"Professor Smith is an Englishman, a world-renowned botanist with many identities. More recently, he is a senior member of the Royal Society for the Promotion of Natural Knowledge in London, and more recently, he is a visiting professor at many of the country's leading universities. Strictly speaking, he is currently in an employment relationship with Peking University and can leave at any time. Therefore, without sufficient evidence that he is the murderer, he cannot be arrested in a big way. So we need a good psychologist to pry his mouth open. “

"To be an expert is to be thoughtful. Okay, let's wait for him to come! Xiao Yong said.

"His situation is a bit complicated...... So we're going to ......," Pan Lei said.

After the matter was decided, Zhang Wei hurried to the forensic laboratory.

At seven o'clock in the evening, the operatives were already waiting at the entrance of the Public Security Bureau.

Soon, there was a sudden roar of a motor in the distance, and then everyone saw a red shadow, shuttling through the traffic, and whistling to the door of the Public Security Bureau, and then drifting and turning, and stopped steadily in front of everyone. Then, from the red Ferrari came a boy with a lollipop in his mouth and a high school uniform.

"Hello! Old Pan, we meet again. What's the matter, so urgent? I'm studying at night, teaching school more advanced math! ”

Suddenly, he noticed that there was something wrong with the atmosphere, and hurriedly stretched out his hand and said, "Ouch, this police officer is a newcomer!" Hello, I'm Boss Huang, an ordinary high school student, nice to meet you! ”

Pan Lei gave Xiao Yong a look. Xiao Yong hurriedly picked up the walkie-talkie and said: "Please send ten people from the traffic police brigade here, there are minors who violate the rules and drive over the speeding, that's right, the kind that is detained for 15 days!" ”

"Don't! I was wrong! No kidding!" Boss Huang hurriedly clasped his hands and said.

"Well, tell them to come later." Xiao Yong said again.

"Okay, you old Pan! Every time it gets worse than the other! It's true! Please please bring me out, I must have encountered something particularly tricky, quick! Let's talk about it, let Ye be happy! Boss Huang began to say with a hippie smile again.

Pan Lei gave Xiao Yong another look. Xiao Yong picked up the phone and said, "Hello? Is it Huang Youcheng's parents? This is the traffic police brigade, your son has just faced 15 days of detention for illegal driving, you have time to come and sign! ”

Boss Huang smiled evilly and said, "This police officer, you lied to me." ”

Pan Lei also smiled happily and said: "If you hang your son again, this will soon become a reality!" ”

Boss Huang immediately put away Wang Shi's disrespectful expression, and said in frustration: "Listen to you!" ”

"Said in the car! Now that we're here, let's go! Pan Lei said again.

In the car, Xiao Yong was still driving, and Zhang Wei was sitting in the co-pilot, still stuffy and not talking. Pan Lei briefed Boss Huang on the serial death case and the upcoming actions.

"If I were him, I would have been at large in England a long time ago." Boss Huang pouted and said.

However, he didn't. I've shown an acquaintance that he's still in the office. ”

"Office? Do what? Molesting schoolgirls? ”

"No, he's revising a student's doctoral dissertation. He was in our car...... Alas......" Pan Lei's expression was also a little unnatural.

"No, it's Zhang Wei, right? Oh my God, take the police to arrest your own teacher...... It's too prickly, no, it's too tragic, isn't it? Feeling Pan Lei's unkind gaze, Boss Huang quickly changed his words.

"But why didn't he speak?" Boss Huang asked.

Pan Lei did not answer, and Xiao Yong did not answer. When Boss Huang felt that the atmosphere was suddenly embarrassing, Zhang Wei on the co-pilot said slowly: "I am recombing the whole process of this case so far, 18 times. I always feel that it is too easy, and I always feel that the murderer is too easy to find, which does not fit my positioning......"

"Viagra, is this still easy? Without your involvement, this case would have been unsolved. Boss Huang said.

