Li Xiang put on a white coat, carried the toolbox at the door of the office, and walked out of the office with the man.

I followed him all the way to the parking lot and got into a police car.

"The master is on a business trip, and this time it's up to you!"

In the car, the man looked at Li Xiang for help.

"Don't, don't rely on me, I can't."

"Not on you, on whom? I'm even more unreliable, I'm a forensic assistant, I can carry the body, I can hold a scalpel, my hands are shaking."

"Your hands are shaking, your hands are shaking, and it's not surgery, you're still worried about being complained!"

「……」

The two were chatting in the car, and Li Xiang also knew some of the situation of the person in front of him at this time.

His name is Zhang Yongliang, and he is an assistant in the forensic department, not a formal forensic doctor, but he is also working hard in this area.

Li Xiang listened, this is the end of the calf.

The last copy also had a high finger marksmanship, but now it's okay, both of them are half a bucket of water, no, there is no water in their bucket at all.

But Zhang Yongliang felt that the water in his bucket was very full!

The police car soon drove to National Highway 339, and after driving for a while, Li Xiang saw a small forest, next to the forest, several police cars were parked, and the police used a cordon to enclose the grove.

"The comrades from the forensic department are here."

"Please come in!"

After Li Xiang got out of the car, he walked into the cordon with a toolbox.

"Hello, I'm Wang Tianjun, the captain of the criminal police, this time Elder Qin is here, how hard it will be for you."

"It's okay, it should be!"

Li Xiang was very calm on the surface, but in fact he was very flustered inside.

You let him fight and catch the thief, and he is duty-bound.

But when you asked him to dissect the body, he was a little flustered.

The weather in June was a little hot, and Li Xiang's nervous forehead was slightly sweaty, he secretly cheered himself up, and followed Zhang Yongliang into the dense forest.

As the distance approached, Li Xiang could already smell a very foul rancid smell, in the hot weather, such a smell was simply suffocating, even if he was wearing a mask, he wanted to take a breath of oxygen slowly.

But the actual conditions did not allow it, so he had to hold his breath, he couldn't hold it back, and quietly inhaled a little, as if he took advantage of the smell to react and took a breath of oxygen.

There were red-headed flies flying everywhere in the dense forest, and there were quite a few policemen squatting on the ground in front of them, carefully surveying the crime scene.

In modern criminal investigation, the division of labor has been very detailed, and solving the case no longer depends on the reasoning of a certain detective, but the cooperation of various police departments to summarize all the clues to solve the case.

Li Xiang used his white-gloved index finger against the tip of his nose outside the mask, the smell here was even more smoky, he admired these policemen squatting on the ground to work, how did they overcome this smell?

Although he has also been involved in several cases, he has either just died, or he is already in the form of bones, and it is the first time he has encountered a highly decomposed corpse like this, but he did not expect that he would have to dissect her for the first time.

Isn't this embarrassing for honest people~

With apprehension, Li Xiang finally saw the goal of this trip.

It was a highly decomposed corpse, and the deceased was either male or female.

Identified by the hair, the deceased should be a woman, lying on the ground in a prone position, and the whole body is basically in a state, with only a pair of feet with socks.

The body was crawling with maggots, and there were all kinds of ulcers on the skin, and maggots were burrowing in and out of her skin, so that Li Xiang, who did not have a dense phobia, also felt that her scalp was numb, and her stomach was tumbling, and she wanted to vomit something, but she restrained the urge to vomit and swallowed it hard, not to mention how uncomfortable it was.

"Well, this corpse has been here for a while, and this maggot has grown so big."

The maggots on the corpse are not the white maggots that you usually see, but they are a little blackened, which makes it even more disgusting, compared to black maggots, Li Xiang thinks that white maggots are also quite cute.

In addition to maggots, there are many other insects, like a feast for insects.

"Corpses, you

You can take it with you, we've pretty much done the survey."

The technology and the on-site investigation work are almost complete, and the body can also be brought back, so Zhang Yongliang took the body bag and prepared to pack the body, and then take it back to the forensic autopsy room.

"Li Xiang, take a hand."

Li Xiang looked at his snow-white gloves, he really didn't want to get started, but looking at Zhang Yongliang's expectant eyes, he still gritted his teeth: Anyway, I have to dissect it in a while, what is it to move it now?

