The four people came to the security room of the bar. The narrow security room was filled with smoke and fire. Fifteen monitors were mounted on one wall, playing videos from various corners of the bar. There were also two computers and a computer on the desk.

When Da Yanwen walked in, he quickly asked the two security guards who were smoking and playing with their mobile phones to put out their cigarettes.

The two security guards originally had their legs resting on the table, looking out of shape. They were not too nervous when they saw the big-eyed text. They were about to laugh a little, but when they saw Gao Yuemei and Shen Youyi behind the big-eyed text, they immediately became serious and turned around.

He threw the cigarette into the bucket of instant noodles with oily soup floating in it, stood up and started to tidy up the security room consciously.

Da Yanwen shook his head helplessly, turned to look at Cheng Mo and said, "Are you watching the video of the bar position?"

Cheng Mo nodded and said, "Yeah! Set it to 11 o'clock..."

Da Yanwen patted the security guard who was sweeping the floor and said: "Big dog, what's there to clean up in your kennel? Just throw away the garbage...Hurry up and adjust the two videos at the bar to about 11 o'clock.

.....”

The security guard named Big Dog said "Oh" and quickly sat back on the somewhat deformed computer chair and started operating. Soon, the surveillance screen in front of the bar appeared on the computer monitor on the table. There were four sides of the bar in the field.

Surveillance video from each direction.

At 11 o'clock, Cheng Mo hadn't come yet. The middle-aged man and the student girl Xiao Wei were sitting in front of Kevin, talking and laughing.

Four people gathered around the surveillance dog.

Cheng Mo pointed to a surveillance camera on one side and said, "Enlarge this picture..."

Dagou took a screenshot according to Cheng Mo's request and enlarged the picture. However, because the light was a little dim, the quality of the picture was not very good. Cheng Mo frowned and pointed to the student girl's ears and said: "She is here

There are tiny headphones plugged in...but they can’t be seen on the screen.”

Gao Yuemei folded her arms and snorted coldly: "Are you telling a joke? You can see it with tiny headphones?"

Cheng Mo ignored Gao Yuemei's question and said to the big dog: "Brother Dog, please let go quickly..."

After playing about twenty minutes of scenes in three minutes, Gao Yuemei said impatiently: "You are wasting our time. If not, I have to call the police, otherwise something will happen to that girl and I will regret it."

lifelong....."

Cheng Mo said again to Big Dog: "Pause."

Dagou pressed pause as he was told, and Cheng Mo said calmly: "Look at her actions." At this time, the video happened to show a scene of a student girl pressing her right ear with her right hand.

Gao Yuemei sneered: "What does this mean? Does it mean that this girl is wearing tiny headphones?"

Cheng Mo turned a deaf ear to Gao Yuemei's sarcasm and said: "Go back to 11:19:22..."

Big Dog carefully dragged the progress bar back a little, and reached 11:19:22. The surveillance screen showed another image of the student girl pressing her right ear with her right hand.

Cheng Mo said: "Continue to go backwards to eleven fifteen minutes and forty-seven seconds."

The big dog continued to drag the progress bar. The picture was exactly the same as before. It was still the action of the student girl pressing her right ear with her right hand.

Cheng Mo said: "Go back to eleven o'clock eleven minutes and thirty-five seconds."

Everyone was shocked. The school girl's movements remained unchanged in the picture this time. Gao Yuemei's face changed and she said: "Play it."

Big Dog clicked play. This action was just a flash, not a continuous action, and the student girl's hand was not supported on the bar. In other words, it was just a subconscious action, as if there was something in her ears.

Things are average.

Da Yanwen said with an incredulous look on his face: "Xiao Nuo, how did you... see this?"

Cheng Mo said: "It's nothing strange. I have dynamic vision (Note 1). When I first started at the bar, I noticed her making this little move. And she didn't drink too much, but she went to the bathroom a lot.

a lot of....."

Gao Yuemei and Shen Youyi were also very shocked. Although this did not explain anything, it also proved Cheng Mo's strong and meticulous observation skills.

Gao Yuemei was stunned for a long time and said: "Is it possible that this action is a habitual action? Even...even...what does it mean that she is wearing miniature headphones?"

