......

In 1520 of the Sea Calendar, the Battle of Marineford broke out, and the Yi Chen Grand Fleet descended from the sky, surrounding the entire navy.

Crocodile: Boss, did you have to make such a cool entrance?!

Empress: I will protect Brother Chen's will!

Hawkeye: You want me to go easy on you? Five duels and three bottles of homemade wine!

Ming: Young Master Chen, let's cause a huge ruckus together!

Big Bear: How can we make the acting more realistic? Ah Chen is making things difficult for an honest person!

Moonlight Moria: ......

Admirals: Turn your guns around! The time has come to swear allegiance!

Su Yi transmigrates to the world of One Piece and becomes the supreme Celestial Dragon.

I thought I had a perfect start, but I found myself to be a useless piece of trash, so weak that I would pant after walking just a few steps.

With Straw Hat Luffy about to set sail, the Revolutionary Army's anger is burning, the Celestial Dragons' "good days" are coming to an end, and he could become cannon fodder at any time.

In this moment of despair, the [Great Dao Demon Cultivation System] was finally activated!

Since Heaven won't grant it to me, I'll take it myself!

Since the righteous path is difficult to follow, then let us prove our path through demonic means!

To refine the [Innate Demonic Marrow Pill] that can defy fate and change one's destiny, one needs the brain marrow of one hundred "hundred-man slayer" villains.

Simple!

Su Yi, in the name of a Celestial Dragon, issued a single order and marched straight to Impel Down, the underwater prison.

"I want to 'borrow' one hundred of the most vicious prisoners to be my new 'toys'!"

Does cultivating demonic techniques require a highly wicked person as a catalyst?

Isn't this simpler?

Aren't all the Celestial Dragons in the Holy Land just like that?

[Job Change + Necromancer + Undead Scourge + Decisive Killing + No Love for Women + Unstoppable Push + Fun Cheat Codes]

During the awakening ceremony, Lin Mu was mocked as the "most useless special class"—the necromancer! His summoned skeletons were incredibly fragile, and his own body was as thin as paper. He was ridiculed by [Flame Warrior] Wang Hao as a "moving experience pack," who vowed to "crush" him in the dungeon!

However, no one knew that Lin Mu's soul had transmigrated here, and he came with an incredible cheat code!

Talent: [Description Tamperer] (Black, Unknown Level)! [Ability: Modify "one word" in the target's description!] In an instant, the world changed in his eyes!

Skill [Resurrect Skeletons]: "Quantity Limit: 1"? Modified → [Quantity Limit: 9]!

Staff: "10% reduction in mana cost"? → [90% reduction in mana cost]! From trash staff to god-tier gear!

Skeleton Soldier: "Inferior Bones"? → [Superior Bones]! Health, Attack, and Defense all increase fivefold!

Faced with Wang Hao's provocation, Lin Mu sneered: "A friendly spar? Are you sure?!" Only when nine indestructible skeletons surrounded Wang Hao did he kneel down in despair, begging for mercy in terror!

The BOSS Goblin Shaman can resurrect minions infinitely? And he even knows fire magic? Lin Mu smiled: "Can use fire magic? Modified → [Cannot use...]!" The BOSS was completely dumbfounded and at Lin Mu's mercy!

Monster throwing stones? → [Cotton Block]! Poison gas trap? → [Scent Trap]!

He altered the descriptions of everything, overturned the rules, turned the rotten into the magical, and made the impossible possible!

Congratulations to professional Lin Mu for obtaining the unique title:

"How many flights of stairs do you have to carry a bag of rice up? How many flights of stairs do you have to carry a bag of rice up? How many flights of stairs do you have to carry a bag of rice up?"

Pain spread his arms, overlooking the entire panorama of Konoha, high above like a god.

Unbeknownst to him, right behind him, Hinata floated there like a ghost, quietly watching him.

I've been transported to the Dragon Ball world and become the protagonist, Son Goku, starting with the Dragon Ball System.

The stronger the protagonist, the stronger the Dragon Balls become.

Frieza: I... I've turned into a pig!

(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.

Kobayashi unexpectedly falls into the world of Hunter x Hunter, and the "Analysis Record of Abilities Across the Heavens" appears out of thin air in his palm—this cheat code turns the Hunter x Hunter world into his first step in unlocking the myriad realms. Without divine power bestowed upon him, how will he use the Nen abilities of Hunter x Hunter as bricks to build the foundation of the Super God Academy's genetic system, brick by brick? Will he temper his will with a burning passion, or use "Enju Renfu" to control the flow of ki, paving the way for gene activation? The four-year deadline is fast approaching: to grow into a high-level combatant capable of participating in the Chimera Ant King's final battle, and to survive the Chimera Ant arc with its sky-high mortality rate, he must unlock interdimensional access. What sparks will fly when his Nen collides with the Super God genes? And can he survive the terrifying pressure of the Chimera Ants and take the first step on his journey across the heavens? New author, new book, please collect and recommend!

I possess the Hand of God, capable of copying any ability. I possess the Hand of Demons, capable of summoning the power of demons and gods. I possess a pair of divine and demonic hands, capable of kicking Madara, punching Kaguya, and overturning the entire Naruto world!

He was transported to Konoha and became a member of a 'pyramid scheme', the Fire Will teacher (genin).

As the graduation of the ninth graders approached.

Memory awakens; complete tasks in the 'Teaching and Educating' system to receive rewards.

Devil Fruit: Glint-Glint Fruit.

In order to gain greater power, he accepted the system's advanced mission.

After Kakashi became Kakashi Hollow, Cangwu became the Jonin instructor of Team 7.

Cangwu receives a reward for every improvement made by Class 7.

What?

Are these teachers at the ninja academy?

Come here, tell me!

One-Punch Susanoo with a Great Buddha... You're saying he's a teacher?

Cangwu: "Have you ever been kicked at the speed of light?"

Kurenai Yuhi: "You brat, don't think you can get on top just because you've gotten stronger!"

Hinata: "Cangwu-sensei...you're so mean~"

......

Do you believe in light?

Kaguya Otsutsuki: "Don't come any closer!"

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.
