To Treat the Plague, Conceptually Erasing Giyu Tomioka, Tanjiro, and Sabito's Souls!

A Net of Heaven member dressed in black skintight clothing said to Black-and-White Xuan Jian, "No one can keep a secret from Net of Heaven!"

"Give me an hour, and I'll make him spit out everything we want to know!"

Black-and-White Xuan Jian, holding the Black-and-White Twin Blades, nodded at that. Then he raised his head and looked toward the slowly rising sun. His eyes were devoid of joy or sorrow...

No one knew what he was thinking.

All around them lay dozens of Demon Slayer Corps members' corpses!

Like Cipher Pol Aigis Zero, Net of Heaven had also refrained from starting a livestream on Zhao Gao's orders. They had likewise chosen to send the information back to Qin's Moon World through private messages!

Besides Cipher Pol Aigis Zero and Net of Heaven, a group of ninjas with cracked faces and thousands of White Zetsu appeared deep in the mountains.

There were also hundreds of thousands of desperadoes from various worlds who had appeared in the Demon Slayer World.

And these were only the vanguard.

Countless opportunists were still on their way, hoping to turn the tables by investigating the Demon Slayer World.

At this moment, the entire Demon Slayer World had completely descended into madness!

Apart from a few organized teams, all these opportunists started livestreams to showcase their journeys of exploring the Demon Slayer World to the Myriad Worlds.

Of course, the livestream with the largest audience...

Was still the [SCP Foundation]'s livestream. Whether in viewer count or quality, it was on an entirely different level from the other livestreams.

At that moment, every viewer in the [SCP Foundation] livestream was staring intently at SCP-049, the Plague Doctor, on-screen, wanting to see whether it would attack Tanjiro and Nezuko!

But the scene that followed left them utterly bewildered.

In their imagination, SCP-049, the Plague Doctor, should have killed Tanjiro and Nezuko outright, then turned them into Zombies.

Yet SCP-049, the Plague Doctor, began examining Nezuko's injuries like an ordinary doctor.

As he examined her, he asked Tanjiro, "Young man, how did your sister get injured?"

"From the wound, it doesn't look like it was caused by a beast!"

"It looks more like she was bitten by a 'person'!"

Tanjiro watched SCP-049, the Plague Doctor, skillfully examine Nezuko's wound. Moreover, he truly sensed no hostility from this strangely dressed man.

The vigilance in his heart gradually faded by more than half.

Upon hearing SCP-049's question, he immediately said, "I don't know either!"

"Yesterday, I went to town to sell charcoal. Since the heavy snow had blocked the mountain roads, I stayed beneath a large tree at the foot of the mountain. When I returned home, I saw..."

"I saw my mother and the others lying in pools of blood!"

"Nezuko was the only one still breathing."

"That's why I carried Nezuko and ran toward town. Then I met you!"

At this point, Tanjiro took a deep breath and asked tremblingly, "Doctor, can my sister still be saved?"

"She's the only family I have left."

"I..."

As SCP-049, the Plague Doctor, listened to Tanjiro's account and examined Nezuko's injuries, he said calmly, "Don't worry. As long as I'm here, there's no patient I can't save."

"Especially one in such..."

Tanjiro was overjoyed when he heard this and hurriedly said, "Doctor, as long as you save Nezuko—"

"No matter how much money it costs—"

"I'll..."

But before Tanjiro could finish, he suddenly smelled an intense hostility in the air. It was so powerful and so cold that—

Tanjiro couldn't even finish speaking. Overcome by fear, he stood rooted to the spot.

He even found it incredibly difficult to breathe.

What terrified Tanjiro even more was that this overwhelming killing intent was actually radiating from the beaked doctor who had just been gently asking about Nezuko's injuries.

He couldn't understand why the beaked doctor had suddenly developed such intense killing intent toward him and Nezuko.

He hadn't offended him, had he?

Unknown to Tanjiro, he wasn't the only one affected. Even the viewers in the livestream inexplicably felt a wave of terror.

That horror from the depths of their souls reminded them of the fear of being dominated by SCP-173, Little Peanut, and SCP-096, the Shy Guy!

Under Tanjiro's bewildered gaze, SCP-049, the Plague Doctor, looked at Nezuko and roared furiously, "The plague! You have the plague!"

"Heh heh..."

"You hid it very well! You nearly fooled me! Every plague must be treated!"

"It must... be treated!"

As he spoke, SCP-049, the Plague Doctor, extended his slightly withered fingers toward Nezuko, who had fallen unconscious from her severe injuries.

He intended to conceptually take Nezuko's life, thereby treating the plague.

Just then, accompanied by a dazzling flash of sword light, the Water Hashira, Giyu Tomioka, dressed in the Demon Slayer Corps uniform, appeared at the perfect moment. While saving Nezuko...

He also used his Water Breathing to free Tanjiro from his fear and restore control of his body!

Chapter Thirty-Seven: To Treat the Plague, Conceptually Erasing Giyu Tomioka, Tanjiro, and Sabito's Souls!

