(Thanks to the two 10,000 rewards of "no tooth decay", thanks to the 15,000 starting coins of "Book Friends 171106084012012", and the first one owed before, and the three more are owed)

The middle-aged man turned his head and stared at Cheng Mo's eyes tightly, his eyes were very sharp, and his right eye was slightly wider than his left eye, this quiet atmosphere made the air seem to freeze, after a while, the middle-aged man saw that Cheng Mo did not avoid his eyes at all, it didn't seem like he was lying, he really didn't know him before, and said with some surprise: "You even know my name, not just my surname?"

Cheng Mo nodded, "If my guess is correct, you should be called Wu Yan (ke)." ”

Hearing Cheng Mo say each other's names firmly, Fu Yuanzhuo and Yan Yitong looked at Cheng Mo with incredulous expressions, and the two of them couldn't imagine how Cheng Mo knew each other's names.

The middle-aged man was also very surprised, first froze for a moment, and then seemed to remember something, looked at Cheng Mo and smiled slightly, shook his head and said: "I was almost frightened by you, you looked at the information bar at the entrance of the corridor! There is my photo, name and job title on it......

Fu Yuanzhuo and Yan Yitong suddenly realized, and also thought that Cheng Mo must have obtained the other party's information through the content of the bulletin board, otherwise it would be really unreasonable! No matter how powerful Cheng Mo is, it is impossible to guess the other party's name without knowing the other party.

If you really can guess it, then Cheng Mo is really not a human, but a god!

After a pause, the middle-aged man said seriously: "You three little guys, don't waste time here, investigating Teacher Shen's case is a matter for our security department, and I also promised you Teacher Shen that I will help her catch the criminal, you should go home as soon as you get out of school, don't let your parents worry." ”

After speaking, the middle-aged man who was called Wu Yan by Cheng Mo walked around the corner, held on to the handrail of the stairs and continued to walk downstairs, there was a sound of knocking footsteps in the corridor, and the middle-aged man's somewhat gray round head gradually disappeared from the field of vision of Cheng Mo and the three of them.

Cheng Mo sneered, and then said nonchalantly: "No wonder you can't catch the perpetrator, it's strange that you can catch it at this level!"

After Cheng Mo's sarcasm sounded, the footsteps in the corridor stopped for a moment, and then Wu Li walked back to the corner of the stairs, looked up at Cheng Mo and the three of them, frowned and scolded: "What do you three want to understand? You Teacher Shen is the one who taught you in this way? If you don't want to leave, I will inform you now that Teacher Shen will take you away..... The cadres of the student union are also selected, and now the student union chooses some cadres....."

Fu Yuanzhuo didn't expect Cheng Mo to say such unpleasant words, so he secretly pulled Cheng Mo, "I'm sorry, Director Wu, my classmate spoke a little rushed, let's go!"

Seeing that Wu Yan didn't pay attention to them, he turned around and walked downstairs, Fu Yuanzhuo tilted his head and whispered to Cheng Mo: "Forget it, Cheng Mo, let's go first, think of another way!"

Cheng Mo said lightly: "Then let's go." ”

Yan Yitong asked cautiously: "Cheng Mo, did you know Director Wu's name after reading the bulletin board?"

Cheng Mo shook his head, "I can't say that completely, there are names and positions in the bulletin board, but ...... There are no photos, all of them have been torn off..... And the names of thirty-seven people are posted in the information disclosure column, and there are three of them surnamed Wu, one is called Wu Ping, one is called Wu Tianyang, and the other is Wu Peng (KE), which is a stone character for stone and a delicious word for Ke..... To be precise, Director Wu should be called Wu 砢 (luo), but I think most people will call him Wu 砢 (ke), and he himself should have acquiesced to everyone calling him Wu Li, after all, few people know that the word '砢' is also pronounced as luo. ”

Fu Yuanzhuo looked back at Cheng Mo with a shocked expression, "There are no photos..... How do you know he's Director Wu?"

At this time, the three of them had already walked to the corner of the stairs one after the other, Cheng Mo glanced at the corridor on the first floor, and listened carefully to the voice, "I'.....ll talk about it when I go downstairs."

Yan Yitong and Fu Yuanzhuo looked confused and puzzled, they really couldn't figure out how Cheng Mo accurately judged that the other party was Director Wu through such a clue, and what is the difference between Cheng Mo's emphasis on reading ke and luo? .

Cheng Mo knew what Fu Yuanzhuo and Yan Yitong were thinking, and said in a flat tone: "You have to pay attention to the details, and reason through the details, just like doing questions, the more conditions, the easier it is to derive the answers..... You don't use wisdom to observe, that's why you are confused....."

Yan Yitong's eyes lit up, and he said happily: "Just like you can infer from my dress that my favorite type of music is vaporwave, right?"

Cheng Mo nodded.

Fu Yuanzhuo recalled with a tangled face, thought for a long time and said, "But.... I really didn't find anything special about Director Wu?"

