Science solves cases? No, I am an immortal cultivator!

Beichuan House.

When Kitagawa Taki came back, he found that Akai Mary and Sera Masumi were there too.

"Aunt Mary, Sera, you're here!"

He stopped calling her "Auntie" and just followed the Miyano sisters in calling her "Auntie".

Akai Mary nodded: "Kitagawa, you're back just in time. I came here today to continue talking about that organization."

Upon hearing this, Kitagawa Taki sat next to the Miyano sisters.

Akai Mary asked tentatively, "Shiho, what exactly are you responsible for in the organization?"

Haibara Ai and Miyano Akemi exchanged a glance and didn't hide anything: "I'm responsible for developing APTX-4869, the drug that makes people smaller."

Akai Mary frowned and said in confusion: "That woman said it was developed by Elena."

Vermouth had always said that she wanted to let her taste the poison made by her own sister.

Huiyuan Ai shook her head and said, "My mother and the others were indeed researching and developing a drug at the time, and they were also developing Drug A, but that was not the current Drug A.

The current drug A was developed by me based on some of the research results they left behind.

It was only by chance that I discovered that Drug A has the ability to regress a person's body to a child's stage."

Sera Masumi asked excitedly, "Then, Ai, can you research an antidote?"

Although Haibara Ai is her cousin, she is still used to calling her "Ai".

"Yes." Huiyuan Ai's eyes darkened, and then she said, "But I don't have the previous experimental data now, so the research process is very slow."

Akai Mary saw hope and said, "Shiho, researching the antidote is secondary. You should pay attention to your safety. That organization will definitely spare no effort to track down your whereabouts!"

Kitagawa Taki interrupted, "Aunt Mary, don't worry about that. I will protect them."

The winery investigation is an investigation, and leaving no stone unturned would be ridiculous. He had just been drinking with Vermouth, who was in charge of the investigation.

Just wait until someone else does the investigation, and then deal with that person.

The thing that the winery has the most is traitors.

meow~

Kitagawa Taki looked down and saw that the blue and white British shorthair he bought came over and rubbed against his feet.

He leaned over and took the kitten in his arms.

"May, she likes you very much!" Haibara Ai touched the cat's head.

Beichuan Taki said as a matter of course: "I brought her back, of course."

When Haibara Ai heard this, she always felt that Kitagawa Taki was not only talking about the kitten.

"By the way, May is her name?"

"Yes what's the matter?"

"Nothing, very...good."

The name is quite casual, and it is May now.

"By the way, Kitagawa." Akai Mari's voice interrupted the two people who were petting the cat: "Can you tell us your specific ideas on dealing with that organization you mentioned last time?"

Beichuan Taki said calmly, "The key is to find the two mysterious high-ranking officials in the organization, 'that gentleman' and Rum."

As long as we find and kill these two guys, the winery will be half finished.

In addition, Kitagawa Taki is also very interested in the winery's pursuit of immortality.

Vermouth must have taken medicine, and it is very likely that it was developed by Haibara Ai's parents.

However, maintaining one's appearance is a far cry from achieving immortality.

Ai Haibara added: "'That gentleman' is the leader of the organization, and Rum is the second in command."

Then, she told the two of them the information she knew about the other members.

Akai Mary nodded slightly and fell into thought.

After a long pause, she slowly spoke, "Do you know about the case of the talented shogi player Haneda Koji 17 years ago?"

Kitagawa Taki raised his eyebrows, he knew that it was Rum who did it.

However, Haibara Ai's pupils shrank.

Akai Mary noticed that Haibara Ai was acting strangely and asked with concern: "Shiho, what's wrong with you?"

Huiyuan Ai said: "I have seen Haneda Hiroshi's name. He is on the list of users of APTX-4869!"

Mary Akai looked solemn. According to what Haibara Ai said, what Haneda Hiroshi took at that time was the original drug A.

Miyano Akemi asked the key question: "Aunt Mary, why are you asking this all of a sudden?"

"The Haneda family and ours have a long history. Your uncle was hunted down and killed by that organization 17 years ago when he went to the United States to investigate the death of Haneda Hiroshi..."

When talking about Akai Tsutomu, Akai Mary's expression was gloomy.

Masumi Sera was in even more complicated feelings, as Mary Akai rarely mentioned her father.

Miyano Akemi and Haibara Ai fell silent. No wonder Akai Mary hated the Black Organization so much.

Beichuan Taki broke the deadlock: "Then we can start with this case. As far as I know, this was done by Rum."

"what?"

Everyone in the room looked at Kitagawa Taki in shock.

"I learned this from Vermouth."

Kitagawa Taki put the blame on Vermouth without hesitation.

The Miyano sisters were relieved.

But Akai Mari was even more confused: "Vermouth? That woman??"

Huiyuan Ai helped explain: "Aunt Mary, Beichuan has reached a cooperation with Vermouth. She... let me go once before."

"Is that woman trustworthy?" Akai Mary still frowned.

Since Vermouth let Miyano Shiho go, it means that she knows the effect of drug A.

Then her appearance was most likely not an accident, but intentional!

What on earth was that woman going to do?

Beichuan Taki knew that this woman was very suspicious, so he comforted her, "Don't worry! I can guarantee that she is not lying."

Mary Akai temporarily suppressed the doubts in her heart and nodded hesitantly. She could only attribute this to Kitagawa Taki's magical ability.

"Now that we know it was Rum who did this, maybe we can find out something new." Akai Mari stood up and said, "Akimi, Shiho, and Kitagawa, we're going back today!"

The two men saw that Akai Mari was anxious and did not try to keep her.

Akai Mary took Sera Masumi out of the house.

When the two of them got on their motorcycle and were about to leave.

Kitagawa Taki chased out and called out to the two of them.

"Aunt Mary, could you come over here for a moment?"

Mary Akai took off her helmet, jumped out of the car, and followed Kitagawa Taki to the side.

"Kitagawa, is there anything else?" Akai Mary glanced at Sera Masumi in the distance, curious about what Kitagawa Taki was hiding from her.

Beichuan Taki said seriously: "Aunt Mary, if you catch a cold or have a fever, remember to tell me."

"Ok?"

"This matter is very important, it concerns the antidote!" Kitagawa Taki emphasized again.

Mary Akai was even more confused. Is there any connection between the cold and the antidote?

"Beichuan, please speak clearly!"

Beichuan Taki didn't intend to explain: "Anyway, just remember to tell me, and you'll know when the time comes."

After saying that, he went back to the house on his own, which was not at all like the attitude he showed to his elders.

Mary Akai was so angry that her teeth were itching. She was always calm, but she was broken down again and again by Kitagawa Taki.
