Yang Yuanyuan flickered the guard into a daze, laughed in her heart, walked through the small door at the school gate, and walked into the school.

Yang Yuanyuan was not afraid that the guards would find out that she was lying, and even if she did, she would throw a mouse trap and dare not call the school leader.

The facts are the same as Yang Yuanyuan thought, after the guard put Yang Yuanyuan in, he sat in the guardroom, and he was not in the mood to drink tea and read the newspaper, and he was very worried.

But after a few minutes, the guard's heart slowly became calmer, no longer so nervous and overwhelmed, after regaining his composure, he began to think about it in his head, and suddenly found the loophole in Yang Yuanyuan's words.

"Confidential police operations? But..."The guard remembered that Yang Yuanyuan didn't seem to have anything on her ears, she didn't look like she was wearing a liaison, and how she could communicate with others without a liaison.

"Is it a liar? That's not right, looking at the police badge doesn't look like it's fake, it should be a real policeman. The guard picked up the phone and thought about it.

"Hey~ Forget it, no matter what she is, even if it's a liar, the students are still in class in the daytime, and she doesn't dare to do anything." After careful consideration, the guard put down the phone in his hand and did not call the leader to inform the leader that the police had come to the school.

He thinks a lot, if Yang Yuanyuan is a fake policeman, she will have nothing to do when she enters the school in the daytime, what bad things can she do when she looks like a little girl, even if she does bad things, she will be stopped by so many people in the school now.

But if Yang Yuanyuan is really a policeman, the police really have any secret actions, because he called the comrade leader, and the deployment of a month was all in vain, and the police uniform told the school leader that he was the reason for this, then he must have no good fruit to eat, and the school will not remember his impartiality and duty, and will only use the topic to deduct wages and bonuses.

So after the guard thought about it carefully, he turned a blind eye and didn't care about Yang Yuanyuan, just as if he hadn't seen her as a person, and continued to drink tea and read the newspaper.

Yang Yuanyuan's side, although she walked into the campus without alerting anyone by shaking the guards, she and the guards consumed a lot of time.

After spending at least five minutes with the guards, Yang Yuanyuan walked into the campus and could no longer see Wang Hongwei.

"He seems to have entered that building." Yang Yuanyuan stood in the school playground, recalling carefully, remembering that she saw Wang Hongwei walk into the teaching building on the right just now, and hurriedly ran towards the teaching building.

But when she entered the teaching building, Yang Yuanyuan went back and forth in the long corridor, empty and empty, only the sound of the teacher lecturing and the sound of students writing with pens, Wang Hongwei was gone.

"Damn! That's where he can run. Yang Yuanyuan looked back and forth at the empty corridor, gritted her teeth and ran towards the stairs, hoping to find Wang Hongwei on other floors.

On Wang Hongwei's side, he was gloriously lost, the school was very large and there were many classes, although he had the name of the class of the fourth female high school student of the victim in his hand.

But every class in each school year, science and liberal arts, etc., made him completely confused, looking at the class cards hanging on the corridor and completely crying, I don't know how the classes in the school are arranged.

The front of this floor is the first year of high school, the back is the third year of high school, and the upstairs is full of high school sophomores, as well as laboratories and so on.

In the end, when Wang Hongwei got lost in school, he saw a male teacher head-on, and after asking the male teacher for directions, he learned where the fourth victim's homeroom teacher was.

And the male teacher seemed to be the same as the guards, treating Wang Hongwei as a student of the school, Wang Hongwei didn't show his identity, so he directly got the news he wanted, but the price was that he was lectured by the male teacher, mainly about clothing.

"Huh~~ It's not easy to finally find it." Wang Hongwei followed the path told him by the male teacher, and it took more than ten minutes to come to the door of the teacher's office, and he couldn't help but take a long breath, this school is like a maze.

"Knock knock! Knock knock!! He raised his hand and knocked on the office door twice.

"Please come in." A woman's voice came from inside.

