When Cong Zhijun saw that Chen Xiaoyan's seriously ill parents were still serving the injured Chen Xiaoyan, he told Chen Xiaoyan to recuperate well and honor his parents in the future. also left 300 yuan, although Chen Xiaoyan's parents did not take it, Cong Zhijun secretly put the 300 yuan next to Chen Xiaoyan's pillow.

"I understand your mood at the time, you know that Cong Zhijun is sincere to you, but the sprout of emotions you burst out is distorted, right?" Liu Yi tried to start peeking into Chen Xiaoyan's heart.

Chen Xiaoyan nodded, "It stands to reason that I had lost confidence in men at that time, no one was sincere to me, and I couldn't go to the bar to work at all during my hospitalization, so I was anxious, and the three hundred yuan helped our family solve a lot of problems." ”

Not long after Chen Xiaoyan was discharged from the hospital, Wang Rui found Chen Xiaoyan because Wang Shuang failed to seduce Cong Zhijun. Wang Rui put 100 yuan in front of Chen Xiaoyan, saying that he would make up 100 yuan after the matter was completed, Chen Xiaoyan was short of money at that time, so he agreed, and besides, he was no one else, he was the hero in his heart. But she wanted Wang Rui to keep it secret, otherwise she would tell the whole thing.

One night of self-study, Chen Xiaoyan took advantage of her headache to return to the dormitory first, she sneaked into Cong Zhijun's dormitory, took off her clothes, and stood in front of Cong Zhijun. Cong Zhijun refused on the spot, and left the dormitory, saying a word before leaving.

"He said I had disappointed him too much, what was wrong with me? I already have feelings for him, why can't I do that? Chen Xiaoyan still didn't understand why Cong Zhijun decisively rejected her.

"You were a student at the time, Cong Zhijun was a teacher, and what he did was not wrong. It's you who misinterpret the teacher-student relationship. Liu Yi corrected Chen Xiaoyan's attitude. Chen Xiaoyan didn't say a word, and lowered her head silently.

Liu Yi continued: "If you are willing to talk about the process of that night, I can say it for you!" When Liu saw that Chen Xiaoyan was silent, it should be regarded as a tacit acquiescence. He began to smooth out the entire case, putting the evidence and facts in front of Chen Xiaoyan to make her sober and sober.

At the Christmas party, Wang Rui and Cong Zhijun had a quarrel, Chen Xiaoyan took advantage of the chaos to hide outside the teacher's dormitory building, and when everyone returned to the dormitory, they thought that Chen Xiaoyan had gone to the toilet. Chen Xiaoyan saw that Cong Zhijun had not come back, so in order not to let others find out, she had to go back to the dormitory and then go to the toilet, and so on until Cong Zhijun came back.

"At that time, when the police interrogated, most of the people in your dormitory had already slept, and no one found out how many times you went to the toilet, which is considered lucky!" Liu Yi said.

"I, I didn't mean to kill him, I didn't expect the detergent to kill him!" Chen Xiaoyan suddenly cried bitterly.

"Actually, if Hou Yaojun hadn't dropped the autopsy report, you wouldn't have appeared here until now!" It turned out that the first thing Liu Yi explained to Wang Jianguo was to know Hou Yaojun. When Wang Jianguo searched Hou Yaojun's home, he found multiple autopsy reports in the safe under the bed, which he had forged more than once.

Back then, some liquid was found in Cong Zhijun's stomach, which was tested to be benzalkonium chloride, a cationic detergent that often appeared in the hospital.

"You stole some hospital cleaners while you were in the hospital, didn't you?" Liu Yi asked.

"I didn't know that this thing would kill people, I just brought him a cup of hot water, and then, and then ......" When Chen Xiaoyan appeared in front of Cong Zhijun again, Cong Zhijun was a little disgusted, but Chen Xiaoyan said that he was here to thank him, and poured water for Cong Zhijun with a kettle, and put the benzalkonium chloride prepared in advance in the cup while Cong Zhijun was not paying attention.

