Chen Guo sat on the small sofa in his bedroom, and took the photo in front of him. The person in the photo looked to the side with his eyes on his face a little indifferent.

After Chen Guo took a photo of Master Liu, he developed a total of two, one was handed over to Jing Zhiguo, and the other was kept by himself. Jing Zhiguo was worried that Chen Guo would keep his hands behind, and when Chen Guo handed over the developed photo to him, he made it very clear that he would destroy the negative and not leave any traces related to this photo. But Chen Guo didn't do what Jing Zhiguo said, he just destroyed the negative, but left a photo of Old Master Liu in his own hands.

The Provincial Police Department had another case, and Jing Zhiguo did not go home for dinner. Chen Guo ate by himself, went upstairs and returned to his bedroom, closed the door, turned on the light, took out a small notebook from the drawer on the small desk leaning against the door, opened it, and took out the photo of Master Liu. Looking at the old Master Liu in the photo, at this time, Chen Guo realized that this old Master Liu is very likely to be really not an ordinary person! Just now--

The school bell rings! The school uses a brass bell to and from class, which is shaken by Master Liu at the end of the day. The bell sounded so crisp that it could be heard all upstairs and downstairs in the school. Ring this bell that still has to say, the bell for class and the bell for school are not the same, the bell for class is shorter, and the bell for school is longer. Therefore, as long as you listen to the bell that Master Liu shakes, you will know whether it is to go to and from class or school. Hearing the bell ringing for the end of school, Chen Guo dismissed the students, returned to the teacher's office by himself, packed up his things, and prepared to go home. But at this moment, I suddenly found that a fountain pen that I always carried with me was missing. I found the desk, the bag, and the body, and I didn't see it, and I thought that it might have been left in the classroom, so I went back to the classroom where I had just taught the students. For a long time, Chen Guo has a habit, that is, when teaching students, occasionally when he has an insight, he will use steel notes to write in a small notebook, which is a habit and an accumulation. Otherwise, after class, maybe you'll forget it and never remember it again. She searched and searched, but there was nowhere to go, and when she accidentally looked at the small wooden slot under the blackboard where the chalk was placed, she saw that the pen was in the small wooden trough. I think it may be that while lecturing, I wrote in my own little notebook, and I left the pen there. Chen Guo picked up the pen and returned to the teacher's office, but when she walked to the door of the office, she saw Master Liu walking out of her desk near the door. Chen Guo was stunned for a moment, and immediately put down a smiling face, and greeted, Old Master Liu! Old Master Liu was very calm, and when he saw Chen Cha, he greeted, hey! Don't you have to go upstairs and downstairs every day after school? You teachers are all busy people, sometimes, after class, you leave, let's take a look upstairs and downstairs, and if you don't lock the door, we will help lock it. To be honest, in our school, it's okay to lock the door or not! That's it! Be! Master Liu, then you go downstairs! Be! Then you are busy, at home and outside the house, don't be too late, almost go back, ah! Well! When he arrived at his desk, Chen Guo casually glanced at his desk, but found that something was wrong. There are four drawers on the left side of the desk from top to bottom, the top one is unlocked, and the bottom three are locked. The top one is not tightly closed. That drawer doesn't contain anything important, so what if it doesn't close tightly? A teacher prepares for classes all day long, and what important things can he have, that is, those notes for preparing for class. Chen Guo felt that he had opened this drawer when he was looking for a fountain pen just now, but when he saw that there was no one, he closed it all at once. Chen Guo's heart trembled for a moment, and he opened the drawer, and there was no trace of movement inside. Chen Guo thought that it might be that he didn't close it tightly since he opened it just now, and his mind was all on the fountain pen. When I left the school gate, the sky was already a little hazy, and the lights in the guard room at the school gate had been turned on, and the yellow light emitted by the incandescent lamp looked very warm. The gate was locked, but the small door next to the gate, which could only be walked, was open. Old Master Liu still saw Chen Guo coming out of the teaching building in the room where the lights were lit, and waved his hand to Chen Guo outside through the window with frost on the edge of the glass, even if it was a greeting.

Chen Guo was walking on the road, thinking of what had just happened, and suddenly felt a little strange. She pondered what had just happened for a while in her mind, and felt that her desk drawer must have been touched. Supposedly, an old man who beats the school is on the change, what can he do? But you can't say that, what time is this? When it's messy! Suddenly, Chen Guo's head suddenly surged with a lot of things related to this old Master Liu.

To be honest, this old Master Liu is very good to Chen Guo, not to mention very good to Chen Guo, and very good to Chen Guo and the teachers and students in her school. It feels like it's always so hot! The face is always so smiling! If you don't say that the old master Liu is not a good person, I'm afraid no one will believe it! But it was such a person, and now Chen Guo had doubts in his heart, and suddenly a guess came to Chen Guo's heart! The time we went to Dongdian with Principal Wen, maybe it was this old Master Liu who poked him out! Chen Guo recalled that that morning, she went to the school to find Wen Changjun, and the two of them discussed going to Dongdian. Of course, she and Wen Changjun borrowed the light of the post and telecommunications bureau and took someone else's car, but the people from the post and telecommunications bureau didn't know in advance that they were going to Dongdian, and it was the people from the post and telecommunications bureau that Wen Changjun was looking for temporarily.

If you have a doubt in your heart, then it has to matter if you think about it! Chen Guo thought that when Wen Changjun was the principal, this old Master Liu was very good to Wen Changjun. What is the school? School is a place where cultural people are piled up! Those cultural people, those teachers, not to mention all of them, are almost the same. You look at the aisle steadily, carrying a bag, or holding a clip with the diaphragm socket, looking at someone who is always smiling, quite docile, in fact, it is hard in the bones! There are very few people who can be looked down upon! Then let's be literate, how many of you are literate? We know arithmetic, and we know geometry, how many of you know? How many know? This is true. It is true that there are few Manchukuo people who are literate and can do arithmetic, so if you want to talk about geometry, you really know even less! That old Master Liu's behavior in front of the principal made people look uncomfortable. That old Master Liu is a little kind of welcome to Wen Changjun, and not only is he like that to the new Japanese principal, but he is also very good! But you say, this is also a strange thing, the new principal seems to be a Japanese stubborn donkey, whether he is also high in his bones is not easy to say, in general, it is also very gentle to people, but there are not many people who can look at anything! Then you say, a watchman, seeing the principal of the school, that is, the main leader of the school, behaves respectfully, that should be reasonable! In case the principal is unhappy and resigns us and lets us go home, we lose our jobs, isn't it miserable! It's normal to feel a little frightened. But at this time, Chen Guo seems to be not like that! What made Chen Guo even more strange was that the original principal Wen Changjun treated Lao Master Liu, although Wen Changjun was the head of a school and Lao Liu was a dozen, but Wen Chang was polite to Lao Liu on the surface, but behind his back, he seemed to be a little afraid of this Lao Liu Master. Chen Guo encountered this situation once. Chen Guo thought at the time, Principal Wen is really a good person, you look at others, even if you look at a school worker, you also give respect.
