Conan: I'm a zaibatsu in Tokyo

night.

Zheng Yi lay on the sofa in the living room reading a book, glancing towards the door every now and then.

Like a stay-at-home husband waiting for his wife to come home.

He was reading the manuscripts by Takeda and Matsumura.

The two of them only wrote for a week, and there wasn't much content in it at all; they had only read the beginning.

"Sigh! I've been forced to become a eunuch." Zheng Yi sighed.

He placed the two manuscripts on the table, the papers making a slight sound as they touched the surface.

The sound of footsteps came from far to near.

Ai walked up to Masakazu and said, "I have something to tell you."

"What is it?" Zheng Yi asked.

Ai said, "Sera Masumi is testing me again."

"Oh, that's normal."

Shoichi patted Ai's head. Ai, who was already used to it, did not resist at all, which made Shoichi feel that something was missing.

“It’s normal for Sera Masumi to test you since Conan’s identity has been discovered,” Masakazu said.

Ai nodded.

That foolish detective, I knew he couldn't be trusted.

I just don't know why Xiaolan has been fooled by him until now.

Knowing the reason why Sera Masumi was testing her again, Ai no longer cared.

Just as she was about to go back to her room to create, Zheng Yi called her back.

"Wait, Ai, I also have something very important to tell you," Masakazu said.

"what's up?"

Ai looked at Masakazu without taking it seriously.

I don't think Zheng Yi can do anything serious.

She even felt like running away, afraid that Zheng Yi would make her work overtime again.

But Zheng Yi didn't say anything excessive.

He walked over and hugged Ai, leaving Ai completely bewildered.

Even Ai Haibara is finding it a little hard to get used to Masakazu's gentleness.

Masakazu stroked Ai's head and said, "Didn't you always tell me that you wanted a little sister?"

"When did I say that?" Ai asked, puzzled.

She only needs one older sister.

"Actually, you've had it for a long time, but I didn't know how to tell you." Zheng Yi looked conflicted.

Ai: ?
Thankfully, it wasn't her niece.

With her hands on her hips, she asked, "So, you kidnapped another little girl?"

"Where is she? Are you keeping her on the side?"

Zheng Yi said with some dissatisfaction, "The way you're talking makes it sound like I'm keeping a mistress."

Ai stood with her hands on her hips, silently watching Masakazu.

Do you think you can just pick up any little girl and expect me to be her older sister?

Masakazu continued, "Sera Masumi has a mother."

Ai: ?
She suspected that Zheng Yi had taken the wrong medicine today.

The way this topic has shifted is so strange.

I was just talking about how I have a new little sister, and then I turned around and said that Sera Masumi has a mother.

That's strange. Without a mother, where did Sera Masumi come from?
Ai grabbed Shoichi's arm and made him squat down.

She touched Zheng Yi's forehead with her little hand, and then touched her own.

He didn't have a fever, but he started talking nonsense.

Ai said with ill intent, "You're talking strangely today. I suspect you're sick."

"Why don't you lie down on the lab table and let me examine your body?"

Shoichi flicked Ai's forehead.

Masakazu said, "I investigated Sera Masumi and found that she doesn't have a younger sister at all."

"Huh?" Ai frowned in confusion.

There really was a little girl next to her.

Moreover, it didn't seem like a child who had been abducted by Sera Masumi.

Masakazu poked Ai's cheek and asked, "Don't you think Sera Masumi's younger sister looks a lot like you?"

"You mean, she's actually my sister?" Ai blurted out.

"Impossible! Absolutely impossible!" Ai exclaimed.

The time doesn't match up.

She couldn't possibly have a younger sister that age.

Ai said, "They just look alike. Doesn't the phantom thief you keep look a lot like Shinichi Kudo? Are they brothers?"

“Who says otherwise?” Zheng Yi said, tossing the investigation report on the table to Xiao Ai.

"I've found out that Shinichi Kudo and Kaito Kuroba are actually cousins."

"?"

Ai's head was full of questions.

She casually gave an example, and they actually became cousins?

She stared in disbelief at what Zheng Yi was investigating, speechless for a moment.

"Why did you suddenly start investigating the relationship between Shinichi Kudo and Kaito Kuroba?" Ai couldn't help but ask.

“Because I found out about your relationship with Sera Masumi,” Masakazu said.

