When Sima Qiqi heard this description of tetrodotoxin, his eyes looked at it with a flame of hope and asked: "Tetrodotoxin is so magical, so if you analyze the body, can you find signs of tetrodotoxin in the blood?" ”

Originally, he was still immersed in the joy of the mysterious ability of tetrodotoxin, but when he heard Sima Qiqi ask such a question, he looked back at Sima Qiqi and showed an embarrassed smile.

Sima Qiqi saw an unnatural smile, looked at it with a puzzled expression, and said slowly: "In theory, it is possible to find signs of tetrodotoxin through blood analysis, but the magic of tetrodotoxin is that it can be fatal, mainly paralyzing the heart and nervous system, but it will not stay in the body, as long as the body functions return to normal, that is, tetrodotoxin is automatically excreted by the body." ”

Seeing that Sima Qiqi didn't seem to understand, he hurriedly explained: "Let's put it this way, if Li Feng had a heart attack, he drew blood and tested the blood, and he could find signs of tetrodotoxin, but when Li Feng came back from the dead, tetrodotoxin basically did not exist in the body at that time." That's why I said that tetrodotoxin is a strange poison in the world, more deadly than the poison we often hear, and there is no antidote, but if you are lucky and survive 24 hours, this body will excrete tetrodotoxin, and it will be alive and kicking again. ”

Sima Qiqi's eyebrows fluttered when she heard what she said, but Sima Qiqi had a helpless expression, and then noticed that Sima Qiqi's expression was slightly sad, and hurriedly comforted: "Don't worry so much, there must be other ways to confirm this!" ”

When Sima Qiqi heard this, he raised his head and asked, "What method?" ”

Originally, he was in a hurry to comfort Sima Qiqi's words, but he didn't expect Sima Qiqi to be more serious with himself, and asked if there was any way to confirm the guess of the two, unprepared, looking at Sima Qiqi blankly, Sima Qiqi sneered.

"Don't look at me with this expression, I was joking with you just now, you said that the tetrodotoxin in the blood should have been non-existent when Li Feng came back from the dead, what other way can I confirm it!"

Seeing that the light of hope in Sima Qiqi's eyes dimmed a lot, and he didn't know how to settle down for Sima Qiqi, suddenly Sima Qiqi thought of something and sat up straight and watched, looking at Sima Qiqi with a confused expression, thinking: "I have nothing to do, this Qiqi is now looking at herself with hope, and I can't give her any satisfactory answers!" ”

His heart was already hanging, afraid of disappointing Sima Qiqi again, Sima Qiqi looked at him with a solemn face and asked, "You just said that conotoxin is not easy to get, while tetrodotoxin is relatively easy to get, isn't it?" ”

Hearing Sima Qiqi ask such a simple question, he nodded mechanically, and his originally hanging heart fell to the ground slightly, and Sima Qiqi then asked: "Can ordinary people buy tetrodotoxin through the Internet?" ”

Hearing Sima Qiqi ask such a question, he thought about it for a while, and said in a tone of not quite sure: "I'm afraid this is a bit difficult, after all, tetrodotoxin is still a highly toxic substance, and it should still be subject to transaction management!" ”

Sima Qiqi leaned back in his chair, thinking about what he had just said, Sima Qiqi looked at the ceiling and said, "How many people will know about tetrodotoxin?" ”

"A lot."

When Sima Qiqi heard the answer, he instantly sat up straight and looked at it, and asked rhetorically, "A lot?" Do many people know about tetrodotoxin? ”

Hurriedly said: "I think few people will know what the specific effect of tetrodotoxin is, but knowing the fact that puffer fish is poisonous, many people know, after all, puffer fish is delicious, and those who love to eat puffer fish or are interested in delicious food know that puffer fish is poisonous." If nothing else, professional chefs who cook puffer fish know that puffer fish is poisonous. ”

When Sima Qiqi heard this, a flame of hope reappeared in his eyes, and he looked at it and said: "Then this range is much smaller, check if there is anyone around Li Feng who understands the effect of tetrodotoxin and can get tetrodotoxin, this kind of person has a high probability of being the real murderer." ”

Nodding and shaking his head, Sima Qiqi nodded and shook his head again and again, and asked suspiciously: "Why are you nodding and shaking your head, do you agree with my statement or oppose it, is it okay to give an accurate opinion!" ”

hurriedly said: "What you just said is very correct, but there is a question, what is the purpose of such a person, he used tetrodotoxin to make Li Feng die first and then resurrect again, what is the picture?" ”

When Sima Qiqi heard this, he thought for a while and said: "Maybe the real murderer is to avoid investigation, before everyone focused on Fang Qing stabbing Li Feng with a chisel, and ignoring Li Feng's previous heart attack, the prosecutor immediately changed his words after getting the note, although there was no direct evidence to come out, but the prosecutor had hinted more than once in court that Fang Qing used some means to make Li Feng have a heart attack, in addition to the two toxins you said, are there any other biological toxins that can play this role?" ”

