I don't want to solve the case when I'm a little policeman.

Chapter 410 Professor Ji's Approval
When Professor Ji Dongli saw Xu Zheng asking about poisons, his good teacher side began to play a role. He pulled Xu Zheng to chat about poisons. He told him many kinds of poison prescriptions synthesized by modern scientific and technological methods, and the two had a good chat.

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

Like ricin, 1 gram is enough to kill 3600 people.

There are also some elements purified from minerals, such as chlorine and arsenic, mixed with some other compounds, the lethal rate is very high, the victim's body surface basically shows no signs of poisoning, and this compound only has a faint almond smell, 40 % of people can't smell it.

Most of the poisons studied by modern people are toxins that act on the nerves, such as tetrodotoxin. Combined with other compounds, it can completely kill a person instantly, and this drug cannot be found in ordinary autopsies.

The reason why Xu Zheng asked about Qianji Poison was because of the case that the large team was currently investigating. He didn't know the specific process of the suspect's crime. It's just that the autopsy results of the deceased were a bit weird. Today, he just took this opportunity to ask Professor Ji.

Ji Dongli raised his glasses, his gray eyebrows frowned, "Xiao Lu from your city bureau sent me information about the case you mentioned, and we haven't come up with the specifics yet. Not at work?
Then you can come to the provincial inspection department tomorrow and learn along with it. "

Such a good learning opportunity Xu Zheng definitely wants to go, but, "I don't know tomorrow. This case is currently in charge of the first team. Our second team has just been on a business trip for more than ten days. This work will probably come soon. The teacher Can you send me a copy of the inspection materials, to tell you the truth, I am quite curious about this case."

Ji Dongli knew that the criminal investigation was busy, so he didn't care much about whether Xu Zheng could come, "That's fine, but if you are really interested, you should go to the forensic department of your city bureau to have a look at the deceased's body in person. Further investigation is unavoidable."

Xu Zheng nodded quickly. Although he didn't have a formal forensic qualification certificate, nor was he the criminal investigator in charge of this case, but with his current skills and his relationship with Lu's forensic doctor, it was still possible to observe their autopsy process.

"Stop chatting, you two, come out to eat." Mrs. Ji called them out to eat when she saw that the two had been chatting for more than half an hour.

I have to say that the old lady is also a fastidious person, and all the food is Chang Ming’s taste. She also prepared four dishes and one soup for the three of them. The soup is old duck soup. The casserole boiled for over an hour.

Seeing Xu Zheng and the others come out, the old lady smiled and said: "Xiao Xu, go wash your hands and prepare to eat. This is the first time you have come to our house as a guest. I don't know what your taste is. If it is delicious, you should eat more. Otherwise, the old couple of us will not be able to finish eating."

"Master's mother's food looks like the craftsmanship of the old Changming people, especially the old duck soup. You can tell it's delicious when you smell it."

Ji Dongli raised his hand, "The bathroom is over there, hurry up, I have to check your homework after dinner."

When Xu Zheng came out after washing his hands, the old lady had already specially served him a bowl of old duck soup. It counts as a meal."

As they got closer, Xu Zheng took a closer look at the old lady, and said that it was an old lady. According to Ji Dongli's age of 61, the old lady was probably about the same. The reason why the two of them looked old was that their hair was not dyed.

If Andy Lau had gray hair on the screen, the 62-year-old would never look like 52.

"I heard that your grandma is still alive. She is a nobleman this year?" Mrs. Ji chatted with Xu Zheng during the meal.

Xu Zheng hurriedly swallowed a mouthful of salted duck, "My grandma is 67 this year, is she ten years older than you?"

"Hey, how can I be so young, I am 65 this year, I am 4 years older than your teacher, time is not forgiving, I don't show when I am young, now I am older, I am much older than him. "The old lady didn't know why, but she liked Xu Zheng very much when she saw her. Basically, she didn't eat much food, she was busy adding food to Xu Zheng.

"Cough cough. What are you talking about, what are you not old? How can I despise you for being old?" Ji Dongli pretended to cough twice to remind his wife and change the subject.

It's a pity that Mrs. Ji didn't pay attention to his words, "Xiao Xu, no, let me call you Xiaozheng. Speaking of which, my granddaughter should be four years younger than you. She is a sophomore or a junior this year. She is in our medical department. In my heart, doctors and forensic doctors happen to have a common topic, you young people have a chat when you have time."

"Don't be so busy, Xiaozheng is going to get married in October this year, you are too late." Ji Dongli looked at Xu Zheng, and an idea came to his mind, it would be great if this was his grandson-in-law.

But adults can naturally control their own thoughts, and so is Mrs. Ji. Disappointed, she asked curiously, "Xiaozheng, aren't you only 24 years old? Is it 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 give you Say this."

"Four or five years old, alright, female juniors holding gold bricks, October, is the National Day to get married?" Mrs. Ji turned her head and asked Xu Zheng.

"Well, it's National Day. There will be holidays, and relatives and friends will also have time."

