In the underground magma lake, boiling magma continuously released massive bubbles, spraying magma rain everywhere.
Caesar, clad in pitch-black battle armor with golden wings spread wide, hovered above the immense crimson magma lake, coldly watching Imu, whom he had blasted deep into the magma.
Unbeknownst to him, in the few short minutes of their battle, something had happened on the seas of the New World.
High in the sky, over ten thousand meters above sea level and more than fifty miles from the core of the battle, a large chunk of soil floated.
Shiki, Fujitora, Shanks, and over a dozen others crowded on it, staring dumbfounded at the sea below.
Shanks' eyes were wide, his face utterly disheartened.
"This... this kind of power, can humans really possess it?"
Shiki's throat moved as if he wanted to say something, but in the end, he only let out a long, heavy sigh.
As for Doflamingo, Crocodile, Yasopp, and the others, they had long been numb.
Looking down from ten thousand meters high, when Caesar kicked open the sky and smashed Imu into the sea, the point of impact became the epicenter.
Ring-shaped waves radiated outward in all directions, as if a comet had crashed into the ocean.
In an instant, towering waves reaching over a thousand meters high surged violently, sweeping across the other seas of the New World!
From a bird's-eye view, the surface of the New World appeared wrinkled, with waves layering upon waves.
Everything in their path was submerged by the kilometer-high tsunami!
Within minutes, the tsunami's crest engulfed the entire New World, even impacting the Misty Sea.
The millennia-old fog shrouding the Misty Sea was instantly blown away by the tsunami, revealing the region to the sky once more.
Dozens of islands in the Hachinosu Sea were utterly defenseless, instantly submerged by the tsunami, claiming the lives of millions!
Even Tottoland, over a thousand miles away, was caught in the terrifying tsunami, submerging island after island.
Wano Country, located at the center of the four seas, was also engulfed by the colossal waves.
The remaining citizens drifted helplessly, desperately struggling against the overwhelming tsunami.
Fish-Men, highly sensitive to disturbances in the sea, immediately detected the abnormality.
Thus, Neptune promptly prepared to counter the tsunami's impact.
Simultaneously, for the sake of his allies, Neptune dispatched over a hundred thousand Fish-Men to Wano Country to rescue the affected citizens.
Not far from Tottoland, over a dozen large ships crowded with five to six thousand pirates watched in horror as the overwhelming tsunami rushed toward them.
Katakuri's expression turned grave. His first instinct was not to confront the tsunami head-on but to ensure survival.
Joining forces with Perospero, they used their abilities to create massive amounts of mochi and candy, swiftly encasing the ships to withstand the impending impact.
The Red Line, where the Holy Land Mary Geoise stood, trembled from the earth-shattering shockwaves.
Cliffs measuring tens to hundreds of meters broke off and plummeted downward.
At the foot of the Red Line, over a million Revolutionary Army soldiers had already lost more than half their numbers.
Blood converged into rivers, flowing incessantly into the seas around Sabaody, dyeing the waters red for dozens of miles.
Dragon and the others continued to fight desperately.
Following the terrifying bioweapons known as the Seraphim, dozens of powerful figures hidden within CP0's first sequence also descended en masse.
These individuals were either high-level combatants directly trained by the World Government or former notorious pirates recruited under various circumstances.
Even the weakest among them far surpassed the strength of a Vice Admiral!
With their addition, the battle grew increasingly intense and brutal.
Had it not been for the Revolutionary Army soldiers being battle-hardened elites, each steadfast and fearless, such casualty rates would have caused morale to collapse instantly, leading to a total rout.
Amid the battlefield, Dragon manipulated storms that connected heaven and earth, displaying his formidable mastery over the Power of Rules as he single-handedly held off over a dozen Seraphim.
On the other side, a newly arrived super-powered reinforcement, whose combat prowess was even more exaggerated than Dragon's, single-handedly suppressed and slaughtered over a dozen top-tier fighters.
"Zehahaha, a bunch of trash who haven't even touched the edge of the Power of Rules. Who gave you the courage to face me?"
Black currents swirled around Rocks D. Teach, pulling enemies toward him as blue flames absorbed damage.
The Tremor-Tremor Fruit shattered the atmosphere, causing over a dozen elite CP0 agents to pale in terror.
"Dark Vortex!"
Teach spread the fingers of his left hand, a whirlpool of black energy spinning in his palm, yanking the nearest CP0 agent toward him.
This agent was clearly a top-tier fighter with strength comparable to an admiral, remaining calm in the face of danger.
Even while suspended in mid-air, he swung his peculiar longsword, unleashing a hundred-meter-long blade of light directly at Teach.
The strike was so close that Teach had no chance to dodge.
"Hahaha, die! Blackbeard Teach!"
The man laughed triumphantly, filled with pride.
Yet Teach completely ignored the blinding slash.
Clenching his right fist, he unleashed a white shockwave that struck the air from over ten meters away.
Crack, crack.
The air fractured like glass, followed by a terrifying shockwave that poured forth, completely engulfing the man.
"Arghhh!!"
The CP0 admiral-level fighter let out a blood-curdling scream as layers of flesh were torn from his body under the storm-like impact.
In mere seconds, he was reduced to a bleached skeleton that fell from the sky, scattering into broken bones.
Meanwhile, the hundred-meter slash that had cleaved through Teach's chest was instantly healed by the blue flames burning across his body.
This horrifying scene made the dozen distant top-tier fighters turn pale.
"Impossible! Whitebeard's Tremor-Tremor Fruit couldn't possibly be this powerful!"
"Right! I've fought Whitebeard before. Though I was no match for him, even Whitebeard at his peak couldn't one-shot an admiral!"
The terrifying combat power displayed by Blackbeard left the CP0 experts trembling with fear, hesitating and unwilling to advance.
Suddenly, one expert's head exploded with a sickening crunch, splattering blood and brain matter on those nearby.
The voice of the Gorosei echoed from an unknown location.
"Kill him, or you will die."
"Damn it! Attack together!"
The remaining admiral-level fighters ceased their hesitation and charged simultaneously.
Suddenly!
A world-shaking explosion roared from the distant horizon, causing the air to tremble and churn like turbulent water.
Immediately after, the towering Red Line—tens of thousands of meters high—began to quake.
Massive rock walls crumbled and fell, crushing Revolutionary Army soldiers and World Government forces below into pulp.
Sensing the tremors resonating through the air, the arrogance vanished from Teach's face, replaced by sheer terror.
He stared up at the towering Red Line, as if trying to discern who was fighting.
"What kind of powerhouse is battling there? This is absolutely terrifying!"
