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

Kibutsuji Muzan sensed Kokushibo's thoughts and couldn't help but feel somewhat satisfied.

It must be said that Kokushibo, who is always striving towards a goal, is relatively easy to manipulate.

Of course, if the other party has other ideas, he will naturally take action.

Thinking of this, he no longer hesitated and immediately stretched out his hand. In the next instant, the skin of his palm surged and transformed into terrifying fleshy tentacles, which directly pierced into the bodies of Kokushibo and Akaza.

Blood was injected into Kokushibo and Akaza's bodies again, and this time the transfusion lasted many times longer than the last one.

Gradually, both Kokushibo and Akaza's bodies underwent tremendous mutations, and they were no longer recognizable as human, instead becoming huge fleshy tumors and blood cocoons.

From within the two blood cocoons came low growls, filled with boundless pain.

At this point, Muzan Kibutsuji stopped transfusing blood, knowing that the two people's bodies had reached their critical point.

"Narika, open the door and let me see the others."

Ghost Dance Tsuji Muzan gave the order.

He naturally understood the principle that you can't put all your eggs in one cage.

Therefore, he did not place his hopes solely on Kokushibo and Akaza.

After all, we should prepare for the worst.

If it might take Kokushibo and Akaza together to hold off Tanjiro Kamado, then the rest of the Demon Slayer Corps would naturally need someone to hold them off.

At this point, other ghosts can come into play.

Therefore, he wants to enhance all the ghosts.

When all the demons have become stronger, it will naturally be time to attack the Demon Slayer Corps.

Boom boom boom!

Inside the Infinity Castle, countless demons entered and were then unleashed before Muzan Kibutsuji through various portals.

Countless demons were brutally amplified by Muzan Kibutsuji.

Muzan Kibutsuji's target was these demons, at least those at the level of Pillar-level swordsmen, so that they could be put to use.

He didn't have high hopes for these evil spirits, thinking that he could win by sheer numbers.

Having a dozen or so that can be put to use would be enough.

Suddenly, the Infinite City was no longer so empty, but was filled with a mixture of various sounds.

There were sounds of pain, screams, or howls of joy, which seemed to have turned the entire Infinite City into a true city of demons.

Meanwhile, the Demon Slayer Corps was unaware of what was happening inside the Mugen Castle, but as Lin Yu had previously set out, the entire Demon Slayer Corps was already in operation again.

This was all in preparation for the possibility of Muzan Kibutsuji's imminent arrival.

Based on what he had learned about Muzan Kibutsuji from Lin Yu and Tamayo over the past few days, Kagaya Ubuyashiki guessed that with someone like Tanjiro Kamado around, if Muzan Kibutsuji still wanted to take Nezuko, then the latter would definitely use all his power.

Given the recent disappearance of the demons, he vaguely realized that Muzan Kibutsuji had most likely gathered the demons together in one place.

Therefore, his current strategy cannot focus solely on Muzan Kibutsuji and those Upper Moon demons.

They also need to face other evil spirits.

So the entire Demon Slayer Corps started operating again, with everyone who had fighting ability grouped together, while those without fighting ability were sent out.

Some of the Pillar-level swordsmen joined forces with Tanjiro Kamado to launch the main attack, while others protected Kagaya Ubuyashiki and Nezuko.

There are also some plans that can weaken Muzan Kibutsuji in advance.

In any case, Kagaya Ubuyashiki had staked everything on it.

After all, Lin Yu had said from the beginning that now might be the best time to kill Muzan Kibutsuji.

With the opportunity to fulfill his family's centuries-old dream right before him, how could Ubuyashiki Kagaya not cherish it?

Therefore, in recent days, the Pillar-level swordsman and several others have begun to frequently visit Kagaya Ubuyashiki's residence.

Kagaya Ubuyashiki only slept for one or two hours each night.

Ubuyashiki Amane had tried to persuade him several times, but she still couldn't change Ubuyashiki Kagaya's mind.

Meanwhile, Tanjiro Kamado has stopped using the medicine and has begun to continuously refine his physical body.

He threw punches repeatedly, circulating his internal energy while simultaneously adjusting his physical condition to its most perfect state. (End of Chapter)

Chapter 288 Hundred Ghosts Night Parade

For several days in a row, the sky was overcast, creating an indescribable oppressive and somber atmosphere.

The rain is coming and the wind is all over the building.

