Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

As soon as he finished speaking, a thick blade of light appeared, carrying a faint aura of blood, and condensed into the shape of a crescent moon.

This strike was incredibly fast, honed to its limit by Kokushibo.

First Form: Dark Moon: Night Palace

His body and the three pairs of eyes on his face were all firmly locked onto Tanjiro Kamado.

He believed that with so many eyes watching, Tanjiro Kamado was already doomed from the attack.

The fragile human body certainly couldn't withstand this sword strike, and Tanjiro Kamado's only choice was to fight it head-on.

Just as Kokushibo had predicted, Tanjiro Kamado showed no intention of backing down. Instead, he took a step forward, did not draw his Nichirin Blade, but instead clenched his fist and threw a punch forward.

Just like him, there were no fancy straight punches; both the slash and the punch were extremely simple.

The only competition is between their strength and speed.

"Is that how it is? Very well, now you'll see the difference between us for what it is!"

"Kuroshibo said in a deep voice."

As soon as the words were spoken, the two collided violently.

"Ding!"

The crisp sound of metal clashing was heard.

Akaza, who was waiting for his chance to make a move, kept his eyes wide open, watching to see how this attack would turn out.

The two were instantly separated.

Tanjiro Kamado remained unchanged, but Kokushibo's pupils suddenly contracted.

Because he saw that the blade formed by his own blood had developed a crack and then suddenly broke at the break point.

"Your power..."

Kokushibo said in a deep voice that he had sensed that Kamado Tanjiro's power was extremely strong before, but at that time Kamado Tanjiro was overwhelming him, so he did not feel it in detail.

He could now clearly sense that the distance between himself and Tanjiro Kamado was not as great as before, but only now did he realize just how vast the difference in power between them truly was.

"I've already said, in your current state, you're no match for me."

"It's Tanjiro Kamado," he said coldly.

"How could I possibly lose if I'm no match for you?"

Kokushibo raised his head, and countless eyes on his body stared intently at Tanjiro Kamado.

"Then let me show you what kind of power a demon really has!"

As soon as he finished speaking, the kimono covering Kokushibo's body suddenly exploded, and countless blades emerged from all parts of his body. The blade in his hand also transformed into a multi-bladed sword.

His entire body had transformed into a monster.

"I'm willing to give anything to defeat you."

Kokushibo shouted loudly, his aura surging, and every muscle in his body tensed up.

Then, with a sudden movement, he vanished into thin air.

Tanjiro Kamado's expression shifted slightly, and a hint of interest finally flashed in his eyes. The next second, his figure disappeared from the spot.

Meanwhile, countless clanging sounds of metal clashing rang out in the air, accompanied by bursts of sparks.

Akaza felt completely powerless to intervene.

He was unaware that Kokushibo had become so powerful after receiving Muzan Kibutsuji's gift.

This made him extremely unwilling, but despite his resentment, he kept his eyes fixed on the source of the firelight and sounds, trying to avoid missing any details.

Just as the sound of metal clashing was about to merge into the sound of rain, Akaza's pupils suddenly contracted.

Because he actually heard a crisp snapping sound amidst the rain.

Then a blade with an eye embedded in it grazed his cheek and came to rest against the wall in the distance.

It shouldn't be said that it was a definite cut; rather, the blade pierced into the wall as easily as cutting through tofu.

Then, after a while, he saw more blades flying out from the place where the flames were bursting continuously.

Immediately, two dark figures reappeared in Akaza's field of vision.

Akaza watched the two of them nervously, wanting to know the outcome of the collision.

When Akaza saw the two people clearly, his pupils shrank.

At this moment, Kokushibo was panting heavily, staring intently at Tanjiro Kamado opposite him. The multi-bladed sword in his hand was already broken and damaged, with only half of the blade remaining, making him look extremely disheveled.

Tanjiro Kamado barely caught his breath, and although his clothes were slightly torn, there was no trace of blood on them. He calmly looked at Kokushibo.

"How can this be?"

Akaza exclaimed in surprise.

How could Tanjiro Kamado have maintained such a state after such an attack?

Human endurance shouldn't be weaker.

Could it be?

A terrible thought arose in Akaza's mind.

Could it be that Tanjiro Kamado wasn't actually using his full strength the whole time?

Akaza felt a sense of fear rise involuntarily.

At this moment, Kokushibo's eyes were also filled with disbelief:

"I didn't expect you to be so strong. I underestimated you."

As soon as he finished speaking, Kokushibo spat out a mouthful of blood, staining the ground beneath his feet red.

His heart was filled with resentment, because he had done so much, yet he still hadn't defeated Tanjiro Kamado.

Tanjiro Kamado is too strong, but is he really going to give up like this?

Kokushibo's vision blurred. Just now, in order to capture Tanjiro Kamado's movements, he had undoubtedly raised his concentration to an extremely high level.

Now it's him who's finding it hard to keep up.

Even through his blurred vision, he could clearly see the hint of pity in Tanjiro Kamado's eyes.

The flame that had been extinguished by the defeat he had just experienced suddenly reignited in his heart.

A voice cried out in his heart:

He can't lose!

"No, I can't lose, how can I lose to a boy like this..."

The sound of despair, like a whisper from the bottom of a well, sent chills down one's spine.

He felt something was being released within him.

More blades pierced out of his body, but quickly lost their blade shape and turned into pure flesh and blood.

Flesh and blood swirled, transforming into primal spikes.

Tanjiro, I will defeat you!

Kokushibo roared, and his body suddenly moved, even faster than before.

Tanjiro Kamado's eyes showed even more pity this time.

Seeing Tanjiro Kamado's gaze, Kokushibo's inner turmoil intensified, and his boundless rage ignited his reason.

With a powerful push of his feet, he charged towards Tanjiro Kamado like a cannonball, his speed increasing by a whole new level.

He opened his mouth, which was now covered in spikes, and let out a roar like that of a wild beast.

"He has completely turned into a monster."

Tanjiro Kamado sighed softly, took a step forward, and then made the simplest gesture.

He raised his arm and threw a punch. (End of Chapter)

Chapter 291 Tanjiro Kamado's Combat Strength Test

"Die!"

Kokushibo's sanity was being eroded, and the roar that came from his throat was like the howl of a wild beast, echoing throughout the entire Demon Slayer Corps headquarters.

Even the demons, Demon Slayer Corps members, and Pillar-level swordsmen engaged in fierce battle couldn't help but turn their attention to the fight between Kokushibo and Kamado Tanjiro.

The two people, moving so fast they were almost invisible, collided in mid-air.

"Boom!"

The deep, muffled sound was like a monk striking a grand bell; after a loud bang, there was a continuous, resounding chime.

boom!

The building beneath their feet could no longer withstand their attack and collapsed with a crash.

The battle between the two suddenly shifted from the rooftop to the ground.
