After they left, only the three of them were left at the scene. Yang Qiuchi said: "First of all, the reason for this woman's death was because of him."

"Nonsense! If you commit suicide, who can cut off your head and put it on the tree branch?" Song Yuner curled her lips.

"You are right," Yang Qiuchi said with a smile, "However, judging whether it is suicide, homicide or accident is the first step to solve the case. Only after confirming that homicide is determined, can the disabled be considered a crime and then the case is investigated."

Song Yuner didn't think so deeply about this. She nodded, her big eyes were bright, looking at Yang Qiuchi.

Yang Qiuchi continued: "After judging it as a killing, we must then judge the cause of death."

"Then you still have to judge? You must have been beheaded to death!" Song Yuner said confidently.

"Wrong!" Yang Qiuchi shook his head, "Zhao Qinglan's head was cut off after he died."

Song Yuner was about to show off her skills in front of her master, but she didn't expect that Yang Qiuchi would make the first judgment wrong. She was a little dissatisfied. She glanced at Wu Ruobing, blushed slightly and said, "How did you know that it was cut off after death? Who told you?"

"Tell me about Zhao Qinglan's body!" Yang Qiuchi smiled.

A chill rose from Song Yun'er's back spine and she said nervously: "Hey! Don't scare people, okay?"

Yang Qiuchi turned to look at Bai Ruobing. Seeing that although she was not afraid, she was looking at herself in confusion and said, "Don't be nervous, of course the dead will not speak, but if a problem can be found in the human body examination, isn't that equivalent to the dead telling us?"

"Hmph~~!" Song Yuner then breathed a sigh of relief, glaring at her almond eyes: "You must scare me to death, right?"

Yang Qiuchi laughed and said, "Why am I willing to scare you to death?" As soon as he said this, he immediately realized that something was wrong. He shouldn't have said these intimate words to Song Yuner in front of Li Ruobing. He looked at Li Ruobing. He saw that her expression was faint and had no special expression, but the fleeting loneliness in his eyes still did not pass through Yang Qiuchi's sharp gaze.

After hearing Yang Qiuchi's words, Song Yuner laughed and said shyly: "Hate it! Tell me quickly, how did the corpse tell you the old man?"

Yang Qiuchi found out that Wu Ruobing was unhappy, and he felt a little heavy. He carefully picked up the head wrapped in a sweat towel on the ground (he could only be carefully picked up because the corrupt giant's head was like a piece of tofu. If he tried too hard, the rotten muscles on his face would fall off), turned it over and exposed the cross section of his neck, and then said, "Please pay attention here."

Song Yuner and Feng Ruobing came forward and observed carefully, but they didn't see any significance.

Yang Qiuchi said: "The section of this cutting wound was not opened, and it was proved that the head was cut off after death."

"Duokai?" Song Yuner looked at Yang Qiuchi in confusion.

Yang Qiuchi realized that this word was a bit professional, so he explained it as popular as possible: "Simply put, it means curling and contracting, because if the wound is caused by life, the skin, muscles, muscles, legs, blood vessels, etc. have a certain degree of tension and contraction ability, it will cause the wound to tremble. The wound that is formed immediately after death will also have a certain degree of wound to tremble. This is caused by the supernatural reaction of the human body."

"Excessive reaction?" Song Yuner asked again.

Before the question was explained clearly, this question came out again. Yang Qiuchi looked at Bai Ruobing and saw that she looked at her curiously. He became interested and patiently explained: "After a person dies, some organs, tissues, and cells still have short-term vitality and can react to external stimuli, which is called hypergenesis reaction. It is precisely because of this phenomenon in organisms that organ transplantation can be achieved."

"Organ transplant?" Even Li Ruobing started asking.

Yang Qiuchi's head was already confused. He really wanted to slap himself in the face. In the Ming Dynasty, do you want to scare people? He didn't dare to explain anymore, for fear that the more he said it, he said hesitantly: "What I mean is that if the wound was cut when he was alive, the wound would shrink and curl. If he died for a while, he wouldn't."

When Xiao Ruobing and Song Yuner understood the characteristics of the wound, they quickly understood it.

Yang Qiuchi was afraid that they would continue to ask questions, so he quickly continued: "Please note that if this woman was cut off her head alive, the soft tissue on the cross-section of her neck would contract due to tremor, causing breakage and inconsistency and exposure of the cervical vertebrae. However, this situation obviously did not occur in the cross-section of this head. Therefore, her head should have been cut after death. The cross-sectional characteristics of her arms and feet are similar, which proves that it was cut after death."

Song Yuner seemed to understand and asked, "What's the matter with this?"

"Drive!"

