On December 6, the technical department worked overtime to conduct inspections, while Ying Mingyu and the others sorted out the information they got back.

They got the roster of students in their class, as well as the rosters of three other classes in the same major and at the same level, and based on the inquiries during the day, they circled some names to be investigated.

In the middle of the night, the technical department came to notify me of the results. Toxin S was detected in the bottled water in the two dormitories, and the content was very high. No toxin was found in other foods, and it was basically certain that this was the location of the poisoning.

"There is a high probability that this is a case of man-made poisoning. The murderer is someone who can go to their two dormitories. It may not be the same person... But such a coincidental incident, could it be a conspiracy between a man and a woman?"

"It's also possible that the person delivering the bottled water was poisoned, right?"

"Then we have to check whether they ordered bottled water from the same store, and whether the person who delivered the water is the same person."

"Are you making up a story or writing a novel? How can there be such a thing? The water seller has a psychopath and wants to poison college students?"

"Okay, don't go too far. We're going to investigate as usual. Da Zhuang and Ding Dian will follow us tomorrow and we'll meet back at school afterward." Ying Mingyu interrupted because he was afraid that they would have a tea party.

"Yes, boss."

"Come back, I don't think the murderer could be two people. Although the S content in the two buckets of water is different, the converted dose is actually the same. The difference in percentage is because the capacity of the water is different." Ying Mingyu, the most talkative person, appeared on the stage, "If the two

If individuals collaborate to poison, the dosage of the medicine will not be the same. If two people collaborate and let one person get the medicine, the pressure will be all on one person, which is difficult to make sense."

"Then...the two of them didn't conspire to do it on the same day by coincidence?"

Classmate Liu Minmin interrupted and said, "What? From my point of view, it's just a person, and it must be a girl. Poisoning is a woman's patent."

"Is your intuition acting up again?" Da Zhuang embarrassed her.

"It's not intuition. I followed Master's reasoning. How could two people poison the same day and use the same dose without collaborating? It must be one person who committed the crime independently. In this case, the probability of women is obviously greater than that of men."

Ying Mingyu coughed, "It should be a female student who committed the crime independently. The focus is on the girls in their class. There are eight people in the two dormitories next door. It cannot be ruled out that the four people in this dormitory were poisoned."

"I agree. According to preliminary inquiries, they don't have much friendship with the seniors in other grades. At most, Liang Qiuping works in the student union, so there will be some intersection. You can ask her when she wakes up." Fang Jinshi expressed his opinion.

.

"Boss, four people in their dormitory were poisoned, maybe they poisoned themselves?" Ding Yuan thought this was too scheming. Can a girl in her early twenties be so cunning?

"Although the possibility is unlikely, this possibility cannot be completely ruled out." Ying Mingyu was very cautious.

"Understood."

"I hope Liang Qiuping and Ding Jingmin can wake up tomorrow. They are needed for many problems."

"Sister Fang and Baozi will go to the hospital tomorrow to record their confessions. It is estimated that the two will wake up. The first two to wake up have been discharged from the hospital today, and the other two are expected to be discharged tomorrow."

"Master, where am I?" Liu Minmin fought for a job.

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

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

"Okay, let's disband and split up tomorrow."

"Master, what time will you be there tomorrow?" Liu Minmin immediately stuck to her.

"I'll pick you up at eight o'clock." Ying Mingyu had a car anyway, so he said, "I didn't pass the physical fitness test. I'll continue next time."

"Oh..." Liu Minmin thought that Master had brought her to the front line to put aside this matter and plan to protect her personally.

From the end of October to the end of November, she challenged three times. Even if she failed to pass the assessment, she still felt hopeless that she could not defeat the master. She did not really intend to defeat the master, but it seemed that it would be difficult to get him to pass the test.

Ying Mingyu took her with him for this reason. He was afraid that this girl would get into trouble as easily as Qianqian and would not be able to protect herself. He was also afraid that this girl would make her own decisions and lack organization and discipline, and others would not be able to guarantee that she would not run away.

Ding Yuan and Da Zhuang went to the store that delivered water to the school early in the morning. They opened early, and they delivered water to the male and female dormitories. However, they also have separate people. Male employees deliver water to the male dormitory, and female employees deliver it to the female dormitory. Otherwise, they go to the school.

Not going.

They have delivered hundreds of buckets of water these days without any problems, and the employees don't know a few students at all. The only names they can name are students who are more lively and like to make friends, not including the victims this time.

In addition, the water they deliver is sealed, and the quality of the water bucket is such that it is impossible to insert a needle. After the plastic paper on the top is torn off, there is still a thick press cover, and it is impossible to tamper with it.

After thoroughly ruling out any suspicion, the two walked to school to meet Ying Mingyu and Liu Minmin.

