In the shed on the right, in the far middle, is a rat that has rotted so much that it can only be faintly recognized. With it as the center, bryophytes have spread throughout the land, and ferns have grown first......

"I didn't expect to really get out what your teacher said?" Xiao Yong said to Boss Huang.

"Exactly...... It seems that Professor Gu's plan is not small. Boss Huang sighed.

"Now, we have basically confirmed that the murderer is the case. But why did he harm the innocent Chen Keke? Xiao Yong asked again.

"Situation one, Chen Keke accidentally saw this kind of human face mushroom, was stimulated and inhaled a small amount of fungal spores, which led to madness, of course, the possibility of this situation is relatively low." Pan Lei said.

"Situation two, remember what I just said, will the mushroom cover of the mother plant cause mental abnormalities if it is seen for a long time? So I guess it was indeed Chen Keke who discovered Gu Jing's plan, but Professor Gu Guo was embarrassed to directly kill the girl that his friend had a crush on, so he deliberately let her look at the mushroom cover of the mother plant for a long time, which caused her to go crazy. Zhang Wei analyzed.

Xiao Yong nodded: "This explanation is reasonable. ”

Boss Huang shook his head: "I admit the criminal process you said, but I don't agree with the criminal motive you said." Because there is also situation three - love killing. From a combination of sociology, criminal psychology, and the psychology of sexuality, I find that Gu Shi's affection for Professor Smith is extraordinary—and that's what I've been thinking about all the way—yes, it's what you think in your heart, beyond the friendship between men. So, I think, Chen Coco did undoubtedly discover this mushroom. But the past can be disguised by experimentation. But his subconscious made him deliberately guide Chen Keke to see the mother plant, which caused him to go insane. ”

Pan Lei and Xiao Yong nodded thoughtfully, but Zhang Wei said with a puzzled face: "What is your basis?" And what is his purpose in doing this? ”

Previously, Smith had repeatedly said that he and Gu Jing were the only like-minded friends. In addition, considering the situation, Smith invited him to camp, and Smith probably didn't even ask where the destination was, so he agreed, and packed everything, which almost delayed his proud protégé, that is, your doctoral dissertation. What does this mean? It shows that there must be an extraordinary trust between them. However, Smith has a crush on Chen Keke, indicating that he has a normal sexual orientation. What about the situation? What did he think of his most important friend? Listening to what you said before, I know that Gu Guo is a person who is obsessed with research, he is not married, maybe he has never talked much about love, and he must have few friends. Smith thinks of him as his only like-minded friend, so why not? Alternative emotions are always bred in a single-sex environment. To sum up, his purpose in doing this is to subconsciously want to monopolize his good friend - Smith. Perhaps he may have attributed it to allowing Smith to be equally fascinated by research. In fact, I just want to be the most like-minded friend with him in everything forever. Perhaps, even he didn't realize that this is the super friendship between men. In syllogism, it is: because Gu Guo has a crush on Smith, and because Smith has a crush on Chen Keke, he wants to get rid of Chen Keke. After saying a long paragraph, Boss Huang took a few deep breaths and said, "And the most important point, considering the situation, he didn't choose to kill Smith, who was the most threatening to his plan, is the best reason. ”

Everyone, they couldn't help but nod.

Xiao Yong had to applaud and said, "Well, it turns out that you are indeed a genius psychologist." ”

"It's a pity that he usually uses it to figure out the teacher's questions and ponder the preferences of girls." Pan Lei said angrily.

"Lao Pan, stay a line, see you in the future! Besides, it's not every day that there are murders...... My talent, don't have a rusty ......"

"Okay, okay, I can't talk about you. Now, all the mysteries have been solved. All that's left is to find the situation and solve the fungal outbreak. Okay, Zhang Wei, I'll leave it to you next. ”

"Huh? But I don't quite understand the killing process of the situation. Xiao Yong said again.

"I'm too lazy to say it, I'll leave it to Zhang Wei to explain." Pan Lei said.

Zhang Wei looked around, walked to the two bare pieces of dirt, squatted down, grabbed some soil, sniffed it, and said, "A single spore is planted with sorrel." As time and temperature change, the sorrel grows completely, and the spores of the human face mushroom wake up, then grow and volatilize into spores to spread. There will definitely be some of them, coming to the windowsill. Because the location of the window sill is the most direct place for the inside of the house to connect with the outside world, there is both abundant water and abundant sunlight. Finally, you also know - the humidity of these soils is around 82%, considering today's weather and indoor conditions, if he has been watering himself, he should have gone out around 3 p.m. As for where it went, I don't see. ”

"Maybe someone knows." Boss Huang said faintly.

"Who?" Pan Lei asked.

"Janitor...... Every time I went out, I had to be arrested and questioned for a long time, as if I were interrogating a prisoner. Boss Huang said.

"You deserve it! The doorman probably thinks you're going to harm the girl. Let's go, go to the door and have a look. By the way, notify the school on the way and seal this place to avoid a second accident. ”

Walking downstairs, Pan Lei continued: "This is the teacher's dormitory in Building 22, and the closest to here is the north gate. ”

Countdown to 8 hours and 58 minutes.

The north gate of Tsinghua University is very small, inside the school, there are many cars parked, and outside the school, there is a small road.

In the security booth, there are two guards on duty.

After Xiao Yong showed his ID, he asked the security guard if he had seen Professor Gu go out at about three o'clock this afternoon.

But the two security guards shook their heads, saying that they had never seen him go out.

Everyone was extremely disappointed, and an elderly doorman said, "What are you looking for Professor Gu to do?" Call him. ”

"Very important thing. Zhang Wei, contact Professor Smith and ask him where Professor Gu likes to go. Then we might have to split up ......"

"Where do you say Professor Gu likes to go? I know. ”

"Uncle Janitor! I would like to hear about it. Boss Huang's eyes moved, and he took out a box of Chinese cigarettes from his pocket, skillfully took out one of them, and handed it to the doorman.

Pan Lei shook his head and said, "Huang Youcheng, you actually learned to smoke." It seems that I need to tell your parents ......"

"Don't! I am, usually sneaking out, means! Boss Huang hurriedly explained.

The doorman took the cigarette, but did not smoke it, but sniffed it, and then put it in his jacket pocket very preciously, and said, "Ouch, it's rare to see such a good cigarette." Let me tell you, Professor Gu, I usually like to go to the Old Summer Palace in the west. Sometimes, I don't come back until three watches in the middle of the night. You can go over there and look for it. ”

"Thanks!" Boss Huang handed over the cigarette again and said.

"Come, I'll take us there." The older doorman said boldly.

Everyone took the school bus to the West Gate again, went out of the West Gate, and in a hurry, took another taxi.

When the taxi driver heard that he was going to the Old Summer Palace, he even said that he was too close to go. Xiao Yong had no choice but to show his ID again. The driver reluctantly pulled everyone to the Old Summer Palace.

"Oh, this car, poor power, poor shockproof performance, low-end enough, should have been eliminated a long time ago." Boss Huang said as soon as he got in the car.

The driver's face turned green, but before he could scold, Pan Lei said, "We've arrived." ”
