If Blackbeard had taken Luffy's Nika Devil Fruit, Ace had been rescued, and Whitebeard hadn't died at Marineford, what would the future of the world have been like?

On the eve of the summit, an unlucky soul who had traveled from another world was devoured and merged with Douglas Barrett.

The lives of the devil's heirs took a different turn from that point on.

"The Paramecia-type Fusion Fruit allows the user to arrange and combine any object, causing them to fuse. It can also fuse any inorganic matter it touches with its own body to create desired transformations!"

Cells can arrange and combine to become ultimate life forms, ever-changing!

The arrangement and combination of matter—this world is a sandbox game in your hands, and you are the creator!

Microscopic particles arrange and combine, hand-crafted nuclear fusion, devastating the world!

Impel Down is in chaos, a mad dragon emerges from the abyss, turning the entire Deepsea Impel Down into a ship to fight on the summit!

In the Marineford War, a Gundam was launched, and Marineford was sunk with a single shot!

In the new world, we will conquer all and let the name of the Demon God resound throughout the seas!

Hirakawa Seisui, a transmigrator reborn into Konoha. In the ninja world, where bloodlines reign supreme, he was merely a commoner ninja, destined to be cannon fodder on the battlefield. However, fate intervened; he activated the Medical Ninja System. Good news: the system boosted his medical ninjutsu talent to the highest level, making him a Primordial Healing Body. Bad news: it only enhanced his medical ninjutsu talent; on the battlefield, he was still just cannon fodder. "What a piece of trash system! If other transmigrators told me, they'd look down on me, thinking I can't afford a good system." [Completed healing Uchiha Mikoto, reward: one golden magic orb.] [Congratulations on obtaining a magic orb.]

When Jiang Shi woke up, he found himself to be an unlucky guy in the high-risk Fusion Knight world.

Meteorites are the tickets, the system is the profiteer, and the ultimate boss is released during the beginner period?

To survive, he clung tightly to the leg of the Decade Knight!

A monstrous insect king lurking in the school, a conspiracy that distorts time and space, a world on the verge of destruction...

Jiang Shi wields the power of "Blank" and bears the mission of saving the history of knights.

His weapons are? An overload of imagination, a tough (thick) skin, and... whatever you do, don't let the system know about those embarrassing transformation poses he's secretly practicing!

Ye Xuan transmigrated to a fantasy world and became a Quasi-Immortal Emperor in just a million years, hailed as the Number One Emperor of All Heavens. Just when Ye Xuan thought he would continue to break through, becoming an Immortal Emperor, and even transcending the heavens, a multiverse video website appeared, pulling him in. The opening scene was a review of figures from all heavens, showcasing the glorious achievements and highlight performances of the listed powerhouses. One after another, these peerless powerhouses shook countless strong individuals across all heavens and myriad realms, and the number one spot belonged to him—the ultimate battle at the end of the Boundary Sea. He fought three emperors alone, and the fall of an emperor brought sorrow to all heavens. Witnessing that ultimate battle at the end of the Boundary Sea, countless strong individuals across all heavens and myriad realms were utterly shocked…

Fang Nan, who unexpectedly arrived at the duel, began his adventure.

You mean I'm given the Demon Beast card and the Dark Ring right from the start, and you expect me to survive in this world? (Thinking to myself: Should I even eat beef?)

Liu Shi: My lord (╥╯﹏╰╥)ง Someone bullied me

You will face Greeza, Lugiel, Lugiel, Gilbaris, Hyper Zetton, Emperor Alien, Grimd...

Before Roku arrived, he kept talking about destroying the world.

Excellent law-abiding citizen after Rokuro's arrival

Amidst the ruins, the Wind Demon Beast Magbara stood arrogantly to one side, with one foot planted on the Origin Spirit, saying: "So you're called Takamiya Mio?"

Shido, wanting to unleash his protagonist aura, and with a quick kick from Yashiro, interrupted the spellcasting: "So it's a Taoist priest, oh no, Shido, I thought it was a speed bump!"

Fang Nangan's birth is not limited to:

Shinji, after being resurrected, made Shido call him "Dad," and he never paid for meals, always getting free food...

Liu Shi: My lord, do you think stars have a predetermined trajectory?

Fang Nan: Which one does Liu'er like? I'll make it stop.

A country boy, full of dreams, stepped into the labyrinthine city of Orario, only to be quickly slapped in the face by reality. The city didn't welcome him with adventure and battle; Koya, without a familiar to take him in, was forced to work as a laborer for the Loki Familia. "So this is the hero I'm going to raise?" [Yes, Himeko-san.] "What are you for?" [I can do anything you want, and even things you dare not imagine. So spend money, Doctor!] "Mora? You only need Mora?" [Mora is all you need; this is our contract, Ningguang-san.]

Time reversal, time stop, timelines severed… However, in the perilous world of Bleach, for his own safety, he decisively chose to join the Fourth Division. You say I'm lusting after Hana-nee's body?
