I collect cultural relics in the human world

Chapter 56: The mountain of swords and the sea ([-])
When Fan Yu and Jiang Huai were fighting in full swing, He Si and Qin Jian were already sitting on the rugged rocks, enjoying their leisurely time without being disturbed by anything else.

It's like exploring a long and narrow dream, breathing in the light pink water vapor, and wandering in the ink-smeared landscape. This is a unique and subtle feeling, terrifying and sweet.

"Did you come from a long time ago?"

Qin Jian nodded lightly and did not take He Si's words.

There must be something hidden that cannot be told, He Si thought, not annoyed.She usually doesn't like to force others to use herself to save others. When the time comes, all mysteries will be solved.So he smiled and brought the topic to a sigh-like ending: "So it is inevitable that you are not good at math."

"Why do you say that?"

"Our ancient literature and history are developed, but mathematics is very backward."

Qin Jian, who is not as handsome as a mortal, raised his eyebrows slightly, and there was a trace of evil on his dark and intertwined face: "Gou Guang three, Gu Xiu four, Jing Yu five, this conversation between Duke Zhou and the doctor Shang Gao, as far as I know, is The world’s earliest record of the Pythagorean Theorem.”

He Si quickly added: "What I mean is that ancient Chinese mathematics deviated from the imperial examination system and the ruling class. Naturally, it also deviated from scholars. No one studied and studied, so it would lead to slow development."

"It is indeed influential," Qin Jian did not deny it, "but we cannot ignore those classics, such as Zhou Bi Suan Sutra, New Fa Suan Shu, Calendar Complete Book, Wu Cao Suan Sutra, Jiu Zhang Su Shu, Sun Tzu Suan Sutra, and Shu Shu Ji Yi … This is our continuous academic thread.”

"I've heard of these too," He Si pursed her lips, remembering the calculations related to ancient architecture, and said, "It's just that these books are mainly about calculations, more like some kind of arithmetic problem books or calculation example books, but they just draw the conclusions As a result, no consistent theorem was produced.”

"This only shows that practicality is the premise of ancient Chinese mathematics research," Qin Jian obviously did not agree with He Si's statement. "Putting what you have learned into practice. Our ancestors valued practice and did not like doing science for the sake of science. Is there anything wrong with that?"

"I-I didn't mean that."

"I know, I just don't want to damage the impression of ancient mathematics in your mind just because I am not good at mathematics." Qin Jian smiled slightly, and the topic relaxed again. His eyes shimmered when he looked deep into the cave. "As for the debate between Chinese and foreign mathematics, you may want to ask Jiang Huai. As for the mathematics I have seen, the larger ones can communicate with the gods and follow life and fate, while the smaller ones can manage worldly affairs and resemble all things. That is the real mathematics."

"Hey, simple, too simple."

Just when Qin Jian was vindicating the name of ancient Chinese mathematics, Jiang Huai also solved the third Sudoku game. When he was feeling complacent, he sneezed inexplicably.

"Brother Fan must be impatient to wait for me." He thought, refocused his energy, and waited for new questions to appear.

But this time, the door did not turn into quicksand in front of him, but was actually opened, revealing the magnificent festive furnishings in the house.

"This is this?" Jiang Huai poked his head inside and saw no one, but he saw three tables lined up in a row. The tables were all covered with red cloth very elegantly, and old objects were neatly placed.

Before he could take a closer look, a soft voice came to his ears: "Please prepare three gifts for the bride."

The voice sounded more real than before, as if it was close to the back of his head. Jiang Huai couldn't help but turn around and saw a face hanging upside down from the ceiling. The pale face made the lip color even more gorgeous, and he was looking at her affectionately. Look at him.

"Oh my god!" Jiang Huai's hair stood up and he ran into the door without hesitation.With a bang, the door closed behind him.

Jiang Huai scanned the ceiling with lingering fear, making sure that there were no faces left, and then walked to the table on the far left with trepidation.

There are three jars of wine from large to small on the table. There are traces of loess staining on the wine jars. It looks like daughter's red wine that has been dusty for many years, but it has been opened at this moment, and the aroma of the wine is overflowing.Jiang Huai looked carefully into the mouth of the jar and saw that the three jars still had the same amount of wine left, and he immediately made a guess about the topic.

"Please prepare the Henan wine for the bride's bridal night."

The voice just sounded, and Jiang Huai, who was thinking, subconsciously shrank his neck, and instantly got goosebumps all over his body.

The owner of the voice was very satisfied with Jiang Huai's performance. He chuckled and then said: "The first wine jar has a capacity of eight liters, and three liters were consumed. The second wine jar has a capacity of five liters. Now there are three liters left. The third wine jar has a capacity of three liters, but only two-thirds of the wine is left. Please take one liter of wine to meet the bride."

