Early the next morning.

Qin Huaidao ate something and was about to go back to Qinjiazhuang, there were Cheng Chumo and Wei Chi Baolin in the Supervision Mansion, there was no need to worry at all, seeing He'er coming out, he was crying, he wanted to stop talking, and suddenly reacted before promising to take He'er to Qinjiazhuang.

The conditions in Qinjiazhuang are difficult, and a girl has had many inconveniences in the past, but it is not interesting to stay alone in the backyard, so her heart softened and she agreed: "Pack some change of clothes and go." ”

"Hey, Young Master Xie!" He'er was overjoyed, turned around and ran to the backyard, happy like a bird.

Not long after, He'er came out with a bag on his back, Qin Huaidao led the horse out of the house, and the two left.

After leaving the city, Qin Huaidao asked He'er to sit in front and gallop on his horse.

The two came to the ancestral hall of Qinjiazhuang, Qin Huaidao turned over and dismounted, hugged He'er, and said to a girl who was cooking: "Help me notify a month and make a bed out." ”

The other party glanced at He'er, and will come over with Qin Huaidao on a horse, the relationship must be close, and he hurriedly agreed, and hurriedly ran to find Mingyue.

"Follow me." Qin Huaidao said and led He'er into the ancestral hall.

In the ancestral hall, Jia Youcai was settling accounts, and when he saw Qin Huaidao coming over, he quickly got up to say hello, Qin Huaidao returned the salute and said: "Uncle Jia, in the future, this account will be handed over to He'er, and the accounts in the house are also taken care of by her, don't miss it, you free up time to manage everyone's production and quality control, this is more important." ”

"It's great that He'er came to help, the old man can't wait to see these accounts every day, for fear of making mistakes." Jia Youcai said in surprise.

"You two will hand it over, but Uncle Jia is still responsible for the distribution of the silver, and He'er is only responsible for keeping accounts, and He'er can't keep it all busy." Qin Huaidao admonished, went out of the ancestral hall, asked someone to inquire, and found Huang Lao who was supervising the work on a hillside.

"The young master is here?" Huang Lao greeted him.

"Old Huang, ask something, where are there more stones?" Qin Huaidao replied and asked, the affairs of the court should be put aside for a while, just use this time to burn lime, if you can study the cement, it would be better.

"Stones?" Huang Lao thought for a while and said: "There is a hillside about three miles to the west, which occupies a small area, and there are a lot of stones on it, but they are relatively large and not easy to move, what does the young master mean?" ”

"Find someone familiar with the road and take me to see it."

"The old man can still walk." Huang Lao did not accept the old man and led the way in front.

Qin Huaidao followed, chatting about the production progress of the village while walking, and unconsciously came to a hillside, the hillside is less than ten meters above sea level, it is a gentle slope, covering an area of not small, there must be more than ten acres, there are many stones on it, overgrown with weeds, you can't see tall trees, a few birds are frolicking.

The stones on the hillside could not be used, Qin Huaidao came to a collapsed place, and saw that the stones in the soil were white, the particles were crystalline and strong, and they looked like coarse salt ore, which was dolomite, and he was happy in his heart, and went up to break off a piece to take a look, and smiled after making sure that it was correct.

On the hillside, Qin Huaidao walked and observed, and soon found a fracture surface, which was gray-white limestone, which was also the material for burning lime, and looked up, not far away was a river, and there were many stones on the river beach, of different sizes and shapes, all of which were suitable building materials.

After observing a circle, Qin Huaidao found that the entire hillside was full of stones, the soil layer was less than half a meter deep, and there was only a thin layer in many places, no wonder no big trees had grown, and asked, "Huang Lao, whose mountain is it?" ”

"No one wants the place where you can't grow grain, and I don't know if there is a master, so you have to ask the county government."

"Let's go, let's go back." Qin Huaidao was sure in his heart, with these stones to burn lime, he would not worry about the materials, but it was far away, and it was a bit troublesome to transport.

The two returned to Qinjiazhuang, Qin Huaidao found Jia Youcai to explain the situation, and advised: "Go to Chang'an County Yajiang Mountain immediately, it doesn't matter how much money it is, if there is a master, you have to find out who it is." ”

"Young master, what are you doing with the stone mountain, and you can't grow grain." Jia Youcai asked curiously.

"It's useful, just do it."

