In a basement room next to the Demon Slayer Corps Headquarters, Musashi pushed open the basement door, carrying a very rough wooden box on his back.
Yushiro was carrying several reagent bottles and heading into the inner room when he heard the noise, turned to see Musashi, and then showed a very displeased expression.
"Is Tamayo here now?" Musashi's excited mood still hadn't calmed down.
After encountering the demon that could track targets through blood, he immediately knocked it out and brought it to Tamayo.
However, the journey was too long, and he couldn't make it in one night. As dawn approached, he had no choice but to cut down two trees, piece together a very crude box, and then drag it with both hands, carrying it on his back all the way here.
The demon woke up several times along the way. Whenever Musashi noticed, he would immediately give it another heavy blow. So far, the demon's neck has broken and healed, broken and healed, about ten times.
Because the box was too crude, carrying this demon meant Musashi couldn't pay attention to his Kasugai Crow, which was tied to his waist, causing it to suffer greatly from the bumps on the road. Musashi could only silently apologize to his Crow in his heart.
Of course, he did this out of necessity and definitely not to get revenge on his Crow.
Yushiro looked at Musashi's strange appearance with some confusion, but he didn't want to bother with it and simply told Musashi, "No."
Hearing Yushiro say no, Musashi felt very confused, so he asked again, "It's daytime now, where would Tamayo be if she's not here?"
Yushiro heard him and said impatiently, "How would I know? Anyway, Lady Tamayo isn't here, so you should leave quickly."
With that, he was about to take the reagent bottles into the inner room.
Musashi didn't quite believe Yushiro's words. Just as he was about to ask again, a sound suddenly came from the box on his back.
Musashi noticed, put the box on the ground, and opened the heavy wooden lid. The demon stretched out its hand.
"Spare… spare…"
The White-Haired Demon mumbled weakly. Musashi pulled it out and then delivered a palm strike to its already protruding neck.
Thud!
"Ugh…"
A dull sound rang out, and the White-Haired Demon let out a muffled groan before falling unconscious again. Its already hunched back now made it look exactly like a turtle poking its head out when it stood up.
"What a hassle…"
Musashi sighed. He had repeated this action nearly ten times along the way.
"Yushiro, you can't lie to Mr. Musashi like that."
At this moment, Tamayo's voice came from the front. Immediately after, she pushed open the door of the room ahead and walked out, wearing a white outer garment, which seemed to be for protection.
"Yes, Lady Tamayo!"
As soon as Tamayo appeared, Yushiro immediately quieted down, standing at attention and answering Tamayo loudly.
Lady Tamayo, even after just finishing an experiment, is so beautiful!
Yushiro's cheeks flushed slightly as he shouted in his heart.
"I apologize, Musashi. May I ask what you need me for?"
Tamayo said to Musashi while taking off her outer protective suit.
"Lady Tamayo, I might have found a way to find Muzan!" Musashi said excitedly.
Tamayo paused after hearing Musashi's words, then asked Musashi, "What is it?"
Musashi heard her, lifted the demon out of the box. This demon had just been struck by Musashi and was still unconscious.
"It's him." Musashi pointed to the White-Haired Demon, then, without beating around the bush, explained directly to Tamayo, "This demon's Blood Demon Art can track targets through blood. If we let him use Muzan's blood to activate his Blood Demon Art, then we might be able to find Muzan's whereabouts."
Musashi was extremely excited as he explained, but Tamayo's next sentence immediately brought his soaring hopes crashing down.
"From what I know of Muzan, if this demon uses its Blood Demon Art with Muzan's blood, it will trigger the Demon and die immediately, and its Blood Demon Art will then become useless." Tamayo said, looking at the unconscious White-Haired Demon.
Musashi's excited mood immediately vanished upon hearing this, replaced by deep regret.
"Ah, then we can only…"
Just as the disappointed Musashi was about to kill the White-Haired Demon directly, Tamayo spoke again.
"However, I can try to see if I can extract its Blood Demon Art. This way, when using this Blood Demon Art, we won't be limited by the demon itself."
Tamayo was also somewhat excited; the ability of this Blood Demon Art was truly too important for finding Muzan.
"Can something like that be done?"
Tamayo's words deeply shocked Musashi. He had never imagined that such a thing could be done.
"If Lady Tamayo says it can be done, then it definitely can be done. How dare you question…"
"Yushiro!"
Yushiro immediately glared and was about to scold Musashi after hearing his questioning, but Tamayo interrupted him before he could finish his sentence.
"Yes, Lady Tamayo!"
Yushiro understood Tamayo's meaning and quickly shut his mouth, no longer speaking.
Lady Tamayo called my name again! This is amazing!
After disciplining Yushiro, Tamayo turned back to Musashi and replied, "I can't guarantee it, but there's definitely a possibility, and it's not small.
I once treated a patient in Asakusa who had just been turned into a demon by Kibutsuji Muzan. Not long ago, after studying the blood of the Upper Moon and Nezuko, I successfully helped this patient regain his humanity, and during this time, I extracted his Blood Demon Art.
However, this patient hadn't been a demon for long, and I had been continuously using medication to suppress him during that period.
Therefore, I'm not sure if this can be done for other demons."
Tamayo's words made Musashi see hope again. He handed the White-Haired Demon to Tamayo and then bowed deeply to her.
"I beg you, Lady Tamayo…"
"I will do my utmost to do this." Tamayo smiled upon seeing this and assured Musashi.
Then she continued, "Additionally, if you encounter any demons later who possess a Blood Demon Art related to spatial abilities, I hope you can also capture them and bring them here.
After our first encounter, I searched for Muzan for a while. Although I couldn't find his whereabouts, I discovered that Muzan likely has subordinates with spatial ability Blood Demon Arts.
Although this is just a guess, I think it's better to be safe than sorry. We must make the most thorough preparations possible, otherwise, once we fail, it will be very difficult to get another chance."
"Spatial ability, huh… I've noted it. If I can find one, I'll capture him and bring him to you."
Musashi nodded and said.
