Panda Criminal Investigation Team

Yu Renjie brought Cheng Bin to the end of the team,

It turned out that he wanted to buy cakes a long time ago,

On the screen of the mobile phone is the introduction page of X Big Egg Filled Pie.Cheng Bin hopes that the team will be longer,

longer,

To calm his racing heart,

But when he caught a glimpse of Yu Renjie's handsome profile,

I wish the line was shorter,

Make it shorter, so that he can find a quiet place where no one is around, and continue the unfinished conversation just now.

"Well,

I counted on you to add bacon and cheese to you. "Yu Renjie handed a hot pancake to Cheng Bin's hand, the pancake was wrapped with a layer of white paper,

already soaked in oil,

It becomes transparent, and the burnt aroma of the eggs is mixed with the sweetness of the sauce,

Cheng Bin's glasses instantly fogged up.At this time, Yu Renjie was holding his egg-filled biscuit and kept blowing,

Blowing and sniffing: "Let's go."

The two made room for each other,

The students behind are moving forward,

Stretch your neck to see the ingredients on the signboard,

With a burst of fragrance,

With the sound of the iron plate creaking, it is a feast of color, fragrance and taste.

Freshly baked egg-filled biscuits are crispy on the outside and tender on the inside, much more delicious than the cold ones,

The two found a bench in the shade,

Hastily settled their supper.

"I think Yang Ying was probably the one who poisoned him, what do you think?" Cheng Bin puffed out his cheeks and kept exhaling white air from his mouth.

"I think so too." Compared with Cheng Bin, Yu Renjie's eating looks much better. When Cheng Bin was about to finish eating, he took a third bite: "The problem now is how to find evidence. The school reported the crime late. In two days, the evidence may have been disposed of."

"It's not too late. Li Qianqian went to the hospital on Saturday and found thallium poisoning on Sunday. Today is only Friday. If a classmate in the dormitory poisoned, it may not be too late to destroy the evidence. From the discovery of the poisoning to the present, there is no evidence. One weekend apart."

"It's true. Their class schedule is very full. There are public classes and project discussions at night. They don't have time to travel far. Even if they throw away the evidence, they won't be able to throw it very far." Yu Renjie blew on the cake in his hand and said: "Li Qianqian is chronically poisoned. If the prisoner injects a little poison every day, let me put it in a more civilized way. The iron pestle grinds the needle, and dripping water wears away the stone... The symptoms will come up slowly. If I were a prisoner, before she became serious, it would be I won’t throw away the poison|drug, so I have to continue to download it, so...it’s possible..." Yu Renjie lowered his head and took a bite of the pancake, and accidentally brought out a whole piece of tenderloin, he was taken aback for a moment, He lowered his head and sucked the piece of meat into his mouth together: "The poisoned utensils and poison | medicine really haven't had time to deal with it yet."

"I don't know if the pickle boy can find out what he brought back. Although I think it's useless, but now, I'm starting to take chances." Cheng Bin had already finished eating the cake, and he crumpled the plastic bag into a ball. With the hand in his hand, he turned his head to look in Yu Renjie's direction. When Yu Renjie saw it, he immediately turned his face to the side and speeded up his swallowing.

"Don't worry, I won't snatch you." Cheng Bin stood up: "Eat slowly, I'll be right back."

Two minutes later, Yu Renjie was thirsty after eating the biscuits, and Cheng Bin happened to hand him a bottle of water: "Now education supermarkets can use online payment."

Yu Renjie said thank you, leaning back to back with Cheng Bin, each opened their mineral water and drank gulp.After Yu Renjie put the cap on the bottle of mineral water, he raised his head and found that Cheng Bin had turned around and was looking at him intently. His eyes were deep and twinkling, as if the ocean of stars was reflected in the dark night.At this time, Cheng Bin suddenly reached out and pressed his shoulder with great force.

"Yu Renjie, I have a question for you." Cheng Bin said with trembling voice: "Please answer honestly, this question is very important to me."

Yu Renjie looked at him blankly and said hello.

"If I said...if I said...that day...I want to know..." Cheng Bin's eyes flickered fiercely, he opened his mouth, but he seemed to be dumb and couldn't make a sound, only his Adam's apple was still moving up and down.Yu Renjie felt that the strength on his shoulders suddenly increased, he grabbed himself almost with all his strength, then Cheng Bin frowned, and when he opened his mouth, he said in a very loud voice: "I want to know why you like to eat so much! "

Yu Renjie opened his eyes and mouth wide, and said after a while: "This is a philosophical question."