"Actually, I admire your luck, if it weren't for the mistake in the construction of the toilet, you wouldn't have been able to dig such a tunnel." Liu Yi said. Chen Xiaoyan glanced at Liu Yi, "I know I'm guilty, but I can't understand why Teacher Cong is a pervert." ”

"You found men's and women's utensils in his dormitory, didn't you? You can't understand?" Liu Yi has always said to Chen Xiaoyan that he was disappointed in Cong Zhijun before.

Chen Xiaoyan nodded, and Liu Yi continued: "He is an adult, this is his privacy, but there is indeed some problem with him bringing this thing to school." Fang Xiaoyun's death was an accident, which makes you happier, doesn't it? Liu Yi sneered and said, this attitude is just like Cong Zhijun treated Chen Xiaoyan back then.

"Can you talk to me in that tone? I, I really, don't know what to do? What I couldn't get, I couldn't let anyone else get, and I couldn't study at all during that time, so I had to go around the store every day just to see him. Chen Xiaoyan's tone was more like a pleading.

Liu Yi thought to himself that normally, it would take one to four hours for benzalkonium chloride to poison a person to death. Because of the temperature, the body's function is greatly weakened, and the liquid is not completely absorbed, and part of it remains in the stomach.

"You're not in a hurry, are you?" Liu Yi understood that it was at this meeting in the dormitory that Cong Zhijun was dead. There are few people living in the teacher's dormitory, and there is no doorman, which is convenient for Chen Xiaoyan to transport the body, Liu Yi has to say that Chen Xiaoyan is really lucky, no one went to the toilet during the whole process.

"I just want to see him more!"

"You found that hole that was remodeled in the water, and you spent the weekend digging it, aren't you tired? And taking off your clothes, transporting corpses, I admire your courage. Wang Jianguo said.

"When the grievances in your heart accumulate too much, they will naturally explode!" Chen Xiaoyan whispered.

"The wooden box under Cong Zhijun's bed was given by you! There must still be a letter in it! Liu Yi suddenly remembered the pile of wooden boxes under Cong Zhijun's bed before.

"Yes, but he won't read it!" Chen Xiaoyan was slightly depressed.

"After you were discovered by Li Ziqi when you left, you kept using money to gag her?" Liu Yi asked. Chen Xiaoyan hurriedly climbed over the wall and left the school, found a public toilet, and began to wash it with cold water. Later, I learned that Li Ziqi saw himself. Liu Yi thought to himself, on such a cold day, a little girl rinsed with cold water. But then I thought that she had killed someone after all, and she did this to cover up her crime.

"Yes, but the income of the supermarket I open is not high, and I have to give her 50,000 yuan a year, and sometimes I have to go to the bar to find some business!" Chen Xiaoyan's original image in Liu Yi's heart collapsed instantly.

"The police have confirmed the economic transactions between you, and everything is true, what about Wang Shuang?" After Li Ziqi told the truth, he immediately sent someone to confirm the matter.

"Wang Shuang has nothing to do with me, Wang Rui often scares her, she was already timid, and then she fell ill." Chen Xiaoyan said.

"This thing is yours!" Liu Yi took out a ziplock bag from his pocket, and inside was a brooch the size of a fingernail with the word Xiaoyan on it.

"It's mine!"

"Hou Yaojun also found this in Cong Zhijun's stomach back then, your principal at the time, Hou Yaojie, in order to protect the reputation of the school and his own status, they colluded to commit perjury, but I didn't expect these people to help you! In order to make Cong Zhijun remember you, you put the brooch in his mouth. After Liu Yi finished speaking, Xu Wei walked in from outside, handed Liu Yi a confession, and whispered a few words in Liu Yi's ear.

Liu nodded and asked, "You became Hou Yaojun's lover?" Liu Yi was taken aback when he saw Hou Yaojun's confession.

