When Professor Ji Dongli saw Xu Zheng and asked about the knowledge of poisons, his good teacher side began to play a role, pulling Xu Zheng to talk about poisons, plus Xu Zheng himself has the skills of poison analysis given by the system, Professor Ji told him a lot of poison prescriptions synthesized by modern scientific and technological methods, and the two talked very happily.

The so-called thousand machine poisons in modern times, of course, are not those simple venoms extracted from plants, ores, animals, and insects in martial arts, but various chemical compounds, which are small in amount but not small in lethal dose.

Like ricin, 1 gram is enough to kill 3,600 people.

There are also some elements purified from minerals, such as chlorine and arsenic, mixed with some other compounds, the lethality rate is very high, the victim has basically no signs of poisoning, and this compound only has a surging almond smell, 40% of people do not smell this taste.

Most of the poisons studied by modern people are toxins that act on nerves, such as tetrodotoxin, which is an amino hydroquizoline-type compound, and a little bit of a needle tip can kill people.

The reason why Xu Zheng asked about this Qianji poison is also because of the eucalyptus that a large team is currently investigating, and he is not very clear about the specific process of the suspect's operation, but the current autopsy results of the deceased are a bit weird, and today I just took this opportunity to ask Professor Ji.

Ji Dongli raised his glasses, and his gray eyebrows wrinkled, "The eucalyptus you are talking about, Xiao Lu from your city bureau sent me information, and the specific situation has not yet been released on our side, are you going to work tomorrow?"

Then you should come to the Provincial Department of Clinical Medicine tomorrow and follow along. ”

Such a good learning opportunity Xu Zheng definitely wants to go, but, "I don't have to go tomorrow, this eucalyptus is currently in charge of the first team, and our second team has just been on a business trip for more than ten days, and this work is estimated to be coming." Can the teacher send me a copy of the test materials, and I won't tell you, I'm still quite curious about this eucalyptus. ”

Ji Dongli knew that the criminal investigation was busy, and he didn't care very much about whether Xu Zheng could come, "That's okay, but if you're really interested, let's go to the forensic department of your city bureau to see the body of the deceased in person, as forensic doctors, the first step of the investigation of the surface of the corpse can't be avoided." ”

Xu Zheng nodded hurriedly, although he did not have a formal forensic qualification certificate, nor was he a criminal investigator in charge of this eucalyptus, but with his current ability and the relationship between Forensic Doctor Lu, it was still okay to observe the process of their autopsy.

"You two stop talking, come out for dinner." Mrs. Ji saw that the two of them had been chatting for more than half an hour, and she didn't make a good meal and serve it to the table, so she called them out to eat.

I have to say that the old lady is also a particular person, the meals are all the tastes of Changming people, and she also prepared four dishes and one soup for three people, the soup is duck soup, and when you smell the taste, you can feel that this heat should be boiled in a casserole for more than an hour.

Seeing Xu Zheng and them coming out, the old lady smiled and said: "Xiao Xu, go wash your hands and prepare for dinner, you are still a guest at our house for the first time, I don't know what your taste is, if it is delicious, you should eat more, otherwise we will not be able to finish eating." ”

"Master's wife's food looks like it's the craftsmanship of the old people, especially the old duck soup, you know it's delicious when you smell it."

Ji Dongli raised his hand, "The bathroom is there, hurry up, I have to check your homework for a while after eating." ”

When Xu Zheng came out after washing his hands, the old lady had already specially brought out a bowl of duck soup for him, "Come, let's drink two sips of appetizers first, let's grow up to be bright, if you don't eat some duck meat and drink some duck soup a day, you won't be considered eating." ”

When he got closer, Xu Zheng took a closer look at the old lady and said that it was the old lady, according to Ji Dongli's age of 61 years old, the old lady was estimated to be about the same, and the reason why the two of them looked old was mainly because their hair was not dyed.

If Andy Lau appeared on the screen with white hair, he wouldn't look like a 52-year-old at the age of 62.

"I heard that your grandmother is alive, she is expensive this year?" Mrs. Ji chatted with Xu Zheng during the meal.

Xu Zheng hurriedly swallowed a mouthful of saltwater duck, "My grandma is 67 years old this year, does she have to be ten years older than you?" ”

"Huh... I, how can I be so young, I am also 65 years old this year, I am 4 years older than your teacher, the years are not forgiving, when I was young, I am much older than him. The old lady didn't know why, she liked Xu Zheng very much when she saw it, basically she didn't eat much, she was busy adding vegetables to Xu Zheng.

