Shaking his head, Xia Mu threw away the useless superfluous feelings in his heart, after all, now is not the time to be sentimental, and it is not too late to put it when he catches the criminal.

Xia Mu threw all his mind into the corpse, and sure enough, the same mechanical suffocation died. The same posthumous sewing of corpses, the same without extra traces of struggle, without any wounds.

Sure enough, the perfect crime as always.

If you have to look for the difference between this corpse and the corpse, there is only one, and the suture part is different. However, this is not the murderer's wrong operation, but only because the internal organs taken away are different.

"How? Could a corpse be the work of a single person? ”

Xia Mu was taken aback by this sudden speech, and unconsciously took a few steps back.

Seeing this, Gu Cheng scratched his head embarrassedly, stirring his messy hair even more invisible. "I, I knocked on the door just now and no one answered, I thought this was the meaning of letting me in directly, but I didn't expect to scare you, I'm sorry, I apologize to you."

"Leng Nian'er!"

"What?"

"I said you can call me Leng Nian'er directly!" It was the first time Xia Mu had seen Gu Cheng look so cramped and uneasy, and he suddenly felt a little cute.

"Huh?" Gu Cheng was stupid, he thought that this beautiful forensic doctor was a cold species that was not easy to communicate, but he didn't expect Xia Mu to be so friendly, "Oh, good, Leng Nian'er." But isn't this a bit out of sight, how about calling Nian'er? ”

Xia Mu glanced at Gu Cheng, "Whatever you want!" ”

After saying that, he ended this absurd conversation and quickly got to the point, and even his expression became serious.

"There's good news and bad news, which one do you want to hear first?"

"Good news!" Gu Cheng paused for a few seconds, and reluctantly began to choose, hoping that the good news could withstand the uneasiness caused by the bad news.

"The good news is that the two bodies are not exactly the same."

Gu Cheng immediately breathed a sigh of relief, it's so good that it's different, it's different.

"But the bad news is that the difference comes from the part where the internal organs were extracted, and it's almost exactly the same everywhere else."

Without giving Gu Cheng a respite, Xia Mu continued, "The deceased is a woman, about 27 years old, and the time of death is no more than 24 hours, and it is expected to be between one and two o'clock in the morning today. The deceased's internal organs were removed from the lungs, and a large amount of alcohol residue and drug components were found from the residue in her stomach. The deceased had eaten seafood before his death, so it should not be a cheap place. Because it contains an expensive seafood spice. ”

"I have also tested the ingredients of the drug, and although the main ingredient is the same as that of sleeping pills, the dosage of other ingredients is different. As far as I know, there is no such dosage of drugs on the market at all, and it should be the murderer's own prescription. ”

"Why isn't it on the market?" This confuses Gu Cheng, it is called a medicine but it is not circulated in the market, why is this?

"This dose of the drug reduces almost all kinds of auxiliary ingredients and increases the proportion of sleeping tranquilizers. The advantage is that the goal can be achieved quickly, and the victim can be killed with one blow. As long as 20 seconds and as short as 10 seconds, it can quickly hit an adult, and the gram count is only 0.1 grams. ”

"This shows that the drug is easy to use and carry, and it can even leave no traces. The disadvantage is that the dosage is not easy to control, and once the dosage is exceeded, it is expected to lead to the death of the user. But if it's for killing, then this disadvantage doesn't exist. ”

"And, if I'm not mistaken. Twenty years ago, a medical experiment proposed this proportioning method, but it was also canceled in the mouse experiment stage because of its side effects. However, the reappearance of this ratio made me more determined in my judgment. ”

"The murderer is not just a person who is engaged in medical research and has experience in clinical medicine. Moreover, he has a systematic medical background, and even his professional ability is definitely not lower than that of any medical doctor. ”

Gu Cheng was even more shocked when he heard this, "Doctor of Medicine, isn't this a joke?" ”

Xia Mu ignored his reaction, "Not only that, but his murderous methods are evolving. Judging by the corpse, the calmness is unchanged from beginning to end. However, the direction and angle of the knife edge, the accuracy of the knife used by this corpse is much higher than that found before. ”

"Not only is the angle more in line with the part of the viscera taken, but the distance of the cut and the direction of the stitch allow him to move more quickly."

"The murderer whose actions will escalate, there will definitely be the next victim." Xia Mu said unusually calmly, but found that Gu Cheng had already abandoned that kind of ruffian image, and he was serious.

Finally, he finally showed his face......

Why do you say finally, this has to start with the first time Xia Mu met Gu Cheng. Although Gu Cheng behaved very seriously throughout the first meeting, he was a little immodest in his words.

And the key is that his eyes are serious, but they don't seem to start from the bottom of his heart. It's as if it's just skin making expressions, and there are no waves in my heart. But just now, he exuded an aura that could be trusted, and he was casually removed from his body. A sense of urgency of the task is on the horizon.

"I'm going to report to the director, it's hard work!" Turn around without a hint of muddy.

No one knew what Gu Cheng and the director were discussing, anyway, half an hour later, the task force on serial killers was officially established.

Forensic Department: Zuo Nao, Xu Zhixue, the investigation team is headed by Gu Cheng, and Wen Jianyuan, Wei Junyi, Bian Gaolang, and Ke Xiangchen are team members. Feng Ping served as the leader of the logistics team, and Xia Mu himself became a forensic member of the serious crime team. ”

The members of the task force are not the same as Xia Mu's memory, I don't know if it's because of the different time of judging the serial murder case, the serious crime team that was supposed to be composed of ordinary police officers has all become the city's elite this time. Each name in it represents the backbone of each game.

"Okay, so I don't need to introduce myself, so I'll tell you a little bit from left to right. On the left are Zuo Nao, members of the Forensic Department, Xu Zhixue, and all the evidence found can trouble them casually. Next to him is the investigation team, which is Wen Jianyuan, Wei Junyi, Bian Gaolang, and Ke Xiangchen, who are responsible for investigating with me. Feng Ping is the leader of the logistics team, and the last beautiful woman with a raw face is Leng Nian'er, the forensic doctor of this case. ”

"Let the forensic doctor introduce the specific situation to us first, Nian'er, it's up to you."

Everyone stared at Xia Mu with curiosity, there are definitely few people who can make the Cold Face King call him so affectionately. What's more, it's such a beautiful woman, wouldn't it be the peach blossoms of the cold noodle king.
