Fall in love with the technology tree [Three Kingdoms]

Asheng played with the pencil in his hand. From the outside, it was no different from the pencils of later generations: hexagonal wooden strips, with a thin cylindrical stone grinding body inlaid in the middle.Sharpen it with a blade, and you can draw thick black handwriting on the paper.

She originally thought that she would use wicker to burn charcoal to make hard pens, but she never thought that the history of Chinese people using graphite is much earlier than the history of using pine smoke ink.It's just that hard pens have never been able to become the mainstream of writing, and graphite and water grinding are nothing but inferior inks.

Carpenter Ai stood in front of her desk with hands down, her weather-stained face seemed to still carry the chill of the autumn wind outdoors.

"It's too soft." A Sheng said, in a calm tone without much emotion, and he doesn't need encouragement to communicate with a technical nerd like Jiang Ai. "Look, I just wrote ten words, and I need to sharpen the pen again. How long can such a pen be used? How much time does it take to sharpen the pen during use? And—" She reached out and wiped the white paper The graphite powder on the paper was smudged, and the handwriting was blurred immediately. "look!"

Graphite pens have various disadvantages, otherwise they would not be in a weak position and be crushed by soft pens.The graphite pens made by Jiang Ai are already top-grade compared with the contemporary products. At least he knows to cook the wood to make it easier to be cut by a knife, and the graphite is also compacted.

Carpenter Ai was expressionless, but his eyes flickered twice. "Xiao Langjun has a deep heart, so don't play it."

"Mixed pottery clay. It doesn't have to be high-grade pottery clay, you can try ordinary clay. Different ratios of clay and graphite can make different hardness, corresponding to different purposes. Add water to mix and compact into the mold and then calcined at high temperature , the texture will be tighter."

The man's expression brightened in an instant, and he became energetic: "Besides clay, do you need to try other things? Such as spices, iron powder, and charcoal powder." The soul of the experiment was burning.

"Don't... just. I told you, the method of controlling variables can't be chewed off."

"Oh." Suddenly lost.

"And you have to remember one principle." Ah Sheng threw the pencil on the table, "For this kind of consumables, the simpler the craftsmanship, the better, and the cheaper the materials, the better. I want to give it to the children of the Yuyingtang and the servants of other courtyards. It’s for reading. Add iron and spices to it? Huh? Do you want to mix it with gold?”

Her sarcasm made Jiang Ai's face tense.A big man who has been in the workshop for 20 years is ridiculed by a doll, and even a little bit of self-esteem can't help it.But what she said is right, Jiang Ai's skills are good, but she often goes astray on some directional issues.

"Besides, don't use the riveting method to inlay wood. The small graphite pen casing is also worthy of your skills? Find a better adhesive, semi-mechanized production will be used sooner or later."

Adhesive and mechanization are not the first time Jiang Ai has heard these two words.In fact, the paper-pressing skills of the metal roller set provided by Ah Sheng had already made him full of admiration for the concept of "mechanization". This is why he signed a death contract with Cao Sheng after saving enough money for redemption.

He prides himself on being a genius who has dabbled in all kinds of crafts and knows everything.But since he came under the name of the young man of the Cao family, he has been refreshing his knowledge of his profession every day.She is not a professional craftsman, but what she knows and thinks has a kind of oppressive forward-looking from the top.

No matter how arrogant he is on the surface, he is clear in his heart: follow this person, maybe he can go down in history like Cai Lun and Lu Ban.

"Winter is coming, if there is anything missing at home, just tell me. Although there is a lot of work, don't stay up late, the body is the heaviest." Asheng gave the craftsmen very generous living treatment, especially for craftsman Ai. The same standard as a manager like Zeng Shi.

"There's nothing missing here."

"The servants at home, I let them take turns to help in the workshop. If there is someone you like, feel free to ask me for someone."

"Oh! They are all mediocre!"

Ah Sheng chuckled, "That's fine." In the future, she would let the orphans who had received elementary education go, and there would always be someone who could satisfy Carpenter Ai.

After the muscular man stepped back, Ah Sheng couldn't hold back his smile anymore.

"Master is happy?" Luo Chi asked, "He pretended to be serious in front of him."

Ah Sheng picked up the pencil and looked at it over and over again. The technical progress was still in the second place. The appearance alone made her feel kind. "In fact, he mixed other ingredients into it, not clay, but wood powder or glue. Pure graphite is much more brittle than this. And this one is already close to 12B."

Luo Chi couldn't understand the word "12B", so he smiled and pretended to be cute.You can often hear new words around Xiao Langjun. It doesn't matter if you don't understand them once, and you will understand them after hearing them a lot.

Ah Sheng is in high spirits today. "Does any of you know how to draw?" She asked as she rummaged through the sample paper made in the workshop, and picked out the thickest cardboard with rough fibers.

This topic is beyond the outline.How can a person who has been sold as a slave since childhood be able to draw?At this time, painting requires at least pen, ink and paper, which the people at the bottom cannot afford.