Jia Youcai saw that Qin Huaidao's tone was resolute, so he didn't say a word more, and hurried away with the silver.

Qin Huaidao returned to the ancestral hall and saw that He'er was accounting for the accounts, and said with a smile: "Is there a problem?" ”

"It's not a problem, it's just too much, and it takes some time to get used to it."

Qin Huaidao took the account book and saw that the numbers were all capitalized numbers, and all kinds of income and expenditure were mixed together, and he had a headache when he looked at it, so he said: "Teach you a simple bookkeeping method." ”

Saying that, Qin Huaidao picked up a piece of charcoal in the bonfire and wrote Arabic numerals 0 to 9 on the ground, while teaching He'er, He'er has a strong memory, and he wrote them all down after listening to them twice, and asked with some curiosity: "Young master, what kind of symbol is this, I have never seen it, and it looks quite magical." ”

"The numbers from the Western Regions are the most convenient for bookkeeping." Qin Huaidao explained, asked for a few blank pieces of paper, and drew three tables on them with charcoal, marking the income table, expenditure table, and summary table respectively, and wrote some small words in each table.

After the drawing was completed, Qin Huaidao explained: "Look at this income table first, all the income every month is recorded in this table, which day, because of what, how much income, how much unit price, how much, who gave the silver, are clearly recorded, and there is a place for the payer to sign and draw the pledge, and it is very convenient to check the number of accounts in the future." ”

"It's really, the young master is so powerful!" He'er said in surprise.

"And the same is true for this expenditure, the date, the reason, the unit price, the quantity, the summary of the daily expenditure, etc., must be available, and whoever receives the amount of money must also sign and draw a pledge, so as not to make mistakes, omissions or not admit it in the future." Qin Huaidao said and picked up another summary table.

"This one looks different." He'er said curiously.

"Yes, this is only four contents, including last month's balance, this month's expenses, this month's income, this month's balance, each of which includes silver, items and other things that need to be counted, so that each month's expenses and balances are clear, will not be messy, until the end of the year to summarize, then teach you how to do accounts, is there anything unclear?"

He'er didn't dare to be sloppy, and asked the doubts in her heart one by one.

Qin Huaidao carefully explained the reasoning, and it didn't take long for He'er to basically write it down, but he said with some worry: "He'er basically wrote it down, but I've never done it, and I don't know if I can do it well." ”

"It's okay, it's okay to make mistakes, and if you don't understand, feel free to find me."

"Young Master Xie taught such a wonderful method of bookkeeping, He'er will do it with his heart."

"You figure it out for yourself first, and I'll go around the area." Qin Huaidao admonished, walked out of the ancestral hall, came to a hillside, and saw that the palace guard was burning coal and making coke, there were a lot of piles next to it, and the brick kilns were also smoking.

One person came over, and after making a gesture, he said: "Young master, the mud tube has been installed in the kiln and has not been burned yet." ”

"Let's go, let's see." Qin Huaidao said.

The two soon came to a kiln, Qin Huaidao looked at the mud tube inside, it was scattered, the gap was kept well, this thing had not been burned himself, there was no bottom in his heart, thinking about the temperature of the bricks burning more than 1,000 degrees, this thing may be below 1,000 degrees, try it first, and then adjust it.

After pondering for a moment, Qin Huaidao advised: "You are responsible for this kiln, the temperature should not be too high, you can burn it directly with coal, put an iron block at the mouth of the furnace to test the temperature, the iron block can be reddish, once it is red, it will cool down immediately, and it will not hurt to burn it, try boldly." ”

When the other party heard that it was okay to burn it, he was relieved and asked, "Young master, how many days will it take to burn?" ”

Qin Huaidao didn't know how many days to burn, fortunately, it was not a work of art, the requirements were not high, just use it, thinking that it would take three or four days for others to burn clay pots and tea sets, and he couldn't be too little, so he said: "Burn it for three days and three nights first." ”

The other party quickly wrote it down and took action.

Qin Huaidao observed for a while, and saw that the other party's movements were quite proficient, so he put his mind at ease, as for the result, if it can't be redone, try more, and it will eventually succeed.

After waiting for a while, the fire came up, and Qin Huaidao saw that there was no big problem, so he asked Huang Lao to transfer people to dig two smaller kilns, ready to try to burn lime and cement.

As long as you try more, you won't believe that you can't burn out.
