Panda Criminal Investigation Team

When there is only one piece of oil stain left in the plastic bag,

Yu Renjie finally gave up,

He slumped back to his seat.Cheng Bin threw the empty bag into the trash can at his feet,

He took another tissue to wipe his mouth,

Then he clicked his tongue: "It's really unpalatable."

Unexpectedly, Yu Renjie turned around and gave him a hard look,

Cheng Bin felt aggrieved inexplicably.He doesn't understand that the junk food he stuffed into his stomach is an internet celebrity omelette,

Very hard to buy.Hao Jinyang and Xiao Mi didn't know that when they went back at night,

Cheng Bin cooked three dishes and one soup to compensate Yu Renjie, and Yu Renjie left the egg cake behind after that.What they didn't even expect was that the set of university commemorative coins forced upon them by the school leaders that day,

One gold and one silver are real gold and real silver.

When they entered the police station the next day, Wang Haili hugged the commemorative coin gift box they threw on the table in various ways,

When you keep asking them to give you the gift box,

They just went to the Internet to check and found that the box of monuments is worth 880,

Made of pure gold and silver,

still limited edition,

A total of two hundred sets were released.

This gift box was instantly upgraded from broken copper and rotten iron to a hot potato,

before returning to school,

Hao Jinyang was restless looking at the golden and silver coins,

Even when he went to the bathroom, he had to check whether the drawer was locked, for fear that Wang Haili would steal things while he was not paying attention, or even make fake coins to exchange the bag.In his impression,

There seemed to be nothing he couldn't do.

And Wang Haili has been sitting in the office recently,

Because a colleague in the traffic police team was videotaped by citizens when he was accepting benefits, and it was posted on the Internet. When the turmoil was at the forefront, he chose to wash his hands in the golden basin temporarily to avoid the limelight.Without the benefits of investigating traffic violations on the road, he is desperately thinking of other ways to make money every day, and he has already gotten into the money hole.

Under Yu Renjie's urging, Hao Jinyang checked whether the drawer was locked twice, and went out with him.Yu Renjie took him and Xiao Mi to investigate the case together, and the destination was the hospital where Li Qianqian was, the No.1 People's Hospital.It was a coincidence that Cheng Bin was also going to that hospital, and there were a few victims of the Rush case inside, so the four of them drove in a car, talking and laughing all the way like an outing.

In the hospital lobby, Cheng Bin bid them farewell: "Gather here in an hour, call me if you have any problems." He hurriedly checked his watch and left in a hurry.

As soon as his back left, Xiao Mi began to speak ill of him: "The captain's calculations are really good, he has a big case where several people died, and people can be caught immediately, so he will keep it to himself. Cases where no one is dead are quite troublesome, so I will leave them to Yu Renjie."

Yu Renjie glanced at her, and he sighed together with her with a sense of sympathy.

The female internal medicine ward is on the third floor of the inpatient department. Li Qianqian lived in a double room. The nurse greeted another patient in advance.

This day, Li Qianqian's boyfriend Lin Hai was also there, and he was buried in his homework in front of the hospital bed. When Yu Renjie and the others entered the room, Lin Hai was pointing to a math problem in the exercise book and asked Li Qianqian: "Can you do this problem?" Until Yu Renjie revealed his identity, he still discussed with them: "Uncle Policeman, can you wait until I finish this question?"

Yu Renjie caught a glimpse of three apples and two bananas in a red plastic bag on the ground, and remembered Xiao Mi's previous hype describing how Li Qianqian's boyfriend ate soft food, so he believed most of it—the girlfriend who visited the hospital only brought Five fruits, and taking the opportunity to ask someone to help him with his homework, it's really unreasonable.But Lin Hai's subsequent behavior was quite impressive. He moved the stool back and silently peeled the apple.The flesh was round and smooth in his hands, and the apple skin was still attached to the ground without breaking. This technique is much better than Cheng Bin's.Yu Renjie withdrew his mind and focused his attention on Li Qianqian again: "Hello, classmate Qianqian, are you feeling better today?"

"It's much better." Li Qianqian said.

Li Qianqian is a white and fat girl. Because of her thinning hair, she wears a hat slantedly, with only a few strands of curled hair leaking from it.And her character seems to be as casual as the way she wears her hat, her body is leaning limply on the cushion, her toes are protruding from the quilt, and she is flexibly rubbing in broad daylight.If it weren't for her complexion is still relatively pale, people would think that she is not recuperating here, but skipping class on purpose.

