The preliminary autopsy was soon completed. The cause of Zhou Guoqiang's death is self-evident, Wu Changan died of a sudden heart disease or other reasons, pending further autopsy.

It was noon. Wu Ping's questioning work was nearing completion, and experience told him that the murderer was not among the students or parents, and he was ready to ask the leaders for instructions to allow the students and parents to leave the school. Such a noisy and chaotic environment cannot activate keen observation and correct judgment.

When the teachers, students, and parents who had been invited to watch the opening ceremony left, the whole campus suddenly fell silent. This dead silence is accentuated by the occasional motorcycle passing on the road outside the school walls, the shouting of farmers plowing the fields behind the buttocks of the ploughing oxen, the sound of the cows whipping their backs with hemp ropes, and even the cries of birds that suddenly sweep over the school.

It's a terrible quiet.

Now, the leaders and case-handling personnel who stayed behind are concentrated in the canteen to eat. The case must be investigated, and the food must be eaten. Xu You, Yu Chili, and other single teachers who lived in the school sat around another table. The meal was already packed, but not in the mood to eat it. It was the first time in each of their lives that they had come close to death.

After lunch, Wei Chili was arranged by the school to go to Wu Changan's house to accompany his wife. At the very least, she needs the company and comfort of an acquaintance or a loved one today, or for a long time to come.

Xu You straightened out his inner world a little. He was sure that the killing of Wu Chang'an had not been discovered by anyone, and that such a sudden death, coupled with the destruction of the rice paper that had caused Wu Chang'an's poisoning, would not be easy to associate with the three words ***. The most important thing is that Wu Changan died at the same time as Zhou Guoqiang, so it is easy for the criminal investigators to merge the two cases, so everything will cover up a lot of clues that should have been paid attention to in Wu Changan.

Xu You believes that the police will not be able to find him for the time being, at least not so quickly. So he still has a lot of time to investigate the mistakes he may have made and remedy them in time. What really disturbed and puzzled him was: Zhou Guoqiang's death. Who killed him, why did he kill him, and why did it happen at the same time that he killed Wu Changan. Is it just a coincidence? It's just a coincidence, if not, wouldn't the murderer already know about his poisoning of Wu Changan.

Thinking of this, Xu You felt a chill down his spine. He couldn't eat, so he hurriedly washed the dishes and went to the place designated by Wu Ping in advance. At this time, it is not strange that people can't eat, and many people can't eat.

After Xu You sat down on the stool outside the door, others also arrived one after another.

Soon, Wu Ping, the captain of the criminal police brigade, also arrived, followed by two police officers.

Xu You was questioned first.

Although I was mentally prepared, I was still nervous. It is natural to be a thief, and Xu Yu tries his best to control and adjust his emotions.

"Name, age, identity, place of origin......" Wu Ping asked straight to the point.

"Xu You, 25 years old, teacher, hometown in Zi County."

Wu Ping lit a cigarette, took a deep breath, and raised his head to look at Xu You.

His fair complexion, slender and healthy body, and fluent Mandarin without a local accent make it easy for Xu You to distinguish himself from others.

Wu Ping continued, "If I'm not mistaken, Zi County is not less than 500 kilometers away from Guangong Town, how did Teacher Xu think of coming to teach so far away?" ”

"Yes, 502 km to be exact. I've been further afield before, so it doesn't seem that far away. ”

"Has Mr. Xu ever got married?"

"Alone."

"Oh." Wu Ping spat out the smoke in his mouth and stared at Xu You's eyes, as if he wanted to see something in his eyes, Wu Ping felt that the person in front of him was different.

"When did Teacher Xu come to Guangong Town, and where did he go to high school before this?" Wu Ping continued to ask.

"A month ago, on March 26, I used to teach high school math and geography at my hometown Zixian Middle School." Aside from answering the necessary information, Xu Yu didn't want to say anything more. The more you say, the easier it is to make mistakes. He wanted to end the questioning quickly, even if the initiative was pinched in the hands of the other party.

"Oh. Did Mr. Xu encounter difficulties in Zi County? ”

"Nope. Everything is going well, why did Captain Wu ask like this. Xu Yu also looked at Wu Ping's eyes. Wu Ping's eyes are like two lightning bolts, clear and bright, as if they are about to pierce your heart. Xu You's heart was shocked, and he didn't dare to continue looking, so he hurriedly looked away. Wu Ping is really an old Jianghu, and he must be extra careful to deal with it next.