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

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

"It must be Liu Yiyi. She even teased me a few times with Chen Xiaoxiaolai from their dormitory last night. She was standing at the entrance of our dormitory. You said the poisoning place was in the bottled water, right? Water is

Leave it by the door."

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

Bao Zhan couldn't help but want to be speechless. What kind of hatred or resentment is this? The boyfriend and girlfriend who just broke up couldn't despise each other so much?

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

"Chang Lin and I attend and finish classes normally. We occasionally team up with them to play games. There's no one we don't get along with."

"You should be very popular with girls. Doesn't anyone hate you because of this?" Fang Jinshi didn't care to praise the boy in front of him.

Ding Jingmin blushed a little, but still said, "When I was with Liu Yiyi before, some people didn't want to see me. The main reason is that they also like Liu Yiyi. Now that we are separated, Shu Yi and I are fine together. They can't ask for anything. What's the matter?"

Calculable."

This makes sense, but Bao Zhan then asked, "Then there aren't one or two people who like Shu Yi who start to find trouble with you?"

"I don't know yet, but isn't Shu Yi also poisoned? Is he so ruthless that he will destroy her if he doesn't get it?"

They haven't been together for long, so this is probably true.

"Okay, you have a good rest. We have all asked after a while, and Shu Yi should come to see you."

After all, Liang Qiuping is a girl and has a weaker constitution. Although she is awake, speaking is much more difficult than Ding Jingmin.

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

As soon as they started to tell her that the poisoning was caused by humans, Liang Qiuping's eyes turned red and she shed tears.

In terms of sensibility, this girl is as good as Lu Qianqian, Bao Zhan said to himself in his heart.

"Is there anyone you have a grudge against in the student union?"

Liang Qiuping shook her head, "I usually try my best to help break up fights. Even if I don't get any favors, I won't be hated by others, right?"

This is in line with what the other three people in the dormitory said about her, including Liu Yiyi and Chen Xiaoxiao. Although they said something bad about Liang Qiuping, they all called her by her nickname, and they didn't seem to really have any dislike for her.

"Do you still 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 stomachaches before the last two periods in the afternoon... There was a long break in between. Yiyi and I didn't go back until lunch time. I didn't know in the morning, but next door in the afternoon

Everyone from the dormitory has been here to play, it seems to be Pan Li from across the street, and someone from the next door, it should be Shu Yi."

"If you think of anything else, just ask the nurse to 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 was probably accidentally injured."

"This child is so unlucky." Bao Zhan sighed with emotion.

"Okay, let's ask Liu Yiyi and Shu Yi if they have noticed anyone approaching the bottled water. They are about to go to school to meet the two discharged from the hospital and meet up with the response team."

Shu Yi provided the names of the classmates who came to their dormitory to chat with her, but more people came the night before, including the class cadre who informed them that they were about to start submitting lab reports.

Because they hurried to class early on the 5th, except for Shuyi who drank a carton of pure milk, the others did not drink water at all, so the possibility of being poisoned the night before could not be ruled out.

After Ying Mingyu and Liu Minmin arrived at school, they quickly met Mo Qingling and Sun Yayan alone, and eliminated the latter after a few words of conversation.

Sun Yayan hated everyone in this dormitory, mainly Liang Qiuping and Shu Yi, and secondly she didn't like Liu Yiyi, who thought she was pretty, and Chen Xiaoxiao, who loved to show off her money, so she had never been to their dormitory.

"It's disgusting to stand at the door, why don't you go in?" These were the girl's exact words.

Mo Qingling had a good relationship with Liang Qiuping. She said that she had gone in the night before and that afternoon, but just to talk to Qiuping, and she knew nothing else.

Considering that these two girls are friends, it is a bit illogical for her to poison her best friend.

There are a total of twelve girls in this class, and there are three dormitories. After these two people asked, half of them were checked.

After Da Zhuang and Ding Yuan came over, they briefly asked six other people one after another. Two of them happened to have never been to 501 before and on the day of the incident, and three of them had good relations with Shu Yi, Liu Yiyi, and Liang Qiuping, so they often

I went to play, but my motives were questionable. The other one was more introverted and had no friends, but he didn’t dislike anyone.

After Bao Zhan and Fang Jinshi arrived, they asked Chen Changlin and Chen Xiaoxiao who were in the hospital. What they said was similar to the others.

"Yiyi and I went to the boys' dormitory the night before and said a few words to Ding Jingmin, but we didn't specifically go to scold him. We just went to the next door dormitory to find classmates who were doing experiments together, just by the way."

Chen Xiaoxiao acknowledged what Ding Jingmin reported and assured that Liu Yiyi had never been close to bottled water.

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