On December 6, the technical department worked overtime to do the inspection, and Ying Mingyu and they sorted out the information they got back.

They obtained a roster of students in their class, as well as the rosters of three other classes of the same major, and circled the names of people to be checked based on the information they had asked during the day.

In the second half of the night, the technical department came to inform the results that toxin S was detected in the bottled water of the two dormitories, and the content was very high. No toxins were found in other foods, and it was almost certain that this was the location of the poisoning.

"This is most likely a case of human poisoning, and the murderer is someone who can go to their two dormitories, and it may not be alone...... But if such a coincidence is coincidental, could it be a conspiracy between a man and a woman?"

"It's also possible that the person who delivered the bottled water was poisoned, could it?"

"Then it depends on whether they ordered the bottled water at the same house, and whether the person who delivered the water was the same person. ”

"Are you making up stories or writing novels, how can there be such a thing, the water seller is psychopathic and wants to poison college students?"

"Okay, don't go too far, as usual, we have to investigate, tomorrow Da Zhuang and the nail will go to meet, and then go back to the school to meet. Ying Mingyu was afraid that they would have a tea party, so he interrupted the conversation.

"Yes, Boss. ”

"Having said that, I don't think the murderers will be two people, although the S content in the two buckets of water is different, but the converted dose is actually the same, and the percentage difference is because the capacity of the water is different. Ying Mingyu, who had the most words, appeared, "If two people partner to poison, the dosage of the medicine will not be the same, assuming that two people partner but let one person take the medicine, the pressure is all on one person, which is also difficult to say." ”

"That'...... The two people did not conspire and coincidentally did it on the same day?"

Liu Minmin interjected, "What, according to me, it's a person at all, and it must be a girl, and poisoning is originally a woman's patent." ”

"Your instincts have flare up again?" Da Zhuang said to her.

"It's not intuition, I'm reasoning according to Master's train of thought. How could two people who did not conspire to poison the same person and still use the same dose on the same day? It must be one person who committed the crime independently, and in this case, the probability of a woman is obviously greater than that of a man. ”

Ying Mingyu coughed, "It should be a female student who committed the crime independently." The focus is on the girls in their class, eight people in the two dormitories next door, and it is not excluded that four people were poisoned in this dormitory. ”

"Agreed, according to the preliminary inquiry, they don't have much friendship with the senior sisters and sisters of other grades, at most, Liang Qiuping is working in the student union, and there will be some intersections, and you can ask her when she wakes up. Fang Jinshi expressed his opinion smoothly.

"Boss, all four of them in the dormitory were poisoned, could it be that they poisoned themselves?" Ding Yuan felt that this was too scheming, was a little girl in her early twenties so cunning?

"Although it is unlikely, it cannot be completely ruled out. Ying Mingyu is very cautious.

"Understood. ”

"I hope Liang Qiuping and Ding Jingmin will wake up tomorrow, they will be needed for many problems. ”

"Tomorrow, Sister Fang and Baozi will go to the hospital to make up the confession, it is estimated that the two will wake up, the first two to wake up have been discharged from the hospital today, and it is estimated that the other two will also be discharged tomorrow. ”

"Master, what about me?" Liu Minmin struggled for work.

Ying Mingyu glanced at her, "Come with me to school tomorrow and talk to Mo Qingling and Sun Yayan." ”

"Really, Master?" Liu Minmin's eyes lit up suddenly.

"Okay, disband, split up tomorrow. ”

"Master, what time will you come tomorrow?" Liu Minmin immediately glued on.

"I'll pick you up at eight o'clock. "Ying Mingyu has a car anyway, "I didn't pass the physical acceptance, so I will continue next time." ”

"Oh......" Liu Minmin thought that the master took her to the front line, putting aside this matter and planning to protect her closely.

From the end of October to the end of November, she challenged three times, and even if she didn't pass the assessment, she still had a kind of despair that she couldn't overcome her master. She didn't plan to really win against Master, but it seemed difficult for him to say that he was qualified.

Ying Mingyu took her with him for this reason, he was afraid that this girl would be as easy to cause trouble as Qianqian, and he couldn't protect herself, and he was also afraid that this girl would make her own ideas and have no organizational discipline, and others would not be able to guarantee that she would not run away.

Ding Yuan and Da Zhuang went to find the shop that delivered water to the school early in the morning, they opened early, and they sent the men's and women's dormitories. However, they also have people, the men's dormitory is sent by male employees, and the female dormitory is female employees, otherwise they can't go up.

They sent out hundreds of buckets of water these days, and there was no problem, and the staff didn't know a few students at all, and the names they could say were all lively students who liked to make friends, not including the victims this time.

In addition, the water they send is sealed, the bucket is of good quality, it is impossible to prick the needle, and the plastic paper on the top is torn open, and there is a very thick press cover, which cannot be used for hands and feet.

After completely ruling out suspicions, the two walked to the school to meet Ying Mingyu and Liu Minmin.

After Fang Jinshi and Bao Zhan arrived at the hospital, they knew that Ding Jingmin and Liang Qiuping had woken up last night, and after doing many examinations, they were undergoing treatment and rehabilitation, and they could be questioned in the morning.

