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

Wherever they went, the ground cracked and buildings collapsed due to their terrifying power.

Many demons and Demon Slayer Corps members who were on the battlefield far from the two of them kept their distance to avoid being caught in the crossfire.

Akaza is now completely indifferent to the outcome of the battles between the other demons and the Pillar-level swordsmen.

Because he understood that these demons were actually expendable resources, their lives were worthless, and Muzan Kibutsuji could create countless of them if he wanted to.

But beings like Kokushibo are already extremely rare.

At least his combat strength is at the Akaza level, which is absolutely unattainable.

If Kokushibo can't defeat Tanjiro Kamado, then which new demon can be competent for this task?

Unless Muzan Kibutsuji is willing to take action himself, but it's clear that he doesn't want to take any risks, it's impossible for him to do so. We can only wait and see if Kokushibo can defeat Tanjiro Kamado.

Soon, the speed of their fight gradually slowed down.

Clearly, their condition was gradually deteriorating, as such high-intensity movements would be a huge drain on their physical strength.

Kokushibo stared at them, his heart filled with anxiety.

Finally, the two figures gradually appeared in front of the person and then separated.

Who won?

This thought arose in Akaza's mind, and then his pupils contracted.

This time, he finally saw Tanjiro Kamado breathing heavily, with a faint bloodstain on his face, clearly left by Kokushibo.

However, it was clear that Kokushibo, who was standing opposite him, was in a worse state.

If Kokushibo's previous appearance was terrifying, then his current appearance is completely miserable.

All the fleshy spikes that had previously grown from his body had now been broken off.

Inside the tattered clothes were countless bloodshot eyeballs that had been exploded.

Blood-red liquid nearly covered Kokushibo's body, and even half of Kokushibo's head was smashed by a punch, but Kokushibo remained motionless.

Lost?

A sense of despair rose in Akaza's heart.

However, he soon realized something was wrong: Kokushibo in front of him showed no sign of falling.

If you look closely, you can see signs of flesh wriggling on the other person's body, and his cracked skin and eyes are gradually healing.

While Kokushibo is no match for Tanjiro Kamado in terms of direct combat strength, his advantage lies in the latter's terrifying regenerative abilities.

Akaza knew from the beginning that Kokushibo had already broken through the limit of being able to be reborn even if his true nature was seen through.

This alone shows just how strong Kokushibo's regenerative abilities are. And now, having obtained Muzan Kibutsuji's blood multiple times, Kokushibo's regenerative abilities have undoubtedly been greatly enhanced.

Now it seems that Kokushibo has indeed been enhanced, and can perform this level of treatment even with a damaged skull.

Tanjiro Kamado is different. After all, his body is just a human body, so how could he possibly have the powerful regenerative ability of a demon?

If Tanjiro Kamado cannot kill Akaza in one go, then one day, Tanjiro Kamado will be killed by Kokushibo.

Thinking of this, Akaza quickly rushed to Kokushibo's slowly recovering body and stared warily at Kamado Tanjiro.

Tanjiro Kamado ignored Akaza and didn't think about how to kill Kokushibo.

Because in the previous exchange, he realized that his strength and speed were not enough to overwhelm the opponent.

He did more than just sigh.

"As expected, using only internal energy is still not enough."

Watching Kokushibo gradually repair his body.

Tanjiro Kamado also introspects on his own body.

He appeared very calm in his battle just now, but the process was actually extremely dangerous.

Kokushibo still caused him a lot of trouble.

Several times, he had to endure a punch while simultaneously delivering one to Kokushibo.

Although it wasn't a very serious attack, it still had some impact on Tanjiro Kamado's condition.

He even suffered some internal injuries as a result.

However, these internal injuries have been completely healed under the nourishment of internal energy. Although there is still blood on his surface, he is in very good condition now.

Although Lin Yu's prescription did not turn it into an indestructible monster, and its ability to withstand blows was not as good as Kokushibo's, what pleased Tanjiro Kamado the most was its healing ability.

Previously, when he used his internal energy to heal his injuries, the process was often extremely slow.

As a result, the healing power of internal energy has become extremely strong.

This regenerative ability is comparable to that of some weaker evil spirits.

Even in this state, Tanjiro Kamado was already quite satisfied.

As for why he didn't use it, it's because Tanjiro Kamado wanted to test his current strength.

