The next day, in the morning.

Shiho Miyano woke up comfortably from his sleep.

She felt as if she hadn't slept so relaxed, so steady, and so freely for many years.

I opened my sleepy eyes dimly, and subconsciously touched the still warm quilt beside me:

The man next to the pillow was gone.

Of course, this pillow man refers to her sister Akemi.

After a long heart-to-heart talk with Lin Xinyi last night, the atmosphere between the two was very good.

Miss Shiho wants to get tired of her boyfriend while the iron is hot.

But Lin Xinyi felt that he was sticking together with a little girl in the middle of the night and talking about love, which felt a little weird.

Seeing that the time was in the early hours of the morning, Lin Xinyi asked Zhibao to go back to rest and deal with it on the sofa for a night.

Miss Shiho went back to the bedroom by herself and got into her sister's bed.

Just like when I was a child, I hugged my sister's arm and fell asleep beautifully.

"That's nice..."

Shrunk in the warm quilt, a touch of happiness appeared on Shiho's little face:

She couldn't have imagined that she could live so freely with her beloved sister and boyfriend like she is now.

With such happiness in mind, she sat up from her bed.

Because Lin Xinyi hadn't bought her childhood clothes yet, she simply put on the shirt that her sister changed out of as a dress just like yesterday.

Tying up her somewhat loose neckline and rolling up her overly long sleeves, Miss Shiho rolled out of bed, rubbed her sleepy eyes, and pushed open the bedroom door with her little feet and big slippers.

There was a faint aroma of food in front of him.

It seems to be cooking porridge.

Because of the aroma of the food, this long-idle villa suddenly has a warm atmosphere of life.

Shiho Miyano took a deep breath, looked at the morning light spilling in from the window, and felt that the whole person was refreshed:

Speaking of which, this is the first time in her life...

For the first time, I have someone I like. I had the opportunity to live with my sister.

Two happy things coincided, and she got a happy time like a dream.

Miss Shiho walked down the stairs and came to the living room in this happy mood.

And then she saw...

Her Akemi sister was sitting with her back to her, sitting in front of Lin Xinyi.

And Lin Xinyi didn't seem to notice her arrival.

He was engrossed in reaching out his hand and gently "caressing" her sister's face.

Shiho Miyano: "......"

"What are you doing?"

Her childish voice sounded mournfully in the empty villa.

Like a ghostly ghost, Miss Shiho floated down the stairs with a cold and unwarm face.

"Huh? Shiho, are you awake? ”

Akemi Miyano turned her head and revealed a face covered in "mud":

"Mr. Lin is making a face model for me."

"Face mold?" Miss Shiho looked at Lin Xinyi suspiciously.

Lin Xinyi explained in a natural tone:

"The face mold is the substrate on which the disguise mask is made."

"To achieve perfect transfiguration, the base of the human skin mask must fit perfectly to the human face."

"After making the face mold, I will make the whole disguise mask for your sister on the basis of the face model, and she will be able to go out as 'Kana Asai'."

"Otherwise, it won't be convenient for her to go out to buy things."

"Especially..."

Saying that, Lin Xin took a look at Xiao Zhibao, who was still wearing his sister's shirt as a dress:

"It's not convenient for me and Asai to help buy your girls' clothes."

He came here this time, in addition to seeing Shiho, mainly to complete the work of giving Akemi a disguise.

First help Akemi Miyano make a few masks to deal with the backup, and then let her slowly learn the "Transfiguration Course" by herself.

After learning it, she can disguise herself and teach Shiho by the way.

"Well..."

After listening to these explanations, Shiho Miyano's cold little face finally became a little gentler.

Then, I saw Lin Xinyi carefully help to coat Akemi's face with a layer of "mud mask" made of unknown Kexue materials.

In the same way that the shooting residue on the surface of the object is extracted with AC paper, the details are modified with fingers, and they are pressed and compacted inch by inch.