"Don't listen to her nonsense, what's the matter!" Lin Hai took a small bowl, poured out the water in it, and cut the apples one by one with a fruit knife: "Her liver function indicators are not normal yet, The brain nerves were also damaged, I was already stupid enough, but now I am even more stupid, and today I have proteinuria..."

"Don't talk about such things!" Li Qianqian waved her arms to cover his mouth, but Lin Hai stuck an apple with a toothpick and brought it to her mouth, and she obediently opened her mouth and bit the apple down .Lin Hai, who is short and fat, and Li Qianqian, who is white and fat, when their faces get close, they can actually see some couples.

Yu Renjie asked Hao Jinyang to find two benches to come over. When he passed the middle of the ward, another patient's family member stood up and closed the curtain between the two beds with a swish.Yu Renjie had no choice but to touch his nose in embarrassment, and after sitting down, he said slowly: "Student Qianqian, don't feel pressured, try to recall what you ate before you got sick."

"Oh, okay." Li Qianqian propped herself up from the bed, and finally covered her toes under the quilt: "I ate in the cafeteria in the morning, lunch and evening, probably big ribs, or fried chicken legs, or fried dumplings? Anyway, I like to eat meat. Other things, I usually eat Lay’s Potato Chips, Shanghaojia Potato Chips, Pringles Potato Chips...and Lindt Chocolate, Ferrero Chocolate, Dove Chocolate...Crispers, Pocky Biscuits, Cute , Menglong, apples, bananas..."

She said the names of a long list of snacks and fruits, and Xiao Mi's mouth cracked when she heard it, and she turned to Yu Renjie and said, "Little girl eats more than you!"

Yu Renjie coughed, and looked at Li Qianqian: "Among the things you mentioned, are there any unbranded foods? For example, things from small workshops, or bought from small stalls."

"No, no, I bought them all from education supermarkets and online supermarkets. The authenticity is guaranteed. When I first started school, I had to prepare for a make-up exam, so I didn't have time to go shopping." Li Qianqian said.

"Please recall carefully, when you eat, who is around? Has anyone had the opportunity to add some ingredients to your food? For example, you left in the middle of the meal, or put the unpacked things at random. .”

"I really can't remember this. I usually eat in the cafeteria. Either with my boyfriend or with my classmates. I'm not sure if I went to the bathroom in between. For snacks, everyone shares them, so let's put them away." At the table, whoever wants to eat can take some. I eat theirs, and they eat mine. If there is something wrong, they should be recruited together. I don’t think there is a problem with the snacks.”

Her answer was as expected. It was not impossible, but it was too risky to poison a cafeteria where people were coming and going.It is not easy to poison fruit snacks and the like. Thallium salt is a white powder, and it is suspicious to sprinkle it directly on snacks. Not everyone can think of the powdered sugar biscuits in the previous case.To say that the most likely method of poisoning is to mix the colorless and odorless thallium salt solution into the liquid for people to drink.

The solubility of thallium salt in water is not high, so it is appropriate to put it into a large amount of water, or a solution where no obvious crystals can be seen even if it is incompletely dissolved.For example, colored drinks, such as the bucket on the water dispenser, as Xiao Mi and Hao Jinyang guessed yesterday.

So Yu Renjie took the trouble to confirm again and asked Li Qianqian if she had drunk any suspicious drinks, including pure water from the water dispenser.But Li Qianqian said that this is impossible.

"Drinks are bought in the supermarket, and the water is also from the water dispenser in the school. Everyone is drinking it. It must be no problem. You ask about my water cup. I carry my cup with me. I put it in the dormitory at most at night, but it must be It has nothing to do with my roommates, the dormitory is the safest place."

When Li Qianqian said this, Lin Hai slammed the bowl of apples on the table: "Your brain must have been poisoned, I think it was they who poisoned you!"

Hao Jinyang was most willing to hear this, and he immediately regained his spirits: "Why do you say that?"

Lin Hai said that the three girls in Li Qianqian's dormitory were all vitriolic masters. Li Qianqian was sick and had sleep disorders, and she couldn't sleep well.

"Gossip has spread to the boys. They say that Qianqian has a mental problem, that she is ugly and not honest, that I fell in love with her blindly, that we are a turtle with a bastard, and leftovers with leftovers. Sooner or later, we have to break up with her, because as long as I sleep in a bed, even Wu Dalang like me won't want her!"

Lin Hai clenched his fists, intending to gnash his teeth, but Li Qianqian was just like a normal person, just giggling there.

"Oh, it's all nonsense. It's just a rumor. If it's passed around, it will deteriorate. Even if they have an opinion on me, they won't say that about me." Li Qianqian pointed to a novel on the cabinet and said: "They You came to see me two days ago and brought me tutorial books and novels!"