"Yes, Duokai, besides that, is there any other way to prove whether the head was cut off before or after death?"

"There are some more," Yang Qiuchi explained patiently: "If the head is beheaded before death, during the process of cutting, the deceased still breathes because he is not dead. Therefore, the blood in the wound can be sucked into the lungs through the trachea, or swallowed into the stomach. Even if the head is cut off instantly, this phenomenon will occur due to the supernatural reaction. Therefore, as long as the lungs or stomach are cut open and the blood is stored, it can be proved that the head is cut during the lifetime."

When Yang Qiuchi talked about his home, he remembered that he could not dissect the ancient times, so he explained: "Of course, this is not easy to prove, so it is enough to prove it based on the fracture situation."

There are some other ways to prove whether it was a life or a post-mortem. Yang Qiuchi dared not say that because it involved more modern knowledge, such as checking for changes in the activity of the sci-fi enzyme, checking for vascular embolism in the lungs and brain, etc.

Song Yuner likes to show off because her master is by the side, so she stubbornly asked, "Then, you said she was not hacked to death, so how could she die?"

"It seems that she was probably strangled to death now." Yang Qiuchi pointed to the Adam's apple on the neck and on both sides of the neck that remained on the head, and said, "Have you noticed this? There are choking scars formed by fingers and nails. The scars formed subcutaneous blood spots, which proved to be a life-long injury."

Yang Qiuchi pointed to the crescent-shaped traces on both sides of the deceased's neck and said: "This is a nail indentation, which is a kind of epidermis, which is caused by the murderer's nail scratch. If you observe this leather-like class carefully with magnified eyes, you should find the rolling, the epidermis and scabs."

I almost said that I missed the mouth and said the magnifying glass. Yang Qiuchi is very careful now. On the one hand, I should avoid speaking modern words, and on the other hand, I should be as popular as possible. However, there are many things on forensic physical evidence that cannot be explained clearly in plain language. Then he said: "Did you notice that the oval subcutaneous blood class on both sides of the neck? This is the murderer's fingers pressed."

Speaking of which, Yang Qiuchi frowned and thought for a while, and explained: "The trace is very strange. Judging from the typical acupressure and nail injuries on both sides of the neck, it should be caused by one hand, and the deceased almost did not move. This means that when the deceased was strangled, the resistance was very small. This is strange. Zhao Qinglan's hand was very good at splitting the muscles and bones. Since she had martial arts, how could she not resist?"

Feng Ruobing frowned and said, "It is very likely that she has been broken by others."

Yang Qiuchi nodded: "Senior said it very reasonably. I have checked the joints of the corpse, but it was indeed twisted and dislocated, which confirmed the senior's speculation." Speaking of this, Yang Qiuchi remembered the Murong family in "The Legend of the Condor Heroes" that used his own way to cure his body. Zhao Qinglan subdued Yun Leng and the other three to learn from the advanced learning method, and now he is controlled by others and then strangled to death.

Song Yuner asked: "Who is this murderer? Have you found the clue?"

Yang Qiuchi smiled bitterly: "If solving a case is as simple as you said, you can immediately know who the criminal is, then who dares to commit a crime!"

"Then you always find some clues?" Although Song Yuner was a little afraid of the dead man, she didn't want to show weakness, so she said with a forced smile.

"Of course I found it, didn't I say it? Any crime will"

"It will leave traces, it depends on whether you can find it! Right?" Song Yuner rushed to say.

"Haha, yes." Yang Qiuchi pointed to the deceased's head and said, "Have you noticed the deceased's mouth and nose? I have checked that the deceased's jaw and chin, around the mouth and nose, lips and oral mucosa did not have any scars left by hand! What does this mean?"

Song Yuner and Xiao Ruobing looked at each other and shook their heads together. In terms of detection, what Xiao Ruobing, a peerless martial arts master knew was almost the same as Song Yuner's.

Yang Qiuchi continued: "As mentioned earlier, the murderer strangled Zhao Qinglan with one hand. What should the murderer's other hand be used for?"

Song Yuner rushed to say, "Cover your mouth! Or grab the other party's hand!" As soon as she finished speaking, Song Yuner felt something was wrong and hurriedly added, "The other party's hands and feet were twisted, so there is no need to grab them, so it should be used to cover her mouth!"

"Yes! It should usually be freed to cover the deceased's mouth, but the murderer did not!" Yang Qiuchi looked at the deceased's mouth and nose carefully and said, "There are two reasons. First, this is a primeval forest, and there is no one to hear it even if he screams at the death. However, since the murderer has a free hand, he is still idle anyway, and he will unconsciously cover the other person's mouth just in case, so the first possibility is relatively small; second, the murderer likes to hear the deceased scream!"