Thinking of this, he endured the discomfort in his heart and moved the body into the body bag with Zhang Yongliang.

"Let's go, go back to work."

Li Xiang really wants to quit the game and quit doing it, this forensic doctor is really not a human thing, even if he deals with corpses every day, this rancid smell is really unbearable!

After moving the corpse, Li wanted to take off his gloves, and felt that he had a corpse smell on his hands, which was really not so easy to remove.

In order not to get stuck in the copy, this copy still has to be cleared, Li Xiang can only comfort himself, there are many skills, and after playing this copy, he can learn a professional skill again.

In the dissection room,

With Zhang Yongliang's help, the body was moved onto the autopsy table.

"Li Xiang, let's start!"

"Beginning?"

Looking at the corpse in front of him, Li Xiang didn't know what the first step should be, how did he start?

"Yes, let's go."

"I won't!"

"Don't make a fuss, you're a serious forensic doctor, won't you?"

"You don't know at all?"

"Well, I'll do a little."

"Then you start."

Regarding forensics, Li Xiang really doesn't know anything at all, anyway, in the copy, he is not ashamed, among the two people present, Zhang Yongliang's half bucket of water is obviously stronger than him, but not much.

"......" Zhang Yongliang felt that he was under so much pressure, and the people who knew it had to pretend to be a white, and he didn't know what to do at this time.

"Don't make a fuss, if this case is messed up by us, the master and his old man can tear our skin when he comes back."

"So you have to work harder."

Li Xiangcai is not afraid of the master he has never met, and when the time comes, it will be a big deal to pat his ass and leave.

"Well, let's confirm the time of the deceased's death first!"

"How do you know for sure?"

"More than 3 days after death, it is difficult for ordinary pathology to infer the exact time of death."

"What then?"

"I've heard the master say that there is a forensic entomology in the forensic medicine, which judges the time of death according to the stage of growth and development of insects on the corpse, and the death time can be inferred by using maggots to reach ten and a half days, or even several months. Can we judge the time of death of the deceased based on the maggots that grow on the deceased?" Although Zhang Yongliang is a forensic assistant, he still has some understanding of forensic knowledge under the influence of the forensic department.

"Then let's get started."

"You really don't know?" Zhang Yongliang looked at Li Xiang suspiciously.

"Let's start, when the master comes back, you won't have a chance to show it."

Li Xiang gave this spiritual guy an encouragement, which made him more convinced that Li Xiang was giving him a chance to perform, and suddenly said incoherently excitedly: "Okay... Okay, I'll go get the book."

He had only heard of forensic entomology, and he had seen this book when he was cleaning up the bookshelf for his master, and now when he thought of it, he immediately prepared to take the book over, combining theory with practice, so that he could learn it quickly.

After a while, Zhang Yongliang came over with the professional book.

"I found out that there are four stages of fly development. At room temperature, the development time of the egg stage generally lasts 1-2 days. The larvae of flies, commonly known as maggots, can be subdivided into three instar stages, which last for about 6-10 days. The pupal stage generally lasts from one week to more than ten days. Finally, the pupal feathers turn into adults."

"Different species of flies develop at different rates. Besides

Factors affecting the species and development rate of maggots on carcasses also include temperature, humidity, light, carcass, etc."

Zhang Yongliang turned to the common ones in the family Flyflies, which are commonly used to infer the time of death.

And the maggots on this corpse are of this breed.

According to the instructions in the book, Li Xiang collected the insects on the corpses, killed some of them with boiling water, and then stored them in ethanol for future analysis, while others were sent to the culture room by him to be cultured at the temperature of a simulated crime scene to further confirm their developmental stage.

Flies are predominantly found on the early and middle carcasses, and Coleoptera mostly occur in the middle and late stages. If the empty pupal shells of flies are found on the corpse, or Coleopteran insects such as Guogongjia and Dermatoidae, it means that the corpse has lasted for a long time.

Fortunately, their corpse belonged to the early and middle red-headed flies.

There are several stages of corpse decomposition:

Fresh period: generally lasts 1-3 days, prolongs with the decrease in temperature, there is no obvious change in appearance, flies appear and lay eggs in this period, and the corpses located outdoors in summer have adult eggs on them within a few hours.

