Naruto: Starting by Devouring the Eternal Mangekyo Sharingan

[Open with Eternal Eye + Devouring System + Decisive Killer + Behind-the-Scenes Mastermind] After transmigrating into the Fourth Great Ninja War, Uchiha Xuan awakens in the Uchiha Sacred Land, bearing the Myriad Devouring System! "A battlefield? No, this is his hunting ground!" Devouring White Zetsu grants Wood Style; devouring powerful Edo Tensei warriors plunders Kekkei Genkai; devouring Tailed Beasts controls the might of the Six Paths! Uchiha Madara: "My Eye of the Moon Plan... why does it have a loophole?" Kaguya: "His devouring power surpasses even mine!" Naruto & Sasuke: "He is the greatest crisis of the ninja world!" While the Allied Shinobi Forces still fight for peace, Uchiha Xuan looks down upon all living beings. His goal—to devour Kaguya, seize the power of gods, and establish a Uchiha Empire where he reigns supreme! Crushing everything with absolute power, ending the chaotic era with an iron fist. This is the peace he defines!
