Seeing that no one answered, Zhang Wei's face rose slightly and said: "I have made many assumptions, such as weather, ultraviolet rays, air humidity, rainfall, and the activity rules of some mosquitoes and flies, but I have ruled them all out, and finally I boldly hypothesized one, that is, the growth law of plants!" And it's the same plant, most likely a new variety of fungus, which explains why they are all the cause of fungal poisoning. ”

Everyone else nodded.

Xiao Yong, who didn't know when he came back (Zhang Wei showed a contemptuous gaze online), said: "This must have been deliberately created and put on purpose." ”

"If this is the case, then this man must have a deep knowledge and study of botany." Pan Lei said.

"Expert Pan, I have a few directions of investigation, can you say that?" Xiao Yong said.

"Of course, it's your territory." Pan Lei shrugged and said.

"Good. First of all, a group of people contacted the local police in the jurisdiction of these deaths and assisted in taking photos of all the plants around their houses, especially fungi, and none of them could be spared! I hope to see all the photos by 6pm! ”

"Yes!" The three of them took the order.

"The second group, to check whether there are any reports on the discovery of new fungal plants in newspapers, periodicals and magazines at home and abroad in the past three years, I also hope that the results will be available at six o'clock."

"Yes!" The three policemen said bitterly, and then they threw themselves on the computer to check the information.

"Is there anything to add to Expert Pan?"

"Then I'm not welcome, I was just inspired by Zhang Wei, and finally this female policeman went to contact and implement one thing: whether these peachy news came from the same person, or the same group of people. If not, when I didn't ask, if yes, ask two questions: What is the purpose? Who made them write? Pan Lei said.

"Good! I remember the question, but who am I going to ask? The female policeman asked puzzled.

"Lead the snake out of the hole, you know?" Pan Lei said tentatively.

"Huh? I know what it means to lure the enemy into action. And then what? ”

Zhang Wei looked at Pan Lei and said expressionlessly: "She reminds me of a person...... This female police comrade, have you heard of fishing law enforcement? ”

"Fishing enforcement? Of course, we haven't done it...... Wait a minute! I understand......" The policewoman ran to her desk with a flushed face, turned on the computer, and began to operate.

"What about us?" Xiao Yong asked again.

"Practice is the only criterion for testing the truth, and there are victims here in Beijing, so if we go there, we may find something else."

"Okay, I happened to have been there too, I'll drive and take you there."

Pan Lei pulled out the file of the deceased man in Beijing by the way.

But in the car, it was Zhang Wei who studied the archives.

"Did you find anything special?" After Zhang Wei finished reading it, Pan Lei put down his phone and asked.

"Yes! I found that Uncle Pan, you are getting worse and worse. Your position is to overcome all difficulties, use your wisdom, ability, and life to find out the real culprit, restore the truth, and eliminate evil. Now I asked my partner to find out the real murderer, you are playing with your mobile phone, and at the end you asked me if I found it, is this appropriate? Zhang Wei said unceremoniously.

"Huh? Aren't you more handy at this? Didn't a PhD in botany just come down last month? You don't want to take the opportunity to practice? I'm good at dealing with people, not plants. Moreover, I am the easiest to solve the case with you, and I am nervous to death with other people! ”

"Really?"

"Of course! I wasn't just playing with my phone. I searched for other information about our target and found a secret. ”

"What's the secret?"

"Let's start with your findings."

"This person's name is Gu Chaoping, and in the spring of this year, he was hospitalized for pollen allergies, but I don't know if there is a key between this pollen and the fungus. Well, it's your turn. ”

"What I found out is that Gu Chaoping's last girlfriend was a student of your idol, Mr. Smith, when he was teaching in China, and she was also his crush."

Xiao Yong suddenly said leisurely: "Many Chinese girls have been snatched away by foreigners, and the pressure on young Chinese men is great." ”

"Teacher-student love? No, teacher lover? There must be something extraordinary about this woman being Smith's crush, where is she now? ”

"Beijing Psychiatric Hospital ......," Pan Lei said leisurely.

"Huh? Why? I'll take a look at it when it's over. Captain Shaw, do you know where this psychiatric hospital is? Zhang Wei was slightly surprised.

"I know, it's not far from Gu Chaoping's home."

It took two hours for them to reach their destination. Because the previous hour and a half was spent in congestion......

There are already two policemen, an old man and a young man, waiting at the scene.

"It's hard work, I've kept you waiting." Xiao Yong stretched out his hand as he spoke.

After the two policemen Xiao Yong shook hands routinely, they excitedly shook one of Pan Lei's hands.

"Expert Pan! I have admired the daimyo for a long time! I finally saw it alive today! The young policeman said.

The elderly policeman glanced at him, and said excitedly: "The words are inappropriate, it should be said that I saw a living body...... No, it's in person! I'm sorry, I'm a little excited. ”

Then they saw Zhang Wei with a bag on his back, and the young policeman couldn't help but be curious: "Expert Pan, who is this?" ”

After Pan Lei briefly introduced Zhang Wei to others, he waved his hand helplessly and said, "Feel free, we're going to start working." ”

The floor where Gu Chaoping is located is still relatively high-end, although it is not a detached house, but it only lives on three floors. He dwelt at the top.

The flower bed in front of the building was carefully repaired, and Pan Lei and Zhang Lei looked for more than ten minutes, but they didn't see a single weed.

When he was about to go to the building, Zhang Wei took out a small empty bottle from his backpack, then opened the cap and shook it around before closing the lid again.

"What is this going to do?" The young policeman asked curiously.

Zhang Wei labeled the bottle and replied casually: "Of course, it is air substance testing." Now, let's go inside. ”

Next, Zhang Wei collected air at the door of the floor, the stairs, the door of Gu Chaoping's house, and different places in the house, and put it in different categories.

The rest of the room is unusual, and there are no signs of plant growth.

Only on the floor of the bedroom, a strange humanoid pose was drawn with white lines - only legs and half of the body and a small bulge.

"Can you describe the state of the deceased?" Pan Lei asked strangely.

"I can't tell, this is a photo, please take a look." The elderly policeman took out the photo from his bag and handed it to Pan Lei.

Zhang Wei also came over to watch.

Gu Chaoping in the photo, naked, kneeling on the ground. The bulge was the index finger of his right hand, pointing in one direction.

Pan Lei and Zhang Wei looked forward along the bulge and only saw the wall.

Zhang Wei frowned, and suddenly knelt on the ground, as if taking care of Chaoping's death posture, then stretched out his fingers and slowly stood up.

Or the walls.

"No, he died of shock at the time, and it should have been very painful when he died. If you look at his right foot facing outward, it shows that he is indeed deflected to the right, as for how much ...... has deviated"

"27 degrees." Zhang Wei accurately reported the number, then shifted his right hand to the left, and two seconds later, his finger pointed to the window.

The curtains had been drawn, and Xiao Yong was standing closest to the window, so he unveiled the scene.

Just when everyone was looking forward to seeing what was outside the window together, they only saw Xiao Yong's motionless back.

Pan Lei had no choice but to approach the window by himself......