Shoichi looked at Ai and said, "Conan told me that Sera Masumi knows his identity and is asking him for the antidote."

"So, I investigated Sera Masumi and learned about her family situation."

"So I suspect that her sister was actually shrunk because her mother took drug A."

"Huh?" Ai lowered her head and thought, "But Shinichi and I both turned into elementary school students, while she looks like a middle school student."

"Perhaps it's because she's older," Zheng Yi said.

Xiao Ai frowned.

Zheng Yi poked Ai's face again, disrupting her thoughts.

"Because she looks like you, I did some further investigation and found out that she is your aunt."

"?"

Ai looked at Shoichi and blinked.

Her brilliant mind failed to grasp the meaning of the sentence immediately.

“Akai Mary, your aunt.”

Masaru handed Ai a detailed investigation report.

This is something that Masakazu had collected a long time ago, because Akai Mary was in England before, so collecting these things was quite troublesome.

I only recently found such a comprehensive search.

While Ai was looking at the documents, Masakazu leaned close to her face and whispered:

“Since she’s your aunt, how about we bring her to live with us? It’ll be a good opportunity for us to show our filial piety.”

Masakazuki got closer and closer, almost touching Ai's face.

Ai placed the back of her hand against her cheek, then pushed Shoichi's face with her palm, creating distance between them.

She looked into Zheng Yi's eyes.

I have a feeling that Zheng Yi has ill intentions.

"Let me have some peace and quiet first," Ai said.

"it is good."

Ai looked at the information above.

This family seems quite complicated; the three siblings have three different surnames.

Ok?
When Ai Haibara saw the name Shuichi Akai, she paused for a moment.

"Akai Shuichi?"

"Hmm." Zheng Yi looked in the direction Ai was pointing and said, "An FBI member, and also your sister's ex-boyfriend."

Xiao Ai swallowed.

It took me a long time to process this news.

So, they're cousins? Then what happened before...?

Ai's mind was in a mess.

Are these documents of yours genuine?

Can I show you fake documents?

Ai looked into Shoichi's eyes, stared for a while, and said, "I'm going to talk to my sister about it."

When a whole family of relatives suddenly appeared, Xiao Ai's mind went blank. She wasn't prepared at all.

I was just thinking of living a good life with my sister, but then another family of relatives came along.

“Your sister went on a business trip,” Zheng Yi said.

Xiao Ai paused in her steps.

He stared into Zheng Yi's eyes, unmoving.

stare!
Masakazu leisurely poured himself a glass of warm water, took a sip, and then handed it to Ai, saying, "Would you like some?"

Xiao Ai remained silent, only staring intently at Zheng Yi.

“It’s normal to travel for work or business.” Zheng Yi bit his cup.

It's not like I specifically sent Akemi Miyano on a business trip.

He said, "You should blame your sister more; she went on a business trip without telling you."

"Humph!"

Xiao Ai was too lazy to listen to Zheng Yi's nonsense.

Zheng Yi put down his water glass and said, "Let's get back to our previous topic. How about we bring your aunt to stay with us?"

"No!" Ai Haibara objected.

She was fairly familiar with Sera Masumi because they were classmates, but she didn't know that aunt at all.

Moreover, after switching relationships with Sera Masumi, getting along became a troublesome matter.

Most importantly, Ai felt that Shoichi's gaze was very strange.

"Do you really have some kind of special fetish?" Ai asked.

"No."

"Then why are you so keen on having that little girl stay at your house?" Ai asked.

Zheng Yi blinked.

"I wasn't particularly enthusiastic about it; I just mentioned it a couple of times."

Ai pouted: "Why don't you look in the mirror and see how lewd your expression is?"

"Have it?"

Zheng Yi actually went to the mirror and looked at himself.

He imagined bringing Akai Mary home and living with Ai, and tried to regain his composure.

“It looks perfectly normal,” Zheng Yi said.

Ai Haibara is just too prejudiced against herself.

It was a perfectly normal expression.

Ai followed behind Shoichi and felt a chill run down her spine when she saw Shoichi's reflection in the mirror.

Uh ~
As soon as he turned around, he flashed a set of white teeth at Ai.

Ai unconsciously took a step back.

But Shoichi did not do anything bad to Ai.

Instead, she curled Ai's head up and said with a curious look, "Your family's constitution is quite special."

He pinched Ai's cheek and said, "The organization killed so many people with Drug A, but Conan was the only exception."

