Naruto: Dark-Dark Fruit from the Start, Crushing Every Foe

“Unite the Shinobi World” “Chat Group” “Myriad Worlds” “Ruthless and Decisive” “Kushina” “Invincible” Yu Cheng transmigrated as the young clan leader of the Uzumaki Clan. With the clan’s future destruction looming, he couldn’t afford to waste a single moment! Fortunately, his three adopted sons had each transmigrated to the worlds of One Piece, Demon Slayer, and Soul Land. And so... “Old Cheng! How’s the Dark-Dark Fruit? Hehe... I want Impure World Reincarnation~” “Hey, Old Cheng! I’m now the Imperial Auspicious Beast. Which soul beast do you want as a summoning beast? I’ll send it over!” “Madara Uchiha wants to fight you? The Otsutsuki want to join in too?! Then let’s fight!!? Behold, my Sun Breathing!!!” Years later. Yu Cheng had become a demon king, wielding the supreme supreme-grade sword, standing atop the Black Dragon Ditian. His Rinnegan lowered as he looked down upon the Allied Shinobi Forces, struggling in their death throes. “From this day on, the Shinobi World will be united. And I... will stand above the heavens and become an immortal god!”
