One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

Im's longsword slashed diagonally upwards and then downwards, with jet-black flames spreading along the blade, attempting to burn through Roy's Armament Haki.

Roy flicked his wrist, channeling his telekinesis into the blade, blocking the longsword while simultaneously repelling the black flames.

He used the momentum to deflect the force, then slashed back with his sword, aiming for Im's throat.

Im tilted his head to avoid it, the blade grazing his neck and sending sparks flying.

"Damn it!"

Roy cursed under his breath.

In this form, Im's defense is even more monstrous than he imagined. If that knife had landed, an ordinary opponent's neck would have been broken long ago.

"Your knife isn't sharp enough."

Im tilted his head, his arms suddenly bulged, and the black knife pressed down again, the blade slicing through the air, a terrifying wind pressure raging, slashing down on him.

"clang--!"

A sharp sound of swords clashing rang out. Roy raised his sword to block, but was forced to plummet from mid-air.

Roy shook his numb arm, and blood seeped from the web of his hand where he gripped the knife.

After enduring this attack, the Black Blade Autumn Water, which had been around for eight hundred years, developed a noticeable notch on its blade.

Roy's mind raced, and he stopped his falling body.

His eyes were fixed on Im, who was swooping down.

"Sizzle!"

Roy dodged to the side, but Im's blade still grazed his left arm, leaving a charred tear in his clothes.

Using the force, Roy flipped over and kicked Im in the back, sending both of them flying in opposite directions.

The two turned around simultaneously in mid-air and rushed towards each other at the same time.

Black Blade and Autumn Water clashed once again.

This time, the standoff lasted for three seconds.

Black flames and indigo-colored psychic energy clashed wildly at the blade's edge, forming a rapidly spinning energy ball.

The energy ball grew larger and more unstable until it finally exploded with a bang.

Roy and Im were both thrown back by the shockwave.

Roy was sent flying dozens of meters away, and he had to stomp his feet several times in mid-air to regain his balance.

Im spread his wings and took to the air once more, unleashing another burst of Conqueror's Haki, his entire body enveloped in a mixture of black flames and Conqueror's Haki.

Like a black meteor shot from hell, the blade aimed straight for Roy's throat.

The sonic boom generated by the Blackwing's vibrations could be heard clearly even on the ground.

Roy activated his telekinetic domain to its fullest extent, breaking down Im's movements into countless nodes, with the force, direction, and speed of each node clearly mapped in his mind.

His body traced a "Z" shape in the air, narrowly avoiding the fatal blow.

The black blade swept past him, its energy pressing down on the ground like a black wall, turning a patch of ruins into dust.

Im did not sheath his sword. Using the force of the swing, he turned in mid-air, his left arm sweeping out, and five blade-like fingers plunged into Roy's abdomen.

Roy instantly formed a barrier around his abdomen with his telekinesis and retreated rapidly backward.

Im's fingers brushed against the psychic barrier, making a screeching sound that sent chills down one's spine, like chalk scraping hard on a blackboard.

Im's knee came crashing down, and Roy could only block it by holding Qiushui in front of him.

"clang--!"

Roy was knocked back dozens of meters, his feet leaving two trails of air in the void.

My wrist felt slightly numb, and my eyes trembled slightly in my palm.

Im followed closely, flapping his black wings to close the distance once more. The slashes unleashed by his black blade were no longer simple blade energy, but a torrent of mixed black flames and domineering color, like a black waterfall cascading down from the sky.

Roy didn't take the hit head-on; instead, he used his telekinesis to pull him to the side while simultaneously counterattacking with his sword.

A surge of blue light erupted from Qiu Shui's blade as his psychic power and sword energy merged, forming a thin silver line that sliced ​​towards Im's ribs.

Im dodged to the side, the line grazing his ribs and slicing off several of his scales.

He glanced down and his brow furrowed very slightly.

Black flames surged up the wound, and it healed in an instant.

The two engaged in a high-speed battle high in the sky, moving so fast that those below could only see two blurry shadows colliding repeatedly between the dark clouds.

Each collision generated a huge shockwave, sending countless water columns flying onto the surface of the sea, as if something deep beneath the sea was desperately trying to push upwards.

The water column exploded, only to be shattered into mist by the next shockwave, making the entire sea surface appear as if shrouded in a white veil.

Roy's telekinetic perception was suppressed to its limit.

Im's blade grew faster and faster, its angles more and more unpredictable. More importantly, a thin layer of Conqueror's Haki mixed with black flames formed a protective barrier around his body.

Like an invisible suit of armor, every time Roy tried to use his telekinesis to invade his body, he was repelled.

"Psychological attack?"

Im's voice was tinged with contempt.

"To use such despicable means against this god is overestimating your own abilities."

Roy didn't say anything. Since direct control wasn't working, he would try to take control of the situation.

With a slight thought, the temperature in the space around the two began to drop sharply, and the air began to rotate under the pull of their mental power, forming a huge turbulent zone.

At the same time, chaotic gravitational turbulence filled the entire space.

Under the combined influence, Im's black flames were scattered by the airflow, and the black mist was blown into thin ribbons that hung in the air like rags.

Im's movements were indeed affected.

He frowned, his black wings flapped suddenly, forcibly stabilizing his body, and then he charged towards Roy against the turbulent current.

Roy no longer confronted him head-on, using his telekinesis to dart left and right like a piece of paper being blown by the wind, causing Im's attacks to miss repeatedly.

"You're like a fly." Im's voice was as cold as ice.

Roy ignored it, continuing to increase his telekinetic output, making the surrounding air increasingly thinner.

Roy drained the oxygen from the space in a very short time.

Im's breathing became heavy and slowed down slightly.

"Have you had enough fun?!"

Im roared, and black flames surged, burning away the surrounding turbulence and poisonous gas. His figure descended like a demon god amidst the flames, slashing at Roy with a single blade.

A strange light flashed in Roy's eyes.

He hadn't expected this move to kill his opponent, but Im's reaction was faster than he anticipated.

This body's tolerance to the environment is far greater than that of a normal person.

There is no room for wishful thinking.

Roy parried with his sword.

Blue light and black flames exploded where the blades clashed, the blinding light causing those on the ground to close their eyes.

After the light faded, the two were sent flying backwards.

Roy tumbled twice in the air before regaining his balance, a trickle of blood spilling from the corner of his mouth. His clothes were burned through by the black flames, revealing slightly reddened skin underneath.

Im was also in bad shape, with a shallow wound on his chest that glowed with blue light. The knife mark stretched from his right shoulder to his left abdomen. Although it was not deep, the blue light clung to the wound, preventing the black flames from healing quickly.

The air currents in the high altitude dispersed, causing the hems of their clothes to flutter loudly.

Roy raised his hand, wiped the blood from the corner of his mouth with his thumb, glanced down, and then smiled.

"Not bad." He looked up at Im. "That's more like it."

Im gripped the black blade tightly, black flames churning on its surface, his black, swirling eyes devoid of any warmth.

"How long are you going to keep playing this game? I've already seen through your tricks."

Roy's smile remained unchanged: "You've seen through it all? Are you sure?"
