Lord of the Flies: Revenge of the Uchiha Synthesis

I was once an insignificant fly that met its end under the swats of humans. When I opened my eyes again, I was transported into the bloody world of Naruto and became an orphan of the Uchiha clan. I was randomly named Uchiha Fly. No one knew that deep in my spiritual world, there was a [Synthesis Matrix of All Things] from another world suspended. It uses spiritual power as fire and all things as materials. It can melt flesh and blood, refine energy, and create strange objects. It gives me the power to distort reality amidst randomness and taboos. On the night of genocide, the blood moon hangs high. I didn't cry, I didn't run away. I stood amidst the mountains of corpses and seas of blood of my tribe, growing cold ecstasy out of despair. The corpses and souls of my enemies became my first precious synthetic materials. Since then, there has been a revenge fly in the shadow of Konoha who feeds on hatred and uses synthesis as a blade. The undead of Uchiha walk with me, and the weird synthetic beasts are my army. I don't save, I don't forgive, I only devour, I only destroy. When the rot-winged wolf composed of corpse and soul let out its first howl, the nightmare of the entire ninja world officially began.
