One Piece: My Zanpakuto Can Vaporize the Sea

[One Piece Fan Fiction + Most Evil Marines + Ideological Dimension Reduction + Ruthless and Decisive + Soul Reaper System + Revolutionary Mentor + Unstoppable Domination]

After transmigrating into the world of One Piece, Wang Teng awakens the Soul Reaper Legacy System and gets Ryujin Jakka from the start.

In a world where water counters every Devil Fruit, Wang Teng looks at the blade in his hand and smiles.

“Pirates fear seawater? What a coincidence. My blade… can boil the entire ocean!”

During the Paramount War, Whitebeard unleashes a towering tsunami, ready to drown Marineford.

Aokiji is just about to freeze the sea when Wang Teng steps out from the crowd and slowly draws the katana at his waist.

“Rend all creation to ash!”

He swings once, and a wall of fire stretching from heaven to earth vaporizes the tsunami into a vast cloud of mist! The whole world is stunned!

Akainu roars in fury: “Wang Teng! You stole my spotlight! Take this, Great Eruption!”

Wang Teng bats away the magma with a casual normal attack and sneers: “Sakazuki, your magma… is too cold.”

He slaughters pirates, tramples the Celestial Dragons, and establishes the Neo Marines.

He meets Monkey D. Dragon in secret late at night, tosses him a copy of The New Era Manifesto, and brings Dragon to tears as he cries, “Now this is a true revolution.”

When the Five Elders activate the Ancient Weapon and Imu tries to drown the world,

Wang Teng stands atop the Red Line and releases his Bankai: Zanka no Tachi.

“A sun with a temperature of fifteen million degrees. Can you… withstand it?”

Even Luo is mentioned!
