What do you mean you don't have it...?" hissed Muzan, her tone resembling newly erupted molten lava, ready to devour anything in its vicinity.
However, Muzan's anger did not make El feel the least bit afraid or daunted. His face remained cool, her demeanor as calm as the ripple-free water of a pond, unshaken by any threat.
With a casual gesture, El swung his hand and took out a single syringe filled with red liquid, blood that had the power to transform humans into demonic figures comparable to origin. He displayed the syringe in front of Muzan's eyes.
"But," El said, pausing, letting his sentence hang in the air. "I have something that gives a similar effect to the Blue Spider Lily Flower."
"That..." Muzan's eyes tightened instantly at the sight of the syringe. Even the cells and blood in his body, which had never shown fear, reacted. It felt as if they were screaming, craving the liquid with an unbearable thirst.
Unable to resist, Muzan immediately rose from her throne, walking slowly towards the edge of the platform.
Muzan's eyes were filled with greed, his body as if driven by the most primitive instincts. "Give me that thing!" he said firmly, his tone commanding, revealing a thirst that could not be contained.
Kokusibo instantly reacted to Muzan's desire, his hand quickly reaching for the sword at his waist, followed by Doma and Akaza who prepared to attack, with the aim of seizing the object in El's hand.
However, in a split second, El put the blood-filled injection back into the Item Storage Ring. Instead, he took out three empty 10 mm syringes.
The demons that were there were momentarily surprised, stopping their intention to attack. Including Muzan, whose gaze now turned from greed to confusion. They all looked more seriously at El, wondering what this human was going to do.
"Give me your blood first," El said calmly, throwing the three empty syringes one by one to Muzan, Kokusibo, and Doma.
With very quick reflexes, they caught the syringes without difficulty, their expressions showing a deeper curiosity.
Seeing El's actions, Akaza felt as if he was experiencing dejavu. He was reminded of a similar incident he had experienced before. 'Is this going to end like that time?' Akaza thought, lost in thought, trying to guess what would happen next.
On the other hand, Kokusibo and Doma remained silent, awaiting the decision of their master, Muzan. Would he give his blood or choose to attack and seize the object that claimed to turn humans into demons?
Doma smiled faintly, his mind filled with speculation. 'Hmm... Interesting human,' he said to himself, 'Unfortunately not a woman, so I'm not interested in eating hos flesh.'
'What is this human asking for demon blood for?' thought Kokusibo, thoughtfully, as if trying to understand the motive behind El's request.
Although their thoughts differed, there was at least one thing they were sure of. Even if El tried to hide that thing somewhere on his body, they felt certain that they could find it.
For them, killing El and examining his body from head to toe was the quickest solution to finding it.
Meanwhile, in his mind, Muzan traced Akaza's memories. 'Why does this human want demon blood? Is he trying to become a demon? But doesn't he already have a potion that can transform him?'
For a moment, Muzan stopped analyzing, then with full confidence, thought, 'Whatever the reason, as long as I'm immune to sunlight, I've become perfect!'
With a cold stare, Muzan refocused his attention on El, considering the next step he would take.
After a moment of silence, Muzan decided to extract his blood. Seeing that action, Kokusibo and Doma immediately followed suit, each extracting their blood without hesitation.
After three injections full of demon blood, the injections were thrown back at El. Deftly, El caught the injections and stored them in his item storage ring.
After accomplishing that, El drew his sword calmly, his gaze full of seriousness. "Fight me, kill me, and I'll give you that thing."
Without hesitation, Muzan issued a cold order, "Kill him."
Kokusibo moved at lightning speed, swinging his sword with the intention of finishing El off in one slash. Kokusibo's movements looked slow to El, but he chose not to dodge.
Instead, El blocked the slash with Metsu, wanting to gauge how far his power range was without activating the Demon Slayer Mark first, against the strongest Upper Moon Demon.
Dang!
A loud bang was heard as their swords clashed. However, the impact sent El flying away from where she stood, hitting the walls and corridors of the buildings inside Infinity Castle with great force.
While still on the ground, El muttered to herself, "My hand went numb. Kokusibo's power is much greater than Akaza's, he must be at the peak of Authority level 5," he thought, enduring the pain that spread through his hands from withstanding Kokusibo's attack.
El immediately twisted his body in the air, corrected her posture and took a gentle foothold on the wall behind his. With one powerful stomp, he jumped with incredible speed, heading for the nearest wooden corridor.
Reaching the corridor, El prepared to jump back towards the platform where he had fought earlier. However, there Akaza was already waiting for him, grinning while swinging his deadly fist.
"We meet again, Adrian!" said Akaza enthusiastically and then unleashed his threatening and devastating fist attack, "Mesattsu!" Akaza exclaimed seriously.
El remained silent, not answering any of Akaza's words. With Rinnegan's Eye of Insight active, El could predict Akaza's movements with ease, reading his steps as if they were already written in front of him.
Shing!
El swung Metsu quickly, anticipating Akaza's attack. Akaza was forced to change his position, bringing his hands together to deflect El's slash that came with tremendous force.
Dang!
A loud bang was heard as Metsu collided with Akaza's arm, sending him flying far away, hitting several floors, walls, and the wooden corridor behind him. His attack failed miserably.
Suddenly, without warning, Doma appeared behind El, holding both of his war fans. Deftly, he swung his fan and said, "Kesshō no Miko," creating four ice miniature replicas of himself that instantly surrounded El from all sides.
The four miniature Doma, complete with ice fans in their hands, swung their weapons as fast as the wind, trying to attack El simultaneously. However, El was undeterred.
Lowering his body into a low position, El swung his sword in one perfect circular motion, slashing all around his.
"Heki-ra no Ten," El said, cold and stern, radiating a serious aura.
Shing!
A cold flash shot out from El's slash, shaking the surrounding air. In an instant, the heat that followed created a blazing ring of fire, encircling him.
With unimaginable force, one slash unleashed a kinetic wave that swept away all four Doma replicas.
They disintegrated completely, miniature ice fragments disintegrating helplessly before they could get close to El. This slash also cut through Doma's body from the waist down with deadly precision, splitting him apart mercilessly.
Doma was shocked by this. However, before Doma could react, El had already launched a spinning kick like a whip swinging, hitting Doma's torso with tremendous force.
Doma was blown away like a kicked ball, his body slamming into the walls, floors, and wooden corridors of Infinite Castle, making a loud noise every time he hit a surface.
Suddenly, beside El, Kokusibo appeared quickly. He swung his sword in a steady motion and said, "Ichi no kata: Yamidzuki - Yoi no Miya."
Its horizontal slash formed a crescent arc followed by dozens of crescent blades that spread chaotically along its path, ready to destroy anything in its way.
Seeing the attack, El immediately jumped as high as she could, dodging to keep a safe distance from Kokusibo's slash. In a voice as calm as flowing water, El said, "Gen'nichi Kō."
In an instant, El's body seemed to distort and disappear from where he stood, leaving behind a blurry shadow.
El reappeared in the wooden corridor defying the laws of gravity, in a position much safer from Kokusibo's reach, watching from a distance calmly.
