Naruto System in One Piece - Chapter 34

A story about a weak, small larva with a human soul, who travels all the way to become the ruler of the stars.

In the endless Universe is eight primordial laws. Each of the eight laws have been fused with a supreme expert, but unbeknownst to everyone, there is a ninth law in the universe. It tears open the Primordial Chaos and is beyond reach.
