Pirates: Top Armed Colors

Without Devil Fruit, is it impossible to become a strong person? I don't have a Devil Fruit either, but I have the Haki system. If I upgrade my Haki, practice my physical skills with all my strength, and rely on the ultimate Navy Six Styles, I can become one of the emperors who dominate the ocean! Physical skills are the most powerful trump card for sea survivors. I don't need a Devil Fruit. I can crush the so-called big pirates like you with a pair of iron fists and a strong body. I am the new emperor who has inherited the combat power of the old era! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
