I collect cultural relics in the human world

Chapter 54
"Mathematical question?" Fan Yu's expression was as if he had eaten a fly and he was hesitant. He thought for a while and then said in a threatening tone, "He Si, tell me the truth. Don't forget that we are already comrades-in-arms. ”

He Si spread her hands, she really didn't know that after passing the barrier, she and Qin Jian were not in the same dungeon.It does look like a martial arts fight from her side, but who knows about Lao Chaofeng.

However, she still replied with an innocent face under Fan Yu's earnest gaze: "I think it's true. Why would Mr. Qin lie to you? He must be expecting the effect of your women's clothing."

As soon as these words came out, even Jiang Huai choked.

"Math problem!" Fan Yu continued to repeat, but shook his head and said, "Uncle Qin, listen to it for yourself, this is too ridiculous. When did you learn to lie?"

"Yeah, when did I learn to lie?" Lao Chaofeng stood calmly with his hands behind his back.

Fan Yu's face turned from green to red, and he asked persistently: "Tell me, what did he ask when he broke through the barrier?"

"Mathematical probability question. It's a long question. Are you sure you want to listen?"

Fan Yu's face turned from red to green again, but this time he gave up the struggle and resignedly picked up the bride's red wedding dress. While putting it on with all his strength, he sighed: "People's hearts are not ancient, and the world is dripping with water." , A great reputation for a lifetime will not be guaranteed in the later years, hey. You said that my literary talent is not a test of poetry and poetry? "

Seeing that the dejected Fan Yu could continue to talk nonsense, He Si found it amusing and couldn't help but say: "You are born to be useful, Brother Fan, there is a chance."

Fan Yu's eyes lit up and he felt much brighter. He boasted, "Hey, Xiao He has made great progress recently and has become more knowledgeable."

Qin Jian's face darkened, thinking that he really couldn't let He Si and Fan Yu have any more contact.

In just a few words, Fan Yu had already put on the red wedding dress.

Thanks to the long wedding dresses in ancient times that trailed to the floor and had long sleeves, Fan Yu's 1.9-meter-tall figure actually fit into it, except for the bulges at the shoulders. The long dress that was supposed to cover the three-inch golden lotus only reached the calf, and the layer The layered skirt paired with a pair of water-soaked kicks couldn't be more exquisite and beautiful.The plackets of the wedding dress were difficult to hold together, and it was absolutely impossible to put on the gloves, so Fan Yu simply wrapped them around his forearms to make weapons.

Although it doesn't look like anything fishy at first glance, when you take a closer look, you can see that a wedding dress worn by Fan Yu shows the heroic spirit of a soldier on the battlefield.

"How's it going, sister Xiao He?" Fan Yu was still proud and raised half of his eyebrows proudly.

"Fan Chu's plasticity is quite high." Lao Chaofeng took a step forward, "But there is still something missing."

"Ah, I know," Fan Yu picked up the phoenix crown on the table and pressed it on his head, "Feng Guan Xia Pei, I haven't put on the phoenix crown yet."

"The phoenix crown can't cover your face, so you'd better use this." As soon as he finished speaking, a piece of red cloth jumped out of the air from the wooden table and hit Fan Yu's face, covering his extremely decent thick eyebrows and big eyes. .

"Ahem, it's too gray." Fan Yu coughed and clapped his hands.

"It's indeed much better now." Seeing this, He Si couldn't help but curl her lips towards Lao Chaofeng.

"Brother Jiang Huai, I'm already like this, how are you preparing?"

"Hey, I, I'll be ready soon." Jiang Huai looked at Fan Yu, who was like a thick wooden stake, and didn't dare to laugh, and quickly put on the groom's red wedding dress.He has red lips and white teeth, is young and handsome, otherwise he would not be able to stand out among the newcomers in the entertainment industry who are showing off their magical powers.Wearing the wedding dress that seemed to be tailor-made for him, even He Si couldn't help but take another look at him.

"I'm ready." After he finished dressing up, he walked to Fan Yu in small steps. He didn't know whether he should support the bride whose sight was obscured.

"Then let's go." Fan Yu didn't need to worry about him and hurriedly rushed into the barrier.

"and many more!"

This time, Fan Yu was stopped by Jiang Huai.

"One rush, then another failure, three times all. Tell yourselves, how many times have you waited tonight? Can it be finished?" Fan Yu scratched his head in a frenzy, but his fingers were stuck on his head. Guan blocked it, and the whole person became even more irritable.

"I mainly want to ask what the so-called mathematical probability problem is, and whether it is the same as I imagined. After all, I have to answer a question later."

"Why do you think there are so many probability problems in your imagination? That's right, this is your dream..." Fan Yu muttered, getting angry again, "What kind of bad idea do you have, asking someone to solve equations in a dream? "

"I...I graduated from the Mathematics Department of Western University."

After saying that, even Lao Chaofeng looked at Jiang Huai with awe in his eyes. Fan Yu lifted up his red hijab with a look of disbelief on his face.

