When Shi Yuan heard Li Maomao's words, he couldn't help but smile, then reached out and touched Li Maomao's head, and asked, "Little sister, why do you believe so much that your brother will have a way?" ”

"Because...... Because...... I don't know...... That's what I think! Li Maomao looked at Shi Yuan, his eyes were very firm.

Shi Yuan couldn't help but smile slightly when he heard this, lowered his head to Li Maomao and said, "Then little sister, let me tell you, your feelings are not wrong!" With that, he walked over to the buckets that had been rained.

Shi Yuan walked to the side of the pulp barrel, stirred the rough pulp in the barrel with bamboo slices soaked in the pulp barrel, smiled slightly and said secretly in his heart: This so-called rough pulp is to add lime and some alkaline substances to the water, and then soak the peeled bamboo or wood and other materials in it, after cooking, let the fiber of the raw material evacuate, so as to hammer into pulp, and then after the treatment of fine pulp, filter out the finished pulp, put it into the curtain to shape, squeeze off the water, and then uncover it into paper after drying...... This method sounds simple, but it's complicated! Especially after beating the pulp, there are many details and secret recipes in the subsequent process! Although Shi Yuan was also in contact with ancient papermaking when he was studying, it was written in the book after all, and now he came to the scene in person, although the paper he saw was slightly yellowish and a little rough, but he still sincerely admired the wisdom of the ancients!

"Mr. Nangong, since there is rainwater in this slurry barrel, wouldn't it be nice to add some ingredients?" Shi Yuan stirred the slurry bucket and asked Nangong Rong suspiciously.

"To put it simply, the amount of rainwater in these buckets is not the same, and the amount of ingredients to be added is of course different! If only I could know how much water is in each bucket, I'll mix it myself! Nangong Rong explained to Shi Yuan.

"Just waiting for your words!" Shi Yuan was happy in his heart, so he smiled slightly and continued: "Just measure the amount of rainwater in each bucket, is it okay?" ”

"That's right...... Do you have a way? Nangong Rong looked at Shi Yuan's confident appearance and asked tentatively.

"Solution? I can give it a try...... However, I have to have Mr. Lao Nangong to give me a measuring stick and a rope. Shi Yuan smiled and put forward his own needs to Nangong Rong.

Nangong Rong couldn't help frowning when he heard Shi Yuan's words. These barrels are narrow at the bottom and wide at the top, different heights, different sizes, and bulky...... On weekdays, the standard small wooden barrels are used to add water, and now these pulp barrels have rainwater, and if you want to add some raw materials to it, unless you use small wooden barrels to measure it bucket by bucket, but this method is too cumbersome, and it is time-consuming, and the measurement error is too large, so he had to pour out the rough pulp...... However, when he saw Shi Yuan's confident smile, he couldn't help but be surprised, and secretly said in his heart: Does this kid really have a way?

Nangong Rong asked Shi Yuan to find a measuring stick and a rope, and he looked at it quietly on the side - he wanted to see what this kid could do!

Shi Yuan took the rope and measuring stick, and then asked people to take out the bamboo soaked in the pulp barrel, and he was busy measuring it on the tall pulp barrel - although these wooden barrels were of different sizes, they were all standard round table shapes! For the calculation method of the volume of the round platform, Shi Yuan remembers it very clearly! It is because of this that he has the confidence to say big things...... Thanks to the great math teacher!

Watching Shi Yuan go up and down, he used ropes and measuring sticks to compare those pulp buckets, and from time to time he used branches to write and draw on the ground, and the symbols he drew were very strange...... Lin Yingyue and the others watched quietly, but no one made a sound! After a while, Shi Yuan calculated the volume of several pulp barrels! The calculation is simple, but he spent a lot of effort on the measurement.

"Mr. Nangong, please borrow the utensils that measure water on weekdays!" Shi Yuan calculated the volume of the slurry barrel, turned to Nangong Rong and said.

Although Nangong Rong didn't understand what this kid was going to do, he still asked people to bring a small wooden barrel to measure. Shi Yuan took the small wooden barrel, measured the volume of the small wooden barrel with a measuring stick and rope, and then asked Nangong Rong again: "Dare to ask Mr. Nangong, how much water and how many ingredients are usually filled with slurry?" ”

"Twelve buckets of water, plus about five buckets of thick paddles!"

Shi Yuan heard this, so he counted on the ground again, and after a while, he got up and said to the craftsman of a paper mill on the side: "This pulp barrel adds half a barrel of ingredients, and this pulp barrel adds three-fifths...... It's sixty percent ......" He was commanding the worker while chattering in his mouth, while the people behind him had different expressions, Nangong Rong was a little puzzled and embarrassed; Lin Yingyue also had some doubts on her face, but she was a little surprised; And Li Maomao was just full of surprises......

"That's it! Mr. Nangong, can you see if the ingredients I added are still accurate? After adding the ingredients for the last pulp barrel, Shi Yuan turned around and said to Nangong Rong with a smile.