"Ahem... What nonsense, what are you not old, can I still dislike you for being old? Ji Dongli pretended to cough twice, reminded his wife to wake up, and changed the topic.

It's a pity that Mrs. Ji didn't think about his words, "Xiao Xu, no, I'll call you Xiaozheng, speaking of which, my granddaughter should be four years younger than you, and she is a sophomore or junior this year, just in our medical department, in the heart, doctors and forensic doctors happen to have a common topic, and you young people have time to talk..."

"Ahem... Don't be busy, Xiao Zheng is going to get married in October this year, and you're too late. Ji Dongli looked at Xu Zheng, and an idea appeared in his heart, how good it would be if this was his grandson-in-law.

However, adults can naturally control their thoughts, and so is Mrs. Ji, disappointed, she asked curiously, "Xiaozheng, aren't you only 24 years old?" Isn't this too early to get married? ”

"I am..."Xu Zheng was about to explain, but Professor Ji stopped him with a smile and asked him to eat first, "Xu Zheng's girlfriend is his neighbor, a childhood sweetheart, four or five years older than him, I just wanted to tell you this." ”

"Four or five years old, okay, the third female college student holds the gold brick, in October, it's the National Day to get married, right?" Old Lady Ji turned her head and asked Xu Zheng.

"Well, it's set on the National Day, and there will be holidays at that time, and relatives and friends will also have time."

"Okay, I'll go with your teacher to witness your wedding."

When Xu Zheng heard this, he immediately stood up to express his gratitude, Professor Ji and the old lady hurriedly grabbed him, politely for a while, and the three of them sat down again.

If Professor Ji and Mrs. Ji can attend his wedding, Xu Zheng is very moved, not to mention the identities of the two of them, now in this society, there are several teachers who will attend the student's wedding, and Xu Zheng is only Professor Ji's graduate student at present.

The so-called on-the-job graduate students can't be compared with the graduate students recruited by the unified recruitment, let alone the group of doctoral students.

Mrs. Ji only knew Xu Zheng for a while, and she decided on this matter, this can no longer be said to be a matter of Xu Zheng giving face to the Xu family, this is really valuing herself, and she is treating herself as a master-apprentice relationship.

Although Xu Zheng's parents died, he really hasn't seen too much warmth and warmth when he grows up, he is a descendant of martyrs, and his colleagues and comrades-in-arms on his father's grandfather's side take great care of their family on weekdays, and the community and streets often send people to greet them.

and grandma's old friends also often come and go to the Xu family, and they can help more or less.

It can be said that since he worked, the care of these elders has never been broken, and now that Professor Ji values him so much, how can he not be moved?

Many people don't know the social status of a professor, and they only think that they only enjoy the treatment of the deputy department or the main department, like Ji Dongli, Changming University at the deputy ministerial level, he was the head of the department, and he should have been treated at the deputy department level, but now he enjoys the treatment of the deputy minister.

This is mainly because he was selected as a candidate for academician of the Academy of Engineering, so he currently enjoys the treatment of deputy minister, and it is estimated that in another year or two, he will be an academician of the Academy of Engineering.

Not to mention his reputation, why enjoy the special government allowance of the State Council, won the National Advanced Worker, the National May Day Labor Medal, and the National Public Security System Second-class Heroic Model...

It can be said that his social status and influence are incomparable with ordinary city leaders, and of course there is no real power here.

People at this level have exceeded 99.9% of the 1.3 billion, what children's education, medical services, retirement pension... Ordinary people can't imagine it anymore.

At the very least, if Professor Ji is sick, he is entitled to the top floor of the inpatient building of the Provincial People's Hospital.

After eating a meal for an hour, the three of them chatted casually during the meal, just chatting and chatting, Professor Ji and Xu Zheng talked about Qianji poison again, "Let's just talk about this old duck soup, why do Changming people like to drink it?" It is because Changming is located in East China, the Yangtze River Basin, hot in summer, wet and cold in winter, and old duck soup is the first choice to cool off the heat.

Of course, there are other reasons for this.

Is it okay to use duck soup to poison?

