After a hurried lunch, at 2:15 p.m. that day, an edible fungus production base.

Under the sunshine, the plastic greenhouses stretching for thousands of meters rise and fall, and they can't see the end for a while.

The person in charge of the reception is already waiting at the intersection. The eldest lady and the others got out of the car, and after a brief greeting with her, they followed her to the depths of the greenhouse area.

Along the way, the workers who met her would stop and call out affectionately: "Hello Sister Niu!" ”

Sister Niu does not have outstanding appearance, she is one meter and in her early sixties, and her skin is a little black from the wind and sun, just like the most common village girl in the village.

The eldest lady blinked her eyes and said, "Sister Niu, it must be not easy to run such a large base by yourself, right?" ”

"Yes, it is especially difficult for women to start a business." Sister Niu couldn't help but sigh.

"I see you...... It seems that you are not married yet, do you need me to introduce you to someone? ”

"Okay." Sister Niu said with a smile.

"He's ......" Pan Lei felt bad and wanted to hide behind Gu Ju, but he was still pointed at by the eldest lady, "This uncle!" Stable job, rich family background, loyal and honest, it is really a good choice for husbands! ”

"Huh! Miss, you're naughty again! Pan Lei explained to Sister Niu, "Don't listen to her, I'm a policeman, I'm away all the year round, and I have no plans to get married for the time being." ”

Sister Niu smiled and said, "Me too." The police are good, and the violence is good. ”

"It's a 40-year-old man, and it's really worrying to not think about lifelong events......" muttered the eldest lady.

When they came to the porcini mushroom greenhouse area, the eldest lady and her party saw three kinds of fungi: yellow, white and black. Among them, white porcini mushrooms are the most numerous.

"In addition to supplying the whole country, our porcini mushrooms are also exported overseas, and the evaluation is not bad." Sister Niu said with a smile on her face, with an indescribable sense of pride on her face.

"So, these porcini mushrooms must be non-toxic?" Gu Ju squatted down and said after a close look.

"Boletus mushrooms naturally carry some toxins, which cannot be avoided. Therefore, all of our porcini mushrooms and other fungi must be carefully selected and cultivated to ensure that the toxins are minimized. When processing, we have 12 processes, layer by layer filtration, to ensure that there is no toxin residue. Finally, we also randomly sample the finished product to ensure that there are no problems. ”

"It's really watertight. Sister Niu must have a deep understanding of porcini mushrooms, right? I'm curious, how can boletus mutate to produce lethal toxins? The eldest lady asked.

"This ......"

"Let's be honest, we have a case related to mutant porcini mushrooms." Pan Lei added.

"Okay. As far as I know, there are five or six ways to mutate porcini mushrooms. But when it comes to producing lethal toxins, there's only one ...... While it is growing, the roots are soaked in alcohol. ”

"When you grow up, is it okay to water it with alcohol?" Pan Lei asked again.

"No," Sister Niu shook her head, "Boletus mushrooms that are growing or have stopped growing will not absorb enough alcohol, and the toxins produced will not be enough to cause death." But to be honest, even if it is artificially cultivated, the survival rate is not high. ”

"If it grows on its own in nature?" Gu Ju asked.

"It should ...... Possibly. But it happens to grow in a special environment, and the probability of being eaten by people is too low, right? ”

But the eldest lady said: "So there is only one truth, and that is, human intervention...... Understood, Sister Niu, thank you very much for your explanation, what strains are recommended? We want to buy some. ”

"There are specialties, but if you buy them, it's too out-of-the-box."

Before leaving, Sister Niu gave a box of special porcini mushrooms, and the eldest lady also took away some porcini spores.

On the way back, the eldest lady said: "The truth is that the murderer buried something in advance in the place where the porcini mushrooms were collected in Qiantang. Those things, which have a high sugar content, are fermented into alcohol after rotting. Then the killer planted spores on it. ”

"What's that?" Gu Ju couldn't help but ask.

"I guessed it...... It's lychee! There are often car owners who are detected drunk driving because of eating lychees. Pan Lei said while driving.

"So the question is, is it illegal to bury lychees? Is it illegal to grow porcini mushrooms? The eldest lady couldn't help but ask.

"Of course, these are not illegal, but if they are used to harm others, they are naturally illegal." Gu Ju said with a glance.

"What if, the murderer doesn't think he's breaking the law?" The eldest lady threw out another difficult question.

There was silence in the car for a while, and Gu Ju asked again: "But how did she know that Qiantang would eat those poisonous porcini mushrooms?" Our technical team also went to search and found that there was no sign of mutation in the fungi around the picked porcini mushrooms. ”

The eldest lady looked up, looked at a bird looming in the clouds, and said, "This can only be said that she must have observed Qiantang for a long time......

After speaking, she smiled and said, "Uncle, Sister Niu is such a good person, don't you really think about it?" ”

"Of course...... Don't think about it! ”

"Is it because she's not pretty enough? Isn't it high enough? ”

"It's not...... It's like when I see women on the road, do I have to like it? I'm not an animal. ”

"But what do I think...... Do you have someone you like? ”

"If I have someone I like, why don't I know?"

"I guess...... Is it Huang Liya? ”

"Not ......"

"That's Zhang Weiluo? I'll just say that you usually look at each other......"

"Poof...... More unlikely! ”

"Hahaha...... Just kidding, look at the ...... that makes you nervous."

Along the way, the eldest lady and her entourage spent a lot of effort to find more than a pound of lychees from the corner of a food refrigerator.

When she came to the forensic appraisal center, the eldest lady immediately found pots and soil, buried the lychees in the potting soil, then sprinkled the porcini spores on the surface of the soil, and finally wrapped the whole pot with a large plastic bag.

"Next, it's time to witness the miracle!" After the eldest lady finished speaking, she waited on the side.

"However, it takes a long time for the fungus to grow, it seems to take a week to half a month......," Gu asked puzzled.

"It's normal for things to be like this. Unless......" Pan Lei said hesitantly.

"Unless what?" Gu Ju asked suspiciously.

"Unless you add a magic spores. That's another case I handled before......" Then, Pan Lei briefly told Gu Ju about the smiley mushroom. (See the chapter "Botanical Paradise" for details)

After listening to this, Gu Ju was stunned for a while before he said, "Parasitic human body? Reusing the human body as nutrients to create a plant world? Oh my God, that's crazy, isn't it? ”

"yes, it almost worked...... But, alas," Pan Lei sighed, continued, "although most of the dangers were resolved by then, there were still many deaths from fungal infections. ”

Gu Ju patted him on the shoulder and said, "It is up to people to succeed, and it is up to heaven to make things happen." Now that we're alive, prove that you've done a really good job. I can feel that this isn't the first time you've saved the world. I'm not qualified to speak for all of humanity, but I can say to you on a personal basis – thank you! ”

Pan Lei scratched his head, smiled a little embarrassedly, and said: "I am also a policeman, and it is my responsibility to protect the safety of people's lives and property, but the scope of my responsibility is a little larger, and it is essentially no different from what you do." ”

This laughter, only those who have experienced it firsthand, understands that it is the responsibility of exhaustion, danger, unknown, and honor left behind.

Then, he remembered something and said to the eldest lady: "However, I remember that all the materials and fungal spores have been sealed by the state, eldest miss, where did you come from?" ”

The eldest lady smiled slyly: "Hehe, uncle, what did you say?" Why don't I understand? Hey, you see, porcini mushrooms seem to have grown, it's amazing! ”

Seven or eight small yellow mushroom caps, at a speed visible to the naked eye, stretched open the soil......