"Okay, then I will go with your teacher to witness your wedding."

As soon as Xu Zheng heard this, he immediately stood up to express his thanks. Professor Ji and the old lady quickly held him back, and after being polite for a while, the three of them sat down again.

If Professor Ji and Mrs. Ji could attend his wedding, Xu Zheng would be very moved. Regardless of their identities, in this society, there are several teachers who will attend student weddings, and at present Xu Zheng is only Professor Ji's incumbent. postgraduate.

The so-called on-the-job graduate students are simply not comparable to the unified recruited graduate students, let alone the group of doctoral students.

Mrs. Ji has only known Xu Zheng for a while, and she has decided on this matter. This can no longer be said to be a matter for Xu Zheng and the Xu family's face. up.

Although Xu Zheng's parents passed away, he has never seen much warmth and warmth when he grew up. He is a descendant of a martyr. His father and grandfather's colleagues and comrades-in-arms usually take good care of their family, and the community and the street often send people Come and say hello.

There are also grandma and those old friends who often come and go to Xu's house, and they can help more or less.

It can be said that since he started working, these elders have never stopped caring for him. 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 at the deputy department or the department level. For example, Ji Dongli, who is at the Changming University at the deputy ministerial level, used to be the dean of the department, so he should have been treated at the deputy department level. But now he enjoys deputy ministerial treatment.

This is mainly because he was selected into the candidate list of the Academy of Engineering, so he currently enjoys the treatment at the deputy ministerial level. It is estimated that in one or two years, he will be an academician of the Academy of Engineering.

Let’s talk about his reputation, why he enjoys special government allowances from the State Council, won the National Advanced Worker, the National May [-]st Labor Medal, and the second-level hero model of the National Public Security System.
It can be said that his social status and influence are incomparable to the leaders of ordinary cities. Of course, we are not talking about real power here.

This level of people has exceeded 13% of the 99.9 billion people. What about children's education, medical services, and retirement pensions... ordinary people can no longer imagine.

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

After eating a meal for an hour, the three of them chatted casually during the meal, just chatting, Professor Ji and Xu Zheng talked about Qianjidu again, "Let's just talk about this old duck soup, why did Chang Ming Do you like to drink? Because Changming is located in East China, in the Yangtze River valley, where it is hot in summer and cold in winter, and Lao Ya Soup is the first choice to cool off the heat.

Of course there are other reasons.

Can the old duck soup be poisoned?
Of course it is possible. The old duck soup has many effects, but people with weak spleen and stomach cannot drink it often. To put it bluntly, this kind of patient has a strong cold attribute. The old duck soup itself clears away heat for people. The more you drink the old duck soup, This kind of person is more humid.

If you add some cold medicine to the soup, or eat some cold vegetables and fruits in your life, over time, this person will definitely get stomach cancer, and it will be the advanced stage of stomach cancer when it is discovered.

Then you say, is this a chronic poison? "

Xu Zheng thought for a while, "Spleen-stomach deficiency and cold are usually found in seniors. According to what you said, if this eating habit has been maintained, it is estimated that the symptoms will not change for more than five years, and five years will make a person Having advanced gastric cancer is indeed 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. The terminal stage of gastric cancer I mentioned is not made up by me, but has other facts. thing.

At that time, I had already started to preside over the forensic work in our province. Once two middle-aged people were dissatisfied with the forensic appraisal given by the city bureau below. Finally, the matter was handed over to me. The deceased had advanced gastric cancer and underwent surgery, but the cancer had spread. Cut off the stomach did not live long.

The two sons of the deceased did not agree that his father died of stomach cancer, because the deceased was only 58 years old at the time, he was in good health on weekdays, 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 corpse. Instead, I went to find out why he had stomach cancer, and then I found out that the wife of the deceased, who was the stepmother of their two sons, used the method I just mentioned to often cook duck soup for the deceased. .

It seemed that after three years of marriage, the man fell ill, and his second wife, whose purpose was obvious, confessed without much interrogation.

Therefore, as a criminal investigator, if you are studying forensic medicine, you need to read more and gain more knowledge. Otherwise, you will not be able to discover many clues even if you just rely on the knowledge in books.

Just like this bowl of old duck soup. "

Xu Zheng nodded quickly. He really hadn't heard of the case Professor Ji talked about. It seemed that to be a qualified criminal policeman, it was not enough to just read the case files. He also had to read the books of Chinese medicine and the compatibility of Chinese medicines.

The more he thought about it, the more he felt that it was reasonable, because people in the flower-growing country pay attention to health preservation in their bones, and many people take supplements indiscriminately if they don't understand. These days, when people have money, many people die because of eating supplements indiscriminately or wrongly.

Some of the deceased were unable to discover the real cause of death, and the police assumed that he had eaten tonics and died. In fact, knowledgeable people took advantage of the deceased’s lack of knowledge of tonics to do the case.

Seeing Professor Ji and Xu Zheng pointing to their hard-boiled old duck soup and insisting that it can kill people, Mrs. Ji was dissatisfied, "Ji Dongli, what do you mean, you said that in front of your students , Could it be that I made the soup to harm you?

