The three-day deadline has arrived, but Guan Rui has no new clues, so he can only release Yan Yu from detention, and it is natural for Yan Yu to come to the police station to receive a certificate of release.

However, Guan Rui's face is not good-looking, and Yan Yu will not touch his head.

"Teacher Yan, this is proof that you can go back if you sign this place." There weren't many people in the police station, and it was said that they had gone to protect the archaeological site.

Yan Yu glanced inside, and while signing, he asked casually, "Where is Guan Rui?" ”

Wang Guoqing pouted inside: "It's inside." ”

Yan Yu finished signing, put down the pen, and said to Wang Guoqing: "I'll go in and say a few words to him and leave." ”

"He's not in a good mood, you'd better not mess with him......"

Yan Yu patted Wang Guoqing's shoulder: "Thank you for reminding you." ”

Without waiting for Wang Guoqing to stop him, he had already walked into the office area, there were five or six desks in it, and Guan Rui was in the corner, and when he raised his head, he saw Yan Yu, Guan Rui's face was a little difficult to see.

Yan Yu walked forward, pulled a chair and sat down, and said to Guan Rui, "Why don't you go into the mountain to find that person?" ”

"If you just want to say something cool, get out of here."

At this point in time, Qin Dayou naturally couldn't help him find a guide, two people died in the mountain, and no one had the courage to take Guan Rui into the mountain again.

Besides, only a few people such as Qin Dayou knew the way in that place, and Qin Dayou was now sitting in the village, so it was impossible for him to be his guide.

Yan Yu smiled: "Do you want to check the dancing noodle master?" ”

Guan Rui leaned forward, but quickly fell back: "I asked, Qin Dayou is afraid that people will dig up the dragon vein, and he will take people to guard the temple all day long, and he can't drive him away. ”

Yan Yu had already expected it, lowered his voice at this time, and said to Guan Rui: "I have a way, but ......"

Guan Rui suddenly became vigilant: "You want to participate in the investigation? Don't think that letting you out will clear your suspicion, it's not over yet! ”

Yan Yu sighed: "Since this is the case, then I can only go by myself." ”

Guan Rui also stood up: "What do you tell you to go by yourself!" If you obstruct the investigation, you are obstructing official business! Don't mess around! ”

Yan Yu also became serious: "The noodle man actually gave the child belladonna, this is definitely premeditated, although I don't know what these two children can attract them, but if they don't find out for a day, the child won't be safe for a day!" ”

"Belladonna?"

Looking at Guan Rui's expression, Yan Yu also suddenly said: "The report from the technical department hasn't come out yet, right?" ”

He took out the belladonna fruit and handed it to Guan Rui: "This is belladonna, you will hallucinate after eating it." ”

Guan Rui reached out to take it, but quickly questioned: "How do you know this is belladonna?" ”

Yan Yu pushed his glasses: "It's okay to read more books, it's convenient to check the case, you don't have to wait for this." ”

In the face of Yan Yu's ridicule, Guan Rui didn't have a temper, but he seemed to have figured it out, and asked Yan Yu, "How are you going to check?" ”

This is equivalent to acquiescing to Yan Yu's proposal, Yan Yu also relaxed, and said to Guan Rui: "When I went to Qinjiaao that evening to find someone to help, I saw those masters. ”

"You've seen it?" Guan Rui became excited.

"Listen to me, those people are all mysterious, they can't be recognized when they see them, and there must be seven or eight of them in total, even if Qin Dayou is willing to provide information, we can't investigate them one by one in a short time."

"And what are you going to do?" Yan Yu said it head-to-head, Guan Rui seemed to enter the rhythm of discussing the case with his colleagues, completely forgetting Yan Yu's identity and his dislike for Yan Yu.

"I have to check it from here!" Yan Yu twisted the fruit in his hand.

"From belladonna? How to check this! Guan Rui inevitably glanced at Yan Yu.

But he touched his chin and seemed to find some ideas.

"If you can hallucinate, it means that this thing is poisonous, and the poison will be controlled, let's go to the pharmacy to check the flow? But what if it's homemade? Checking the pharmacy doesn't work......"

Yan Yu smiled: "I don't want to say in my heart, but my body is very honest." ”

Guan Rui was a little embarrassed, blushing and said, "Tell the truth!" ”

Yan Yu gently placed the belladonna on the table and slowly analyzed.

"Although this thing is poisonous, it has an antispasmodic effect, and is generally used to relieve stomach problems, although the whole plant can be used as medicine, but generally speaking, roots and leaves are used, and the fruit is rarely used."

"And you see that this fruit is completely air-dried, and has not been exposed to the sun and concocted, why is that?"

"Why use fruit and not other parts......

