I Just Awakened the Rinnegan, and You're Telling Me This Is One Piece?

Su Chen transmigrates to a desert and activates a ninja System.

His starting character is Uchiha Madara!

Thinking this is the world of Naruto, he decides to spend some time in seclusion inside the System's barrier and emerge only once he's strong enough!

That seclusion lasts five years!

Five years later, Su Chen awakens the Rinnegan and plans to leave seclusion, crush the Third Hokage, and have some fun being Hokage.

As soon as he opens the System barrier, Su Chen sees a man who claims to be the world's greatest swordsman.

Su Chen looks at Hawkeye and falls into deep thought.

I just awakened the Rinnegan, and you're telling me this is the world of One Piece?

"My power is enough to summon meteorites, so you'd better watch out!" Fujitora.

"Tengai Shinsei!" Su Chen.

"My power is invincible!" Green Bull.

"Wood Style: Deep Forest Emergence!" Su Chen.

"My heart will always belong to Luffy!" Hancock says through tears.

"Whatever." Su Chen pins Hancock down.