On the way to the parking lot, Yu Renjie muttered to Cheng Bin: "You ask this question because you think I eat a lot, but you don't really know how to eat, do you? I really don't know much about food. Is the food new or not? Whether it’s delicious or not, I can’t even taste it. I’ll eat anything that fits into my mouth. For example, the few dishes you cook, right, I can still eat quite a lot.”

At this time, a fallen leaf fell and landed on his hair. Cheng Bin was stunned, and reached out to help him remove it.

"Oh, thank you." Yu Renjie looked up at the canopy of the big tree above his head and said, "I think that I like to eat because of human curiosity. Didn't we do a psychological test of the Big Five personality?" , one of which is aimed at people's curiosity, and my score in this piece is two full points higher than the average! In other words, I have a lot of curiosity about food and a spirit of continuous improvement and exploration."

"Curiosity? Exploration?" Cheng Bin tossed the leaf casually, and the wind blew it further away.

"When you see food, don't you want to know what it tastes like? If you want to know the taste, don't you have to taste it?"

"But I see that you eat exactly the same things, such as the blue bag of potato chips you eat every day, and the sandwich rolls in your cabinet, which have never been broken."

"You don't understand this. The process of enjoying food is too short for human beings to remember its taste. The so-called life and learning, people must always be curious about food. You can't step on it twice with people. You cannot eat the same food twice, just as you enter the same river."

Cheng Bin stopped and clenched his fists.He choked up his words and wanted to speak, but in the end he lost to timidity and Yu Renjie's curious theory, and now he can't bring it back.So he was so uncomfortable that he couldn't help but want to retaliate.

"The words are so sweet, but in my opinion you are just greedy. You look like you are lazy and talk nonsense all day long! I have never seen someone as greedy as you in my life. You fart and pop out a bean. You have to wash it and put it in your mouth to eat!"

Yu Renjie turned his head, squinted his eyes, gritted his teeth, and glared at him fiercely again after only a short day.

In the afternoon of the next day, the test results of the forensics department came out. No usable fingerprints were collected on the reagent bottles in the laboratory, and the students all wore gloves to handle poisonous substances.However, no thallium element was detected in all the items that Hao Jinyang and Xiao Mi carried back, including the thermos cup and bowls and chopsticks that Yu Renjie brought back from the hospital the next day.Later, they went to X University again to search for clues, but they did not find any objects containing thallium.These items have either been cleaned up, or they are not carriers of poison at all.

But Li Qianqian should be able to detect a small amount of toxic ingredients in Li Qianqian's commonly used items. Even if it is not a container that directly contains poison, items that directly contact the mouth, such as toothbrushes and tea cups, are likely to be stained with a small amount of toxins.Now I can't find it at all, but it seems abnormal.

Xiao Mi retrieved the purchase records of thallium and thallium salts from the government agencies for the past three years. Among the 23 qualified enterprises in the city, 19 had purchased thallium products during this period, and none of them except X University. Find any businesses with a direct connection to people around 李千千.It is almost certain that the thallium in Li Qianqian's body came from the chemical laboratory of X University—someone stole some thallium sulfate reagent from it, and dropped it into Li Qianqian's food bit by bit.

If it weren't for the sensation of the Zhu Ling case that indirectly popularized the knowledge of thallium poisoning, and the hospital had a stock of anti-drugs, I am afraid that no one would associate her symptoms with poisoning, and it would be impossible to get rid of the thallium in her body in time. Even if she doesn't die by then, I'm afraid she will become a useless person-what a vicious murder plan.

But as Xiao Mi said, all the things that could be poisoned have been recovered by the police. Li Qianqian also denied eating any suspicious food. In addition, the hospital also confirmed that there was no problem with her diet on the day when her illness relapsed. To the point where anyone else has entered that ward... Will this case be shelved due to lack of evidence like the case of Zhu Ling?

When the evidence was excluded one by one, the case became more and more bizarre, like a thick fog blocking the truth.Who was the poisoner?And how did Li Qianqian get poisoned without anyone noticing it?

