"Well, I've seen it in a case. ”

Of course, Yan Zhi was referring to the previous case - a foreign spy assassination case, but with the terrible mechanism of action of this toxin, Yan Zhi felt that there must be more cases that had not been discovered.

"Humans, animals and plants are made up of many cells, and the most important component of ricin is ricin. It is a structure of two strands joined together, a chain and a B chain, and the first chain allows it to pass through the walls of human cells. ”

Yan Zhi tore open a leaf and gestured to show them, "The only thing that is poisonous is the B chain, which destroys a vital structure in our cells, and can be free and free without being damaged itself." ”

In other words, a little ricin can destroy many cells, although the onset is a little slower, but this just gives the murderer time to get out, and the process is irreversible, that is, there is no effective antidote. Yan Zhi shrugged, "The perfect assassination poison, isn't it?"

"But apart from the seeds, all other parts of the castor can be used in medicine, and as for what diseases to cure, I don't know. I'm a catcher, and I only care about the parts that poison people. ”

"Whatever is medicine is poison, and whatever is poison is medicine. Pei Jingran sat down and muttered to himself.

He had studied medicine all his life and had never heard such remarks. How can a human being be made up of what cells?

But those words were like someone lighting a lamp from the other side of the tunnel and shining into his original knowledge system. He rushed to the desk like crazy, grabbed a pen and began to note:

"Makes sense, what are cells, tell me quickly!"

Yan Zhi thought about it, this guy has a cabinet of glass instruments, and it is not easy to put together a microscope:

"Well, I'll show you later. Tell me, in this situation, are there any drugs that can kill people, but they are suffocated to death?"

"Who cares about you?" Pei Jingran wrote hard, "If it is verified, this poison contains a structure that can maximize the effect of the drug, do you know how many terminally ill people can be saved!"

Yan Zhi's brows knotted: "You mean, extract a non-toxic armor chain to save people?"

"Yes, if what you say is true, why not?" Pei Jingran looked at her eagerly.

Yan Zhi held her forehead with her hand and sighed again and again. An optical microscope is not enough for this madman to rewrite the structure of proteins, what he needs is the DNA recombination technology that the entire genetic engineering laboratory and biologists have been concocting for hundreds of years.

It's really a trick to make people, and I don't know who is born in the wrong era between myself and this madman.

In order not to dampen the enthusiasm of this scientific pioneer, Yan Zhi pondered the words: "Forget it, it's not something that can be done in a while." It's the kind of poisonous ...... that can suffocate people?"

Pei Jingran lay on the table in a gloomy manner, but still stumbled: "What a good idea, let me think about it again, think about it again......"

"That poisonous ......," Pei Nanxing timidly asked, "Is it the one we have seen in Jeju?"

"It should be. Pei Jingran waved his hand impatiently, "You tell them, don't bother to explain." ”

The three of them looked at the little girl holding the rabbit in unison, Pei Nanxing rarely spoke in front of so many people, and his voice couldn't help but tremble:

"Uh-huh...... A few years ago, when my father and I went to sea, I saw a little girl, who was only ten years old, a little younger than me, and her father and mother were very sad, it was really pitiful...... We poured a lot of licorice to induce vomiting, and tried Changshan and quinoa, which are poisons to fight poison, and finally even used gallium or something, but it didn't work at all. ”

Everyone listened inexplicably, but looking at Pei Nanxing's sweet and delicate little face, they all chose not to attack, nodded and smiled and listened to her continue to gossip.

"We saw how strange her death was, and my father had to see it, and he stuffed a lot of money from other people. After the autopsy, it was found that the water accumulation in each organ was very serious, and the blood vessels were bruised, which was a typical suffocation death. ”

"Ahem, have you found out what the cause of death is?" Su Huan coughed and pulled the topic back.

Pei Nanxing nodded: "Hmm." Before the little girl was taken to the hospital, she ate a kind of dried fish. Originally, the fish meat was not poisonous, but the dried fish didn't know if it was blood or the eggs were not cleaned, so something happened.

"Daddy also deliberately caught that kind of fish, which is particularly poisonous, especially fish blood, which can drag on for a longer time if eaten by mistake, but if it enters the blood directly from the wound, it will be fatal in a matter of moments. ”

Yan Zhi and Su Huan exchanged a look, this should be the poison chosen by the murderer, but it is really ingenious.

"What's the name of this fish?" asked Su Huan reasonably.

"I don't have a name...... "Bae Nam-sung blinked his eyes, "The fishermen over there in Jeju call it 'Redfin Monster Fish', everyone eats it, the fish tastes good when cooked, and I've eaten it." ”

"You're so daring. Yan Zhizhen didn't see it.

"Well, in fact, I quietly fed the dog before eating...... Pei Nanxing looked quite guilty.

