This clue is really crucial, and it may be able to narrow down the scope of the suspects several times!

Because the announcement of eye exercises.

It is not a special announcement that can be heard everywhere.

Only in elementary school, junior high school and high school, the announcement of eye exercises will appear during class breaks.

Even colleges don’t have eye exercises.

After all.

College students are basically adults, skipping classes and surfing the Internet are commonplace, and they will not sit in the classroom and do eye exercises obediently.

The background sound of eye exercises on the call undoubtedly locks the scope of the murderer into the school.

The first to bear the brunt is undoubtedly Shude Middle School.

......

However.

As an old criminal policeman, Xu Changsheng did not immediately completely lock this clue. He tapped his fingers on the table and continued to ask.

"Shou Gou."

"Recall carefully, did you hear the sound of eye exercises when the call was connected, or..."

"Did it sound accidentally in the middle?"

"Then."

"Is the sound of eye exercises in the background clear in your impression? Or is it similar to the noise of the radio?"

It can be seen.

Xu Changsheng is trying to exclude as much as possible whether the eye exercises in the background were deliberately made by the murderer for Shou Gou to hear, or...

The eye exercises were really recorded accidentally.

As for asking whether the sound is clear or not.

Naturally, it is to judge whether the murderer behind the scenes is trying to come up with false clues to confuse the police.

Even if he is not in school, he will download the sound of eye exercises and play it during the call.

These two questions made Shou Gou frown and recall carefully for two seconds, and then answered quite affirmatively.

"Two officers."

"The sound of eye exercises on the phone was not there at the beginning, but suddenly sounded in the middle."

"At that time, I was still wondering why there was a sound of eye exercises, but I certainly didn't dare to ask more questions."

"As a lackey under that group of people, it is absolutely the first condition to save your life not to make trouble or ask random questions."

"As for whether it was a recording."

"It's definitely not. Although I was expelled from school after only attending the second year of high school, the noisy telegram sound of the school's garbage broadcast..."

"I will never forget it in my life. I can guarantee that I will never hear it wrong!"

It can be seen.

The skinny dog's mood has obviously recovered a little, and he is not as close to collapse as before.

Hearing this answer.

Xu Changsheng nodded thoughtfully, and did not avoid the skinny dog ​​who would definitely not dare to hide or lie.

Looking at Su Ming beside him, he raised his head and gestured.

"Xiao Ming, what do you think?"

"The clues of this eye exercise have pointed us to a very important direction."

"The murderer of this case is indeed very likely to be an acquaintance in the school!"

After several previous cases.

Xu Changsheng already had a clear understanding of Su Ming's reasoning ability, so he asked at this time.

Hope to integrate the most likely situation as soon as possible and lock the mastermind behind this case.

Su Ming did not answer immediately, frowning slightly helplessly.

"Brother Sheng."

"With just an eye exercise, there is really no way to draw a portrait of the suspect too surely."

"Because there is a very strange place..."

"The online person mentioned by Shougou, that is, the criminal suspect, is definitely very cautious in character from his deliberate use of a voice changer to hide and his criminal method of consciousness control."

"For such a person."

"It seems that it is not difficult to remember the time of the eye exercise that is played every day in the school?"

"Why not avoid that time period to reduce the possibility of exposure, but let Shougou hear the sound of the eye exercise."

[ 】

"Did he do it on purpose? Or did he just forget it suddenly?"

"Based on the current clues and my understanding of the suspect, I don't think I can make an accurate judgment."

"But what I can roughly determine is..."

"If the murderer is really someone from Shude Middle School, then there is a high probability that he has an independent office."

"Otherwise."

"I don't think he would dare to call and contact Shougou in an open space such as the grade office or the playground."

"Of course, the premise is that the murderer is indeed someone from Shude Middle School, otherwise all inferences have to start over."

"There are still too few clues."

Speaking of this.

Su Ming looked at Shougou, who was full of astonishment, and seemed to be shocked at how the two could judge so many details from an eye exercise, and said seriously.

"Shougou."

"Continue to recall, when you contact that person again, is there anything special?"

"For example..."

"Are there any aspects of the transaction location, transaction details, transaction process, etc. that make you confused and completely confused about its intention?"

No doubt.

Based on Su Ming's own experience.

Whether out of vigilance or to clear suspicion, a vigilant murderer like the mastermind is likely to expose more details during the transaction!

Shou Gou saw that the suspect could not be identified.

In order to ensure the safety of his daughter, he began to scratch his hair with both hands, carefully recalling the process and details of each transaction.

A full minute passed.

Seeing that Shou Gou did not speak and was still scratching his hair, Xu Changsheng frowned and then spoke.

"No other questions?"

"If you really can't think of it, then tell me how many times you have traded, respectively in..."

Hasn't finished yet.

Shou Gou suddenly raised his head, looked at Su Ming and Xu Changsheng, and spoke hastily.

"And... I remember!"

"He seems to be very familiar with the Magic City. We have traded three times in total, but the trading location he chose each time..."

"I really haven't heard of it!"

"You know, I have lived in the Magic City for more than ten years, and I am considered a half-local, but I am not familiar with a single trading location."

"Even the location of the first transaction, I still asked the elderly living nearby to find it, otherwise I really couldn't find the place!!!"

These words.

Su Ming became interested again, raised his eyebrows and looked at Shougou and asked in depth.

"Since it is so difficult to find the transaction location."

"Then I think what were the locations of the three transactions? Shougou, you should remember it very clearly, right?"

Shougou nodded immediately, and then said without hesitation.

"The first transaction was two months ago, under the stone bricks at the back door of Fulin Store, with 200 grams of high-purity Xiaobai hidden."

"The second transaction was a month ago, in the iron gate of Shengtian Textile Factory. At that time, I struggled to climb in and got 300 grams of high-purity Xiaobai."

"As for the third time."

"It was in the doghouse at the end of Hexing Alley, with a bag of candy in it, which is what you two police officers just talked about."

"The only pity is..."

"Every time he traded, he hid the things first, and then asked me to go and get them. I never had the chance to see his specific appearance."

"Of course, even if I had the opportunity at that time, I would definitely not dare to take a look."

"After all, the example of Brother Tie San is right in front of us..."

As soon as the voice fell.

Xu Changsheng tapped the table lightly, squinting his eyes and telling the story seriously.

"Old Modu people."

"Drug dealers who can choose these three places to trade must have grown up in Modu and are native locals!!!"
