Impel Down, one of the three major agencies under the World Government.

This deep-sea prison located in the Calm Belt is known as the most inescapable prison in the world.

Thousands of vicious criminals are imprisoned here, including some at the level of the Seven Warlords of the Sea, and even a few at Admiral level.

Outside the prison lies a windless, wave-free zone, and the entire facility is surrounded by many warships. Inside the prison are two wardens, second only to the Admirals, and many Jailer Beasts who lost their will after awakening.

At this moment, this so-called unbreakable prison is facing the greatest crisis in its history.

"Warden, there is a dragon flying toward us!"

In the monitoring room, several prison guards stared in shock at the screens.

"What is going on!?"

Magellan looked impatient.

The newly appointed Seven Warlords of the Sea, the Blackbeard Pirates, had come raising hell, but fortunately their bark was worse than their bite, and he subdued them with a single move.

He had just sent the Blackbeard Pirates to Level 6, Eternal Hell, so how could something else go wrong so soon?

He hoped it was like Blackbeard, which would not be too troublesome.

Magellan hurried to the screen and stared wide-eyed.

It was a green dragon hundreds of meters long, covered in azure scales, claws spread, emanating a ferocious and terrifying aura.

The Azure Dragon flew across the sky, and its target was the prison.

And on the Azure Dragon's head stood a tall young man.

Who could arrive riding a dragon?

Magellan could not help feeling confused.

As the Azure Dragon drew closer, the young man's figure became clearer.

"God Slayer, Caelan!"

Magellan finally recognized the figure, and his pupils suddenly contracted.

Although he had guarded Impel Down for many years, he kept up with information.

As the God Slayer, Caelan had been the most talked-about figure in the past six months, so of course he knew his appearance and deeds.

He had enjoyed watching him punch the three Admirals and kick the Yonko.

But with Caelan arriving outside the prison on a dragon, he could no longer remain calm.

At this critical juncture of the Battle of Marineford, this man coming to Impel Down could only mean trouble.

"Warden, what should we do?"

The guards' legs shook as they watched, and they were so frightened they could barely control themselves.

They also knew how terrifying Caelan was. Not long ago, he killed one of the Yonko in a single day.

Even if they were ordered to stop him, they could not.

"Hah." Magellan took a deep breath to steady himself, then immediately issued orders. "Sound the highest alert. Release the deputy warden to join the battle. This is Impel Down, and no one will be allowed to act recklessly."

"As for you, do not worry about him. Just keep an eye on the prisoners."

He planned to go with the strongest, Shiryu, to stop Caelan. As for these soldiers, they would be useless in combat, so it was better to have them watch the inmates.

"Yes, Warden!"

The guards all breathed a sigh of relief and looked at Magellan with gratitude.

As long as they were not forced to face that monster, they would be fine.

Soon, shrill alarms rang throughout the prison.

"Warning, the God Slayer, Caelan Alaric, is about to invade. Prepare for battle on all levels. If necessary, execute prisoners on the spot." The warning repeated three times.

The announcements immediately stirred both prisoners and guards from Level 6 into a frenzy.

On Level 1, the small-time pirates were in a panic.

Most of them did not know Caelan, but some who were captured recently knew his name.

Some were pirates sent in by Caelan back when he was a bounty hunter.

"Gin, is this that Caelan?"

Krieg asked uncertainly.

They had been knocked out by Caelan's greatsword back in the East Blue.

Since coming to Impel Down, they were not allowed to read newspapers, and they had little contact with other inmates.

Hearing this familiar name now, Krieg could not help feeling dazed.

"That should not be right. Based on the timing, he should still be developing in the first half of the Grand Line, right?"

Gin said uncertainly.

At that time, Caelan's title was still the strongest bounty hunter in the East Blue. What was this God Slayer?

Caelan should not have gone from a small-time hunter in the East Blue to someone who could make Impel Down itself tremble.

"Then it might be a coincidence. Still, people named Caelan are monsters," Krieg could not help cursing.

After all, he had been a top pirate in the East Blue and had roamed the Grand Line.

He had been one-shotted by a single sword when he returned for a meal. Who was he supposed to complain to?

…

Level 6, Eternal Hell.

"The God Slayer is here to join the fun today. How interesting."

When Blackbeard heard the news, he laughed out loud with joy.

He had great ambitions and wanted to recruit some subordinates from the prison, but he had not expected to be defeated by Magellan in one blow.

Just as he was feeling depressed, he heard this good news.

If Caelan took action, this Impel Down would not be able to stop him no matter what.

He was the man who wiped out the Beasts Pirates in a single day.

Never mind one Magellan, even three would not be enough.

Thinking of this, Blackbeard shouted to the other inmates in the cells, "Everyone, get ready. Work together to escape when the opportunity arises!"

Bullet asked in a low voice, "Newcomer, are you so sure the God Slayer can throw all of Impel Down into chaos?"

"Haha, of course," Blackbeard smiled confidently. "He is the World Government's archenemy, with a bounty of 5.5 billion. He has defeated the Admirals several times, and he recently defeated the Yonko Kaido."

"As long as he takes action, Impel Down cannot stop him. I just do not know why he came here. Is there someone he wants to rescue?"

"But none of that matters now. We just need to wait for chaos and seize the chance to escape."

Blackbeard laughed, revealing his missing front tooth.

"Oh? There is actually another powerhouse like this in the world." Bullet looked intrigued, then turned to Crocodile. "Sand Crocodile, I heard you were sent in by someone named Caelan. Is it him?"

Crocodile, who had been silent for a long time, said with some emotion, "It must be him. Back then, he was already as strong as a monster. Who would have thought he is now comparable to a Yonko?"

At that time, he had still been upset about being defeated by a rookie.

Unexpectedly, after only a few months apart, Caelan had become the man who defeated Kaido.

Did he really grow that fast?

If these people had not sworn it, he would have thought it was fake news.

"…"

After hearing the discussion, prisoners including Byrnndi World, Redfield, Catarina Devon, Sanjuan Wolf, and others all revealed a glint in their eyes and quietly gathered their strength.

"You are bold, openly discussing a jailbreak in front of me, the deputy warden." Shiryu suddenly spoke, his voice gloomy and mocking.

"You were thrown in here for too much killing, and you are still the deputy warden?" Blackbeard laughed darkly. "You might as well break out with us, become a pirate, and enjoy the thrill of killing."

"What a bold invitation." Shiryu licked the corner of his mouth and smiled. "I accept."

…

Not long after, a jailer came running with a key.

"Deputy Warden, Warden Magellan asks you to come out and help him fight Caelan."

The jailer kept his head down, sweat beading on his forehead, not daring to look at any of the prisoners.

"Put down the keys. I will be right there."

Shiryu said softly.

"But…"

The jailer hesitated, but Shiryu had already sliced off his head with a single stroke.

Shiryu picked up the key on his blade, opened his own cell, and freed the prisoners on Level 6.

"Go and release the other inmates. Create more chaos." A bloodthirsty light flashed in Shiryu's eyes. "I will go meet the God Slayer with Magellan."

Shiryu gripped the famed blade Thunderstorm and walked up to the higher levels.

Blackbeard, Bullet, Byrnndi World, and other infamous pirates walked out of their cells and began to limber up.
