The Pirate World Is so Scary

The era of great pirates is turbulent, strong men fight on the sea, new strong men emerge in endlessly, and old overlords are constantly falling. The legendary four emperors may have suffered at the hands of bandits, and the heroic lieutenant general would have been disemboweled by an axe. "This world is really scary. I just want to live until I retire." David Carr looked at the pirates appearing in the distance, and inexplicable fear filled his chest. So... "Fill me with all the shells! Pacifists move out quickly! Power rock carpet bombing!" "Where's the anti-tank gun! Bring the grenade launcher up quickly. Why hasn't the Barrett sniper blown off the enemy's head yet?" "Don't stop the Gatling gun over there. Help me delay. Even if the opponent is Whitebeard, so what! Wait until I roll out a nuclear bomb and kill him!" "As long as I kill all my enemies, I will be absolutely safe!" ....... Not following the ship, the protagonist is in the navy camp, I don't know the original plot, but I have a general understanding of One Piece. I'm really scared, but I'm not afraid! Don't like to enter by mistake.
