"Hey, it's time for you to behave......"

On Xianhe Street, Yan Zhi stood in front of the Pei family's house and didn't want to knock on the door.

"This ...... On a big night, I'm a big man, what should I do if I scare people?"

Wei Huan obviously didn't want to go either. Su Huan looked at her with his hands behind his back, and he didn't look like he wanted to help.

Yan Zhi threw them a look of contempt, asking for the use of these men, gritted her teeth and stepped forward and knocked on the door.

After a few knocks, the door squeaked open. On the way to come, Yan Zhi did a lot of brain supplements to a "madman who knows medicine", but the one in front of her has nothing to do with her own imagination, and it obviously has nothing to do with half a dime.

I saw a little girl in a bright yellow shirt, with a one-color tassel hanging from her beard, and her skin was like fine porcelain. She was only fifteen or sixteen years old, holding a little white rabbit in her hand, with a surprised face, looking at Yan Zhi with her head slightly sideways, her round eyes flickering, and her long black and curled eyelashes, like the tail feathers of a swallow, flew between her eyebrows and eyes shining with stars.

"Sister, are you looking for me?"

The little girl yawned lazily, and the deer's eyes were filled with misty moisture.

Yan Zhi didn't come back to her senses for a long time, how could there be such a little girl in this world? This is too ...... It's cute, isn't it?

"Are you Pei Jingran?"

Wei Huan caught up, his eyes widening.

"Oh, you're looking for my father. ”

The little girl lowered her eyes, pursed her lips, and turned sideways to let them in. "I'm Nanxing, Pei Nanxing......"

Yan Zhi didn't raise her legs, but was worried, "In the middle of the night, you just let us in, aren't you afraid that we are bad people?"

"No," Pei Nanxing's deer eyes became rounder, and he shook his head in a daze, "My sister and brother are all upright, how can they be bad people?"

Yan Zhi swallowed the urge to question her with difficulty, and nodded with a wry smile.

Wei Huan had already slammed into the door, with a wicked smile on his face, and pointed at the tip of Nanxing's nose and said, "Wonderful, the little girl's eyes are not bad......"

A moment later, Wei Huan had already taken Su Huan's jade Buddha and drank tea at the Pei family pharmacy. That's right, Bai Cheng is like that, and he still has a cold face, isn't he a Buddha?

Yan Zhi thought secretly, but she didn't want to sit down. Mainly because of the Pei family's pharmacy, the scale is too amazing. She stood in the middle of the room and looked around, "How many drawers are there, a thousand? No, no, no...... At least two thousand ......"

"Two thousand seven hundred and fifty-five, but my father recently opened another cabinet to contain his new discoveries. Pei Nanxing put down the tea tray and picked up the rabbit and walked over.

"More than two thousand seven hundred!" Yan Zhi exclaimed, "Do you know what is in each drawer?"

Pei Nanxing lowered his head and thought for a while: "Most of them are herbs, not only our Chinese herbs, but also the herbs that my father bought from other countries when he went to sea before......

"In the drawer over there are animal scales, horns, powdered from the guts of dried fish, whole toads and snakes......

"Here are some ores, sulfur, arsenic, calamine or something, which can be used in medicine and cannot be used in medicine, and there are ...... here."

Yan Zhi was amazed, when she was at the Public Security University before, Yan Zhi had taken toxicology. The pharmacy in front of him, in terms of rich collection of materials, seems to be much better than the national key laboratory of their school.

Suddenly, her attention was drawn to a row of shelves by the window, where there were large bottles more than a foot high, containing some kind of clear liquid, which contained scorpions, snakes, toads, and a pile of jellyfish-like things floating quietly.

"Your father, your father is amazing!" Yan Zhi pointed to those bottles, she was not surprised when she came to this world, but this is true......

Probably because his expression was too exaggerated, Pei Nanxing showed a confused expression, "You mean those medicinal wines, Daddy said that wine can increase medicinal properties, but this method has been used for a long time, nothing remarkable......"

"No, I mean the bottle! Your dad actually made a clear glass jar without impurities, and the blowing process is also very mature, you see how well the frosted interface of this jar is done. Yan Zhi used to stay in the laboratory every day, and when she saw this, she couldn't help but be excited.

"Oh, you mean this. Pei Nanxing walked to a cupboard and opened the door like a trick, "It's all my father when he went to Haiguo, he bought it back, he can't do it......"

In front of Yan Zhi, there is a complete set of modern chemical laboratory instruments, in addition to complete sets of glass beakers, test tubes, Erlenmeyer flasks, as well as graduated cylinders, balances, and even alcohol blowtorches with accurate scales, thickness, slenderness, and length, regulating different condenser tubes, and suction filter bottles...... There are a few devices, and Yan Zhi doesn't know what they're used for.

"My God......"

If Pei Nanxing hadn't said that he bought it just now, Yan Zhi would have thought that Pei Nanxing's father had packed the equipment for the entire laboratory, and then crossed over with a tick.

