Shi Mingliang looked at the two evidence bags unwillingly: "Boss Wen, could it be that the tea drinker added it himself?" Boss Wen covered his mouth and smiled softly: "Mr. Officer, this question of yours is really interesting. Pen, fun, pavilion www. biquge。 infoI don't know this tea drinker, how do I know if he will add something to it himself? But I don't think this leaf has any special smell, and it will not be used to enhance the aroma of tea. If it has any special effects, it should not be brewed with tea. ”

"I'm just guessing." Shi Mingliang scratched his head a little embarrassed. Ning Zhiyuan bowed slightly to Boss Wen and said, "Thank you, Boss Wen." "You're welcome, Mr. Officer, I didn't help much." Boss Wen replied generously, "If you need anything in the future, just come over." ”

Ning Zhiyuan smiled and was about to leave the tea house with Shi Mingming, but he just walked to the door and remembered something, turned around and said, "Boss Wen, do you have the Longjing before the Ming Dynasty here?" "Of course," Boss Wen said, pulling his shawl, "I don't know what quality Mr. Police Officer wants, do you give it away or drink it yourself?" ”

"Drink it yourself, it's better." Ning Zhiyuan replied. "Please come upstairs with me, there are several Mingqian Longjing upstairs with quite good quality." Boss Wen made a gesture of please.

The second floor of the tea house is obviously a higher level than the decoration on the first floor, and there are various boutique gift boxes on the antique Bogu cabinet. In the room, there is a large tea table in the shape of a log, on which are all kinds of tea utensils. Boss Wen sat Ning Zhiyuan and Shi Mingliang at the tea table and took three tea boxes from the Bogu shelf.

"These are all good Ming Qian Longjing," Boss Wen opened a tea box and handed it to Ning Zhiyuan, "You can smell the tea aroma of this dry tea first and see which one you like." ”

Boss Wen brewed a pot of each of the three kinds of tea, so that Ning Zhiyuan could taste it brightly. Shi Mingliang usually doesn't drink much tea, but he is also attracted by the fragrance of tea. After Ning Zhiyuan tasted three kinds of tea, he pointed to one of the cups and said, "Just like this." ”

"It seems that Mr. Police Officer is a person who understands tea, and although this tea is not the most expensive of the three, I think it is of the highest quality." Boss Wen looked at Ning Zhiyuan seriously, "Mr. Police Officer usually drinks tea, right?" ”

Ning Zhiyuan waved his hand humbly: "My girlfriend likes this kind of tea, and I usually taste it with her." "Oh, I see. It seems that Mr. Officer's girlfriend should be a classy person. Boss Wen nodded knowingly, "Mingqian tea should not be stored for a long time, and it is not easy to store, let's come less first, and you can buy it again after drinking." ”

"Okay, thank you." Ning Zhiyuan waited for Boss Wen to weigh the tea, and after paying the money, he left the tea house with Shi Mingming.

Back in the office of the special case team, Ning Zhiyuan put the tea in the drawer of his desk, and suddenly remembered that Jing Jing had said that drinking tea can detoxify the fire, and a thought flashed in his mind, but it was a little unpredictable. He pulled out his phone and dialed the quiet call.

Jing Jing was in the office with the new doctor to explain some precautions in the department, the mobile phone rang, she took it out and saw that it was Ning Zhiyuan, and said "sorry" to her colleagues, Ning Zhiyuan rarely called her during the daytime working hours, at this time, there must be something. She hurriedly returned to her desk and picked up the phone: "Zhiyuan, is there something wrong?" ”

"Jing, I remember you said that drinking tea can detoxify the fire, right?" Ning Zhiyuan's deep and magnetic voice came. Quiet chuckled: "What? I'm on fire again about the case and want to drink tea? ”

"No, I just want to know if if a substance is soaked in water with tea, will it change the original composition of the substance." Ning Zhiyuan said with a frown.

"Well, it's possible, but instead of changing the original composition of the substance, it will decompose some of the ingredients or reduce their efficacy." Quietly replied affirmatively, "Tea contains tea polyphenols, which are the general term for polyphenols in tea, including catechins, flavonoids, etc., which have detoxification and anti-radiation effects. Therefore, drinking tea regularly has a good health care effect. ”

"But......" Ning Zhiyuan wanted to continue asking, but he didn't know how to describe it, "Forget it, I can't tell you clearly, I'll pick you up after work at night, you can help me take a look." ”

Jing was confused by Ning Zhiyuan's words, and he didn't understand what he asked him to help him see, so he didn't ask much, and promised him to wait for him in the hospital after work.

After getting off work in the evening, Ning Zhiyuan picked up Quiet and found a private teahouse for dinner. After returning to Jingjing's house, Ning Zhiyuan showed her a few leaves he brought.

Jing looked carefully under the lamp for a long time, frowned slightly and said, "This is not tea, it looks a little like oleander leaves, but I'm not very sure." ”

"Oleander?" Ning Zhiyuan was a little surprised, "Isn't that a very toxic plant?" I remember when I was in school, my teacher used to say that it was extremely toxic, and there were reports of small fatalities. ”

"Yes," nodded quietly, "oleander was once listed as one of the most poisonous plants in the world, and it contains a variety of toxins. The most abundant toxin is oleandrin, a cardiac glycoside. This toxin has both positive and toxic effects on the heart. Moreover, the whole oleander is toxic, in which the flowers are relatively less toxic, and there are more branches and leaves. In particular, the leaves are toxic even if they are dried up and the smoke from incineration is generated. ”

"That's right." Ning Zhiyuan said thoughtfully. "What's right?" Quiet and puzzled. Ning Zhiyuan came back to his senses and said: "The cause of death of the deceased is because the blood contains a large amount of cardiac glycosides, which leads to severe heart failure. But there is one thing I still don't understand, why this kind of leaf mixed with tea can't detect the toxin? Could it be that it is decomposed by the tea polyphenols in the tea leaves? ”

Quiet wrinkled his eyebrows and thought for a moment: "It should be like this, different things release their contents at different times after being soaked in water. Maybe oleander in the water release oleandrin in the speed is faster than the tea release of tea polyphenols, or put in oleander first, and then put the tea, people will be poisoned after drinking, but after a long time of soaking, the tea polyphenols will decompose the toxicity inside, and then the detection will not be able to detect the toxic components. ”

Ning Zhiyuan's eyes lit up: "Jing, what you said makes sense." "I'm just guessing, I'm not really sure." Quiet smiled, "If you want to know the exact results, it's best to confirm them by conducting further experiments." ”

"Well, I'll let Mingliang and Zhang Wei conduct experiments early tomorrow morning." Ning Zhiyuan looked at Jing Jing with surprise in his eyes, "How can my daughter-in-law know so much!" ”

Mr. Star said

Happy Chinese New Year and all the best!
