Looking at the increasingly familiar yellow hair, childhood memories flashed through Luffy's mind.
"Cough, cough!"
Sabo coughed out fresh blood, enduring the dizziness in his head as he struggled to get up.
The reason he could still get up was, of course, because Renji hadn't used much strength. Otherwise, such a moving scene wouldn't be visible now.
"Sabo!"
Luffy looked at Sabo in surprise. Even after many years, he still recognized his brother at a glance.
"Ugh!"
Sabo shook his head and looked at the rubber man in front of him. "Luffy?"
Sabo's expression gradually turned to surprise, and then, at that moment, a hand suddenly pressed down on Luffy's head.
Buzz!
The milky white vibration force, mixed with Blue, then pressed Luffy's head violently down onto the deck.
Terrifying power poured out wildly. Luffy felt something pressing on his head, and before he could even resist, his vision began to spin, and immense power came from his head, almost causing him to fall into unconsciousness.
"Luffy!"
"Luffy-senpai!"
The Straw Hat Pirates screamed in horror, and Bartolomeo clutched his head with a panicked expression.
Boom! Crackle!
As Luffy's head smashed into the deck, terrifying power erupted. In the face of this vibrational gravity, the sturdy deck deformed and fractured at light speed like plastic.
Room: Slaughterhouse!
At the critical moment, Law activated his Devil Fruit ability, transferring everyone except Luffy to a distant location.
He had originally thought of throwing Renji into the sea, but as expected, the intensity of the Haki wrapped around Renji's body prevented his Devil Fruit ability from working at all.
Boom!
The deck exploded, and the entire ship was torn apart by Renji's attack. Fortunately, with Bartolomeo's ability, everyone was able to stand safely on the floating debris of the wrecked ship.
A blue ball of Cursed Energy suspended Luffy in mid-air. Covered in blood, he was almost unconscious, letting out a low growl, "Ugh!"
"Luffy-senpai!" Bartolomeo looked worried.
Sabo also looked at Luffy in mid-air. His brother, whom he hadn't seen in years, was unexpectedly reunited in such a scene.
Sabo kept thinking of ways to escape, but being in the middle of the boundless sea, all his plans were rejected one by one.
"Luffy, damn it!"
Nami and the others faced this scene with fear and helplessness written on their faces.
Even Zoro and Sanji, who were usually confident, felt a sense of powerlessness from the bottom of their hearts when facing Renji.
There was no other way, the gap was simply too huge.
"This is his strength. He knocked Straw Hat into this state with one blow?" Law gritted his teeth.
Although he had heard of Renji's power before, he hadn't expected that even Luffy, whom he considered to be on par with him in strength, was no match for this man in a single exchange.
"He should at least be able to exchange a couple of blows, right?" He exclaimed in surprise.
For a moment, Law, who was skilled at utilizing the environment in combat, didn't know how to respond.
The absolute power Renji displayed was too strong, strong enough to be suffocating.
"Relax, dizziness is normal." Renji smiled, his tone light and casual, as he slowly clenched his hand.
As his hand moved, under everyone's extremely tense gaze, the rubber man that Luffy had transformed into was slowly tightened by the blue light. Under the compression of terrifying power, even Fourth Gear Luffy's body, enhanced by Armament Haki and perfectly combined with rubber elasticity, could not resist.
A large amount of white steam spewed from Luffy's mouth, accompanied by blood, as he was engulfed by the blue light.
"Damn it, Luffy! Wait for me, I'm coming to save you right away!"
Sabo looked at Luffy's pained expression, and couldn't help but recall the agonizing pain he felt two years ago, after the Marineford War, when he saw Ace's death in the newspaper. He never wanted to experience the feeling of losing a brother again.
Dragon Claw Fist: Dragon's Breath!
A very powerful Armament Haki erupted from Sabo's body, stirring up violent winds that created massive waves on the sea, like a giant dragon sucking water, forming a colossal sea tornado in less than a second.
"Roar!"
Within the giant waves, the angry roar of a dragon seemed to faintly emerge, making the eardrums of the surrounding people tremble.
"This guy... the scar on his face. No mistake, it's the Revolutionary Army's number two, Chief of Staff Sabo."
Law was the first to recognize Sabo's true identity. While surprised by this Haki, his lightning-fast thoughts led him to a way to break the current situation.
"Sabo! I'll use my ability later, and we'll save Straw Hat together."
Sabo glanced at Law. Being quite knowledgeable about maritime forces, he knew the latter's identity and abilities.
The Surgeon of Death, an Ope-Ope no Mi user. With his cooperation, the chances of rescuing Luffy from that guy's hands would greatly increase.
"I know!"
With a low shout, Sabo's temple veins bulged. His gloves couldn't withstand the incredibly destructive Armament Haki surging wildly from his body.
Renji's lips curved into a smile.
At this moment, Sabo's strength as the Revolutionary Army's number two was fully displayed.
Terrifying and astonishing Haki, centered on Sabo, whipped up a giant wave shaped like a dragon's head, and Sabo, as if riding a dragon, roared and blasted towards Renji.
"He's someone who can exchange blows with Fujitora after all, indeed much stronger than the current Luffy."
Facing such a horrifying attack, Renji's smile remained unchanged. He even leisurely commented.
"What astonishing Haki. Is that Armament Haki? And it can be used like this."
Zoro looked at the powerful Dragon's Breath, which had many similarities to his Three-Sword Style: Black Rope Dragon Twister, though in terms of power, Sabo's Dragon's Breath was clearly more terrifying.
"Renji, let go of my brother!"
