Of course, Han Qian didn't hand over everything here to Zhao Ting'er, and when Fan Xicheng took people into the mountains to quarry, he took off his robe, found a straight board, buckled out a groove, and injected water to use as a simple level.

In this way, he can ensure that the iron grate of the upper mouth of the stove does not tilt, otherwise uneven force is most likely to cause collapse.

There are no ready-made iron slivers, so thick iron bars are made on site, crisscrossed and embedded in the furnace mouth of the burnt stone stove for support, as long as the holes are small enough to prevent charcoal and limestone blocks from leaking out.

In addition to ventilation and fire control, these can also allow people to observe the smoldering lime.

When the lime is fired into a stove, as long as the lime is discharged from the iron grate to the lower stove, the large stove can be used repeatedly, unlike the stone stove made by the soil method, which needs to be picked up to transport the lime.

Of course, it is also convenient to pile up the earthen burning stone stove.

By the end of the day, the new stove had been built.

Feng Yi and Kong Xirong dislike these are cheap jobs and don't know how to do it, but they also enjoy standing by and watching, and make fun of Zhao Ting'er from time to time.

Just after nightfall, Fan Xicheng also brought people back with more than 20 baskets of limestone in bamboo baskets.

When he saw the wall of the stove of Qi height, his eyes were unusually straight, and he had nothing to say; Before they returned, Han Qian also asked people to dry the stove wall with firewood for later use.

Firewood is mainly made of wheat straw, which is readily available, but the bottom layer of the stone stove needs to be covered with a layer of charcoal for support. Fortunately, there are also charcoal kilns nearby that specialize in burning charcoal and transporting it to the city to sell, just send someone to buy it directly, and a car of charcoal is more than 1,000 catties, and it doesn't cost 30 yuan.

That night, according to the new method, the firewood and limestone were spread into the large stove layer by layer, and then the stove was sealed and smoldered.

After eating at night, Han Qian was still not very relieved, and took Feng Yi and Kong Xirong to run down to watch the production of the lime kiln, and the five kiln burners did not dare to slack off, and they were still in front of the kiln.

As long as the stove is built steadily, whether the lime can be burned or not, in fact, as long as you pay attention to the heat.

And at this time, you can see from the stove that after the calcination of the lowest layer of limestone, there is already a little powder that has been burned to iron gray from the top of the iron grate, take out some mixed water, and look at the beep, it is indeed lime.

"The big stove may need to be burned for two more days, but this method can be done without a doubt, you will build three more big stoves tomorrow, and the Qingbai stone must also ensure that it can be supplied." Han Qian instructed Fan Xicheng.

After Fan Xicheng came back, he also asked Guo Nuer in detail about the method of measuring the straightness with a wire hammer and a wooden trough with water, and said that it was not complicated at all, but when he heard that Han Qian wanted to build four large stoves at the same time to burn lime, he said in embarrassment: "To carry a sufficient amount of Qingbai stone out of the mountain, I am afraid that there are not enough people in Zhuangzi!" ”

"How is it not enough?" Han Qian asked strangely.

The four preliminarily renovated stoves can burn an average of 20 loads of lime per day.

At this time, it is the farming season, and the tenant farmers are resting and are willing to help the villa to change the family's three full meals.

In addition to the manpower who helped build the big stove and ash storage warehouse in the workshop, in addition to following Fan Dahei, Lin Haizheng and other family soldiers to obey Shen Yang's dispatch and help settle the people who were infected and hungry, Fan Xicheng currently has twelve or thirteen strong laborers to bring into the back of the mountain.

In Han Qian's opinion, there are enough manpower at present.

Fan Xicheng was bitter and explained the reason to Han Qian.

They went into the mountains to quarry, and the means were quite crude, mainly looking for those weathered and crisp limestones, which were easy to knock down with a hammer, and then used people to carry bamboo baskets down the mountain.

When the people of the world can endure hardships and stand hard work, they can go deep into the mountains, and they can carry two or three hundred catties of limestone down the mountain a day.

More than ten people enter the mountain, and they can carry three or four thousand catties of limestone every day, but Han Qian has to build four big stoves in Xiwandi, and he has to carry seven or eight thousand catties of limestone every day, which is more than double.

Not to mention that twenty or thirty loads of lime are produced every day, which is far from enough for the military government.

"If you go up to the grange, isn't there a blue and white stone, why do you want to run so far?" Han Qian asked strangely.

"The stone layer at the head of the ravine is too hard, and with the strength of milk, I can't drop a few pieces of gravel after hitting it with a hammer for a long time; With the iron drill, you can't knock it a few times, the iron drill will be scrapped, and you have to go into the mountains to find cracked blue and white stones, which is more troublesome. "It's not that Fan Xicheng hasn't considered quarrying nearby, but he has discussed with the quarryman and the stone burner, if it weren't for the fact that the blue and white stone here is too hard, how could they be willing to go far?

"Alas!"

Han Qian's previous thoughts were all spent on making up for the wasted time and gaining his father's trust, and at this time, he really set out to do some things, and only then did he know how simple the craftsmanship of the world was.

Han Qian didn't know what the level of the master craftsmen under the jurisdiction of the Shaofu and for the royal department was, but the level of these skilled craftsmen in the people was really not enough.

Seeing that the night was dark at this time, Han Qian instructed Fan Xicheng to say, "Tomorrow morning, you ask everyone to prepare a bundle of firewood and a wooden bucket for water, and wait for me at the head of the ditch - you really have to teach everything by hand." ”

Fan Xicheng looked ashamed.

"Quarrying, you too?" Feng Yi asked curiously.

"Bet on another Hepu bead?" Han Qian asked.