"A top student...how did you end up in this...well," Fan Yu compiled his sentences and said, "How could such a pure professional end up in such a complicated entertainment industry?"

"Because it's quite profitable." Jiang Huai looked shy but spoke in a matter-of-fact tone.

Fan Yu gave a thumbs up: "As expected of a math major, he can calculate taxes clearly."

Jiang Huai knew what he meant, but there were too many opportunistic attempts among his colleagues, so he didn't want to say more, so he simply urged: "Brother Fan said that we should fight quickly, let's go."

"Wait." This time, it was Fan Yu himself who stopped the action.

Jiang Huai thought he was involved in a tax issue, but Fan Yu actually shook his head and looked at Lao Chaofeng.

"No, Uncle Qin, your mathematics must still be at the ancient stage, right?"

Lao Chaofeng remained silent, and Fan Yu became even more suspicious: "You can't really be coveting my women, right?"

"After entering the barrier, I saw three rooms and three closed doors. A voice told me that Miss He was sitting behind one of the doors, and the rest were Miss He's parts. The voice asked me to choose one. Door."

"Three questions?" Jiang Huai's urgent voice broke Lao Chaofeng's statement.

"One-third, why does such a simple question have a proper noun?" Fan Yu looked at his nondescript red wedding dress and said sadly, "I was deceived again. I can also do this question."

"That's not it. There is a second half to this question," Jiang Huai said after seeing Lao Chaofeng nodding to him. "The voice will ask Mr. Qin to choose a door first, but he will not open this door. Instead, open one of the other two doors to reveal...well, Miss He's parts."

"It should be an illusion of a stump." He Si added, sounding awkward.

"Yes, yes, then the voice will ask Mr. Qin if he should change the door. In other words, will changing the door increase the probability of Miss He appearing behind the door."

"Of course I won't change it. When the King of Heaven comes, it will be one-third!" Fan Yu replied firmly.

"Then Miss He has really become a component."

"Should...should the door be changed?" Fan Yu looked incredulous, "What is the principle of this!"

"Because the voice can and can only open the door with the illusion of residual limbs, it helps us eliminate some possibilities. For example, Mr. Qin chose Illusion One for the first time, so the voice can only choose Illusion Two..."

"Stop it!" Fan Yu looked like he had a headache, "Is this question famous?"

"The Monty Hall Paradox is a very classic and very confusing probability problem. It is famous because it goes against intuition, but in fact it can be solved if you think about it carefully."

Can it be solved? !
Fan Yu felt insulted again. This time he turned around angrily and disappeared into the barrier without giving the other three a chance to say "wait a minute."

"Then I'll go too." After learning the type of problem he was going to face, Jiang Huai felt much more relaxed and walked into the unknown with light steps and almost a smile on his face.

"They just disappeared out of thin air." He Si looked at the direction in which the two disappeared, as if sighing or stating.

"Sit down for a while, you need to be good at it." Lao Chaofeng pointed to the chair in front of the wooden table.

He Si turned around and saw that Lao Chaofeng behind her was still looking calm and solemn, so she couldn't get angry. Naturally, she didn't dare to say joking words. She was full of questions and didn't know where to start. She suddenly looked forward to the man in the happy dress. The young man who is convinced is here. "Ah Si, you must have missed me."

Looking back, the person behind him is already the Qin Jian who just appeared in his mind.

He Si pursed her lips and finally plucked up the courage to ask, "Who are you?"

"What do you think, Ah Si?"

In fact, she should have asked this question downstairs in the dormitory that day, but she couldn't open her mouth.But at this moment, He Si had already made a calculation in her heart. Whether it was the old Chaofeng or the young man, it was all Qin Jian.All she needed was the last confirmation - a nod from herself.

"Of course you are Qin Jian, but I don't know which one is the real you and which one is my illusion."

"Asi hopes which one is the real me."

He Si lowered her head to hide her blushing face, but immediately raised her head again. She wanted to completely resolve this ever-changing illusion, so she mustered up the courage to look at the young man in front of her with clear eyes, who seemed both good and evil. : "Now this."

The sound was like mosquitoes and ants, but Qin Jian still heard it.He lowered his eyes, but couldn't hide the smile in his eyes.

"That's what it is now."

"But Fan Yu and the others?"

"This world is full of things that everyone turns a blind eye to." Xiao Langjun said what Lao Chaofeng once said to her, but it didn't sound inconsistent at this moment.

He Si immediately accepted this statement and asked about the next step: "Then what should I call you in the future?"

"Since this is my real body, please call me Qin Jian at this time. Normally, you can call me Lao Chaofeng or Lao Sir."

He Si nodded obediently.

The two of them had only been together for a few days, but they already knew each other very well, and their hearts were clear.Especially He Si, who doesn't talk much to begin with, a conversation that should have been extremely tense disappeared without a trace. The two of them just clicked and stopped looking at each other, avoiding each other's gaze.

