On the other side, No. 22, Yoneka-cho 2-chome.

After sending off the three children of the Young Detective Corps, Conan did not return to the office, but followed Dr. Agasa's house.

Basement, kitchen, bedroom, bathroom.

After seeing Sydney’s cat bowl full of cat food.

Conan muttered reluctantly:

"I made breakfast, took a shower, changed my clothes and fed the cat, and now I'm out again. Damn it... I can't figure out why brother Gengyi came back before us."

"I think you are addicted to detectives again..."

Because she knew the general whereabouts of Ye Gengyi, Haiyuan Ai didn't panic. The reason why she didn't say anything was to not distract Conan's attention, so as to find out as soon as possible what kind of information this detective boy was investigating the organization.

He yawned, indicating that he was going to take a shower.

She walked into the bathroom, deliberately made the sound of turning the lock, and then put her ear against the door to listen to what was going on in the living room.

As expected.

Conan really didn't waste a second and immediately grabbed Dr. A Li and walked toward the bedroom.

I know it’s not enough just to remind you that Brother Yi is not here, you will definitely discuss it in private without telling me...

The door of the bathroom quietly opened a gap, revealing half of Hui Yuan Ai's face that was secretly observing.

She followed quietly outside the bedroom and eavesdropped.

in the room.

After Conan turned on the computer, he quickly entered a text in the search bar.

"Shinichi, why are you looking up the telephone area code of Tottori Prefecture?" Dr. Agasa asked doubtfully, "Is there any problem here?"

"You should still remember the case that happened in Okinawa that I mentioned in the car yesterday," Conan said with a serious face. "At that time, in the office of the Naha Police Station, Mr. Motoyama dialed a number on his mobile phone.

I really care who he calls..."

"But Mr. Motoyama is dead," Dr. Ali gave an analysis: "If it is an important number, as Gengyi said, the police will definitely investigate it carefully..."

"Yes," Conan nodded: "So now I finally understand that what really matters to me is not who he called, but the key tone that the phone made when they pressed the number!"

"Press, key tone?"

"That's right! Just in the early morning, when Officer Yamamura called his grandmother who lives in Tottori Prefecture, I finally figured it out..."

The corner of Conan's mouth curled up, "The reason why it feels familiar to me is because the area codes of the phone numbers they pressed are all 0858!"

"0858? Shinichi, what on earth are you talking about?" Dr. Ari continued to be confused.

"In Tottori Prefecture, the only ones with the telephone area code 0858 are Kurayoshi and Hatou,"

Conan controlled the mouse to circle these two names:

"Apart from them, the only other person who gave me the same feeling was the email that Belmode sent to her companion after taking me, who was under anesthesia, and driving into the woods during the dock incident. At that time,

I had already woken up, so I heard it clearly, and the button sound was very similar to this one!"

"What?!" Dr. Ali was shocked.

"The other party is definitely not a small role. Doctor, you should have heard it through the bug installed on me. What the woman subconsciously blurted out when replying to the email was..."

Conan looked serious:

"ok, boss..."

"It's difficult. Could it be that this number is..." Dr. Ali was shocked when he heard this.

Valley jealousy

It was Belmod who actually leaked it to him. Did these two people never consider the consequences of doing so?

No, it should be said that Belmode did not kill Edogawa. Their identity as 'godmother and son' is indeed very questionable!

Hui Yuan Ai hid outside the door and frowned unconsciously.

She forcibly resisted conveying this information to Ye Gengyi via email or phone. After taking a few deep breaths silently, she continued to eavesdrop on the conversation in the room...

"If I guess correctly, if I continue to investigate the number behind 0858, I will definitely be able to find the boss behind the organization. By then, their names and hiding places will be exposed one by one..."

Conan said:

"Also... at that time, the woman did not reply directly to the email. Especially at that critical moment, she actually re-entered the other party's number. I guess they must have received training similar to immediately erasing call records...

Ha, this kind of habit formed by muscle memory is usually difficult to eliminate. It will be beneficial to us if we have this information and pay attention to observation. If there is really that kind of guy lurking around us..."

Speaking of this, he paused, and the figure of Ye Gengyi subconsciously appeared in his mind.

Uh... According to Brother Geng.

Does he have the ability to delete instructions after making a phone call or sending an email?

It seems not...

Sweat... I'll observe it quietly next time.

"Shinichi, what's wrong with you?" Dr. Ari noticed that a certain detective was distracted.

"No, it's nothing."

Conan shook his head. After telling that, he temporarily suppressed the thought that he might be beaten. He took out his mobile phone from his pocket, pressed the numbers '0858', and brought back the topic:

"Actually, these are the only four numbers that give me this feeling, and there seems to be something wrong with this '0858'..."

"How many digits do all the numbers add up to?" Dr. Ali asked.

"8 or 9 digits," Conan kept testing, "and the front and back must be connected together."

"Is it possible that it was the sound she made when pressing English letters," Dr. Ali analyzed. "After all, if it wasn't for the convenience of memory, and the email address registered with her own mobile phone number, it might not be necessary to add letters."

"I have thought about this, but the letters and symbols corresponding to 0858 on the keyboard are comma and 'tjt' respectively. If they are all letters, it can be explained, but if the comma is placed first, there is no way.

Register..."

Conan held his chin with one hand and said helplessly:

"In retrospect, when the woman was sending the email, her expression seemed very lonely, and she seemed to be missing something. It was really confusing..."

"Nostalgia for...nostalgia?"

Dr. Ari hesitated, "Shinichi, are you okay?"

"Oh, don't worry, doctor, if I think of anything I will tell you right away!"

Conan quickly comforted him: "The person we are facing this time is probably the boss behind them. If I don't have complete preparations, I will not act rashly and put everyone in danger..."

"That's good..." Dr. Ali breathed a sigh of relief.

"By the way, there's one more thing," Conan added: "I don't need to tell you, Doctor, you should also know about it. Don't tell Haiyuan and Brother Geng about this first."

"Well, don't worry." Dr. Ali nodded, "I will help hide it."

outside the door.

Hui Yuan Ai quietly moved away, cursing in his heart:
Chapter completed!