When Wang Hongwei heard this, he held the handle on the door and twisted it slightly, pushed the door in, and saw that there were rows of desks in the teacher's office, most of the seats were empty, and there were three or four teachers sitting at the desks, as if they were preparing lesson plans for the next class, or correcting homework.

When these teachers heard the sound of the door opening, they raised their heads and looked at Wang Hongwei who opened the door, seeing that Wang Hongwei should be a student, but looking at the students, it should not be their students, so the teachers lowered their heads and continued to do their own things.

"Hello, excuse me, may I ask if the teacher is the homeroom teacher of the sixth class of the second year of high school?" Wang Hongwei looked back and forth, and didn't know that it was the person he wanted, so he walked over to the nearest teacher and asked in a low voice.

"Huh!?" Wang Hongwei asked a middle-aged female teacher in her forties, after she heard Wang Hongwei's words, she raised her head and looked at Wang Hongwei strangely and said: "I am the head teacher of the sixth class of the second year of high school, this student, do you have anything to do with me?" ”

Wang Hongwei was overjoyed when he heard this, he didn't expect to find it so coincidentally, so he immediately put his hand into his arms, took out the national security card from his inner pocket, and showed it to the middle-aged female teacher

The middle-aged female teacher was shocked when she saw the national security card, she didn't expect Wang Hongwei to be a member of the National Security Bureau, she was very surprised that the people from the National Security Bureau came to her for something, and she was even more surprised that the person with the national security card was so young.

"Hello, I'm from the National Security Bureau, may I ask if Wang Yu is a student in your class?" Wang Hongwei took the national security card back into his arms, and then whispered.

"Yes." The middle-aged female teacher nodded, looking at Wang Hongwei with suspicion, not believing that he was from the National Security Bureau, after all, Wang Hongwei's age and temperament were too much like a student.

"Well, can you come out with me, I want to talk to you about Wang Yu alone." Wang Hongwei said, looking at the teacher's office, several other teachers who were busy with their own affairs.

"Okay!" Although the middle-aged female teacher doubted Wang Hongwei and whether his National Security Bureau was real, she still nodded, agreed with Wang Hongwei's words, took off the glasses on the bridge of her nose and put them on the table, and stood up from her seat.

Wang Hongwei and the middle-aged female teacher walked out of the teacher's office and went to the corridor outside, where no one was there, only the sound of the teacher lecturing in the nearby class.

Wang Hongwei looked at the suspicious expression on the middle-aged female teacher's face, and knew what she was suspicious, not only smiled, but the whole person's temperament became calm and stable, which felt incompatible with his appearance.

The middle-aged female teacher couldn't help but flicker with surprise in her eyes when she saw Wang Hongwei's temperament change suddenly.

"I'm sorry to disturb your work, I want to ask a few questions about Wang Yu, I hope you can answer truthfully." Wang Hongwei said to the middle-aged female teacher very formulaicly.

"Okay." Although the middle-aged female teacher's tone was very calm, she could still see surprise on her face, the contrast between Wang Hongwei and the back was too great, and now it looks like Wang Hongwei is really from the National Security Bureau, especially what he just said.

"Do you know the news that classmate Wang Yu has died?" Wang Hongwei said, took out the notebook from his arms, and pulled out the pen cap.

"yes, I know." The middle-aged female teacher nodded, with some sadness in her eyes: "Wang Yu, she is a good child, I like that child very much, she studies very hard, and she will definitely be admitted to a prestigious university in the future, but I didn't expect it... Ay! ”

"Please mourn and be good." Wang Hongwei looked at the middle-aged teacher and sighed, and after comforting him, he continued to ask: "Before Wang Yu's death, was there anything strange?" Or Wang Yu, did she have any strange behavior! Something like that? ”

"Huh?" The middle-aged female teacher, who was immersed in sadness, gave Wang Hongwei a strange look when she heard this, but she still recalled it seriously.

After half a ring, the middle-aged female teacher shook her head and said, "No, it's normal, there's nothing strange about it, I will go to class on time every day..."

Halfway through speaking, suddenly the middle-aged female teacher seemed to think of something, and hurriedly said, "That's right! I remembered strange things! ”
