"Hey, teacher, it's me, I'm Li'er's mother..." Jialiwen's face was full of worry: "It's like this... Last time we were talking to me, you told me that there was a child in the class like Li'er, saying that there was a friend who no one else could see. Is this true?"

"Yes, that child did say that, but that was a good child. Is there any problem?"

"No, I want to ask if that child has any contact information."

“I have his parent contact information.”

"Can you give me his parents' contact information?"

"Okay, you wait."

Soon, Jialiwen got the contact information. After hanging up the teacher's phone number, Jialiwen called the child's parents again.

"Hello, are you Xiaobin's mother?"

"Yes, who are you?"

"I am the mother of Xiaobin's classmate Li Er."

"Hello, is there anything you have?"

"Is Xiaobin here? I have something to ask Xiaobin, it's about Li'er."

"Xiaobin is in the hospital now."

"Hospital? Has he entered the hospital?" Jialiwen's heart skipped a beat and she secretly screamed that something was wrong.

"Just yesterday, Xiaobin didn't know what was going on, lying on the bed without moving, just opening his eyes like that..."

Xiaobin's mother's voice on the phone was full of fatigue and worry, just like Jialiwen.

Jialiwen's mood also became heavier with Xiaobin's mother's holy seal.

After a few words of comfort, Jialiwen hung up the phone.

"How about it?"

"Li'er's classmate Xiaobin, he also had an accident, and his symptoms were exactly the same as Li'er, and he had an accident one day earlier than Li'er." Jialiwen became more and more anxious and almost cried: "Bai Chen, what should I do? You must have a solution, right?"

Bai Chen's face was solemn: "Don't worry, let's analyze it and see if we can find useful clues."

"Is there any clue?" Jialiwen was almost desperate. For her, Li'er was everything, but now Li'er has become like that, and as a mother, she is helpless.

Jialiwen's face was buried in her hands, crying silently, she had already thought about the worst.

"Listen to me! If you still want to save your daughter!" Bai Chen shouted softly.

Jialiwen looked up at Bai Chen: "Is there still hope?"

"I don't know, but I have to work hard, even if there is only a glimmer of hope, are you willing to give up like this? Let Li'er lie in the hospital like a living dead?"

"Yes... there is still hope, I will not give up, I will not give up!" Jialiwen seemed to be encouraging herself.

Bai Chen looked at Jialiwen and analyzed: "Generally speaking, people's eyes are called Yin and Yang eyes."

"What is Yin and Yang Eye?"

"I can't explain clearly and I don't have time to explain. Let me continue." Bai Chen paused and continued: "The probability of Yin and Yang Eyes is very small, just like a rare blood type. There may be only Yin and Yang Eyes among millions, and how many people are in Li'er's class?"

"Thirty people." Jialiwen replied.

"Thirty people, two yin and yang eyes appeared in one million. How small is this probability? What a coincidence? So I think it is not that Li'er and her classmate Xiaobin have yin and yang eyes, but that the ghost chose them so that they could see their existence."

"Then what?"

Jialiwen held her breath and looked at Bai Chen with a trembling gaze, waiting for Bai Chen to continue to analyze.

"What did Xiaobin and Li'er kill in common?"

“Do they have something in common?”

"For example, identity is the common point." Bai Chen thought for a while and said, "The people they contact on weekdays will also have common points, such as classmates and teachers."

"And their classmates are basically all peers, so they can be ruled out, so the next one is the teacher, so the teacher is the most likely."

"Can it be her responsible teacher? It's the one I called just now..." Jialiwen began to worry again. If it was the one I called just now, then the other party might be suspicious. What if the other party destroys evidence? What if the other party hurts Li'er?

"What is that teacher?"

"Her name is Susan..."

"Susan?" Bai Chen raised his eyebrows: "Tell me her phone number."

"Is it her?" Jialiwen was shocked when she saw Bai Chen's expression.

"She is my neighbor. I have contacted her and visited her home, so she should not be the mastermind."

"Isn't it her? What should I do? Is it another teacher?"

"Since I can be sure she is not the mastermind, then look for her, maybe she can provide us with more clues."

"Yes, she has been in school and has more time to contact Li'er than me, so she can definitely provide clues." Jialiwen immediately raised hope when she heard Bai Chen's words.

Carrievin is like a drowning person, seizing everything she feels is possible.

"Teacher Susan, it's me, Li'er's mother. I'm sorry to disturb you. Do you have time? I need to talk to you in person. Now, yes, now... things are more urgent. OK. At the Xin'an Beverage Store on No. 2 Xin'an Street, you can."

Jialiwen looked at Bai Chen: "I have made an appointment."

"Then let's go now."

Originally, Bai Chen didn't want to come forward, but at this time Jialiwen was already in vain. I'm afraid she wouldn't be able to ask anything just by relying on her. And Bai Chen also needs to ask some questions in person.

The two drove to the agreed location, and half an hour later, Susan also arrived.

However, when Susan entered the store, she found that Jialiwen and Bai Chen were sitting together, and she couldn't help but walk forward curiously.

"Xiaobai, why are you here too? Do you know Ms. Carriewen?"

Jialiwen stood up with a haggard face: "Hello, Teacher Susan."

"Sit down." Bai Chen nodded, and did not answer Susan's previous question.

Susan discovered that Bai Chen was not joking with her very rarely, and Susan's expression also seemed particularly haggard and solemn.

"Ms. Carrievin, are you uncomfortable?"

"Sister Susan, I have a few questions to ask you."

Susan looked at Bai Chen and looked at Jialiwen with inquiring eyes. Jialiwen nodded: "It's Bai Chen who wants to ask you a question."

"Teacher Susan, what are you teaching?"

"Mathematics, Xiaobai, are you planning to go to school?"

Bai Chen smiled faintly and shook his head: "Li'er, you know."

"I know, my student."

"Can you tell me about Li'er's situation at school?"

"Xiaobai, do you know Li'er?"

"I know her."

"Li'er is a very well-behaved girl..." Susan's answer belongs to the teacher's standard answer, especially when facing parents, no teacher will tell the parents that your child is a bad child.

It can be seen from Susan's answer that Susan is quite the person in charge. Jialiwen, who was standing beside him, nodded repeatedly after hearing this, as if she had forgotten about Li Er's affairs, was immersed in it and couldn't extricate herself.

However, Bai Chen interrupted Susan: "Sister Susan, what I want to hear is not this. Who is Li'er getting closer to in the class? Which teacher do you have more contact with?"

"Li'er has many friends in the class, and basically maintains a good relationship with every student. If I say that the one who plays the best, I don't know. However, Li'er and Xiaobin have been very close recently. Xiaobai, what are you doing? "

"Does there anything unusual about them?"

When Susan heard Bai Chen’s question, she was already suspicious because Bai Chen’s question was like a police interrogation.

"Xiaobai, tell me honestly, is there something wrong with Li'er?"

"She's in the hospital now."

"What? What's going on?" Susan suddenly stood up.

"Sit down."

"what is going on?"

"Li'er is poisoned." Bai Chen made up an excuse and replied.

"Who did it?"

"We are still investigating now, so we want to ask if we can get some useful clues from you."

"You are suspicious that the person who poisoned them was a student in the school? Or... a teacher?"

“There are doubts about this.”

"So have you found the suspect?"

"No, the police have no clues, so we need to find clues from you, the responsible teacher."

Susan looked at Bai Chen and Jialiwen with a wry smile: "Am I also your suspicion?"

"If you are our suspicion, you won't come to talk to you here."
