"What bird?" Ling Ling asked.

"There is a mythical beast recorded in the Dunhuang Ben Bai Ze Spirit Map, named Birch. If a person has a nightmare at night, when he gets up in the morning, he simply faces the northeast and recites the incantation: 'Birch Birch, do not drink or eat, eat and eat happily, and his nightmare will be Birch, and he will be tired of the dream and be happy.' Then it will be fine. ”

Ling Ling listened and said first: "Why are you here again, I don't think you want to teach in the university, why don't you go out and set up a stall to tell fortunes." ”

"I'll consider your suggestion." Liu Mengwei said seriously, and then said to Gao Caiqin very seriously: "Okay, let's start quickly." ”

Gao Caiqin also looked embarrassed, obviously not believing: "Are you serious?" ”

"Seriously, of course!"

"This ...... Will it really be useful? Gao Caiqin will be skeptical.

Ling Ling snorted coldly: "It's strange if it's useful." ”

"How do you know? Didn't you try? Liu Mengwei stared at her, and it seemed that she was also serious.

"I don't have to try, I don't know it's impossible!"

"If you don't try what you think is impossible, if everyone is you, society will have stagnated."

Ling Ling was dumbfounded by her: "Whatever you want!" ”

Liu Mengwei changed her face, and said to Gao Caiqin with a smile: "Let's start, tell me the effect after trying it." Maybe I'll be able to write a paper based on this, and I'll add you to my credits list when the time comes! ”

Seeing that she was so persistent, Gao Caiqin was embarrassed to refuse. They found a corner where no one was, after all, it would be too shameful for others to see it.

"Birch Birch, who does not drink and eat, often eats happily, and whose nightmares are attributed to Birch, who is tired of dreams, and who is blessed." Gao Caiqin stammered three times, and finally memorized the string of words. Then it was much smoother, and I read it three times quickly.

"Birch! Birch! "There was a burst of birdsong in my ears, sometimes graceful like a warbler, sometimes as noisy as a crow.

"Don't drink alcohol and eat food, eat often and happily." A small bird with brown feathers and a long tail, which landed on a tree beside them, had a smooth body, black stripes in its eyes, and a curved beak with a hook.

"His nightmare belongs to Birch, and he is tired of his dreams, and he is happy." Gao Caiqin finally finished reading the last time, and also noticed this little guy who was chattering.

Liu Mengwei looked excited, but lowered her voice, for fear of scaring the little guy away: "You really called Birch!" ”

"You say...... The bird? Gao Caiqin was also a little confused.

"The bird's name is Shrike. Legend has it that during the reign of King Xuan of Zhou, there was a virtuous minister named Yin Jifu, who listened to the slander of his stepfamily and accidentally killed Birch, the child left by his ex-wife. One day he saw a bird in the suburbs, and stopped on a mulberry tree and chirped to him in a sad and sad voice, and he suddenly felt that this bird was the soul of his son Birch. So he said, "Birch? It's my son, and it's my son. If it's not my son, don't fly away. The bird flew over and stopped in his carriage. This is where the name of the little bird in the shrike comes from. ”

"Little witch, your spell has worked." Liu Meng winked at her slyly.

……

After sending Gao Caiqin away, Wen Qiao finally asked, "Is it really necessary to do this?" You directly tell her that the first time you saw Lin Xuerou was real, and the second time you saw it was fake. ”

"So, you already know?"

"Lin Xuerou had an epileptic seizure just now and has been sent to the hospital for first aid."

"So?" Liu Mengwei still didn't seem to understand what he meant.

"Gao Caiqin gave her aminophen Mamei tablets, and the chlorpheniramine contained in them may induce epilepsy." Wen Qiao said. "So, I suspect that Lin Xuerou has taken Gao Caiqin's medicine at least once."

Liu Mengwei nodded slightly, but did not speak. He couldn't see through this woman, but he unconsciously gave birth to a trace of unconfidence in his heart: "Isn't that so?" ”

Liu Meng's eyes flashed: "Maybe." ”

Wen Qiao had a stomach full of questions he wanted to ask her - the six-pointed star pendant left by Feng Cheng, the secret left by Gao Liqun on his children, the mysterious man who pretended to be a courier, and Song Yuanxi who left only one name. But he also knew that the time had not come, and even if he put the knife on her neck, he might not be able to ask anything useful.

He's a patient guy, but he's not the kind of guy who just waits and never takes the initiative.

"Recently, we encountered two cases, and after checking around, we don't have a clue, how about asking Professor Liu to do a criminal profile?" Wen Qiao threw out his offensive move and waited quietly for her to take it.

Liu Mengwei's eyes narrowed slightly, and she was slightly surprised by his request, but she still agreed: "You might as well talk about it." ”

Although Ling Ling was a little reluctant, after all, the director had spoken, and she had to briefly tell her about the case of Lin Hui and Lu Yifan.

Liu Mengwei listened carefully to Ling Ling's narration, and was silent for a long time.

"How? Okay? Ling Ling didn't really believe in crime profiles, and her attitude was the same as that of Ling Feng. No matter how accurate the profiling is, the final verdict still depends on evidence, but since the evidence can be found, what do you want to do with this ethereal profiling?

"Then ask the two police officers to show me the scene of the crime first."

The three of them came to the school gate. Liu Mengwei pulled Ling Ling to ask every detail of the day of the crime, the victim's path, eyewitness testimony, forensic examination, investigation and visit, waiting, Wen Qiao stood aside to add some things she didn't say, and by the way, she went through the context of the case again.

"So, that internet celebrity has been here too?" Liu Mengwei looked at a video screenshot on Ling Ling's mobile phone, and it was the live broadcast that Lu Yifan was standing at the school gate.