"Teacher Xu, don't be nervous, I'll just ask casually, just like chatting about family life. According to my understanding, Zixian County is Mr. Xu's hometown, and teaching high school should have a higher salary than teaching junior high school. These three factors add up, I think, unless Mr. Xu, you are in trouble in Zi County. Obviously, Wu Ping was not satisfied with the conversation between the two men at the beginning, at least, the answer "I have been further away before" did not satisfy him. He deliberately brought the conversation back to the question of why Xu You left Zixian County and insisted on teaching in Guangong Town. The answer to this question, he believes, is important.

"After my mother passed away, there were no relatives in my hometown in Zixian County. I want to leave that city, please forgive me for my weakness. Xu You buried his head deep in his chest, and he felt that he had acted very well.

"Where's my father?"

"My father passed away many years ago, I just remember, when I was very young."

"I'm sorry. Teacher Xu, I reminded you of something sad. It was inconvenient for Wu Ping to continue to ask on this topic, "Principal Zhou or Director Wu, which one is more familiar with Teacher Xu?" ”

"I usually focus on the course, and I don't have much time to contact the leaders, and I don't know the two very well. If you must make a comparison, be familiar with Director Wu. ”

"Oh? How to say. Wu Ping asked with interest.

"I went to Director Wu's house for dinner and ran with him." Xu You shot his gaze into the distance and sighed, "People have good and bad luck, I really didn't expect it...... Director Wu is a good person. Captain Wu must catch the murderer for us. ”

Wu Ping had already finished smoking his second cigarette. He dropped the cigarette butt on the ground and snuffed it out with his toes. Smoking is Wu Ping's only hobby, but he is not willing to share this hobby with others, and when he smokes, he never cares about the people next to him, let alone gives cigarettes to others. Now, he has lit the third.

The smoke coming out of the tip of the cigarette and the smoke coming out of Wu Ping's mouth mixed together, gradually enveloping the interrogation room in a thick cloud of smoke. Xu You couldn't help coughing. "Teacher Xu doesn't smoke? I'm sorry, when I talk to people, I can't help but smoke, and if I don't smoke, my mind is not clear. Wu Ping exhaled another puff of smoke.

"It's okay......" Xu You smokes, but he doesn't smoke often, at least, it's not addictive. Everything that is addictive can become a person's weakness and, sometimes, fatal. At this point, Xu Yu was grateful for the clouds of smoke in the interrogation room, which could hide his occasional uneasiness. "Eat...... Jogging...... They should be very familiar with each other, how can Mr. Xu say that they are not familiar? Wu Ping felt that Xu Yu was deliberately hiding something.

"Compared with President Zhou, my relationship with Director Wu is closer, but I am not very familiar with it......," Xu You briefly explained how to go to Wu Chang'an's house for dinner and how to run together.

"What do you think about the deaths of Principal Zhou and Director Wu?"

"This question is stumped on me, I can only teach, and I don't know anything about investigating cases."

"Talk about your intuition, how much you say."

"This ...... If I have to say, judging from the situation at the scene, Principal Zhou was killed; As for Director Wu...... Director Wu, did you die of a heart attack or other illness caused by fright? ”

The policeman who made the record tapped a few times on the table with his pen, "Teacher Xu, the captain is asking your opinion, not that you are asking us......" Wu Ping waved his hand to stop him, "Teacher Xu, your idea is very right, I think so too." Let's talk about something else, like, what strangers have been to the school recently? Or, what did President Zhou and Director Wu behave differently from usual? ”

Xu You shook his head, "Strangers, there are some, but I don't have much impression." As for the abnormal behavior of Principal Zhou and Director Wu, Captain Wu is afraid that he will have to ask their families to find out better. ”

"Okay. That's all, thank you for your cooperation. ”

"I'm sorry I can't provide you with anything useful." Xu You got up and walked out of the door.

After Xu You left, Wu Ping grabbed his chin with his hand for a long time, "Do you feel that there is something wrong with this Teacher Xu?" But I can't say what it is. ”

"Wu team, what should I do next?" The police officer who made the transcript asked.

"Keep asking." Wu Ping's words already reflected irritability and restlessness, and he felt that Xu Yu had a lot of unpredictable things. He lit a fourth cigarette.

The subsequent questioning went quickly according to the process. The police were not given much useful for the progress of the case.

Xu You let out a long sigh of relief after coming out of the inquiry room. Before poisoning Wu Changan, he had already imagined countless times all the investigations, inquiries, and consequences that he might encounter after the killing. Although well prepared, it was the first time to kill after all. The first time anyone does something, it is inevitable that they will be nervous, excited, and even out of control. The first time I gave a speech on stage, the first time I drove a car, and the first time I kissed a woman's small mouth.

Survive the first hurdle safely.
