In Conan, people have a brain option system

Masumi Sera has been checking the browsing history of the browser on Koizumi Kunio's computer, as well as the program code.

Trying to use these aspects to understand the specific functions of the software they developed.

It's a pity, as Kunio Furuzumi said.

Even he and Ryo Kawasaki, who were responsible for the development, knew only a little about this software.

Not to mention the layman Sera Masumi.

‘None of the people targeted by the organization has a simple identity. ’

‘The other party is either a defected member, an agent, or someone whose personal ability is outstanding enough to threaten the organization. ’

‘It’s understandable that Ryo Kawasaki was silenced after completing the software, but what kind of energy did Akikawa Ryoko have that allowed her to be hunted by the organization for nearly ten years? ’

Sera Masumi was thinking about these things in his mind while using Koizumi Kunio's computer.

Unfortunately, she had too little relevant information.

Akikawa Kyousuke, who has the closest relationship with Akikawa Ryoko, basically knows nothing.

‘You can also contact Okino Yoko appropriately in the future. Speaking of which, I still don’t know whether her father’s death has anything to do with the organization. ’

'In addition, regarding the car accident case and Akikawa Kongsuke, I always felt that something was wrong, but I never figured it out.'

'However, this time, as long as the murderer of the car accident can be caught, all the truth will be revealed. ’

Just as Sera Masumi was thinking in her mind, Conan's voice suddenly sounded from the side:

"Ms. Sera, have you found anything in your investigation?"

"No, I don't understand."

Sera Masumi shook her head, and a trace of regret appeared on the girl's delicate cheeks.

"We don't know yet whether people in the organization know that Mr. Koizumi was taken away."

"If they didn't know, they would have informed the place and time of the transaction as originally planned."

"If they knew about it, just like Miss Sera said, they would send someone to sneak into the hotel and steal the computer."

"There must be someone inside the room to answer the phone, but to be on the safe side, it is best for another person to stay outside the hotel, and the person in the room must have a voice changer."

Conan said, then took out a badge with the Young Detective Corps' logo from his pocket and handed it to Sera Masumi.

This is a communicator designed by Dr. Ali for the members of the Young Detective Team.

In addition to wireless intercom, it also has a positioning function.

Conan can see the location of the badge through his tracking glasses.

"So Sera-san, just wait outside. I will use this detective team badge to contact Sera-san at that time."

Sera Masumi took the badge from Conan's hand and pinned it on the inside of the collar of her coat.

However, she did not leave directly after taking the badge, but extended her hand to Conan again.

Conan looked at Sera Masumi with some confusion, and then heard Sera Masumi say:

"Boy, it's too dangerous for you to stay in the room. If the mission fails and the other party sees your face, it will inevitably arouse suspicion."

"I pride myself on being pretty good at it. It should be much safer than if you stay in the room, kid."

"So, give me the voice changer."

Conan knew that Sera Masumi was telling the truth, so he took off his bow-tie voice changer and put it into Sera Masumi's hand without pushing too much.

"Boy, what can you do to protect yourself now?"

Sera Masumi took the bow-tie voice changer and continued to ask.

"That's all, the watch anesthesia gun, telescopic sling, football injection valve and foot strength-enhancing shoes."

"Who would have thought that something like this would happen to me this time when I came to the hot springs, so I didn't prepare many things."

Conan said helplessly.

If he had known it in advance, he could have asked Dr. Ali to make many powerful props for him.

"No, I think wherever you show up, kid, there will be murders."

Sera Masumi joked.

Conan: "?"

Faced with Sera Masumi's "rumors", a big question mark appeared above Conan's head.

He immediately waved his hand and left Koizumi Kunio's room.

"I'm leaving first, please be safe, Miss Sera."

After Sera Masumi also said goodbye to Conan, she then set her sights on the wall in the room.

Wherever she could see, there were several small holes.

Sera Masumi has confirmed the material of the wallpaper before, and it is a multi-layer composite wallpaper.

The walls of Japanese rooms are usually covered with wallpaper with sound insulation effect, and the rooms in Kosenan are no exception.

This is one of the most commonly used wallpaper materials in Japanese apartments.

The advantage is that it has good sound insulation effect and also has good decorative properties.

The disadvantage is that its strength is low and it can be broken easily.

‘Kunio Koizumi said that the photos of him and Ryo Kawasaki’s family were nailed to the wall of the room after they woke up. ’

'It seems that these holes were left on the wall by the nails used to attach photos at that time. ’

‘Since the other party was able to do this, it means that the other party was able to get the room key of Kunizumi Kunou’s room without anyone noticing. ’

‘The possibility of the other party entering the room directly to get the computer must also be taken into account. ’

Masumi Sera calculated her current position and the time it would take to rush to the door of the room.

‘There will be a sound when the door is opened, so this will give me time to react. ’

‘During the time when the other party opens the door, I must rush to the door as fast as possible and not give the other party a chance to react. ’

Masumi Sera confirmed that the other party’s reaction time after seeing her would not exceed one second at most.

So she tensed up and sat at the desk, waiting for time to pass.

Under Masumi Sera’s highly concentrated state, the passage of time began to become unusually slow.

Time passed by minute by minute, and finally reached 0 o’clock the next day.

Masumi Sera waited for more than an hour.

However, there was no movement from the phone in the room or from Kunio Koizumi’s door.

Even though Masumi Sera’s physical fitness is several times stronger than that of ordinary people.

But like now, she was in a tense state for a long time, and she still felt mentally exhausted.

"Ms. Sera, how is the situation over there?"

Suddenly, Conan's voice rang out from the badge of the Junior Detective League on the inside of Sera Masumi's collar.

It seemed that Conan was also a little impatient because of the long wait.

"No contact was received, and no one came directly into the room."

Sera Masumi lowered her voice as much as possible, pressed the communication button, and said to Conan.

However, as soon as she finished speaking, the phone rang in the room.
