Mo Haiyou continued: "Just like the black cat in front of you, you can see that its limbs are spasmodic and contracted, and there are blood cerumen in its ears and eye sockets, which is a blood clot embolism. Apparently dying from a nerve paralysis toxin, it is more likely to be snake venom, and the toxin often does not appear too obvious on the surface. After the death of the black cat, the murderer deliberately plucked all its fur and put it on the balcony for us to find out, why is this? ”

"Still like Liu Yun's corpse, the murderer wants to temporarily cover up the real cause of death. Liu Yun's body was pieced together by the murderer, which brought us two problems, first, based on Liu Yun's head, shoulders and arm parts alone, we have no way to judge the real cause of her death, even if it is reluctantly judged, there is a great possibility of deviation. ”

"Second, as a woman in the other part of the corpse, we have no way to know her identity on the spot, and if we are sloppy, we may think that Liu Yun died of poisoning and make a wrong judgment."

"Maybe all the killer wants is a little bit of time before we do a detailed autopsy, but what I don't understand is, what can he do with that little bit of time? The murderer did this, and his purpose must have been intrinsically linked to the two bodies. Xiaoyao, what do you think? ”

Yun Yeyao squatted there and pondered, he did not answer Mo Haiyou's words immediately, but repeatedly observed the corpse of the black cat. Suddenly, he asked a very strange question, "Xiao Zuo, do you think this murderer really understands snake venom?" ”

"What do you mean?" Mo Haiyou stopped the movement in his hand and asked.

"This is Liu Yun's home, if anyone can kill the black cat, Liu Yun must be the first suspect." Yun Yeyao said: "Xiao Zuo, the black cat has been dead for more than a month, and Liu Yun's death time was less than 12 hours when we found out, these two points come from your judgment, right?" ”

"Yes."

"Then think about it, why did the black cat die in front of the hostess? And there are so many days in between, in this month, Liu Yun can't not go home for a day! Look at the condition on this balcony, everything is cleaned up, and the cardboard boxes don't look like they've been moved recently. Because after moving the carton, there are marks left on the tiles underneath, and it should have been left for a long time. ”

"Therefore, I judge that the black cat was not taken from here for a long time after its death. If someone killed the black cat outside, and secretly put her body on the balcony while Liu Yun was not at home, Liu Yun would definitely find it when he came back. When a person discovers that her pet is dead, she can't have no reaction. Wait a minute, we can ask the neighbors and merchants in the surrounding area, if they know about the death of the black cat, it means that the black cat was not killed by Liu Yun, if they don't know, it's hard to say. ”

"Xiao Yao, be concise, say the result, in front of me, I don't need you to explain the process step by step." Mo Haiyou's heart is now hanging on Liu Yun's corpse, so he doesn't want to waste any time.

Yun Yeyao said: "What I said is actually the same as what Xiao Zuo thinks, just now you said on the phone that there may be more than one black cat and one animal corpse here." Why? Because you guessed that the black cat could not have been killed by someone else, this point was clear from a long time ago, it was Liu Yun's experiment, more accurately it was a method for Liu Yun to debunk the murderer. I can also guess that even if we asked all the neighbors and merchants in the surrounding area, not only would they not know about the death of the black cat, but they would not even know that Liu Yun had a pet. ”

"Although the cat is a proud animal, it has the advantage of having a good relationship with its owner, and if it stays at home all year round and does not let it out, it is not very good at barking. And the more strangers there are, the more silent the cat becomes, so it's easy to avoid the eyes and ears of neighbors. ”

"Liu Yun may have known that someone was going to work against her, and guessed how she would be killed. This is not very convincing, though, because most people who guess they are about to be killed will run away. But I just have this intuition, Liu Yun knew that she might die, but she didn't run, and even arranged everything in this room, waiting for the police to investigate. ”

"We won't discuss the reason why she did this now, to sum up, Liu Yun may not know snake venom at all, and she has never raised poisonous snakes, she has been using cats as test subjects since a month ago, Xiao Zuo, how many doses of various toxins can be lethal, and can keep the surface from showing too obvious traces, you know this much better than me."

In order to fully express the fact that the murderer wanted to kill people with snake venom and didn't want people to find out too soon, she must have killed more than one cat, and the failures of other experiments may have been buried or discarded by her. And plucking the hair from the black cat's body is not only so that we can see the kitten's skin clearly, but also so that he can determine how effective the experiment is. ”

"If the murderer had done these things, he would not have left us any detectable clues in the house, and he would not have killed the black cat so many days in advance. Besides, since he wanted to delay the discovery of the truth about Liu Yun's death, how could he leave a similar black cat corpse in this room? To use the simplest analogy, positive and negative can only be negative, and negative can always be positive. ”

"One camouflage thing can temporarily blind our vision, but two camouflage things can only say that the murderer is debunking his own tricks, Xiao Zuo, you see, didn't we find the corpse of the black cat, and immediately knew the hidden connotation? Therefore, this corpse may only be left by Liu Yun, and we can only find more cat corpses from the surrounding area, and it is impossible to find any poisonous snakes. ”

"That's true." Mo Haiyou said: "Xiao Yao, there is another point, the reason why the black cat will be placed for more than a month is because someone deliberately wants to let it rot, and the corpse spots produced after poisoning are not the same as ordinary corpse spots, most of them will be red, and there are also gray-brown, Liu Yun cannot kill the black cat at the same moment when he is in danger, and the corpse will appear within 5 to 6 hours after death, and then last for about 6 to 12 hours." ”

"Liu Yun can't let us see the corpse spots, because when we see the corpse spots, we will immediately find that the black cat was poisoned and died, so she will not be able to fully express the murderer's thoughts to us. So her only option was to let the corpse completely decompose, and let the corpse spots disappear completely. ”

"The murderer may have to delay 5 to 6 hours before the formation of corpse spots, the reason why he scratched another corpse as Liu Yun's body is incomplete, is also to cover up the corpse spots produced after poisoning, and Liu Yun's face and shoulders, in order to let us determine the identity, he can't destroy it, as long as Liu Yun herself appears corpse spots, she will immediately find out that she did not die of poisoning, and the part of the body below that does not belong to her, it is easy to find out the cause of death."

"In this way, we will know that there is not one, but two female corpses in the warehouse, so the murderer will only have five or six hours, or even less. In other words, he wanted Officer Xie not to know the secret of Liu Yun's existence before entering the lavender villa. Of course, all of this is still speculation, so we need to get the results of the autopsy as soon as possible and find a way to inform Officer Xie. ”

"Now we don't know exactly what the murderer's purpose was? This point is the most dangerous, he needs a policeman, but he has managed to keep me and you out of the Lavender Villa, which shows that the murderer knows the three of us very well, and he must have carefully studied our past. So, Xiao Yao, now I'm also starting to worry about Officer Xie. Mo Haiyou stood up, and he showed a worried look that he had never seen before.