Cheng Mo turned to look at Gao Yuemei and said: "What else do I need to say? If this girl is not a police officer, she is premeditated to approach this man...and no matter which one it is, your behavior just now has no impact on

For her, it’s all very redundant..."

Gao Yuemei said unconvinced: "I am sitting next to her, so naturally there are not as many as you can see...Besides, this is just speculation, right? It's just a possibility, right? Can it be proved 100%?"

As long as there is a 10%... no! 1% possibility, we should not let this happen..."

Cheng Mo said coldly: "Please look at the picture carefully... She started drinking Long Island Ice Tea. After drinking it, she acted as if nothing had happened and her face did not change... What do you think of four cups of White Beauty?

Can it be better than a cup of Long Island Iced Tea?”

"Look at the way she holds the cup and the way she uses the stir stick...Only a person who drinks cocktails regularly knows that holding the cup must not affect the temperature of the cup, and only then will she know how to stir the ice cubes with the stir stick.

It’s time to pull up from the bottom up…”

"Do you think such a person doesn't know which cocktail has a higher alcohol concentration? Would he say nothing when I mixed the White Lady?"

Gao Yuemei was left speechless by Cheng Mo's question. She looked at the video and recalled that when she just watched the girl being supported by the middle-aged man, she did not look like she was drunk. At this time, she was completely convinced.

He understood Cheng Mo's inference, but still managed to sarcastically say: "You observe other girls very carefully! Are you afraid that you have bad intentions?"

Shen Youyi pulled Gao Yuemei and persuaded her softly: "Forget it, Xiaomei, I think you have really misunderstood this handsome guy, let's go!" Then Shen Youyi said slightly to Cheng Mo and Da Yanwen: "

Sorry, my friend didn’t mean it, she just likes to fight injustices, especially when she hates seeing men cheating on women..."

Cheng Mo said noncommittally: "In that case, I will go back to work. You have delayed my time to make money for a long time." After finishing speaking, Cheng Mo walked towards the door of the security room.

Gao Yuemei stretched out her hands in front of Cheng Mo to stop her, bit her lip and said: "This matter is over, there is still another matter that is not over... Just now, why did you say that I paid to go on a date with you!

What else did you say about not spending the night with me...you shameless..." At this time, he felt that calling Cheng Mo a shameless person was a bit too much. Gao Yuemei paused, thought for a few seconds, and then changed his mind.

Said: "How can you say such shameless words!"

Cheng Mo looked at Gao Yuemei who was standing in front of him. She was slightly shorter than Zhi Zhi, about 17cm tall, but the height difference between her and him was not very obvious when she was wearing high heels. She was almost leaning in front of him and looking at him. Her

There is a burning bonfire in the eyes, which is an unyielding will, rather than the unwilling anger of discovering that one is actually wrong.

This immediately made Cheng Mo feel a little confused. He really didn't expect that Gao Yuemei, who was very queenly in school, was so difficult to deal with in private, and could even be said to be a bit difficult...

So Cheng Mo stepped back a little, keeping a distance from Gao Yuemei and said: "Let's put it this way! I speculate that the middle-aged man in the plaid suit is the manager of an investment bank... You will find out if you pay attention to his mobile phone.

It shows the United States, London and Chinese time... His forehead sweats easily. Sweating in such weather can only mean that he lacks vitamin D in his body, which means he needs to stay in a closed room for a long time.

In this space, the sun may not see the light for a long time... He is very sensitive to numbers and can accurately calculate how much he should pay for a few drinks without thinking... He is very generous in paying the bill.

It means that the income is very good...all this means that he works in an investment bank!"

"When working in an investment bank, there is an unspoken rule, that is, people with low-level positions can only wear plain suits, usually black and blue, and only people with high-level positions can wear fancy suits...

.I can tell you clearly that that girl is not simple...I stopped you at that time, just because of the tip you gave me, so I stopped you to prevent you from getting into trouble..."

Gao Yuemei was completely stunned by Cheng Mo's Sherlock Holmes-like observation ability. She was stunned for a long time and said: "Then, I should still thank you?"

Cheng Mo said expressionlessly: "No, since you just sat in front of me, paid the fee, and became my guest, I have the responsibility to relieve you of the difficulties you are about to face..."
