Control the Butterfly Effect from Demon Slayer: Blade

It was Horigake's turn to introduce his children to Tsuyoshi and Yushiro.

From left to right, Horigake introduced in turn:
"This younger sister is Kanao, sister of Shinobi, and her stepson.

This is Xiaokui, the big housekeeper of our Butterfly House. If Miss Zhushi has any troubles in life in the future, just ask Xiaokui to solve them.

This is Xiaoqing, Xiaocheng, and Xiaonasui. These three younger sisters are also in charge of logistics in the butterfly house.

This is Yae, my junior sister and my stepson.

Tanjirou doesn't need an introduction, you also know Ms. Zhushi.

This is Shanyi, my younger brother and step-son.

This is Inosuke, who is sometimes rude, but also my stepson.

The number of people is a bit large, I don't know if it will cause trouble to Miss Zhu Shi. "

After hearing this, Miss Zhu Shi smiled and shook her head:

"Where? I can see that everyone is a very good person. Please give me your advice in the future."

Saying so, Zhu Shi bowed again.

Seeing this, the nine children hurriedly bowed in return.

Everyone knew each other. At this time, Butterfly came over with a smile and said to Zhushi and Yushiro:
"Then, let me take the two of you to work and live?"

"Okay, excuse me, Miss Shinobi."

"Wherever it is, don't bother."

Just like that, the smiling Butterfly Shinobu, with the gentle Miss Zhushi, and the stinky Yushiro, walked towards the research room on the other side of the Butterfly House.

While walking on the road, Zhu Shi also discovered something else.

When she walked to the butterfly house, Miss Zhushi found that the windows here seemed to have been sealed with thick wooden boards from the outside.

Why seal it?
The reason is simple, to block the sun.

This must be the preparation made in advance in the Butterfly House for their convenience.

Thinking about this, Miss Zhu Shi felt apologetic.

Soon, through the corridor, Butterfly Ninja brought the two of them to their daily research room.

Pushing open the door of the laboratory, three people entered. Butterfly Shinobi introduced the two of them to visit their laboratory. Ms. Zhushi and Yushiro also carefully observed the place where they would work in the future.

After observing for a while, both of them were very satisfied.

Materials and utensils are very complete.

Basically, as long as you come, you can work immediately.

Butterfly Ren also asked very intimately:
"Is there anything else missing? I can get ready right away."

Miss Zhu Shi hurriedly said politely:
"It's already very complete. As expected of Ms. Shinobi's laboratory, it is as thoughtful and complete as the laboratory at my house. If there is anything needed, I will just tell Sister Shinobi."

"That's good. For our future work, Miss Zhu Shi must not be polite."

"I will, thank you Miss Shinobu..."

The two women became very polite just like that, smiling at each other, and seemed to be having a good time talking.

Yushiro was attracted by other things in the laboratory.

He pointed to the big safe in the research room, and couldn't help asking:
"Excuse me... what is that thing? Is it a safe? Why is there a safe in the research room? Are there important materials stored in it?"

Butterfly endured a look and immediately hesitated.

This safe is full of syrup.

There is no doubt that this is the most important secret of the Ghost Killing Squad, can she say it?

Miss Zhushi immediately sensed Butterfly's embarrassment and hesitation, stepped forward to stop Yushiro, and softly reprimanded Yushiro:
"Yushiro, that's too rude."

"Uh...sorry, Lord Zhu Shi."

"Actually, there is nothing bad to say, but it is indeed the most important secret of our ghost killing team."

After saying this, Horigake walked in from outside the laboratory, and explained casually as he entered:

"If it was someone else, I really wouldn't believe it.

But since we have brought Miss Zhu Shi into our research room, it means that both me and the master trust Miss Zhu Shi very much.

If Ms. Zhu Shi is interested in this matter, I can also tell you.

It is indeed a safe. In the safe, sister Shinobu and I have prepared for a long time, a potion code-named syrup.

This potion has no other effect, only a heaven-defying effect, which is to replenish the life force lost by people, and at the same time replenish the life span lost by people! "

"What!?" ×2
Hearing what Horigake said, neither Tsuyoshi nor Yushiro could remain calm, and the two of them were dumbfounded, almost pale with shock.

Out of subconscious opposition to Horigake, Yushiro was the first to not believe it:
"Impossible! A potion that replenishes life and vitality... I've never heard of it."

Horigake wasn't used to Yushiro either, so he replied coldly:
"Just because you haven't heard of it doesn't mean you haven't!
I obtained the prescription of this potion unintentionally, in order to replenish the lost vitality of us Ghost Killing Team Pillars. "

"The vitality lost by the pillars?"

Zhu Shi frowned, puzzled.

Horigake smiled and explained:

"Miss Zhushi is well-informed, have you heard of Zebra?"

"Brindle? Hiss..."

Being reminded by Horigake, Zhu Shi immediately gasped and recalled certain memories.

Thinking back then, the reason why he betrayed Wuyan and left Wuyan's side was because of the help of Jiguo Yuanyi, that is to say, Zhu Shi knew Jiguo Yuanyi and knew him a little bit.

Miss Zhu Shi immediately thought of the sun-like lines on Ji Guoyuan's forehead.

Yes, that's tabby.

Zhu Shi also knew that although Ji Guoyuan lived to be more than 80 years old, it was all because he was a special pervert, and his life span was not lost when he turned on the markings.

As far as Zhu Shi knew, none of the other swordsmen who started markings lived to the age of 25.

Then the younger brother of Ji Guoyuanyi, didn't he become a ghost because he pursued strength too much. After turning on the markings, he didn't want to die at the age of 25 and wanted to pursue strength for a longer time?
In an instant, Zhu Shi thought a lot and wanted to understand a lot.

She looked at Hori Yue excitedly, and walked up to Hori Yue:
"So that's how it is! This potion is to supplement the vitality of those pillars who have turned on the stripes! In this way, they can live past 25 years old and have the original life span!"

Speaking of this, Miss Tsuyoshi became more and more excited, she took a step forward, and got closer to Horigaku under the ugly eyes of Butterfly Shinobu and Yushirou.

Zhu Shi couldn't wait to ask:

"Mr. Horigake, may I ask, how many pillars of the Demon Slayer Squad have their stripes turned on?"

"Counting me, six out of ten have stripes on."

"Six out of ten? So it's more than half!"

Hearing this answer, Miss Zhushi couldn't hold back her excitement any longer, she even grabbed Horigaku's hand directly:
"Great! God bless!"
