Xu Chu took out the tweezers from the toolbox and carefully sandwiched the maggots into the clean bottle one by one.

After she was done, she explained: "In fact, the living creatures that appear on the corpse, including maggots, ants and flies, can not only guess the time of death of the corpse, but also infer the place of death, the cause of death, and analyze the facts of the case." ”

This involves forensic entomology, and if you talk about it carefully, it is not clear that it can be explained in a few words.

Among them, the most valuable insects such as flies, ants, bees, butterflies, moths, and beetles are the most valuable for practitioners and forensics. For example, green-headed flies and hemp flies can generally smell blood and rush to the scene of the crime within a quarter of an hour, or even ten minutes, after the murder. And if there is a beetle on the corpse, it proves that the deceased has been killed for a long time. The composition and abundance of different insect species vary from the appearance of the corpse to the decomposition and decomposition of the corpse, which is of great significance for the analysis of the time of death of the corpse.

"It's like the eggs are born between twelve and eighteen hours before the body is found. It hatches into maggots, and when maggots grow, it takes three to four days to become pupae, and finally breaks the pupa and becomes a fly. Of course, some female flies produce larvae directly, but it is generally not much different. Xu Chu said as he wiped the tweezers with a cloth towel, and then said, "There are large black blood stains on the ground here, and the blood stains have seeped into the ground. The mask was inferred to have been dropped after the corpse had decomposed, or had been dragged down and discarded, and there were very small flies nearby, so it could be inferred that this was the first scene of the man's death. In this darker environment than the outside temperature, maggots will inevitably grow more slowly. ”

After saying that, she sighed, "It's a pity that we were late and couldn't find the body." Otherwise, based on the maggots' gnawing on the corpse parts, it is very likely to infer the scars on the corpse, or even the cause of death. ”

Forensic entomology is the most mysterious science in forensic knowledge that Xu Chu believes. Even, in previous lives, there were many forensic doctors who specialized in the treatment of insects on corpses.

I remember that there was a case of a couple who died tragically in the living room and bedroom, and it was originally inferred that the husband killed his wife and then committed suicide. However, at the time of the autopsy, it was found that the worms on the husband's body were in the third stage, while the one on the wife's body was in the second stage, which was different from the original speculation. But later, the autopsy personnel found that the air conditioner in the bedroom was turned on at a very low temperature, and because of the temperature difference, the maggots on the deceased's body had different development periods. In addition, the maggot species is the most common type of fly in the local area, and it flies to high places, which corresponds to the upper floor where the deceased lived, so it is concluded that the deceased's home is the first crime scene.

In theory and practice, forensic entomology is of great significance for the examination of corpses in various situations, even decomposing corpses.

It's a pity that the ancient conditions were relatively backward, and many live experiments could not be done, so there would be relatively fewer available means.

But even so, these things that are disgusted by everyone can also help Xu Chu verify something. For example, whether the deceased was poisoned......

The previous autopsy along the way, or the autopsy when it was cold, was not maggots on the corpse. Either the body was hidden in an ice cellar and no maggots were born, so she did not use the study of maggots to speculate on the deceased's dying situation as the main means of autopsy.

If it can barely be regarded as a maggot proof that it is the time when she concluded that Qin Tiezi was not hit on the head and died by the statement that "the corpse was rotten, the skin and flesh were red after being beaten or the blade wounds, and the flesh was dark and black, and the bones were not bad, and the insects could not be eaten".

She said it simply, but Xiao Mingzhu and Cao Xianguan listened very carefully. Xiao Mingzhu is okay, she is a monk halfway, and she has a kind of blind trust in Xu Chu, so she doesn't feel happy.

On the contrary, it was Inspector Cao, after hearing this explanation, the excitement in his heart could not be calmed down for a long time. In the past, when they conducted autopsy, they mostly washed the maggots on the corpses as filth and washed them with vinegar and spirits, but they didn't expect those bugs to say so much.

Thinking of this, he couldn't help but rethink what Xu Chu had just said in his heart, and the more he thought about it, the more reasonable he felt. In this way, he began to rejoice that he was on duty today, and if it weren't for this, he was afraid that he would not be able to learn this.

After checking the mask, Xu Chu got up and walked over to the strange small bed that seemed to be a bed but not a bed. As I got closer, the more I could smell a strange fragrance, mixed with a slight sweet smell.

Instinctively, she pulled the white cloth off it, and then saw the blood stains on the mattress under it. What's more, Xiao Mingzhu found that there were two rows of bottles made of glass under the bed, and inside that bottle was the residual blood that had not yet coagulated. Occasionally, a few were discarded crookedly, with only a layer of dried blood on the walls of the bottles.

"What is this?" Xiao Mingzhu looked at the rows of bottles and cans that were taken out in surprise, "Could it be that there is also a sick man here who sucks raw blood?" ”

Xu Chu held the bottle with an extremely similar test tube, and suddenly had a bad premonition in his heart. After a while, she said coldly: "I'm afraid this is also a thing used in alchemy......

