"Unify the Ninja World," "Chat Group," "Multiverse," "Decisive and Ruthless," "Kushina," "Invincible"

Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

——————

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

"From this day forward, the ninja world will be unified. And I... will stand high in the heavens, becoming an immortal god!"

"Du Ruo, with an air of righteous indignation, said, 'You saved my life. As repayment, I'll help you be with the one you love.' A short while later, Kikyo stared at Du Ruo, who was holding her, her delicate brows furrowing slightly. 'I think I've been tricked.' Du Ruo blinked. 'Did I break my promise?' Kikyo pursed her lips and whispered softly, '...No.'"

"Having a ship girl transported to the world is already a luxury, but to have a repair system on top of that is cheating!" "Akashi, Vestal, from now on, I'll handle all the port repairs!" Lu Hong said confidently. "Meow?! Then I'll go help Shiranui, meow!" Akashi floated towards the convenience store. "No way, I still need to take care of Enterprise!" Vestal said discontentedly.

"I've transmigrated! I found a tablet, and it's the system for Mythical Beast Palu!" "Huh? How come you have a Deviljho? This isn't the world of Mythical Beast Palu, it's the world of Monster Hunter!?" "What do you mean all the monsters I catch turn into monster girls?" "...Rape!"

Passerby Reincarnator A: "Have you heard? High-level teams have been dying one after another lately. They say they didn't even see the opposing team in team battles before being wiped out by saturation attacks." Passerby Reincarnator B: "More than that! I heard some teams that managed to escape were instantly killed with a single strike before they could even catch their breath. Apparently, that strike was incredibly fast; even teams with time-stop abilities couldn't escape it." Lu Mingqiu, who was out buying necessities, said mysteriously, "Your information is too outdated. I just received news that even a super-level team was wiped out."

Magic is a world of imagination. The great demon Elias, possessing boundless imagination, sought "that magic" for a thousand years without success, and thus chose to come before the great mage, Celia. "Old dwarf, long time no see." The golden-haired elf recalled their journey a thousand years ago. She remembered fighting alongside Elias. She heard the last words of the sage, Avis. She remembered her great determination to deceive the demons. And a thousand years later, the hand that kept stroking her head. "Elias, even now, are you still searching for that magic?" "Yes." "—Unqualified."... Before meeting Elias, Vlame wouldn't have believed that a demon of equal strength to her master existed. She certainly wouldn't have believed that the Demon King currently ruling Ende had...

El is a drifter. He doesn't aspire to be the Pirate King, nor does he seek the One Piece; all he cares about is increasing his stats. A low-key system, a devout individual. —————— Pirates aren't child's play; pirates can be on the same ship as long as their interests align! The head butler, Visa, brandishing a sword, asked the crew, "Do you want to rescue the captain in Impel Down? Raise your hand if you disagree, and then wait for Captain El to come out and kill you." Before going in, I had no dignity? After coming out, who dares disrespect me! El Mordis, the captain of the Angel Pirates, the Blood Calamity, the mastermind behind the underworld. He once said, "The blood I shed, even the sea level has to rise a centimeter to give me face."

As the colossal ship named Black Whale crossed the endless seas, what awaited them was the gatekeeper and the dark continent behind him... What? You're telling me the gatekeeper is Gol D. Roger? The dark continent is full of purple fruits that can awaken Nen abilities if eaten? What...? The Hell Rattlesnake is Kaido? The gas-mist-like life form A is Crocodile? The nurturing beast Papp is Big Mom? Iron Body is actually "Firm"? Finger Pistol is actually "Shoot"? Paper Drawing is actually "Flow"? Observation Haki is actually "Circle"?! Master, I understand! After the Black Whale survived the Great Battle, some died, some escaped, and Kuroro, who rewrote the ending and ultimately won, led the new Phantom Troupe, riding the Black Whale, and set sail! The New World? Isn't this the New World? What kind of extremely evil people are these? Aren't the spiders evil enough?! ...Know...

I'm just a person who wants to live a peaceful life. Although I've taught the girls a few new tricks and knowledge, I absolutely haven't instigated them to overthrow the world. Those are all their own ideas. I'm really not the mastermind! ...First up is *A Certain Scientific Railgun*, others to be determined.

Gathering is a blazing fire, scattering is a calamity for all. Mu Yu, traversing countless worlds, initially intended to quietly develop his power and silently ascend to godhood, but he was frequently targeted by villains. To this, Mu Yu shrugged: "Simple, I'll just become a Venerable..." Naruto: Kaguya Otsutsuki, drooling over Mu Yu's immense chakra, was instantly devoured by Mu Yu! Bleach: Aizen's Dao Heart shattered, and the Hogyoku transformed into a stream of light, flying towards Mu Yu, only to be slapped away – "I won't refine this one." Marvel: The Death Titan Thanos stood opposite Mu Yu in the starry sky, his terrifying aura shattering planets. In the DC universe, Harry Potter, American comic book universes, Pokémon, DNF, Ultraman, Men in Black... villains across countless worlds will face calamity.