"When it came to your family, the two people who took drug A both became young again."

Ai kept a straight face, letting Shoichi's hand wrap around her head.

"So what?"

Zheng Yi said with great interest, "Then what do you think about letting your sister take the A drug to shrink?"

"impossible!"

Ai reacted strongly, shoving Masakazu away.

Zheng Yi took several steps back in coordination, pretending that he almost fell.

“I’m not having your sister take the current A drug, but the one that’s been stabilized,” Zheng Yi said. “It can stabilize her shrinking size, and it’s not the poison kind.”

"That won't work either." Ai looked at Masakazu warily.

She questioned Zheng Yi, "Why do you have such thoughts?"

Zheng blinked and said, "I was just worried you wouldn't be able to figure out an antidote, so I'm giving you another approach."

“I don’t need that line of thinking,” Ai said.

Not to mention that my antidote has made progress and can temporarily restore people's health.

Even if an antidote can't be developed, I can just grow up slowly and won't need my sister to accompany me.

Masayuki saw through Ai's thoughts and his expression became very serious.

"How can you be so selfish?"

"Huh?" Ai's eyes widened.

If I don't satisfy your lolicon desires, am I being selfish?
You don't think I don't know your filthy thoughts, do you?

"Even if you don't think about yourself, think about Conan and Ran at least," Masakazu said.

"Conan spent so much money, and Ran is your classmate. Can you bear to let these childhood sweethearts continue to live like this?"

Masayuki pointed at Ai and said, "If you can't develop an antidote, but instead develop a harmless drug A, so that Ran can also shrink, it would be good if the two childhood friends could grow up again!"

"You can't just think about yourself, you're too selfish."

Xiao Ai was speechless.

Shoichi was still saying to Ai, "And think about your sister."

"If you can't find an antidote, then there will be a significant age difference between you and your sister."

"Can you bear to see your sister die of old age?"

"This……"

Ai began to think.

Although Zheng Yi's initial intentions were bad, there was some truth to what he said.

Whenever I think of my sister, who is sick and bedridden, my heart feels like it's being clenched.

Zheng pulled Ai to his side, patted her on the shoulder, and said, "See, what I said makes some sense."

“It makes no sense at all,” Ai said.

"Don't think I don't know what you're thinking?"

Ai didn't want to discuss this topic with Shoichi anymore.

The conversation started with a relative who suddenly appeared, and then moved on to birth, aging, illness, and death.

She looked at Masakazu and said, "Don't tell Sera Masumi that I'm her older sister."

"I'm not mentally prepared yet. At least let me talk to my sister."

Zheng Yi nodded: "No problem. You and your sister can also discuss what I said."

"Don't even think about it," Ai yelled at Masakazu.

She kicked Zheng Yi with her toes.

Zheng Yi rubbed his knees, watching Ai's departing figure, unsure if she had even taken his words to heart.

When doing anything, you should make a plan (1, 2, 3).

Zheng Yi felt that his new plan was very good.

Ai refused so decisively, without even thinking about it.

At least ask Akemi Miyano.

What if she's willing?

I want to relive the feeling of childhood and grow up slowly with my younger sister.

He took out his phone and called Conan.

"Hey, Zheng Yi, what brings you here so late?"

"Can you accept growing up with Xiaolan again?"

"Ok?"

Conan, who was in the restroom, was stunned for a moment, not understanding what Shoichi meant.

"Brother Zhengyi, could you say that again?"

"Never mind, it's nothing." Zheng Yi shook his head.

Let's not think about things that are so far away.

Zheng Yi changed the subject: "Didn't I invite a lot of writers to write my autobiography?"

"I would like to invite Mr. Yusaku Kudo to come and take a look, to give some guidance to those writers, and to see if they have put their heart into their writing."

“I am not familiar with other people, so I can only trust Mr. Kudo Yusaku. I would like to ask him to take a look when he has time.”

Conan readily agreed on behalf of his elderly father.

"No problem, I'll tell him."

After receiving the promise, Zheng Yi nodded and said to Conan:

"By the way, Conan, you can come along too. You know me well, so you can check what they wrote and see if there are any mistakes."

"No problem." Conan nodded.

As their conversation was about to end, Conan suddenly asked, "Brother Zhengyi, is the research on the antidote not going too well?" (End of Chapter)