Cheng Mo shook his head, "Let you find the details, it's not that you only pay attention to how he is different from others, it's also important to see the commonalities, and you'll know later, how I judged that he was Director Wu." ”

At this time, the three of them had already walked to the corridor on the first floor, and when they turned around, they could see Wu Li standing at the end of the corridor, looking at the information column with only his name and position, and not a single photo.

Wu Peng only remembered the National Day at this time, because there were leaders to inspect, all departments of the school had to make National Day propaganda posters, to create a National Day atmosphere, their general affairs office because there was no bulletin board, can only use the information column as a bulletin board, in order not to stick to the photos, first take down all the photos in the information column, and then paste the poster, now the National Day holiday is over for almost a week, naturally to remove the poster.....

So the student with glasses just now didn't know his name and position through the information bulletin board at all.

Wu Yan stood in front of the information bar and turned around, quietly facing the three Cheng Mo who came one after the other, and when the three approached, he looked at Cheng Mo and said, "Tell me, how do you know that I am Wu Yan (ke)?"

Cheng Mo glanced at Wu Pei, who was about as tall as him, and said expressionlessly: "I not only know that your name is Wu Pei (ke), but I also know that you have been a soldier and participated in the war against Vietnam, you are a glorious soldier remnant of war, and you are also the brother of the principal Wu Lei....."

Wu Yan looked at Cheng Mo and sneered: "Then you still say that you don't know me?"

Cheng Mo also sneered, "You need to know you to deduce this information?" Your right hand is at the junction of the small fish and wrist, the heel of the finger, and the first joint of the finger has a callus, and the index finger is naturally a little away from the thumb, high and low shoulders, this is because of the long-term shooting, and your standing posture is very straight, at first glance, it is a standard military posture, and your voice is loud, just like shouting slogans, your right eye is more divine than your left eye, and you are almost writing the words 'I have been a soldier' on your face!"

Wu Li looked down at his right hand, and sure enough, as the little ghost in front of him said, his expression changed from contempt to surprise, "That.... Then how do you know that my brother is Principal Wu? Not only did I participate in the war against Vietnam, but I was also a soldier who was a remnant of the war?"

"Principal Wu's full name is Wu Lei, he is from Xiangtan, your Xiangtan accent, plus the name Wu Li (ke) in the information column, to be precise, Director Wu should be called Wu Lan (Luo), the word 'Lei Peng (Luo) extraordinary' is a metaphor for people with peculiar talents....." After a pause, Cheng Mo looked Wu Li up and down, and said lightly: "Your whole body is a bargain, the belt is a luxury, and the belt should be given to you by Principal Wu, right?"

Wu Yan didn't expect the young man in front of him to be able to tell the origin of his name, and even guessed that the belt was given by his brother, he opened his mouth slightly, his face was full of disbelief, and he looked at Cheng Mo and said, "That.... That... How did you know that I had participated in the war against Vietnam?

"The vast majority of healthy people will not always hold on to the staircase railing, only because of the long-term inconvenience of their legs and feet, people who are used to it will always hold on to the railing down the stairs, as a soldier can retire to our school as the director of the security department, not that you are the younger brother of Principal Wu, that is to say, you have a good reason, then the war disabled soldier is one of the most favorable reasons..... And your age is about 50 years old, and because of the frequency with which you use guns and the battle wounds you have received, you can only participate in the 84-90 years of the war against Vietnam..... I guess you participated in the battle fought by the 47th Army in 86-87...."

Cheng Mo was able to guess so accurately because he had talked with Principal Wu and had been to Principal Wu's office, and through the conversation with Principal Wu, as well as the furnishings and layout of the office, he probably knew what kind of person Principal Wu was, and just now he had a more accurate grasp of what kind of person Wu Li was.

Wu Yan naturally didn't know that Cheng Mo was even him, his expression had changed several times, from disbelief to surprise to shock to speechless, he didn't expect the observation of the student in front of him to be so terrifying, looking at Cheng Mo and not knowing what to say.

Yan Yitong and Fu Yuanzhuo felt that they were simply watching the plot of the movie, someone met a god-level fortune teller with an iron mouth on the road, Cheng Mo, who was holding a half-immortal flag, took out a turtle shell and copper coin, and calculated a hexagram for Director Wu, and knew the other party's past and present lives....

The two silently shouted in their hearts: Cheng Mo, the bunker! Cheng Mo, the bunker!

The four of them stood in the corridor of the sunset and evening, no one spoke, Cheng Mo was waiting, and Fu Yuanzhuo and Yan Yitong were reminiscing about Cheng Mo's wonderful performance just now, as for Wu Yan, he was thinking about whether he should believe that the student in front of him could find the mysterious perpetrator who couldn't even be photographed by the surveillance and came and went without a trace like a ghost.

After a moment of silence, Wu Yan spoke, "What's your name?"

"Cheng Mo. ”

Wu Li took out his mobile phone from his trouser pocket, "I'll tell you Teacher Shen about this, as long as she agrees, I can show you the information collected by the security department.....
