Control the Butterfly Effect from Demon Slayer: Blade

Horiyake came to the laboratory for the first time, and even rushed in very excitedly!

"Drug research succeeded!? A drug that turns ghosts back into humans!?"

As soon as he broke into the research room, he saw Butterfly Ninja, Zhu Shi, and Yushiro, three people in white coats, silently surrounding the research table, observing something.

Ignoring the need to change into a white coat, Horie walked over directly.

At this moment, Zhu Shi raised his head and smiled at Horigaku:

"Yeah, thanks to Nezuko overcoming the sun, after Nezuko overcame the sun, we took a part of Nezuko's blood for research, and then broke through the research barrier in one fell swoop, and the research was successful."

"Well, let me see."

Horiyake walked over impatiently.

Walking over to take a look, there are several research test tubes on the research table in front of them. Inside the sealed research test tube is a strange potion.

Why do you say strange?
Because the color of this potion is pink!
It's not the kind of light and immature girly pink, but a kind of deep pink that tends to be red.

oh!correct!It is basically the same color as Nezuko's blood flame!
Seeing that the medicine in the test tube turned out to be of this color, Hori Yue couldn't help hesitating:
"This... This is the medicine that turns ghosts back into humans? Why does the color look a little strange?"

When it comes to this question, Butterfly Shinobu is also a little embarrassed:
"We don't know what's going on. According to the theory, it is indeed a drug that turns ghosts back into people. We have indeed succeeded in research."

"According to theory?" Hori Yue looked at Butterfly helplessly: "In other words, the drug that turns ghosts back into humans is only theoretically successful, and has not been tested yet, has it?"

Butterfly nodded helplessly:
"We can be sure that the theory is [-]% correct, but it has not been tested yet."

"This... has never been tested..."

While Horigake was hesitating, Tanjiro, who got the news, rushed into the research room with his younger sister Nezuko in a hurry.

"I heard that the research was successful!? Is that so!? Is it true!?"

The four turned their heads to look.

Tanjiro was sweating all over his head in a hurry, he led Nezuko who didn't know why, and just rushed in like that.

Horie took a step back and moved out of the way, allowing Tanjiro and Nezuko to see the pink potion in the test tube, and then introduced to them:

"The drug that turns ghosts back into people has indeed been successfully researched, that's it."

Tanjiro was still very excited, very excited.

But after seeing the color of this potion, the complicated mood just now stopped immediately.

"This... This is the medicine that turns ghosts back into people? Why is it such a strange color?"

Horigake spread his hands there:

"You ask me who I ask? This is not what I researched."

Tanjiro turned his suspicious gaze to the research trio again.

The trio was also a little embarrassed.

It was Zhu Shi who stood up and explained helplessly:

"We don't know why it is this color, but there is absolutely nothing wrong in the theory, but it has not been tested exactly, so we don't know how effective it is."

Hearing this explanation, Tanjiro inevitably hesitated.

He didn't dare to use it for his sister without experimenting.

At this moment, two more people pushed open the door of the research room and walked in. When they came in, their tone was still excited:
"I heard that the drug research that turns ghosts back has been successful? Is it true?"

Everyone looked.

It turned out that it was Yaozai and Tianyin who rushed over as soon as they got the news.

The couple stood at the door of the research room, looking at the people in the research room, everyone looked at each other in blank dismay.

Yaozai's sharp eyes saw the pink potion on the research table immediately.

"Could it be... this is the drug that has been researched to turn ghosts back into humans? But why is it this color? This color... what a girl."

Everyone was embarrassed and fell silent.

Immediately afterwards, the children also knew that the news rushed in, and their reactions were exactly the same as everyone else's.

In this way, everyone who should get the news got the news, and everyone who was supposed to come also came. For a while, there were a lot of people in this research room, which seemed a bit crowded.

Although there are many people, but in the end, there are only five people in charge.

First of all, Tanjiro, he is the only family member of the patient, and it is appropriate to stand beside the medicine.

Then there is Yaozai, how can he say that he is also the leader of the Ghost Killing Squad, and his status is here.

There is Hori Yue, also because of identity and status issues.

The other two are Zhu Shi and Butterfly Shino who developed this drug.

The five people formed a group, and everyone stared at the pink medicine on the research table, without saying a word for a long time.

Staring and staring, the eyes of the other three people involuntarily turned to Zhu Shi and Butterfly Shinobi.

Zhu Shi was fine, just smiled.

Butterfly couldn't bear it anymore, and said directly angrily:
"How many times have we said that there is absolutely no problem with the theory, this is indeed the drug we have researched to turn ghosts back into humans!
As for why it is this color, we don't know! "

Yaozai withdrew his impolite gaze and made a suggestion:
"In any case, you can't let Nezuko use this drug without authorization. It's better to experiment before using it, and let Nezuko use it after confirming that there is no problem."

Hearing this, Tanjiro nodded vigorously.

He didn't want his sister to be an experimental product. Just looking at the color of the drug, he found it a bit strange, although Tanjiro was very kind to this color.

Speaking of conducting experiments, Zhu Shi frowned:

"So, who should experiment with this drug?

It stands to reason that, as a researcher of this drug, I should try it myself, but..."

Horigake followed up with Tsuse's words.

"But other medicines haven't been researched yet, Miss Zhu Shi can't risk her life."

Everyone nodded, expressing their approval of Horigake's worry.

The question comes back to the original question, who should try this drug?
Where can I find someone willing to cooperate?What about ghosts that take the initiative to transform back into humans?

Suddenly, everyone had an idea at the same time, and the five of them looked at Yushiro over there!
Yushiro just wanted to run away, but he found that everyone's eyes were on him, and his face immediately became much darker.

Yushiro subconsciously felt that something was wrong when he said that the experiment was going to be carried out.

I didn't expect it, I didn't expect him to try to reduce his presence as much as possible and wanted to leave, but he was discovered in the end!
Facing the earnest gazes of the five bosses, Yushiro's scalp felt numb.

He couldn't help looking at the medicine on the research table again, especially seeing that color!
Obviously, the success of this drug research also has its own contribution.

But when I looked at the drug again at this time, why did I feel a chill on my back?