Of course you can, the duck soup has a lot of effects, but people with spleen and stomach deficiency can not drink it often, to put it bluntly, this kind of patient has a large body cold attribute, the duck soup itself is to give people heat, the more you drink the duck soup, the heavier the dampness of this kind of person.

If you add some cold-attribute drugs to the soup, or eat some cold-attribute vegetables and fruits in your life, over time, this person will get stomach cancer, and it will be an advanced stage of stomach cancer.

So you say, is this a chronic poison? ”

Xu Zheng thought for a while, "Spleen and stomach deficiency and cold are generally only experienced by people in the first grade, according to what you said, if it has been this kind of eating habit, it is estimated that the change of the disease will not exceed five years, and five years makes a person have advanced stomach cancer, which can indeed be regarded as a chronic poison." ”

Ji Dongli nodded, "Although we are forensic doctors, forensic medicine and criminal investigation are closely related, many forensic doctors are excellent investigators, and the advanced stage of stomach cancer I am talking about is not made up by me, but it is true."

At that time, I had already begun to preside over the forensic work of our province, and once two middle-aged people were not satisfied with the forensic identification given by the city bureau below, and finally the matter was handed over to me, the deceased had advanced stomach cancer and had surgery, but the cancer cells had spread, and he did not live long after the stomach was completely removed.

The two sons of the deceased did not recognize that his father died of stomach cancer, because the deceased was only 58 years old at the time, and he was in good health, and he was a wealthy man who knew how to take care of himself.

After I took over, I did not repeat the examination of the body, but went to find out why he had stomach cancer, and then I found out that the deceased's wife, who was the stepmother of their sons, used the method I just said to make duck soup for the deceased.

It was as if after three years of marriage, the man fell ill, and his second wife, whose purpose was so clear that she confessed without much interrogation.

Therefore, as a criminal investigator and studying forensic medicine, you must read more books and gain more knowledge, otherwise you will not be able to find many clues even if you are in front of you just by relying on the knowledge in books.

It's like this bowl of duck soup. ”

Xu Zheng nodded hurriedly, he really hadn't heard of the eucalyptus column that Professor Ji said, it seems that to be a qualified criminal policeman, it is not enough to just look at the eucalyptus scrolls, but also to look at the Chinese medicine books and see the compatibility of Chinese medicine.

The more he thought about it, the more reasonable he felt, because the people of the flower country pay attention to health in their bones, and many people don't understand and eat supplements indiscriminately.

Some of the deceased could not find out the real cause of death, so the police treated him as if he had taken tonic medicine and ate it himself, but in fact, it was a knowledgeable person who took advantage of the deceased's eucalyptus made by not knowing the knowledge of tonics.

Seeing Professor Ji and Xu Zheng pointing to the duck soup they had worked so hard to make and saying that it could kill people, Mrs. Ji was dissatisfied, "What do you mean, Ji Dongli, you said this in front of your students, is it harmful for me to boil the soup?"

Don't take a sip of duck soup or eat a bite of my cooking. ”

"Hey, look, look, I'm just making an analogy, using an analogy, how dare I say that your old duck soup is poison?"

Of course, Old Lady Ji would not let him go easily, "Hmph, I don't believe it, you bad old man is very bad." ”

-----------------

At three o'clock in the afternoon, the two old men wanted to rest, Xu Zheng came out of Professor Ji's house, and when he left, Professor Ji gave him several books, asking him to read them in a month, and then go over to change them after reading them, as for Mrs. Ji, she let Xu Zheng take her girlfriend to the house as a guest when she was free.

Of course, Xu Zheng agreed.

Three o'clock in the afternoon in Changming City is the hottest time of the day, even if you walk in the shade of the plane tree, it still feels like a fire, there are so many plane trees in the city, why don't you dissipate heat?

When he got into the car, Xu Zheng regretted it, he should have parked the car on the right, he parked on the left, the sun baked the seat and steering wheel to 80 degrees, and he felt that the skin was hot when he sat down.

Ignition, turn on the air conditioner, turn on to the maximum, open the outer circulation first, and then turn on the inner circulation when it is cool.

At this time, he couldn't go home directly to rest, but according to the positioning sent to him by Han Xin in WeChat, he went to the New Era Hotel on Zhongshan Road, Gulou District, which is a hotel opened by Han Dongwen's friend, not a five-star hotel, but an ordinary business wedding hotel.

