The Warmongering System Has Gained Sentience

Wang Xier accidentally transmigrated into a parallel world of One Piece, where he unexpectedly became a Celestial Dragon.

In this world, Roger was still alive, and so were Rocks and Kozuki Oden... In a place crawling with powerful figures,

he obtained a System with an utterly unremarkable name. But as he fought more and more battles, he discovered that the System had actually developed a will of its own! It grew more and more unhinged,

and the abilities it occasionally gave him were frightening even to himself! One careless move could cost someone their life,

leaving people across the Four Seas on edge, terrified of receiving a challenge letter from him.

Rocks: "If I'd managed to withstand his third move that day, that brat Kaido might not have died!"

Roger: "I don't deserve the title of Pirate King! It should belong to Xier!"

Dragon: "If he ruled the Celestial Dragons, the Revolutionary Army could disband!"

Kozuki Oden: "Saint Xier, I lost! And a bet is a bet. My son is yours to do with as you please!"
