One Piece: Build The Strongest Beast Pirates

New World, Letifre Island.

On the surface, this is just a deserted island near the Marine base, G-3, but it is actually a secret experimental base of the World Government.

Biochemistry, weapons, Devil Fruit, human experiments…

Everything is researched in this secret scientific research base.

In this secret scientific research base under the island, there are neat facilities and perfect scientific instruments.

Many of the research materials here can be regarded as black technology in the Earth.

The Pirate World is a world where technology is completely crooked.

Most of the daily necessities are still in the Middle Ages, with the means of transportation being wooden sailboats and horses on the land. 

Their primary weapons are still swords, flintlock guns, and fuse cannons.

But there are robots, clone warriors, Germa's battle suits...

At this time in the secret scientific research base.

Hundreds of scientists in white coats shuttled around as they discussed and conducted various experiments.

Of course, the protection and monitoring of CP agents and Marine are also indispensable.

Scientists, CP agents, and Marine who are busy don't know…

At the altitude of 1,000 meters above Letifre Island, a majestic Eastern dragon was carrying a man on its back as it hovered right above the island.

"Stupid brother, don't drag me back."

"Don't worry, big bastard!"

"Ugh—"

As soon as his words fell, the soaring dragon suddenly turned into a human, and then two tall figures fell directly from a thousand-meter altitude in free fall.

"Whizzing!!"

The strong wind whistled in the ears of the two figures.

"Don't let your guard down!"

"As soon as a pirate group approaches the coast, notify the G-3 immediately."

"Remember, we can't be exposed here, understand?"

"yes."

Under some camouflaged 'rocks' on Letifre Island, there is a Marine monitoring every move on the coast in all directions.

Once a pirate ship is found, the nearest marine base will be notified to destroy or expel it.

Their main task is to protect the secret scientific research base here and try not to take action if they can. Otherwise, they will be easily exposed.

"Boom!!"

"Boom!!"

There were two loud explosions on the island, and then the ground of the entire island trembled slightly, with the surrounding rocks shattering and collapsing, stirring up a thick dust.

"What happened?"

"Is it... an earthquake?"

"Go and see what happened!"

Seeing that there were no ships along the coast, the Rear-Admiral, who was in charge of security, came out with a team of marines to check the situation.

"Rear-Admiral Richard, two big holes were smashed here!"

In the center of the dense dust, a Lieutenant Commander pointed to the two large holes in the ground after the thick dust gradually settled down.

"Why were there two such big holes here?"

"Did something fall from the sky?"

Several Marines couldn't help but look at the big hole in front of them, and then they looked up at the blue sky.

Nothing??

"These two big holes...do they look like they were smashed out by a... human?"

Rear-Admiral Richard frowned when he saw the big hole that looked a bit like a 'human.'

"Clatter"

Suddenly, the sound of stones shaking and falling to the ground came from the two big holes.

"Crack--"

A group of marines immediately raised their guns and aimed at the big hole.

"What's that sound?"

"There is movement below!"

"..."

"Ah, it's quite comfortable."

Just as Rear-Admiral Richard was nervously preparing to step forward to check the situation, a thick voice suddenly came out of the pit.

"Someone!!"

"Who is it?!"

"Boom!!!"

At this moment, two big hands stretched out from the pothole, which surprised all the Marines!

"Are you... kidding me..."

"Is it really a human?"

"Someone fell from a high altitude and smashed such a big hole, but he still didn't die?"

Just when the Marines were inexplicably terrified, two tall figures crawled out of the pothole.

The huge body blocked the sun, and the shadow covered the team of Marines.

"Gudong~~"

All the Marines, including Rear-Admiral Richard, swallowed their saliva with cold sweat streaming down their foreheads as they looked at the two figures exuding a fierce aura in front of them.

"This... this is..."

"They are the remnants of..... Rocks Pirate!!"

"'Evil Ghost' Kaishu and 'Azure Dragon' Kaido!!"

"Pirate, it's an enemy attack!!"

"They fell down from the… sky!!!" 

"Quick! Shoot them!!"

After Rear-Admiral Richard got out of his shock state, he ordered loudly.

A group of marines immediately looked at Kaishu and Kaido with fear in their eyes as they quickly pulled the trigger.

"boom!"

"Bang bang bang!!"

"Clang clang—"

The bullets shot into their body, but it was like hitting a steel plate. It deformed and fell at the feet of the two of them after creating a sound similar to iron objects colliding against each other.

"Um?"

Only then did Kaishu look down and notice these 'little bugs.'

"Annoying lackeys, don't get in my way!"

Kaido looked disgusted, and his relaxed muscles tensed up as he swung his mace in front of him.

"Boom!!"

"Ahhh!!!"

"Wow..."

The next moment, the group of marines were all killed by Kaido’s one attack, except for Rear-Admiral Richard.

He used the 'Iron Body' in time. Although his feet plowed several meters on the ground and his head was bleeding, he was not knocked down!

"Hoo hoo...Damn pirate, don't underestimate me, I'm..."

"Thunder Bagua!"

"Boom!"

With another attack, Richard, who hadn't finished speaking, was directly sent flying.

With a bang, he smashed several big rocks and fell to the ground while bleeding from his seven orifices.

Just looking at the distorted and limp body, one could tell that all the bones in that body had basically been broken.

"Too weak!"

Kaido rolled his arms as he didn't even finish warming up.

"Let's go, Kaido; the support from the G-3 should be coming soon. We need to find someone quickly.”

Kaishu's observation haki has already sensed the location of the scientific research base.

That being said, Kaishu and Kaido's footsteps are unhurried, and there is no fear that reinforcement will soon come here.
