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

Just as Shinazugawa Sanemi was thinking this, on another battlefield at the Demon Slayer Corps headquarters, Kokushibo stood proudly, surrounded by four Pillar-level swordsmen.

However, all four pillar-level swordsmen were injured at this time.

"You're not qualified to deal with me. Call Tanjiro out, all of you."

"I am," Kokushibo said coldly. (End of Chapter)

Chapter 289 The polarity reversal

Beimingyu Xingming had a compassionate expression, but his body was filled with a soaring fighting spirit. His cultivation robe was torn, revealing his strong muscles underneath.

When he faced Upper Moon One, Kokushibo, he realized just how formidable an opponent Tanjiro Kamado had truly been facing.

They were superior in both speed and strength. Most importantly, despite being surrounded by the four, Kokushibo remained completely at ease, seemingly without using his full strength.

Gyomei Himejima guessed that the other party was most likely on guard against Tanjiro Kamado.

However, according to the strategy set by Kagaya Ubuyashiki, Tanjiro Kamado should have already gone to another battlefield.

Now all they need to do is focus all their efforts on keeping Black Death here.

Thinking of this, Himejima Gyomei stomped his foot and quickly flew to the other side. At this moment, a blade appeared in front of him, which was Kokushibo's blade.

"Hmph, this power... it seems you've all grown quite a bit in the past two months."

Kokushibo glanced at the faint light swirling around the opponent's blade and let out a cold snort.

However, he recognized that this power was not the same power he had felt from Tanjiro Kamado before, since Tanjiro Kamado's power seemed to be inseparable from his flesh and blood.

However, he still believes that this power actually comes from Tanjiro Kamado, because the Breathing Technique that enabled the Demon Slayer Corps to fight against demons was created by his brother.

It's not impossible that someone like Tanjiro Kamado, who has developed a new technique, possesses another kind of power.

But for some reason, when he felt this power, a strong urge arose in his heart to crush and devour it.

Kokushibo didn't pay too much attention. After receiving Muzan Kibutsuji's gift, he felt that his body and mind would always have a strange impulse.

He guessed that it was very likely because he had not taken control of the body.

After all, having received two significant boosts within two months, it was hard for him to control his own power.

Thinking of this, Kokushibo couldn't help but feel a little regretful. If only Muzan Kibutsuji could have given him more time to adjust his power.

He believes his skills can be improved to a higher level.

However, he was already satisfied. The fact that Muzan Kibutsuji was so aggressive as to confront him head-on was enough to make him happy.

After all, Muzan Kibutsuji had been hiding for two hundred years. If the secret to overcoming sunlight hadn't been so close, he probably would have just waited for Tanjiro Kamado to die of old age.

Just as he was thinking about this, Kokushibo noticed that four Pillar-level swordsmen were attacking him again.

Without the slightest hesitation, he took a light step back, which instantly created a distance of several meters between him and the four Pillar-level swordsmen. Then, Kokushibo drew his sword and slashed at the ground.

Instantly, several jet-black, blood-red blade lights surged across the ground, as if a giant claw in the sky was reaching out to grab the crowd.

The Seventh Form: Mirror of Calamity: Moon Reflection

Kokushibo easily unleashed this sword strike, immediately disrupting the attacks of the four Pillar-level swordsmen, forcing them to use various methods to dodge the attack.

Kokushibo couldn't help but feel a little regretful. If it were before, this strike would definitely have killed all the Pillar-level swordsmen who hadn't activated their Marks. Unfortunately, now, with the support of that powerful force, the Pillar-level swordsmen were actually on par with those who had activated their Marks.

This strike, however, failed to kill these people.

However, these people in front of him still couldn't have any effect on him.

There was only one person he cared about: Tanjiro Kamado.

Kokushibo was puzzled. Although he was far from Akaza's battlefield, he could still easily see that the battle on Akaza's side was a crushing victory, and had already turned into a cat-and-mouse game.

Even so, why is Tanjiro Kamado still nowhere to be found?

What exactly was that person doing?

Meanwhile, at Kagaya Ubuyashiki's residence.

Kagaya Ubuyashiki and Tanjiro Kamado sat facing each other on the floor.

In the room next to theirs were Tamayo Nezuko and Urokodaki Sakonji and his group, who were considered among the more powerful members of the Demon Slayer Corps.

"It seems that Muzan Kibutsuji has made up his mind to send Upper Moons Kokushibo and Akaza to test your strength."

Kagaya Ubuyashiki had Yushiro's Blood Demon Art talisman on his forehead, giving him a clear view of the entire Demon Slayer Corps headquarters.

"As expected, Muzan Kibutsuji is still too cautious. If he were here now, he would definitely be able to deliver a heavy blow."

Kagaya Ubuyashiki's words were not without regret. From the beginning, he had guessed that Muzan Kibutsuji might be directly targeting Nezuko.

However, the entire Demon Slayer Corps headquarters has now been turned into a battlefield, and Muzan Kibutsuji still has no intention of showing up. It is clear that he is determined to wait for Tanjiro Kamado to make a move and to see Tanjiro Kamado's true strength before taking action.