"Yes, but it's too rare, and it's harder to get, I guess even the top labs may have it, conotoxin is hard to get, and many people don't understand, if the murderer is as smart as you say, then you should choose the popular poison. Personally, I'm inclined to tetrodotoxin, but according to what you mean, the murderer doesn't seem to attract everyone's attention, so he used some fierce material to kill Li Feng directly, why use this kind of uncertainty to bring Li Feng back from the dead? ”

Sima Qiqi heard the question, fell into a deep thought, this case is really unspeakably strange, if you want to kill, then the murderer should kill Li Feng directly, but Li Feng is also resurrected, according to the saying, there are many drugs that can cause a person to have a heart attack, and it is more stable, although tetrodotoxin is more toxic, but there is an uncertain factor, as said, if the body carries the 24h, then the poisoner is fierce, what is the meaning of the murderer doing this, Sima Qiqi's brain spun rapidly, as if trying to find the root of the problem from this chaotic clue.

When Sima Qiqi rethought the whole case, suddenly Sima Qiqi had a flash of inspiration, Sima Qiqi slapped the table and stood up and said: "I know the murderer's purpose, the murderer wants to kill people with a knife." ”

"Ah, borrow a knife to kill someone, borrow whose knife to kill whom?"

was sitting on the side with a mobile phone to kill time, but suddenly heard Sima Qiqi shouting loudly, so frightened that the mobile phone almost fell to the ground.

Looking at Sima Qiqi, he asked cautiously.

Sima Qiqi said in a slightly excited tone: "Borrow the hand of a frightened person to really kill Li Feng." Imagine what you would do if a person who had been judged dead by a doctor suddenly sat up, or suddenly opened his eyes and grabbed your hand? ”

Seeing Sima Qiqi looking at him with a terrifying expression, he couldn't help but feel the hairs on his back stand on end, and he stammered: "If this really happens, then I must be like the funny video I found for you, punch it directly, and then turn around and run." ”

"What if you keep getting caught?"

Hearing Sima Qiqi ask such a gloomy question, he thought about it and said in an uncertain tone: "Fight to death until you let go of my hand?" ”

Sima Qiqi said excitedly: "That's right, that's it, this murderer is really smart, he has captured the fear of people in front of unknown things, anyone who sees a corpse that was still peaceful one second ago opens his eyes and grabs someone else's hand the next second, no one wants to find out, but to get rid of this terrifying scene as soon as possible, in this case, in order to protect himself, as you said, fight to the death, then those who have tools in their hands will not continue to attack until the hand holding is released." ”

Holding his chin and listening to Sima Qiqi's analysis, he said slowly: "Then according to what you say, this murderer is not only smart, his understanding of toxins can basically be regarded as a genius level, it is simple to kill people with tetrodotoxin, but if you want to let the poisoned person die first and then live, the poisoner will scare those who don't know, and then let the uninformed person really kill the poisoner, then that dose must be exactly the same, if there is no one around, then it is not that the real purpose cannot be achieved." ”

"So, investigate whether there are any people around Li Feng who use this kind of poison, if there is, then it should be the murderer!"

Hearing Sima Qiqi say this, he said slowly: "There are individual differences here, I don't think it's that simple, I'll find Xie Junjie to check, in fact, I don't need to check, since that Zhan Long is a doctor, he should be able to do it, and he didn't show us Li Feng's case information before, and then he took it out in court, this kid is suspicious at first glance." ”

"Zhan Long is indeed suspicious, but this is too obvious, not to mention that everyone has no suspicion of him, so why tell others that Li Feng's heart condition is abnormal, even if it can make people suspect Fang Qing, then Zhan Long himself will be suspected."

Hearing Sima Qiqi express the doubts in his heart, he thought for a while and said, "It seems that this is indeed the case, oops, this case is so annoying!" ”

There is still more than a day before the trial, and in the evening, Xie Junjie called to invite Sima Qiqi to dinner, and was very surprised to hear that Xie Junjie invited him to dinner, and he was still thinking that Xie Junjie actually went out, and the mystery of this matter itself is similar to Li Feng's resurrection.

Came to the agreed hotel with Sima Qiqi, a very small storefront, the two went in, and saw a few guests, Xie Junjie was holding a cigarette with a decadent look, and saw Sima Qiqi waving his hand.

As soon as he sat down with Sima Qiqi, Xie Junjie handed a document to Sima Qiqi and said, "The person you are looking for has not been found, and the only one who meets the conditions you said is this Zhan Long barely compliments." ”

When Sima Qiqi heard Xie Junjie say this, both of them showed expressions of disbelief.
