The Completely Shattered Rule of the Four Emperors!

Facing BIG MOM as she bore down like Mount Tai collapsing overhead, Luffy, transformed into a black-gold giant, violently kicked off the crumbling ground with both legs. The earth caved in with a thunderous crash, as if struck by a magnitude-ten earthquake!

His enormous right fist, wrapped in near-solid black-gold Haki and coiled with countless violent black-red bolts of lightning, shot forth like a God Slaying cannonball fired from its barrel, crashing head-on into BIG MOM's world-destroying fist!

"Gomu Gomu—Black-Gold King Kong Gun!!!"

"BOOM!!"

At the very instant those two terrifying iron fists—one representing the Old Era Overlord, the other the gods and demons of the New Era—savagely collided in midair!

They did not touch!

Within the narrow gap of mere centimeters between their fists, two incomparably violent bursts of Conqueror's Haki clashed in a final crushing struggle, like cosmic beasts tearing into each other with the force of a supernova explosion!

Time and space seemed to freeze completely at that moment!

All sound vanished from heaven and earth, and then—

"CRACKLELELELE—RUMBLEEEEE!!!!"

An unparalleled explosion capable of shattering everyone's eardrums swept across the entire Totto Land sea like a burst galactic river!

The terrifying Conqueror's Haki collision became a circular shockwave of dark red and black-gold, stretching over dozens of kilometers wide!

Everywhere the shockwave passed, the already ruined cream castles, candy forests, and biscuit mountains of Cake Island were ruthlessly erased by an invisible primordial hand, instantly reduced to fine dust!

Black-red and gold-black lightning filled the sky like wildly dancing dragons, rampaging through this Lightning Domain and forcibly tearing the heavy thunderclouds in the sky into two perfectly smooth halves!!!

When two Emperors clashed, the sky split apart!

"Old hag!!!"

Veins bulged across Luffy's black-gold face. Gritting his teeth against the terrifying pressure on his fist, as though
