――――――――――――――――――――――

That night, when he arrived at Liu Mu's house, Qin Qiong signaled the rest of the people to wait in the distance first, and only took Jingde, Old Wolf and Liu Zhengze to go.

Inside the fence wall, Erniang Liu Ruyu is making calculations.

It is an abacus, not an abacus used by the Tang people.

"Four down, five to one, eight to two, into one......" Liu Ruyu is very serious, she is calculating the cost and profit of making a piece of soap.

Seeing Qin Qiong arrive, he was about to get up to greet him, and then saw that there were other people, quickly put away the abacus, as well as the straw paper on the small wooden table and a charcoal pen made of willow wood from the fine charcoal ash of the willow tree.

Putting these into a wooden box, Liu Ruyu arranged for Siniang to call Liu Mu, and stepped forward: "It's Brother Abao here." ”

Bao!

Wei Chi Jingde wanted to know Qin Qiong's interesting stories here, and he thought that there would definitely be many interesting things before he came, but he almost burst out laughing when he heard this title.

However, Liu Zhengze, the young soldier in the army, looked as usual, standing behind the two without saying a word.

Liu Mu also came out of the house, clasping his hands into fists: "Brother Bao." ”

Qin Qiong introduced the two beside her: "This is my friend, a blacksmith. Everyone called him Ah Carbon. ”

"Brother Tan is good."

"You call him Xiaozheng!" Since Qin Qiong planned to hide his identity to the end, he used the way of Liu Mu to call people, and gave the young soldier behind him a name.

"Brother Xiaozheng." Yanagi bowed respectfully.

The one who returned the favor.

"This is a friend of the green forest, and he has a lot of strength. The people of the green forest are called old wolves. ”

"Brother Wolf is good." Willow gave the salute again.

Qin Qiong continued: "Your method of green fodder must be a good thing, my friend of the green forest still has some money, so I hired some more people, let's buy some sorghum When it comes to winter, there are always some rich people who are willing to buy green fodder for horses, and this money should be spent." ”

"That's great, it's so good to work." Liu Mu looked a little excited: "What's even better is that I tried to burn the ashes with only pine branches, even if I don't add spices, it has a clear fragrance, and I also tried several different oils." ”

Jingde couldn't help it, turned around and smiled, but pretended to say to the soldier: "You can write, you go and call everyone to come and set up a tent first, and then prepare to do things." ”

"Good!"

Liu Zhengze is very smart, he understands that these two people have not revealed their identities here, so they will not add respectful titles and so on in the barracks before.

Liu Mu approached Jingde: "Brother Tan, the first thing we need is a guillotine, which is used to cut materials." The main ingredient is sorghum stalks, and then the auxiliary materials, I choose alfalfa grass and wild bean grass......"

Grass and digging pits are rough work.

Guillotine is a delicate job, but for Yu Chi Jingde, a guy who has not moved to strike iron for many years, grabbing a sledgehammer makes him feel nostalgic.

The most difficult thing for green storage is to seal the kiln and starter culture.

Liu remembers consulting agricultural experts online about how to do it without cement and plastic sheeting.

Who thinks, there are really many ways.

He found a place in the wasteland full of rocks in Liu Mu's house, and dug a pit that was one person deep, one zhang long, and five feet wide. Then use bricks to simply lay a layer around the perimeter, then add wooden boards, and then seal another one with a painted linen cloth.

Liu Mu, staring at Jingde striking iron.

At this time, Liu Mu was engaged in an ideological struggle, and he wanted to tell Jingde that he had a way to directly produce 100 steel.

But Liu Mu hesitated for two days and dismissed the idea.

Being too radical is definitely not a good thing, this steelmaking method not only has a huge investment, but also has little certainty of success, and there is only countless theoretical knowledge.

In addition, he has no roots and no foundation, and if he does such a big thing, he may be killed.

Yanagi gave up.

In the past few days of preparation, the young soldier has been paying attention to Liu Ruyu, not because Liu Ruyu is beautiful, but because Liu Ruyu has been holding a strange wooden plate with many beads when everyone is working, there are crackling beads.

"General, have you noticed what that little lady is doing?" Liu Shenjun found Qin Qiong.

Qin Qiong also paid attention to it, but didn't care.

Being reminded by Liu Senjun, Qin Qiong asked rhetorically: "Is there anything wrong?" ”

"It's not that it's wrong, but I think she's calculating, and it's doing it quickly. Yesterday afternoon, I heard her give Mu Langjun a detailed account of the expenses of these days. ”

Qin Qiong was interested when she heard Liu Senjun say this.

Originally, I was only focusing on the green material, but I didn't expect to find something.

During the afternoon dinner, Qin Qiong came to Liu Mu and Liu Ruyu approaching: "What is Erniang's plate with wooden beads?" ”

"It's an abacus." Erniang did not avoid Qin Qiong.

"What is an abacus?" Qin Qiong asked.

Liu Mu said: "Second sister, it's better to report the small accounts these days." ”

"These days, a total of 17,600 yuan has been used, of which ...... is used for eating, and the cost of each kiln is ......" Erniang Liu Ruyu reported in great detail, detailed to the cost of each kiln, each person's labor, the cost of eating, and the budget of the future cost of each kiln Tibetan green material.

"Second sister, you are right, but we will build the kiln, and we will only repair it every year, and the cost per catty of green material will not be so high next year. Of course, we will also have to calculate the cost of buying sorghum stalks in the future, which is also the cost. Yanagi brought up his thoughts.

"What Da Lang said is that I will record the others. It's just that this is twenty-three big dollars per stone green material, will it be too expensive. Now the price of grain is only two hundred and sixty cents per stone of millet. ”

Liu Mu smiled: "Didn't you say it, next year will not be the cost of digging a kiln." According to the ten years of use in a kiln, one stone of green material does not count the price of purchasing sorghum stalks, that is, five big dollars. ”

When the Tang Dynasty was at its peak, a big money was almost two catties of polished rice.

It is not yet in the prosperous age, and a big money can buy almost half a catty of polished rice, so Erniang is worried that the cost is too high.

But in Qin Qiong's eyes, there is no longer a high or low price, in order to make their BMW grow better, the cost is huge, and a purebred sweat and blood BMW from the Western Regions is not expensive.

At this time, Qin Qiong was shocked that this sister, who was only half an hour older than Liu Mu, was simply against the sky with her calculation ability.

This Liu family is a monster.

There is not only a willow wood, but also such a powerful Erniang.

Noticing Qin Qiong's stunned eyes, Liu Mu reported a fierce news at the most opportune time: "Brother Bao, my eldest sister is making medicine with Bai Zhenren in the Taoist Temple, I have half a month at most, and there will be a main medicine specially concocted for you, I believe that in less than a year, Brother Bao, your problem of loss of qi and blood will be much better, and I will think of better medicine." ”
