"There is a term in crime economics called 'crime cost', generally this cost is divided into three aspects, one is the economic cost, that is, whether the investment and benefit of the crime are matched, for example, it is impossible for any normal person to spend 1 million to rob something worth 990,000. The second is the time and opportunity cost, that is, the time and energy you need to carry out the criminal act, and if it is used to carry out a legitimate activity, will the benefits be higher than the gains from the crime? The third is the cost of punishment; if you are caught, how much will the punishment be borne for the criminal act? How much is the economic loss? These are the 'criminal costs'. Losing a job may be a temporary financial hardship, but killing someone ruins a whole life, and anyone will count it. So like you and that Xiaozhi person, it's unlikely that our police will include you in the investigation, understand?"

As soon as Li Xian's theory came out, not to mention Dang Hui, even Du Lin was impressed by this guy who usually hangs two waves, and it seems that he also has some theoretical skills.

"Okay, okay, Xiaohui, don't interrupt, let's analyze the blood sample. Du Lin stretched out his hand to Li Xian, and Li Xian took out a small thermostatic sealed box from his backpack and handed it to Du Lin.

"You a priori, I went out to call my colleague to tell me the identity of the deceased, and I took this resume?"

Durin waved his hand, signaling that it didn't matter, everyone was gone, why did he keep his resume?

Du Lin asked Dang Hui to wait outside the laboratory door, entered the laboratory by himself, opened the sealed box, took out a tube of blood from it, divided a small half and put it into the instrument to make a appearance, and then poured most of it into his mouth......

With a mouthful of blood, Duhrin came to the conclusion that there were no drugs in the blood of the deceased, let alone drugs that caused stuns and hallucinations, and it could be said that it was very pure, and the deceased still had a little cold before his death, but it was not serious, and there was a very important point, the deceased was pregnant! The pregnancy period was about six weeks!

As mentioned earlier, Doolin can determine the physical condition of the person through the blood, but forgot to mention another point, if the blood is fresh enough, Doolin can even see some of the things that the person has experienced recently, this is a new ability that has only appeared in the last hundred years, Doolin calls it "illusion", the fresher the blood, the clearer the illusion. If you drink the blood of a living person directly, you can even clearly know some memory fragments of the last 24 hours of this person, but if the blood leaves the blood vessel for more than 24 hours, then this illusion will not appear again.

For example, in the case of child abduction and trafficking in the first chapter, it was actually because Durin saw a vision from the baby's blood and found that the baby's parents were not the two people who sent the baby to the doctor at all, so he dared to determine that this was a pair of human traffickers.

From Luo Baiyao's illusion, Du Lin saw a departing back, because the surrounding environment was very dark, so it was a little difficult to see clearly, and then, the face of a young man appeared from the other direction...... The illusion didn't last long, but strangely, the first half of the illusion was normal, but the second half, after the young man appeared, the whole illusion looked very unreal, not only ghosting, but also some strange colored halos, which Durin had never encountered.

Recalling the young man who had just appeared in the vision, Durin felt a little familiar, and always felt that he had seen this man somewhere, but he was very unsure, and he was not even sure if this man had appeared in his memory.

With a long exhalation, Durin pulled out his chair and typed out an analysis report in front of the computer, of course, the data in it was not measured by the instrument, but "tasted" by Durin himself.

"Xiaohui, make a copy of this report for archiving, and give the original to Brother Li. ”

"Okay. Dang Hui read the report while walking to the photocopier, "Doctor Du, there are no drug ingredients in the blood of the deceased?"

"Hmm. ”

"Then how could she let the murderer stab her with a knife? Even if she fell asleep, she should have woken up in pain and struggled for a while?"

"yes, I'm curious about that, too. Dang Hui's words made Du Lin suddenly flash a thought in his mind, and Du Lin wanted to grasp this idea but couldn't grasp it.

"The results are out?" Li Xian came in from outside, just as Dang Hui finished copying the report, he took the original and looked directly at the conclusion, "No medicine? cold? Are you pregnant?"

"Yes, the instrument does not lie, the deceased's blood was clean and did not contain any drug ingredients, indicating that she had not ingested any drugs in recent days. The deceased was studying medicine, and she knew that she was pregnant, and she also knew that taking medicine indiscriminately during pregnancy would affect the fetus, so she deliberately did not take medicine when she had a cold. ”

"Well, most likely, I took the report first, and if there is anything needed, I will come back to you. ”

"You must come to me, this deceased was supposed to come to me for an interview today, and now that she is dead, I feel that I have an obligation to help her, and besides, I think I can help you get justice for her. ”

"Why?"

"Intuition!"

There was nothing major on this day, and the hemolysis clinic was still the same as before, with no patients. After all, it is still a newly opened clinic, and the doctor is so young, even if it has been recognized by the Public Security Bureau, but not many people know about it, Du Lin asked Dang Hui to find someone to make a white steel brand of "Zhonghu City Public Security Bureau Special Testing Center", and planned to hang it at the door, hoping to increase its popularity.

At about 4 o'clock in the afternoon, Li Xian called Du Lin to go to the criminal police team, saying that he needed his help in something, and asked him to participate in the case analysis meeting as a "special expert".

Du Lin asked Dang Hui to go home from work early, Dang Hui said that it was nothing to do anyway and wanted to go with Du Lin, Du Lin thought about it and agreed.

The criminal police team is in the compound of the Zhonghu City Public Security Bureau, which is an independent three-story building behind the office building, Li Xian sent a small policeman to wait at the gate of the public security bureau, because he didn't know that Dang Hui was coming in advance, so he only prepared a temporary identity card for Du Lin, and the policeman explained to the doorman before putting Dang Hui in.

"Yo, Dr. Du's grade has gone up, and he has brought the little secretary with him. As soon as Li Xian saw Du Lin, he would show his true face without a proper shape.

"This is my assistant, Dang Hui. ”

Girls naturally have a sense of admiration for the police, and when they saw so many policemen at once, Dang Hui was a little excited, "Hello everyone, my name is Dang Hui, and I am Dr. Dulin's assistant, please take care of me!"

The old criminal policemen in the criminal police team were okay, and several criminal policemen who were not married were more excited than Dang Hui, and they gave up their seats and poured water, but they put Du Lin aside.

"Do you regret bringing her here?" Li Xian poured a cup of hot water for Du Lin and pulled a chair for him, "Or I'm still good to you." ”

"Good to me? You want to get news about Danghui from me, right?" Du Lin looked at Li Xian seriously, and looked at Li Xian with a straight hair in his heart.

"How can you speculate on me like this?" Li Xian hurriedly showed that he was open-minded, "However, I really have something to ask you." ”

"What?" Du Lin took a sip of water and glanced at Li Xian.

"That...... Does Xiaohui have a boyfriend?"

"Get out!"