One night, a member of the Demon Slayer Corps who had cleaned up the ruins of the Butterfly Mansion was patrolling when he mentioned that he had met Tanjiro Kamado.

Although his companions had heard Tanjiro Kamado say it many times before, they still found it endlessly fascinating.

After all, everyone was curious about what a legendary swordsman like Tanjiro Kamado looked like.

However, they had always heard that Tanjiro Kamado seemed to be training every day and almost never appeared in anyone's sight.

Therefore, the chances of actually seeing Tanjiro Kamado are extremely rare, and all they can do is hear from those who do see him describe what he looks like.

"I was cleaning up the battlefield at the time, and let me tell you, it was really scary. The entire ground was destroyed, and countless ruins were directly embedded in the surrounding intact walls."

The man spoke with great enthusiasm, "While I was still marveling at it, I saw Lord Kamado suddenly walk back from afar. Let me tell you, apart from some bloodstains on Lord Kamado's body, he wasn't injured at all, not even his clothes were torn. It's clear that Lord Kamado and those Upper Moon demons weren't hurt at all; they must have dealt with them easily..."

Before he could finish speaking, someone suddenly reached out and grabbed his hand, trying to pull him back.

Unexpectedly, a cold glint flashed, and the heads of the three patrolmen flew into the air. Then, several dark figures rushed up like hungry ghosts and snatched the heads off the three men. Afterward, more than a dozen dark figures rushed up and devoured the remaining three corpses.

"They're quite alert, but unfortunately they're too slow."

A terrifying face with three pairs of eyes stepped into the moonlight.

It was Kokushibo.

However, Kokushibo now looked somewhat different from before.

One change was that his physique had become stronger, and the other was that his previously unstable eyes were now truly covered with eyes on his neck, constantly staring into the distance.

At the same time, several blades also grew out at the joints.

Behind him, countless dark figures surged, emitting snickers and swallowing sounds. They could smell the fresh flesh and blood from the pile of buildings before them, especially the bloody stench of the recently devoured corpses, which still lingered in the air, fueling their increasingly violent impulses.

Every now and then, the sounds of chewing, teeth grinding, and swallowing saliva could be heard in the air.

"let's go."

"Kuroshibo said calmly."

Instantly, all the shadowy figures moved and surged towards the Demon Slayer Corps headquarters.

It was eerie and filled with the howling of ghosts and wolves.

On the other side of the Demon Slayer Corps headquarters, Akaga stood on a cliff, surrounded by mangled flesh and Demon Slayer Corps uniforms, clearly indicating that a patrol team had also died at his hands.

"It seems that Kokushibo's side has already started making moves, but it also seems that the humans were prepared all along. Perhaps they were waiting for us?"

Akaza clenched his fist as he said this.

"Okay, very good. I won't let that experience happen again."

He had been holding back a lot of anger, which he had previously suppressed because of the frustration of his defeat against Tanjiro Kamado. But after becoming stronger twice in a row, this anger had finally risen to the surface.

This time, he is determined to join forces with Kokushibo to kill the one who has frustrated him!

"let's start."

At Akaza's command, the demons behind him, who had been unable to restrain themselves any longer, poured out in droves.

On this day, a hundred ghosts paraded through the night, their numbers exceeding one hundred.

A few minutes later, the entire Demon Slayer Corps headquarters area resounded with shouts of battle, and fireworks lit up the sky.

The demons have already started fighting against the Demon Slayer Corps headquarters.

Moreover, if the members of the Demon Slayer Corps headquarters hadn't been in small groups and hadn't undergone rigorous training over the past two months, they wouldn't have been able to withstand the attacks of these demons.

After all, these demons are all at least some level of Pillar-level strength.

The Demon Slayer Corps members were forced into retreat.

However, in some places, some evil spirits still suffered a setback.

Without exception, the Pillar-level swordsmen appeared in every place.

Akaza also noticed that these Pillar-level swordsmen seemed to be stronger than before, faster and more powerful.

At the same time, each swing of the sword left a faint trace in the air.

It took half a day for the crowd to slowly disperse.

Akaza's eyes narrowed slightly as he realized that these people had actually become much stronger.

"Could that power be the strange power that Kokushibo mentioned about Tanjiro Kamado?"

Akaza observed closely, but still couldn't find a clue.

However, seeing his demons being slaughtered by these Pillar-level swordsmen, Akaza no longer hesitated and took a step forward.
