One Piece: Start as a mythical beast, practice to become stronger.

The moment they entered Impel Down.

Jin and Tengetsu looked around with barely restrained curiosity.

Amidst the solemn and heavy atmosphere, their gazes shone with the excitement of explorers setting foot in an unknown territory for the first time.

This was the legendary prison, a place shrouded in mystery.

And they were fortunate enough to glimpse this mysterious place under the guise of escorting prisoners.

Along the way, they passed through several levels of the prison, each with its own distinct style.

Level 1, the Crimson Hell, held prisoners whose crimes were not so severe.

Outside the cells was a large "Sword Tree Forest," where prisoners would run back and forth, chased by poisonous spiders and guards, ultimately being cut by the leaves and grass until they bled profusely, enduring constant torment.

Level 2, the Beast Hell, housed various ferocious beasts and monsters.

The prisoners confined to this level knew they would eventually become food for the beasts, and didn't even have the strength to be afraid.

Level 3, the Starvation Hell, was incredibly hot due to the heat rising from the scorching hell below, coupled with the torment of being deprived of water and food, leaving the prisoners in a half-dead state.

Level 4 was the Scorching Hell, where the entire level's temperature was extremely high, like a giant iron pot filled with boiling pools of blood and seas of fire. Prisoners were scorched here to disinfect them before entering the prison.

Level 5 was the Freezing Hell. Prisoners confined to this level were in an environment colder than a large ice storage, suffering severe frostbite until death.

Level 6, the Infinite Hell, was Jin and the others' destination for escorting prisoners.

The criminals held here were monstrous pirates who were too vicious and had been erased from history. The prisoners on this level were almost legendary figures.

However, most of those imprisoned were devil fruit power users with heinous crimes. The government didn't want the abilities of these people to appear in the world too early, so they could only imprison them until they died.

"......"

Walking on the spacious central avenue, the group's steps were even and resounding, but their eyes were constantly moving, observing every detail around them.

In this place full of mystery and authority, the marines' curiosity was fully aroused.

Although they were here to carry out a mission, this unexpected "adventure" gave them great satisfaction.

When the gate to the sixth level slowly opened.

A gust of cold wind mixed with moisture swept over them. Jin and the marines stepped into Impel Down's sixth level, and they immediately felt a completely different atmosphere from the upper levels.

There was no brightness or vitality of the upper levels, replaced by a chilling gloom and deathly silence that made people palpitate.

Looking around, only dim red lights were faintly projected on the walls, creating an unsettling atmosphere.

The walls were made of rough black stone bricks, and a chill permeated through the cracks.

The corridor appeared unusually narrow, with continuous iron doors on both sides, covered with rust, and faint noises coming from inside from time to time, as if something was secretly peeking.

The steps of the guards escorting Barrett became exceptionally slow at this moment, each step appearing exceptionally cautious.

Their breathing was exceptionally clear in this silent space, and even the air seemed to stop flowing in this place.

Although they had worked in Impel Down for a long time.

They still couldn't adapt to the enormous pressure that these criminals in the sixth level brought them.

Everyone unconsciously held their breath, as if afraid of breaking the fragile peace here.

After passing through a dark passage, they arrived at an open area. The light here was even dimmer, and in the center was a circular open space surrounded by high observation platforms.

In the center of the open space was a recessed ground, surrounded by some unidentifiable items, giving people an ominous feeling.

The dim light illuminated the pirates in the prison with fierce eyes, each grinning and looking at the group outside, their teeth grinding and making a chilling sound.

Each of them was a notorious thug on the sea, thrown into this dark place after being caught.

Under this dim light, they were like beasts trapped in the abyss.

Their respective anger and bloodlust were magnified several times in the small cage.

The arrival of Jin and the others was like a stone thrown into a stagnant pool, stirring up uneasy ripples in the depths of the prison.

Each pair of eyes was like a torch, the firelight reflecting the most primitive wildness in their lives, reflecting their endless desire for freedom and the painful anger of being imprisoned.

They stared at Barrett, who was being escorted by the marines, the ferocity in their eyes more terrifying than the prison.

They pounced on the iron bars, their veins bulging like vines wrapped around their arms, their nails scratching the iron bars, making a piercing sound that was exceptionally clear in this deathly silence.

For a time, the sound of chains and bars colliding echoed in this forbidden area of the sixth level.

"Hahahaha, there are newcomers again."

"This time, which unlucky guy came in."

"Come over and give Grandpa a good time, I guarantee you won't forget this taste."

"Magellan, I heard you became the vice warden, come over and fight me to celebrate."

"Don't embarrass him... it would be fun if he ran off to have diarrhea halfway through the fight."

"Ah hahahaha......"

Their actions and words together constituted a chaotic world.

The hostility between the pirates and the marines was like an invisible high wall, pushing them completely into opposition.

Magellan stood in the center of the road, his skin, which hadn't seen sunlight for many years, appeared pale and cold.

He gave the protagonist and his party an apologetic smile.

Such an expression appeared so rarely on his face that it seemed somewhat stiff and unnatural.

"Sorry."

"These guys are always so noisy."

Suddenly, Magellan's eyes narrowed.

He gently raised his palm.

A huge dragon-shaped object silently emerged from his palm.

It was made of Magellan's terrifying venom, the color deep and dangerous.

The dragon-shaped venom monster drew a chilling purple trajectory in the air.

Then it slammed into the prison wall, making a dull thud.

The pirates' originally provocative voices disappeared without a trace in an instant.

Their crazy agitation all turned into silence.

The light no longer flashed with ferocity, but was replaced by a bottomless fear.

"Finally a little quieter."

"They really don't learn, they can't be peaceful even when they're locked up."

Magellan said coldly, the vice warden's majesty fully embodied.

Magellan's power was undoubtedly shocking, and the eyes of the other guards in the sixth level also revealed their awe for his ability.

It was because of Magellan's terrifying strength that he was able to sit in the position of vice warden.