Swelling period: Ranging from several days to dozens of days in a row, the corpse is swollen, the smell of decay is strong, and the eggs hatch into larvae, which will still attract a large number of adult flies, ants and beetles to gather on the corpse.

Decay period: ranging from several days to dozens of days in a row, highly decomposed, liquefied tissues, strong odor, a large number of maggots feeding on many cavities, exposed bones. Maggots accumulate and tumble, taking up most of the carcass, and the number of adult flies that come to lay eggs decreases, and pupae and pupal shells can emerge.

And the current state of this female corpse is already in the decay period.

Finally, there is the drying stage: only hair and bones remain, most of the insects are gone, and only a few ants and beetles remain.

Li Xiang and Zhang Yongliang were working on the corpse while comparing the books, and for a while, they actually entered the atmosphere of learning, unconsciously ignoring the unpleasant smell of the corpse, and the picture was a little beautiful for a while.

It's hard to look at.

"If we know that it takes 20 days for the red-headed fly larvae to develop into adults under field conditions, and the collected maggots emerge into adults after 10 days, we know that the maggots found at that time are 10 days old, and combined with the data on the length of the egg stage, we can infer when the adults lay eggs, which is when death may occur."

The two of them compared the books and operated them very rigorously and meticulously step by step.

"Yes, if it's winter, it's not enough to know when flies lay eggs, but also the time it takes for flies to find their carcasses. But outdoors in the summer, the average fly can quickly smell the smell of death and reach the corpse, which is negligible in less than an hour."

The two who work hard can't tell at all that one of them is a forensic assistant who doesn't know anything, and the other is a trainee forensic doctor who knows nine out of ten.

People who don't know really think that the two of them are forensic doctors.

After sampling all the insect species, Li Xiang and the others began to clean up the corpse of insects, and they had to start checking the height, age and cause of death of the corpse.

Height is easy to say, just a simple measurement.

Although the age check is complicated, there are still many ways to detect it, and this is not difficult for two students who work hard in the dissection room.

At this time, they are going to use the pubic symphysis to determine the age of the deceased.

First, on the deceased, a piece of pubic bone is removed.

They had to accurately identify the morphological features and then calculate the age of the deceased according to the corresponding formula, which was very accurate and only between two years old.

Of course, even if this method is used, they also find the identification method in the book, and compare it in detail according to the atlas in the book.

There were 9 reference points for the morphological characteristics of the pubic symphysis, which were the groove of the symphysis, the ossification tubercle, the lower end of the symphysis, the ventral bevel, the dorsal margin, the ventral margin, the source of the oblique plane, the morphology of the symphysis and the bone quality of the symphysis.

The characteristics presented by these reference points are closely related to the change of human age.

Li Xianghe

Zhang Yongliang scored the morphological characteristics of the pubic symphysis in the book according to the score table, and at the same time introduced the corresponding score into the formula input calculation: Y=+X1+X2+... X9。

Y = inferred age, constant (male=16.45, female=15.32), X: grade score for each reference point.

In the end, I stumbled and pan and got Y = 32.6.

In the end, it is the turn of the cause of death to be determined...... Completely blinded.

Li thought that they looked at the scarred skin, almost a puddle of rotten flesh, and their poor knowledge reserve had no way to investigate the cause of her death.

Two weeks later, Li Xiang and Zhang Yongliang handed over an autopsy report that they thought they had done their best.

The deceased was a female, with a height of 160c, an age of about 32 years, and the time of death was 14 days. Cause of Death: Unknown, only one IUD was found in the body.

Subsequently, Li Xiang submitted the main quest in the system.

[Ding, 75% completion of the main quest, reward skill for the first completion of the task: forensic science, task rating: C level, reward skill experience +1000]

Suddenly, Li Xiang's brain was flooded with a huge amount of information, including basic medicine, clinical medicine, and related forensic science and technology, and forensic technology, and the breadth of knowledge far exceeded the previous copies.

Although it is only a basic level of knowledge, if Li Xiang wants to learn it by himself, he will not be able to finish it in three or five years.

Li Xiang digested it for a while before he alleviated the sequelae of this Daigo empowerment, and at this time he closed his eyes and slowly sorted out the knowledge that appeared in his mind, and verified it with the rotting corpse in the dungeon.

If he had to do it again, he would have done better this time.
