The next morning.

Shibei Hutong, Zhao Duke’s Mansion.

In Jingyi Hall.

The old Duke Jiang Duo was wrapped in a big bear's skin mattress, revealing a small head outside. At first glance, it looked like a potato.

But no one from the state dared to underestimate this old man...

Jiang Duo raised his hairless brow, curled his shriveled lips, and looked at Changsun Jiang Tai and said, "The emperor said that the three major camps of Shenji should be handed over to the hands of absolutely loyal and reliable people. Because the little bastard of the Jia family was about to blow the firearms into the sky... The Forget Bacai, he knew that he was buzzing in front of the emperor. However, the firearms camp was indeed an important place. The emperor said that there were not many people who could trust him, and the Jiang family ranked first. So, I wanted to hand over the Zhulong camp to the children of the Jiang family and cited your name. What do you say? Hey, just listen carefully and say it carefully, don't raise your face. The balls are so long, I'm dizzy when I look at it!"

Jiang Tai: “…”

He pondered for a moment and said, "Old ancestor, I don't understand the firearm camp very much, my grandson still wants to go back to the navy..."

Before he finished speaking, his father Jiang Bao scolded him: "Damn beast! Have you praised you as a face? Don't urinate, do you want to see if you are worthy of being whispered here! Dog fuck..."

Before I finished scolding, Jiang Duo's little head suddenly stretched out and spat hard in the direction of Jiang Bao, cursing: "The dog is fucking the vulgar seed! I haven't finished speaking, you fuck your mother's mouth? I see Brother Tai is ten times better than you. Everyone in the Jiang family thinks it is the king of heaven. There is nothing he can't do. The stubborn guys of the wild buffalo have the face to scold others? Why don't you pee and see your virtues!"

Seeing that Jiang Duo suddenly became breathless, Jiang Bao knelt down and said, "It is easy for a father to beat him or scold him. Can you ask someone to beat him or scold him? You are so angry that your son has become a very unfilial person?"

Although he had prayed countless times in his heart that the immortals died soon, he was not stupid after all. He knew that the reason why Emperor Long'an met this respect to the Jiang family was because of Jiang Duo's supreme prestige in the army. The Tian family needed this prestige? Adjust the military structure and gather military power.

The Jiang family should take this opportunity to get more benefits? It is not too late to die after the benefits are obtained.

Is something going on now? Then the Jiang family is going to have a big problem...

Jiang Duo may understand this thought, or he may not care, he snorted, saying, "Brother Tai has indeed grown up? He understands his position and knows what he can do and what he can't do. But the more this happens, I feel more at ease to let you go. Be a general of the camp and find out the tactics of the firearm camp. I vaguely heard that Western firearms are different from before. Now, the firearms in the firearms camp, can they open a fire? Can archery shoot five or six wheels? It's hard. On rainy and snowy days, when windy days, it's not as good as a fire stick. But now there is a new firearm? Not afraid of rainy and snowy days and strong winds..."

Jiang Bao couldn't help but say, "Master? My son has also heard of the self-propelled firearm. It's extremely expensive. A firearm is almost worth hundreds of taels of silver, which is extremely labor-intensive. With the addition of the medicine, how can it be assembled in large quantities?"

Jiang Duo wanted to scold him, but he was old at the end and just said "he...she" and continued to say to Jiang Tai: "After you go, take charge of the troops and watch and learn. If the firearm camp is really as magical as the Jia family's Forget-Bao Cave said, your position in the future is crucial, have you remembered it?"

Jiang Tai nodded, and suddenly saw Jiang Lin standing beside him, with a gloomy face, hesitated for a moment, and said, "Old ancestor, why don't you... let Brother Lin go?"

Jiang Duo cursed: "Just just after praising you, you are confused! This is the emperor's golden words and words that he appointed you as a general, and it is also what you used to give in to him? Xiao Linzi, your elder brother is afraid that you will be jealous and hateful, and disaster will arise. What do you say about the dirty seeds?"

