A Killing Blow Through Observation! Fierce Battle! Victory!

Roger's chest heaved, and the Haki surrounding him dissipated. Even so, numerous burn marks remained on his body, the most severe being his left forearm, which was completely blackened and almost carbonized.

The man known as the Pirate King was utterly shocked!

That's incredibly powerful!

Even though he swung his knife to deflect the flash of light from the explosion at the first moment, he still suffered considerable injuries.

The Calamity Roa truly lives up to its name!

Every gesture they make is a true catastrophe that can destroy the world!

A single blow could shatter an island! Even Whitebeard couldn't achieve that level of destructive power, right? Golden Lion should be able to, provided he has another island to bombard.

The destructive power displayed in that encounter three years ago was already exaggerated enough, but now it seems that it was just the fledgling eagle's first cry? Now his destructive power is truly being revealed!

No, I can't engage him in a long-range firefight; I have no chance of winning that way!

Roger bent his knees slightly, and in the next instant, he exerted force with his leg muscles. Because of the explosion, the rock layer above had disappeared into thin air, and the exposed bedrock shattered. He shot into the sky at an angle like a cannonball, heading straight for Roa in the sky.

The instant he jumped, boom! A terrifying tsunami converged from all directions, the immeasurable weight of the seawater crashing together, instantly creating giant waves hundreds of meters high!

"Roa!!"

The air was pierced, and Roger's body stretched into a black line out of thin air, surrounded by rings of sonic boom clouds.

"Hahaha! Come on!"

Roa laughed heartily and flapped its wings to meet the attack.

That's ridiculously Haki! Meeting the explosion at such close range, and only getting this little injury?

Hmm, but thinking about it carefully, it doesn't seem so strange.

In the movie, that old Zephyr also experienced a massive explosion at close range, enough to destroy an island, but he was completely unharmed. After being unconscious for a while, he was quickly revived by Chopper.

The bomb that Crocodile of Alabasta could blow up a city couldn't even kill a Haki idiot.

The power of an explosion is just for fun; to really kill someone, you need real guns and knives.

But that's exactly what's good!

Roa laughed wildly, his Tiger Soul wreathed in various elements, which accompanied his rapid advance, leaving a long, rainbow-like trail of flame.

Come on, Roger, let's make this last battle of our lives a grand and inspiring one!

The two collided again in the next instant.

The surrounding air was almost instantly cleared away, and the surging, domineering Haki blasted everything around them away, turning the area around the two into a vacuum.

Below, the towering waves were immediately struck head-on, instantly creating a huge crater hundreds of meters wide.

The almost evenly matched strength allowed the two to send each other flying again, leaving two black streaks in the air.

"Haha! I knew the explosion couldn't have had no effect!"

Roa Ya laughed heartily, and a meteorite with a diameter of over fifty meters suddenly materialized behind him. He landed perfectly on the meteorite, and as he exerted force with his legs, his wings flapped, instantly propelling him to his maximum speed.

Roger! Your strength is weakening!

On the other side, Roger, who had also been knocked away, plummeted diagonally towards the sea below.

He glanced down at his dark left hand.

Not only his skin, but his muscles were also severely damaged, and the strength in his left hand was significantly weakened.

But thankfully, physical strength is secondary; Haki is the key!

Roger crashed into the sea.

Winner Island had been blasted to pieces by the explosion, and there was no longer a place for Roger to land on this vast sea.

But the next instant, the sea, which had been churning from Roger's crash, exploded again.

Roger leaped out of the sea, and like a gust of wind, he sped forward across the surface of the water!

"Wow! We're wading through the water!"

Roa, falling like a meteorite, laughed in surprise, "You've got a mix-up, haven't you?"

However, since Geppo allows one to walk on air, why can't it do the same on water?

Am I trapping myself in this situation?

Thinking this, Roa's smile grew even more unrestrained, "Tiger Devour!"

He gripped the knife with both hands and chopped downwards with all his might.

A gigantic tiger, composed of various elements, materialized out of thin air. No longer just a single head like it had been when fighting Kaido, it now possessed all its limbs and roared as it lunged to tear at Roger.

"Wild Spirit!"

The powerful black and red slash instantly tore through the sky and struck the tiger's head. The two astonishing forces collided violently, Air Shock and causing the sea to boil.

"Roar!"

The tiger roared angrily, but it was powerless against the massive slash.

Just then, a foot suddenly stepped on its head, and then used the force to propel it up again.

"Tiger Roar!"

Roa gripped the knife with both hands and thrust it at Roger, who was launching himself forward.

The various elements emanating from the blade and the surging dark red airflow spread out, forming a gigantic tiger's head.