"In that case, I'll leave it to Tanjiro."

Kagaya Ubuyashiki bowed to Tanjiro Kamado, feeling a pang of regret. Tamayo had told him that Muzan Kibutsuji had become incredibly cautious after being terrified by a swordsman two hundred years ago, and now it was impossible to wait for him to appear while the situation was still unclear.

If Tanjiro Kamado had been sent out to fight Kokushibo and Akaza earlier, perhaps the Demon Slayer Corps headquarters wouldn't have suffered so many casualties.

"Mr. Ubuyashiki, please don't mind. With such a formidable enemy at hand, it's only natural to be cautious. In that case, I'll be going."

Tanjiro Kamado stood up, and his eyes, which had been closed to rest, suddenly opened, flashing with an astonishing light.

He slowly walked out of Kagaya Ubuyashiki's room, and the moment he closed the door, he disappeared from the spot. When he reappeared, he was already on the wall of the Ubuyashiki mansion.

He looked up and saw Shinazugawa Sanemi and Uzui Tengen fighting and retreating, desperately dodging Akaza's attacks.

The moment Kamado Tanjiro saw Akaza, Akaza seemed to sense something, paused in his punching motion, and also looked at Kamado Tanjiro.

Their eyes met in mid-air, without any verbal or physical exchange, and then a fierce burst of fire erupted in an instant.

"Tanjiro!"

Akaza's voice sounded like it had crawled out of purgatory. He abandoned his attack on the two slippery Pillar-level swordsmen and stomped heavily on the ground, causing it to crack.

With each step Akaza took, the earth in front of him would crack open, and everything in his path would be shattered by his terrifying power.

In the blink of an eye, Akaza's speed had already surpassed his previous top speed, and like a whirlwind, he swept everything around him and flew towards Kamado Tanjiro.

Despite the overwhelming attack, Tanjiro Kamado remained unmoved and instead shook his head.

As Lin Yu once said, a person who specializes in martial arts should use their strength to the fullest in every move.

Actions like Akaza's, though grand in scale, are often more show than substance.

If you have more strength and speed than your opponent, you can easily defeat them.

So he only needs to do one thing here.

Tanjiro Kamado clenched his fists, and if you looked closely, you could see that his hands were now covered with a metallic sheen.

This was sent by Kagaya Ubuyashiki a month ago; it was made of a special metal mixture of "Gorilla Scarlet Sand Iron" and "Gorilla Scarlet Ore".

Tanjiro Kamado had never actually thought of this. He always thought of simply punching his opponent until they were unable to fight back, and then he could cut off their head whenever he wanted without any consequences.

Moreover, Lin Yu had been telling him that among the demons, there was Muzan Kibutsuji who broke through the barrier of not dying after being beheaded, and Kokushibo who also broke through this level. Then there was Akaza among the Upper Moon demons, who was only one step away from the entire level.

Therefore, whether or not Tanjiro Kamado has a Nichirin Blade is not important. As long as he has strength many times greater than his opponents, he can still beat them to a pulp.

Once the sun rises, no matter how tenacious the evil spirit's vitality is, it will turn to ashes.

However, after thinking it over, Tanjiro Kamado accepted the challenge. After all, the wounds inflicted by the gauntlets would weaken the demon's regenerative abilities.

Although the improvement is small, it's better than nothing.

Most importantly, with these gauntlets, he can completely abandon his somewhat awkward Nichirin Blade.

For Tanjiro Kamado, ultimately, he was more comfortable using his own fists.

While he was pondering, Akaza had already arrived in front of Kamado Tanjiro:

"Tanjiro, let me show you what I've been through these past two months!"

Akaza roared, his anger and powerful fighting spirit surging and merging into the punch in his hand.

Destruction Killing Style Modification

Akaza's eyes widened as the sinner tattoo on his body began to writhe, flowing around him like a small snake.

Before, the tattoo on the sinner was just an ornament, but after absorbing Muzan Kibutsuji's blood, it immediately became part of the power within his body. The blood energy was hidden in the tattoo, and when used, it would all burst out.

His current performance is a testament to the concentration of all his power.

Akaza poured all his power into this punch, with only one goal: to defeat Tanjiro Kamado.

He believed that no matter how strong Tanjiro Kamado was, he couldn't possibly be completely unaffected by a punch like that.

Even if Tanjiro Kamado could unleash a punch of the same power, his body would be the first to succumb to the impact!

Therefore, in this move, he was superior!

Akaza roared and threw a punch at Tanjiro Kamado, and then he quickly witnessed an unbelievable scene.

Tanjiro Kamado's calm face remained unchanged as he delivered a punch to Akaza without any fancy moves.

A powerful punch collided with Tanjiro Kamado's unassuming punch.

Sanemi Shinazugawa and Tengen Uzui, who had been watching the battle intently from afar, widened their eyes, eager to see what kind of earth-shattering clash would unfold.

Unfortunately, there was no sound or movement; only Tanjiro Kamado's fist passed through Akaza's arm without any hindrance.
