Naruto: I'm Uchiha Byakuya — Every Negative Emotion Makes Me Stronger

【Naruto Fanfic + Negative Energy System + Uchiha Byakuya + Anti-Cliché Harvest + Not Soft-Hearted / No Whitewashing + Beat Down All Konoha Higher-Ups + Ruthless / Not Soft-Hearted + HE】 【Naruto Crossover】+【Negative Energy System】+【Uchiha Byakuya】+【Anti-Cliché Harvest】+【Not Soft-Hearted / No Whitewashing】+【Beat Down All Konoha Higher-Ups】 Transmigrated into the Naruto world as an orphan of the Uchiha clan, bound to the 【Negative Energy System】. As long as a target falls into anger, shame, fear, anxiety, jealousy… he gains negative energy, which can be exchanged for ninjutsu, attribute points, and even unlock the Mangekyō Sharingan! Thus, Uchiha Byakuya began his "collection" route. Facing Sarutobi Shin'nosuke, the Hokage's son: "You wouldn't want your old man to know about your strong-arm dealings, would you?" —Two slaps across the face. Negative energy +1000. Wind Release ninjutsu obtained. Facing Uchiha Fugaku: "You worthless trash, what qualification do you have to be clan head?" —Public beatdown, stomping and crushing his face. Negative energy +999. Genjutsu attributes skyrocketed. Facing Third Hokage Sarutobi Hiruzen: "Lord Hokage, the interrogation report of your son's defection from the village—why don't you bend down and pick it up?" —Extorted 100 million ryo. Third Hokage's rage maxed out. Shuriken Shadow Clone Technique obtained. Facing Danzo: "I don't just dare to curse you out, I dare to hit you." —Public slaps, arm chopped off, Root organization wiped out entirely. Negative energy +10000. Facing Mikoto: "You wouldn't want your father to die in prison, would you?" —Effortlessly handled the Uchiha young lady, and by the way harvested the clan head like a leek. Things the Hokage didn't dare manage, the Police Force managed. People the Hokage didn't dare kill, the Police Force killed. One line: If the Hokage can manage it, we manage it. If the Hokage can't, we manage it even more. Sarutobi Hiruzen: The "Ninja Hero" turned into a "Ninja Coward"—100 million ryo for peace of mind. Shimura Danzo: Konoha Elder? Still getting slapped. Eyes dug out without hesitation. Uchiha Fugaku: Trash clan head candidate, sentenced to rot in prison for life. Uchiha In: Sidelined by his own daughter and clansmen working together, so angry he coughed up blood. Byakuya: I just wanted to collect some negative energy. How did the entire Konoha get broken? ⚠️ System + negative energy harvesting—the angrier they get, the stronger you become! ⚠️ Mangekyō Sharingan unlocked with ease. Dual cultivation of dōjutsu "Futsu-no-Mitama" + "Kamui"! ⚠️ Police Force power maximized. All Konoha shops pay protection fees! ⚠️ Konoha higher-ups all sheared like sheep. Sarutobi Hiruzen's mentality collapsed! ⚠️ Uchiha Mikoto easily won over. The entire Uchiha clan completely controlled! 【Naruto Fanfic / Negative Energy System / Uchiha / Anti-Cliché / Beat Down Higher-Ups / Police Force Rise / Mangekyō Sharingan / Not Soft-Hearted】
