My System Rewards Me with Max Defense, and I Took So Many Hits I Became a General

After transmigrating into the world of One Piece, Ulysses Dunn finally managed to activate his System.

But he discovered that although the System's rewards seemed random, they were all defensive in nature!

And so...

"Colonel Dunn stopped the Seven Warlords' Crocodile all by himself!"

"Rear Admiral Dunn stopped the Emperor Kaido all by himself!"

"Vice Admiral Dunn stopped the Big Mom Pirates all by himself!"

At Navy Headquarters, the Marshal and the three Admirals stared at the intelligence reports before them, lost in thought. Maybe... they should nominate Dunn for Admiral?

At the Summit War, looking at the Whitebeard Pirates charging toward him as if they didn't care about dying, Dunn said helplessly, "I'm really only good at defending!"
