An authentic old hot pot restaurant, in a private room.
The store manager personally arranged the ingredients for several people, and instructed some special ingredients to be cooked for a few seconds to taste the best, and left a waiter to serve at the door of the box, and then withdrew.
I came to eat it, and the ingredients were cooked, and everyone was welcome.
Wu Duan ate well, and turned down the temperature of the air conditioner to a low level.
Yan Sixian took the remote control and took a look, and found that the temperature had been adjusted to 18, although it was not blowing directly at the person, but the wind was very cold, and it drilled into the cracks of the human bones around the bend, and felt that it was not good, so he adjusted the temperature back to 27, and continued to study the necklace with experts in the field of biology.
The expert is over half a hundred years old, wearing glasses with a limited number of thinner points than the bottom of a beer bottle, listening to Yan Sixian talk about the origin and function of the necklace with a little concealment, took out a small magnifying glass from his pocket, and looked at the oval golden translucent necklace pendant again and again, and was surprised again and again.
After looking at it for a few minutes, the expert finally straightened his head, "Well, although it's strange, I probably know what it is, it's indeed a treasure." ” Hearing what the expert said, Yan Sixian put the pendant in his palm preciously.
"What is it?"
"It's some kind of insect organ, ant queen or queen bee or something, I can't see what kind of it is now, and I have to use an instrument for further testing."
As soon as he heard that it was something on the insect's body, Yan Sixian was a little jealous, no longer holding the pendant directly, but carrying the rope that had just been changed on the way when he came, and asked, "What kind of organ is that?"
"Some kind of organ for secreting pheromones, different insects, different organs secreting pheromones, so it's hard to say."
Seeing that Yan Sixian heard the cloud and mountain fog, the expert said again: "I'll take ants as an example."
When I used to go on a scientific expedition with my teacher, I went into the mountains at the intersection of Guangxi and Yunnan, and I saw a nest of ants that had grown and multiplied for seventy or eighty years, and the queen was more than ten centimeters long.
It has an organ that specializes in secreting pheromones.
Pheromones, you can understand as a tool used to communicate between ants.
The queen ant controls and influences the ant colony through pheromones, and the most obvious control is to inhibit the egg-laying function of the worker ants, and the study has confirmed that the worker ants can actually lay eggs, but because of the influence of the queen's pheromones, this function is inhibited, and if the queen of an ant colony dies, then the egg-laying function of the worker ants will soon recover.
When the leader of an insect population like the queen ant is strong enough and secretes enough pheromones to be so strong that it can even affect other insect populations around it, forcing them to migrate farther away.
I think the reason why your necklace pendant has a mosquito repellent effect is this principle, ordinary insects receive the smell of pheromones in the necklace pendant, feel the danger, and instinctively avoid it. ” Yan Sixian suddenly realized, "I see. ” He drew inferences again: "Then it seems that the reason why I was carried away by the ear drill is because they are affected by pheromones, thinking that I am their leader, what should I say?"
The expert looked at him with relief behind the glasses, opened his mouth, and finally didn't dare to boast of the sentence "children can be taught".
Bowing his head and rubbing his nose, the expert continued: "It should be what you think, you just caught up with a few crickets, that's what you said about ear drills, a few ear drills are fighting in a crowd, because of pheromones, some ear drills treat you as the same kind."
Because of this, you have been repeatedly attacked by the Ear Drill King. ” "Understood."
Yan Sixian found it interesting, and while playing with the necklace in his hand, he beckoned the expert to eat.
Sherlock listened to a half-understood, and when he didn't understand, he asked Wu Duan, and when Wu Duan didn't know how to explain, he turned out the Chinese-English translation function on his mobile phone and converted Chinese words into English to show him.
Yan Sixian asked again: "Then if I keep bringing this thing with me, it won't be any side effects if I use it when there are mosquitoes in the summer."
"Theoretically, no, but," the expert put down his chopsticks and pondered for more than ten seconds, "but it's better not to wear them." ” "Why" "It's so big, it's the first time I've seen it, the pheromone level is too strong, maybe it also involves insect mutations, besides, this thing can be preserved, and it doesn't affect the pheromone diffusion in it, and the processing technology is not ordinary, maybe it's lost now anyway, I haven't heard of this technology in the industry, anyway, maybe it's infertility or something."
"Poof" Wu Duan couldn't hold back, the fat cowroll in his mouth almost squirted out, and he hurriedly lowered his head.
Although he didn't see it at the first time, as soon as he imagined Yan Sixian's expression at the moment, he couldn't stop laughing, and his shoulders shook vigorously, and the abdominal muscles on his stomach felt sore.
Then, he felt that Yan Sixian had accurately found his hand on his knee under the table, and stuffed something into his hand at lightning speed.
"I'm going to cut off your dog's head" Now, it was Yan Sixian's turn to laugh.
Wu Duan threw the necklace on the table, and unmasked without hesitation: "Save it, I'll touch it at most, you've been carrying it for a few days, the ghost knows if you have to hold it when you sleep, or I'll send you to the hospital for a check-up later."
Yan Sixian's face had never been so dark.
Wu Duan: Please call me the little prince with a heart.
Yan Sixian: You wait, you wait for the surname Wu, I'll write you a small notebook A few people chatted a few more words, and the biology expert pointed to the necklace on the table and said, "Can I take it back for a few days I still know a few entomology experts and want to study and study together." ” Yan Sixian immediately said suspiciously: "Dean Li" The biologist, whose surname is Li, is the dean of the School of Bioengineering at a 985 university.
"Dean Li, do you want to take things away and deliberately talk to me about infertility?"
"Absolutely not."
Dean Li had a hurt expression on his face, "Xiao Yan, how can you think of me so much", which was quite a bit of relying on the old and selling the old, which made Yan Sixian very untempered.
Seeing that Yan Sixian was deflated, Wu Duan smiled secretly again, and sighed with emotion.
Dean Li repeatedly assured that their research and testing would never damage the necklace pendant, and it would be completed in a few days.
Yan Sixian looked at Wu Duan, which meant "This is my leader, and I can only agree if he nods."
Wu Duan thought for a while and said to Dean Li: "It is naturally good to be able to contribute to scientific research, but you borrowed it from Xiao Yan through a personal relationship, and please do not mention the origin of this thing in the written materials you left during your research, so as not to cause us all trouble in the future." ” Dean Li understood, and repeatedly assured that in the end, it was Wu Duan who provided a gift bag, and Dean Li happily and carefully put the necklace into the evidence bag, it seemed that in his eyes, this was really a treasure
