The 02 box happens to be the place where Mitsuhiko is responsible for cleaning.

That's where Mitsuhiko got the tape recorder. The tape recorder was badly damaged, and it was found in a trash can when it was found, and Mitsuhiko also found some fragments of something unknown under the chair in the box.

Because there was no fatal case inside the 02 box, most of the things were kept, but because the appearance of the tape recorder was very suspicious, and it may be closely related to someone's serious injury, the police took this thing away at the time, but found nothing, and there was no information in the tape recorder.

Although the eldest lady said that the murder scene is basically kept as it is, there is no body, and some of the evidence has long been taken away by the police.

Mitsuhiko tried it and found that this thing could still be used, and the sound broadcast in it was that kind of passionate rock music, which was completely different from the antique tape recorder, and the moment the sound jumped out, he was so scared that his hand shook and almost caused a second accident, Yuan Tai and Ayumi were also startled at the time, and both glared at him, especially Yuan Tai still wanted to beat people, but in the end he endured it.

The operation of things is not very proficient, before Kurosawa Silver came, Mitsuhiko was in a hurry to test the sound, racking his brains to think about how to deal with this thing and what is the use, the smartest of the three of the three, his progress at this time actually fell to the end, which made him very unwilling, but the things in his hand were related to the first case that Ayumi came into contact with, and he couldn't help but regain his fighting spirit.

At this time, the four of them entered the search again, and Mitsuhiko vowed to find new clues.

Kurosawa Silver looked around, but he walked directly to the two computers, stretched out his hand and directly started them all, and the three members of the junior detective group were stunned.

"Brother Kurosawa, you are ......"

"Give up if you can't find anything in five minutes, or come over now and see what's different between the two computers. ”

The opening time was a little slow, but Kurosawa Silver was not in a hurry, but slowly mentioned a few words to the three of them again.

It's the equivalent of letting them play a game of finding a difference for a while.

I couldn't figure out Kurosawa's attitude, but since the hint was given, the three of them immediately took advantage of the situation.

Mitsuhiko's observation is relatively keen, and he has been to this place before, so he quickly made a discovery following Kurosawa Gin's thoughts: "Megaphone!"

"What?" Ayumi and Motota leaned over with their heads.

"Brother Kurosawa, is it a megaphone, right?" Mitsuhiko looked at Kurosawa Silver excitedly, "Each computer here is equipped with two megaphones, but the computer in front of Brother Kurosawa has only one megaphone...... The white shards I picked up under the couch belonged to the megaphone, and the secret that the murderer really wanted to hide was not in the tape recorder, but in the megaphone!"

"Clever!" Kurosawa Silver clapped his hands, "So what did the murderer do with the megaphone before?"

"The megaphone is the ...... for amplifying sound," Ayumi scratched at her hair, "Could it be that the murderer suddenly amplified his voice and scared the lady in high heels and made her fall......?"

"It's too early to tell. Kurosawa Silver smiled slightly, "It's better to take a look at the computer first." The sound of the loudspeaker is usually emitted by connecting to the computer, so if you look carefully, you may be rewarded. Special reminder, the time of the murder is on X year, X month, X day. ”

Kurosawa's words were unanimously agreed.

Kurosawa Silver stepped back from his seat, Mitsuhiko and Ayumi each occupied a computer to rummage, focusing on historical records, and Motota, who was not very proficient in computer subjects, could only hehehe, but he was not idle, but pulled Kurosawa Silver away to say that he had discovered.

"Yo Xi, it's finally my turn...... "Yuan Tai rolled up his sleeves and looked like he was going to do a big job, "Brother Kurosawa, what I found is amazing, you have to use eel rice to commend me!"

"Oh?"

Yuan Tai handed the thing to Kurosawa Silver as if offering a treasure.

It was a disc with a famous anime poster from seven years ago on it, but at this time the poster had many scratches on it, and the disc was broken in half.

"Where did you find this?"

"There. ”

Yuan Tai pointed to a desktop computer in the hall and pointed his fingers: "The tiles here are wobbly when I step on them, and I accidentally stepped on the air, and I ended up hitting that machine...... Well, on top of the host, and then it popped out like a drawer, and there was this inside!"

"Yuantai, you are too powerful......" The corners of Kurosawa's mouth hooked up, the more he looked at the things in his hand, the more satisfied he became, looking at this disc, it shouldn't be an imitation, and even the important evidence that the police didn't find back then, but I didn't expect to restart the back Yuan Tai found it by mistake, it can really be said that fate is wonderful, "Go back and invite you to have a good meal!"

"I'm the leader of the Junior Detective Corps, and of course I'm the best!" said Genta puffed out his chest proudly.

Kurosawa Silver smiled.

Holding a handful of Motota again, Kurosawa Silver took him back, and Ayumi and Mitsuhiko both had a look of frustration on their faces when they saw them come in.

"Brother Kurosawa, I'm sorry, we couldn't find any useful information......"

"There is no distinction between good and bad intelligence. Kurosawa Silver touched the heads of the two of them and chuckled, "Now that you are still young, the most important thing is to learn how to gather information and learn to experience the process, the result is not important." ”

"But ......"

"Besides, you don't necessarily find nothing. ”

"Brother Kurosawa didn't even look at what we found, how do you know we have found it?"

"Because what you don't find is the best discovery. Kurosawa Silver smiled and held up the disc that Motota had given him, "The best way to hide a tree is to hide it in the forest, and it's the same thing to hide the disc in the host." But hide the disc in the woods, and it's easy to find, you know what I mean?"

The three of them looked at each other, all at a loss.

Kurosawa Silver let Ayumi and Mitsuhiko get up, sat down on his own, and calmly began to rummage, and when it came to the historical record, he did not go to check the pages viewed line by line, but to look at the time. After reading it, he changed the channel to operate, and this time he grabbed the abnormality.

"Look here, the usage record of this machine during this period is very abnormal, do you know what that means?"

There was silence.

But this time no one came forward, and after thinking for a while, Mitsuhiko blurted out: "Someone deleted the usage record after using the computer." That's what Brother Kurosawa meant when he said that he hid CDs in the woods, right?"

"It means that although I want to hide the truth, I guess if I look carefully, I can still find another anomaly!" Ayumi was excited.

"That means I want to hide an eel, and if I hide an eel in a pile of eels, no one will find out, but I can't hide a cooked eel in a raw eel, right?" Motota shook his fist.

That can also be understood in this way. Kurosawa nodded with a smile, "So the murderer must have done something in this computer at that time, and then used a loudspeaker and a disc to assist...... Oh, I almost forgot, do you want to reason about what this disc does?"
