One Piece: My Shadow Army and the Twelve Divine Guardians

Ye Chen transmigrates into the era of Rocks and becomes cannon fodder on the battlefield at God Valley, his life worth less than a blade of grass.

In this insane age, where Conqueror's Haki users are everywhere and Admiral-level fighters roam the land, the only things he can rely on are the Shadow Kingdom that comes with him and an ancient dial capable of finding "God's Chosen."

Rocks' legend has already come to an end, while Roger's era has yet to begin. In this power vacuum, he quietly establishes his own order:

A navigator of incredible speed charts the ends of the world for him; an explosive scientist forges invincible ship armor for him; an undying explorer lifts the veil shrouding the Poneglyphs!

When the twelve companions bound by fate gather, Ye Chen stands before the throne. He can raise a glass with Whitebeard, and he crushes Golden Lion's ambitions beneath his feet.

Only when Roger ushers in a new era on the Execution Platform do people realize in horror that the man emerging from the shadows, together with the twelve figures behind him, has long since become the one and only supreme ruler of these seas!
