"There was no fluid in the lungs of the deceased, not by drowning. It means that she was dragged into the bathtub after she died. There is a large amount of blood clots in the cerebellum. The fatal cause is most likely to be death from being hit in the cerebellum by a heavy object" Song Xiang threw the scalpel into the plate with a crisp sound, and at the same time, Zhao Yan's camera also made a final click.

"Is there anything else I can do to help?" Zhao Yan asked.

The human skin on the dissecting table was pale, and a little orange oozed from under the skin, which was not obvious under the shadow of the lamp, and Song Xiang's eyes were lowered: "Wait a minute, please continue." ”

She took off the bloodstained gloves on her hands, threw them into the medical waste bin next to her, and pulled out a new pair of gloves from the right pocket of her hazmat suit and put them on: "Please keep recording." ”

She pulled out the needle and reagent tube, gently broke a piece of skin on the deceased's heart, removed a piece of tissue, put it into a test tube, and walked to the instrument room next door.

"Maybe I guessed wrong before, you see, the deceased's skin began to turn yellow, the congestion of the cerebellum was not necessarily formed by a heavy blow, it seems that it may be a suffocating drug, but it has not been detected which drug it is" The fine sweat stains on Song Xiang's face climbed up to her forehead, the mist hazy the lenses, and she was a little panting, she took off her gloves and took off her glasses, and rubbed her eyebrows.

"Are you sure?" Zhao Yan asked.

Song Xiang twisted his thumb and pulled out the cloth of his glasses: "You go to the morgue first and wait for me." ”

"Okay." Zhao Yan checked the photos in the camera as he pushed open the door and walked out.

After Song Xiang dried his glasses, he gently pushed his thumb up, rested it on the bridge of his nose, took out a pair of white gloves from his pocket, and took away the skirt on the table.

There was not a single spot on the deceased's entire body, just yellowing, the color of an orange, and a little bit of color had just oozed from under the skin, and now it was almost spreading. Song Xiang walked over and saw Zhao Yan standing in place a little surprised, and asked in a daze. "Doctor Song, what's going on?"

As expected, Song Xiang lowered his eyelids, as he thought, as long as he was out of low-temperature storage, the toxins in the corpse would spread out. "I still have to do a test, can you push the deceased back to the second body cabinet first?"

Zhao Yan complied.

The drug test had to wait for two hours, and Zhao Yan sat at the door of the reagent room, with a pair of coconut butter in his mouth with his tongue. The scene that Song Xiang came out to see was a small bulge on both sides of Song Fu's cheeks, and there was a crystal of sugar juice on his lips, Zhao Yan pursed his lips slightly, and rolled the sugar juice back, Song Xiang raised his eyebrows: "From here on, you are not allowed to eat." ”

"The test results are in?" Zhao Yan bit the sugar in his mouth in two bites and swallowed it.

"The results came out, the deceased contained a large amount of modified orange juice under the skin, and there were no harmful substances in the stomach and internal organs." Song Xiang handed over the test report in his hand.

“？” Zhao Yan immediately raised his curious little ears: "Does orange juice make people like this?" ”

"Of course not with regular orange juice. But orange juice with added ingredients is different. Song Xiang pointed to the elemental synthesis data on it with his fingertips.

"Could it be that the orange juice has become a sperm?" Zhao Yan said half-jokingly.

Song Xiang smiled, then shook his head and said, "The orange juice under the skin of the deceased has a large amount of tannins. But an ordinary orange contains very little tannin, and if you want to make the whole body turn this color. That would have to make the deceased eat nearly 3 tons of oranges or orange juice in at least two hours. After a pause, he said, "This is almost impossible, and after testing, there are no oranges in the stomach, intestines, and digestive system of the deceased, so this possibility is directly ruled out." “

Zhao Yan touched his chin and didn't speak. He gently smoothed the candy wrapper in his hand and carefully put it in his pocket. "In other words, the perpetrator is at least familiar with chemical agents." Zhao Yan was thoughtful.

Song Xiang shook his head: "Not necessarily, maybe the perpetrator didn't know that the tube of reagent would allow the deceased to penetrate and spread from under the skin to the epidermis of the skin after death." ”

"Let's talk about why orange juice is fine." Song Xiang turned the page of the report and faced Zhao Yan: "Although denim is common, it takes a lot of effort to collect it. There's no way there's that much denim in orange juice, and it's just been overturned. Then there is only one possibility left, the deceased was directly injected with subcutaneous tannin chemical agents. H2S is added to ordinary tannins and injected into blood vessels. The fusion of tannins and H2S spreads, and the tannins float on the epidermis, causing skin discoloration. ”

"Although I haven't passed chemistry, I still know that H2S is a very powerful chemical drug, if the perpetrator just wants to kill Lucy Liu, why do you want to add denim to discolor your skin?" Zhao Yan was a little puzzled: "Isn't this an extra move?" ”

Song Xiang shook his head, saying that he didn't know, and spread his hands: "It doesn't have to be a semi-finished medicine." ”

"How?" Zhao Yan pricked up his ears.