Wait until it dries, and then gently remove the "mask", and the backing of a human skin mask is made.

The whole process is like baking flatbread... It's just that the operation is more detailed.

In this way, Lin Xinyi used a technique that gradually became proficient, and burned several cakes on Akemi's face back and forth.

And throughout the whole process, Miss Shiho sat next to her, with a cold little face, quietly observing.

She didn't speak, but it was as if an invisible cold cyclone had accumulated around her, causing the temperature to drop.

The sluggish Lin Xinyi didn't notice it.

It was Akemi Miyano, who felt the meaningful gaze of her sister in time.

Since letting Zhibao know how she was rescued yesterday, this kind of little eyes that forget her sister when she has a boyfriend, and even beware of her sister, she can see it from time to time:

"Ahem..."

"The face mold is almost done, and the porridge should be cooked."

"Shiho, Lin, let's go have breakfast first!"

Akemi Miyano wiped her face with some embarrassment, then stood up and hurried to the kitchen.

Miss Zhibao didn't say much, just followed Lin Xinyi and sat down at the table.

"Let's eat."

Akemi Miyano carefully helped her sister and brother-in-law set the tableware, and carefully served them porridge and poured milk.

Seeing his sister's careful and busy appearance, Shiho's expression quietly became soothing:

When they were children, when the two sisters depended on each other, the elder sister always played a role similar to that of a mother, taking care of her like this.

And now, as if in a dream, she experienced this warm feeling again.

Sitting at this dining table, eating breakfast comfortably with my sister and boyfriend...

It's as if they are no longer members of a criminal organization wandering in the dark, but an ordinary, happy family of three.

"Hmm... Wait..."

Miss Zhibao's face darkened:

Now this picture does look like a family of three.

But no matter how you look at it... She was like a little daughter, not a hostess.

It's her mature and beautiful sister, who looks more like Lin Xinyi's lover at this time.

"No..."

That lingering sense of insecurity has returned.

She thought about it for a while, but she didn't have the heart to eat, so she put down her chopsticks and said to Lin Xinyi with a solemn face:

"Lin, I've thought about it too..."

"We can't do nothing but wait for me to grow up."

"So, I want to try to develop an antidote."

"Antidote?!" Lin Xinyi was slightly stunned: "There is an antidote to this thing?" ”

"There should be."

A look of remembrance appeared on Shiho's little face:

"APTX4869 wasn't a poison developed simply to kill people, but a drug I recreated from the mutilated materials left behind by my parents."

"Hmm... You're that woman's student, you should know. ”

As she spoke, her expression became slightly strange.

"Anyway... APTX4869 can induce programmed cell death, but at the same time enhance the activity of telomerase, thereby increasing the proliferative capacity of cells. ”

"Under normal circumstances, it will cause the death of the user, but due to the accidental action of the cell self-destruction program, all the cells of bones, muscles, internal organs, and hair except the nervous system will degenerate to early childhood."

Lin Xinyi: "......"

Here it is, it's like this again...

You'd better just tell me it's a magic potion...

Don't just talk about a few technical terms, just tell me it's a scientific product! ‵′︵┻━┻

When I heard Conan introduce the scientific principles of his pair of "foot strength" before, Lin Xinyi wanted to complain.

Now it just so happens that the scientist himself who developed the APTX4869 is in front of him ...

Lin Xinyi pondered for a moment, and finally asked uncontrollably:

"What about the conservation of mass and energy?"

"From an adult to a child, where did the mass that disappeared out of thin air go?"

"It's turned into energy."

Miss Shiho replied with a professional and serious look.

Lin Xinyi: "......"

If these dozens of catties of meat are converted into energy, they will be released in this Tokyo city.

That lethality... Mr. Li Mei is expected to be willing to bow down.

"In short, this involves the theory of quantum science, and you don't understand it." Shiho Miyano added.

"Oh... Quantum science, I see. ”

Lin Xinyi finally got a satisfactory answer:

Quantum science, like internal forces and magic, can reasonably explain all kinds of unscientific settings.

