"Did you notice that teapot? There is no quilt in the bedroom, how can there be a teapot? Ye Yinuo asked.

Dong Bingning said: "The teapot is naturally not used for drinking water, it must be used to water rosemary." ”

"If I'm not mistaken, it's dry inside, and there's no water."

Dong Bingning unscrewed the lid of the pot and looked at it, it was indeed very dry inside, she shrugged her shoulders and said, "Then what?" ”

"You sniff carefully, if the spout of the teapot stinks." Ye Yinuo said.

Dong Bingning put the spout in front of his nose and sniffed it, his face changed and he looked at Ye Yinuo and said, "Sure enough, there is a slight smell, how do you know?" Do you have a dog's nose? ”

Ye Yinuo said directly without hesitation: "Because this teapot was once stuffed into Song Ke'er's backyard, up to the position of the rectum. ”

Dong Bingning was stunned after listening, subconsciously put down the teapot, and his eyes became a little angry, Ye Yinuo smiled, quickly changed the topic, and said: "If my calculation is not omitted, Song Keer should have committed suicide." ”

"Suicide?" Dong Bingning's attitude really changed, she looked at Ye Yinuo with a little stunned and said, "The cause of her death was sexual asphyxiation, why did it become suicide again?" ”

"There are many kinds of sexual asphyxia, the most common of which is self-yin asphyxia, which refers to the use of hanging, strangulation and other ways to control breathing by a person with sexual psychology and sexual behavior alone, causing a lack of oxygen in the brain, stimulating and enhancing his xing desire to reach orgasm." Ye Yinuo explained.

Dong Bingning professionally took out a pen and paper and began to record, his eyes looked at Ye Yinuo from time to time, but he didn't continue, looking up at the ceiling, thinking about some questions.

"What are you thinking?" Dong Bingning asked suspiciously.

"I'm wondering if Song Ke'er is trying to frame me, or is it trying to frame the person who entered her room before she dies?"

"Song Ke'er wants to frame you?" Dong Bingning asked in surprise.

Ye Yinuo said: "Even if she didn't want to frame me, she wanted to involve me in this case, or was coerced, but the person is dead, and I can't ask her personally." ”

"So, you can only investigate the case, how do you determine that the time of death is after eleven o'clock, and the results of the autopsy are obviously eight to nine o'clock." Dong Bingning looked at Ye Yinuo with some expectation.

Ye Yinuo said lightly: "You also said before that the specific time of death should be calculated according to the temperature and relative humidity of the scene, right?" ”

"Yes, and then."

"If the temperature in the bedroom is low when Song Ke'er dies, then it will speed up the degree of corpse morture and slow down the appearance of corpse spots, right?"

"That's right, but the temperature difference needs to be more than ten degrees, you mean, Song Ke'er turned on the air conditioner when he died?" Dong Bingning asked suspiciously, turning her head to look at the air conditioner hanging on the wall.

"No, the outside unit of the air conditioner is outside, if she turns on the air conditioner, I should be able to hear the sound last night, but there is no sound, Qingyu City has a pleasant climate, there is no need for heating in winter, and the air conditioning in this apartment has no heating effect, it should not have been turned on for at least half a year, you can look at the dust on the fan blades of the air conditioner, it should be very thick." Ye Yinuo analyzed.

Dong Bingning pulled a chair from the living room, stood up, opened the fan and blew it kissingly, the dust suddenly flew up, and she coughed directly.

"Ahem...... It's true that the air conditioner hasn't been turned on for a long time, so what does she rely on to cool down? Dong Bingning jumped down and looked at Ye Yinuo and continued.

"It should be a physical cooling through some kind of substance." Ye Yinuo said and turned around and walked towards the open kitchen in the living room.

Dong Bingning hurriedly walked over and said, "Physical cooling? Ice? It couldn't have been ice, the room was dry, there were no water stains, and the relative humidity of the air was normal when the body was found in the morning. ”

"Abnormal, right? The humidity should be lower than outside, so give me a pair of gloves. Ye Yinuo walked out of the bedroom and stopped in front of the kitchen cabinet.

Dong Bingning took out a pair of gloves and asked, "What are you looking for?" I asked what the humidity was when the technical team entered the site yesterday. ”

Ye Yinuo put on gloves, Dong Bingning started to call, the cabinets were opened by me one by one, and finally two thermos flasks were found in the innermost cabinet.

