As everyone's eyes gathered on Tani Waterizumi, Conan and Ai Haibara stood on the edge of the room with a pale face. The last message from Thirteen phone calls sounded like a salesperson for insurance, but the message made the two shudder.

"Vodka..." Ai Haibara's words showed a hint of chill, which shocked Conan, whose pupils dilated.

Sure enough, even though the sound changed after passing through the machine, the tone was that guy.

"Is this case..." Dr. Agasa bent down and covered it with his hands, and asked in a low voice in Conan's ear.

"It is unlikely that they took the action. If they came here to get the magnetic chip, they would not leave their voice in the answering machine." Conan denied with a serious face.

"Yes, if it were them, there was no need to create a secret room." Ai Haibara agreed with Conan's judgment.

"They should have confirmed Professor Hirota's whereabouts in this way and tried to let him relax his guard."

Speaking of this, Haibara Ai tweaked his hair in his ear and showed a bad smile. This bad smile made Conan's heart tremble, and his ears began to hallucinate again. Meow Meow's voice ran around in his head.

"I think they must be anxious now. Haha, if they can't take back the magnetic chip, they will be miserable."

"If you say so, they..." Dr. Agasa looked worried.

"Well, I did the right thing to transfer the phone signal from the doctor's house to another place before. I think the people in the organization have arrived nearby now..."

......

Gu Shuiquan took the gloves handed over by the Henggou Police Officer, put them neatly, squatted down, took out the tape from the telephone, pulled out a piece of tape, checked it, and handed it to the Henggou Police Officer, signaling him to observe it as well.

"There are fingerprints on it, so let the forensic class collect evidence." Gu Shuiquan said, pointing to the conspicuous fingerprint marks on the belt that was pulled out.

"Oh, OK." Officer Henggou took the tape and looked at the bright fingerprints on the tape, took out a bag of evidence from his pocket, and carefully packed it.

“Have you bought the new tape?”

"Ah, I bought it." Police Officer Henggou quickly took the brand new tape from his subordinates and handed it to Gu Shuiquan.

Gu Shuiquan clamped the naked part of the tape with his fingertips, pulled it out with a swish, and pulled it several times in a row, and a bunch of black straps were piled on the ground.

Then, he put the tape into the telephone, fastened the telephone's microphone and turned it upside down, facing the door of the study, and covered a book.

Then, pull the tape straight outside the door, put the key on it, and then leave the key outside the door, pulling the remaining belt back into the house.

Afterwards, the three chess pieces were arranged in a triangle, with the bottom side parallel to the study door, located between the door and the telephone, and in a straight line with the two.

Finally, put the end of the remaining strap on the chess piece close to the phone, put the notebook on the chess piece, and adjust the position of the three chess pieces to get them close to the edge of the notebook.

"It's useless to do this. The power of the belt cannot pull the chess piece down." Ai Haibara said quietly with his arms around.

Gu Shuiquan glanced at her, without saying a word, silently put the three chess pieces upside down.

Ai Haibara and Conan were shocked. It turned out that this was the case. With such a simple change of detail, this method became feasible.

"Mobile phone." Gu Shuiquan stood up and said to the Henggou police officer.

"Ah, OK." Officer Henggou took the mobile phone from the policeman beside him and handed it to Gu Shuiquan.

Gu Shuiquan walked out of the study with his heavy mobile phone of his elder brother, closed the door, and dialed the number of the phone in the room.

Dingling ~

Dingling ~

...

After a few rings, no one answered the caller, and the answering machine of the phone automatically started recording, and the tape outside began to be wound into the answering machine.

Outside the study door, Gu Shuiquan was watching the key being dragged into the door bit by bit when he suddenly noticed a person coming into the corridor.

This is a young man, wearing light blue jeans and a white croaker jacket, looking handsome. He was looking at the scene in front of him with a haunted expression.

"I...it seems that I'm not here at the wrong time. I'd better come to visit Professor Hirota next time." The young man swallowed and said in a panic.

"No, you're here at the right time." Gu Shuiquan said coldly, "Come here, everyone is waiting."

Being stared at Gu Shuiquan's sharp eyes, the young man felt as if he was locked by a natural enemy, and he couldn't help but do as he said.

In the study room, the key knocked down the chess piece, and the chess piece jumped away in all directions. The notebook pressed the key underneath, and the tape was wrapped into the phone answering machine bit by bit, and finally disappeared completely.

"So that's it!" Officer Henggou exclaimed, frightening the young man at the door.

Gu Shuiquan pushed open the door of the study. The door lock had been damaged by him and Dr. Agasa. When he just demonstrated the secret room technique, he just covered the door.

"What a wonderful reasoning, Mr. Gu!" Police Officer Henggou greeted him with a warm look on his face, and then noticed that there was an extra person behind Gu Shuiquan, "Uh...who is this?"

"He should be Bai Cang who left ten messages in the answering machine, which is the prisoner in this case."

Gu Shuiquan said as he walked into the room, and placed the mobile phone in the hand of the Henggou police officer following him, and then took off his gloves.

"Hey? Mr. Shirakura? Prisoner?" Officer Henggou asked with a blank look in his face, holding his mobile phone and gloves, "What's going on?"

"You killed my husband!" Mrs. Hirota rushed to Shirakra with an angry look on her face.

"I said, wait a moment, why did you suddenly accus me of being a prisoner? I don't know what happened yet." Shirakura defended with a cold sweat on his face.

"You are Mr. Shirakura, right?" Officer Henggou asked.

"Uh...I'm indeed Shirakura, right? What happened?" Shirakura Qiang said calmly.

Officer Henggou had no choice but to tell him about Professor Hirota's death.

"The only thing I did was to leave too many messages. If I were really a prisoner, how could I come back to the scene? What evidence do you have to say that I killed?" Shirakura tried hard to defend himself.

"Uh..." Officer Henggou looked at Gu Shuiquan with help.

“…”

"He came back to get the tape. His fingerprint was on it, and he took him to identify the fingerprint." Gu Shuiquan waved his hand.

"Ah, that's right, that's it." Police Officer Henggou returned with a solemn look on his face.

"I think he should have murdered temporarily, so he was so panicked that he couldn't handle his fingerprints. Moreover, in his message, he mentioned that he was here to get photos in the magnetic film. There were so many magnetic films that he secretly took away after killing, so there shouldn't be enough time to deal with them."

Conan couldn't help but interrupt.

"So, just go to his house to check and you should find the magnetic chips."

Tani Shuizumi glanced at Conan coldly, which scared the latter, who was already worried about the Black Organization, and hid behind Dr. Agasa in awkwardly.
