My clone invades all realms

Demon Slayer: World of Demons.

Roya suddenly opened his eyes as the icy waterfall crashed down on his head, washing over every inch of his taut muscles.

The biting cold made him even more awake.

He grabbed the long knife that was sitting still on the rock on the shore with his backhand.

hum.

The blade hummed softly, and an invisible force emanated from its body.

Without the slightest hesitation, he stood firm in the water like a rock, exerted his strength in his waist and abdomen, and with his long sword facing the cascading waterfall, he swung it upstream and slashed out!

"Azure!"

With a flash of light, a deep blue ribbon seemed to tear open the curtain of water, forcefully cleaving a gap in the surging waterfall for a moment.

Sunlight streamed through the brief crack, illuminating his face.

"Finally, I've mastered it."

Luo Ya exhaled a breath of stale air.

By the standards of the One Piece world, he can barely be considered a swordsman now.

Although it's only a rudimentary understanding, it's enough to make one feel invincible in that vast world.

Unfortunately, his true form is currently on the Grand Line, a place teeming with monsters, where swordsmen are hardly a rare breed.

"Not enough, far from enough."

Roya clenched his fists, the surging power captivating him, yet also fueling his resentment. He looked down at his chest, where a grotesque mark was branded—the hoof-shaped mark of a Celestial Dragon slave.

Each time he saw it, the humiliation and hatred burned even more intensely in his heart.

"Once I unlock my Nen abilities, or find a stronger power system in the next world... as long as I have enough strength to protect myself on the Grand Line, that will be the time for me to escape."

He leaped from the deep pool beneath the waterfall, splashing water everywhere, and landed steadily on the shore.

The clear pool water had no effect on him. This world didn't have anything like Seastone that could counter Devil Fruits; otherwise, his clone would have simply vanished upon the slightest touch.

Even if the main body is restricted by Seastone, all the clones that log into the other world will disappear directly.

"Ya-kun, the swordsmith has arrived!"

On the shore, Makomo was standing under a tree, her hands cupped around her mouth, shouting at him.

"Here you are." Luo Ya chuckled and walked over shirtless, seemingly unconcerned.

Water droplets slid down his sharply defined muscles, glistening in the sunlight.

Makomo's cheeks flushed instantly, and she quickly turned her head away, only daring to peek at him out of the corner of her eye.

Roya didn't seem to care. He walked over, picked up the folded Demon Slayer Corps uniform, put it on, completely covering the mark on his chest, and finally draped a dark red haori over his coat.

"Let's go."

He took the lead and walked ahead.

The two walked down the misty mountain path, and soon, the small wooden house came into view.

In front of the wooden house, Urokodaki Sakonji was talking to a strange man wearing a fire man mask. Hearing footsteps, the two of them turned around at the same time.

The next second, the masked man seemed to have springs under his feet, and his whole body turned into a blur, rushing straight towards Luo Ya in a cloud of dust.

"You! You're the monster rookie who single-handedly slaughtered the entire Wisteria Mountain?" Hotaru Hitsugaya's mask was almost touching Roya's nose.

"Too close!" Roya reached out a hand, pressed his face against it without any politeness, and pushed him back.

Hotaru Haganezuka staggered a few steps from the immense force, but instead of being angry, she became even more excited: "Wow! What incredible strength! It really is monstrous power! And this time there are two of them!"

"Let's go inside and talk," Urokodaki Sakonji said, walking into the house first with his hands behind his back.

"Weirdo," Makomo muttered under her breath from behind.

Luo Ya shook his head and followed him into the hut.

The four sat down around a low table, and Hotaru Haganezuka eagerly placed two long, cloth-wrapped objects on the table.

"Here, these are your Nichirin swords!" He carefully untied the cloth bundle, revealing two ancient-looking samurai swords in their sheaths.

"The raw materials for the Nichirin Blade are 'Scarlet Sand Iron' and 'Scarlet Ore' collected from the mountain closest to the sun. The steel forged from them can absorb sunlight!" Hotaru Hagane's arms danced like waves, spittle flying everywhere.

"It's also known as the 'Chameleon Blade'! Quick, draw it and see! What color will a monster like you turn? I can't wait!"

"Calling someone a monster is going too far," Makomo said, standing up for Roya.

Hotaru Haganezuka suddenly brought her face close to Makomo's, startling her so much that she leaned back.

He pointed at Roya and said matter-of-factly, "Look at any new recruit in the Demon Slayer Corps, can he fight Lord Urokodaki to a draw before even formally learning the Breathing Technique?"

"Cough cough!" Urokodaki Sakonji coughed heavily twice beside him.

Hotaru Haganezuka turned her head and looked at him innocently: "Why are you coughing? Didn't you tell me that yourself?"

"Cough cough cough cough!" Urokodaki Sakonji coughed even more violently this time, as if he had really choked. His old face under the tengu mask probably couldn't hold up anymore.

This guy really doesn't give you any face at all.

Luo Ya ignored the two clowns; his attention was entirely focused on the knife in front of him.

He gripped the hilt and slowly drew the knife.

Clang——

The blade was drawn from its sheath, initially just the color of ordinary steel, but the moment Roya gripped it tightly in his hands, a sudden change occurred.

A splash of bright red appeared from the hilt of the sword, like blood dripping into clear water, and quickly spread upwards. In the blink of an eye, the entire blade of the sword was stained with an eerie and intense red!

"Red! It's red!!!" Hotaru Haganezuka slammed her hand on the table and jumped up, letting out a piercing scream, "Waaaaah! I finally got a red sword!!"

He acted like a madman, lunging forward to snatch the knife.

With a flick of his wrist, Luo Ya casually swung the knife.

call!

The sharp blade brought a gust of wind, grazing the tip of Hotaru Hitsugaya's nose, the cold sharpness making him freeze in place.

Hotaru Hitsugaya stopped moving and looked at Roya, meeting the boy's wide grin.

That smile was radiant, yet for some reason, it made his heart sink suddenly.

Not right.

This boy is very strange.

That aura... it's the aura of someone who's killed people, and not just one or two.

The swordsmen of the Demon Slayer Corps only slay demons, not humans. Their killing intent is pure and directed at evil spirits.

But the faint smell of blood on the boy, and the look in his eyes that flashed just now...

That's not the look a teenager should have.

He quietly poked Urokodaki Sakonji next to him with his finger.

Urokodaki Sakonji remained silent. When he first met Roya, he only thought of him as a boy who worshipped power and was exceptionally talented.

But now, what's with this intense, almost tangible, stench of blood?

During this time, Luo Ya was clearly under his nose, so there was no way he could have had the opportunity to kill anyone.

Moreover, the level of stench that can be created is definitely not something that can be achieved by killing a dozen or so people.

That was the aura of death accumulated from the deaths of hundreds of people.

Urokodaki Sakonji's brows, hidden beneath his mask, furrowed tightly.
