Demon Slayer: I am a Demon.

…………

After Kanzaki Aoi left, Su Mu looked at Tamayo and Yushiro.

Are you a ghost?

Yushiro could not hide his shock; he sensed the presence of a kindred spirit in Su Mu.

Have you ever seen a ghost bathed in sunlight?

Su Mu raised his eyes and gave a calm reply.

Yushiro was speechless. No demon could bask in the sunlight, not even Muzan Kibutsuji. Su Mu had just walked in from the sunlight.

This is something that ghosts absolutely cannot do.

"It's strange, I can sense the aura of a ghost from you."

Zhu Shi invited Su Mu to sit down, and then brought over a cup of tea.

"I'm not entirely sure either. Many ghosts say the same thing, that they can sense a ghostly aura in me. But unfortunately, I am completely different from those pathetic creatures controlled by their own desires."

Yushiro's expression turned somewhat awkward.

Tamayo remained calm, though her eyes were slightly lowered, as if she were thinking about the unacceptable things she had done because she had failed to control her desires.

Su Mu had already picked up his teacup and started sipping his tea.

"I wonder what brings you here, sir?"

Tamayo knelt beside her and spoke gently at that moment.

"I've heard that Miss Tamayo was once Muzan Kibutsuji's close attendant, and I'd like to learn more about Muzan Kibutsuji."

"That ghost!"

Tamayo spoke in a low voice, which was calm and soft, but it revealed a deep-seated hatred.

Tamayo naturally had a deep understanding of Muzan Kibutsuji. After all, she had once been Muzan's close attendant, and as a doctor, she had participated in Muzan's research on how to overcome sunlight. She had also personally witnessed the battle between Yoriichi Tsugikuni and Muzan...

Through Tamayo's narration, Su Mu gained a deeper understanding of the demon Muzan Kibutsuji.

Without a doubt, Muzan is an extremely contradictory individual, both cruel and ruthless, yet also extremely cowardly and weak. He has a deep-seated fear of death, is averse to others mentioning 'serious illness' or 'not long for life,' and has an obsessive desire for immortality.

As the Demon King, Muzan achieves absolute control over all demons through the 'blood curse'. He can not only read the thoughts of his subordinates and sense their location, but also instantly disintegrate the bodies of demons who reveal his information through the curse. He can also communicate telepathically with demons at close range and share his vision.

In terms of abilities, Muzan's power is not a single-dimensional strength, but a complete system built around 'immortality and domination', possessing five brains, seven hearts, and a body core that can move freely...

Furthermore, Muzan Kibutsuji broke through the limits of demons very early on. Ordinary demons would die instantly if beheaded by a Nichirin Blade, but Muzan Kibutsuji would not. This was proven in his battle with Yoriichi Tsugikuni. Even after being cut into 1,500 pieces by Yoriichi Tsugikuni, he was still able to escape, still possessing the 'Crimson Blade,' an attack that is extremely effective against demon regeneration.

"Even if it splits into 1,800 fragments, each fragment can still survive independently. Even if most of the fragments are destroyed, as long as only one fragment remains, it can be completely restored."

……

After telling all this, Tamayo's eyes dimmed, and even showed some despair. Was there any possibility of destroying such a powerful demon?

Perhaps, there was once an opportunity, during the Warring States period, when that man had a chance to completely kill Muzan Kibutsuji.

But since the departure of the original swordsman who used the Breath of the Sun, such an opportunity has been completely lost.

"It seems very difficult to kill Muzan Kibutsuji unless he is completely exposed to the light of day. But given Muzan Kibutsuji's ability to escape, it is almost impossible unless his ability to escape is restricted."

Su Mu sighed.

"I've been doing research on this, trying to limit that ghost's ability to escape..."

Tamayo said softly, "I've been researching lately how to turn demons into humans. When a demon that is almost immortal becomes human, it is no longer an immortal being and will have more weaknesses."

"We also study various cells, and have already developed drugs that can make cells age at a rate of almost fifty years per minute. We are also continuously researching how to stop cells from dividing..."

Su Mu nodded, this was just like his memory of the final battle, where Tamayo played the best MVP role of the entire match.

To this day, Tamayo has even developed finished products of these medicines.

"Such a potion would not only be effective against Muzan Kibutsuji, but also against other demons, right?"

Su Mu inquired.

"It will naturally have an effect."

Tamayo nodded: "These potions, when injected into any demon, can instantly weaken it to an extremely frail state. Even the Twelve Demon Moons, if injected with these potions, will instantly lose strength to the level of an ordinary demon."

"Why doesn't Miss Tamayo give these medicines to the Demon Slayer Corps?"

Su Mu's face showed curiosity. If the Demon Slayer Corps mastered these potions, even ordinary swordsmen would have the ability to fight against the Twelve Demon Moons, and even Upper Rank Demons might be able to be dealt with.

"I would never use these potions to deal with ordinary ghosts."

Tamayo shook her head without hesitation: "These potions only have one chance, one chance against that demon. That demon has a very strong ability to decompose things. I suspect that given some time, that demon can completely neutralize these potions. Once neutralized, using such potions again will have no effect..."

"I see."

Su Mu also understood why, despite Tamayo's long-standing communication and cooperation with the Demon Slayer Corps, her research findings had never appeared within the Demon Slayer Corps.

After all, such a potion only has one chance. If it fails, the potion will be useless. Especially if the cautious Muzan Kibutsuji finds out, there will be no chance at all.

"So far, these drugs are still in the early stages, and there are still many areas where research is ongoing."

