One Piece: Starting with Breathing Techniques

……

A deafening roar and a dizzying shaking jolted Kiro awake from his unconsciousness.

—What happened?

The next moment, Kiro, who was in a daze, suddenly woke up, opened his eyes alertly, and rolled off the ground.

Wait, am I fighting the Demon King, Muzan Kibutsuji?!

Why did he fall into a coma?!

Muzan Kibutsuji, the nightmare that haunts the hearts of all Demon Slayer Corps swordsmen, the progenitor of all demons.

Today is the day of the decisive battle between the Demon Slayer Corps and Muzan Kibutsuji, and Kiro, who has mastered all the breathing techniques and is known as the strongest pillar of the Demon Slayer Corps in nearly a century, is undoubtedly the core force in the fight against Muzan Kibutsuji.

But he himself had fallen into a coma?!

There's no time to investigate the cause of the coma; the most urgent task is to support the various Pillars of the Demon Slayer Corps!

Kiro instinctively reached for the hilt of his sword at his waist with his right hand, but then abruptly stopped in mid-air.

The last image in my memory suddenly flashed into my mind.

Wielding his blazing Nichirin Blade, he personally shattered all five brains and seven hearts of Muzan Kibutsuji before cleanly severing Muzan's neck.

Does that mean Muzan was already killed by himself?

Oh right, Kiro remembered!

The entire Demon Slayer Corps activated their Demon Slayer Marks and fought a fierce battle against Muzan and his demon horde for an entire night.

As the strongest pillar, Kiro paid the price of burning his life potential, finally holding out until sunrise and completely destroying Muzan.

After he unleashed the sword that completely severed Muzan's life, he felt a warm current, then his vision went black and he fell into a coma.

So now it's...?

Kiro suddenly frowned. Ever since he mastered the Breath of the Sun, he had never felt weak.

But now...

He belatedly looked at himself and realized that his arms, which he remembered as having well-defined muscles, had become thin and weak, clearly the shape of a child's arms!

Just as Kilo was puzzled, a sudden burst of intense artillery fire interrupted his thoughts.

He looked around and realized that he was on a large sailing ship, with the decks crowded with civilians carrying packages of all sizes.

They looked on in fear and unease at the island behind the ship.

Kilo followed the crowd's gaze toward the island, but when he saw the details, his pupils suddenly contracted.

A towering, dense forest surrounds a massive tree whose canopy almost completely covers the island. Scattered buildings and numerous shops line the streets, all signs indicating that people live on the island.

But right now...

The island's tranquility was abruptly shattered by a barrage of heavy artillery fire.

Ancient, towering trees collapsed under the roar of shelling, and buildings full of life were reduced to ruins by successive shelling attacks.

Kilo's face had just shown surprise and shock, but his expression suddenly froze in the next instant.

He saw several civilians fleeing in panic from their homes, only to be engulfed by relentless artillery fire the next second, their bodies pulverized in the smoke and dust kicked up by the explosions.

As the line of sight extends, such tragedies are unfolding on this island that is constantly being shelled.

Reflected in his black pupils was the horrific bombardment on the island. Kilo looked sharply toward the source of the shelling and saw rows of pale blue warships flying flags bearing the word "Justice," relentlessly unleashing their firepower upon the island.

Seeing the familiar warships and then catching a glimpse of the towering trees slowly collapsing under the gunfire, Kilo's heart skipped a beat.

The Tree of Omniscience?!

He quickly grabbed a newspaper that was casually placed on the side of the deck and found the answer he was looking for in the upper left corner of the newspaper.

"Haiyuan Calendar, 1500".

Haiyuan Calendar?!

Could it be... that I've time-traveled again?!

Having traveled from the world of Demon Slayer to the world of One Piece once again?!

Kiro's forehead creased with disbelief. He had never heard of such a thing before, yet he never expected it to happen to him.

But there's clearly no time for him to think further, because right now, a much bigger crisis awaits him.

He remembered this scene: the infamous Ohara incident in pirate history!

Moreover, it now appears that the negotiations between the scholars of Ohara and the Five Elders have broken down, and the final stage of the Navy's complete annihilation of Ohara has arrived!

Suddenly, the deck shook, and the sailboat beneath their feet, filled with fleeing civilians, began to drift away from Ohara, which was being bombarded by artillery fire.

Kiro's face gradually darkened.

