Seafaring: Building Weapons in the World of One Piece

After transmigrating into the world of pirates, Xiao Cheng uses a System to build guns and cannons.

Devil Fruits versus modern weapons.

Kizaru: Have you ever seen a light-speed kick?

Xiao Cheng: Have you ever seen a close-in weapon system that fires thirty thousand rounds per second?

Kaido: I have the strongest defense.

Xiao Cheng: I wonder how many missiles you can take.

When a mushroom cloud rises over the Red Line, Akainu learns how the world works: the Five Elders can serve tea and water, and Imu can dance to “Extreme Happiness Pure Land.”

Everyone: I don't know why, but that mushroom cloud feels strangely familiar.
