Infrastructure maniacs from the East

Xu Tian made a ruler.

It's not as tall as you think, and it's not complicated to make. He asked a carpenter to make a smooth and flat board, then cut off the head and tail, and drew about the length of his own arm, and declared that it was a piece of wood. Ruler, in order to make this ruler that is useless in the eyes of others, and to speed up the production of farm tools, Xu Tian specially asked the housekeeper to "hire" a carpenter from the city. Frightening and taking his family with him is not what Xu Tian cares about.

After many attempts, he found that he could not divide it into ten equal parts. Xu Tian directly divided it into sixteen equal parts by dividing it into two parts, two parts into four parts, and declared that one foot equals sixteen inches, The word "inch" is a modern Chinese character for flowers, and the pronunciation is also standard Mandarin, and it is shamelessly called Tianchi.

Yes, it was Xu Tian's day.

Xu Tian is really fed up with vague words about what the world should be like. He should have thought of this when he was making plows before, otherwise the parts he made would not always be wrong. It’s not too late to come out. He solemnly handed over the initial scale to the butler, and asked the butler to go to a blacksmith to make the exact same length. He was really afraid that one day the wooden ruler would disappear due to some shit. Compared with iron, it is more precious, and the housekeeper will pay more attention to it.

How to divide the length into two Xu Tian also thought about it for a long time. After all, he had left school for many years. Then he saw a branch with forks. In an instant, his blood rushed to the top of his head and his IQ exploded. He doesn't know how to divide a foot into ten parts, but he knows that one foot is divided into two.

The branches looked like slingshots. Xu Tian had someone pick them up and processed them to serve as temporary compasses—the bark was peeled off, the trunk was smoothed to prevent the lord from hurting his hands, and the slightly longer one was ground out at the bottom. The thin ones are like the tip of a needle, and the shorter ones are all smoothed and put into the fire to roast the front. They are not taken out until they are carbonized, and then they are scalded with boiling water before they are dared to be put on the pottery plate for the lord.

Xu Tian doesn't know how much this branch has gone through, but he doesn't need to know, after all, he is a superior who only needs to wait for success, not those hard-working executors. What he cares most about now is this branch Can you make compasses? If not... Then find another branch. Anyway, the land here is sparsely populated, and there are forests everywhere.

Fortunately, it works.

Xu Tian breathed a sigh of relief, and so did the servants.

Put the sharpened part against the edge of the board, Xu Tian used the tip of another carbonized branch to draw a black arc on the board, and then pressed it against the other side to make it according to the law. Fortunately, the branch was long enough, and the two black lines Xu Tian connected two points on the top and bottom of the wooden board with blackened hemp thread, and the place where the first line intersected was the midpoint.

It's just that Xu Tian doesn't care whether it's elementary school, junior high school or high school. He's just glad that he still remembers these useful things in his head, otherwise just a weight and measure would exhaust people to death.

After the initial ruler is done, the next thing will be done soon. Use carbon to draw a small mark on the sixteenth equal parts, and then explain the meaning of the ruler and inch to the housekeeper, and then ask the housekeeper to find someone to make a few identical ones. Come on, this one made by Xu Tian himself will be imitated by the iron ruler, and then it will be carefully collected by the housekeeper together with the most similar one.

One foot and ten feet, one foot and sixteen inches, this size that gradually became the standard was developed on this ordinary day, because it was developed by the lord of Fibrina's territory, and most everyone used it It was called Febrina Lord Ruler, and later people thought the name was too long, so they just called it Lord Lord Ruler. Tianchi, who was named by Xu Tian himself, was not known to many people.

During the time when wooden rulers were produced in large quantities, the housekeeper gave simple training to the servants, mainly to learn the ten Arabic numerals and the corresponding simplified characters, the progressive relationship between tens of millions, and the respective meanings and meanings of the rulers. In order to write, I also specially made wooden boards and rough charcoal pencils, and wrote three Chinese characters for everyone to remember.

The result... According to the lord's order, the housekeeper didn't force them to learn, so most of the progress was the same. After all, there were only a few who were serious, and some people didn't study at all. Whispering, I brought more people who didn't want to learn anymore, and the housekeeper didn't care about them. After finishing the courses they were supposed to take, they went to work on the things the lord ordered, until the wooden rulers were produced in batches.

No one noticed that there was a thin figure at the doorway that was temporarily used as a classroom.

Carpenter and blacksmith are compulsory for the city lord to learn. Xu Tian really doesn't want to see those parts of different sizes. In the case of possible losses, they will always become extra cautious, so even if carpenters and blacksmiths complain a lot in private, they have learned it seriously.

