Duanmu Xuan ignored Gray Yuan's sorrow, raised the hand in his hand to express his meaning, and walked directly to Conan who was still talking carefully.

"This seems to be a recorded phone call, listening to the recording inside should be able to find clues."

"Huh?" Henggou Shenwu glanced at Duanmu Xuan strangely, and also recognized Duanmu Xuan, "You are Xiao Xuan?" Also the child who was by Mr. Maori's side last time? ”

"Yes, it's me, Officer Henggou, long time no see." Duanmu Xuan nodded, and then said straight to the point, "Officer Henggou, let's listen to the recording on the phone first, I don't have much time." ”

"Running out of time?" Yokozo Sango and Conan were a little confused.

"Oh~ This gentleman said that he would find the murderer in ten minutes, of course he didn't have much time, and there were still 9 minutes and 40 seconds." Gray Yuan Ai on the side also walked over, thinking about deliberately delaying Duanmu Xuan's time, although she thought that even if she gave Duanmu Xuan ten minutes, it would be impossible to find the murderer, but she was cautious and still planned to make some trouble for Duanmu Xuan.

She looked at Duanmu Xuan with a smile in her eyes, as if she had seen the picture of waiting for Duanmu Xuan to lose and reluctantly sending herself to her sister.

Regarding Duanmu Xuan's words just now, she just thought that Duanmu Xuan was able to do it in front of her, and solve the case in ten minutes? Are you kidding? If the case had this efficiency, it is estimated that no one in the world would dare to commit a crime, even an ordinary case would not be able to solve the case in ten minutes, not to mention this kind of closed room homicide, the crime of closed room homicide is a representative of high-IQ crime, if only it was so easy to see through.

"Haha, Xiao Xuan, don't make trouble, this is not a place for children to joke." After listening to Gray Yuan's words, Henggou Sanwu immediately laughed, what are you kidding, solve the case in ten minutes, is this a playhouse? Originally, his impression of Duanmu Xuan was quite good, he looked very sensible and mature, but now, he found out that he was wrong, very wrong, it turned out that this kid is also the kind of little ghost who likes to be in the limelight.

"Xuan, is it April Fool's Day? Ten minutes to solve the case, how is it possible. Even Conan, who admired Duanmu Xuan's reasoning ability, couldn't help laughing, what is ten minutes enough? It takes more than 10 minutes to inspect the scene.

"Hey, Xuan, stop kidding, pay attention to Mrs. Hirota's emotions." Dr. Asa leaned over to Duanmuxuan and quietly pointed to the middle-aged woman behind him, Professor Hirota's wife.

At this time, Professor Hirota's wife was looking at Duanmu Xuan angrily, after all, her husband was dead, but Duanmu Xuan was still here to joke about this kind of thing, and everyone would be angry.

Duanmu Xuan glanced at Conan and them, did not speak, but raised his hand, and looked at the watch in his hand, "There are still 9 minutes." ”

"Hey, hey, Xuan, are you serious?" Conan looked at Duanmu Xuan in surprise.

Yokogou Sango frowned, what does this little ghost mean? Do you think you are the reincarnation of Sherlock Holmes?

"Please get out! You're not welcome here! Yokogou Sango was just unhappy, and Professor Hirota's wife on the side said unceremoniously, originally her husband died, she felt uncomfortable, and there were still people here making fun of her husband, she felt that she couldn't bear it anymore, in her opinion, Duanmu Xuan was just a child who was ashamed of his words.

Duanmu Xuan frowned, glanced at Professor Hirota's wife, did not speak, but took out a pack of tissues from his arms, took out one, wrapped his hands, turned over the phone on the ground, and then pressed the message playback Jian, "I have seen through the murderer's modus operandi, as long as I listen to the recording of the phone, I can confirm my reasoning."

"Saw through the murderer's modus operandi, so quickly?" Conan was taken aback, he could see that Duanmu Xuan was serious.

Henggou Shenwu's brows furrowed even deeper, he didn't believe Duanmu Xuan's words at all, if it weren't for the fact that the relationship between Duanmu Xuan and Maori Kogoro seemed to be good last time, he would have kicked Duanmu Xuan out long ago, of course, Duanmu Xuan looked professional, wrapped his hands in a tissue, and the reason why he didn't directly touch the evidence was also among them.

Professor Hirota's wife hated Duanmu Xuan even more, and was about to have a seizure when a message on the phone rang.

"There are 13 messages in total." It's the statistical sound of the phone.

"Moximoxi, I'm Bai Cang, Professor Hirota, let's make an appointment for the evening." A young male voice came over the phone.

"I'm Morioka, what time would I be better to come over tonight." Next was the voice of a middle-aged man.

"Moxi Moxi, I'm Bai Cang, Professor Hirota, I can't seem to go at night, so I'd better visit you tomorrow." It was the white voice again.

"Moxi Moxi, I'm Bai Cang, Professor Hirota, I remember, I have something to do tomorrow, so let's do it tonight, what time are you free."

"Moxi Moxi, I'm Bai Cang, Professor Hirota, are you there?"

"Okay, I know who the murderer is." Hearing this, Duanmu Xuan directly pressed the phone, he didn't care about the content at all, he played back these messages, just to find an excuse for the reasoning he saw in the anime.

"Xuan, do you know the murderer?" Conan looked at Duanmu Xuan in shock.

"Little ghost, this is not a place for you to mess around, hurry up and get out of here." Henggou frowned, looking at Duanmu Xuan, and he couldn't help it now.

There were still 5 minutes, Duanmu Xuan ignored him, but glanced at the watch in his hand.

"The murderer is that Bai Cang, and I also have evidence about his crime." He said straight to the point.

"Little ghost, don't be ashamed here, Bai Cang is one of my husband's most proud disciples, how can he be a murderer." Professor Hirota's wife looked at Duanmu Xuan in disgust.

Henggou Shenwu looked at Duanmu Xuan's eyes with a hint of disgust.

"He is the murderer, and his modus operandi was done through this recorded phone call." There were still 4 minutes and 30 seconds, Duanmu Xuan glanced at his watch, ignoring Henggou and comprehending them.

He first killed Professor Hirota in the room, put the message phone on the ground, and then pulled out the tape in the message phone, and then held the book on top of these chess pieces on the ground, passed through these chess pieces with the tape, took the key, walked outside the door, calculated the distance, and then used the tape through the keyhole, and then called the telephone outside the door to leave a message, and the tape would naturally be recycled, and when passing through these chess pieces, the key hit the chess, and then the book on it fell and pressed the key, In the end, the tape was completely recovered, which led to the murder in the closed room. ”

In order to save time, Duanmu Xuan said very concisely, but he simply explained the modus operandi, he knew that Henggou Sango and Conan were not stupid, and they should be able to understand what he said.
