Do You Call This Useless? My Ninjutsu Is All SSS

Good news: Osamu Kinoshita has traveled through time, and it's still a ninja world. Bad news: As soon as he started, he was stamped by the examiner as "incomplete meridians, lifelong chunin" and became a joke in the whole village. Even worse news: His golden finger is a very vicious system, talking about "requirements review", "version iteration" and "this bug needs to be fixed". But—— As long as you have seen the ninjutsu once, it can fully analyze, reproduce and optimize it. Someone else had practiced a famous stunt for ten years, but he copied it in three minutes and made it ten times better than the original version. Fire escape? Copy. Physical skills? Copy. Blood inheritance limit? Also copy it and upgrade it to SSS level by the way. So there is a saying in the ninja world: Never use your special move in front of Kinoshita Osamu, otherwise it will become someone else's signature tomorrow. "Good-for-nothing?" He smiled, "I just turned your special skills into my entry-level skills." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
