After 100,000 simulated crimes, I became an ace detective.

Eye exercises?

Thin Dog suddenly recalled this special clue.

Su Ming and Xu Changsheng looked at each other in tacit understanding, their eyes twinkling.

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

Because of the announcement of eye exercises.

This is not a special broadcast that can be heard everywhere.

Only in elementary schools, junior high schools and high schools, eye exercises are broadcast during recess.

Even universities don’t have eye exercises anymore.

after all.

College students are basically adults. It is common for them to skip classes and surf the Internet, but they will not just sit in the classroom and do eye exercises.

Eye exercises were heard in the background of the call, which undoubtedly locked the murderer in the school.

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

......

but.

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

"Skinny dog."

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

"The sound that came out unexpectedly in the middle of the journey?"

"Then."

"Does the sound of the eye exercises in the background sound clear to you? Or is it similar to the noise of a radio broadcast?"

As can be seen.

Xu Changsheng was trying his best to rule out whether the sound of eye exercises in the background was deliberately made by the murderer so that the thin dog could hear it, or was it...

It was really an accident that I included eye exercises.

As for asking whether the sound is clear or not.

Naturally, it was to determine whether the murderer behind the scenes was trying to confuse the police with false clues.

Even if you are not at school, you can download the sounds of eye exercises and play them during phone calls.

These two questions made Skinny Gou frown and think carefully for two seconds before he answered with certainty.

"Two officers."

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

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

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

"As for whether it was a recording played."

"That's definitely not the case. Although I was dropped out of school after I was only in my second year of high school, the noisy telegraph sound of the school's garbage broadcast..."

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

As can be seen.

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

Hear this answer.

Xu Changsheng nodded thoughtfully, not shying away from the thin dog who would definitely not dare to hide anything or lie.

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

"Xiao Ming, what do you think?"

"This clue about eye exercises has pointed us in a very important direction."

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

After several previous cases.

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

We hope to put together the most likely scenario as soon as possible and identify the man behind this case.

Su Ming did not answer immediately, and frowned slightly helplessly.

"Brother Sheng."

"With just one eye exercise, there is really no way to paint a portrait of the suspect with too much certainty."

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

"The person mentioned by Shougou, the suspect, is definitely very cautious in character, judging from his deliberate use of a voice changer to hide his crime and his conscious control of the crime."

"For this kind of person."

"It seems that it is not difficult to remember the time for eye exercises that are broadcast every day in school?"

"Then why not avoid that time period to reduce the possibility of your own exposure, but let the thin dog hear the sound of eye exercises."

"Did you do it on purpose? Or did you just forget it all of a sudden?"

"Only based on the current clues and understanding of the suspect, I don't think we 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."

"if not."

"I don't think he dares to call and communicate with Shougou like this in an open space such as the senior office or the playground."

"Of course, the premise is that the murderer is indeed from Shude Middle School, otherwise all inferences will have to be made again."

"There are still too few clues."

Speaking of it.

Su Ming looked at the astonished thin dog, who seemed to be shocked at how the two of them could judge so many details from just an eye exercise, and said seriously.

"Skinny dog."

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

"Just like..."

"Is there anything about the transaction location, transaction details, transaction process, etc. that makes you confused and you don't understand the intention at all?"

no doubt.

Judging from Su Ming's own experience.

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

Shougou saw that he could not identify the suspect.

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 the thin dog, he didn't say anything and was still scratching his hair. This made Xu Changsheng frown and then spoke out.

"Are there any other questions?"

"If you really can't think of anything, then tell me how many times you have traded in total, and they were..."

Not finished yet.

The thin dog suddenly raised his head, looked at Su Ming and Xu Changsheng, and spoke hastily.

"And...I remembered!"

"He seems to be very familiar with Magic City. We have traded three times in total, but the place he chooses to trade 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 half a local, but I am not familiar with any trading place."

“Even for the location of my first transaction, I had to ask the elderly people living nearby to find it. Otherwise, I really couldn’t find the place!!!”

these words.

Su Ming became interested again. He raised his eyebrows and looked at Skinny Gou and asked in depth.

"Since it's so difficult to find a trading location."

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

The thin dog nodded immediately and said without hesitation.

"The first transaction was two months ago. It was located under the stone bricks at the back door of Fulin's canteen. Two hundred grams of high-purity white powder was hidden."

"The second transaction was a month ago. It took place in the iron gate of Shengtian Textile Factory. At that time, I climbed in with a lot of effort and got [-] grams of high-purity white."

"As for the third time."

"It's in the doghouse at the end of Hexing Alley. There is a bag of candy in it, which is what you two police officers just mentioned."

"The only pity is..."

"Every time he makes a transaction, he hides the things first, and then calls me to pick them up. I have never had a chance to see the specific appearance."

"Of course, even if you give me a chance at that time, if you give me ten more courages, I will definitely not dare to take a look."

"After all, Brother Tie San's example is clearly right in front of you..."

The voice just fell.

Xu Changsheng tapped the table, squinted his eyes and spoke in a serious tone.

"Old Modu man."

"The drug dealers who can choose these three places to trade are definitely locals who grew up in Shanghai and are natives!!!"