Two days later, Yu Renjie took Hao Jinyang to visit Li Qianqian again.Before going out, Yu Renjie deliberately took out two joke books from the bookshelf, and prepared to give them to her to relieve boredom.Hao Jinyang looked at the two almost brand-new books, and asked him why he didn't bring the Laughing Dead You Pay Your Life series, since they are old anyway, and there are seven books, so if you give away two books, there will be five more.It was almost the first time that Yu Renjie put on a straight face with him. He said seriously that this series is his favorite, and it is out of print. No amount of money can buy it. He also asked Hao Jinyang to be careful when watching it. Don't read while eating snacks, it is easy to stain the book.

It was only then that Hao Jinyang realized that although these books were old, they were well preserved, and the writing was neat and flat, without even a single corner.Yu Renjie, who is so scruffy, can have such neat books, almost comparable to the top ten wonders of the world.But what kind of treasure is this kind of book without connotation, it is as precious as the hardcover version of the world's classics, it is really sick, Hao Jinyang secretly thought in his heart.

When I went to see Li Qianqian this time, her little boyfriend Lin Hai was not there, and Li Qianqian was lying in bed playing with her mobile phone. On the bedside cabinet was the pink cover novel I had seen last time and a half-eaten box of Fei Lie chocolate.After a few days, her complexion is still not good, with a layer of grayish-yellow color. The novel has already been read, the paper of the whole book is bent, and the cover has been slightly raised, which reminds Yu Renjie of the chemical experiment of X University The weighing record book in the room.

"I wanted to review at first, but I couldn't get in the review. Lin Hai was right. I really thought I had become stupid and couldn't remember anything." Li Qianqian pointed to her head and said with a smile: "But anyway, I was the last one in the class. Yes, it can’t be seen from the rankings, at most it will be surpassed by Lin Hai. The doctor said that if there is no problem in a few days, I will be discharged from the hospital.”

Her forced smile made Hao Jinyang feel very uncomfortable. He snatched the joke book from Yu Renjie's hand and handed it to her with both hands: "Don't read it if you don't like it. Now is the time to rest! If you are bored, look at this Two books, we brought you specially, this is, um..." He looked down at the cover of the book, and read: ""The Greatest Joke King in History", and this one is..."The King of Humorous Jokes for Primary School Students" ..."

Li Qianqian took the book with the same embarrassment as Hao Jinyang. She put the two joke books on the cabinet, stacked them on the girl's novel, and said thank you with a stiff mouth.

Hao Jinyang blushed, and wanted to explain that these two books were not chosen by him, but his brother’s collection. When he turned around, he saw Yu Renjie staring intently at the two unpopular joke books, refusing to look away for a long time. If you move away, it's like being in a trance.Hao Jinyang coughed, tugged at the hem of his clothes, and whispered in his ear: "Brother, I've sent everything away, it's not good to come back again."

But Yu Renjie shook his head, shook Hao Jinyang's arm silently, and rushed to Li Qianqian's bed instead: "Can you show me your book?"

"Senior brother, this is too embarrassing!" Hao Jinyang chased after him with a red face: "It's just two joke books, if you give them away, I will give them away, and I will buy them for you when I go back!"

Yu Renjie turned his head and looked at him with disgust. After that, he forgot to push the two joke books he brought, and picked up Li Qianqian's novel for girls, flipping through it carefully. To the pages of the book, from the spine to the bookmark... When he was done, he opened the door of the bedside cabinet, talking to himself, and moved all the textbooks and photocopies inside to the hospital bed, filling up the sheets.

In Li Qianqian's astonished eyes, he checked one by one, confirmed, and finally raised his head: "Student Li, can I see your hand?"

Li Qianqian nodded blankly, and handed out her left hand with the hanging needle: "I'm too fat, and the blood vessels are also thin. Today, the nurse poked the blood vessels several times before they got into the blood vessels, and they were all swollen."

But Yu Renjie was not interested in her swollen left hand, but directly grabbed her right hand and pulled it in front of him. The back of Li Qianqian's hand was bulging, her palm was cold and wet, and the pad of her right index finger was a little white.

Yu Renjie took out his mobile phone and took a photo of her fingers. When he spoke again, his voice was full of excitement: "When you read and turn pages, do you have the habit of licking your fingers?"

Li Qianqian was taken aback for a moment, then nodded.
