Seafaring: The Strongest Navy, Starting with Simplified Skills

He transmigrates to the world of One Piece and becomes a marine soldier.

A soldier who doesn't want to become a general isn't a good soldier! Kong Long wants to become an admiral, and even Fleet Admiral.

The Simplification System awakens:

Simplified Marine Six Powers training method: Breathe!

From then on, breathing alone can increase the power of the Marine Six Powers!

Simplified Three Types of Haki training method: Lie flat!

From then on, simply lying in bed can increase his Haki training progress!

Other people train until they're exhausted, and still might not learn the techniques. Kong Long only needs a moment to master them and unleash them with ease!

Without even realizing it, he grows stronger and stronger...
