The Night of the Uchiha Massacre: Incarnating as a Calamity God

I was just rewatching Tiga fight the final boss, the evil god Gatanothor, when I transmigrated into the Naruto world. The good news: I became a member of the Uchiha Clan and have a chance to defy fate. The bad news: Tonight is the night of the clan's massacre. Fortunately, I awakened the Mangekyo Sharingan and the power of an evil god just before I died. Now it's time for my revenge. I will represent the spirits of the fallen Uchiha and destroy the entire ninja world.