"......" Feng Yi shook his head.

Since he gambled on black and white in the Linjiang Hou Mansion, he and Han Qian didn't seem to have won anything.

Losing a gold coin, he can still not feel distressed, a dragon's eye size Hepu bead is worth hundreds of thousands of dollars, he usually takes one or two with him to play, but he doesn't dare to bet with Han Qian like this.

…………

…………

Early the next morning, Han Qian slept until dawn, then got up lazily, practiced Shi Gongquan and then ran to the back mountain with Feng Yi and Kong Xirong, accompanied by Zhao Wuji, Zhao Kuo and other family soldiers.

Fan Xicheng had been waiting for more than ten strong laborers to wait there.

The snow melted, the mountain road was muddy, Han Qian slipped in the mud halfway, and Feng Yi laughed for a long time, and at this time he didn't say much when he went to the head of the ditch, and asked people to clean up the weeds and dead trees around him, so as not to spread the fire, clear out a quarry, cover the firewood on the limestone and ignite it, and pour cold water on the firewood.

Listening to the cracking sound, a large piece of blue and white stone surface cracked out with many lines......

"What's the solution?" Feng Yi was dumbfounded,

"You idiots who don't learn and don't know how to learn, none of you can think of such a simple solution?"

There is no ready-made mountain road, one foot deep and one foot shallow, Han Qian just went up the mountain and fell a dog eating, was ridiculed by Feng Yi for a long time, and was nesting a belly of fire, at this time his temper is naturally good, and he is not polite to Fan Xicheng and Zhao Kuo, and asked,

"How many broken things will there be in the future, and I will teach you how to save trouble and effort? Use your brain to do anything! ”

Fan Xicheng and Zhao Kuo were scolded with a look of shame, thinking that they would be able to quarry nearby in the future, even if they still used bamboo baskets to carry them, and opened up a small path along the ravine, one person ran more than a dozen back and forth a day, more than a dozen strong laborers, and it was not a problem to carry thirty or forty thousand catties of green and white stone every day.

At this time, there was a noise of trampling of people and horses below, Han Qian didn't know what was going on, and after a while, he saw his father Han Daoxun and Shen Yang, accompanied by Zhang Qian, Guo Liang, Han Laoshan, Lin Haizheng, Fan Dahei and others, walking through the woods and walking this way.

"Father, how did you get to the villa early in the morning?" Han Qian asked.

"Today's rest, I'm fine at home, so I took Han Laoshan out of the city to breathe,"

Even if the epidemic water is written by Han Daoxun, he is extremely eager to get relief for the infected and hungry people, but he is not willing to intervene in the battle for succession, and naturally he is unwilling to admit that he came over to see the preparations here, and said,

"I just met Lord Shen, Lord Yang, and General Guo before I arrived at the villa, and I heard that you brought someone to quarry here, so I came over to have a look."

Listening to his father, Han Qian knew that there was a middle-aged man in his forties behind Shen Yang and Guo Liang who was wearing cyan civilian clothes, and he didn't know which great god he was, so he mixed up with Shen Yang and Guo Liang in the morning, but he just stepped forward and saluted: "Han Qian has seen Lord Yang." ”

"It is said that Han Jia Qilang does not learn and has no skills, but I didn't expect Han Jia Qilang to also know this method of fire and water agitation!" The middle-aged man in the green robe said with appreciation when he saw that the surface of a large piece of blue and white stone in front of him had cracked open and become easy to pick.

Nima, does anyone have to say that he can't learn if he doesn't learn?

Han Qian scolded secretly in his stomach, but he still had to pretend to be well-behaved and said: "Emperor Liu Bang of the Han Dynasty practiced the strategy of repairing the plank road and secretly crossing the Chen Cang, although the soldiers did not go to the Shu Road, but the thousand-mile plank road of the Baoxiao Valley still sent people to repair, and the method of digging a stone cave is to burn the water and fire, Han Qian happened to have heard his father teach. ”

"Hmmm! The Han family's family learning is really not simple! The middle-aged man nodded at Han Daoxun and praised, "In a word, I know that your son-in-law knows history, knows military strategies, and knows how to apply it. ”

Han Qian looked at Feng Yi and Kong Xirong curiously, and wanted to ask them who this grandson was, and he looked like he was high when he talked to his father, but seeing that he was wearing a cyan regular uniform, his official rank should not be high.

"The girl below who commanded the craftsmen to build a big stove, the method of measuring straightness she learned was also taught by you?" The middle-aged man continued to ask Han Qian with great interest, "Your father and Lord Shen are both well-read, and they don't know how to build a big stone stove like this, what kind of book have you read?" ”

"Knowing the ancient law but not knowing the progress is a big disadvantage of the craftsman." Han Qian said impatiently.

"Bastard, do you know who you are talking about such a big thing?" Han Daoxun taught Han Qian and said.

The middle-aged man didn't mind, and bowed his hand to Han Qian very politely, and introduced himself: "Yang En, the right school officer of the Major Mansion, has met Han Gongzi. ”

"Ah, Lord Yang, Han Qian lost his words." Han Qian was startled, and hurriedly lowered his waist and saluted.

The right school of the Shaofu is in charge of plate building and other work, and the right school is the material officer, to put it bluntly, he is the big leader of the royal craftsmen.

Although the right school director can be said to be the master of craftsmanship in the world, in the era when craftsmanship is a cheap industry, the status will definitely not be too noble.

Real power or not real power is another matter, at least it is far less than Han Daoxun's secretary and young eunuch Qinggui at this time.

However, when the right school officer was appointed by a very special person, this person was Yang En, the brother of Emperor Tianyou.
