Time seemed to stop abruptly, the occasional breeze suddenly disappeared, the sun was still blazing, the sky was blue and cloudless, there was not a trace of sound around, quiet and eerie. Dong Banxian's face was calm, occasionally, his brows would jump inadvertently, Xiaolu's grandfather smacked his lips and wanted to say something, but he never said it, Zhou Ying's eyes widened, his face was pale, Xiaolu held Zhang Hui's arm tightly, his body shook from time to time, Zhang Hui and Sun Hao were better, but they were also incredible, Lu Xue's brows were deeply locked, and he couldn't see what he was thinking, the most excited thing here was the middle-aged man, I saw his eyes shining, looking at Dong Banxian excitedly, in his eyes Dong Banxian was no longer half an immortal, but a full immortal.

Dong Banxian returned to his residence proudly surrounded by everyone, and said some sales words that he didn't understand, and the middle-aged big money said yes again and again, Sun Hao saw that we were not too excited, and it was not good to be too flattering, just smiled and nodded in response. In the end, the middle-aged man spent a lot of money and bought a lot of charms, and when he left, he was very satisfied with his appearance.

"Is there anything else going on?" Dong Banxian glanced at us angrily, and his tone was low.

Sun Hao hurriedly smiled and said, "Half Immortal, don't worry about our children, don't worry about our children, we are not young and have shallow experience, you have a lot of adults, so don't worry about us." ”

"And what else do you have?" The half-blind began to drag on again.

"That, that, we want to get a few spells back, too."

Dong Banxian was silent for a while, and sighed, "Originally, you desecrated the foundation of your ancestors, and you can't bless you, but God has the virtue of a good life, that's it, that's it" Then he took out a bunch of charms, and said, "What kind of charms do you want?" ”

"I don't want to recruit rats." Xiaolu said with some trembling.

Everyone nodded in agreement.

"There is no prayer, that is"

"Well, this." Half-blind didn't wait for Sun Hao to finish speaking, he picked up a talisman casually, "This blessing has an outstanding effect, it was carved after seven full moon hours, I originally wanted to leave it to my grandson, hey, see that you sincerely want it, and it was brought by the old village chief, I will charge you a cost of work, two thousand." ”

Sun Hao took out the money with some pain and asked for the charm back.

"Young man, I have a charm here to pray for a happy marriage, seeing that you are the quasi-grandson-in-law of the old village chief, I will also charge you a cost of work, one thousand and five, and give it to you." Dong Banxian looked at Zhang Hui and said, and then sighed a little reluctantly.

Zhang Hui saw Xiaolu's look of hope, and took out his wallet with an ugly face.

"Little girl, what do you want?" Dong Banxian turned to Zhou Ying.

"Ah, I don't want anything."

"I have here a charm for the face, which was carved by the noon hour when the two peach blossoms bloom, which suits you very well." Dong Banxian said with his eyes half closed.

"This one has the same effect as the one that lures mice?" I asked, half-blind and opened his eyes to look at me intently, then at Xiaolu's grandfather, and nodded slowly. "This spell is for young women, and it won't have any effect if you hold it, but if you really want to ask for it, five thousand."

I nodded and asked, "Is it also useful for women over forty?" ”

"Of course, of course."

"Can they not grow old again?"

"Well, ah, of course not." Dong Banxian was silent for a moment and replied.

"So if its utility will be halved, then its value should also be halved."

Dong Banxian was silent for a while, and nodded with difficulty, "Okay, two thousand five." ”

"So who can get the best results with it?" I asked again.

"Of course, it's a young woman between eighteen and twenty-eight, and this is a cherished charm that can slow down aging." Dong Banxian said dissatisfied.

"Oh, that's two-thirds of its effective utility."

"This, this, well, a thousand, it can't be any lower."

"Does it remove scars?"

"Of course, no."

"The utility is limited."

"Okay, five hundred."

"Is it easy to keep?"

"Of course, you can hang it on your body with a talisman bag."

"Do you burn it?"

"No, you don't." Half-blind and impatient.

"It won't be effective if it's wet."

"No, it won't." Half-waved his hand.

"That is to say, it must be stored and kept with care."

"Two hundred, if you want, take it."

"It's not easy to store, and the effect is similar to that of cosmetics."

"A hundred, here you go."

"Cosmetics can be used over and over again, there is beautiful packaging, and there are beautiful advertising spokespersons."

"Fifty, I'll give you another talisman bag, and then you get out of here." Dong Banxian jumped up and roared angrily.

"Deal"

Everyone""

Everyone left Dong Banxian's house, returned to Xiaolu's grandfather's house, said goodbye to Xiaolu's parents, and embarked on the return journey.

