"Could it be!"
Uzui Tengen's face darkened.
He had completed his musical score, elevating his combat power to its peak. Once the opponent made a mistake, his head would be severed.
In such a critical situation, this guy was still holding back. How big was his heart?
"It's my turn to attack!" Kamihara Tetsuya said in a hoarse voice. This would be his final assault.
To recover from his severe injuries, the souls stored within his body were nearly depleted.
At most, only about ten were left.
Pei Lang and Kamanue's Blood Demon Art could directly increase his strength. These two souls could only be consumed as backup energy as a last resort.
"Thunder Breathing: Fourth Form: Distant Thunder!"
Blood-colored lightning erupted from Kamihara Tetsuya, moving like thunder, rapidly closing in on Uzui Tengen.
"One!"
"Two!"
"Three!"
Uzui Tengen couldn't fathom what hidden techniques his opponent possessed. He could only follow the musical score he had calculated earlier, his chained dual swords dancing fiercely in his hands.
He swung his dual swords, directly meeting the incoming attack.
It was still the same strange angle as before. If it were the Kamihara Tetsuya from moments ago, he would only be able to dodge, or even fall into a predicament.
However, after incorporating Armament Haki...
Everything changed!
Bang! Bang! Bang!
Kamihara Tetsuya neither dodged nor avoided, swinging his Haki-infused dual blades, sending countless sword slashes through the air.
The gunpowder balls Uzui Tengen threw in mid-air were cut into pieces, followed by violent explosions.
The hardness of the Haki-infused dual blades was further enhanced. Uzui Tengen's gunpowder balls could no longer destroy Kamihara Tetsuya's body as they had before.
With the support of Armament Haki, Kamihara Tetsuya's fighting style instantly transformed, becoming much more aggressive.
A small change was enough to disrupt the entire musical score.
"The chords are messed up!"
Uzui Tengen keenly noticed the change, thinking to himself that it was bad. He had to restart his calculations.
This required time.
But Kamihara Tetsuya wouldn't give him any more time!
Since he had received the reward from the dog system, Kamihara Tetsuya had no desire to continue the fight. He wanted to finish off Uzui Tengen as quickly as possible.
"Thunder Breathing: Sixth Form: Electric Rumble and Flash!"
Kamihara Tetsuya's blade-like hands were wreathed in blood-colored lightning. In an instant, he unleashed countless lightning-shaped slashes towards Uzui Tengen, the blood-colored lightning crackling and popping.
Blades and shadows, overwhelming.
"Hmph!"
Uzui Tengen's face was grim. At this moment, he could only brace himself and swing his dual swords.
Bang! Bang! Bang!
The sword slashes of both clashed fiercely, crisscrossing in all directions, leaving countless marks on the ground.
In the tense battle, Uzui Tengen inadvertently caught sight of the blood-colored eyes beneath the mask.
Sharingan · Genjutsu!
The moment their gazes met, a blood-colored light flashed in Kamihara Tetsuya's eyes, and a continuous stream of ocular power surged forth.
"Not good, it's a Blood Demon Art that traps people in illusions!" Uzui Tengen was startled, immediately recalling the information provided by Muichiro Tokito.
If he were dragged into an illusion, even for just a second, it would be enough for him to die a dozen times over.
No matter what, he had to stop the opponent!
Uzui Tengen steeled himself, his body trembling slightly, and the gunpowder balls hidden in his clothes all fell out.
A strong smell of gunpowder assailed his nostrils. Kamihara Tetsuya glanced at them; there were easily over a hundred gunpowder balls. He truly wondered how the other party had managed to hide them all.
Bang!
The clash of blades created a fierce gale, tearing at the gunpowder balls suspended in mid-air, causing sparks to fly.
"A self-destructive attack? Then I'm not interested in playing with you any longer." Kamihara Tetsuya saw that Uzui Tengen was also within the explosion range. The opponent had revealed his true intentions.
Decisively, Kamihara Tetsuya retreated rapidly.
"Even if I die, I'll drag you with me!" Uzui Tengen roared, almost crazed.
Kamihara Tetsuya cursed inwardly, 'Ruthless enough!'
Whoosh!
Kamihara Tetsuya's eyes widened, the two tomoe spinning madly, and a crimson light burst forth from his eyes.
Uzui Tengen instinctively closed his eyes.
This one-second gap was enough for Kamihara Tetsuya to retreat several dozen meters.
Boom!
Hundreds of gunpowder balls exploded in succession, becoming the final crescendo of this fierce battle. The flames were brilliant, and waves of scorching heat surged higher and higher, engulfing an area of several hundred meters.
Kochou Shinobu, Sanemi Shinazugawa, and a group of Demon Slayer Corps members who had already reached the foot of the mountain looked up.
Their pupils reflected the firelight that dyed the clouds red, and they felt a sense of shock. The battle above had not yet ended.
They dared not hesitate and quickly surrounded the area.
...
"Hmph! Hmph!"
Kamihara Tetsuya used his Divine Transformation to form a shield, infused with Armament Haki, blocking in front. In the direct collision, the immense pressure forced him to retreat continuously.
The high-temperature flames burned the shield red. If nothing unexpected happened, he would lose another pair of hands.
When all the dust settled.
Kamihara Tetsuya found himself pushed back a hundred meters by the surging air currents, leaving a grotesque trail.
He looked up at the center of the explosion.
"Pfft!"
Uzui Tengen lay on the ground, spitting blood, his entire body covered in burn marks, on the verge of death. However, he still retained consciousness, biting his teeth tightly.
"Hmph! Hmph!"
Kamihara Tetsuya knelt on the ground, tearing off his charred hands, his stamina almost depleted.
Soul Manipulation: Devourer!
He gritted his teeth, once again transforming two souls into energy and devouring them. New flesh slowly grew from his hands.
Even with a continuous supply of energy, Kamihara Tetsuya was still struggling. The intense combat was incredibly draining on his spirit.
On the horizon, a faint whiteness appeared.
Purple Wisteria Mountain was engulfed in a sea of fire, burning the sky red, making it easy to misjudge the time.
By now, an entire night had passed, and there was less than half an hour until sunrise.
Dense footsteps came from the foot of the mountain.
More Demon Slayer Corps reinforcements had arrived.
"You're lucky, you got to keep your life!" Kamihara Tetsuya said in a hoarse voice.
After speaking, Kamihara Tetsuya turned and left.
"Don't think about escaping…" Uzui Tengen struggled unwillingly, reaching out forward, but he couldn't move.
Kamihara Tetsuya dragged his exhausted body, quickly traversing through the sea of fire, fleeing in the opposite direction.
As long as he left this area and removed the Crimson Moon skin, he would be worry-free.
Muichiro Tokito and Uzui Tengen had fought against Demon Yasuo, and he had not appeared at all during that time.
Under normal circumstances, he would definitely be suspected.
But sunlight was the undisputed natural enemy of demons!
As long as he appeared under the sunlight, the Demon Slayer Corps would absolutely not associate him with demons. At most, his evaluation for not appearing to fight would be lowered.
He escaped the sea of fire and fled all the way to the back of the mountain.
Kamihara Tetsuya let out a sigh of relief, the blood-colored light on his body dissipated, and the effect of the Crimson Moon skin was removed.
From this moment on, he was no longer the infamous Demon Yasuo, but the swordsman Kamihara Tetsuya.
It was also at this moment that a voice, smaller than a mosquito, suddenly sounded in Kamihara Tetsuya's ear.
"Tetsuya-san, are you a demon?"
