Having transmigrated to One Piece with god-level crafting skills, my first thought was to use Devil Fruits or Devil Fruit users as materials to forge magical artifacts!

My second thought is that this world probably needs to be completely rebuilt to save it!

My third thought was, I have to survive!

[Infinite Flow] + [Growth] + [System] + [Level Up]

Lu Ling transmigrated into her body in a parallel world, which unfortunately turned out to be a dangerous world like Jujutsu Kaisen.

Fortunately, with the system's support, I can become stronger as long as I fight.

---------

The first world: Jujutsu Kaisen Chapter 0.

The second world: Demon Slayer.

The third world: Hunter x Hunter.

The Fourth World: Jujutsu Kaisen Main Story.

......

Watch as Lu Ling travels through different worlds, challenges various bosses, prevents tragedies, and becomes the strongest.

----------

Urajimaru: "Megumi, don't you think Senior Lu went too far?"

Muzan: "Demons see him as if they've seen a demon."

Xiao Jie: "This is the first time I've ever seen someone chase after Hisoka and beat him up."

I've transmigrated and become a genius but a useless person?

What should we do when faced with the brutal swords of the natives?

What?! An incredible stroke of luck has knocked me unconscious! I can now travel to countless worlds?!

Brother, come here.

Ocean, desert, or void – choose one!

If you don't know what that means, then let me explain it to you!

In the endless ocean, ferocious beasts howl, waiting to be fed.

The endless yellow sand in the boundless desert will engulf you.

In the vast emptiness, eternal solitude accompanies you.

Transmigrating into the world of Douluo Continent, without a system and with only level five innate soul power, Qing Mu remained unfazed. His martial soul was Bulbasaur, one of the first generation starter Pokémon, and the kind with unlimited moves. Sunny Day + Photosynthesis + Solar Beam were just basic moves; Grassy Terrain + Grassy Slide + Chlorophyll were equally powerful. No divine Pokémon in Douluo Continent, unable to Mega Evolve? No problem! Mega Evolution, Dynamax, Z-Moves, and Tiium Crystal Form could all be granted with soul rings. And when Qing Mu achieved his title, a resounding name appeared in everyone's ears: people called him… Bulbasaur Douluo!

Ryan, who survives by petty theft after transmigrating to the world of One Piece, looks at the Devil Fruit he just stole and says:

He who steals a hook is executed; he who steals a country becomes a prince… he who steals heaven and earth becomes a saint!

From now on, please call me the Demon Lord of the Heavenly Thief!

When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

In the year X760, a child came to this world with magical powers.

The ever-changing elemental magic...

Protoss magic that summons Protoss to fight...

A transformation spell that can greatly enhance one's strength...

Primarily a support role, it can provide buffs and additional magic to others...

And lost magic such as dragon-slaying magic and space-time magic...

(Don't be so blunt. First, look up why the Uchiha clan was driven to the edge of the village before claiming the Nine-Tails' attack resulted in zero Uchiha casualties.) Liu Yu transmigrated into the Uchiha clan of the Naruto world. Upon entering the world, he faced a difficult choice: choose a useless Uchiha boy or a beautiful Uchiha girl? Liu Yu pondered, "How can I, a seven-foot-tall man, choose a woman?" However… Sett: Constitution Card received. Viper: Summoning Card received. Azir: Summoning Card received. Kayle: Constitution Card received. …So, I'm playing League of Legends in the Uchiha clan.

A fan group has been created; interested authors can add it on their homepage.

My name is Yun Ting, a consciousness transmigrator from Earth.

I've been transported to the Naruto world.

Unlike other transmigrators, he was not an orphan, nor was he a cultivation failure; in fact, he had a powerful grandfather.

Of course, there is a golden finger; it's a mysterious fishing space where, it's said, one can fish for anything.

There is also a choice system where different choices lead to different rewards.

My current identity is that of the Uchiha clan, the leader and representative of the hawk faction, the great elder of the Uchiha clan, and the grandson of Uchiha Setsuna.

This means that even if I have extremely poor talent, I will still be able to survive, since the Uchiha clan's elder would not starve me.

Fortunately, I do have some talent.

As for what those idiots did afterward.

I wasn't too worried. If all else fails, I'll just strike first.

A genius who hasn't grown up is nothing.

But one day, a little red-haired girl barged into her world.

They would also spread their arms in front of themselves and say things like, "Yunting is mine."

It's silly, but cute, right?

[Single female lead Kushina, if you don't like this, please leave!]

There won't be any more female leads; this is the only one.

He might interact with other female characters, but there's only one female lead!!!

Don't fixate on the timeline. I'll try my best to ensure the timeline isn't too far off, but it's impossible for it to be perfectly accurate, because some parts of the original timeline are quite illogical.
