Mountain Child

One month later, Demon Slayer Corps headquarters.

Ubuyashiki Kagaya arrived at Kujo Tachibana's estate, accompanied by Tamayo.

Seeing the "duo" arrive, Kujo Tachibana paused for a moment before breaking into a smile.

He looked toward Tamayo and asked:

"Is it finished? The serum to suppress their cellular division?"

Tamayo nodded and produced two vials, one black and one red.

"The red one is tailored for Kibutsuji Muzan, and the black one is prepared for Kokushibo. While I'm not certain if Kokushibo, as a Demon King, possesses that specific trait, it's better to be safe than sorry!"

These two vials were custom-made by Tamayo, utilizing the Demon King blood extracted from the bodies of demons and the Martial Demon.

Kujo Tachibana took the glass vials and asked: "How do I use them? Injection?"

Tamayo explained in detail:

"If you are certain you will use them within half an hour, you can draw the serum into a syringe beforehand, or simply allow the liquid to make contact with their wounds to achieve the effect."

After saying this, Tamayo hesitated for a moment before asking:

"Kujo-san, are you truly confident that you can face Kibutsuji Muzan and Kokushibo simultaneously?"

Hearing this, Kujo Tachibana rubbed his chin in thought, recalling the details of the Infinity Castle battle from the manga.

After a moment, Kujo Tachibana looked at the "duo" with a serious expression and promised:

"If Kibutsuji Muzan takes the bait regarding the Blue Spider Lily, he will certainly die!"

"Of course, the same goes for Kokushibo."

"However, as for the specific planning of this matter, I must rely on you, Master."

Kujo Tachibana had already informed Ubuyashiki Kagaya about the Blue Spider Lily during his last return.

Although Kujo Tachibana did not explain the exact source of this information, Ubuyashiki Kagaya trusted him and did not press for further details.

A few days after they returned to headquarters, the vines Kujo Tachibana had brought back bloomed with over a dozen blue flowers in broad daylight.

Fortunately, Tamayo used a special solution to preserve the flowers intact, though it was unclear how much of their medicinal potency remained.

Regardless of how much potency was left, Kujo Tachibana would not give Kibutsuji Muzan or Kokushibo the chance to experience it.

Ubuyashiki Kagaya nodded. Once the "Blue Spider Lily," which Kibutsuji Muzan had sought for a thousand years, appeared, he was certain neither Demon King would remain indifferent!

After all, this flower could allow them to take a step further and overcome their only weakness: sunlight!

Moreover, the Demon Slayer Corps should currently pose no threat to these two Demon Kings, provided Kujo Tachibana's true strength remained unexposed.

This was a trap laid in plain sight!

This Blue Spider Lily was something Kibutsuji Muzan and Kokushibo would fight to the death to obtain!

There might only be one flower, but there were two Demon Kings.

Would Kibutsuji Muzan yield?

Or would Kokushibo display a spirit of contribution and leave the opportunity to the other?

Thinking of the cursed fate of the Ubuyashiki family that had lasted for a millennium and was about to be ended by his own hand, Ubuyashiki Kagaya could not suppress the excitement manifesting on his face.

Having witnessed Kujo Tachibana's strength, which far exceeded his imagination, there had never been a moment where Ubuyashiki Kagaya believed so firmly.

Three days later, on the outskirts of Kumagaya County.

Kujo Tachibana, Ubuyashiki Kagaya, and the Hashira of the Demon Slayer Corps all gathered within a vast, empty canyon.

This was the site chosen by Ubuyashiki Kagaya for the decisive battle!

Everyone carefully observed the environment within the canyon.

They then shared their own opinions and offered various suggestions.

For instance, placing giant boulders on the cliffs at both ends of the canyon, setting traps at the bottom, and so on.

Following this, they spent over ten days modifying the canyon.

The plan targeting the two Demon Kings finally began in earnest!

"Mountain Child" was a demon transformed by Kibutsuji Muzan who had lived for over a hundred years, but being timid and cautious by nature, he had never entered a large human city.

Just as his name suggested, he had lived in these deep mountains for years.

His "food" consisted of the hunters and farmers who entered these woods.

In the first few decades, these humans would occasionally gather to resist him.

The largest instance involved over a hundred men from more than ten villages surrounding these mountains, who gathered with bows, long swords, and even farm tools, charging up the mountain just like that.

However, the gap between ordinary people and demons could not be bridged by a mere hundred or so lives.

In the eyes of these people, the speed of the Mountain Child was like a phantom; his strength could shatter a boulder with a single punch, and a body that could heal wounds in an instant only drove this group of ignorant villagers to despair.

Yet, the Mountain Child did not kill all these men, not out of "mercy," but simply because he did not want to waste food.

If he killed them all at once, he wouldn't be able to finish eating them, and leaving them there would only lead to rot. It didn't matter if he let them go; in order to survive and not starve to death, these humans would have no choice but to enter this mountain forest again!

After letting those men go, it seemed as if these humans had developed some sort of misunderstanding about him...

Not only did they never resist him again, but every so often, they would take the initiative to deliver several human children to the entrance of the cave where he resided.

To this day, this situation has been maintained for over eighty years.

However, the Mountain Child, who had turned low-profile caution into an instinct, ultimately could not escape the gaze of Muzan.

After the Lower Rank Demon members of the Twelve Kizuki died one after another, before Muzan could even re-establish the Lower Rank Demon ranks, Kokushibo set up his own faction and transformed one powerful Martial Demon after another!

Facing the pressure brought by Kokushibo, Muzan certainly could not act as he had before, casually grabbing a few demons to fill the positions of the Lower Rank Demon.

This time, through the blood he had left behind, Muzan sensed the six strongest demons.

He then summoned them into the Infinity Castle and provided these six demons with blood once more.

In the end, the four demons who survived the infusion of Muzan's blood were promoted to the Lower Rank Demon of the Twelve Kizuki.

The Mountain Child was one of those lucky ones, and he was now the Lower Rank Three of the Twelve Kizuki—Mountain Child.

And today was the weekly feeding time for Lord Mountain Child.

The Mountain Child strode on his short, thick legs, swaying as he walked toward the exit of the cave.

But as the Mountain Child stepped out of the cave, he felt a bit puzzled.

Looking at the middle-aged man standing before him with a faint scar on his forehead.

The Mountain Child wondered in his heart:

Are those humans really so bold? They actually dare to change Lord Mountain Child's menu without permission!

To think they actually sent over a man with such dry, tough meat today!

However, the Mountain Child thought about it; having eaten children for over eighty years, changing the flavor occasionally didn't seem like such a bad idea...