Guan Rui pondered for a moment, and said to himself: "The reason why fruits are used is because fruits can attract children and coax children to eat, but roots and leaves cannot. ”

"Correct!" Yan Yu snapped his fingers, and then said to Guan Rui: "But you must know that belladonna doesn't like cold, and it can't withstand the heat, and our place is not suitable for planting at all." ”

"Going around and around, or do you want to check the pharmacy?" Guan Rui was inevitably a little displeased, but Yan Yu shook his head and said, "No." ”

"I just said that it is not suitable for planting, but if I didn't say it, it must not be planted, and if you want to plant, you just need to meet these conditions."

Guan Rui seemed to faintly grasp something, lowered his head and muttered for a moment, and then his eyes suddenly lit up: "Warm house!" ”

Yan Yu nodded and continued to guide: "If you just plant one plant, it's not cost-effective, so in addition to belladonna, there must be other medicinal plants, so this greenhouse should not be small." ”

"Comrade Guan Rui, think about it, this place is so arid, drinking water is a problem, who would use water to grow things, and spend so much effort to build a special greenhouse?"

"The scope of such investigation conditions has been narrowed to a minimum, do you have any impression that they meet?"

Guan Rui thought for a long time, and shook his head: "For a while, I really can't remember, I haven't been here for too long, and I'm not so familiar with ......."

Yan Yu was not discouraged, and pouted outward: "You are not familiar, someone is familiar with it, don't you know if you ask the old comrade?" ”

Guan Rui's dim eyes lit up again, and he was about to go out to ask Wang Guoqing, but he stopped again.

"What if I find it? Such a large greenhouse, growing medicinal plants, because it is used to sell, even sells a lot, what if he sells it to other places? ”

Yan Yu shook his head and smiled bitterly: "This place is poor in materials, and the goods from outside are almost the same, who will sell them?" Besides, if you grow it in a place that is not suitable for growing belladonna, you must sell it in a place that is suitable for planting, and this person's business must not be lost! ”

Although Yan Yu's analysis is not unreasonable, Guan Rui is a little skeptical, after all, he has always believed in professional criminal investigation technology, and he does not recognize Yan Yu's pure reasoning.

But at the moment, there are only two clues left, and there is no way to go into the mountain to track down the mysterious person, and you can only investigate the side of the noodle man first.

Yan Yu was not in a hurry, sat and waited for a while, and then saw Guan Rui walking back briskly, still holding a small note in his hand.

"Found it!"

He couldn't hide the excitement on his face, spread out the note, and said to Yan: "There were originally a lot of medicinal herb merchants in the county, but because of the weather, they couldn't do it anymore, but ...... However, Wang Guoqing knows that there is a century-old brand, and if someone really has the ability to plant, it can only be this one! ”

Yan Yu was also a little excited: "Where is it?" Far from it? ”

"Just outside the city!" Guan Rui nodded vigorously at the address on the note, unable to hide his joy at finding a new clue.

"So what are you waiting for! Let's go! Yan Yu immediately stood up, but Guan Rui pushed him back into his seat.

"I didn't promise you to participate in the investigation, you honestly go back to Laohe Fort, and I will inform you when there is news."

Yan Yu didn't expect Guan Rui to "cross the river and tear down the bridge", and immediately frowned: "It's not interesting for you to do this." ”

Guan Rui smiled "insidiously": "One yard is one yard, you are the people, and it is not appropriate to participate in the investigation." ”

"I'm assisting in the investigation, isn't it a family of police and people?" Yan Yuzi will not give up.

Guan Rui still shook his head, and Yan Yu could only resort to the last method.

"Guan Rui, you don't want me to go, but you have to regret it, it is estimated that there will be a lot of medicinal plants planted in the greenhouse, if people deny it, can you recognize what the fresh belladonna looks like?"

When Guan Rui heard this, he was also stunned for a moment, but he gritted his teeth and could only compromise: "You are only allowed to follow, not to mess around!" ”

Yan Yu smiled: "Don't worry, I understand." ”

It is already very difficult to make Guan Rui, who is so principled, promise to follow him to investigate, and Yan Yu is not good to get cheap anymore and be obedient.

Although he was only going to investigate the medicinal herb dealer, Guan Rui was still "fully armed" and tried to bring all the equipment he could, which made Yan Yu a little nervous.

Out of the police station, the scorching sun was in the sky outside, the floor was smoking, and there were few people walking around on the streets of the county seat. ”

Guan Rui's face was a little unsightly, he pointed to a dilapidated bicycle parked in the corner on the left, and said vaguely: "What about this......"

"Bikes? Just one? ”

Guan Rui also knew that he couldn't hide, so he had to answer in a sullen voice: "The car in the institute went to meet the archaeological team, and the others went to the Laohe Fort protection site, it would be good to have a bicycle!" ”

Yan Yu also smiled bitterly, at this time Guan Rui had already sat up, and said to Yan Yu: "Why are you still stunned, come up!" ”

"I ...... I'm in the back seat? ”

Guan Rui's face turned red inexplicably, and he stiffened his neck and said, "You...... If you don't sit, just run! ”

Seeing that he was about to kick the bicycle out, Yan Yu could only sit obediently in the back seat, but he didn't know where to put his hand.

It's embarrassing......