Tamayo sighed. So far, she had not completely developed a drug that could turn demons into humans, but she had already developed a drug that showed this trend.

"Could we add the toxin from wisteria, which can kill ghosts?"

Su Mu asked again.

“I obtained this medicine from Kagaya Ubuyashiki. It’s a very powerful medicine, even effective against the Twelve Demon Moons. But the medicine I’m researching turns demons into humans. If it turns demons into humans, then the toxin that kills them doesn’t seem to be very effective…”

When talking about wisteria flower toxin, Tamayo's face was full of admiration, and she carefully analyzed the various results that this toxin would produce when combined with her research.

"I actually really wanted to have a proper discussion with 'Rin,' but she seems to dislike me..."

Tamayo sighed. She felt that Shinobu Kocho's medical skills were very strong, and if the two of them studied together, perhaps there would be good results.

“I will convince her on this point.”

Su Mu spoke.

"It's difficult."

Tamayo shook her head: "I can feel her hatred for me, her hatred for demons. It's almost impossible for her to cooperate with a demon."

“Ghosts are always different. Once Shinobu realizes that you are different from other ghosts, he will naturally understand you.”

Su Mu spoke.

Tamayo didn't quite believe it. She had met Shinobu Kocho and knew about her hatred for demons. If her sister hadn't stopped her, even Shinobu, on her sickbed, would have wanted to cut off her head with a knife. That hatred, as sharp as a knife, could still be felt now.

Chapter 235 Shinobu's True Smile (Part 2)

The conversation with Tamayo gave Su Mu a deeper understanding of Muzan Kibutsuji, and he was also glad about his previous choice. If he had recklessly hunted demons and relied on the power of devouring to improve himself as soon as he overcame sunlight, he probably would have been noticed by Muzan Kibutsuji much earlier.

Muzan Kibutsuji is known as the absolute ruler of demons because he has a certain ability to perceive each demon. This perception is related to the amount of blood he obtains from them; the more blood he obtains, the stronger his perception becomes, and he can even share real-time images with each demon.

If you attack a demon, the chances of being noticed by Muzan Kibutsuji are very high.

…………

When Shinobu Kocho woke up again, it was the next morning. Gentle sunlight streamed through the window, falling on the girl's disheveled face. Occasionally, a breeze would blow in through the window, and the girl's hair would sway gently in the wind.

The pain from my injuries is still there, but it feels much better than before. I think it's because I drank a lot of the herbal medicine prepared by Zhushi yesterday, and it worked very well.

She was reluctant to drink it before, even though the herbal soup was very effective, she just didn't like it.

It wasn't the bitter taste of the medicine that bothered her, but rather that it came from a ghost. Her hatred and aversion to ghosts made her instinctively dislike anything that came from them.

"Squeak..."

The door opened and Kanzaki Aoi walked in carrying a medical kit. Seeing Shinobu Kocho awake, she looked happy and said, "Shinobu-neechan is awake. You look great today."

Shinobu Kocho was an exceptionally skilled physician. She closed her eyes slightly, sensed her body's condition, and knew that her recovery was indeed progressing quite well.

However, she was so badly injured that she can only lie in bed now and can't even stand up.

Kanzaki Aoi came over with a medicine box and began to help Shinobu Kocho remove her bandages, prepare to change to new ones, and disinfect the wound.

The clothes were unbuttoned, the bandages were removed, revealing the numerous wounds underneath.

Several deep wounds were even near the heart, so deep that they were almost touching the heart.

Although they had met several times, each time Kanzaki Aoi felt a tightness in her chest. She would take a deep breath, suppress her emotions, and begin to help Kocho Shinobu clean and disinfect her wounds.

As the alcohol dripped onto the wound, the girl's brows furrowed slightly, yet she couldn't help glancing at the wound.

Kanzaki Aoi was carefully cleaning her wound, which had originally been very deep, but was now beginning to heal.

At this moment, Shinobu Kocho wasn't too concerned about the speed of the wounds' healing; rather, she was more concerned about whether these wounds would leave scars.

In the past, Shinobu Kocho probably wouldn't have cared much and would have thought it was normal for a swordsman to get injured and have scars, but now she's less willing to.

Upon seeing the condition of the wound, Shinobu Kocho, as a physician, only needed a glance to get a general idea of ​​what was going on. She knew that if she took good care of herself afterward, there would probably be no trace of it.

Having figured things out, Shinobu's tightly furrowed brows relaxed, and she rested her head on the pillow again, her long eyelashes trembling slightly.

In the past, she was the one treating others; now, she is the one being treated, which feels quite different.

"Sister Ren, the medicine you're preparing today is brewing, it'll be ready in a bit..."

While bandaging her wound, Kanzaki Aoi spoke in a low voice.

"I don't really want to drink it."

Shinobu Kocho closed her eyes slightly.

"Well, Mr. Su Mu has been working on this for a long time."

As Kanzaki Aoi bandaged the wound, she joked.

Shinobu's face flushed slightly, and she unconsciously turned her head away, somewhat unable to look Kanzaki Aoi in the eye.

After a long while, Shinobu Kocho turned around, her voice muffled: "He... he hasn't left yet?"

"No."

Kanzaki Aoi bandaged the last wound and then dressed Kocho Shinobu, covering her fair skin underneath.

In fact, apart from being a little short, Shinobu Kocho has almost no weaknesses.

In fact, compared to the height of most people here, Shinobu Kocho is not short; she is only shorter than Su Mu.