Xiao Mingzhu and Cao Xianguan were stunned, and even the two silent guards subconsciously frowned.

Alchemy with blood...... What kind of demon is this?

Xiao Mingzhu hesitated for a moment and said nervously: "This, this, this can't be human blood!" ”

Xu Chu glanced at her, lowered his eyes and said, "Whether it is human blood or not, it still needs to be tested later." ”

It's just that she already has a guess in her heart about what it is, and even what kind of elixir it is refining for. If that's the case, then the alchemist must be really murderous......

After inspecting the dark room, Xu Chu asked the guards to carry out the Dan furnace and other objects, and she went straight to the two rows of children's corpses that had been arranged.

The corpse that was first seen was a girl with a beautiful face. Looking at the appearance, he is only seven or eight years old, his face is round and delicate, and he is dressed gorgeously, which is quite comfortable to see the days before he was born. It's just that at this time, some of the corpses are still intact, but some of them have been amputated by the waist, or they are missing limbs, ears and nose......

"Who is ruthless, it's so frustrating, such a young child won't let go!" Xiao Mingzhu faced the corpses of several children, and it was difficult to hide her indignation, if she hadn't followed Xiao Qinglang and Xu Chu for a long time, she was afraid that she would be able to throw the whip directly at this time.

Xu Chu glanced at her, and sighed secretly in her heart, when she was angry, annoyed like Mingzhu, and didn't care about the curse of the unknown murderer.

But as she grew up, as more and more corpses were examined, her state of mind was slowly smoothed out. There are many strange cases in the world, and there are people who kill people because of a word, there are those who throw corpses because of impulse, and there are even those who rob and kill women for their own selfish desires. If she is indignant every time, I am afraid that her temper will be like a cannon fight at this time.

And she has neither the capital to indulge her temper, nor the mental strength to maintain that simplicity. All she has is the desire to avenge the deceased, and the idea of bringing the murderer to justice.

Therefore, in fact, at this point, she and Xiao Qinglang are really compatible enough.

By this time, she had briefly examined the body of the first child.

"The deceased, female, was about seven years old and three feet four inches long. The clothes on his body are intact, there are no traces of struggle, and his face is not hideous, indicating that he died quite peacefully. When she had finished describing the deceased's appearance, she reached out and took off the girl's bits and pieces of clothing, not even the profane clothes, and then put the pieces of the body together one by one. Ignoring the gaze of others, she wiped the girl's body one by one with vinegar, and if there was anything suspicious, she also applied a cloth towel soaked in vinegar. "There is a phenomenon of dismemberment, but the wounds are not neat, and there is no pattern to follow. The wound is covered with blood, the skin and flesh at the cut are constricted and protruding, and there is a phenomenon of blood at the end of the blade, which was done before death. ”

Her words made everyone gasp again.

And just waiting for the vinegar to play a role, she looked back at Xiao Mingzhu and asked, "Mingzhu can know that dressing the corpse with vinegar can have an immediate effect?" ”

Xiao Mingzhu saw that Xu Chu deliberately tested her, so she suppressed the depression in her heart, and said in a loud voice: "Naturally not, the vinegar shows the scars through the texture, it will take some time." Half an hour at least, a quarter of an hour at most. ”

Although she didn't find a special book to read, she naturally remembered it when she saw her sister Chu's autopsy.

A quarter of an hour later, Xu Chu unfolded the cloth towels one by one and said directly, "There are no obvious violent and abusive injuries on the body surface, and there are no foreign objects piercing the head and feet and other big holes." ”

"There is severe plaque in the teeth, and there is calculus in the eyes, so the deceased's background is not very good. It can be inferred that she was the one who was sold or sent to be a maid, and then selected to be sent to another hospital. That is, after becoming a maid, before she died, her life was slightly more comfortable, so that her body and appearance became rounded. ”

As she spoke, she took the cotton and sent it to the girl's private parts, because she had the experience of the previous car with the princess Ayidai, so at this time, the inspector Cao did not stop the exit again.

After a while, the cotton was taken out, but there was no trace of blood on it, and it was clean.

Now Xiao Mingzhu already knew what this meant, she was stunned for a moment, and said dumbfounded: "How is it possible, this is a seven or eight-year-old child...... Even if it's a child bride, it's not allowed to ......"

She couldn't say the next words.

Xu Chu's eyes also changed slightly, she frowned tightly, and it took a while to suppress the anger and sadness that suddenly rose in her heart.

She gritted her teeth, forcing herself to suppress the anger that almost burned her sanity. This sense of powerlessness appeared once as early as the Dashicun copper mine case, but I didn't expect to feel it now.

She thought that her state of mind could be calm, but as soon as she thought that her guess might be true, she pursed her lips tightly, and even the hand holding the cotton was trembling slightly.