"This bride is really good at drinking." When Jiang Huai heard the question, most of the shadow on the face had dissipated. He controlled himself not to turn his head, focused all his attention on the wine jar in front of him, and immediately started to answer the question. .

Without hesitation, he directly picked up the first wine jar, walked to the third wine jar, and filled the third wine jar with a loud splash.Then put down the first wine jar, pick up the smallest wine jar that was just filled, go to the second wine jar, repeat the previous operation, fill the second wine jar again, and then fill the smallest wine jar Put it back on the table.

After completing this series of operations, Jiang Huai clapped his hands and said calmly: "Okay, there is exactly one liter of wine in the No. [-] wine jar."

"Please move."

Jiang Huai shook off the soft and tiring female body in his ears and immediately walked towards the second wooden table.This time there were two hourglasses on the wooden table, still different sizes, representing different times. There was a bowl next to it, which contained a light brown unknown liquid, which looked very abnormal.

But when he saw the hourglass, Jiang Huai knew something.

"Please help the bride warm up a pot of sobering soup. One minute more is too much, one minute less is not enough. It should be warmed for 9 minutes, no more, no less."

"Hey, she seems to be a young lady from a wealthy family. If you're afraid of getting drunk, just drink less."

The complaints did not affect Jiang Huai's answer. He first looked at the two hourglasses, one said 7 minutes and the other said 4 minutes. He calculated silently in his mind for a while, 4+3+1+1, and he was sure. Immediately put the decanting soup rack on the stove and at the same time turn the two hourglasses upside down.

The sand flowed very fast but very slowly. Jiang Huai didn't even dare to blink. He silently recited the number combinations in his mind while staring at the hourglass, for fear of missing the timing of the conversion.

The 4-minute hourglass had run out. He immediately turned the hourglass over and started the timing again.

At this moment, the 7-minute hourglass still had 3 minutes left. After the 3 minutes passed, Jiang Huai turned the drained hourglass upside down and began to pay attention to the small hourglass with 1 minute left.

I still need two more 1 minutes, Jiang Huai thought silently in his heart, these two 1 minutes will be brewing at the same time.

The first minute comes from the small hourglass, and in the process of consuming this one minute, another minute has been formed in the big hourglass.So when the sand in the small hourglass disappeared, Jiang Huai turned the big hourglass over again.

finished.

Nine minutes seemed like a long year to Jiang Huai. He picked up the hangover soup and put it on the tray. He didn't want to stay in front of this table for a moment. He came immediately without waiting for the terrible female voice to announce. In front of the last table.

This time there are seven identical camphor wood boxes on the table, engraved with peonies in relief. The carvings are exquisite and detailed, like ancient women's dressing boxes.The aged camphor exuded the faint fragrance of vegetation, which reminded Jiang Huai of the figure of the old Chaofeng. His excitement and anxiety after answering two questions in a row gradually calmed down.

"Open it."

After receiving the instruction, Jiang Huai took a deep breath and opened the boxes one by one, and found that each box contained many identical golden beans.

What does it mean?He frowned, unlike the last two times. He looked at the seven boxes and the shining golden objects inside, his mind went blank, and he suddenly felt helpless.

"Since I'm going to meet the bride, I can't go empty-handed. Of these seven boxes of golden beans, only four are real. The real golden beans weigh 10 grams each, while the fake ones only weigh 9 grams. Find out the real ones Four boxes, take them to your bride."

"Is this... a test of my hand skills?" "Look at my memory," the voice smiled, "I was so absorbed in watching you solve the problem just now that I forgot there was a scale, but I have to remind you, this It’s a scale that can only be used once.”

As soon as he finished speaking, a wooden balance, a beam, two scales, and many fragmentary weights appeared on the wooden table covered with red cloth in front of Jiang Huai.The balance is teetering on the edge, and it looks like it can only be used once.

Jiang Huai cried out in his heart.

There was a kind of unbearable regret in the examination room, which was called "I have seen this question before," and he felt this kind of regret now, and it was still a fatal regret.

If I could start my life over again, I would definitely read that question ten times. Unfortunately, my life is coming to an end now, and I don’t even have a scratch paper.

In desperation, Jiang Huai ran to the first table, picked up a wine jar, smashed it on the ground, picked up a handy fragment, and began to calculate.

This balance can only be used once, and the method of grouping several boxes to compare left and right will definitely not be used, so - maybe you can take some golden beans out of the box.

