Chapter 254: Infinity Castle

Unacceptable!

Unforgivable!

Fake, fake, fake!

Muzan Kibutsuji finally understood why that man had been so calm and composed. It wasn't because of the explosion. It was because the blue spider lily had been fake from the very beginning!

Rage!

Unparalleled rage!

Muzan Kibutsuji had never felt such hatred before. In his eyes, the Demon Slayer Corps was nothing more than a mosquito, something he could crush with a single slap. But now, this mosquito dared to suck his blood?!

"I will kill all of you!!!"

He resolutely decided that in the coming days, he would exterminate every single member of the Demon Slayer Corps.

The moon in the sky was obscured by clouds, plunging the world into darkness. The wind picked up, rustling through the trees, creating an eerie, spine-chilling atmosphere.

Muzan Kibutsuji could sense that the Hashira were not far from him now. They would likely arrive just as he finished healing himself.

Ah, he could already picture the deaths of those Hashira…

"!?"

In an instant.

A flash of blade light silently appeared before him.

When?!

He hadn't sensed the presence of this blade's wielder at all. It was as if they were a ghost, completely devoid of any detectable aura!

Wait, this is—!

Sun Breathing!!!

Hadn't this guy already died in the explosion?!

In the light of the blade, Muzan Kibutsuji caught a glimpse of the attacker's face.

It was the same face he had just seen moments ago. But now, it was flushed with vitality, completely devoid of the previous pallor.

This wasn't the time to wonder how this guy was still alive.

The real question was how to deal with this Sun Breathing.

"Nakime!"

Suddenly, the ground beneath his feet transformed into the roof of a building. In that brief moment, space itself had shifted.

Muzan Kibutsuji was still in front of Li Mo, but the Demon King now looked utterly disheveled.

The sudden change in environment caused Li Mo's attack to hesitate for a split second, but he quickly adjusted his breathing and stance. The momentum of his Sun Breathing Thirteenth Form remained unbroken.

At full power, Li Mo revealed his true form. Snow-white ears appeared atop his head, and two pristine tails swayed behind him.

The blade had already made contact with Muzan Kibutsuji's flesh. The angle of the Sun Breathing Thirteenth Form perfectly aligned with the scar left by that swordsman years ago, dealing another devastating blow to Muzan Kibutsuji.

But just as the ground beneath him had shifted, Muzan Kibutsuji seemed to have mastered the ability to teleport, disappearing from Li Mo's sight before he could deliver the final blow.

"Nakime?"

Li Mo searched his memory for the name Muzan had called out. The image of a long-haired woman appeared in his mind. She seemed to possess the ability to control the Infinite Fortress, capable of pulling any demon from afar into its depths.

—A spatial ability.

He recalled the former Upper Moon he had slain upon his debut, who also had a noble spatial ability. Unfortunately, this Nakime seemed to be a superior version of that demon.

Perhaps that was why she had become the former Upper Moon.

"Let me tell you something—I'm not just here to spy!"

Standing on the rooftop, Li Mo could clearly feel the prying eyes from all directions. With a single glance, he spotted the same eyeball-like monsters he had seen in the area days before.

Li Mo didn't particularly like these creatures. He gathered his magical energy and fired off magical bullets, exploding each of the eyeball monsters one by one until there were no more prying eyes around him.

He gazed at the moon in the sky. His senses told him that the other Hashira had also arrived at the battlefield and had been pulled into this Infinite Fortress.

He could feel that there were countless demons within this fortress. Just a glance at the sheer number of health bars was enough to give anyone a headache. It wasn't that their health was high, but the sheer quantity was overwhelming.

If he had to cut them all down one by one, how long would it take? By the time he finished, his Nichirin Blade would probably be broken.

Li Mo was now wielding a Nichirin Blade, not the Tsubame Gaeshi. In terms of quality, the Tsubame Gaeshi was far superior to the Nichirin Blade. But given the Nichirin Blade's special effectiveness against demons, the swordsmiths had begun crafting a blade specifically for Li Mo after he returned to the Demon Slayer Corps.

—The location of the swordsmiths had not been leaked yet. They hadn't been attacked, and the place remained safe. If nothing went wrong, Amane and the children should be there.

As for the Master, he would be nearby, providing support.

"Ah, found him."

Closing his eyes, Li Mo searched for Muzan Kibutsuji's current location. Along with the explosives and cross-shaped nails, Li Mo had also placed talismans around the Ubuyashiki estate. While the talismans would be destroyed by the high temperatures of the explosion, their effects would spread at the moment of destruction.

—Yes, it was a tracking spell.

"Muzan Kibutsuji's recovery isn't slow. Before the attack, I used the wind to deliver a portion of poison into his body. But with his regenerative abilities, he should recover soon."

A flash of the blade, and Li Mo casually decapitated a demon that had climbed onto the rooftop. He began to move.

Earlier, Tamayo had developed a poison that slowed a demon's cell division, and another that accelerated aging. Combined, these poisons could weaken Muzan Kibutsuji. Of course, these were backup measures. The first poison Muzan would notice would be the one inhibiting his regeneration.

The dosage wasn't enough, so he needed to act quickly.

But before going after Muzan, there was one more thing to deal with… Nakime, right? Her spatial teleportation ability was indeed troublesome. Even if he found Muzan Kibutsuji, she could just teleport him away again.

Spatial abilities were truly annoying. Why could Blood Demon Arts develop spatial powers? It was baffling.

What exactly were demons?

What had that physician done to Muzan Kibutsuji a thousand years ago to turn him into what he was now?

Unfortunately, Li Mo couldn't travel back to the Heian era to witness the process.

His thoughts came to an abrupt halt. Li Mo decisively focused on the task at hand. Even though he knew Muzan Kibutsuji's location, his first priority was to kill Nakime, the one who could manipulate space.

Within the Infinite Fortress, there were many of Nakime's eyeballs moving about. Li Mo used the connection between these eyeballs and her true body to locate her. However, the entire fortress was under her surveillance.

An illusory shadow emerged, heading toward Muzan Kibutsuji. Meanwhile, the real Li Mo slipped into the shadows, moving toward Nakime.

If every demon had a unique Blood Demon Art, then Li Mo, who had mastered both magic and Onmyōdō, could be considered a being with multiple Blood Demon Arts.

Yōkai walk in the shadows.

On another battlefield, the Demon Slayer Corps swordsmen, guided by their Master and led by the Hashira, charged into the city.
