This Navy Is Clearly Overpowered, Yet Far Too Cautious

Yi Yan accidentally transmigrates into the world of One Piece and obtains a System, along with the power of Gildarts, Fairy Tail's strongest mage: Crush magic.

With such an overpowered start, the System expects its Host to make a big splash. Instead, Yi Yan chooses to keep a low profile and build up his strength. And he keeps at it for ten whole years.

Big Mom: "Let me catch that brat, and I'll eat him alive!"

Kaido: "You think hiding at Marine Headquarters will stop me from coming?! You little brat! Come out and fight me one-on-one!!"

Whitebeard: "Is this kid... a little too cautious?"

Shanks: "..."

System: "You're way too timid. If I could kill my Host, I'd have killed you a hundred times by now!"

Yi Yan: "I'm not timid. I'm just cautious!"

"My motto in life is: if I can win by doing nothing, I absolutely won't carry the team!"

"Being bold might make you a profit, but playing it safe never loses!"