Although he had previously expressed his desire to spar with Sanemi Shinazugawa, this was after Tanjiro Kamado had been in seclusion for over ten days, taking medication and training.

He realized that with his current powerful internal energy, he had completely overwhelmed Shinazugawa Sanemi in terms of strength.

At this point, going to find Sanemi Shinazugawa to test one's strength is somewhat pointless.

Therefore, from the very beginning, Tanjiro Kamado treated his battle with Kokushibo as a test.

He wanted to see just how strong he was now without using his emotional power.

It seems that Tanjiro Kamado is still somewhat dissatisfied, since he is only slightly stronger and faster than Kokushibo.

He was of course unaware that Muzan Kibutsuji had significantly enhanced Kokushibo in order to deal with him.

So he still remembered what Lin Yu had said before: Muzan Kibutsuji was many times stronger than these Upper Moons.

As Lin Yu had mentioned before, emotional power is a kind of external force. If his internal strength is not strong enough, he will not be able to withstand more emotional power.

Therefore, Tanjiro Kamado always regarded his own internal energy and his trained physique as his strength.

However, it seems that if he doesn't use his emotional power, he is no match for Muzan Kibutsuji.

This is definitely different from what Tanjiro Kamado had expected.

But that's all we can do.

Tanjiro Kamado shook his head.

While Tanjiro Kamado was pondering, the Pillar-level swordsmen who had been observing the outcome of the battle were getting anxious.

They were unaware that Tanjiro Kamado had not yet gone all out. They had been observing, but when they saw Tanjiro standing still, they suddenly became flustered.

Anyone could see that Kokushibo was currently in his weakest state. If they were Tanjiro Kamado, they would definitely choose to attack under such circumstances.

The fact that Tanjiro Kamado is not making any move now is most likely because he has exhausted his strength.

Come to think of it, given the intensity of the attack just now, it's clear how much power Tanjiro Kamado was able to withstand for so long, even managing to blast off half of his opponent's head.

Tanjiro Kamado's exhaustion actually made it easier for them to accept.

But all of this is predicated on Tanjiro Kamado not being in a battle with Kokushibo.

Even Sanemi Shinazugawa was considering abandoning the demon before him and launching an attack on Kokushibo, but Gyomei Himejima, who had no eyes, slowly spoke:

"Wait, now is not the time to make a move."

"If we don't act now, when will we?"

Sanemi Shinazugawa paused, and then, realizing he had lost his composure, easily deflected the attack from the demon beside him with a swift swing of his sword.

Although these demons, infused with Muzan Kibutsuji's blood, have gained the fighting power of the previous Upper Moon demons, the current Sanemi Shinazugawa is no longer the same Sanemi Shinazugawa.

Having received Tanjiro Kamado's gift of the Seed of Love, he had raised his strength to a much higher level. Therefore, he now felt quite relaxed dealing with these Upper Moon demons, who were previously quite troublesome.

He had the evil spirit he was facing firmly under his control, but it seemed to lose focus after hearing the voice of Himejima Gyoumei.

"Although I can't see clearly, I noticed that Tanjiro Kamado's heart rate hasn't increased at all. Perhaps the so-called fatigue is just an illusion."

Himejima Gyomei was also using his peculiar weapon to suppress the evil spirit opposite him, and several times he almost slashed the evil spirit's neck.

"Furthermore, with Akaza protecting you now, it will be very difficult for you to succeed."

"Beimingyu Xingming spoke up."

"Illusion?"

Sanemi Shinazugawa was taken aback; he hadn't considered that possibility.

But thinking about it, it makes sense. Tanjiro Kamado always seemed so calm and collected, and he had never seen his opponent look exhausted.

Of course, the most important thing is the sentence following Himejima Gyomei's statement: he is indeed no match for Akaza now; if he goes now, he will only get beaten up.

There may be other possibilities.

However, he was still somewhat unwilling, and with a swing of his sword, he severed the arm of the demon before him, saying:

"Are we just supposed to watch?"

"Now we can only trust Tanjiro Kamado. Our priority is to clear out these demons scattered throughout headquarters, and then we can figure out a way to help Tanjiro Kamado."

With a swift movement, Beimingyu Xingming severed the neck of the demon before him and quickly turned his attention to another demon.