Don't drink a sip of old duck soup in the future, don't eat a sip of rice I made. "

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

Of course, Mrs. Ji would not let him go easily, "Hmph, I don't believe it, you are a very bad old man."
-
At three o'clock in the afternoon, the two old people were going to rest. Xu Zheng came out of Professor Ji's house. When he left, Professor Ji gave him several books and asked him to read them in a month, and then go to change after reading them. When I am free, I bring my girlfriend to my house as a guest.

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 trees, you still feel as if you are on fire. There are so many plane trees in the city, why don't they dissipate heat?
When he got into the car, Xu Zheng regretted it. He should have parked the car on the right side. He parked on the left side. The sun had baked the seats and steering wheel to [-] degrees, and it felt like the skin was scalding when he sat on it.

Turn on the ignition, turn on the air conditioner, turn it on to the maximum, turn on the outer circulation first, and then turn on the inner circulation when it cools down.

At this time, he couldn't go home and rest directly. Instead, he went to the New Era Hotel on Zhongshan Road, Gulou District, according to the location Han Rui sent him in WeChat. This is a hotel opened by Han Dongwen's friend. It's not a five-star hotel, but a Ordinary business wedding banquet hotel.

What kind of hotel to choose as the wedding venue really needs to be carefully considered. Both Xu Zheng and Tian Xinyue at home are business apes, so they can't be too high-profile, and the family members are not the kind of people who like to show off. Xu Zheng doesn't care, and Han Rui has no opinion.

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

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

Including the wedding car, of course she has something to do with finding a better one, but she didn't say anything, because Han Dongwen insisted on using the cars from relatives' homes to make up one. Grandma and Aunt Tian also meant the same, so the wedding car was settled like this.

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

Xu Zheng rushed to the hotel. As soon as he entered, he saw Han Rui and the others sitting in the rest area on the first floor waiting for him. Today, he mainly came to try the meals to see if the dishes for the table were satisfactory, as well as the types of drinks.

Xu Zheng didn't understand these things at all, or else he was the person involved, and he wouldn't even want to come.

No sooner had he arrived than Han Dongwen and the hotel owner walked over. They greeted each other for 2 minutes, and then Uncle Xie personally showed them around the hotel.

Although this place is not as good as a five-star hotel, it is still small and well-equipped. After walking around, the wedding venue is set in a box in the Peony Hall, which can accommodate 800 people. Of course, if you squeeze it, you can sit more.

As for the banquet table, drinks, etc., Han Dongwen discussed with the boss. Xu Zheng came here today to taste the dishes. He didn't want to participate in other things, and Han Dongwen and the others didn't take the initiative to drag him to discuss these.

Including the owner of the hotel, 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, regardless of his family background, he himself was worthy of the boss's friendship, maybe in a few years, This Xu Squadron became Xu Brigade
It's just that on this occasion, no matter how powerful Xu Zheng is, he is still a child, so he has to call the hotel owner to thank his uncle.

How can Boss Xie not understand this kind of human kindness, he has even thought about it, on the eleventh day, there will be a few more male waiters in the boxes of the Peony Hall, not for 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 was placed on the table in a large private room. After drinking a few glasses of wine with Han Dongwen, Boss Xie left the space for Xu Zheng and his family. Well, there is another Huang Xinyi.

"I chose 1999 for this table package, which includes wine and beverages. As for the wedding officiant, what do you think?" Han Dongwen looked at the dishes, tasted them and thought they were good.

Grandma Su Yuntong said first: "I think the decoration of this box is mainly for wedding banquets. It is fashionable and beautiful, and the atmosphere is not tacky. I think it is okay. As for the price of the private table, I also think it is appropriate. No matter how high it is, it will not be in line with our family's identity. "

After eating a few dishes, Tian Xinyue also nodded, "I think I'll choose this one. If this matter drags on, there are so many people getting married on November [-]st. It would be bad if they can't find a hotel."

"It's okay, Aunt Tian. We can't find the hotel. Let's go to the resort. It's definitely okay." Although Huang Xinyi also thinks that this place is suitable, she still hopes that Han Rui's wedding will be on the outdoor lawn, surrounded by flowers, which is a pity Changming people can't get married at night, otherwise, wouldn't it be beautiful under the starry sky with fireflies flying around?
Han Rui didn't care much about where to choose for the wedding. She also looked at the box just now. When she was standing under the runway, she began to imagine herself, Hongshang Xia wearing a crown shaking her head, Tin Ying tired of Pei Shanshan, "I also agree to choose Here, besides, it’s not far from our home, so it’s convenient.”

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

"Why, should I be in a hurry?" Of course, Han Rui couldn't admit it in public, so she dragged Huang Xinyi and the two of them to start small talk.

Now it's up to Xu Zheng's opinion. Xu Zheng saw that everyone looked at him, "I have no objection either. I've seen this hotel. There is accommodation. It will be convenient for relatives and friends from other places to arrange here directly."