"I didn't expect Xiaoshan to bargain so much?" Zhou Ying sighed.

"I didn't expect that it would be nice if we let Xiaoshan buy all our charms." Zhang Hui nodded in agreement.

"What? Is our happiness worth fifty? Xiaolu was extremely dissatisfied.

"Xiaoshan, what do you think of the mouse?" Sun Hao drove the car, felt that the atmosphere was wrong, and was busy diverting the topic.

I frowned, thought carefully and replied, "I guess it should be that after the spell is burned, it releases an aphrodisiac smell that has an aphrodisiac effect on male mice, and male rats will chase female rats when they are in heat, and at the same time, rats have a long estrus period, so this is why this effect is produced." ”

"Is it possible that the special power of the charm itself is the effect?"

"Well, I don't know, but this phenomenon can be explained by cats."

"Cats?" Xiaolu asked suspiciously, "Have you seen the cat?" ”

Everyone shook their heads inexplicably.

"It's not a living cat, it's dead, ah, it's Schrödinger's cat."

"What kind of Schrödinger is it? Or a dead cat? ”

"Schrödinger is not a breed, it is a man."

"Who? Your relatives? What does he do? Selling cats? I didn't hear you say you still have relatives? Xiaolu continued to ask.

"He's not selling cats, and he's been dead for years."

"A dead man and a dead cat? How can it have anything to do with a group of rats in heat? ”

"Lulu, Hill said Schrödinger was a physicist." Zhang Hui replied helplessly.

"Of course I know who Schrödinger is, but it's funny to see Xiaoshan answer seriously." Xiaolu said with a smile.

The crowd burst into laughter.

"You're becoming more and more like one of us, because you're starting to laugh at me." I looked at Xiaolu and said.

"Xiaoshan, let's talk about what your cat has to do with this group of mice." Sun Hao said.

"It's not my cat, it's Schrödinger's."

The crowd burst into laughter again.

"Schrödinger famously conducted a thought experiment in which a cat was placed in an opaque box and then connected to an experimental device containing a radioactive nucleus and a container containing toxic gases. Imagine that this radioactive nucleus has a 50% chance of decaying within an hour. If decay occurs, it will emit a particle, which will trigger the experimental device to open the container containing the poisonous gas, thus killing the cat. That is, if the box is opened after an hour, the experimenter can only see "decayed nuclei and dead cats" or "non-decayed nuclei and living cats". ”

"Why doesn't he use a camera?" Sun Hao pouted.

"yes, with a camera, isn't everything simple?"

"Well, I mean, uh, let's take this experiment to the next level, with an airtight iron box and an oxygen cylinder in it that lasts for two hours. Opening the crate will also trigger poison gas, so how can you prove when the cat died? And how did he die? ”

"Oh, open the box and do an autopsy."

"Okay, we're adding a bottle of liquid nitrogen, and the gas will be released along with the liquid nitrogen, and the camera's radio waves will also trigger the poison gas."

"Poor cat." Xiaolu sighed.

"That is, when we open the box an hour later, we can only see the dead cat, but we have no way of knowing how it died, which means that we can only see the result, but we cannot reason about the process."

"But what does this have to do with the rats?" Xiaolu asked again.

I continued, "A few days ago, when I was at work, I saw an argument between three people over some trivial matter, and then they quarreled, and they met outside the Internet café to solve the problem. ”

"How did they solve it, did the fight start?"

"I don't know, I didn't go out, but let's make an assumption here, if I were two people, one in the Internet café and one outside the Internet café, and the two of them would see two outcomes without communication, the people outside the Internet café would see two results, fight or not, and on the basis of these two results, I reasoned that I would dissuade them in the Internet café, there would be two guesses, yes or no, that is to say, I saw two different endings outside the Internet café, in this case, I would have four choices in the Internet café, The question is, for me outside the Internet café, does the Internet café have any role in this incident? ”

Everyone looked at each other, and finally Xiaolu asked Zhang Hui softly, "What is he talking about?" ”

"He's saying that we can't guess the whole picture of the process that we can't see when we determine the outcome, and we don't know if there are other factors added to it that cause the situation to change."

"But what does that mean?"

"This shows that it is pointless for us to guess here which elements of the spell attracted the rat swarm, and the more we guess, the more we will magnify the unknown, let us fall into it, and we will not be able to find evidence, and in the end we can only explain the unknown we are facing with the inexplicable elements that we are more willing to believe." Lu Xue said slowly.

Everyone nodded silently.

Zhou Ying thought for a while and said softly, "I once raised hamsters, and there are a few female rats in that rat group, and I can't mistake the smell that the female rat emits when she is in heat." ”

Everyone's breath suddenly suffocated, and they all fell into deep thought.