A Sheng was poured with cold water, and sullenly threw the pencil and cardboard to Yan Wen who was serving behind him. "Forget it, just pretend I didn't ask. Help me get my coat, and I have to go back home to study today. Where's brother? Another early morning to harm Zhao Weng's Yuncai?"

Yun Cai, or Hu Cai, is a seed sent from the northwest by my grandfather's friend.At first, Ah Sheng thought it was something rare, but when he saw it, well, it was rapeseed!With rapeseed, there is no need to squeeze beans. Next year, there will be vegetable oil to eat. Just think about it.

Now the autumn wind has risen.Most of the fields in the farm are interplanted with soybeans and winter wheat.The same relatively cold-resistant rapeseed was planted beside the ridge of the experimental field.Ah Sheng is not an expert in agriculture, but she knows that soybeans have a nitrogen-fixing effect, and interplanting staple foods is conducive to high yields; and rape is one of the more common vegetables in winter.

"What harm are you talking about?" Little brother Ji Li perfectly interpreted what is meant by "Say Cao Cao, Cao Cao will arrive". He strode in from the outside and threw a pear to Asheng, "Eat it quickly, I know you like this."

Well, instead of harming rapeseed, it is harming fruit trees.

Before the coachman from Feitinghou's mansion arrived, Ah Sheng ate the overripe pears in twos and then took his companions and his brother back to the city by car.

At this time, the carriage was a symbol of status. There were clear regulations on the number of horses pulling the carriage, the umbrella cover used for the carriage, and the material of the decoration.As for the Cao family, which started as an eunuch, it would be too ostentatious for a child to ride in a carriage. Therefore, Ah Sheng and his elder brother rode in an ox cart.The bullock carts are spacious and can be modified and installed with walls at will, but they walk slowly.

It was already around ten o'clock in the morning when we returned to Feitinghou Mansion.

Cao Teng checked the twins' homework last time, and taught them some common etiquette knowledge, and it was lunch time.

"Ruyi's arithmetic is simply known from birth." Grandpa sighed, "You have someone write out the other court's account books on paper, which is better than Shaofu's. It should be handed over to the imperial court for promotion. However..."

"However, the account books are written too clearly, which is not conducive to some people's harm to the public and private interests." It was not Cao Sheng who Cao Teng expected, but Cao Cao who answered this question.

"Auspiciousness is getting better and better the more he learns in the other courtyard."

"I heard from Zhao Weng that most of the officials are... well, the geese are overwhelmed, and the poor are all civilians in the end." The little brother is still too young, but he has an upright spirit in his nature. "Eunuchs, relatives, the most greedy!"

Cao Teng's expression became stiff.

Ah Sheng quickly said: "Brother is wrong, the family is the most greedy. Who is born rich? The truly honest officials are often not passed on to the family. To starve to death is to become a slave, and even learning is delayed, and there will be fewer talents gradually. But all those who are rich now are lying on the people's fat accumulated by their ancestors. Brother, don't look at the children of the aristocratic family who claim to be more noble, that is Their ancestors have accumulated wealth, land and fame, and they don’t need to worry about these anymore in their generation.”

The primitive accumulation of capital is permeated with blood and sweat.But Cao Teng and Cao Song are still on the stage of primitive accumulation.Ah Sheng has been shopping for treasures in the warehouse all year round, and from the changes in the items in it, it can be inferred that Cao Song is not clean, and Cao Teng probably acquiesced.The Cao family's background is too weak, the land must be accumulated, the servants must be cultivated, and the relationship must be exchanged, so they cannot afford to be honest.As long as it is not something harmful to nature, the gray income will be taken if it is taken. After all, the Eastern Han Dynasty is no better than the later generations.

If this was the dynasty in its heyday, Ah Sheng might still feel guilty about poaching the corners of the country.But at the moment, the Eastern Han Dynasty is slipping towards collapse. Ideologically corrupt Confucianism is on the rise, politically messed up by eunuchs and relatives, the lower-level promotion channels are monopolized by aristocratic families, and ordinary people die in groups due to natural and man-made disasters, but they can’t wait. Court rescue.This dilapidated house needs to be repaired rather than demolished and rebuilt.Moreover, her brother is Cao Cao!

Cao Teng smashed the table, pulling Ah Sheng's Piaoyuan thoughts back. "Enough! You...you two...you can't say this outside!"

Grandpa got angry, and the twins quickly and tacitly lay down on the ground. "We made a mistake. We dare not say it outside. We only talk to our grandfather."

Cao Teng was still panting heavily. "I'm only four years old after the new year, so I can't worry about it, how can I be okay when I grow up?! Geely is too upright, Ruyi... the eyes are too vicious."

Ah Sheng blinked innocently. Although what she said was a bit extreme, there must be some truth to it. "I understand, I understand. Brother, we are a vested interest group."

Cao Cao bowed his head in thought, thinking about the phrase "vested interest groups".

Cao Teng gave up and threw the bamboo slips away: "Eat!"