The sudden silence covered He Si layer by layer.

Rock water is still dripping, meandering along the stalactites and creating circles of ripples in the deep and shallow pools.He Si seemed to hear the sound of a water lily blooming, the petals bursting gently in the water vapor, and it ended just right.

He Si thought that whether in her sleep or when she invaded the Mirror Realm not long ago, she had not been able to take a serious look at this cave.Now that she had nothing to do, and with Qin Jian's breath beside her again, she could simply enjoy the spooky, steep and spooky cave with its scattered rocks.

Unlike the scenic caves she had visited, each stalactite was illuminated by colored lights, and the various stone pillars looked dazzling against the colorful neon lights.There are only two crumbling red lanterns hanging in front of the simple wedding house, making the holes and stone pillars formed by the long-term erosion of groundwater glow with a shadowy red light, making it even darker and more confusing, and making Qin Jian's slender figure even more mysterious. dream.

"You're really not good at math." After a while, He Si suddenly said something out of nowhere.

"How do you say this?" Although Qin Jian has regained his youthful appearance, he still has the habit of speaking in an old-fashioned way.

"I've been waiting for you behind the door for a long time."

"Huh." Qin Jian was silent for a moment, then realized what He Si meant, "I'm really not good at math, and this level wasn't calculated by calculation."

"That is?"

"Since he asked me this question, naturally it shouldn't be an answer that everyone can think of, so he had to change the door."

"So simple? Then shouldn't you be in my room early in the morning?"

"Of course not, this is the first level of planning," Qin Jian raised his eyebrows, "Anyone with some cleverness can predict it, and the person who asked the question should naturally predict it."

"So it's still the same?"

"No, this is the second level of planning, to guard against smart people."

"Then...or change?"

"People's thinking always has its limits, and the layers are layered over and over again. People who don't think carefully and have insufficient concentration will lose their way here."

"So it doesn't change?"

"Thinking too much is also a shortcoming. You must not calculate too much, which will eventually lead to indecision, self-restraint, and hesitation. As the saying goes, great wisdom is like foolishness. Thinking about this, I returned to the first level."

He Si became anxious after hearing this and asked: "Will it change or not?"

"Hey, so the hardest thing to predict is the human heart. Anyway, I kept Ah Si waiting for a long time."

He was obviously self-examination, but Qin Jian showed a look of grievance on his face. For such a high-minded person, his always cold eyes showed the wet look of a puppy. He Si almost couldn't control it, and quickly turned away, confused. He said: "So if you learn mathematics, physics and chemistry well, you will not be afraid of traveling all over the world."

"Asi still blames me after all."

"I don't have one. The so-called specialization in the arts, but your literary and historical skills are beyond the reach of everyone." He Si didn't dare to look at Qin Jian, who was addicted to acting. His eyes flickered, and he suddenly noticed the stone wall surrounding them. , and thought of the small stone I had just mentioned in the courtyard of the castle.

After Fan Yu said the name, Jiang Huai seemed to ask about it, but Qin Jian changed the topic.He Si didn't know if Qin Jian simply wanted to speed up the pace of exploration, or if he wanted to avoid Jiang Huai, or if he just couldn't talk or didn't want to talk.So even though she was curious, she held back and didn't speak.

"Look at that stalactite," Qin Jian seemed to have read through her mind. He pointed at an upside-down stalactite on the top of the rock wall in front of He Si and asked, "Does it look like a little lion?"

"Eh? Yeah." He Si didn't expect Qin Jian to take the initiative to lift the stone and nodded hurriedly.

"A little stone is a little lion."

"Is he a lion?"

"Haha," Qin Jian looked at He Si's wide eyes and found it very interesting. He chuckled twice and uttered two more words, "Suanni."

"That Suani who gave birth to nine sons from a dragon?" He Si's eyes widened even more - the ninth son from a dragon, ranked fifth, looks like a lion - how is this possible?

"Your literary and historical skills are not bad either."

The words she just said to comfort people were applied to herself again, and He Si was speechless for a moment.

"But there are indeed many things to study in ancient architecture." Qin Jian added without waiting for her answer.

He Si thought again of the stone lion she saw at the door of Lao Chaofeng's room on that first day in the hotel. It was cute and exquisite.When she left, she saw it stretching, blinking and smiling at herself - she thought it was an illusion at the time, but now it seems that she saw the true nature of the little stone at that moment.

It was also on that day that she saw Qin Jian's true appearance - that handsome and interesting man who brewed a pot of tea with ease and style.

In this case, what she experienced that day was not an illusion, so where did that moist, sticky and slow touch that licked her ear come from?

　Although the full text is based on cultural relics, during the process of searching for information, I found that there are so many things worth writing about in ancient times. In the next chapter, we will talk about some interesting stories about ancient Chinese mathematics. (There will also be topics on ancient architecture and drool-worthy food later)