The tiger roared, and a massive beam of mixed light suddenly hurtled towards Roger.

Luo's moves have all been evolved once!

However, this seems to have nothing to do with swordsmanship anymore, right?

Well, who cares? Anyway, it's a sword, so it's swordsmanship.

Swordsmanship is not such an inconvenient thing.

Roger suddenly deflected the attack in mid-air, effortlessly avoiding it while simultaneously closing in on Roa again.

The combined beam of light crashed into the sea, silently piercing a bottomless hole in the turbulent surface.

Hey!

Roa sneered, wielding the Tiger Soul in his hand. The enormous pillar of light danced like a blade that reached the heavens and the earth, slashing down at Roger once more.

Damn it, the Golden Wheel Reincarnation Explosion!

Roger's eyes gleamed red; the future was already captured in his gaze at that moment.

On the blade of his beloved sword, Ace, jet-black Inazuma burst forth, instantly spreading across the sky like a spiderweb!

"Drink!"

The enormous lightsaber collided abruptly with the tiny, toothpick-like black blade before it.

The enormous beam of light, formed by the convergence of various elements, was cleaved in two by the pitch-black blade in that instant!

But Roger also felt a tremendous tremor in both arms.

Does this kid have no stamina limit? How can he keep using moves of this level?

"Ha!"

Roger swung his sword with all his might, his roaring strikes tearing the pillar of light apart.

Roa casually sidestepped, dodging the incoming Flying Slash.

However, Roger, whose attack was coming right after him, could no longer dodge it.

Then let's not avoid it!

Should I then avoid his sharp edge?

Roa laughed and swung his sword to meet the attack.

However, Roger, who had seen the future, suddenly slapped the air in front of him with his left hand, and with a muffled thud, his body abruptly stopped.

As Roa's blade passed him, Roger suddenly sprang into action again, slashing his sword towards Roa's neck.

It's so unfair that one person can see into the future while the other can't!

Roa instinctively pulled back, but even so, the incredibly tough hair on his chest was torn apart by the blade, leaving a deep gash.

"Ouch! It's been so long since anyone chopped me!"

"It's been a long time since I've been injured," Roa roared in pain.

He actually let out a roar.

The violent sound waves were mixed with dark red air currents, containing all sorts of elements.

The distance was too close; even with a glimpse into the future, Roger had no time to dodge and could only instinctively swing his sword to parry.

Then, he was blasted away by Roa's verbal attack.

Before Roger could even regain his footing in the sky, Roa was already flying in, accompanied by a whirlwind.

"It seems you're quite eager to test your swordsmanship against me, Roger. Well then, I'll grant your wish!"

Roa swung his sword down.

Roger lunged forward by stepping on the air, simultaneously swinging his sword to meet the attack.

Regardless of what Roa was thinking, this was an opportunity!

Boom!

Boom!

Boom!

The two began to collide repeatedly on the surface of the sea.

It should be said that Roger, who was able to foresee the future, had a considerable advantage.

Roa's body was soon covered with wounds.

Even with Roa's indestructible body at this moment, he was still unable to withstand Roger's strike of this magnitude.

But.

"Is the injury gradually healing?"

Roger's pupils dilated.

The wounds that were not deep to begin with, which were painstakingly inflicted on Roa, were healing at a speed visible to the naked eye!

By now, the initial wounds have completely healed!

What exactly happened?

Roger, who had never witnessed this ability of Roa before, was greatly shocked.

His overwhelming Haki, swordsmanship that was in no way inferior to his own, strength that even the Ancient Giant Tribe could not match, and various destructive moves that resembled natural disasters—and that wasn't all; he also possessed such an unreasonable regenerative ability?

Isn't that a bit too shameless? Roa, you bastard!

Being able to see the future is not invincible; Roa's speed and reaction ability are both very fast, and they were never able to inflict a fatal injury on him.

I had hoped to defeat him by accumulating injuries, but now it seems that's absolutely impossible!

"This is already considered slow!"

Roa laughed heartily.

The black energy between heaven and earth is still too thin, and the recovery of injuries and physical strength is still too slow.

So, this world needs to become even more delicious!

The road ahead is long and arduous, but we must persevere!

Hahahaha!

Roa's laughter was almost maniacal. "Keep going! Roger, I can feel it! The 'Observation Haki Killer' technique is only one step away from completion!"

So, they wanted me to be their sparring partner?

That arrogant bastard!

Since that's the case, then come on, kid!!

Roger roared and charged again.

In the sky.

"Are these really two humans fighting?"

Moria, peering down from the edge of the clouds, couldn't help but marvel, "The battle has only just begun, and that island has already been completely destroyed! And this level of attack still can't do anything to Roger?"