The two immediately went to disturb Ding Jingmin, who may be the central figure in this case.

"It must be Liu Yiyi, she also taunted me with Chen Xiaoxiao in their dormitory last night, and she stood at the entrance of our dormitory. ”

After talking about his schedule the day before yesterday, Ding Jingmin insisted that the murderer was his ex-girlfriend.

Bao Zhan couldn't help but think, what kind of grudge is this, and the boyfriend and girlfriend who broke up can't look down on each other so much?

"Then do you have a good relationship with the boys in the same dormitory and other dormitories?"

"Changlin and I both go to and from class normally, and occasionally team up with them to play a game, and there are no people who don't get along. ”

"You should be very attractive to girls, doesn't anyone hate you because of this?" Fang Jinshi didn't care about praising the boy in front of him.

Ding Jingmin blushed a little, but still said, "When I was with Liu Yiyi before, there were some people who didn't want to see me, mainly because they also liked Liu Yiyi, and now that we are separated, I have a good time with Shu Yi, they can't ask for it, what is there to worry about." ”

That makes sense, but Bao Zhan then asked, "Then aren't there one or two who like to be comfortable and start looking for your faults?"

"I don't know for the time being, but isn't Shu Yi also poisoned, is he so ruthless, if he can't get it, he will destroy her?"

They haven't been together for long, and that's probably true.

"Okay, you have a good rest, we'll all talk after a while, Shuyi should come to see you. ”

Liang Qiuping is a girl after all, and her physique is weaker, although she wakes up, it is much harder to speak than Ding Jingmin.

"I really don't understand, how could someone poison us?"

They just started to tell her that it was artificially poisoned, and Liang Qiuping burst into tears with red eyes.

As far as sensuality is concerned, this girl is shallow on the land, and Bao Zhan is talking to herself in the bottom of her heart.

"Do you have a feud with anyone in the student union?"

Liang Qiuping shook her head, "I usually try to help persuade as much as possible, even if I can't please him, I won't be hated, right?"

This is in line with what the other three people in the dormitory said about her, including Liu Yiyi and Chen Xiaoxiao, although Liang Qiuping said two bad words, but they all called her nickname, and they didn't seem to really dislike her.

"Do you remember who came to your dormitory the day before yesterday?"

Liang Qiuping thought for a while, "There were only one or two classes that day, and we had a stomachache before the last two classes in the afternoon...... The break is very long, I went back with Yiyi at lunch, I don't know in the morning, and the dormitory next door has come to play in the afternoon, it seems that Pan Li is opposite, and who is next door, to find Shu Yi should be. ”

"If you think of anything else, just let the nurse call us. ”

The two went out and checked the information nearby, "It seems that Liang Qiuping is unlikely to be the target of the murder, she should have been injured by mistake." ”

"This kid is really unlucky. Bao Zhan sighed.

"Okay, let's go and ask Liu Yiyi and Shu Yi again, have they noticed who has approached the bottled water, and they are almost going to the school to meet the two who have been discharged, and they will meet the team. ”

Shu Yi provided the names of classmates who had come to their dormitory to chat with her, but more had come the night before, including the class officials who had informed them that they were going to start handing in their lab reports.

Because they hurriedly went to morning class early on the fifth day, except for Shuyi who drank a carton of pure milk, the others did not drink water at all, and the possibility of being poisoned the night before could not be ruled out.

After Ying Mingyu and Liu Minmin arrived at the school, they quickly found Mo Qingling and Sun Yayan separately, and ruled out the latter without a few words.

Sun Yayan hates everyone in this dormitory, mainly Liang Qiuping and Shu Yi, and secondly, she doesn't like Liu Yiyi, who thinks she is beautiful, and Chen Xiaoxiao, who loves to sell stinky money, so she has never been to their dormitory.

"It's disgusting enough to stand in the doorway, and still go in?"

Mo Qingling has a good relationship with Liang Qiuping, she said that she had been in the night before and that afternoon, but she just went to talk to Qiuping, and she didn't know anything else.

Considering that these two girls have a relationship, it is a bit illogical for her to poison and hurt her best friend.

There are twelve girls in this class, and there are three dormitories, and after these two people asked, they checked half of them.

After Da Zhuang and Ding Yuan came over, they had already asked the other six people one after another, two of them happened to have never been to 501 before and on the day of the crime, and three of them had a good relationship with Shu Yi, Liu Yiyi, and Liang Qiuping, so they often went to play, and the motive was doubtful, and the rest was more introverted and had no friends, but did not hate anyone.

After Bao Zhan and Fang Jinshi arrived, Chen Changlin and Chen Xiaoxiao from the hospital asked a few questions, and they said similar things to others.

"I went to the boys' dormitory with Yiyi the night before and said a few words about Ding Jingmin, but we didn't specifically scold him, we just went to the dormitory next door to find a classmate to do experiments together, by the way. ”

Chen Xiaoxiao admitted what Ding Jingmin reflected, and also assured that Liu Yiyi had not approached the bottled water.

"We didn't drink water from them, we didn't touch the bucket of water at all!"

After sifting it out, no one seemed suspicious.
