The pattern took the shape of a pentagram.
As the pattern appeared on the battlefield, streaks of black-and-red lightning kept shooting outward from the center of the pentagram.
The lightning continued to multiply, and the overpowering aura above it gradually intensified.
Centered on the pentagram, this formidable aura swept across all of Brown Square.
Until it bore down on the entirety of Krusimia Island.
The sky darkened in that instant as well.
Many people felt this powerful aura.
Sabo was no stranger to this aura, because he had felt it not long ago.
"Are you going to appear too? But why is this aura so much stronger than before?"
Of course he knew what this aura represented.
But it was considerably stronger than what he had witnessed before.
He spoke in disbelief. "Could it be that they weren't using their full strength before? That's terrifying! Combined with that special ability of theirs, they'd practically be invincible."
He looked up at the sky and murmured, "Mr. Lott, this isn't good. How are we going to deal with this?"
Vegapunk turned toward Sabo and said, "I remember you saying you were captured because of them, right?"
Sabo did not turn around. Instead, he kept his eyes fixed on the mysterious pattern that had appeared on the battlefield, then nodded.
"Conqueror's Haki? What is this thing?" Luffy was closest, and feeling that powerful aura, he could not help exclaiming in shock.
This was the first time he had encountered someone whose Conqueror's Haki appeared before they did.
"What powerful Conqueror's Haki!" Ace was equally shaken.
Because this powerful Conqueror's Haki was practically among the strongest he had ever witnessed.
Across from him, Kalon Banbu stopped what he was doing. Beads of cold sweat appeared on his face, and his whole body trembled slightly.
