Control the Butterfly Effect from Demon Slayer: Blade

After many days of multiple experiments, it can finally be confirmed that the drug that turns ghosts back into humans has been successfully developed!No errors and side effects!

Once the experiment was confirmed, everyone was very excited!
The most excited and impatient is Tanjiro.

On this day, after all the experiments were over, everyone gathered in the laboratory, preparing to witness this historic moment.

What is a historic moment?

Of course it was Nezuko who took the medicine and transformed from a ghost back into a human!

Tanjiro stood among the crowd with Nezuko, watched by everyone's worried and expectant eyes.

I don't know why, but at this time, Tanjirou, the person involved, is not so worried.

Seeing that everyone was restless, he smiled and comforted his companions instead:
"Don't worry, everyone. Haven't all the experiments been confirmed? There is absolutely nothing wrong with the medicine that turns ghosts back into humans! Don't worry, everyone!"

Seeing Tanjiro so free and easy, everyone was somewhat relieved.

While everyone was waiting, Zhu Shi walked over with a dose of pink potion.

Looking at the pink potion, everyone became serious.

Butterfly Shinobu took the potion, used a brand new syringe to draw a sufficient amount of potion, and handed the syringe to Tanjiro without hesitation.

Tanjiro had black lines all over his head.

Of course he knew what was going on.

The first few times that Nezuko's blood was drawn, it was his elder brother who did it himself, so Nezuko would not resist.

This time injecting medicine, of course, I have to let myself do it myself.

Holding the syringe in his hand, Tanjiro looked at the aggrieved Nezuko next to him, somewhat ruthless:

"Nezuko, hold on, this is the last time!"

After finishing speaking, he rolled up Nezuko's sleeve, exposing Nezuko's arm, and with Nezuko's aggrieved expression, he injected the medicine intramuscularly.

After the needle was pulled out for disinfection, everyone around looked at Mi Douzi, expecting her reaction.

Under the gaze of everyone, Nezuko really reacted quickly.

I saw Nezuko standing there, rubbing her eyes and starting to feel sleepy.

Seeing this, Zhu Shi and Die Die were overjoyed.

It's right to be sleepy. The process of transforming from a ghost back into a human cannot be carried out in a waking state, and can only be carried out in sleep first.

Nezuko became more and more sleepy, her eyes began to blur, she just leaned against Tanjiro and began to doze off.

Tanjiro supported his sister and looked at Horigake.

Fortunately, everyone was prepared, Zhu Shi instructed Tanjiro:

"Help Nezuko to my room, let Nezuko sleep well, my room is very close to here, and I can respond immediately if something happens."

Tanjiro nodded, picked up Nezuko who was already asleep, and walked out of the laboratory.

The next time is waiting, at least waiting for Nezuko to sleep for six or seven hours.

Horiyake looked at everyone who was still waiting in the research room, clapped his hands and signaled everyone:

"Everyone, the lab is so crowded. It's not a place for everyone to wait. Let's all go home first. If Nezuko wakes up, I will let everyone know as soon as possible."

The children nodded one after another, all obedient, and left the research room one by one.

Soon, there were only five people left in the laboratory.

The five people are: Horigaku, Butterfly Shinobu, Tsushima, Yushiro, and Yoya.

In fact, there is no point in waiting for the five of them to continue here.

But there are still some things that Horigake is more concerned about.

Horie looked at Tsuna beside him, and asked:

"Miss Zhushi, don't you plan to try this drug? If I'm not wrong, you want to change back to human, right?"

When Horie Koshi said that, everyone turned to Tsushima.

Zhu Shi was taken aback for a moment, and then seemed to be covering up a bit:

"Oh, I do have this idea, but it's not the time when Yushiro and I have turned back into humans."

"Oh? How do you say this?"

"If Yushiro and I are still ghosts, we don't need too much rest time, which can make our research more efficient and develop the other four drugs faster.

My idea is, after the research is over, after everything is over, I will consider whether to become human again. "

Everyone understands.

This is indeed the case. Ghosts usually don't need to sleep too much, and can spend most of their time on research and work.

This reason is indeed sufficient, and it is indeed the truth.

But this reason obviously failed to completely hide it from Horigake.

He looked at Zhu Shi's expression calmly, and clearly felt that Zhu Shi had other plans.

So Horigake took advantage of the situation and said:
"After the research is over, Ms. Zhushi will turn back into a human, and don't wait until everything is over.

After everything is over, after the final decisive battle, Wu Mi will definitely be killed by me.

And when Wu Mi died, all other ghosts in the world would die together with Wu Mi as if they were buried.

Although Miss Zhushi and Yushiro are not under Wu Mi's control, there are Wu Mi's cells in his body. If Wu Mi dies, whether his cells will riot or collapse... No one can say for sure.

In case your two lives are in danger at that time, it is better to use this drug to turn back into a human before the final battle and after the research work is over. "

The reasons given by Horigake are more sufficient and more thoughtful.

Juse seemed completely unaware that Horigaku would say these words, and his expression froze for a moment.

"Hmm... what Horigake said makes a lot of sense, let's talk about it when the time comes."

Now, not only Horigake noticed the abnormality, but also Butterfly Shinobu and Yoya beside him noticed the abnormality.

Yaozai is okay, he has insight into people's hearts, and has some guesses about it, but he doesn't think much about it.

Butterfly frowned, obviously starting to think:
Judging by Miss Zhu Shi's expression, it seems that she doesn't particularly want to turn back into a human.

why is that?After hundreds of years of suffering, it stands to reason that Miss Zhu Shi should be eager to change back to a human being. Why did she change her mind at this time?
Could it be... Could it be that Miss Zhu Shi wanted to maintain her identity as a ghost after Wu's tragic death! ?Are you still a ghost?
Even... become the new generation of ghost king after Wu Mi! ?
Butterfly endured the more she thought about it, the more outrageous it was!

After thinking about it, she herself felt that she had made up her mind, so she shook her head quickly.

No, no, Miss Zhu Shi is definitely not such a person, she thinks too much.

Why is Miss Zhu Shi doing this?
Butterfly couldn't understand it for a while.

Hori Yue understood Zhu Shi's thoughts, and had some guesses about Zhu Shi's plan.

He sighed inwardly, and decided to intervene.

It's impossible not to interfere, he couldn't bear to watch such a great beauty disappear.

However, whether it is interference or persuasion, this occasion is not suitable.

So Horigake said to Butterfly Shinobu and Yoya:

"My lord, Sister Shinobi, let's go back first, Nezuko will sleep for a long time now."
