Wang Xuan gave himself two days off, and stayed in the coal mine for the thirteenth and fourteenth.

At present, the use of coal is only the most primitive combustion, and even then it is only a small part of the development.

In Wang Xuan's view, the new city is a complex of buildings, and it is impossible to install a stove upstairs for drinking water and eating, so he wants to get the briquette stove out.

Wang Xuan's family used a briquette stove in winter before, and he has used it for decades, so he is no stranger to it. The briquettes are simple to make, just mix the coal slag with the appropriate proportion of loess or clay, and mold it.

Generally, the briquette ventilation hole is 12 holes, and the hearth can be filled with three briquettes, and a family of four is basically enough for a meal.

The number of workers in the coal mining area has almost doubled from last year, nearly 1,000 people are working, and the mining area has expanded considerably, leaving behind small lakes.

The slag was collected by the workers and piled up in the open space next to the warehouse, like a hill.

Wang Xuan was more curious, so he asked Zhu Dali why he still collected and stored these slags.

Wang Xuan was very moved by Zhu Dali's answer, he said that slag and coal are the same, but they become fine particles and are not easy to sell. With the wisdom of the Lord, there may be a way to use the slag, and it may be possible to turn waste into treasure, so collect and store it first, and even if you throw it away in the end, you will not lose anything.

After Wang Xuan praised Zhu Dali, he began the trial production of briquettes.

First of all, arrange for the guards to get a hammer, break the slag, try to make the pieces smaller, and make up enough catties.

Then ask the guards to notify the hardware factory to create the furnace shell: the stove top, the furnace shell, and the bottom of the furnace.

The stove surface is the platform that supports the heated utensils such as pots and basins, and it needs to be concave and convex so that the fire below can come up through the gap with the air.

The furnace shell is a cylindrical shell wrapped in iron sheets, which plays a reinforcing role, like the outer wall of a steel-making blast furnace.

The bottom of the furnace is the support chassis of the furnace, which is basically a triangular support.

Wang Xuan also marked some details on the diagram, including the installation of load-bearing handles on the furnace shell, the installation of ventilation control valves at the bottom, and the installation of iron bars carrying briquettes inside.

Then he sent someone to the lake in the north to take the loess, add water and mix it thoroughly according to the ratio of one coal and four coal, and stir it evenly.

Wang Xuan made a simple ball-making mold with a bamboo tube, and inserted twelve bamboo branches in the middle to act as ventilation holes, leaving small holes at the bottom to exhaust. The mixture of coal and loess is packed into a bamboo mold and compacted so that excess water and air are discharged from the small holes at the bottom. Then turn it upside down and push the bottom baffle, and the whole briquette is pushed out, and after drying, it is ready to use.

Nearly 300 briquettes were made in the morning, stacked in rows, and let Dali send people to keep an eye on them, and then moved them into the warehouse for storage after drying.

In the afternoon, Wang Xuan sent someone to fetch clay, and he wanted to burn the refractory furnace base.

The refractory bricks used for this furnace are much better than loess, which can make more efficient use of heat energy and are more durable.

First, make a mold with large and small bamboo tubes, stir the clay evenly, control the water, and remove bubbles, and then load the clay into the gap between the two bamboo tubes, evenly stack and squeeze. After molding, remove the outer and inner walls of the mold, and dry them before they can be installed and used.

Worried that the furnace made would not match the plan, Rixuan also went to the hardware factory the next day and described some details and requirements in person.

On the evening of the 14th, Wang Xuan returned to Jixiang City and had dinner with Hua'er, his favorite gnocchi soup.

"It's been a long time since I've eaten noodles!" Wang Xuan muttered.

"What are noodles?" Hua'er's ears were very pointy, and she suddenly looked at Wang Xuan with a curious face, and her eyes were full of warnings: Don't try to fool me!

"Well, noodles are strips of food made of noodles...... Wang Xuan pondered for a long time, and finally gave up.

Wang Hua's expression made Wang Xuan clearly realize that if he didn't make a meal for this little ancestor, it was estimated that the future would not be clean. Women have always been very vindictive, regardless of size.

So he said to Hua'er a little flatteringly: "Brother will make you noodles tomorrow morning, okay?"

"Then I'll call the eldest sister and the second sister to eat together. "Hua'er is still a little worried, so she simply pulls the two of them on their backs.

Wang Xuan is speechless, no matter what new food he makes, this girl has to bring the two sisters here. No way, it's impossible to make dough, and the simplest way to make dough has to have alkali to neutralize the sourness, but unfortunately baking soda hasn't been found yet. Then you can only make dead noodles, but fortunately, there is no big difference for noodles.

Early the next morning, Wang Xuan came to the kitchen to get flour and noodles. After reconciliation, start rolling dough with a bamboo tube, and it must be rolled to a thickness of less than two millimeters to be qualified. When I was a child, this task was usually done by my father, and it was gradually replaced by dried noodles, but handmade noodles have always been Wang Xuan's favorite noodle dishes, for no special reason, just because they contain familiar flavors and strong nostalgia.

To make noodles for four adults, it is generally a one-square-meter tabletop with the skin after rolling, so that there can be four large bowls after it is done.

After rolling out the dough, Wang Xuan rolled up the dough with a bamboo tube, then removed the bamboo tube and cut it with a knife.

The noodles cut with each knife are as thin as wicker, sprinkle a little flour and shake them with your hands to prevent them from sticking.

The guards had already lit the fire, and Wang Xuan put the unknown animal oil into the pot, put in the wild onion and wild garlic and stir-fry until fragrant, and then add water. After about a quarter of an hour of boiling water, add the noodles and beat in four wild eggs.

