The head teacher of Senior 3 (5) is named Chen, the head of the mathematics group, female, 35 years old, married.

She knew Ji Feng and knew that he was Ji Yunyun's relative, and she had a deep impression of him. After all, not every parent meeting would have someone late or leave early, and there was even one time when someone came with blood on his body.

"Are you here to look for Yunyun?" she asked kindly.

Unexpectedly, Ji Feng said, "Excuse me, Teacher Chen, I want to ask you about Miao Tong."

Teacher Chen was immediately surprised: "Miao Tong is not..."

"I want to check again." He was vague, "Tell me about this child."

Teacher Chen is knowledgeable and has a wide range of knowledge. After a moment of silence, he said, "She is a good child, studying hard, and her grades are relatively stable. But since the winter vacation this year, her grades have dropped a bit. We are worried that the pressure from her parents is too great. We have talked to her parents, and they said that the child is pushing herself, and they are also very anxious."

"What is her personality like?"

"She is a very quiet girl, helpful and popular in the class." Teacher Chen said, "She got into trouble, and her classmates were very sad."

Ji Feng nodded and asked, "As far as you know, did Miao Tong show any signs of being in love?"

Teacher Chen hesitated and said, "It is possible. Generally, when a student's grades suddenly drop, it is either because of problems at home or because of their own problems."

"With whom?"

"I'm not sure. Nowadays, children all have mobile phones, so it's hard to tell at ordinary times." Teacher Chen answered.

Ji Feng: "Has she had conflicts with anyone?"

Teacher Chen answered cautiously, "Almost none."

She didn't lie, but she might have concealed something. Was she trying to protect the students? Ji Feng remained calm and asked, "I want to talk to a few students. Is that convenient?"

Teacher Chen said awkwardly, "Everyone thinks this matter is over. The college entrance examination is less than a month away..."

"That's right." Ji Feng didn't force her and changed the subject. "Then I want to ask you something personal. How are Yunyun's grades? Is she dating someone at school?"

"If Yunyun performs normally, she will have no problem getting into a university, but if she wants to focus on the exam, she still needs to work harder." Teacher Chen caught up with Ji Yunyun's parents and talked about everything in detail. "I know your family situation is special, but the college entrance examination is very important to your child's life. No matter how busy you are, you have to pay attention in the last month and take good care of your sister and take good care of her life..."

Ji Feng was so frustrated by the lecture that he had to respond repeatedly: "Yes, yes, I will pay attention."

Chen Teacher: "You should not put too much pressure on your child. Yunyun is not lazy. It is most important for her to keep a calm mind and perform normally."

Ji Feng: "You are right."

After a long speech, Teacher Chen's cautiousness towards the police has turned into authoritative guidance to parents. He said with a slightly relaxed tone: "It's a pity for Miao Tong. Her grades were so good before. Although they declined a bit this year, she should have no problem getting into a key university. I originally thought that it would be good to be recommended by the school..."

He took the opportunity to ask: "How is the school's recommendation for admission?"

"The final exam results of the first and second year of high school, the results of the college entrance examination, and the scores of the first and second mock exams of the third year of high school, and of course, the teacher's recommendation." Teacher Chen said, "Pick three to four out of a dozen places. However, our school does not have students admitted to Tsinghua University or Peking University. The best place is the quota for Peace University."

Ji Feng smiled and asked, "How many students are on the list in your class?"

Teacher Chen was quite proud: "There are three in our class."

He showed a shocked expression: "I thought classes 1-4 were the good classes."

"..." Teacher Chen understood the difficulty of his work, but he was also very speechless about such parents, "Classes 1 to 4 are liberal arts classes, and our class 5 is a good class among science classes."

"So," Ji Feng, the incompetent parent, sighed, "our Yunyun's grades are pretty good?"

Teacher Chen: "She ranked 78th in the second mock exam."

Ji Feng: "..."

Is this good or bad?

"Who are the three students?" He asked casually.

Every parent is curious about the good students in the class. Teacher Chen hesitated for a moment and replied: "Wu Jingcheng, Miao Tong and Tong Moli - but Miao Tong and Tong Moli's hopes were not great. Wu Jingcheng won the competition award, so it was basically decided that he would win." Ji Feng nodded

, asked a few more questions about Ji Yunyun's daily life, dispelled Teacher Chen's concerns, and ended the conversation.

At this time, the lecture in the auditorium was over, and a large number of students came out of the auditorium, like a group of wild ducks letting off some steam, with a lot of noise.

He went to the chemistry office of the first year of high school and asked the chemistry teacher who was in the laboratory building at the time.

She was a girl who had just graduated and had just signed a contract with the school. The day of the incident was the first time she led the students to do an experiment.

In order to ensure the smoothness of the experiment, she arrived at the laboratory one class early, checked the instruments, and did it herself first.

Regarding what happened that day, she said: "I didn't notice anything. I was concentrating on my own work. Although it was just a small experiment, chemistry experiments are more dangerous. Students will have this or that problem. I was rehearsing in advance, and I didn't hear it until someone shouted "someone's dead" downstairs."

Ji Feng asked: "You haven't seen the dead?"

The chemistry teacher shook her head.

Ji Feng: "What time did you go to the laboratory building?"

She estimated the time: "Our first class in the afternoon started at 1:30, and the bell hadn't rung when I went there. It was around two o'clock."

Miao Tong jumped from the building at 14:45, which happened to be the second class in the afternoon.

"At that time, was there anyone in the laboratory building?"