The learning process is very hard, but after understanding these, their parts error rate dropped rapidly. Xu Tian was very satisfied with this, and the carpenters and blacksmiths did not have any complaints. After all, they can use these data in the future, especially It's a carpenter. After all, if the blacksmith makes a wrong size, it can be remade, but if the carpenter makes a mistake, the wood will be discarded. These are all shiny coins.

A large number of rulers have finally been produced. Naturally, only the lord can use the precious iron rulers. Everyone else uses wooden rulers. The scales on them are just a thin black line, but it will not disappear when you wipe it with your hands, because These are actually the appearance of a carpenter who cut a slit with a knife, then sprinkled it with crushed carbon and wiped it clean, so that a ruler will not be useless in an instant because of accidentally erasing the scale.

The butler summoned the servants again, and took out a roll of parchment with a strong smell and two clay pots.

It is said to be a basin, but the height around it is only about five centimeters, but it has a bottom of about half a meter, with a layer of mud inside, and a wooden stick with a rested bottom is placed beside it.

The other has pure water in it.

"Today there is an exam."

At this time, Emily was arguing with the stone mason. Since she was uttered by the stone mason to give up, her father-daughter relationship with the stone mason had unilaterally dropped to a freezing point. There was a fight every two days, and she But her mother would only cry and blame Emily, and forcibly asked Emily to apologize to the mason.

The mother's tears made Emily temporarily surrender again and again, but her heart became colder and colder, and she hated the family more and more, and the way of getting along with the stonemason became "hate the stonemason-argument-mother crying ——Apologize—the vicious circle that I hate the mason even more, and run out whenever I have time.

The castle treated them much better than they could have imagined—thick paste for every meal, separate rooms, and 'clay bowls', which sounded odd, but really It sounds very nice, and the pottery bowl is also very useful, but unfortunately they can only get one at home.

The most important thing is that they can help with the work here, and then they can eat delicious 'brown jade'. The pronunciation of these two words is also very strange, but Emily learned it quickly, after all, it can be correct Those who say these two words can get an extra spoonful of brown jade, which is as big as a fingernail. However, after Emily saw that the brown jade she brought back to her mother was eaten by the stonemason for granted , she never brought it back.

"You don't do anything and don't bring things back, what do you look like doing nothing all day!"

The stonemason's voice was not loud, because last time his roar alarmed the servants, the housekeeper came over and told him to leave directly next time, he didn't want to lose such a big business because of such a trivial matter.

"I can't eat what I brought back."

Emily lowered her head, and her voice was not loud, but she stepped on the stonemason's explosion point accurately. He jumped high, his face was flushed, and he looked at his daughter as if he saw something dirty.

"Either you come back with something in the future, or you don't come back."

This was the last sentence Mason and Emily said. He was very confident that Emily would be soft. After all, Emily was just a girl, and there was no possibility of living without her father and brother. If it wasn't for the place where he lived was the lord He will seal up the room, so that this shameless daughter will not run around.

"Emily..."

The mother's weak voice came, and the prematurely old face was full of tears.

"it is good."

Emily's complexion was very strange. She slowly raised her head and met the mason's eyes. The mason subconsciously turned his head away, as if trying to avoid something.She looked at her mother again—worried, anxious, and even slightly blamed...without a trace of anger towards the mason.

She moved her lips, uttered a single syllable, then bit her lips tightly, clasped her palm tightly with one hand, pushed open the door that symbolized the rupture of the relationship between father and daughter, stepped out, walked away, no longer look back.

The content of the test is actually very simple. The Arabic numerals and simplified characters from one to ten are written silently, plus the writing and pronunciation of the simplified characters of Zhang, and finally there are questions such as how many inches is one foot, and how many feet is equal to one foot, but it is as simple as that However, only three people could type out the question smoothly, and the rest could only half-answer part of it correctly, or simply asked three questions, which made the butler who was mentally prepared even angry.

"Come up."

The three people who passed the exam came up in a little confusion. The butler asked them to wash their hands in the clay basin filled with water, then stood in a row, took out three rulers and solemnly handed them to them, and the three of them took it in a little confusion. , subconsciously clenched.

"You've done a great job, so you're going to have a new job."

The butler dropped a bomb as soon as he opened his mouth, and the crowd of servants immediately buzzed. Many people looked at them with mocking eyes—servants were considered the best job in the territory.

"How much did you have before, but now you can get as much as two copies."

The second bomb was dropped, and all the eyes with negative emotions immediately turned into envy and jealousy. Regret began to spread, but there is no medicine for regret in the world.

"My lord, I can."

He ordered three people to come and look for him later, but the housekeeper was stopped by a person on the road, and the housekeeper hadn't reacted when the voice came to his ears.

"I can do those topics."

Emily looked into the butler's eyes, and her trembling voice became a little louder, hoping that the butler would give her a chance.