When the water is boiled for the second time, add the greens, an appropriate amount of water, and stir appropriately.

After boiling the water three times, turn off the heat, add salt, and remove the noodles from the pan.

At this time, the three sisters were already seated at the dinner table, and when they saw the guard come up with hot noodles, Hua'er stood on the stool and looked into the bowl regardless of her image. The hard-boiled eggs in the ceramic bowl are on the top, followed by a circle of greens, a layer of oil flowers on the side of the bowl, dotted with stars, and noodles like spring and snow below.

Seeing this, Wang Xuan pretended to scold, and Hua'er felt that it was a loss, so she didn't bother with Wang Xuan, and sat down obediently.

The noodles were served, Wang Xuan also sat down, picked up the chopsticks and devoured them, I haven't had such a grand meal for a long time!

The familiar feeling came as expected, and although the taste was a little light, the charm in the bones was as fascinating as ever.

At this time, Hua'er didn't wait for everyone's reaction as if she had eaten dumplings before, and picked up chopsticks and hurriedly ate them.

After a while, after hearing the sound of Suosuo, three big and one small, ate the meals of four adults, and the soup was not left, which was really comfortable.

Hua'er touched her round belly and shouted to go to sleep, but was picked up by Wang Xuan, and honestly followed the eldest sister and second sister for a walk.

Aunt Liu was also very surprised, the two young ladies who are usually dignified and virtuous have a very heroic breakfast today, the so-called food is silent, but this sucking sound is really not small, so her eyes stared at Wang Xuan.

Your expression betrays your heart, even if you do it on purpose.

So Wang Xuan told Aunt Liu about the noodle method, and the name was green vegetable egg noodles!

On the morning of the 15th, after giving classes to the children, Wang Xuan "sat on duty" in the Government Affairs Yuan, and the approved list was a money-spent application, and he was upset! In the afternoon, he went directly to the hardware factory, and the stove shell should be ready!

After inspecting the size and quality, Wang Xuan nodded with satisfaction and asked the guards to pay the final payment.

How dare Niu Jing accept Wang Xuan's money, don't live or die, no matter how Wang Xuan coerces, people are Wang Ba who eats scales and has an iron heart.

To say that people in high positions are very accurate in principle, Niu Jing's posture Wang Xuan is not easy to criticize, so he had to place an order for a thousand sets of furnace shells again, and Niu Jing's eyes couldn't see it, so he took the cost price half-pushed.

Then Wang Xuan and his entourage went directly to the coal mine to load briquettes and make a fire for trial.

The firewood ignited the briquettes, the ventilation valve at the bottom was fully opened, and the first briquette was ignited and then the second and third briquettes were added.

A quarter of an hour later, Wang Xuan asked Zhu Dali to fetch a clay pot for making tea, fill it with water, and then put it on the stove and boiled it.

In the case of the ventilation valve is ajar, the water is boiled in less than a cup of tea, which makes the 'coal boss' Zhu Dali amazed, a strong Taoist is the master, there is always a whimsical idea, the magical ability to turn waste into treasure, no one can match!

This half-baked praise made Wang Xuan laugh, which was very useful. Sure enough, it's a thousand clothes, and the sycophants don't wear it!

Although Zhu Dali's sycophants reached a new height and a new realm, Wang Xuan did not leave him a stove.

In the afternoon, the guards came to Wang Bi's residence with a burning stove, accompanied by nearly 300 briquettes and makeshift tongs!

After Wang Xuan demonstrated the use of the stove to Wang Bi, Wang Bi couldn't put it down. There are so many benefits to this, the amount of smoke is small, the footprint is small, it can be used at any time, it can be moved at any time, and it can be extinguished at any time......

"This is used to match the buildings of the new city?" Wang Bi also understood Wang Xuan's intention of such a design through various judgments.

"It's not all, but this one is much better than the stove, and the cost doesn't increase much, which should be a good thing for everyone. Wang Xuan also said honestly, "This is also my dowry to the eldest sister, there should be a special person in the management of the design and material supply, and then I will send him to the eldest sister, or let the eldest sister come to learn, as you like!"

Wang Bi didn't know what to say at this time, she understood the truth that it was better to teach people to fish than to teach them to fish, what Wang Xuan is doing now is to teach her to fish, and in the end she just said with concern: "Brother Xuan should pay attention to your body, you are still young, the days are still long, you still have to carry such a big stall as Jixiang, you must not be overworked! Liu Liu, this person must have been investigated, we don't have any special talents to help you, but no matter what, we must be standing by your side in the end." ”

Wang Xuan was also convinced of this, and the family did not speak two words, and left after chatting.

Wang Yue was still looking at the stove in a daze, and when Wang Bi saw this, she teased: "Envy, then find a good family, let the eldest brother give you a better dowry, and we will still be neighbors at that time!"

"Sister, what do you say about Brother Xuan's brain, why did he come up with such an idea, so surprising and reasonable, could it be that a serious illness can really change a person?" Wang Yue was also a little dazed at this time, Wang Xuan's recent series of performances exceeded her cognition.

"Shut up!" Wang Bi scolded Wang Yue loudly, there are more filthiness within the aristocracy, which one has ever been clean? No matter how Wang Xuan has become or their cousin, this is an indelible fact. Now this cousin lord thinks about them everywhere, and what else could he want. Besides, how can there be a reason for being a sister to doubt her younger brother, and if your own family is still like this, how can outsiders stop?

Wang Yue also knew that she was speechless and was silent!

"Well, it's not surprising that Brother Xuan's personality has changed dramatically, as for how these new ideas came about, we don't have to explore the end, it's rare to be confused!"

This is a very serious statement, which is equivalent to a direct warning.