"You know the black market." Song Xiang pushed his glasses: "I have two speculations. ”

"You say. Let's talk while walking, Hu Runqing urged. Zhao Yan took out his mobile phone and looked at it.

This is the fullest meeting room in Cloud City.

After the investigation and criminal investigation sat in a row, the time for this autopsy and testing was too hasty, Song Xiang could only directly use the camera memory card to link to the computer display, Zhao Yan's photography skills were not good, but it was clear enough, a piece of paper on the canvas was bloody, and the frozen organs and human tissues were presented, and the cub who had just interned was recording the minutes of the meeting, and as soon as he looked up, he began to vomit with the trash can. Song Xiang raised his eyebrows slightly, and first switched the screen to the text version of the report.

"The deceased, Lin Xuefang, female, 32 years old. After testing, the main causes of death were: respiratory tract occlusion caused by asphyxiation of chemical drugs and reagents, and death from lung failure. There were no obvious characteristic wounds, and there was a bruised wound on the back of the head near the neck, which was detected to have been caused 2-3 hours before death. "Song Xiang changed the picture." Time of death, five days ago. ”

"There are doubts." Hu Runqing knocked on the table.

Song Xiang looked at him: "Speak." ”

"Asphyxiation drug reagent name." Hu Runqing asked. "Was it a conventional or illegal drug, and was the deceased a drug allergy to death or a premeditated murder?"

Song Xiang switched to a photo showing the whole body of the deceased: "A new type of illegal drug, but my personal guess is that it should be a half-finished product." ”

"Semi-finished products?" The studious little beard made a second sound.

Song Xiang answered all questions: "Because the side effect of this medicine is that after the death of the deceased, the element of tannin will gradually appear, penetrating and spreading from under the skin to the epidermis. It can't be a finished product. ”

Xiao Hu nodded as if he didn't understand: "Then the deceased is the trial of the new drug?" ”

"That's one of the guesses." Song Xiang said: "The deceased may have been a victim of a trial of a new drug. ”

"There is also a possibility that the perpetrator deliberately killed people with the half-finished drugs that flowed out of the black market, but should not have been aware of the side effects after death." Song Xiang changed the canvas to a text report version, so as not to vomit too loudly among the interns in the back row.

"Because the deceased stayed for too long and did not do an autopsy in the first place, it is difficult for me to extract the exact composition of the medicine, and most of the elements have been dissolved by the human body."

Song Xiang turned off the computer. "I'll make a detailed report and send it to you later, I won't participate in the case meeting, and I still have to put the finishing touches on it and see if I can find third-party clues."

She put away the power cord, turned off the computer neatly, stuffed all the paper reports into the file bag, and then put the human tissue on the tray into a black canvas bag, and gently closed the door when she went out.

Zhao Yan chased out, grabbed a handful of candy from his pocket, and said in a deep voice, "Thank you." ”

In fact, this scene is a bit funny, Zhao Yan is tall, with a black jacket on his upper body, black canvas pants, a pair of low-cut Martin boots to tie the trousers into it, and his hair is a little short, he belongs to the category with relatively tough contours, and he doesn't look like a person who can take out a handful of fruit candy from his pocket.

Seeing that Song Xiang hadn't answered for a long time, Zhao Yan paused, grabbed a handful of milk candy from another pocket and handed it over: "Do you want to eat?" ”

Song Xiang smiled: "Then I'll take a pineapple-flavored one." ”

"Thank you."

Song Xiang is not the sweet kind when she laughs, she has a goose egg face, phoenix eyes and willow eyebrows, thin lips are slightly raised, there is a small red mole at the corner of her eye that is not obvious, and the small mole at the corner of her mouth is particularly obvious, and when she laughs, the corner of her mouth rises with the corner of her mouth, which is very vivid and flexible, and a little moving.

Zhao Yan looked at her back with a sneer, stuffed the remaining sugar into his pocket, and only left a pineapple-flavored fruit candy, peeled off the candy paper, threw it into his mouth, and licked it carefully.

It seems that I usually ignore this taste, otherwise why would it taste so sweet today.

Song Xiang went back to the underground morgue with his things, labeled them according to their positions and sorted them before going to the material room next door, and as soon as he sat down, his butt was next to the stool, and the mobile phone in his pocket buzzed and vibrate.

This time, there is a caller ID on the display screen - Gu Yu.

"Doctor Song, why doesn't it go to the toilet with orange?" Gu Yu asked a question mark in confusion.

Song Xiang: ???