What kind of hotel to choose as the wedding scene really needs to be carefully considered, Xu Zheng and Tian Xinyue at home are both official apes, they can't be too high-profile, and the family is not the kind of person who likes to show off, Xu Zheng doesn't care, and Han Xin has no opinion.

Therefore, the three adults in the family are in charge of this matter.

As for Huang Xinyi, this time she did not provide Han Xin with any reference for high-end clubs, five-star hotels, and resorts, because she also felt that Han Xin and Xu Zheng's marriage should not be too high-profile.

Including the wedding car, of course she had a relationship to find a better one, but she didn't say it, because Han Dongwen insisted that she just use her relatives' cars to make it together, and grandma and Aunt Tian also meant this, so the wedding car was decided.

As for the float, I chose and chosen, and I still used Huang Xinyi's white two-seater sports car.

Xu Zheng rushed to the hotel, and as soon as he entered, he saw Han Xin and them sitting in the rest area on the first floor waiting for him.

Xu Zheng didn't understand these things at all, otherwise he would be the party concerned, and he wouldn't want to come.

As soon as he arrived, Han Dongwen and the hotel owner came over, and the people on both sides exchanged pleasantries for two minutes, and then this Uncle Xie personally took them to visit the hotel.

Although it is not as good as a five-star hotel, it is also a sparrow although it is small, and it is complete, and the wedding scene is set in the box of the Peony Hall, which can accommodate 800 people, of course, if you squeeze it, you can sit more.

As for the banquet and the table, the drinks, etc., Han Dongwen talked with the boss, Xu Zheng came today to taste the food, he didn't want to participate in other things, and Han Dongwen didn't take the initiative to pull him to talk about these.

Including the hotel owner, this shrewd Boss Xie, if in the past, like Xu Zheng, the 24-year-old squadron leader of the criminal police detachment of the city bureau, not to talk about his family background, he himself is worthy of the boss to befriend, maybe in a few years, this Xu squadron will become the Xu brigade...

It's just that on this occasion today, no matter how powerful Xu Zheng is, he is also a child, and he has to call the hotel owner Uncle Xie.

This kind of human affection, how can Boss Xie not understand, he has even thought about it, on the eleventh day, there will be a few more male waiters in the box of the Peony Hall, not to work, but to prevent troublemakers...

At five o'clock in the afternoon, a table of ten meat and ten vegetables plus fruits and staple food for the wedding banquet was placed on a large private room table, and Boss Xie left the space to Xu Zheng and his family after drinking a few glasses of wine with Han Dongwen, well, there is also a Huang Xinyi.

"I chose 1999 for this private table, including drinks and drinks, as for the wedding officiant or something, what do you think?" Han Dongwen looked at the dishes and tasted them and thought it was good.

Grandma Su Yuntong took the lead in saying: "I think the decoration of this box is the main wedding banquet, fashionable and beautiful, atmospheric and not cheesy, I think it is okay, as for the pricing of the private table, I also think it is appropriate, no matter how high it is, it is not in line with the identity of our family." ”

Tian Xinyue also nodded after eating a few dishes, "I think I'll choose this one, if this matter drags on, there are so many people who are married in Eleven, it won't be good if you can't find a hotel." ”

"It's okay Aunt Tian, the hotel can't be found, let's go to the resort, this must be no problem." Although Huang Xinyi also thinks that this place is suitable, she still hopes that Han Xin's wedding can be on the outdoor lawn, surrounded by flowers, but unfortunately Changmingren can't get married at night, otherwise under the starry sky, fireflies flying, wouldn't it be beautiful?

Han Xin didn't care where she chose for the wedding, she also looked at the box just now, and when she stood under the catwalk, she began to imagine herself, Hongshang Xia shook her crown step by step, and she was tired of Pei Shanshan, "I also agree to choose here, besides, this place is not far from our house, which is convenient." ”

Huang Xinyi teased her, "You can't wait to marry Xu Zheng." ”

"What's the matter, do I still need to be in a hurry?" Of course, Han Xin couldn't admit it in public, so he pulled Huang Xinyi and the two of them to start talking.

Now it depends on Xu Zheng's opinion, Xu Zheng saw that everyone looked at him, "I have no opinion, I have seen this hotel, there is accommodation, and it is convenient for relatives and friends from other places to arrange it directly here." ”
