Since he wanted to see if it was strangulation, Xu Chu naturally had to start with the severed neck. Due to the infection and decay of the wound, when she examined it, she only deduced the murder weapon that cut off the head, but found no useful traces on the surface.

"Generally speaking, the face will be swollen and cyanotic after suffocation. Because of the compression of the neck, the jugular vein is compressed, and the carotid artery and push pulse pressure are not closed, and the blood can only flow to the head, but not to the heart, which naturally causes blood depression in the head and swelling of the face. At the same time, it is very likely to cause bruising of the face, cyanosis of the lips and nails. In most cases, the cause of death can be inferred from the causes of strangulation, strangulation, and atypical hanging. As for some of the corpses, they were pale, just like the state of the young lady in the case in Cangyan County, it was because she was strangled from the front, which interrupted the blood flow in the blood vessels. Normal death or sudden death, although there is also suffocation, but there is no swelling. Xu Chu used some terms that were difficult for the ancients to understand into the vernacular, and then said regretfully, "It's just that this corpse has no head, and there is corruption, so many things are difficult to determine." ”

"At the beginning of the examination of the neck scars, the condition of the face, is it possible that there is no other way?" For the autopsy, Xiao Qinglang is not a person in the industry, he just knows a little bit about handling cases all year round. What's more, he does know very little about Xu Chu's experience and autopsy methods. So, at this time, I couldn't help but ask.

Xu Chu glanced at him, and when he saw his serious expression, he knew that this person did not mean to make things difficult. Immediately smiled bitterly, "Naturally, there are, for corpses that are highly decomposed and cannot be dissected, you can look for the hyoid bone, thyroid bone, and even the rose tooth caused by pulp hemorrhage to determine whether the deceased died of suffocation caused by external force." It's a pity that these key points were all cut off by the murderer. ”

In fact, it is extremely difficult to detect the symbol of suffocation in highly decomposed corpses, and the only way to determine the cause of death can be determined through these conditions and the unique symptoms of conjunctival hemorrhage in the eyes and faces. However, now the murderer didn't give them a chance at all.

"Now I can only pray that the deceased's bronchi will have some foreign bodies...... "The so-called bronchi is a branch of the trachea, which is divided into two branches, left and right.

Among them, the right main bronchus is thicker and shorter, and the direction is slightly straighter than the left bronchus, so most of the foreign bodies that fall into the transtubes enter the right side. In previous lives, it was common for people to have children who had difficulty breathing due to foreign body inhalation, and most of them were caused by this.

What Xu Chu wants now is that foreign body. She guessed that if the deceased really died of suffocation, then whether she covered her mouth and nose and died or was strangled to death, she would instinctively increase her breathing and want to live in an emergency, then it was very likely that something would be inhaled into her trachea.

As she lifted the knife and fell, the skin on her neck was sliced open with a thud, revealing the changes inside. Obviously, the small amount of blood left in the blood vessels had also turned into a turquoise chaotic oily liquid. As she moved, the liquid slowly flowed away.

The changes in the corpse are almost the same as the four seasons recorded in the book, the so-called five days of the cold day, such as the hot day, and the half moon such as the hot three or four days. Therefore, at this time, except for the absence of maggots, the corpse has already peeled off the skin from the neck like a corpse that has been placed for three or five days in the middle of summer.

Therefore, if she wants to clearly show the changes in the period to everyone, she must peel off the skin. The subtle rustling sound, coupled with Xu Chu's half-condensed and gloomy face, instantly made the cool air rise from the soles of everyone's feet.

She did not stop moving her hands, and said solemnly: "There is bleeding under the skin, the blood is clearly shaded, and the muscles are obviously damaged, which is a typical symptom of hanging." After a brief explanation, she calmly fixed the slippery vein with tweezers, and then carefully peeled off the ulcerated muscle.

At this time, who can say that she is just a weak woman, obviously with superb swordsmanship, and extremely bold.

After inspecting the subcutaneous condition, Xu Chufu aimed the blade at the trachea again. If you just look at her movements, it is pleasing to the eye, not to mention that in such a gloomy environment, a delicate woman should probably make people's hearts rise some tenderness. It's a pity that as long as the eye touches the knife and carrion under her hand, that little bit of praise becomes an unwarranted disgust.

Xiao Qinglang was not in a hurry to record at this time, his eyes followed Xu Chu's movements, and finally cruised to her cheeks. Half of the white little face is silent, only the dark eyes burst with persistence and seriousness, bright and unconsciously indulged in it.

Compared with the miserable white face supported by others, he only watched quietly, as if observing, but because of the smile on the corner of his mouth, it was a little weird and weird.

"What is this?" Xu Chu dissected the right bronchus of the corpse and bent down to look at it carefully for a moment, and just when a few more officials retched due to the tumbling in their stomachs, she also used tweezers to carefully pinch out a somewhat rotten mass from the wall of her trachea.

