Quietly, Ning Zhiyuan's face turned crimson by Ning Zhiyuan's words, and he said angrily: "Who is your daughter-in-law, and nonsense." Pen ~ Fun ~ Pavilion www.biquge.info" Ning Zhiyuan smiled and pinched her face: "You, do you still want to be someone else's daughter-in-law?" But, Jing, how do you know this? ”

"My mom used to work at the Institute of Pharmacology." Quiet's face darkened, "There are a lot of books on pharmacology at home, and I will read them when I am free." There are books that record various plant pharmacological knowledge. ”

"Oh, by the way, today I bought some Longjing tea from before Ming, which is similar to the one Mina gave you." Ning Zhiyuan knew that it was quiet and remembered the sad past, so he quickly diverted the topic and went to the coat pocket on the hanger at the door and took out a delicate small tea box.

Quiet took the tea box and opened it and smelled it: "Well, the fragrance is about the same." How did you remember to go buy tea? "Today I went to the tea house and asked the boss to help identify these brewed tea leaves. Knowing that you like to drink this tea, I bought some by the way. Ning Zhiyuan rubbed his quiet head, thought about it and said, "When this case is closed, I must thank you well." Think about it, what do you want? ”

Quietly took Ning Zhiyuan's arm and rested her head on his shoulder: "I don't want anything." If what I'm saying really helps you, then I'm happy. ”

Ning Zhiyuan kissed her forehead, and smiled dotingly: "Of course you helped me, I found that you can always wake me up at critical moments." Well, when the case is closed, how about I apply for two days off to take you out to have fun? ”

"Okay," Quiet nodded happily, "It's Labor Day, and I have time, if you can really rest for two days, we can go on a hike together." ”

"Then let's settle it." Ning Zhiyuan pinched his quiet fingers in his palm, a thought flashed through his mind, and he smiled secretly.

As soon as he got to work the next day, Ning Zhiyuan gathered the people of the special case team and told everyone about the quiet speculation. "Oleander?" Zhang Wei touched his chin thoughtfully, "If this is the case, it can explain why Fu Xiaofan and Su Ziming's blood contains a large amount of cardiac glycosides." ”

Fang Jianye's eyes widened in disbelief: "I've also heard that oleander is a poisonous plant, but I didn't expect it to be so toxic." ”

"Do you know about Chloe in the United States?" Zhang Wei raised his eyebrows and asked. "Chloe?" Fang Jianye scratched his head, "My nephew plays a game called "Sailor", and there is an elf who seems to be named Chloe. ”

"What a mess," Zhang Wei gave him a look of disdain, "There is a famous attraction in Francisville, USA, called Changchun Garden, which has a history of more than two hundred years. In the 18th century, the owner of the garden left it to his daughter and son-in-law. Chloe was a slave in the garden, and after being insulted by the man, she held a grudge and tried to poison the man by using the leaves of the poisonous oleander in the garden to bake bread. But without thinking about it, he poisoned the mistress and her daughter. Chloe was remorseful and committed suicide by jumping into the Mississippi River. Local legend has it that her ghost remained in the Garden of Changchun after her death. ”

"Hey," Chen Feng touched his arm and shuddered, "Don't you say it so miserably!" Ning Zhiyuan chuckled: "It's just a legend, but there are still cases of oleander death." This plant is poisonous throughout the plant, especially the branches and leaves, which are the most toxic. What we need to do now is first, to confirm that the tea leaves are oleander leaves. Second, what kind of method can be used to make the soaked leaves undetectable for toxicity. Third, the origin of this leaf. ”

"Now we can experiment with oleander leaves, but where do we get them?" Shi Mingliang said with a frown.

"This shouldn't be difficult," Ning Zhiyuan smiled, "After a while, you and Zhang Wei will go to the Institute of Botany in City D, first, to consult experts if this leaf is oleander." If yes, ask them where they can find this leaf. Once you find it, come back and do the experiment right away. ”

"What about us?" Chen Feng asked. "The three of us will go to Fu Xiaofan's house again," Ning Zhiyuan narrowed his eyes, "I think we may find some clues." ”

The weather in the city of D is very fast in the spring, and the weather is still a little cold at the beginning of April, and the temperature immediately rises to 17 or 8 degrees in mid-April. When Ning Zhiyuan and the three arrived at Fu Xiaofan's villa, Mrs. Yu was arranging flowers and trees in the courtyard. "Old lady Yu, why did you do it yourself and didn't let the gardeners do it?" Ning Zhiyuan got out of the car and walked to Mrs. Yu and asked.

"Oh, it's Mr. Officer." Old Mrs. Yu stood up and took off her gardening gloves, "Flowers and plants are also spiritual, and workers only care about their work, and they don't treat them with their hearts. You see, I basically planted it myself. In the spring, tidy up the garden, and it will be beautiful in the summer. ”

"Old lady Yu, what kind of flowers are you growing in this garden?" Chen Feng looked interested. Mrs. Yu was also very happy to see that he was interested, and pointed to the garden and said, "The back against the wall are all climbing vines, fruit trees and greens here, and all kinds of flowers and plants there. In the summer, our family eats the vegetables grown in this garden and rarely goes out to buy them. ”

Ning Zhiyuan looked at the half of the garden where flowers and plants were planted, where in addition to some plants planted on the ground, there was also a small flower shed. He pointed to the trellis and asked, "What is it for?" "That's the flower shed," replied the old lady, "and some of the flowers are not hardy and need to be put in the trellis for the winter." I plant them in pots, move them into the trellis in the winter, and then move them out when the weather is warmer in the spring. "It's tiring enough for you to do all the work yourself." Ning Zhiyuan smiled and said. "I'm not tired," Mrs. Yu waved her hand, "It's just a workout, and Xiaofen will help me usually." ”

"Grandma, the tea is ready." While a few people were talking, Xiao Fen came out of the room with a cup, saw Ning Zhiyuan and the others, and whispered, "Hello Mr. Officer." ”

"Let's go, let's go inside and talk." Mrs. Yu took the cup in Xiao Fen's hand and beckoned a few people into the villa together. Entering the living room, Mrs. Yu instructed Xiaofen to make tea, Ning Zhiyuan stood up from the sofa and said, "I'm going with you, just to see your tea." Xiao Fen was stunned, and Mrs. Yu waved her hand at her, and then she nodded: "Captain Ning, come with me." ”
