In Changshui Town, Li Yifan and the others have been living comfortably here for seven days.

On the second day of Li Yifan's arrival, he and Zhao Xin'er met Sister Lin, compared to Sister Lin, who was not very calm the first time, she would be much quieter.

The two of them and Sister Lin found the school where Sister Lin's daughter Yaya used to go to school, and even found a teacher in Yaya's class three years ago. A female teacher who is a little fat and not very good-looking, Teacher Zhang.

"Speaking of what happened to Yaya three years ago, I'm also deeply sorry, that time Yaya's mother Sister Lin came to me, to be honest, in addition to Teacher Wu in school, maybe I was closer to this little girl, or no matter how you let me recall, I don't remember anything strange happening at that time." Teacher Zhang shook his head and said helplessly.

"Haven't you noticed anything strange in your years here, like some girls in your class suddenly being called to the office by the principal at night, or suddenly wearing new clothes the next day?" Han Shuo asked all the things that Xiao Yue had mentioned before.

"To be honest, in rural schools like ours, there are few teachers and they change quickly, and the teachers who are usually assigned here will find a way to fall back to the urban school after three to five years. The same is true of the principal, who always changes after a few years, and I have never seen this phenomenon you mentioned. Teacher Zhang continued to shake his head and said.

"How so? Haven't you ever had it once? Li Yifan continued to ask in disbelief.

"If you want to say that there are teachers who teach students to go to the office, but it's normal, and I won't see students come back where it's bad, and I occasionally keep students because of their learning regression or poor homework." Teacher Zhang replied.

"Did you also stay with some teacher before Yaya got sick?" Li Yifan continued to ask.

"I really can't remember, we don't have many students, it's good to be able to get together 30 people in a class, and the students are still gathered in the surrounding villages, and there are many students like Yaya whose parents go out to work, or who stay in school too far away.

It is possible for students to be called to the principal's office or office at this time, but the teachers on duty are different every day, and who knows who will keep them. Under Li Yifan's repeated questioning, Teacher Zhang carefully recalled the events of the past three years, especially what might have happened in the school before Yaya fell ill and left the school three years ago.

Li Yifan didn't tell Teacher Zhang what happened to some girls in their school, but just repeatedly asked the teacher about unusual things in the school.

This kind of question is slower, but only in this way can Teacher Zhao carefully recall what happened to Yaya in school on that night three years ago?

"Who was the teacher on duty at the school on the night of the girl's accident?" Zhao Xin'er asked Teacher Zhang, and she could see in her heart that the teacher was not lying, but her memories were relatively slow, and everything was recalled little by little.

"Well...... It should be Mr. Wu. Teacher Zhang thought for a while, and said after calculating the schedule time of the teachers in the class during that time.

The next day after Yaya had a fever, she was sent to the hospital in the town by the school, and it was already the afternoon of the next day when Sister Lin and her husband rushed back from the city.

But it was still a step too late, after the doctor in the city did a comprehensive examination of Yaya, and Yaya kept muttering before her death: "It hurts, Mom, I hurt, my stomach hurts......" Sister Lin knew that someone had done something inferior to her daughter, who was only in the fourth grade of primary school.

After burying Yaya, Sister Lin found the school and wanted to have an explanation for this matter, but the school pushed everything away, and said that it was because Sister Lin and his husband had not been with her daughter for a long time, and her daughter did not know about her precocious puberty, and she didn't know who she was having trouble with.

Sister Lin found the police and called the police, but in the end there was nothing to do, until she found Mr. Wu, whom her daughter mentioned at the time, and Mr. Wu patiently enlightened her.

When she heard Wu Lianchi's name, Sister Lin's emotions were a little out of control, she kept rubbing her hands and shaking, Zhao Xin'er hurriedly took out the medicine from her bag and handed it to Sister Lin and asked her to take it.

"Is she alright?" Teacher Zhang asked about Sister Lin's situation with concern.

"It's fine." Zhao Xin'er said.

"Actually, you just said that you came to school in new clothes the next day, but I have encountered it, and it should be the time before and after the accident with Yaya." Teacher Zhang suddenly thought of Li Yifan, as they mentioned earlier, wearing new clothes to school during the Chinese New Year or holidays. "There is indeed such a person."

"Remember who it is?" Zhao Xin'er asked.

"It should be a girl in Gaona Village, it seems to be called Gao Xiaohong." Teacher Zhang said recallingly.

"Think about it for yourself, have you ever encountered such a thing in the past few years?" When the teacher squeezed toothpaste in front of her, several people had to ask her to think more about whether there was anything missing.

"There shouldn't be any, or leave a phone number, and if I'm thinking of something, I'll call you." Teacher Zhang offered to leave the phone, and several people left the phone and prepared to leave the school.

"Three years ago, did Du Jianguo come to you to be the principal?" Zhao Xin'er suddenly asked before going out.

"At that time, he was no longer the principal, but just hung up on a position, and when he was sent to us, he should have been in business for a while, and I only found out later." Teacher Zhang said.

On the morning of the fifth day in Changshui Town, Li Yifan finished collecting and drawing small samples ahead of schedule. Early in the morning, he asked Ana about the village of Gaona.

"Why are you going to Gaona Village? There are indeed a few places there that are quite good, but they are quite far away, and the people there are not very good, so I still don't mind you going. Ana pouted and shook her head, not minding that Li Yifan and Zhao Xin'er went there.

"Sister Ana, we really want to go there, you just tell us how to get there." Zhao Xin'er looked at Ana and said coquettishly.

"Okay, I'm really convinced of you, you turn over the map I gave you, look to the north, there is a map of the link between the village and the town, we have the closest town here, here, Gaona Village is here, on the other end, you have to go to the town to find someone's motorcycle, take you over, it's faster, it's only five yuan per person." Ana pointed to the map and told them.

Originally, Li Yifan wanted to check the mobile phone and go there by himself, but there were really too few people there, and the mobile phone showed that they had to go back and forth for more than a day, so Li Yifan gave up decisively, and came to ask the owner of the homestay, Ana, better.
