Chapter Twenty-Six—Explanation Is Better Than Demonstration [II]

Li Qingshan nodded with satisfaction when he saw him agree, and after a moment of silence, he suddenly asked, "Uncle Niu, are you afraid of being hot?" ”

"Of course I'm afraid of getting hot!" Niu Laosan replied without thinking about it, "Dead pigs are not afraid of boiling water, and I am not a dead pig, of course I am afraid of scalding!" ”

"Uncle Niu, I didn't say you were a dead pig," Li Qingshan hurriedly clarified with a smile, "Don't say that dead pigs are not afraid of being hot, they are not afraid of anything." Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoBut there's a creature that's really not afraid of the heat, and when they see the fire, they rush to it......"

"Huh? Is there such a stupid thing in the world? ”

Niu Laosan's mind didn't turn for a while, and Huang Cun next to him withdrew his affectionate gaze from the poor stool, turned his head and asked, "Baby, are you talking about moths?" ”

"That's right," Li Qingshan nodded approvingly, "It's a moth." ”

Huang Cunzheng smiled and glanced at Niu Laosan, "Brother Niu, you still say that people are stupid, but you are the old man!" ”

Niu Laosan glanced at him unconvinced: "Brother Huang, my old cow is stupid, you are not stupid, you continue to work, what does this have to do with moths?" If you can break it out, my old cow will kowtow to you three times now, and worship you as a teacher! ”

This......

Huang Cunzheng was speechless by him, this problem was not solved by them at all, and the two had to look at Li Qingshan again.

Li Qingshan said with a smile: "Everyone must have seen a moth fighting a fire, but has anyone ever wondered why a moth fights a fire and is not afraid of death?" ”

Niu Laosan and Huang Cun glanced at each other, and then shook them again, saying that this question was really beyond the scope of their knowledge.

“…… In fact, this point has long been recorded in ancient books, and all insects like light and dislike darkness in eight out of ten. Just as people in the world like warmth and avoid cold, this is the instinct of living beings, and the book calls this habit of insects phototaxis. ”

"Phototaxis?"

Huang Cunzheng and Niu Laosan looked at each other at first, but after thinking about it carefully, both of them couldn't help nodding their heads.

The moth went to the fire and burned himself, almost no one could understand the reason, and Li Qingshan's explanation seemed to make some sense, at least it could be explained.

"No wonder," Niu Laosan nodded while thinking, "If the termites are together at night, just put out the candle, and the termites will go to other places where there is a bright light." I've heard my father talk about this method since I was a child, and I've tried it myself, and it does work wonders, but I can't figure out why it's like this. I just heard the little brother say this, it seems that this is phototaxis, there is really such a thing! ”

Huang Cunzheng looked thoughtful, "...... No wonder you want to wrap this horse in that strange shape, the old man thought that this was necessary to dance the god to exorcise evil spirits, it turned out - it was not! ”

Li Qingshan nodded at him and said, "Uncle Huang, I really wasn't dancing any great god just now, but I took advantage of the phototaxis of insects. The bug probably got into the horse's ears by mistake. Everyone in the world knows the length of the horse's face, but they don't know that their ear holes are also very deep, and the insects lose their direction for a while, burrowing deeper and deeper, and falling into the darkness and unable to escape, they can only crawl and bump around. ”

"There are sensitive nerves in the ear holes, there is a bug in the rampant inside, the horse is naturally very painful, itchy and unbearable, so it will shake its head hard, trying to throw the worm out, but unfortunately the horse's ears are too deep, the worm is a light thing, can not withstand the force, so no matter how hard the horse shakes its head, it is difficult to throw it out."

Niu Laosan also nodded frequently: "Since you can't get rid of it, you can only think of other ways......

Li Qingshan pointed to the black cloth that fell to the ground and said: "I first use this black cloth to cover the horse's ears, that is, to create a completely black external environment first, and then use the lenses to reflect the sunlight and shine directly on the horse's ears." There was darkness around the bugs, and suddenly a bright light appeared, and out of the instinct of phototaxis, the bugs would definitely crawl towards the light source......"