Yan Zhi laughed secretly in her heart, she really has a father, and she must have a daughter, only to hear Pei Nanxing continue:

"My father also named it 'Jeju Red-sided Dolphin' because it is very similar to our common puffer fish. I think it's a pretty good name, it's nice and appropriate, but no one calls it that except us. ”

"By the way, Daddy even drew a picture. Pei Nanxing said, turned to the shelf, took out a booklet and handed it over.

Yan Zhi was just about to pick it up, and Su Huan naturally took it. Yan Zhi glanced at him, she didn't expect that he was quite interested in the investigation, and it was estimated that she had listened to too many nonsense about herself, and she couldn't stand it anymore and wanted to find something to do.

However, she thought about it again, maybe it was because the little girl was pretty. Could it be that this ice cube face also moved mortal hearts, can't it?

Su Huan didn't know what she was muttering there, and arched his hand and said:

"Senior Pei, Miss Nanxing, we also found a strange thing on the corpse, I don't know if the two of you can answer?"

"The pupils of the corpse's eyes are not dilated like ordinary dead people, but are shrunk to the size of a grain of rice......

"What! the pupils of a dead man the size of a grain of rice?" Pei Jingran stood up and rubbed his hands excitedly:

"Lao Chen is too boring, he didn't tell me such an interesting thing, because I invited him to drink every month......

Yan Zhi's heart was clear, and sure enough, Pei Nanxing shook his head: "This ...... It's also the first time we've heard of ......."

Yan Zhi actually guessed what was going on with that pupil. Originally, I thought that with the level of production of this dynasty, I should not be able to get that kind of substance.

But with the contents of this house, perhaps, it is not impossible to make it.

One of the best painkillers to date, one of the most ecstatic poisons, the honor and nightmare of a criminal investigator......

"Sister, are you okay, your face is suddenly so bad. Pei Nanxing's voice was like a heavenly sound, which shocked Yan Zhi's demonic shock.

Yan Zhi reluctantly smiled and shook her head. Everyone saw that she was fine, and chatted a few more words, and then said goodbye to the Pei family's father and daughter.

By the time they came out, the stars in the sky had fainted, and a layer of white light was faintly shining through the dark blue sky.

On the Shangjing River in front of Xianhe Street, you can see the new shoots of weeping willows on both sides, like a few pale green ink marks, stained in the dark color before the morning light.

Yan Zhi yawned, and was thinking of some excuse, so she casually sent Su Huan away, and heard this person say slowly:

Since it was not early, Su took his leave. I don't know how fast Yan catches, can I invite you to Yinghualou to the banquet today?"

Yan Zhi is nothing, why don't you just have a meal in Qinglou, and you can't eat when you investigate the case.

However, Wei Huan's mouth was wide open, and it seemed that the criminal department had never seen the world, which was really embarrassing.

However, Su Huan's next sentence really made Yan Zhi angry.

The figure turned around leisurely, and a faint sentence floated in: "Dress like a woman." ”

Can this be endured?" Yan Zhi patted the set of clothes on her body, and a wry smile appeared on her lips, "What do you mean by dressing like a woman, isn't this girl like a woman? ”

Wei Huanxin said that what they said was right, but there was no need to repeat it in front of Yan Zhi.

"This girl didn't have time to bother with him, so let him go. Yan Zhi stared at Su Huan's distant back and narrowed her eyes, "In other words, he won't appear before today." In that case, let's get everything done. ”

Wei Huan knew what she meant, glanced at her, and didn't speak.

"Come on, it's just a routine investigation. Yan Zhi waved her hand, "Do you think that if we don't follow, Su Huan's fox will let go of the gang of people in the criminal department?"

"It's always a colleague, it's too embarrassing to look up. Wei Huan looked embarrassed, "And I heard that Master Xie was also imprisoned last night, did you even check with Xie Tou'er?"

"Nature together. However, if Xie Tou'er did it, we might not be able to find out. Yan Zhi answered casually, and the words changed, "It's just that you don't think that the prison scene, how can you say it......"

"It was so clean. This word has been lingering in Wei Huan's mind for a long time.

"Yes. Under normal circumstances, there will always be clues at the scene of physical witnesses, but this time there are no clues at all. Yan Zhi bit her lower lip with her teeth, and her hand unconsciously stroked her cheek back and forth.

"Twenty-one people died, with no murder weapons, no blood, no eyewitnesses...... There is not even a motive. Cause of death is the only card we have in our hand. "

"The unlocking is unambiguous, the poison is clean and beautiful, and the time and place are just right......" Wei Huan's gaze slipped away from Yan Zhi's face and moved towards the sparkling waves on the surface of the river, where the soft willow branches were swaying slightly, "What kind of person is the murderer?"

Suddenly, Wei Huan remembered something wrong: "If the cause of death is the toxin of some fish, how do you explain the pupils of the corpse?"