Chen Xiaoyan replied in a choked voice: "I have no choice, he forced me!" When Chen Xiaoyan left City C, she suddenly received a call from a strange man, who was Hou Yaojun. It turned out that Hou Yaojun happened to buy a pack of cigarettes in Chen Xiaoyan's store on a business trip.

Unexpectedly, Hou Yaojun happened to recognize Chen Xiaoyan, so he was full of lust and threatened Chen Xiaoyan with evidence. asked Chen Xiaoyan to be his lover, Chen Xiaoyan had to agree.

"I didn't have a choice, and I didn't know he still had evidence in his hands at the time." At this time, the corners of Chen Xiaoyan's eyes were moist.

"Did you just come back to see Cong Zhijun?" Liu Yi hoped in his heart that Chen Xiaoyan would really have a hint of repentance, so that his own heart could be relieved a lot.

"Not only that, I have to thank Hou Yaojun, if he hadn't forced me, I wouldn't have been able to face this matter head-on. The most important thing is you, when you appeared in front of me, I felt as if I saw him, I was really conflicted these days, but finally chose ......"

Liu Yi immediately followed Chen Xiaoyan's words and said: "Chose to kill me too, didn't you?" What you can't get is the same to be destroyed? Liu Yi felt that Chen Xiaoyan should have found that she was deeply in love with Gao Xiaoqing, thinking that she had no chance at all, and she didn't plan to destroy Liu Yi if she couldn't get Liu Yi at all.

"No, no, I, I ......" Chen Xiaoyan was powerless to struggle, at this moment, Liu Yi no longer believed Chen Xiaoyan's words, those were all lies.

"Do you know Guo Dongliang?" Liu Yi asked.

"I know, I sell goods with Mr. Cong, but I'm not as good as Mr. Cong!"

"Do you know he's dead?"

"I heard what others said, but I didn't kill him!" Chen Xiaoyan hurriedly explained.

"I know, this matter has nothing to do with you!" Liu Yi coughed, got up and was about to leave, Chen Xiaoyan saw that Liu didn't look back, her heart was extremely painful, and she felt that she had fallen into an endless black hole all of a sudden.

After Liu Yi walked out of the interrogation room, Wang Jianguo patted Liu Yi on the shoulder, "There is reason and evidence, the case is solved!" Guo Dongliang's death has nothing to do with Chen Xiaoyan, but has something to do with Wang Rui. ”

"Yes, I think Hou Yaojun is the culprit who the police can't solve the case, and he should have something to do with the laboratory department back then." Liu Yi said affirmatively.

"Don't worry, the guilty one won't be able to escape." Wang Jianguo was full of confidence, it turned out that Hou Yaojun found a small amount of anesthetic in Guo Dongliang's stomach, which was not much, but it was enough to make people unconscious for a while. Through Zhang Yang's phone call, Wang Rui did ask Zhang Yang to find some anesthetic medicine for her.

Hou Yaojun knew that Guo Dongliang was a teacher at his brother's school, so he naturally covered it up and made the certificate case an accident.

"Wang Rui will be here in a while!" Xu Wei's voice came from behind Liu Yi.

Liu Yi sat at the door of the Southern District Bureau, smoking all the time, he knew how possessive Chen Xiaoyan was, he touched his neck, and thought to himself, if he hadn't reacted quickly just now, he would have become the second Cong Zhijun by now.

"I heard Brother Wang say that it's coming soon!" Liu Yi threw the cigarette butt into the trash.

"A woman's heart is a needle! Dude, don't think about it so much, she's just a sugar-coated poison, there's nothing to regret! Liu Yi nodded, thinking that Xu Wei had a point, and then stood up and said, "Let's go!" I have to interrogate Wang Rui in a while, but I didn't expect us to crack three cases at once! ”

"Yes! I don't think the North District Bureau will dare to swish in front of us again. Xu Wei said angrily.

"Let's go!" Liu Yi patted Xu Wei on the shoulder, and the two returned to the police station together.
