Chapter 47 Infrastructure

Shi Kuan hesitated: "Fourth brother, this kid ...... Is it Godless? Brought out of the womb? ”

Shi Fu said: "I don't know this, I only know that he is good at anticipating things, observing subtleties, especially actuarithmetic." Give him a magnet to play with, and he will find the iron layer under the sand by the river; Give him a copy of "Nine Chapters", and he will be able to deduce the technique of opening the square, and use it to cut the circle, brothers, do you know how shocked I was at the time?! ”

After speaking, he pointed to the exquisite folding knife: "Such a beautiful utensil, what is it in Su You's eyes?" It's just a plaything he gave to Vier, just a trail. ”

Shi Kuan looked at the folding knife and handed it to Shi Fu: "You tell us about the mechanism." ”

Shi Fu said: "I can't tell, but Su You drew the drawings, look at his fine drawings, you can know that Su You's technique is not just as simple as the design of the mechanism, he is passing on a knowledge to us, and it depends on whether we can understand it." ”

After speaking, he ordered the disciple to take the drawings, open the drawings, and put a vernier caliper: "This drawing, with this magic ruler that can be refined to one-third of a centimeter, according to Su You, can be called engineering." ”

"This science is based on arithmetic. If you master it, you can create all kinds of utensils, from huge anchors to hundred-foot tall buildings, to clothes hooks and arrows, and jade locks and gold rings. Exquisite, exquisite. ”

Shi Shou picked up the copper ruler: "How can this be so fine?" Wait, this scale is so thin, it's carved with a needle? How can such a thin needle withstand force without breaking? ”

Shi Fu said with a smile: "Three brothers, let go of prejudice, and after the younger brother explains to everyone one by one, you can know the ingenuity of Su You's thoughts." ”

Waiting for Shi Fu to explain the working principle of the vernier caliper, then talked about the forging principle of patterned steel, and then talked about the smelting and etching technology of brass, and finally said: "This kid's theory seems to be mysterious, to put it bluntly, it is actually a fine." For example, pattern steel, before we were at most folding and refining, where did we want to get so many tricks from him? To put it bluntly, this is actually the craft of making noodle dolls. ”

"Another example is the centimeter ruler, the caliper has been there since before the Han Dynasty, but there is more than the principle of complementing the difference in the nine chapters, and the accuracy is immediately increased by ten times, the reason is so simple, it is not difficult to understand. But we can't even think of it. ”

"There is also brass, we all know the truth of bronze, brass is actually the same, but the lead is consumable, and it becomes white lead when it encounters fire, and it is difficult to fuse. Why didn't you think of putting a lid on him to keep out the air? This...... This is the truth of braised mutton! ”

At this time, the attitudes of Shi Fu and the other three were completely reversed, and Shi Kuan said: "That's so, but if you can think of exercising feathers through noodle dolls, you can think of smelting brass from braised mutton, and you can deduce the difference relationship through addition and subtraction and apply it, this kid is really ......."

Shi Shou said: "Big brother, why don't you go and tell Su Bagong on the other side that the matter of Su You will be forgotten, and the two families will rebuild the old relationship." ”

Shi Wan said: "Heavenly Master's decree, these five feather-patterned swords have to fall on Su You's body, or ...... Over there in the iron mill, give him a stake again? ”

Shi Kuan thought for a moment and asked, "Fourth brother, what do you think?" ”

Shi Fu raised his nose and raised his eyes: "He is so beautiful!" Ruined my family's reputation for Vier! You'll have to take him accountable for this! ”

Shi Kuan was very depressed: "Fourth brother, the Su family can't be offended now......"

Shi Fu Zhenzhen said: "What happened, can Wei'er still marry well?" This thing was made by Su You! He's going to have to marry Vale! Now that the two of them are still young, let's set the doll kiss first, and wait for Wei'er to become an adult, and the sedan chair will carry it! Big brother, let me tell you, now you have to put on a posture that it is their fault to ask the teacher for the guilt, Su Bagong is a sincere person, he, just eat this! ”

Shi Kuan suddenly realized, and said with a smile: "Reasonable!" Now it seems that fortunately, there is the previous one...... My Shi family has picked up a treasure this time. ”

……

Not to mention that the four brothers of the Shi family were there to calculate the details, Su You was shopping with the fifth group of children at this time.

Ten dollars, as long as you don't buy clothes, it's enough to buy something else.

The first thing I went to was the grain store, black beans, mung beans, sesame seeds, peanuts, rice...... That's nearly 100 catties, 20 catties of soybean oil, and 5 catties of tea oil.

Then there are two more stones, then a fine sieve, a dustpan, a basket, a mat, and a vegetable mound...... All kinds of rough make it home.

