Sailing the Seas: Switching to Gunslinger from the Start

After transmigrating into the world of One Piece, Tang Ge is kidnapped because he's just too handsome.

Just as he's about to be led onto the auction block, his golden finger arrives.

He obtains a Gunner System from a disconnected city and a band of weakened warriors.

Pirates? Don't mess with me, or this anti-tank cannon might sink your ship to the bottom of the sea.

Celestial Dragons? I'll blow up your hometown with a quantum bomb and bring world peace to your doorstep.

Marines: "This man has the power to attack a country all by himself, and even destroy the world."

Four Emperors: "Tang Ge, let's talk this out. Could you point that cannon somewhere else first? I'm scared."

Everyone in my firing range must abide by the justice I have established!