Even though he harbored deep resentment towards Roa, he had to admit that the guy's power was simply on another dimension!

And Roger, incredibly, fought against such a monster as Roa and was not at all at a disadvantage!

This is a super monster!

"That's why the Boss said this isn't a battle we should get involved in."

"Dylan sighed."

Even the strongest Bullet probably couldn't withstand Roger's serious sword strike, right?

This is what true power is!

Loki, who is usually a bit frivolous, looked rather serious at this moment.

The fight between the two men terrified him.

Who is stronger, these two monsters or Rocks?

"Just wait quietly."

Bullet crossed his arms, his expression calm. "The Boss will never lose!"

Below.

Roger's attack was swift as the wind.

Although he was in the air, his speed was by no means slow.

Is your Geppo proficiency increasing rapidly amidst the fierce battle?

But at this moment, Roa was too lazy to think too much; he was constantly trying to conceal his presence.

The principle behind the Observation Haki Killer technique is to conceal one's aura, preventing the opponent from using it to glean insights into the future.

This is an advanced technique that requires both Observation Haki and Conqueror's Haki to work simultaneously.

It's difficult.

Of all the Haki techniques that Roa knew, this move was the most difficult.

Therefore, even a genius like Roa was unable to master it for a long time.

But now, through constant clashes with Roger, and by continuously observing Roger and adjusting himself accordingly, Roa can clearly feel that he is getting closer and closer!

We're getting closer and closer to completing that move!

Meanwhile, Roger's expression grew even more grim.

Roa's presence is becoming increasingly faint! Although his presence can still be sensed, it is becoming increasingly difficult to use it as a basis for probing into the future.

This brat is getting closer and closer to his Observation Haki Killer.

If even your only advantage is no longer an advantage, then what's the point of talking about defeating him?

Roger's attacks grew increasingly fierce.

But.

"Did you notice? Roger!"

Roa's lips curled into a smile. Although he was caught off guard and had suffered another wound from Roger's attack, he didn't seem to care at all.

"But it's too late!"

Roa once again took the initiative and flapped its wings towards Roger.

The two supreme Great Grade Sword clashed fiercely once again in this sky.

Once, twice, ten times, a hundred times --

After a series of collisions, this moment came casually, without any particular significance.

As Roa tried to conceal his presence once again.

It's done.

And so, it was a quiet, uneventful success.

Roger's expression also changed.

We can't see it anymore! We can no longer see Roa's future!

"Now, let's begin the second round!"

Roa laughed wildly and slashed down with his sword.

At the same time, a sky full of lightning also struck down.

Not only that, a sudden gust of wind arose in the sky, the air instantly became turbulent, and Roger's speed plummeted.

The moment the blades clashed, the two figures separated instantly, followed by a thunderous strike that sent Roger, unable to dodge, crashing into the sea.

Roa flapped its wings and gave chase.

"Get apart!"

The sea obeyed his command and immediately split open a huge chasm on both sides.

Roger had just crashed onto the seabed, had barely gotten up when the underwater volcano beneath his feet erupted, and at the same time, a sword wrapped in various elements slashed down with a deafening roar.

Boom!

The seabed was instantly blasted into a huge crater by the violent force, and deep trenches were torn out around it.

"Haha! Roger! I've finally got my hands on you!"

Roa was overjoyed.

At the bottom of the pit below, Roger had a rather deep wound on his left shoulder.

Since Roger couldn't Future Sight, the two of them were now truly standing on the same starting line.

Roa's blade was finally able to touch Roger.

"It's not over yet!"

Roger's expression tightened, and he leaped up again.

"Then let's face this natural disaster head-on, Roger!"

The sea is boiling, thunder is falling, the wind is howling, and the volcano is erupting.

Roa began to unleash his full power, disregarding his own stamina.

The two then clashed beneath the surface of the sea.

The seabed was repeatedly eroded and caved in, eventually forming a huge underground cavity.

Until one moment, the already restless sea suddenly exploded.

Two dark shapes were launched from underwater and continued to collide in the sky.

This time, it was Roger's turn to be on the defensive!

While the natural disasters summoned by Roa were weaker and unable to cause serious damage to him, they were able to significantly hinder Roger's offense and defense.

Now, it's Roa's turn to start leaving scars on Roger!

Although Roa's aggressive attacks always gave Roger an opportunity to leave him with a wound, Roa's injuries were quick to heal.

Moreover, the knife in Roa's hand has a very peculiar characteristic.

"Whoosh--whoosh--"

Roger's breathing gradually became unusually heavy.

That knife is sucking his blood!

Every time the body is torn open, it absorbs large amounts of blood!

