Devil Fruit Era: My Full Level Armed Color Emission

Ye Chi traveled to a world that resembled an urban version of One Piece!

There are Haki, Six Styles, Swordsman, and Devil Fruit. The only difference is that everyone needs to enter the Devil's Space to gain the Devil Fruit ability when they are eighteen years old!

Ye Chi possesses a hundred-fold amplification system and starts with full level Armament Haki! Buy any knife and upgrade to Yama in the blink of an eye! Awaken to see, hear, and listen directly to the sounds of all things!

Conqueror's Haki, after amplification, can actually wrap around the attack!

These are not over yet! When he acquires the Devil Fruit ability, he suddenly discovers that the fruit's abilities can also be strengthened! Who can withstand the Devil Fruit's ability that has been increased hundreds of times? !
