One Piece: I Became a Legend by Seeing Proficiency

"What's going on?"

Near Fish-Man Island in the New World, a tsunami smashed nearby ships to splinters. The pirates aboard couldn't help cursing.

The New World's weather was bad enough. Now a tsunami like this had them furious, swearing up a storm.

Deep beneath the sea, the moment that soft laugh reached the Sea Kings' minds, the creatures nearly lost their wits.

But the Sea King that had lived for over a thousand years quickly calmed down, drawing on its experience and strength.

"Don't panic! Stop, all of you!"

Kentauros's authority carried weight. The other Sea Kings soon settled down.

The turbulence gradually subsided.

"Who are you?"

After a brief silence, another vibration came through. It was infrasound, too low for humans to detect. Ordinary people could not hear the Sea Kings speaking.

"You were just talking about me, weren't you?"

Dongze's voice reached them at an unhurried pace. At the same time, he rapidly marshaled every power within him.

Armament Haki, Conqueror's Haki, and, of course, Observation Haki. The Voice of All Things granted by the last of these was what let him speak with them.

At his reply, nearly twenty pairs of eyes instantly fixed on the ship sinking toward the seafloor.

The pressure exerted by beings on another level of existence hit Robin in full force. Her legs suddenly went weak.

Dongze frowned. He strengthened his Conqueror's Haki, pulled Robin behind him, and shielded her.

"Look away!"

His cold command rang through the Sea Kings' minds, edged with a biting chill. This time, Dongze made no attempt to conceal his Conqueror's Haki.

The sea, which had just gone still, churned once more. This time, Dongze alone had stirred it.

His violent Conqueror's Haki struck like an air cannon. The resulting gale even whipped up a rising waterspout.