And now that you have this reasonable setting...

"Is it possible to develop an antidote?" Lin Xinyi asked again.

"Hmm." Xiao Zhibao nodded: "So, I need two things now." ”

"One, the APTX4869 you took from the lab last time."

"Having enough drug samples in place can greatly improve the speed of doing reverse studies."

"Oh, that's easy to say."

Hearing this, Lin Xinyi immediately put his hand into his pocket and fumbled and took out a few APTX4869 capsules.

Miss Shiho's expression suddenly became a little subtle:

"You... What are you doing with all these pills? ”

"Self-defense." Lin Xinyi replied unabashedly: "If you encounter an enemy who can't be dealt with, you can use this medicine to poison him." ”

Shiho Miyano: "......"

What she resents and loaths the most is that someone uses the medicine she developed to kill people.

And now, hearing that her boyfriend actually used her own medicine as a murder weapon, Xiao Zhibao felt in his heart...

Still a little happy?

"This medicine can help him and keep him safe..."

"That's a good thing, isn't it?"

Miyano Shiho thought so in his heart, but he didn't think there was anything wrong with his boyfriend using the drugs he developed to defend himself.

"You take it, I still have a few at home."

"If it's not enough, I'll ask for gin."

Lin Xin handed the medicine to Zhibao, and then asked:

"And what about the second thing?"

"I need a lab, at least, with all the basic equipment for the experiments."

“.......”

Hearing this, Lin Xin fell silent for a moment.

A biological laboratory, where a random piece of equipment comes out, can bankrupt him.

"Don't think about the lab..."

"With my current money, I don't think I can even afford a pipette gun."

"Huh?" Xiao Zhibao was slightly stunned when he heard this: "You... Why do you only have so much money? ”

"I still want to know..."

"Where is all this money spent?"

Lin Xinyi sighed with some resentment.

He really wanted to know that the original owner didn't have any luxury items in his house, how could he make the monthly salary of 890,000 so clean!

If it weren't for the recent money from Akemi Miyano's wallet, coupled with the support of Asai Narumi, he wouldn't even be able to afford to eat.

"Hmm..."

Miss Shiho lowered her head a little embarrassed.

I didn't feel it when I used to let men swipe their cards.

Now that she's really been chased, she finds out... What she used to squander turned out to be her family's money now.

"And, apart from the problem of lab equipment..."

"I'd like to add a third point."

Lin Xinyi added seriously:

"Is it really safe to develop an antidote?"

"There are too few samples that get smaller after taking the drug, and there is no way to do animal testing, right?"

That's what worries him the most.

When a new drug is launched, it stands to reason that it must first go through animal testing and clinical trials to determine that the drug is safe and effective.

But the problem is that now there are only two people who have become smaller after taking the medicine, Shiho and Conan.

If you can't test the drug with mice with the same symptoms of getting smaller, let people try it directly...

Not to mention whether it works or not, what should I do if I try to kill someone?

"I... I'm sure. ”

Miss Shiho thought for a moment, and finally said firmly:

"Lin, trust my abilities."

"Since I can develop a medicine that makes people smaller, there must be a way to develop an antidote."

Lin Xinyi: "......."

Indeed, it was he who fell in love.

Drugs that make people smaller are not scientific in the first place, and there is no need for him to worry about the safety of the antidote according to the scientific drug development process.

Anyway... Although his little girlfriend still claims to be a scientist, in his mind, she is actually like an alchemist.

"Well, the main problem now is the lack of money."

"And, if you can..."

"When the antidote is developed, I still don't want Zhibao to try the drug yourself."

"Find a 'guinea pig' with the same symptoms to try, at least, it's safer for you."

Not only is there money, but also willing to pay for the research and development of antidotes, and can even act as a guinea pig...

He could only think of that one person.

"So... Do you still have to tell the detective? ”

Lin Xinyi couldn't help but be entangled.