Hearing this, Huang Cunzheng suddenly slapped his thigh, looking suddenly realized, Niu Laosan asked, "What's wrong, do you understand?" ”

Huang Cunzheng replied with a smug face: "Of course I understand." Although this worm is the culprit, it is also extremely pitiful, trapped in it and does not see the light of day. When the baby helps the insects escape, the problem of the big yellow horse will be solved...... Baby, you're right? ”

"It seems that Uncle Huang does understand," Li Qingshan cast a beam of approving gaze, "This whole thing, to put it bluntly, is how to guide a lost little insect to see the light of day." As for the prescription prescribed by Lao Lang, although the medicinal juice made of those medicinal herbs can suffocate the worm in the horse's ear, the medicinal juice will inevitably damage the horse's ear, and the medicinal juice and the body of the insect are difficult to discharge in the horse's ear, which will cause more lasting damage, so I will say that the recipe is more than worth the loss......"

Li Qingshan's explanation was simple and simple, not only analyzing the cause clearly, but also comparing the principles, pros and cons of the prescription prescribed by Lao Lang and the methods he used.

Niu Laosan and Huang Cunzheng were both greatly impressed, and they could still be treated like this, it was really evil, and even Tang'er, who was playing with the horses under the bamboo shed, was fascinated for a while, and was stunned next to the big yellow horse, with such an expression.

It turns out that this wicked man's seemingly weird and funny insect repellent Dafa just now is actually based on such a principle.

In addition to being surprised, Huang Cunzheng suddenly asked, "Baby, where did you learn these strange things?" ”

Li Qingshan had expected him to ask such a question, but fortunately he had prepared some words early, but before he could speak, Niu Laosan next to him had already shouted first, "I know, I know!" ”

Li Qingshan was a little surprised, glanced at Niu Laosan, and motioned for him to continue.

Niu Laosan patted Huang Cunzheng on the shoulder: "Brother, you don't know, this baby in your village likes to study these strange insects, this morning, you didn't see him staring at those two bamboo ...... What kind of insect does bamboo come from......"

"Stick bugs." Li Qingshan prompted.

"Yes, stick insects," remembering the situation in the morning, Niu Laosan was still impressed, "You didn't see the obsessive look of him staring at the two stick insects, as if he had been immobilized, motionless." If it weren't for the second lady to scare him, I was afraid that the little brother would be able to stand until the sun went down! ”

Speaking of this stubble, Li Qingshan scratched his head and looked ashamed, "Uncle Niu, I was observing them at the time...... Seventy-nine days, it's a biological miracle, and I just thought that if I could last 79 minutes, it would be awesome...... As for the obsession you are talking about, I can't talk about that. ”

"What the hell is Fork Fork Ouou?" Huang Cunzheng heard it strangely, and couldn't help but say something.

Niu Laosan was a little embarrassed: "I don't understand this, I just remember to be happy, playing, or something...... Brother Huang, if you really want to find out, you still have to ask this baby in your village. ”

Li Qingshan looked up at the sky, a little helpless. If you want to explain xxoo, you have to talk about Stephen Chow, and you have to talk about "The Judge of the Dead", then at least you have to explain what a movie is. To explain a movie, at least make it clear what electricity is......

Mom, this project is too big.

When she was in distress, Tang'er's impatient voice came from behind: "Stinky boy, this girl just listened to you explain what phototaxis, didn't she explain it to the head?" ”

Li Qingshan looked back and saw that Tang'er had already untied the horse's reins and led the horse out from under the bamboo shed.

"And the previous stick insects, reincarnate, fermentation or something...... It's all weird stuff you've never heard of, don't you explain it well, why can't you explain it now? ”

Explain in front of a big girl what is a fork Ouou, this ...... It's really a bit difficult, Li Qingshan scratched his head and sighed helplessly, "Miss Tang'er, this ...... It's really hard to explain, why don't you let me go? ”

The girl glared at him: "It's better to explain than to demonstrate." Since it's hard to explain verbally, won't you demonstrate it? ”

At this time, Li Qingshan was completely speechless.

If I were to demonstrate this in front of you, you would have to slaughter me, or in pieces......
