One Piece: I will become stronger by checking in

"It feels so good to be free of Seastone!" Usopp said, flexing his wrists. The others nodded in agreement.

For Devil Fruit users, being restrained by Seastone was incredibly uncomfortable. Now that they were free, they could finally breathe easy.

"Alright, let's go rescue Luffy and the others and turn this place upside down!" Kai said calmly.

If the World Government and Marines wanted to make a big deal out of capturing them, Kai didn't mind giving them a real reason to regret it.

He turned to the four of them and said, "You guys stay here and start releasing the prisoners. I'll head down to Level 6 to rescue Luffy and the others."

"Got it!" they replied in unison.

"Then let's get started. First, I'll deal with the big shots here."

With that, Kai easily shattered the Seastone bars of the cell and stepped out. As he did, a clone appeared beside him. He planned to tear this place apart to make their escape easier.

Kai's eyes narrowed, and his aura began to surge. The sudden burst of power caught the attention of the nearby prisoners, who rushed to their cell doors, their faces lighting up with hope.

"Hey, kid! Let me out, or I'll rip your head off when I get free!" one pirate threatened.

"Yeah, let us out, and I'll let you join my crew!" another offered.

The prisoners were a mix of threats and bribes, all desperate to be freed.

"You're... annoying," Kai said coldly.

The moment he spoke, an overwhelming wave of Conqueror's Haki erupted from his body, crushing the prisoners under its weight. The weaker ones fainted instantly, while the stronger ones struggled to breathe.

"This... this is Conqueror's Haki! And at this level?!" one pirate gasped, his voice trembling with fear.

The prisoners here weren't weaklings. They knew exactly what they were dealing with. But they'd never seen Conqueror's Haki this powerful before.

In an instant, their attitudes shifted. Fear and respect replaced their earlier bravado. The pirate who had been shouting the loudest earlier was now cowering in the corner, trying to make himself as small as possible.

After a moment, one pirate spoke up, his tone completely different from before. "Uh, sir... could you let us out? I don't mean any harm. I just want to help you. You know, distract the guards or something."

The other prisoners stared at him in shock. Since when had this guy become so... polite?

Kai found it amusing. The sudden shift in attitude reminded him of the "face-changing" performances from his past life.

"Step back," Kai said, raising his staff.

With a single swing, he shattered the cell bars, creating a hole large enough for the pirate to escape. The man didn't hesitate, rushing out the moment the path was clear.

The moment he stepped out, he took a deep breath, savoring the taste of freedom. Even though he was still in Impel Down, being out of that cell felt like a miracle.

The other prisoners watched with envy, their earlier pride forgotten. They began showering Kai with compliments, desperate for their own chance at freedom.

But Kai ignored them. He didn't have time to free everyone one by one. Nami and the others would handle that. He'd only freed this one because the guy's sudden change of attitude had amused him.

Now, it was time to get serious.

Kai looked up at the ceiling, his clone doing the same. Both gripped their staffs tightly, their auras rising to terrifying levels.

The prisoners fell silent, sensing something monumental was about to happen. They could feel the energy building, and it filled them with both awe and dread.

Then, with a sudden burst of power, both Kai and his clone swung their staffs upward.

"Haki Burst!"

A massive wave of energy shot upward, tearing through the ceiling like it was paper. Black and red lightning crackled around the attack, and the entire floor shook violently.

The prisoners watched in stunned silence as the attack blasted through layer after layer of Impel Down, shattering everything in its path. The sheer force of it made the entire prison tremble.

On Level 4, Warden Magellan felt the violent shaking and rushed out of his office. What he saw made his heart skip a beat.

A crimson energy wave was rising from below, tearing through the ceilings of Impel Down like they were nothing. The sheer power of it made even Magellan, a man who had seen it all, feel a deep sense of dread.

"This... this is bad," Magellan muttered, before sprinting toward the source of the attack.

Meanwhile, on Level 1, Buggy was lounging around, waiting for the commotion Kai had promised. He was feeling pretty good, half-free and dreaming about life after prison.

Then the ground shook violently. Buggy looked down, confused. The vibrations were coming from below.

"Boom!"

Before he could process what was happening, the floor in front of him exploded, and a massive energy wave shot upward. When the dust settled, Buggy walked over to the edge of the hole and looked up.

His eyes widened in shock.

He could see the sky.

Impel Down...

Had been pierced.