Is it the legendary Demonic Blade Blood Sea, one of the Supreme Grade Swords?

Moreover, those patterns on the blade—could it be that Roa forged it into Black Blade?

After absorbing its own blood, this guy's slashing power even increased!

If things continue like this, defeat is inevitable!

"Are you kidding me?!"

A violent aura surged into the sky in an instant. Roger's originally pale face was now strangely flushed. His condition, which should have been much worse than before, suddenly erupted with a speed that even surpassed his previous speed!

"Hahaha! Very good! That's more like it!"

Roa's smile widened.

It's willpower!

A powerful will began to drive the body!

In other words, it exploded in power!

It would be strange if someone like Roger were defeated so easily!

"Let's go then!"

Roa was completely unfazed; it was all about willpower, wasn't it?

It doesn't matter who you're talking about.

The two clashed again, the clash of blades shaking the entire sky and sea.

Roger's offensive became increasingly aggressive, and he began to recklessly trade blows with Roa.

Roa was naturally even less concerned; although the black energy between heaven and earth was thin, it was enough for him to recover from his injuries.

"Roa!"

Ace tore Roa's waist and abdomen apart.

"Hahaha! Roger!"

Tiger Soul pierced Roger's right shoulder.

At that moment, the blood pump started operating again.

But.

"A mere knife! Give me back my blood!"

With Roger's roar, the blood surging towards Tiger Soul actually stopped!

"Oh! Will Life Return?"

Roa Ya laughed heartily, "Incredible! To be able to exert willpower to this extent unconsciously!"

"I don't need your praise!"

Roger grabbed Roa's arm and headbutted him.

Roa met the challenge headbutt without backing down.

The two heads collided in mid-air, instantly unleashing a burst of Haki Inazuma.

"Your existence is too dangerous. Give you some more time, and maybe even Imu won't be as dangerous as you!"

Roger gritted his teeth.

"You think so too, right! Hahaha, Imu isn't a good person, but I didn't expect him to be so bad at even being a villain! So, I'll have to go and teach that big bad guy a lesson myself!"

Roa laughed loudly.

If Imu had just been a little more assertive, I wouldn't have needed to go through all this trouble.

I just lay down and happily absorbed the black energy!

It's all Imu's fault!

I will defeat you here!

Roger swung his sword down.

"You can't do that!"

With a roar, Roa unleashed a beam of sound that sent Roger flying.

However, at the same time, the Flying Slash that shot towards him also left another wound on Roa's waist.

"Come on, come on, Roger! Let's fight!"

As Roa laughed, a cloud of black mist surged toward him.

His injuries were healing at a speed visible to the naked eye.

"Roa!"

Roger pounced again.

The fighting continues.

The two were almost frenzied, completely disregarding their own bodies, and frantically attacked each other.

The incredibly sharp blade relentlessly tore through the opponent's body, but no one paid any attention.

This fierce battle lasted for more than an hour.

By the end, Roa felt as if all the blood in his body had been renewed.

Even if the physical injuries can heal, the blood that has flowed out cannot be returned; it can only be consumed by the Tiger Soul to increase the power of the strike.

But Roger's situation was even worse.

His injuries are irreparable.

His entire body was covered with countless wounds of all sizes; there was hardly a patch of undamaged flesh left.

If it weren't for her strong willpower, she would have bled to death long ago.

This was an unfair battle from the very beginning.

No matter how strong his willpower was, as his physical condition deteriorated, Roger's strength in swinging his sword grew weaker and weaker.

"It seems this is the end of it."

Roa was panting heavily.

The constant cycle of injury and recovery, which drained his physical strength and required replenishment, also left him quite mentally exhausted.

But the outcome is already decided!

"Roa!!"

Roger, almost losing his footing, stumbled and lunged at Roa. "Divine Departure!"

Even though he swung his sword with all his might, his trembling hands made it difficult to exert much power, and a long, narrow crescent-shaped blade flew over.

"Divine Departure? I don't!"

Roa gripped the hilt of the Tiger Soul Blade tightly with both hands.

"To end this battle, there's no better move than this!"

The various elements on the blade vanished instantly, even the Blood Qi disappeared into the blade, leaving only a powerful and domineering Haki swirling around it.

"Defeat me, Roger! You've already tried your best!"

Roa swung his sword.

The surging, domineering Haki transformed into a giant cannon!

The invisible, Haki cannon crushed the weak Flying Slash, smashing through the air with unstoppable force before slamming heavily into Roger's body.

"Forehead!"

His limbs twisted, his bones groaned, and Roger's mangled body flew out like a cannonball.

In the instant before his consciousness faded, a thought surfaced in his mind.

Oh, it's Rocks's move...
