The Enemy Shall All Be Cut Down, and Nothing Shall Withstand the Blade!

As a qualified and excellent father, Guilliman immediately summoned all the Ultramarines.

He chopped up Skarbrand's sausage in front of everyone and gave it to his son as a gift!

This was directly recorded by the Legion Priests in the Legion's annals, as a secret... oops, a glorious existence of the Ultramarines Legion!

First, long live the Imperium!

Second, Ultramarines have no secrets!!

Dark Angels:??? These are all my words!

In the darkness, it seemed as if some supreme gaze had frozen over it.

On the Golden Throne, the Emperor's will emanated a violent, almost trembling, energy that nearly made the Astronomican flicker. "Who the hell approved this guy to be a sword saint?!"

Don't I have any dignity?!

Warp, Brass Throne.

Khorne's incessant war cries came to an abrupt halt, as if his throat had been gripped.

Several seconds later, a muffled roar, its meaning complex and somewhere between rage, astonishment, and a strange "appreciation," was heard.

Instead, from Slaanesh's realm came a long, languid, and playful groan, as if he had seen some kind of highly "creative" and "contrastingly beautiful" work of art.

On the battlefield, the Bloodthirster was already suffering unimaginable pain and humiliation (a double blow to the Khorne Daemons).

He knelt on the ground, his body convulsing, and he was temporarily unable to fight.

Cato Sicarius stood behind it, calmly flicking the blood off his longsword, and said loudly, "Don't point your red ass at me again!"

My sword, that of Cato Sicarius, will not be pointed at such filth!

His voice suddenly rose, carrying a commanding authority. "Turn around and face me!"

Such pain should not stop you.

It is an immense honor for you to fight against the Ultimate Sword Saint!

The massive body of the Bloodthirster trembled violently, not from fear, but from an extreme ferocity that transcended anger, a desire to devour the blue bastard before it, along with the entire galaxy.

It used all its willpower to stiffly and inch by inch twist its body.

His crimson, lava-like eyes were fixed on Cato Sicarius, the hatred in his gaze almost materializing into flames.

"Roar...!!!"

It let out a deep roar like a volcano about to erupt, picked up its warhammer from the ground, and, enduring unspeakable pain, strode forward, launching its final, all-out charge!

Every step he took caused the earth to tremble; his momentum was astonishing.

Cato Sicarius, however, remained calm.

He held the sword in one hand, while gently stroking the blade with the other, his movements as elegant as polishing a precious gem.

As he stroked it, the azure Smart Atoms radiance and golden Primarch Psionic Energy on the sword surged forth as if awakened.

The flames intertwined into a dazzling blue-gold hue, enveloping the entire longsword.

"This sword was forged by my father specifically for me."

He spoke calmly, as if introducing an old friend, saying, "He said, 'You are the Sword Saint of the Ultramarines; wielding this sword, you shall vanquish all evil.'"

Therefore, I named it 'Slay'!

As he finished speaking, Cato Sicarius the longsword, which was burning with blue-gold flames, to its sheath at his waist. He leaned forward slightly, lowered his center of gravity, and placed his right hand lightly on the hilt.

An ancient, simple yet explosive stance—resembling the essence of a lost art of swordsmanship that seeks a single, fatal blow.

Iai!

Also known as Thunder Breathing First Form - Thunderclap Flash!

In ancient times, there were Japanese-style iai, American-style iai, and today there are Ultramarines Iaijutsu!!

"No enemy will escape our wrath, no enemy will be spared!"

He recited in a low voice, each word seemingly carrying a metallic tremor.

The Bloodthirster's charge was upon them, its devastating hammer crashing down with the force to smash everything into mincemeat!

The force of the hammer's blows was so intense that it made it hard to breathe.

Just as the shadow of the giant hammer was about to completely engulf Cato Sicarius —he moved.

It cannot be described as simply "fast".

That's a phenomenon.

A brilliant, pure golden thread, seemingly compressing all the light in the world into its essence, burst forth from his waist!

There was no sound, or rather, sound was left far behind this "line".

The thin golden line extended forward, effortlessly slicing through the seemingly unstoppable giant hammer.

The hammerhead split silently in two.

The thin line continued forward, touching the chest of the Bloodthirster archetype, covered in thick bone armor; touching its bones, harder than Adamantium; touching the raging, boiling energy core within it...

Everything, cut down.

Trajann stared in shock, his eyes wide.

With his dynamic vision and combat intuition Captain-General of the Adeptus Custodes, he was completely unable to see the trajectory of that sword strike!

He only saw a flash of golden light, and then... it was all over.

What pure speed that was!

What a domineering slash!

It was as if it weren't a sword, but a slash that severed reality!

Like the darkest moment before dawn in Terra, a golden horizon stubbornly rises from below the horizon, piercing the night and announcing the arrival of daylight.

Cato Sicarius's figure had already appeared behind the trajectory of the Bloodthirster, his back to the massive, stiff body.

He slowly lowered the longsword, its light fading, back to his waist, and softly uttered the name of this move:

"Golden... skyline."

With his voice...

The body of the Bloodthirster slowly slid apart along an extremely smooth and straight cut from his brow to his groin, splitting into two halves that fell to the left and right.

At the incision site, there was no gushing blood, only traces of being instantly evaporated and burned by extreme energy, and a faint glow from the Warp.

Immediately afterwards, a low, muffled sound emanated from within the two halves of the body, which then exploded, transforming into two surging torrents of scarlet energy that roared into Cato Sicarius's body.

In the "red sand" that rose from the sky, composed of pure Khorne energy.

Cato Sicarius slowly turned around, his blue-gold armor spotless, like a war god born from bloodshed, and walked out with steady steps.

He looked at Trajann, who was still somewhat dazed not far away, and solemnly said in his characteristic, absolutely confident tone:

"Stand up, Adeptus Custodes! Do not show any hesitation at this time."

With me, the Ultimate Sword Cato Sicarius, here, no one can harm your life.

Continue, serve the Emperor faithfully.

Trajann: "..."

His hand holding the halberd trembled almost imperceptibly.

The corners of his mouth, hidden beneath the mask, twitched forcefully.

These words... this tone... this damn, nostalgic yet infuriating sense of familiarity...

Isn't that the kind of line I used to say to those Space Marines recruits when I was on missions?!

Holy Emperor, please intervene! These are my words!
