He drew his sword, Qiu Shui, and pointed it to the sky. "But cutting it one by one is too troublesome. I developed a few new moves while fighting that old blind man, so I can try them out all at once."

Kuro pointed the blade at the sky for a moment, then sheathed Shusui.

Click.

"Secret Technique: Psychic Blade: Azure Dragon Rain".

Sizzle!

The red demons, battered by the rain, seemed to have encountered some kind of dense cutting machine. Their bodies were suddenly disintegrated and cut open, either into pieces or covered in blood, and were smashed into a bloody mess.

Thousands of red demons were transformed into a bloody hell within the walls.

Kuro used seawater in conjunction with his ultimate technique to attack his opponent. He had used this technique before when he was dealing with Teach. This time, he just refined one aspect of it.

Kuro didn't have many methods to deal with a large number of beings before. Before he gained his powers, he only had 'Crushing Pressure'.

For ordinary people or the weak, the murderous aura emanating from the 'collapse pressure' is enough.

He had never had the chance to encounter a group that was even slightly stronger than his before...

Back in the East Blue, he had never encountered a pirate crew with more than a thousand members. Most pirate crews had a few dozen to a hundred members, with larger ones having two or three hundred, and five hundred at most.

What? You mean 'Eastern Sea Admiral' Kleek?

He's so unlucky.

As for the Grand Line, try gathering a fleet of several thousand people in the first half and see what happens.

Either you get surrounded by the navy and used as a target, your ship is blown to pieces by cannons, or a few colonels from headquarters, like T. Penn, come and slice a ship to pieces with a single blow, and the game is over.

What? Pirates are all super strong?

That kind of new world.

The first half of the story doesn't have those groups of thousands or tens of thousands of people, with each ship carrying several pirates with bounties in the tens of millions.

The Navy Headquarters is located on the Grand Line. If they could gather this kind of force in the first half of the line, the Navy might as well go home and farm.

Only pirates who have already established a powerful force in the New World have the ability to gather troops.

Kuro had never encountered a large-scale attack in the East Blue, and after gaining his powers, he was no longer afraid.

If they're on a slightly larger scale, they can just throw an island at you. If that doesn't work, they can just roll up the place you're standing on and throw it into the sea. If all else fails, they can fly back to get reinforcements themselves.

But this was too monotonous, and fearing something might go wrong, Kuro kept looking for other methods.

This time in the West Sea, we finally found a few.

The Psychic Blade - Fighting Lion can be used against larger and stronger pirate crews.

The Psychic Blade - Azure Dragon Rain is used to deal with elite pirate crews.

The power of raindrops is equivalent to the power of a knife; rain is like raining knives, and it is much more powerful than ordinary swords, after all, it is mixed with his Azure Dragon Secret Technique.

'Fighting Lion' would have been enough to deal with these red demons, but they are too scattered and it's not safe. What if they are blown too far away and don't die?

Kuro could use it to test out his new trick.

As for the effect...

Kuro stroked his chin, looked at the flesh and blood scattered across the earth, and nodded, saying, "It works quite well."