"My father said that it was convenient to buy and fill the medicine, and he didn't need to ...... it," Pei Nanxing blinked, "When I was a child, I used it to fill plum dew and broke a few, and he didn't say much about me...... What, my sister will use it?"

Yan Zhi didn't know how to answer, could it be that she really wanted to take chemistry class here, and she didn't study chemistry either, so she had to say to Pei Nanxing: "No, it's just these things, it looks weird and interesting." ”

"Sister, let's go have some tea. My dad is coming out. Pei Nanxing took Yan Zhi's hand and pressed her back to the table.

"Those things, what's wrong?" Su Huan picked up the teacup and took the opportunity to lower his voice.

"It's hard to say now...... Yan Zhi also took a sip of tea and said in a low voice, "Why does Master Su think so?"

Su Huandang didn't hear it, and continued to drink his tea. Yan Zhi was confused, you asked me, and you didn't speak, which made her feel embarrassed, so she had to say, "This tea is very good...... Hahaha......"

"I added some hibiscus, mint, ginger, honey, and it was good to eat, and even better if I had yuzu and bergamot. Pei Nanxing was very interested, and he looked serious:

"You two are too tired at first glance, so that your liver qi is stagnant and your menstrual blood is not smooth, I'll pack you some medicine and bring it back, maybe it's useful?"

"Hahaha......" Yan Zhi smiled awkwardly, poured a sip of tea, and glanced at Su Huan.

He didn't have anything, but the hand holding the cup stiffened visibly. It seems that this little grandfather of the Chengguo Mansion, who has infinite scenery on the surface, is not as smooth as she imagined.

"Hey, Xiao Nanxing, are you bullying me, why is there nothing in my tea?" Wei Huan drank until this time, and then he saved his taste.

Pei Nanxing cried with a small face, very aggrieved: "But, you look good, and you can't take the medicine indiscriminately......"

"I got it, I got it out......"

A lean middle-aged man rushed out of the room, holding the test tube while shouting, "Xing'er, give me the rabbit!"

Pei Nanxing took a step back, the eyes of the little deer were full of tears for a moment, and he hid the rabbit behind his back: "Daddy, the little rabbit may really die this time." ”

"Don't say stupid things, what am I tossing if I don't die?" Pei Jingran glared at his daughter viciously.

Pei Nanxing was scared in the end, and handed over the rabbit with trembling hands: "If you feed less, I may be able to save it......"

"Yes, yes. If you can't eat it if it's poisoned, you're going to cry again, and you're annoyed......"

Pei Jingran grabbed the rabbit's ears and poured the unknown substance in the test tube into the rabbit. And the rabbit was completely unresponsive, squatting on the table for a while, and was carried back into his arms by Nanxing.

"Is it too diluted, I knew to add less water. Pei Jingran scratched his head, "I'll go get another one." ”

"You dare!" Pei Nanxing was really going to cry this time, "What if the poisoning reaction appears late, you will harm one more rabbit." ”

"Oh, yes...... There can be no rush. Pei Jingran stopped with satisfaction, looked around, and found a circle of unknown people next to him:

"This, this, this... Who are these three people, and how did they get here?"

"Oh, they said it was from the Ministry of Punishment and told you to go for an autopsy. Pei Nanxing hurriedly hugged the rabbit tightly.

"Aren't there Lao Chen and them in the autopsy, we still can't control the living, blast out, blast out!" Pei Jingran waved his hand impatiently, picked up the broom and prepared to drive people away, "I haven't finished the experiment yet." ”

"They said that there was a poison that they had never seen before that poisoned more than 20 people. ”

If Pei Nanxing's words hadn't been said in time, Yan Zhi and the others would have been swept out of the house.

"Haven't you seen it?" Pei Jingran looked disdainful, but the broom was put down, "Your criminal department is quick to arrest, you know what poison is......"

"Toxicology and pharmacology are not separated, everything in the world that is medicine is poison, and everything that is poison is medicine. ”

"It's kind of interesting, go on. Pei Jingran was quite surprised.

Although anyone who practices medicine should know this truth, there are still a bunch of quacks in the world who can never remember it, not to mention that the other party is just a small catcher.

"What the seniors want to extract is the toxin in the castor beans, right?" Yan Zhi said, pointing to the large bundle of green plants piled up on the table.

"How do you know?" At this time, Pei Jingran was completely speechless, the castor was just brought by him from the merchant ship that went north last month, and he dared to say that no one in the whole capital recognized this plant except him.

I just heard that the oilseed cake of this plant after the oil is pressed can poison livestock the size of horses and cows, and I thought it was very interesting, so I asked someone to get some.

"Ricin is rich in castor beans, which are extremely easy to extract and difficult to preserve. The lethal dose is about 20 for adults, about 5 for children, and rabbits...... I don't know how many ...... you put in it."

Yan Zhi glanced at Pei Nanxing with a little embarrassment, she actually liked this little girl a lot.

"It doesn't matter. Pei Jingran coughed embarrassedly, "Do you know this poison?"