And Dong Bingning just finished the phone, she said directly: "You are right, when the technical team inspected the scene in the morning, the relative humidity of the bedroom was 40%, and the relative humidity of the living room and outside was 50%, which was a little lower, but this ruled out the possibility of ice." ”

Seeing Ye Yinuo looking at the two thermoses, Dong Bingning asked suspiciously, "Is there anything wrong with this thermos?" ”

"This apartment has a 24-hour hot water supply, and the water dispenser in the living room is also on, and there is boiling water at any time, so it stands to reason that the thermos flask is not needed." Ye Yinuo said directly.

"What's strange about this, it's normal to have two thermos flasks at home."

"The point is that this thermos is new and there is no dust on it, which is not normal." Ye Yinuo took a flashlight and took a photo.

Dong Bingning nodded as if he didn't understand and said, "Well, that is, this thermos bottle was recently purchased?" ”

"You can check the surveillance, the last time she went home, it should have been no more than twenty-four hours before she died, and she should have these two thermos flasks in her hand." Ye Yinuo said.

Dong Bingning wrote a few more strokes, and then asked: "I haven't seen that monitoring yet, and the collective analysis of the case hasn't started yet, I still don't understand how she cooled down, and the thermos flask can still cool down?" Even with ice, the amount of ice in two thermos flasks can't lower the temperature in the bedroom by 10 degrees. ”

"Dry ice!" Ye Yinuo said and opened the lid on the outside of the thermos flask, revealing the plug that was not tightly stuffed on the bottle gall, he pinched the plug hard, and his expression was even more affirmative.

"Dry ice!!" Dong Bingning instantly understood, "If you use dry ice to cool down, then everything makes sense." ”

Ye Yinuo smiled and said, "Do you need me to explain anything?" ”

Dong Bingning rolled his eyes, and then said: "You still say it from the beginning, I haven't figured out your reasoning ideas, and everything is just your speculation, we need evidence to prove it." ”

Ye Yinuo walked towards the sofa and said, "Okay, then you listen carefully, I'll only say it once." ”

Dong Bingning sat upright, put the notebook on Bai Huahua's lap, and looked very pious.

"The content of my book is basically consistent with the time, place and method of death of the deceased, these are all plots that can be inferred, but there is one point, the red and black erotic underwear described in my book is impossible to deduce, because the previous plot has not been mentioned, so I suspect that the time of Song Keer's death is after I update the novel."

"Is it possible a coincidence?"

"Song Keer is a graphic model, and you have also seen that there are many sets of underwear in the wardrobe, and the possibility of a coincidence of a set of red and black just now exists, but the probability of wearing this coincidence when he dies is very low. With this as a starting point, I first set the time of her death after the publication of a new chapter of my novel using the inverted situational method. ”

"Well, go ahead." Dong Bingning nodded and said, quickly recording it.

"With this premise, then we can start from the reason for the deviation in the judgment of the time of death, the reason for the deviation is related to the degree of zombie, the time of the appearance of the corpse spot and the temperature of the rectum, in the zombie and corpse spot are determined by temperature and relative humidity, but these two factors do not affect the temperature of the rectum."

"I see, that spouted teapot! Affects the temperature of the rectum. Dong Bingning said.

Ye Yinuo nodded and continued: "Song Ke'er used dry ice to change the temperature and relative humidity, and then stuffed a teapot filled with dry ice into the backyard, so that the temperature of the rectum also decreased, these three factors combined, plus your forensic doctor Er Fat did not get the permission of her family to dissect, so it caused a misjudgment in the time of death." ”

"Well, how did you come up with dry ice?" Dong Bingning asked.

"There is a pot of rosemary in the bedroom and living room, the rosemary in the bedroom is greener, but the degree of tightness of the leaves seems a little sluggish, the flowers and leaves of rosemary have excellent antioxidant properties, and antioxidants and rosemary essential oil can be extracted from them, and it is precisely because of this that the commercial value of rosemary is very high, this antioxidant will produce a lot of green pigment when it encounters a high concentration of carbon dioxide environment, so the color of rosemary in the bedroom is greener, and at the same time, rosemary likes warm climates, The sudden drop in temperature will cause the rosemary flowers and leaves to wilt. Ye Yinuo explained patiently.
