On the other hand, Akaza and Doma's eyes were unable to catch El's movements, which seemed to be swallowed up by time and space. They could only strengthen their surveillance, especially Akaza, who sensed the approaching danger.
Quickly, Akaza increased the use of the Demon Blood Art, Rashin to detect El's movements from all sides. Akaza manifested a light blue snowflake-shaped compass underneath with numbers ranging from 1 to 12.
This technique allows Akaza to sense the Fighting Spirits of living creatures, except for plants within his area. strengthens his sixth sense and helps him sense changes in the atmosphere.
Meanwhile, Doma, though seemingly relaxed, remained vigilant, focusing on every movement that occurred around him.
Although the smile on his face suggested calmness, his eyes remained sharp, ready to respond to any threat that arose.
Suddenly, El's figure appeared silently behind Doma, swinging his sword in one swift, decisive motion. Metsu's crimson flashes rubbed up against the air, creating flames along its path.
Doma's demon blood splashed in the air creating beautiful sparks, yet very frightening for the Devil.
In an instant, Doma's vision began to spin, making him feel momentarily confused. 'Eh? The world is spinning? How can that be?" he thought, stricken with confusion.
It was only after his head fell to the floor and rolled, that Doma realized that his head had separated from his body and his consciousness tried to make sense of it, but it was too late.
Slowly, Doma's head began to crumble into dust, while his eyes still held a look of shock and observed his body that stood upright but slowly faltered, then collapsed to the floor.
"I was decapitated?" muttered Doma, confused, before a warm smile appeared on his face. "Not bad," he said, as if appreciating the attack that had just made him lose his head.
Suddenly, El got a holographic interface notification in rapid succession.
Ding!
[Beyonder with serial number 120,000 has successfully completed level A side mission, -Invasion of Infinite Castle -]
[+25,000 points]
Ding!
[System detects, Beyonder with serial number 120,000 has completed all Main Missions]
[You can return to the Rencarnation room, or stay in this world]
[If you choose to return to the Rencarnation room, then you will undergo Evaluation and reward calculation]
[If you choose to stay in this world, you can stay for 3 days]
El glanced at the system notification and said coldly in his mind, 'System, I chose to stay for 3 days. At least before leaving, I have to further reduce Muzan's strength.'
Meanwhile, seeing that Doma's head had separated from his body, Kokusibo and Akaza just stood still, but their eyes were now much sharper, watching El's every move with increasing vigilance.
In the tense silence, they did not exchange glances, but realized that El was not an opponent to be underestimated.
Amidst the mounting tension, they prepared for El's next move, their bodies on full alert, like two predators watching for deadly prey.
El stood still for a moment, after finishing off Doma, then operated the system notifications quickly before turning his gaze towards Kokusibo and Akaza. "So... who's next?" he asked, his voice cold and sharp, breaking the tension that hung in the air.
Grasping Metsu tightly, El made the pressure even stronger, causing the red blade to glow even brighter, sizzling and vibrating the air around it due to the heat it radiated.
El pointed Metsu's blade downward, with her body low, right knee bent, and back leaning slightly forward in a low stance full of intensity.
Seeing this, Kokusibo and Akaza strengthened their stances, their awareness on full alert. Although their thoughts were usually at odds, this time they agreed inwardly: "El is a very dangerous opponent."
Kokusibo looked deeply at El, and in his vision, El's figure began to overlap with the image of his brother, Yoriichi Tsugikuni. 'I hate to admit this, but he... looks like my brother,' he muttered to himself, full of tension and annoyance.
On the other hand, Akaza felt a flash of memory that was foreign to him. "These are not my memories... but Muzan-sama's. Who exactly is that person?" he muttered as she settled into a Soryu stance, directing her full energy at the figure in front of her.
El pressed his feet firmly into the floor, crushing it with tremendous force. However, his breathing suddenly became labored, and he coughed up blood, his body staggering. Despite this, El tried to hold on by relying on Metsu for support.
This made the six Tomoe on the Rinnegan orbiting around his disappear one by one. "My calculations were wrong, my body has reached its limit..." she muttered, her face showing a hint of worry.
Seeing El who suddenly weakened and coughed up blood, Kokusibo immediately checked the blood flow in El's body with the Translucent World technique.
Meanwhile, Akaza felt that El's fighting spirit was fading like a fire in the wind.
Realizing that this was the best opportunity to strike, Kokusibo immediately launched his attack. Akaza followed quickly, preparing his Blood Demon Art.
Akaza began his Blood Demon Art with a serious look in his eyes. "Jutsushiki Tenkai," he said in a low but firm voice, assuming a typical Soryu Style stance.
Bending his knees in a half-squat position, Akaza kept his body perfectly balanced. His right arm extended forward, a half-clenched hand facing him, while his left arm bent at the side with an open palm, ready to parry or strike at any moment.
Kokusibo suddenly created a sword of his own flesh and blood, emitting an intimidating aura. "Tsuki no kokyū," he said in a cold voice, like moonlight piercing the darkness of the night.
With one decisive swing, the blade extended abruptly, aiming directly at El. "Shichi no kata: Yakkyō - Zukibae," he muttered, as a crescent-shaped slash raced by.
A wave of sharp, curved strikes was created, which shot straight ahead, followed by tiny blades of blood that moved quickly to kill.
El, who had almost finished operating the system for Reward Evaluation and Calculation, "Damn!" he muttered, and was forced to stop the process to focus on dealing with Kokusibo's brutal attack.
Dang!
The inevitable loud bang was created and echoed as El blocked Kokusibo's attack with his sword.
However, the overwhelming force of the attack caused both of his arms to break, while his skin was shredded by the small knives included in Kokusibo's slash. El's body bounced away, hitting the floor hard.
Not letting up, Akaza continued with his Demon Blood Art, unleashing a barrage of precise punches. "Shūshiki: Aogin Ranzankō!" he cried, unleashing a hundred sharp shock blows from various directions almost simultaneously.
With both arms already immobilized, El could only withstand the wave of brutal blows with his body. "Argh..." he whimpered, his body shaken and in pain. Several of his ribs were cracked, and his internal organs were severely injured under Akaza's relentless attacks.
El forced his body to spin in the air, trying to improve his position to stand up despite her already weakened condition. His breathing was heavy, but his gaze remained sharp, looking at Kokusibo and Akaza who now stood before his.
"Just surrender... give me the blood," Kokusibo said, his voice cold and emphatic. "You're amazing... I promise I'll give you a painless death."
On the other hand, Akaza's expression showed a sense of discomfort, as if his heart was being torn apart at the sight of El's badly injured body. "Adrian, just give up. I can no longer bear to see a fighter as strong as you die like this."
In a serious and decisive tone, Akaza added, "Give me the blood, and let me or Kokusibo end this painlessly for you."
