Ma Yan's porter has stepped down, and the original porter rushed back before the Spring Festival, saying that he had brought his parents and wife to live in Gong'an County.

"Fortunately, with the blessing of Liu Jingzhou, a fat boy was born in the cheap."

The original porter's face was dark, but his face was overjoyed when he said this.

Although it sounds strange to Ma Tan, it is very good to be able to share a good red egg.

After eating the red eggs in a small bite, he just saw Mr. Kong Ming smiling at him when he raised his eyes.

Ma Yan's face flushed, and it was really ungraceful to eat while walking.

Kong Ming smiled and beckoned over to assign Ma Jian a new job.

"Chopping wood?" Ma Tan was confused with three points of grievance.

"It's not just chopping wood." Kong Ming patiently explained: "Give you ten strong men to accompany you, cut down the grass and trees around Gong'an County, cut down thirty catties of each type according to the category, and transport it to the county government, which is of great use to me." ”

What's the big deal about that? The county government wants to stew pork for a banquet for the township fathers?

Ma Yan, who was full of doubts, took the order and left.

Behind the public security county government, Sun Qian called the craftsman again.

Because Kong Ming has now officially moved his office to the side hall, other public houses will not be used for the time being, Liu Bei waved his hand: Now that we know the formula, we will also make paper!

After Kong Ming calculated the cost and selling price of Zuo Bo paper for Liu Bei in detail, no one present was unimpressed.

A roll of Zuo Bo parchment paper is almost equivalent to a piece of silk and is worth 1,200 yuan.

But the cost is only in the process of making hemp paper, which costs 180 yuan, and the raw material of mulberry is added.

The price has skyrocketed more than tenfold, which is really ......

"I, Lao Zhang, if you want to have this means, what kind of butcher will you do!" This is Zhang Fei's exclamation.

Thinking of General Zhang's words, Sun Qian couldn't help but smile:

After ten years of running around with the lord, with the Jingzhou foundation, Sun Qian felt like he was in a dream, and now it is the grace of the light curtain from the sky, which made Sun Qian firm up the idea that he had already identified:

The lord is really a hero of the Han!

"What is this doing?"

Sun Qian turned around and saluted, "Mr. Liu just came back?" ”

"This year, the lord has taken Jingzhou, so he wants to catch up with this Spring Festival celebration." Liu Yan smiled and said: "Gongyou, we are ten years old acquaintances, just call me Weishuo as many times as you like." ”

Seeing that the craftsman was leveling the ground in the backyard, and there were hammers placed next to those low houses, and he didn't know what to build again, Liu Yan was very curious:

"But the lord wants to rebuild this place as a place of governance?"

"Definitely." Sun Qian shook his head and said, "The lord sees that there is a lot of open space here, and he plans to make paper here." ”

"Papermaking?" Liu Yan raised his head and thought: "What is it used for?" ”

"Sell for money."

If you don't understand, you don't want to, Liu Yan turned his mind and asked, "What about the lord?" The good wine of the Zhang family in Jiangdong was brought back by me for a few jars, and the lord will definitely like it! ”

"The lord went to find the divine doctor Zhang Zhongjing." Sun Qian said honestly.

"Zhang Zhongjing?" Liu Yan was stunned: "Divine doctor? ”

"Divine Doctor!" Sun Qian nodded, very sure.

Liu Yan touched the back of his head, I only left Gong'an County for three months, how can it be as if three years have passed?

At night, Zhuge family, after dinner, let the servant take the three children to play as usual, Kong Ming and Huang Yueying said some thoughtful words around the stove.

"The lord and I have talked about it, and in a few days the county will set up a craftsmanship department, which is still in my charge, and I want to recruit you as a craftsman and craftsman officer."

Kong Ming smiled: "Don't you feel sorry for that Zuobo paper is too expensive, let's make this Zuobo paper in the first step." ”

"Where did the lord buy the secret recipe?" Huang Yueying said curiously.

"It's a long story." Kong Ming thought about it and took the bamboo tube that he never left his body, extracted the last few volumes of the light curtain copied inside, and explained the ins and outs to Huang Yueying in detail one by one.

Yesterday, before the lord left, he still had a private discussion with Kong Ming, in view of the importance of science and technology and craftsmen in later generations, he first set up a craftsman department in Gong'an County, and the first thing was to restore the printing technology mentioned in Zuo Bo paper and light curtain.

The Ministry of Medical Engineering is also in preparation, and it is said that everything is ready, Zhang Zhongjing, and the death of Shu Han's heavy ministers mentioned by the light curtain has cast a layer of haze on Liu Bei's heart.

Huang Yueying's eyes were full of color when she heard the strange things, but when she heard Kong Ming's self-description that she might eventually die on the march due to overwork, at the age of fifty-four, she secretly wept again.

"The husband is like this, how can the concubine live alone?"

Kong Ming let out a long sigh and hugged Yueying into his arms: "We will not be like this. ”

In this way, Wen Yan comforted Huang Yueying for a while, and temporarily revealed the matter, and soon understood:

"The curved plough and round cart of the last month are also ......"

"That's right."

"I see!" Huang Yueying suddenly realized, and a smile bloomed on her face again:

"But husband, it's better not to set up the Ministry of Craftsmanship in the county government, I'll show you something."

Saying that, Huang Yueying got up and pulled Kong Ming all the way through the hall to a small room in the backyard.

Lighting the copper lamp lightly, Kong Ming saw the scene in front of him: on the table was a round cart the size of a palm, which was placed in a groove cut out of a log, and the round cart was connected to the same small stone grinding mortar and other things through the crank and the like.

Before Kong Ming could figure it out, Huang Yueying lifted the half bucket of water next to her and carefully poured the water into the log trench.

The water drives the round car to rotate in a circle, the round car drives the wooden handle, and the wooden handle drives the stone mill and the mortar.

Kong Ming is no stranger to the art of craftsmanship, and after looking around twice, he understands the advantages:

"Don't need any human drive?"

"More than that......" Kong Ming muttered, "If the round car is enlarged by five times, the grinding disc and the mortar will also be expanded to five times the size, and only three seats will be needed to meet the needs of the entire Gong'an County, and we can charge per time, even if we only charge seventy percent of the market price...... No, no, no, only 50% will be charged, and all the heads of the public security counties can come here to process grain! ”

"No, no, what if you only charge 10% or 20% or even nothing?" Kong Ming anxiously circled around the room, and he could feel as if a door had revealed a crack in his mind, and that gap revealed an enchanting golden light.

Huang Yueying could understand her husband's anxiety, so she thought together:

"If only one or two percent is charged, wouldn't the pressure on widows in the county be greatly reduced?"

"Widowhood can easily make ends meet...... Kong Ming thought along the way: "The amount of work is greatly reduced. ”

"If there were something like a round cart in the field, it could be cultivated with water power......

"You don't have to work all year round." Huang Yueying also seemed to understand: "With enough food and clothing, knowing etiquette, the world of great governance is just around the corner." ”

But soon Huang Yueying poured a basin of cold water: "If you want to spread all over Kyushu like this, how much wood do you need?" How many craftsmen are needed? ”

"And the water power is endless, and the strain at the joints of the round car is very fast, as the husband said, it expands by five times...... No, not five times, even three times, the wooden parts at the joints may only last half a day. ”

"These require a lot of money, and round cars can only be used in places where the water is fast, how many places in Kyushu can meet these requirements?"
