Chapter 43: The Strike to Kill a Dragon

The stars stretched endlessly above me as I stood alone on the deserted island, my sword resting in my hands.

I had spent seven years training, fighting, and growing stronger—but I was not yet ready.

Kaido was a monster. An undefeatable force of nature.

His near-immortal body, his indestructible dragon scales, and his unmatched endurance made him the strongest creature alive.

If I was going to defeat him, I couldn't just be strong. I had to be unstoppable.

I needed one attack.

One that would tear through his defenses.

One that would cut through even his dragon form.

One that would kill him where he stood.

The Core of My Power

I had gathered my abilities carefully over the years.

✅ Supreme Swordsmanship – My blade had reached the pinnacle, a black blade that could cut anything.

✅ Supreme Conqueror's Haki – My will had become as dominant as Whitebeard's and Shanks'.

✅ Advanced Armament Haki – My strikes could bypass durability and destroy from within.

✅ Supreme Observation Haki – I could see into the future, predict movements, and feel the smallest shifts in energy.

But alone, these abilities weren't enough.

Kaido had all of them too.

I needed to combine them.

I closed my eyes, breathing deeply.

The perfect attack needed four things:

1️⃣ Unmatched Haki Infusion – To bypass Kaido's dragon durability.

2️⃣ A Black Blade's Cutting Power – To ensure the strike left a fatal wound.

3️⃣ Perfect Execution – A single clean strike with no wasted movement.

4️⃣ Speed Beyond Perception – So that Kaido couldn't dodge or counter.

I had to merge all my power into one singular, absolute strike.

Training Begins – The Fusion of Power

For the next several days, I dedicated myself to perfecting this attack.

At first, I tried simply infusing my Supreme Conqueror's Haki into my sword.

When I swung—the very air cracked apart.

But it wasn't enough.

Kaido wouldn't fall from a simple slash.

I needed more.

So, I concentrated my Advanced Armament Haki, compressing its power into a single point.

My first test strike shattered a mountain.

But even that wasn't enough.

Kaido could tank island-level attacks.

I needed something deadlier.

I moved onto the next step—Observation Haki.

I had always relied on future sight, but for this attack, I needed more than that.

I needed absolute certainty.

I closed my eyes, sinking into a deeper level of mantra, extending my senses.

I let my blade become an extension of myself.

The world slowed.

The air whispered as I swung.

For the first time, I could see the precise moment my blade would land before I even moved.

I was close.

But there was one final step.

Creating the Ultimate Strike

The last step was the hardest.

I had to bring everything together—my Black Blade, Supreme Conqueror's Haki, Advanced Armament, and Supreme Observation.

This wasn't just a technique.

This was my final move.

I raised my sword and took my stance.

The wind stilled.

The island went silent.

I exhaled—calm, focused, absolute.

Then—I struck.

For a moment—nothing happened.

Then—the entire island trembled.

A massive, pitch-black slash erupted from my blade, tearing the sky in half, splitting the ocean apart for miles.

Everything before me was obliterated.

I had done it.

I had created an attack capable of killing a dragon.

The Name of the Attack

I stood amidst the devastation, my blade humming with power.

I clenched my fist.

This wasn't just an attack.

This was the blade that would end Kaido.

I closed my eyes, feeling the weight of the name forming in my mind.

"Ryūketsu Tenka" (Dragon-Blooded Heaven).

The sword strike that would slay a dragon.

The technique that would liberate Wano.

The moment Kaido stood before me, it would be his end.

I turned to face the horizon.

The time was coming.

Soon, the dragon would fall.
