Control the Butterfly Effect from Demon Slayer: Blade

Seeing that Horitake recognized the softness, Butterfly Shinobu let him go, and he had the tendency to rise high and fall gently.

Shaking his head, Butterfly Shinobu turned around, intending to continue his daily work:

"Okay, no nonsense, it's time to get back to work."

Speaking of business, Horigaku's spirit immediately shook, standing next to the butterfly ninja's research table, watching the butterfly ninja fiddling with those bottles and jars, and couldn't help but ask:

"Sister ninja, why is there no potion?"

The potion mentioned here is, of course, the life supplement potion.

For more than a year, the main work of the two of them has been to prepare for the life replenishment potion in the future.

While carrying out his work, Butterfly Shinobu replied

, "The potion quota for these two months has been prepared, and the rest of the time, I am busy with my own personal work."

Pointing to the butterfly ninja's research table, Horitake stopped talking:

"Sister Shinobi, this private job of yours is... Development of poisons?

"Yes, you also know that although I am a pillar, my strength is not so strong, and I don't have the wrist strength to cut off the neck of the ghost, so I can only kill the ghost through poison."

Although the wisteria flower poison I have been using is also very powerful, I don't think it is poisonous enough, so I wanted to develop a new type of poison to increase my lethality.

"So it is."

Horitake nodded in understanding.

In the original work, Sister Shinobi studied more than just poison.

In the original work, Sister Shinobu has made up her mind at this time and has decided to feed Tong Mo, so this time period has begun to dispense poison in her body and gradually turn herself into a poisonous person.

Of course, that was the situation in the original work, and now the situation has completely changed, and after untying the heart knot of Sister Ninja, Sister Ninja no longer plans to die.

But people have pursuits.

Don't turn yourself into a poisonous person, don't choose such an aggressive way, butterflies can't help but choose another way, to increase their strength, increase their lethality.

There is no doubt that enhancing the toxicity of the poison is her preferred goal.

This is why Butterfly Shinobu is now turning to continue studying poison.

Horitake walked to the next room, changed into a white coat and returned, also sitting in front of the research table, sitting side by side with Butterfly

Shinobu: "Sister Shinobu, I'll help you."

Glancing at Horitake beside him, Butterfly Shinobu doubted

Horigaku's professionalism: "Horigaku, if it is a life supplement potion, I still have some confidence in you, after all, the prescription of the potion came from you.

But you're not good at configuring poison, this is my area of expertise, can you really help?

"Don't underestimate me, sister Shinobi, maybe after I help you, you will have a miraculous effect, and you can quickly develop a new and more poisonous poison."

Even if I can't help you, at least it should be fine to help you fight, right? "

Hit the hand? Aoi can do this too.

"Please, Xiao Aoi's family has enough housework every day, and you also want someone to help you be an assistant, she is your sister, not your squeezed employee!"

Don't squeeze Aoi, come on, squeeze me! It's okay to squeeze me dry! Use me as much as you can! This

is so strange and too easy to think crookedly.

Butterfly Shinobu glared at Horitake with a slightly red face, and said coquettishly:

"Don't say such strange things! If you want to help, just help, don't add to the mess!

After that, the butterfly dispelled the anachronistic thoughts and pictures in his mind, concentrated on it, and continued to devote himself to developing new poisons.

Of course, Horitake didn't mess around, and he was also dedicated to helping Butterfly Shinobu develop new poisons.

How to say, developing a new poison is really not a simple matter.

If you really develop it from scratch, it will undoubtedly be extremely difficult.

Fortunately, their research and development of new poisons is not without foundation, and the old poison currently used by Butterfly Shinobu, that is, the wisteria flower poison she now uses to kill ghosts, is the basis of the current research.

As long as on the basis of this wisteria flower poison, further increase its toxicity, make the lethality of this poison more great, make this poison more toxic, then the new poison is successfully developed.

But this kind of thing is not simple.

With the research, Horitake found that the wisteria flower poison that Shinobi sister has used for many years is already a very mature and effective toxin, and it is difficult to further strengthen on the basis of this toxin.

The two of them studied for several days.

With further research, the mood of the two people became more and more bad.

Because through their research, they found that the wisteria flower poison currently used by butterfly ninja has almost reached its peak.

Reaching the apex means that it cannot be broken through and cannot be further strengthened.

The potential of wisteria flower poison is like this, no matter how it is developed, it is also to this extent.

It's not that the two of them haven't looked for alternatives to other poisons.

However, the only plant that can kill ghosts is wisteria flowers, and the other plants have little effect on ghosts.

In this way, the research and development of Horitake and Butterfly Shinobu fell into a bottleneck and seemed to have reached a dead end.

The research was greatly hindered, and the two people were not in a good mood.

Horitake and Shinobu Butterfly are two people at the top of the food chain in the butterfly house, and these two are not in a good mood, which causes the atmosphere in the entire butterfly house to be trembling.

As the bottom of the food chain, the five younger sisters of the butterfly house are simply shivering during this time.

Usually, Horitake and Butterfly Shinobu are fine in the research room, and they don't go out of the research room as they please.

But once they left the research room and brought this bad mood out of the research room, the five younger sisters of the butterfly house were inevitably a little scared.

No way, these two big guys have a face at the same time, and at the same time they look distressed and angry, how do you let their five sisters deal with themselves?

If you make the two of them angry because of some little thing, it must end badly!

So during this time, when Butterfly House was usual, the five younger sisters acted quite cautiously, not daring to be naughty at all, not daring to be naughty at all, especially for fear of angering Horitake and Butterfly Shinobu.

Fortunately, Horitake and Butterfly Shinobu are not unreasonable people.

They are not the kind of bastard parents who beat their children out of anger when they have nothing to do, although they are in a bad mood and have a bad job, they will definitely not be angry with their children.

In this way, although the atmosphere of the butterfly house was a little dignified, nothing bad happened.

In this way, several days passed, and the research of Horitake and Butterfly Shinobu continued in the bottleneck without any breakthrough.

Not only Butterfly Shinobu is distressed, but Horitake is also distressed.

He often wondered:

Could it really be that he had reached a dead end? A road to the dark?

It's not that they haven't changed directions.

But the other directions are also dead ends, and have no effect.
