Autumn dusk is one of the most beautiful scenery in the world, if the "autumn dusk" is added to the label of "campus", it will be even more reverie, the golden leaves reflect the bright sunset, the red brick wall full of creepers is mottled, and the cool wind blows through the skirt of the girl holding the book, all of which converge into the quiet and beauty of autumn.

When Cheng Mo, Fu Yuanzhuo and Yan Yitong walked out of the teaching building, the campus had already passed the peak period of school, only three or three students carried schoolbags on the cement road while chatting and walking towards the school gate, several groups of people gathered on the playground to base the goal with schoolbags to kick the small field, the basketball court was more lively, the sound of banging echoed in the empty campus, and from time to time it was mixed with the shout of "passing".

Cheng Mo looked up at the orange-red sunset on the top of Yuelu Mountain, and the clear sky was dyed with a phoenix crown, a splendid scene, and said in his heart: It turns out that Star City also has such a beautiful time, why haven't you found it before? Maybe it's because of the big infrastructure construction a few years ago, even the sun is blurred like it is separated by several layers of gray gauze, which makes people not want to come out; maybe it's because his heart attack makes him ignore too many beautiful things.....

The three of them walked along the main road of the campus towards the direction of the gate, and the school security department was in the three-story building between the playground and the school gate, where not only the security department of Changya was located, but also the location of the general affairs office. Speaking of which, the playground is next to the school building, which should not be far away, but in fact, it takes a long slope to walk from the teaching building to the playground, and it takes about seven or eight minutes to reach the school gate.

Although Changya is very small compared to the Normal University or Yuelu Academy on the side, compared with other middle schools in Star City, Changya, which covers an area of 31 hectares, is really a behemoth, which is also because Changya is next to the foot of Yuelu Mountain, and the green area is large.

Cheng Mo counted the number of monitors along the road, and found that it was not as many as he imagined, and basically only set up cameras at key nodes, if you memorize the location of these monitors, it is easy to get around and reach the teaching building.

Cheng Mo's mind suddenly appeared in the school's floor plan, and calculated several routes to the teaching building through the gate without passing through key nodes, but if the other party is a student, he will definitely not choose to enter through the gate at night, it should be over the wall, assuming that the other party is a boarder, even the wall is saved, but it is a problem to get out of the student dormitory after eleven o'clock in the evening.

In addition, he also thought of the location of the teacher's dormitory that Shen Youyi told him that day, from where it was more convenient and concealed to go to the teaching building, without climbing over the wall or passing through any checkpoints.

When they walked to the end of the playground and could see the fountain at the school gate through an open green lawn, Cheng Mo turned around and walked to the other side of the school, passing through a plane forest that had begun to turn yellow, and they could see the small gray building with the golden "General Affairs Building" on the side wall, which was a little different from other atmospheric and modern buildings in Changya, the General Affairs Building was slightly shabby, and the gray pointed eaves were covered with tiles, which was very classical, but the building looked not classical, just like a brick house in the eighties and nineties.

Fu Yuanzhuo took Cheng Mo and Yan Yitong to walk through the corridor with eaves, and at a glance, most of the office doors on the first floor were closed, so the three of them went upstairs from the stairs in the middle of the small building, and the first room on the left side of the second floor was the office with the plastic sign of "Security Office (1)", but unfortunately the door was closed.

"Are you off work?" asked Yan Yitong with both hands clasping his schoolbag strap.

"There must still be people at work, at least there must be someone in the monitoring room. Fu Yuanzhuo said.

The three of them walked from left to right, Fu Yuanzhuo also knocked on the door, and still didn't see anyone, at this time, a middle-aged uncle wearing a white shirt, black trousers, black leather shoes, a LV belt tied around his waist, his hair stubble and stubble were a little whitish, and his face was wrinkled, standing at the top of the stairs, holding the escalator with one hand, and lying in the middle of the corridor, looking at the sneaky Cheng Mo The three asked in Xiangtan dialect: "How many of you, which one are you looking for?"

Fu Yuanzhuo, who was bending over against the glass and looking into an office, hurriedly stood up straight and said, "We're looking for someone from the security department." ”

The uncle said: "If you are lost and found, you will come tomorrow, now you are off work, I will give you a phone call if the bicycle is parked and locked, and go to him to unlock it with your student ID...."

When the uncle took out his mobile phone, Fu Yuanzhuo hurriedly said: "No, no, we have something to ask about the people from the security department." ”

"Something?" the uncle asked suspiciously, stopping and pulling out his phone.

Fu Yuanzhuo nodded, "We want to ask about the chalk drawings that insulted Teacher Shen in the first (9th) class last year.....

The middle-aged uncle looked Fu Yuanzhuo up and down, then at Cheng Mo and Yan Yitong, frowned and said, "Why are you asking this?"

"We are students in Teacher Shen's class..... This week, there was another chalk drawing in our class, which caused a lot of trouble to Mr. Shen and our class, and now we want to find out who is making such a nasty joke. Fu Yuanzhuo said.

"Have you still appeared in a different classroom now?" asked the middle-aged uncle with a frown.

"Well, that's what happened on Monday. Fu Yuanzhuo said.

"Then, why didn't Mr. Shen say it?" the middle-aged uncle asked again.

At this time, Cheng Mo suddenly replied aloud: "Because when I didn't arrive yet, I wiped it off....."

The middle-aged uncle glanced at Cheng Mo slightly, but his gaze did not stop, he continued to look at Fu Yuanzhuo and said, "We will deal with this matter in the security department, I don't need you to take care of it, hurry up and go home!"

After speaking, the middle-aged uncle half-turned around and walked downstairs.

Fu Yuanzhuo "huh" for a moment, chased to the top of the stairs and said loudly: "Uncle, I am still the president of the student union, this matter also has an extremely bad impact among our students, and our student union is also responsible for maintaining order on campus, which is also our business..."

The middle-aged uncle stopped and glanced back at Fu Yuanzhuo, "Student union?"

Fu Yuanzhuo finally felt that being an official seemed to have some effect, and hurriedly nodded like a chicken pecking rice..... replied: "Yes! We are all from the student union!"

The middle-aged uncle shook his head and said very funny: "The student union is not good, we adults can't catch this person now, what role can you children play?" ”

After speaking, the middle-aged uncle walked down a few more stairs.

At this time, Cheng Mo also arrived at the staircase, he looked at the back of the middle-aged uncle and said lightly: "Director Wu, it is precisely because you have no way to catch the perpetrator that we have to intervene.....

When the middle-aged uncle heard the words "Director Wu", he turned around and said in some surprise: "You know me?"

Cheng Mo shook his head, "I don't know, it's the first time I've seen you." ”

"Then how do you know that I am Director Wu?" The security department in Changya is not a particularly important department, because it has nothing to do with teaching and is not familiar to students, as the person in charge of the security office, Director Wu has no one in the school who knows him at all, let alone students, even the teachers don't know much about him, so Cheng Mo called him Director Wu, which made him a little surprised.

Cheng Mo said lightly: "Because I am good at reasoning, I can easily guess your position and name through observation....."
