Logia-type users can surely use Armament Haki, but Observation Haki should be prioritized over Armament.
Otherwise, dodging such a simple thumb flick wouldn't be so difficult.
A guy who can't use Observation Haki...
"Is nothing impressive after all!"
Just as Ace was still in shock, he sensed a shadow suddenly looming in front of him, followed by a gust of wind.
As he barely raised his eyelids, a massive fist had already reached his face.
Instinctively, he used his arm to block, but the moment the fist made contact, an immense force surged through, causing his mouth to open involuntarily and spit out a mouthful of blood.
Bam!!
The ground was deeply cratered, and Ace was slammed harshly into it. As debris flew everywhere, his entire body instantly transformed into flames, escaping the blow of the fist.
The flames quickly gathered at the other end of the crater, forming his body. His hands trembled as he bent over, breathing heavily, blood seeping from the corners of his mouth.
The strength of the Haki was terrifying, even more so than before; the speed and power were clearly on a different level now!
This guy...
Ace gritted his teeth as he fixed his gaze on the nearly monstrous armor-clad Sage, saying, "Monster!"
"You blocked it, huh..."
Sage glanced at the faintly fading Haki on Ace's arm, saying, "What about the second punch?"
Whoosh!
Sage's figure vanished again, moving at a speed almost invisible to the naked eye, creating a gust that blew Ace's hat off, the strap hanging around his neck.
Kuma!
In the instant Sage disappeared, a massive flame burst from Ace, transforming him into a spiraling column of fire shooting towards the sky. In the midst of the rising flames, the base was punctured, scattering sparks everywhere.
Sage withdrew his fist, casually extinguishing the flames on his hand, looking up above.
The spinning flames left the ground, spiraled upward, with Ace's figure floating at the center, allowing the flames to swirl around him.
"Flame Ring..."
He raised his hands high, gathering all flames into them, and fiercely struck downward, "Fire Pillar!!"
A massive spiral flame formed a column, attacking downward with a roar. For a moment, even the sky turned a fiery red.
The intense heat had long driven away nearby residents, now watching from afar with fear as the massive fire pillar appeared abruptly.
If it fell, the city could turn into a sea of flames!
"Hey, what's going on? Is that guy really that powerful?" Renedia gasped in shock.
Marika chuckled, "Well, he is a Pirate with a bounty of 550 million, a big shot on the seas, double Sage's bounty, but..."
"But he's no match for Sage."
Lily added, "At this level, he can't beat Sage."
The flames indeed roared with fierce, destructive energy, but didn't give them a sense of impending doom.
Compared to encountering Garp and Zephyr, who exuded an almost despairing pressure, this fire pillar... at least for Sage, seemed effortlessly manageable.
The fire pillar descended toward Sage like divine punishment, casting his body in red. The high heat made this desert city inexplicably catch fire around it, spreading the blaze.
"Fire, as the most primal form of destruction, indeed packs a punch, but on the seas..."
Sage looked up at the descending fire. The pillar now hovered above, its heat even twisting his white hair's tips, yet he calmly spread his arms, clapping them together.
"Haki, is what truly reigns supreme!"
Black flowing fire moved from his hands, gathering into a black sphere at the point where his hands met.
"Hadoken..."
Sage thrust his hands at the descending fire pillar. The black sphere turned into a black fiery stream as thick as an arm, colliding with the pillar.
"Heavenly Destruction!!"
Boom!!
"Wow!"
On the other side of the city, as Luffy was being pursued by the Navy, he turned back with a grin and said, "What a big firework display!"
"That's terrifying, what is that? Luffy, stop gawking; didn't you say Smoker's catching up?"
Sanji, beside him, saw the massive fire bloom in the sky, startled for a moment, then quickened his pace toward the port.
The Navy was in hot pursuit behind them.
"Over here!!"
As they were about to run out of the city, a group of Navy soldiers appeared from a side street, weapons drawn.
"Straw Hat, and Roronoa Zoro, you can't escape now!"
Tashigi followed closely with a team from another direction, forming a triangle with the Navy behind to encircle them.
They halted, instinctively surrounding Vivi at the center.
Sanji clicked his tongue, pulling out a lighter to light the cigarette in his mouth, exhaling smoke as he said, "We'll have to fight."
"Ah..."
Zoro gripped Wado Ichimonji in his mouth, then drew two swords, saying, "Chopper's still missing, we must deal with these Navy guys first."
Nami and Usopp flanked them, one with a slingshot, the other with a Weather Staff, nervously facing the Navy.
"Let's fight then!"
Luffy clapped his hands, cracking his knuckles, laughing, "I won't let you capture me!"