"Yes. Later, it became more and more noisy, and Lu Yifan, who was the first to broadcast this matter, was also pushed to the forefront. Then he wanted to use this opportunity to build momentum for himself to become famous. On the surface, he wants to apologize for the public opinion disputes he caused, but in fact, he is still fooling the public and attracting attention. Ling Ling's tone was full of disdain, and after she watched the live broadcast that day, she really couldn't have more sympathy for Lu Yifan.

Having said so much, Ling Ling wanted to ask Liu Mengwei again, wanting to know what she was thinking now. But a man not far away caught their attention, the man was of medium to high stature, wore a pair of glasses, a round face and round eyes, and wore an off-white trench coat and black trousers, and he looked very polite.

Seeing that several of them were looking towards him, the man also took a few steps forward, but his eyes stayed on Wen Qiao's face.

"Are you...... Wen Qiao! ”

Wen Qiao's face didn't change much, and he couldn't guess what he was thinking, so he slowly spit out two words after a long time: "It's me." ”

The man saw that he reacted for a long time, but he didn't recognize himself, and hurriedly said, "You don't know me anymore?" I'm Peng Ruirui, and we were table mates for a while in high school! ”

Wen Qiao finally pulled out a smile: "As soon as you say this, I remember, I remember the name, but it's a little wrong." ”

Peng Ruirui also smiled embarrassedly: "Oops, that's it!" I gained a lot of weight after going to work, and I can't compare it to when I went to school! Your figure hasn't changed much, and you're still as handsome as ever. The last time you came to our school, I saw that you were a little familiar, and when I saw you today, I finally remembered it. Alas, I remember you went to medical university, why are you a police officer now? You're not going to be a medical examiner, are you? ”

Wen Qiao's smile was a little meaningful: "Yes, you have a good memory." ”

Peng Ruirui smiled, and finally found an opportunity to speak to the two ladies beside him: "I didn't expect that there are such beautiful beautiful policemen in our city. ”

He stretched out his right hand, but not towards Ling Ling, but towards Liu Mengwei.

Liu Mengwei didn't refuse, and gave him a polite smile: "Hello." ”

Ling Ling was a little dissatisfied: "Is there any mistake, I am the ......"

"Mr. Peng is a teacher at this school?" Liu Mengwei didn't give her a chance to speak, and asked Peng Ruirui directly.

"Yes, I'm teaching physics in two classes in junior high school right now." Peng Ruirui

"Physics? A discipline that can explain the operating principles of all things in the world, from the planetary universe to the microscopic particles, the basic motion forms and laws of all matter are its research scope. What an amazing subject! Liu Meng praised slightly, saying that Peng Ruirui's ears were about to turn red.

"I'm just an ordinary middle school teacher, standing on the shoulders of giants, and telling these children the physical theories summarized by the genius scientists of the past through natural phenomena."

"That's a great thing, too! The leader is an important role. Einstein's famous formula of relativity E=mc2, such a short concise and beautiful character supports the tall buildings of modern physics, which is breathtaking. Perhaps, a good teacher's guidance and a single stroke can inspire others for a lifetime. ”

"Oops......" Peng Ruirui looked at her blankly, her face already red.

Seeing that the two were chatting hotly, and he and Wen Qiao seemed to have become decorations, Ling Ling really couldn't stand it, and decided to find some sense of existence: "I also know this, that is, the great physicist who said that 'God can't roll dice'!" ”

Peng Ruirui came back to her senses and nodded to her: "Yes." The police are so knowledgeable that they know everything. ”

Ling Ling listened to his compliment, and finally relieved her heart, but after all, she had just left the school not long ago, and she was easy to get carried away when she was proud: "However, why doesn't God roll the dice?" ”

Peng Ruirui was stunned for a while, and Ling Ling suddenly realized that when he asked like this, he was completely timid, and he was embarrassed all of a sudden.

Seeing that the atmosphere suddenly cooled down, Peng Ruirui coughed lightly, decided to break the embarrassment, and explained: "Although Einstein's equation of relativity is a great genesis invention, it does not encompass all the laws of physics. Just as Newtonian mechanics cannot be established in the microscopic world, he proposed the law of universal gravitation to supplement it, but if the speed of an object is close to the speed of light, then Newton's law of universal gravitation will be insufficient. Therefore, Einstein proposed the special theory of relativity to modify Newtonian mechanics. Later, he discovered something that the special theory of relativity could not explain, so he proposed the general theory of relativity to further revise it. ”

"Physicists have never been able to find a unified law that can cover everything, so at this stage they can only be tinkers who check and fill in the gaps. In this way, there will inevitably be fish that slip through the net, and there will be fish that slip through the net, which means that there is an unknown, unpredictable, and unpredictable part of our world, that is, uncertainty. Perhaps the greater the scientists, the more they want to try their best to get to the bottom of all the secrets of the universe, and they are not willing to accept a 'uncertain' result after they have spent their whole lives in the end. ”

"Therefore, Einstein said that 'God does not roll dice' because he firmly believed that there is a unified law in the universe that can describe the objective physical world, and the uncertainty and unpredictability in quantum mechanics are only because people's understanding is not complete and deep enough."

Ling Ling didn't seem to understand when she heard it, but she didn't dare to speak anymore, and scolded herself in her heart for why she had nothing to do just now, and asked like that.

Peng Ruirui's tirade made her feel like she had returned to the sleepy afternoon on the middle school campus, listening to the teacher's words on it one by one, while the heads of the students below were already a mess of mush.

Physics, mathematics, those complicated formulas, abstract and obscure concepts, dazzling auxiliary lines are a nightmare for many students!
