One Piece: My Dumb Brother Makes Me Invincible

Loge, an ordinary man, transmigrated into the dangerous One Piece world with one goal: to be a salted fish, avoiding all conflict. But a fateful lightning strike revealed a horrifying truth – his new name was Rocks D. Gel, inheriting the bloodline of the world's greatest demon, a name that sends shivers down the spines of the World Government! Just as despair set in, a bizarre System activated, binding him to his new \"brother\": Edward Weeble, the monstrously strong, yet simple-minded \"Whitebeard II.\" Their lives are now linked, and Loge gains a tenth of Weeble's terrifying power, along with unique skills and a seastone revolver. Now, this reluctant heir to chaos must drag his overpowered, loyal giant through a world gunning for his very existence. Can a man who only wanted peace truly embrace a destiny that threatens to shatter the entire ocean?