Pan Lei's mind also revisited the case and said: "From the investigation to the present, everything is normal." Without your extraordinary memories and observations, we would not be able to connect with plants. There will be no clues to the Face Mushroom and Professor Smith. Zhang Wei, I know you are very entangled in your heart. Isn't it still not entirely certain that the murderer is him? After all, the motive and the process of committing the crime are unknown, and we are just trying our luck in the past. ”

"Perhaps, I'm overthinking......"

"Actually, I also had a feeling that I was missing something...... Team Xiao, give me your phone. ”

Xiao Yong didn't hesitate, and handed over the phone: "Don't read the information randomly." ”

"Officer Xiao, from a psychological point of view, the more you say that, the more others want to see it-Lao Pan, you really log in to other people's QQ! Aha, why are there all beautiful avatars? It's over, did I find something great, will someone kill someone? ”

"Shut up! I'm assigning tasks, don't bother me, or I'll kill you first! Pan Lei said coldly.

"Cover!" Boss Huang hurriedly covered his mouth......

On the way back, Boss Huang wanted to speak several times, but found that the driving car, the silence, and the playing with the mobile phone, had to pretend to sleep, pretending that he was transparent......

Ten minutes later, everyone was in front of Professor Smith's office.

"Boom! Boom! Zhang Wei knocked on the door twice.

"Who?" A half-baked Mandarin voice came from the room.

"Teacher, it's me, Zhang Wei, let's see what needs to be improved in the graduation thesis."

"Okay, wait for me!" There was the sound of walking in the room, and then the door opened, revealing a raunchy, somewhat tired, bearded foreigner in his fifties.

After he saw Zhang Wei and his party, he was stunned for a moment, but he still greeted him generously.

Then, he hurriedly rummaged through everything, and finally found a little tea in a corner of the drawer, and began to boil water again, ready to make tea.

The others watched the whole time, and there was some silence for a while. Pan Lei noticed that on the desk, there was a photo with his back to them, and while Smith was boiling water, he quietly walked over, took a quick look, frowned slightly, and quietly took two steps back.

After finishing his work, Smith smiled and said, "It's been a long time since a guest came, and I'm still a little unaccustomed." ”

"Teacher, you, there is no need for this." Zhang Wei said.

"No, no, in China, a kind of tea is a magical thing in China, it can be a welcome guest, it can be a send-off, I have been in China for several years, I know it very well." Smith smiled again and said, "My protégé, can you introduce them?" ”

"They...... It's all my friends, let's take a look. Don't talk about this, teacher, my doctoral dissertation, is there a problem? ”

"Nope! Not at all, very exciting! Special data, perfect simply! It's just that there are places where English words aren't ...... enough," Smith's tired face became agitated.

"Authentic? Not like the grammar of foreigners? Boss Huang said tentatively.

"That's right! Just like me, I often get grammar mistakes, which is a trace of the mother tongue, and the subconscious expression is difficult to get all at once. ”

Boss Huang suddenly said faintly: "If I talk like you, my Chinese teacher will definitely beat me to death!" ”

"Killed? Why die? Isn't peace great? Professor Smith asked curiously.

Boss Huang, who has always loved gags, didn't know how to answer for a while.

Zhang Wei then said: "This time, I would like to ask you a question about botany. ”

"Excuse me?" Smith said with gusto.

Then, Zhang Wei took out the piece of paper from his pocket, spread it out, and said expressionlessly: "Fungal plants like this, teacher, have you ever seen them?" ”

After reading it, Professor Smith was stunned for a moment and said, "I've seen it, and I've used it...... Wait a minute! I know what you're here for! The day still came, I didn't expect it to be so soon...... But please wait a little longer, give me another half hour, I haven't finished your dissertation yet. ”

"But, why did you do that!" Zhang Wei's hand clutched the paper tightly, and his voice trembled a little because of his extreme restraint.

"After the correction is completed, send it over, and your doctoral dissertation can be passed, and the next step is to participate in the defense. Returning halfway now will cause you to lose all your work and spend a lot of time rewriting. ”

"Uhhh
