Naruto System in One Piece - Chapter 511

Xuan Yi was transported into the fictional world and became an elder of the Black Sword Sect! The moment he entered the world, he was at the Sea-Splitting Rank!

A pill, a tiny capsule encased in a biologically harmless water-soluble shell; A shell whose very existence is a result of a century of research and technological advancement. A manmade synthesis of Chemicals and product of complex processes.

And in the end, a means to an end.

A way to deliver a concoction of other Chemicals for an agenda; Vitamins for nutrition, medication for treatment, or… perhaps more.

We trust that what we eat won’t do us harm, and trust that those who are responsible for its creation had the best of intentions. But in the end, it is difficult or perhaps impossible to truly tell what lies within a pill.

That is until one day I entered a research institution as a test subject. All I did was swallow a pill I was told to be a health supplement.

I am the sword.
Killing a man amidst a thousand miles, no one dares take ten steps.
Killing a man amidst a thousand miles, no one can take ten steps.
Killing a man amidst a thousand miles, ten steps? Not possible!
I am the sword, the sword is me,
On the path towards heaven, each shall wield their own.