Li Qianqian stretched out her arms to fetch the novel. The cover of this novel is pink, with exquisite comic patterns drawn on it: "This is written by my favorite author. They all remember it. I wanted to wait for it." I read it again after the exam, but I still couldn’t help it, I’ve read it a little bit.”

There are indeed obvious traces of flipping through the book. The first third of the pages are wrinkled, while the last two thirds are very flat and brand new.

After showing the novel, Li Qianqian asked Lin Hai to open the low cabinet next to the bed for her. Inside were a few books and a few copies of printing paper: "They helped me bring the books for the compulsory courses, and copied the notes for me. This is the exercise booklet I will use for this make-up exam. The books in the library are due and have been borrowed out, so they specially printed a copy for me and sent it here. I am so touched! In order to repay They, I must do the questions well this afternoon and stop reading novels. The teachers in the department said that it doesn’t matter if I miss the make-up exam. When I go back to school, they will arrange a make-up exam for me alone. I must pass it! "

She threw the novel into the cabinet, and put the copy of the exercise book on the cabinet instead, so as to supervise her study.Then Yu Renjie asked a few new questions, but Li Qianqian still stayed on the previous question, obsessed with explaining how harmonious her relationship with her roommate was, and had to interject a few sentences from time to time.

"I always snore when I sleep. They did express their dissatisfaction to me. The worst time they went to the department and asked me to move the dormitory, but other times they just talked casually, and the tone was not serious at all. Even that time We went to the department to discuss the issue of moving the dormitory, and they just wanted me to move out at night, and they still want to be with me. That is to say, we have classes and meals together, but we don’t sleep together at night. I asked them, yes I don’t have any dissatisfaction, they said, there is no dissatisfaction, the only contradiction is sleeping. Leaving aside the issue of sleeping, our relationship is really good. And I haven’t moved out now, we are very happy to live together of."

"We like Oppa similarly. We often have snacks together at night and watch Korean dramas together. All the Song Joong Ki and Lee Myung Ho in my computer are copied to me by them!"

Lin Hai wanted to refute her from time to time, and she said, "Remember last year when the school accidentally raised the alarm? The earthquake alarm sounded in the middle of the night. Everyone thought it was an earthquake. Everyone in your boys' dormitory ran for their own lives. There was no one there. Take care of you! Our dormitory is fine, Yang Ying woke me up, He Jing helped me put on the shoes, and Wang Xiaoqi dragged me all the way to run. Although it was a false alarm, if it was true, without them, I must be dead."

"And the last time I peeled an apple and cut my hand, I bled a lot. It was the three of them who accompanied me to the emergency room, comforted me, and registered for me. They didn't come back until midnight. Later They help me wash my socks, and each of them washes them for a day. You won't understand the friendship between us girls."

"And, and..."

Even Yu Renjie felt annoyed after hearing it, and quickly concluded for her: "You think your three roommates must be innocent, your boyfriend will never poison, and Zhou Yan from class three is absolutely innocent, yes It's not like this?"

Li Qianqian nodded: "Yes, none of them will harm me."

"When the police investigate the case, one way of thinking is to look at the motive of the crime. Who will harm someone for no reason, right? Do you think there is anyone around you who will poison you?"

Li Qianqian thought for a while, and finally replied, "No."

After hearing this, Xiao Mi wanted to roll up her sleeves and shake her awake. If no one poisoned her, where did the poison come from? Could it have jumped out of the ground? Yu Renjie said slowly: "I believe you must have thought about yourself." How did you get poisoned, I really want to hear your thoughts, would you like to share it?"

Confusion appeared on Li Qianqian's face, and she nodded immediately: "Don't laugh at me for what I said."

"I will not laugh at you." Yu Renjie assured her.

"It's like this. I thought about it for a long time, and I think there are two possibilities." Li Qianqian said: "The first one is that I went to Thailand with my friends during the summer vacation. We took a speedboat to a small island. I don't know the name, and I probably don't have a name. We saw no one around, so we jumped into the sea and swam for a while. At that time, I was accidentally bitten by a fish in the water, and a piece of skin was broken. My arm was swollen for several days. I was wondering if this fish is poisonous. The metal content in its body exceeds the standard. When it bit me, it brought the toxin to me. When I was bitten, it happened to be when school was about to start, and the incubation period was more than ten If it is one day, I will start to have seizures when I go to school, and the time is about the same."

"Probably not," Yu Renjie said with a stiff mouth, "If that's the case, that fish would have been poisoned to death long ago, and the one that bit you is a zombie fish, and I've never heard of thallium poisoning having an incubation period."