"I only know that there should be no one on the first and second floors, and I didn't hear any sound." The chemistry teacher apologized, "The chemistry laboratory is on the second floor. I didn't go upstairs, so I don't know if there was anyone there."

Ji Feng thanked her and went to find the cleaner.

He said that he started cleaning the laboratory building at around 1 pm according to the daily work process. He cleaned from the toilet and corridor on the fourth floor to the first floor.

Therefore, he could tell the police with certainty that there were only six people in the whole building when the second class started.

The chemistry teacher arrived first, and then as soon as the second class started, four high school sophomores came to do experiments. He was cleaning the second floor and was about to go to the first floor.

Next, he swept the corridor on the first floor. While cleaning the toilet, he heard footsteps and someone went upstairs.

But he was mopping the floor in the toilet at the time and didn't come out to see who it was.

"Are you sure it was just one person?"

"It definitely was." The cleaner was quite old and still had a loud voice. "My ears are very good. I don't forget anything. If it's one person, it's one person. There's no second person!"

His testimony was consistent with his previous confession.

The badminton students and the students who were memorizing vocabulary were the only ones left.

It was almost lunchtime. Ji Feng returned to Class 3 (5) and stopped his sister who was going to the cafeteria to eat: "I'll take you out for lunch at noon. Where's your friend? Let's go together."

He took the two girls out of the school gate openly and went to a small restaurant nearby.

"I have something to ask you two." Ji Feng spread out the floor plan he had drawn and asked, "You were in this badminton court at the time. What was the exact location?"

Ji Yunyun pointed to a place.

"Where did Miao Tong go?"

She drew a line.

..Badminton court.....Basketball court....

.. ..X...................

.. . . . . . Laboratory building.............

(Note: X is where Ji Yunyun is, .. is Miao Tong's route)

"The badminton court and the laboratory building are a bit far apart, and there is a green belt. How can you be sure that person is Miao Tong?" Ji Feng was not polite to his sister at all and asked quite sharply.

This official attitude, on the contrary, aroused Ji Yunyun's competitiveness. She said very seriously: "Miao Tong and I are very familiar with each other. Although I didn't see her face clearly, the hairstyle, clothes and the way she walks are all hers. I would not make a mistake."

"Isn't she wearing a school uniform?" Ji Feng questioned, "Her hair is also in a ponytail. Almost all girls look like this."

Ji Yunyun & Xiaoxiao: "..."

"Miao Tong has studied ballet. The way she walks is particularly beautiful. Most people can't imitate it." Xiaoxiao said, "We all say she looks like a swan."

"And the hair is different too. Although the school requires not to dye or perm hair, Miao Tong's hair is naturally curly. She and another girl in our class are the only ones with this kind of special curly hair. That person's hair is not as long as Miao Tong's." Ji Yunyun added.

Ji Feng asked, "You mean, you definitely didn't see it wrong?"

"Yes! And I called her, and she turned around and waved to us." Ji Yunyun looked at him provocatively, ready to take on the challenge.

Ji Feng was not used to her, and passed it over expressionlessly: "What was her condition on the day of the incident? Was there anything different from usual?"

The police had asked this question before, but Ji Yunyun still answered seriously: "She was a little different, but I don't think she looked like she was going to commit suicide."

"Talk about the details, not the feelings." Ji Feng reminded, "What did she say and what did she do?"

The two girls pondered.

After a long while, Xiaoxiao finally said, "I think... uh, I don't know how to say it..."

"Don't worry, just say it." You can control your sister

as you like, but you can't control other people's children. Ji Feng encouraged her, "How do you feel?" Xiaoxiao said, "Miao Tong and I are in the same dormitory. That morning, she seemed a little worried. I thought she was worried about the third mock exam, so I comforted her a few words. As a result, she said that she was too nervous before. Recently, she talked with her parents and teachers and thought that it would be fine if she performed normally. She has let it go." "

Her attitude is very positive?" He asked carefully.

Xiaoxiao nodded repeatedly: "Yes, she doesn't look like she wants to commit suicide at all. We also said that we would go out to play after the exam."

Ji Feng pondered.

"What's going on?" Ji Yunyun couldn't hold back her temper and urged him, "You've been checking for a long time, do you have any results?"

Ji Feng said with a "tsk", "The suicide note, the handwriting is all her own, how do you explain this?"

Xiaoxiao boldly guessed: "Imitation?"

"Or copied from the homework book or test paper." Ji Yunyun diverged his thoughts.

Ji Feng was more patient than ever before: "Handwriting identification is a professional skill. Simply put, although people can actively imitate other people's handwriting, writing activities are automatic. Unless you strictly control every stroke, you will definitely expose your habits.

"Secondly, even if you can perfectly imitate her original handwriting, the words written under different conditions will definitely be different. Are the words on your test papers smaller and those in your diary larger? Put together, the size and layout will be inconsistent.

"Also, everyone's vocabulary and language habits are different. Of course, you are all high school students, so your words may not look too different, but there is also the stroke order. Words that look similar will have different stroke orders under a microscope."

He concluded: "Handwriting identification generally won't make mistakes. The suicide note was written by Miao Tong herself."

"Ah..." Ji Yunyun looked at a loss, and asked hesitantly, "Then, did she really commit suicide?"

"We can't draw a conclusion now." Ji Feng said, and then changed the subject. "It has nothing to do with you. Eat, and then go back to class. I asked your class teacher, and she said that it would be difficult for you to get the grades you want on the key points. Can you try harder and learn from me?"

Ji Yunyun: QAQ

Her brother is so mean and mean. He actually went to college when he was the top student. It makes me so angry.
