Starting with the Mangekyo Sharingan: Rampaging Through the Fourth Great Ninja War

Transmigrated to a deserted island in the world of One Piece.

Yu Nan was granted two Mangekyo Sharingan by the System from the start.

Faced with the threat of giant beasts on the island and Sea Kings in the ocean, Yu Nan took caution to the extreme.

After years of training and rewards from the System, Yu Nan finally mastered the Mangekyo Sharingan and all kinds of advanced ninjutsu.

The Worst Generation? Can you handle a Rasengan?

They say Kaido, the strongest creature, can take a beating? Take this Night Guy head-on!

What the hell are the Five Elders? Just five old bastards who refuse to die.

The Empty Throne, Imu? So you're the one they call the ruler of the world?

The Summit War? I'll kill everyone I meet!