In the end, twenty sets of gold mining wooden dustpans were customized in the carpenter's workshop, and it took less than five times in total.

Valuable, that is, iron, axes, kitchen knives, knives, planers, saws...... Shi Tong originally came to give his master a set, but Su You refused.

But this thing is really expensive, and there is no way but to pay on credit.

Then I bought paper from the Cheng family and pottery from the Shi family, but these were all given at market price, and there was no credit.

Cheng Wenying and Shi Dongxiu watched with a smile as the children moved things, and Su You was fooling around.

Coal is cheap now, and pulverized coal is even cheaper, and Suyou also needs a big car, only 500 yuan.

I also bought a small stone mill and two pairs of wooden barrels, both of which are now expensive, more than three in total.

Back at the Land Temple, Su You called the children to one place, turned out the book, read it to them one by one, and then said: "A total of seven guan four hundred and thirty-five wen money was spent, and there are two guan five hundred and sixty-five wen left, which is a total of ten guan, and in addition to the purchase of iron tools, I also owe Shi Jia 25 wen to the iron shop!" That's the ledger here, I've lent it to you, and you'll have to pay it back to me in the future. ”

The second child was older, more than ten years old, and he was frightened when he heard this number: "Little master, we can't afford to pay so much money......"

Su You said: "If you can't afford it, then earn it!" From today onwards, follow me to earn money! ”

The fourth said: "Little master, it's not that I don't earn, in the past, the eldest brother took us, and the income was only enough for the younger brothers and sisters to eat and drink, and even the clothes had to be worn in rotation, this, how can this be repaid......"

Su You put the notebook on the table, flipped out another notebook, and said, "Don't worry, I'll count everyone's names and ages first." Dick starts with you. ”

The second child said: "My surname is Li, my family tells me to be tethered, you can write twelve when you are young!" ”

Someone below immediately stopped doing it: "Tie up the liar!" You'll grow up a little bit, and you're only eleven when you're old! ”

The second brother raised his eyebrows: "What are you arguing about?!" I'm the dick! The second child is a little bigger than the old one, just twelve! ”

A group of children shamed him, making Su You a head and two big, knocking on the table and quickly stopped: "Don't make trouble!" Tie up your brother, don't make a false report, just tell the truth, I will assign work to everyone according to my physical strength. ”

Finally honest, and when the statistics are down, many children have been abandoned for a few years, not to mention that their names are nicknames, and they don't even know their surnames.

Su You frowned: "Otherwise, your eldest brother is everyone's benefactor, and if you don't know what your surname is, how about your surname Zhang?" ”

Xiao Dirty said: "Don't do it! Am I not called dirty? ”

Su You said with a smile: "Xiao Dirty is not dirty now, ugly names can no longer be used, if you want to report for official registration in the future, just call Xiao Mei." ”

Little dirty or not dry: "That's still a dirty little girl!" ”

Su You was so entangled that he couldn't help it: "You have to get it, do you have my surname?" The surname is Su, Su Xiaomei! Wait, that's a proper noun......"

The little dirty had already run away: "Oh! From now on, I will be called Su Xiaomei! None of you are allowed to call me dirty again......"

Uh, okay, anyway, that Su Xiaomei in history was originally a fabrication, so use it!

Today's main thing is a retreat, just like the opening ceremony of the head teacher to see a new classmate, inform the name, set up a few class rules, talk about hygiene, assign cleaning or something, and then arrange for the girls to take the paper paste windows, and the boys continue to mud.

For the rest of the small ones, let them take baskets to collect firewood and grass, and they themselves took a few big ones to cut bamboo in the bamboo forest.

After walking a long way, he saw some big bamboos, Su You selected a few old ones, taught the boys to cut them, and then shaved off the bamboo branches with a kitchen knife, tied them into a large bundle, tied them to the bamboo with bamboo strips, pushed them into the water, and put them until they were put into the inlet of the stream into the river, and then dragged onto the beach.

Seeing a clump of dry reeds at the water's edge, Su You also asked the children to collect them and bring them back to the Land Temple together.

Placing the bamboo under the eaves, Su You circled the bamboo pole with fine hemp rope, took out a pencil, drew a part of the same diameter and thickness, and asked a few older children to saw some bamboo tubes with a diameter of three inches and a height of three inches.

Then use sand to polish the inner surface smooth, take the clay, roll it into a clay tablet, and take a bamboo tube to cover some round clay pieces.

Draw on the clay piece with a compass, mark the idea, and use a bamboo stick with the thickness of the index finger to poke out a round hole of uniform distribution and consistent size.

Dry this piece of clay and use it as a mold to make the same hole in other small clay tablets.

Two large round clay tablets were also made, with holes in them, one with many holes and one with only five.

Finally, let the boy press the clay board and cut it into thick rectangular strips.