"Don't be in a hurry to rejoice! I'll try it later! Nangong Rong saw Shi Yuan with a smile on his face, snorted softly, and walked to the pulp bucket in confusion.

saw Nangong Rong walk to the pulp bucket, found a slender bamboo, stirred the water slurry a few times, and then took out a spoon and looked at it carefully...... Lin Yingyue and Li Maomao on the side saw Nangong Rong's movements, and their faces were full of nervousness and expectation. Nangong Rong first glanced at the water slurry in the spoon, slightly surprised, and then he dipped some water slurry with his hand and gently rubbed it a few times, his face was already full of puzzlement! Finally, he put the juice in his hand under his nose and sniffed it gently, then closed his eyes...... After a long time, he said slowly: "I lost ......."

"I knew it! Brother Shi Yuan can definitely do it! Hearing Nangong Rong's words, the little girl Li Maomao shouted happily; Lin Yingyue on the side had a slight surprise in addition to the incredulity on her face...... Li San, on the other hand, looked suspicious, and looked at Shi Yuan with a trace of resentment in his eyes.

"The old man is a good man, since you can come up with a way today, I should call you a teacher!" Nangong Rong was very upright, and when he turned around, he was about to bow and bow to Shi Yuan.

"Grandpa Nangong (Mr. Nangong) can't ......," Lin Yingyue and Li San on the side shouted together.

"Grandpa Nangong, Shi Yuan was just joking just now, you don't have to take it seriously......" Lin Yingyue opened her mouth to persuade while giving Shi Yuan a look.

"Yes, yes, yes! Mr. Nangong, he just hit it by mistake! I can't take it seriously! Li San on the side also spoke...... Nangong Rong is the old man of the paper mill, and he also learned from him, if Nangong Rong called that kid teacher, wouldn't he call him the ancestor? That's not going to work...... Li San calculated in his heart, and hurriedly opened his mouth to persuade.

"You don't have to argue, I still have to ask for advice about the mystery, this teacher should be called!" Nangong Rong waved his hand to stop Lin Yingyue and Li San's persuasion, and was about to bow to Shi Yuan again!

"That old man Nangong, you don't have to call me teacher, I also learned this method of calculation from others......" Shi Yuan hurriedly said comfortingly.

"Oh...... There are such strange people in the world, I don't know what the name of this strange person is? Shi Yuan's words really made Nangong Rong stunned, and he asked.

"That...... Have you ever heard of Zu Chongzhi? Shi Yuan asked with a smile.

Shi Yuan's words made everyone present stunned, but Shi Yuan smiled secretly...... The area of this round platform is related to pi, and he said that he was handed over to him by Zu Chongzhi, which is not nonsense.

"Zu Chongzhi...... Over the years, I have traveled from north to south and traveled to many places, but I have never heard of it. Nangong Rong shook his head and said.

"If there really isn't such a person...... Shi Yuan said secretly in his heart, and then said: "That...... Mr. Nangong, it's normal that you haven't heard of it, this Zu Chongzhi is a mathematician in my hometown, and he came up with this calculation method. ”

"...... 'mathematicians' in your hometown? I don't know Shi Gongzi...... Teacher, where is your hometown? And what kind of position is this mathematician? Nangong Rong asked persistently.

This old man is quite stubborn, and he really calls me teacher...... Isn't that bigger than Lin Yingyue's chick...... Two generations? Depend on! How do you feel how old you are? Shi Yuan's heart wrinkled, and he said, "My hometown...... My hometown is thousands of miles away, so far away from here, so far away...... Don't mention it! That, Mr. Nangong, you should still call me Shi Yuan, don't call me teacher. ”

"How's that going to work? I will also ask you for advice on how to measure...... This teacher should be screaming! ”

"Mr. Nangong, do you really want to learn this measurement method?"

"Exactly ......"

"That's good! As long as you don't call me teacher, I'll teach you! ”

For this stubborn Nangong old man, Shi Yuan still has some respect in his heart: after all, this old man is a real skilled craftsman, and he just takes the lead of the traverser, if he becomes the old man's teacher, he will feel a little guilty in his heart...... So, Shi Yuan once again resorted to this scoundrel's means.

"How? Mr. Nangong, do you agree? ”

Nangong Rong was a little embarrassed, if he called Teacher Shi Yuan, he wouldn't be able to learn the method of measurement, if he didn't call it, it would be contrary to what he said before......

"Grandpa Nangong, you just promise Shi Gongzi! He may give you the measure...... Good no good? Lin Yingyue on the side saw Nangong Rong's difficulty, so she opened her mouth to persuade her.

When Nangong Rong heard this, he shook his head slightly and said, "It's okay...... And so I promise you! However, I'm afraid that the old man will bear the name of unbelief! Hurry up and give me the method of measurement! ”

When Shi Yuan saw Nangong Rong agree, he smiled and said, "That's right!" How dare a boy be your old man's teacher...... As for this measurement, it is also very simple! ”