Isn't that the refugee ship right now, the one that Akainu ordered to be sunk?!

A chill ran down Kilo's spine; he realized he had to do something! If he stayed on this refugee ship, death was the only thing waiting for him!

But his current physical body is so weak. If he had the physique of the Demon Slayer world, he was confident that he could escape from this disaster.

But now this body, which is probably only eleven or twelve years old and hasn't been exercised yet...

Feeling the weakness coursing through his body, Kiro gritted his teeth.

How come we just finished fighting Muzan, and now we're facing an even more difficult hellish start?!

What to do?!

With no way out, Kilo leaped through the crowded refugees, glancing at the bewildered refugees out of the corner of his eye, and let out a barely perceptible sigh.

I'm afraid I can't even take care of myself right now, let alone save these unarmed refugees.

"Hey kid! The ship's already set sail. If you get off now, you won't be able to get back on!"

Ignoring the astonished looks of the crowd, Kilo jumped off the refugee boat and quickly swam to a beach in Ohara.

Ohara was now in chaos, with artillery fire and soldiers everywhere.

A dozen or so naval squads armed with smoothbore muskets were wreaking havoc in the village, while the entrance to the Ohara Library in the distance was piled high with the corpses of numerous archaeologists.

Despite the discomfort in his lungs from running at high speed, Kilo kept his head down and ran, narrowly avoiding a group of searching naval personnel, while his mind raced to find a way out of the predicament.

What should I do?

Kilo was unwilling to die on this island so soon after his arrival.

He silently called upon the cheat code, and that familiar, cold voice rang out.

[Proficiency panel is being upgraded]

"Why now of all times!"

Kiro's eyebrow twitched suddenly.

He vaguely remembered that the warm current after killing Muzan seemed to flow into the cheat system panel.

Perhaps it's related to the panel upgrade?

It seemed the panel was out of the question. Kilo gritted his teeth and rushed out onto the beach.

Before they had gone far, a loud bang came from behind. When they turned around, the refugee boat they had been on was slowly sinking into the sea under the cover of gunfire.

Damn!

He narrowly escaped death!

Turning around, Kilo continued his escape, glancing at a warship out of the corner of his eye and seeing a crimson figure draped in a cloak standing on its bow.

He was taken aback, then a chilling killing intent flashed in his eyes.

Akainu!!!

In the original story, it was Akainu who ordered the refugee ship he was on to be sunk!

Keeping the fact that Akainu had almost killed him to himself in his heart, Kiro began to observe the Marines searching for the survivors.

At this time, the navy searching the island was operating in small teams, each consisting of five people and led by a naval officer.

At present, Kiro is physically weak and does not have a suitable weapon. Under these circumstances, it is obviously unwise to confront them head-on. He should avoid these armed soldiers.

However, as Kilo ventured into remote areas, he found himself surrounded by naval forces searching for survivors.

With such a high level of manhunt, hiding is virtually impossible.

A few drops of cold sweat trickled down Kiro's forehead.

Am I going to die here?

Is there any other way to escape from here?

Escape from here...

Recalling the details of the destruction of Riohara in the original story, Kiro's eyes suddenly widened.

An idea suddenly popped into his mind.

If he could follow the escape route created by Aokiji for Robin, he might be able to escape from the sinking Ohara like Robin in the original story!

Kiro strained his eyes to look into the distance and, sure enough, found the giant general Saul, who had been frozen by Aokiji in the original story, on the distant beach.

it is good! ! !

Kiro was overjoyed. As long as he followed this route and found the icy path, he still had a chance to survive!

Just as Kiro was about to head in the direction of the giant, he suddenly felt a pricking sensation in his chest.

Kilo's pupils constricted, and almost without thinking, he lunged forward.

呲!

A spray of blood splattered, and Kiro immediately felt a sharp pain in his left arm.

Instead of checking his wound immediately, he turned and stood up with a grim expression.

As he looked up, several figures dressed in white military uniforms and carrying knives came into his view.

The leader was holding a smoothbore gun, from which smoke slowly rose.

"Captain Aitch, how could that shot miss?!"

"Your accuracy needs improvement, hahaha!"

The men's conspicuous white military uniforms were printed with a seagull holding a scale in its beak.

It was an entire naval squad searching for survivors!

The naval squad in front of him had clearly set their sights on him.

Kilo's heart sank to the bottom.

The thing he least wanted to see still happened.