SCP-049, the Plague Doctor, looked at the Water Hashira, Giyu Tomioka, who stood in his way, and said in an extremely hoarse voice, "You have the plague too!"

"You all have the plague!"

"You nearly escaped my detection! You must accept treatment!"

Hearing SCP-049's words, Tanjiro, who had regained the ability to move, couldn't help shouting at him, "We don't have the plague!"

"My sister is only injured!"

"It isn't the plague!"

As Tanjiro spoke, he tried to take Nezuko from Giyu Tomioka and bring her to the town at the foot of the mountain for treatment.

Although he knew that after this delay...

Nezuko was probably in grave danger.

But as long as there was even the slightest hope, he didn't want to give up. Nezuko was his last remaining family in this world.

However, he was stunned to discover that the swordsman who had suddenly appeared was actually stopping him.

Of course, that wasn't the most important thing.

The most important thing was that Nezuko, who had been nearly out of breath, suddenly began struggling violently. Seeing this, Tanjiro was filled with wild joy.

But before he could say anything, he saw that Nezuko had somehow grown sharp fangs.

Her formerly clear eyes had also turned blood-red.

She let out unintelligible whimpers, as if, without Giyu Tomioka restraining her, she would swallow him whole the next moment.

Seeing Nezuko in this state, Tanjiro couldn't help recalling the legend his grandfather had told him at the foot of the mountain the previous night!

Nezuko had actually become a Demon!

No!

Nezuko couldn't become a Demon!

As Giyu Tomioka restrained the Demonized Nezuko, he said to SCP-049, the Plague Doctor, "You can tell that she's about to become a Demon too?"

"Is the plague you mentioned Demonization?"

Giyu Tomioka looked at SCP-049, the Plague Doctor. Although the man's clothing was strange and gave him an unprecedented sense of dread—

He truly wasn't a Demon!

Therefore, Giyu Tomioka couldn't help thinking that the plague this strangely dressed man referred to was Demonization!

"Demonization? No! That isn't the plague!"

Although SCP-049, the Plague Doctor, was already furious, he still explained, "The plague refers to natural disasters! Mass extinction..."

"Ah, I don't even know how to explain it to you!"

SCP-049 seemed unable to think of suitable wording. In the end, he hammered his temples and said, "But I know that I must find a way to perfectly treat the plague!"

"Although many people have already chosen to submit, I absolutely will not! It is my duty to free the world from the plague. I must find a treatment that will end everything."

"Of course, before that, I must eliminate all carriers of the plague!"

"And you are carriers of the plague!"

As he spoke, SCP-049, the Plague Doctor, walked toward Giyu Tomioka. Although he appeared to be moving slowly, he reached Giyu in the blink of an eye.

Then he extended his withered finger and pointed it toward Giyu Tomioka.

Giyu Tomioka was the Water Hashira!

He could be described as a veteran of countless battles. The instant SCP-049, the Plague Doctor, attacked, he felt tremendous pressure.

His decades of combat experience kept warning him.

Although the opponent wasn't a Demon—

His combat power was even more frightening than a Demon's. If he didn't go all out, he would surely die here.

Thus, Giyu Tomioka didn't hesitate and immediately used his Water Breathing, attempting to kill SCP-049, the Plague Doctor, in one strike!

"Water Breathing: Eleventh Form—Dead Calm!"

As Giyu Tomioka's voice rang out, a pale-blue domain appeared around him from thin air. Everything within the domain came to a standstill.

Then streams of water condensed into blades and slashed toward SCP-049, the Plague Doctor's approaching withered body.

Water Breathing: Eleventh Form—Dead Calm was Giyu Tomioka's self-created ultimate technique.

It not only allowed him to enter a state of tranquil stillness.

Within the domain, it could also nullify any "technique." This was Giyu Tomioka's strongest killing move.

He was confident that even if SCP-049, the Plague Doctor, possessed power comparable to an Upper-Rank Demon, it would still be wounded by this technique.

But the scene that followed left Giyu Tomioka completely stunned.

The water blades, each powerful enough to injure an Upper-Rank Demon, struck SCP-049, the Plague Doctor. Yet they not only failed to kill it—even its clothes weren't torn.

Not to mention stopping its advance.

Otherwise, it would be too late.

Seeing this, Giyu Tomioka knew that the gap between himself and SCP-049 was far too great. His only chance to survive was to run.

But before he could escape—

A finger appeared in his vision. It slowly grew larger before landing against the center of his brow.

Giyu Tomioka's vision immediately went black, and he sank completely into eternal darkness.

After killing Giyu Tomioka, SCP-049, the Plague Doctor, didn't hesitate. He extended his hand and pointed toward the bewildered Tanjiro and the already Demonized Nezuko.

Tanjiro wanted to dodge, but even Giyu Tomioka had been unable to evade the attack.

How could Tanjiro possibly dodge it?

He could only watch helplessly as SCP-049, the Plague Doctor's withered finger, landed on his brow. Then both Tanjiro and the already Demonized Nezuko—

Fell completely silent!

Just as everyone in the livestream thought the matter was over, two translucent souls emerged from the corpses of Giyu Tomioka and Tanjiro...