Because she had only checked the viscera before, and wanted to find some clues from the corpse's stomach, she made sure that the viscera were not damaged and that the stomach was difficult to examine in detail, so she sutured them up. Now I open the trachea, but I didn't expect it to be a real gain.

"Auntie, I'm bothering to find a white square scarf and spread it aside." Xu Chu cautiously pinched the tweezers.

When Aunt Chu heard this, she hurriedly took a small piece of folded white cloth from the toolbox and spread it out. It was at this time that she discovered that Xu Chu's toolbox was very different from the one she had seen in most of the hands of the craftsmen.

The three-tiered drawer, in addition to the tools, also has a stack of folding boxes of white cloth and oiled paper. She looked at it, the inconspicuous square box, was it the container that Xu Chu used to hold the gastric juice and the mucus in the abdomen?

At this time, where did she still think of the suspicion and contempt for Xu Chu just now? As if subconsciously, without Xiao Qinglang's signal, she was all taken by the little woman's concentration and eagerness when looking at the corpse.

Xu Chu placed the unidentified object on top of a clean white cloth and carefully followed its own veins to restore its original form. A moment later, the thing had a vague shape, but she couldn't tell what it was.

Before the rotting disgusting filth, only Xu Chuken looked closely, but the thing had been corroded, and the shape was a little unclear. However, after she wiped it slightly with a plain cloth glove, the spread object slowly unfolded into a straight line. And on the plain cloth gloves, there are also a few threads that are not obvious.

She looked at Xiao Qinglang and Zhang Youwei, and wondered, "It seems to be something like a thin thread?" Childe, have you ever seen it? ”

"It's silver thread and silk thread." Xiao Qinglang, who had been frowning and silent, suddenly spoke, and then moved his cuffs slightly, motioning for her to look, "It's the silver thread on the sleeve, maybe it's a certain pattern, or it's just a silver thread that is clumped together when swallowing." ”

As soon as these words came out, Xu Chu and Zhang Youwei looked enlightened. But if it is really a silver thread, how can it enter the mouth of the deceased and then draw into the trachea?

"Generally speaking, there are only two possibilities. First, the deceased desperately bit the murderer's arm, inadvertently biting off the silk threads and silver ornaments on his sleeves, and then died. Or in an embroidery workshop or something, someone took his life. Xu Chu's mind moved slightly, there was no trace of struggle on the deceased's body, but there were symptoms of malnutrition, which showed that her physical condition at that time should not be good. In the embroidery workshop, if you want to cut off the head, and then transfer the body to Liu Zhen's carriage under the cover of people's eyes, I am afraid it is not easy. "Bandits robbed, will they wear such a grand dress?"

Xiao Qinglang did not question her speculation, and nodded: "What the groom said in the dossier is that three bandit men are blocking the road, dressed in coarse cloth clothes, and their words are vicious, which is terrifying. Before he passed out, no one had ever been seen dressed in splendid clothes. If there is, I am afraid that it is only possible for Mrs. Liu Zhen of the Liu family in the carriage. ”

He gradually had a new speculation about the case in his heart, squinted at Zhang Youwei, and said slowly: "My lord, I think there should be no majority of people in this county who can use silver silk and silk thread to make dark lines or decorations on their sleeves." In addition, adults can secretly check the county's excellent embroidery girl, check the origin of the clothes, I think if you have used silver silk to make clothes, the embroidery girl should not be easy to forget. ”

In fact, it is not said that it is in the small Yunan County, that is, in the state city, there are not many people who can use silver and gold threads to accompany the silk that is warm in winter and cool in summer. Most of them will be owned by the families of meritorious officials and eunuchs, and there are also a few wealthy businessmen who have the opportunity to get some when they come and go to make a living. But no matter what the case is, it is impossible for ordinary people to wear it anyway.

It is precisely because he knows this in his heart that he says so.

"Now in addition to the murderer, there is another person who needs to be found as soon as possible." Xiao Qinglang saw that Xu Chu had begun to stitch up the corpse, and looked at Zhang Youwei solemnly after a moment of contemplation, "If the deceased is not Liu Zhen's, then where is the real Liu Zhen's?" And where is the kidnapped maidservant beside her? ”

"Perhaps, it was the maidservant next to her who died?" Xu Chu guessed thoughtfully.

"Impossible, the maidservant Xing'er who followed her that day has no birthmark on her body, and her height is not matched." Zhang Youwei shook his head, he also had such suspicions at that time, but after careful inspection, he found that this was not the case.

Anyway, today's autopsy is another new clue.

Xu Chu disposed of the corpse, took off the gloves and mask and made another place, and then said: "Now it can be seen that the deceased is not Liu Zhen's but someone else, and the corpse can be moved into Liu Zhen's carriage unknowingly. In addition, the head of the deceased was cut off by a firewood knife, which should have been used daily, and it was known that there were thatch roots and firewood chips on it. In addition, the deceased had bitten the arm of the real murderer before his death, or the murderer's arm was injured, and at the last time, a slightly luxurious dress was torn and the cuffs were missing the decoration of silver filigree. ”
