi.
So, Orochimaru had dedicated himself to developing it, working on it both in the lab and occasionally at home.
One day, as he was tinkering with a prototype scroll, Nawaki, who had tagged along with Tsunade, caught sight of it.
"Scientific ninjutsu scroll? What's that?" Nawaki asked, crouching down beside him with a look of curiosity.
"It's a scroll that can release ninjutsu without requiring chakra or hand seals," Orochimaru explained.
"A scroll that can release ninjutsu without chakra or hand seals?" Nawaki echoed, his face filled with disbelief. Even Tsunade, who was nearby, raised an eyebrow, skeptical.