Assuming that the golden beans are all 10 grams, then the theoretical weight of the golden beans I took out will be there, but because there are fake ones, the actual weight and the theoretical weight are of course inconsistent.The theoretical weight minus the actual weight is the number of fake golden beans, so——

Jiang Huai murmured to himself, feeling that the answer was already coming out. What is the use of knowing the number of fake golden beans among the golden beans taken out? Can it be located on the corresponding box?
How to ensure uniqueness?

correct!I just need to ensure that the sum of the quantities taken out of each three boxes does not repeat...

Jiang Huai's eyes lit up.

他放过了第一个盒子，然后依次从第二至第七个盒子里拿了1、2、4、7、13和24粒金豆子出来，将这51粒金豆子一起放到了天平上。

Theoretically, the weight of 51 golden beans should be 510 grams, but Jiang Huai counted the weights and found a total of 490 grams, which meant that 20 golden beans were fake.

The scale quickly decayed the moment Jiang Huai measured the weight. He looked at his draft again. Among these numbers, 20 can only be the sum of 0, 7, and 13. Therefore, the first, fifth, and fourth The contents of six boxes are fake.

Jiang Huai smiled with relief, and the gift was picked out, and then.

Of course the female voice wouldn't keep him waiting any longer, as the voice got farther and farther away.Jiang Huai turned around, but the surrounding walls remained unchanged, but the closed door behind him bounced open again.

"Go inside, your bride is waiting for you."

Are you going to see Fan Yu?After answering so many questions, Jiang Huai felt a strange expectation in his heart.

Hearing a noise near the door, Fan Yu also raised his head at this moment, as if he had a telepathic connection.

The two people's gazes were anxiously together. From vigilance, testing, to recognition, reunion, and joy, they became inseparable in an instant.

"Lang Jun, you are here!"

Fan Yu's voice seemed to leak out from between his teeth.It turned out that he was struggling with a pair of remaining withered claws, holding the claws in one hand and holding a red rope in the other. The red rope tied his trophies tightly, and he bit the other end in his mouth.

Due to the battle just now, the house was in a mess, and everything was beaten to pieces.There was still mucus on Fan Yu's face, and his bright red wedding dress was as torn as rags.After confirming that Jiang Huai was outside the door, he lowered his head and began to sort out his trophies.

Jiang Huai looked in through the half-open door and saw such a scene. He instantly felt that his expectations were all gone.

"Is this a martial arts fight?"

"It wasn't supposed to be so intense. Who knew someone had to solve the problem for three hours? What, is it a Nobel mathematics problem?"

"There is no Nobel Prize in mathematics." Jiang Huai stepped into the door, stepped on the yellow and gray ground with some disgust, and said angrily.

This was indeed beyond Fan Yu's cognitive scope. The choked man decided to find something to vent his anger.

"Don't move, if you move again I'll chop you!" He took out the dagger hanging from his waist, quickly flipped it between his fingers for a round, and then pressed it back to his waist. The pair of withered hands actually became quiet. No more struggling.Fan Yu quickly picked up the only intact piece of fabric in the room, the red hijab, and wrapped the trophy thoroughly.

"What is this?" Jiang Huai obviously looked at the withered hands and sharp fingertips, and asked without knowing why.

"A gift for Dr. Guan." Fan Yu answered as he should.

"Can it really be taken out?" Jiang Huai also became curious.

"Try it." Fan Yu finished his work and returned to his room, "By the way, what question did you answer just now?"

There are too many, Jiang Huai thought, and decided to start with his favorite Luoshu: "Fill the numbers from one to ninety-nine into the Jiugong grid."

"It's so simple!" Fan Yu jumped up from the bed, "I have studied this question, but it was wasted."

"That's true," Jiang Huai thought of Fan Yu's business and should know Luo Shu well, and flattered him quickly, "Brother Fan also has a lot of experience in Luo Shu. I will ask Fan Yu for advice someday."

"Looking for advice from Luo Shu?" Fan Yu waved his hand, "Haven't you ever seen The Legend of the Condor Heroes? Does Yinggu know, my sister Rong?"

"The Legend of the Condor Heroes? Isn't this a question of number combination in Luo Shu?"

Fan Yu's head got dizzy when he heard the numbers, and his hands almost caught up with the propeller: "What number combinations are not combined? The nine numbers are arranged diagonally, up and down are interchanged, left and right are interchanged, and the four dimensions come out, right?"

"Brother Fan is really good at both civil and military skills." Jiang Huai thought to himself that this man was still hiding his secrets, and nodded quickly.

"Have you been doing this for so long?"

"No, there are also fourth-order magic squares, Sudoku, some probability questions and situational questions later."

Fan Yu looked at Jiang Huai's serious return and made sure he was not talking nonsense. He stepped forward and patted him on the shoulder: "Your dream is really perverted."

Indeed, Jiang Huai nodded guiltily as he looked at the mucus all over the floor and the still wriggling severed fingers.

"I won't dare in the future."
