The vast battlefield was swept by swirling, backflowing sand and dust.
As they looked at the stretch of ruins that had been smashed out by sheer force, quite a few people present changed expressions slightly.
Even Tsuru and Sengoku were no exception.
Only Garp frowned deeply, staring fixedly at the ruins below.
"Cough, cough. I told you, sneak attacks are bad, but you just had to make a move."
"Now that I've given you two moves, from here on out, even if no referee calls the start, this is an official battle."
Luffy's voice suddenly rang out.
The dust permeating the area first froze in place. Then, an immense aura erupted like a raging tide.
The suspended dust filling the sky was directly blown away by the released aura.
It revealed Luffy, who had been shrouded within the dust, completely unscathed as he held down the straw hat on his head.
The immense Haki continued to sweep outward with undiminished force, covering an area within a thousand meters.
Bang! Bang! Bang!
The sounds of heavy objects hitting the ground rang out one after another.
To make room for the wagered battle, the Marine soldiers who had gathered to watch had voluntarily cleared out a thousand-meter-wide open space.
However, as the battle heated up, some soldiers had clearly edged closer without realizing it.
Now, slightly caught up in Luffy's fleeting burst of Conqueror's Haki, they rolled their eyes back and collapsed unconscious.
"Th-this is Conqueror's Haki, the mark of a king found in only one in a million!"
A Marine officer was the first to lose his composure and cry out.
Looking at the hundreds of Marine soldiers who had been swept aside, the pupils of the Marine soldiers and officers present visibly contracted.
Even Akainu and Saint Ethanbaron V. Nusjuro