Jiang Lin knelt with a wry smile: "Old ancestor, I feel a little uncomfortable, but that's my elder brother, where is it?"

When Jiang Duo heard this, he rarely smiled and said, "I know that my seeds are not that stupid! Okay, I'll get up. By the way, I heard from Brother Lin's daughter-in-law that there is a kind of thing called heating in the Lin family, which is very warm. It seems that they are not burning with braziers, but hot water and hot air... I'm talking nonsense. The little balls of the Jia family are sucked, and they don't do serious things. They are all tiny all day long, but they are also sucking and making fun of gold. Tsk, it would be great if I had my seeds. Go and ask if I can also prepare a set of them. Although the red charcoal given in the palace is good, I still feel a little dry."

When Jiang Lin heard this, his face became entangled, but he didn't dare to say anything...

...

Ningguo Mansion, in five rows on the west side of the horse shed.

Li Xuan looked at the warm house and rows of vegetables, his eyes straightened...

I even ignored the smell of livestock feces that almost made him nauseated when I first came in...

"Good balls! How much money did Taiguan Garden spend in the Interior Ministry? The vegetables made were just wilted. His mother's group of Wangba used silver frost and charcoal to cook the kang, but they couldn't cook good vegetables. They were either leeks or soybean sprouts all day long. Eating a cucumber was like sleeping with his daughter!"

As he said that, Li Xuan picked a green cucumber from a cucumber rack, wiped it with a handkerchief, took a bite, and his mouth was filled with fragrance!

"I've sent it!"

"Jia Qiang, you have too many ways to make money, but you have to come together. Isn't there still a mountain of gold in the West Mountain that hasn't been done? Why did you make another mountain of green gold?"

"I think this transaction is more prominent and more expensive than rushing coal!"

Jia Qiang shook his head and said, "Who ordinary people can afford this? Even noble people... most of the houses have cellars and stored them. Except for a few that are really expensive, not many people can afford this."

The cellar is a good thing, even ordinary people can store cabbage or something. Of course, they eat more pickled vegetables.

In winter, try to warm a plate of garlic sprouts on the head of the fired kang and release a pot of bean sprouts, even if you try it out for the New Year.

However, there is a cellar dedicated to the family of high-ranking officials and nobles, called Caidongzi.

A few extremely noble families even grow vegetables on the kang.

And the cost of doing so is extremely high.

In contrast, Jia Qiang's greenhouse looks expensive, but it is not.

The greenhouse uses glass as windows and the heating room uses fertile soil to grow vegetables. It is actually not much different from the greenhouse in the previous life, so the effect is of course good.

Although glass is a valuable thing at present, the windows of Ning Rong's two palaces have long been sealed with glass.

If you don't pursue strict transparency and clarity like in your previous life, it's not difficult to get some glass.

The biggest secret of these five greenhouses is actually not glass and heating, but insulation layer built outside the greenhouse.

Using slag as the medium, supplemented with cotton and linen as the core, a layer of insulation layer is built against the wall, which can make the temperature of the greenhouse evenly rise to a high enough level and be kept.

Otherwise, simply relying on burning coal to drive such a large space will be too expensive, and it will be too extravagant by simply piled up money.

Secondly, if the burn is too fierce and the heat is uneven, it is easy to cause drying and charring near the stove, and the heat away from it is not enough.

And with this insulation layer, even the most primitive insulation layer plays an immeasurable role.

Coupled with the fermented livestock manure, this green vegetable has become the green gold mountain in Li Xuan's eyes.

"What I asked the prince to see is not this, the stove and radiator. The coal balls burned in the stove are those piled up. This stubborn intention can burn one piece for half an hour, and two pieces at a time can burn one and a half hours. The room is compact and not airtight, so it can keep it from being cold all night.

The coal squares on the market are far worse than this one. One dollar costs three cents. Ours only costs two cents per dollar. Four cents per night is not cold, and six cents per day is hot. It’s less than two hundred cents a month. Save a little, and more than one hundred is enough.

This price is very low, and it can be used by ordinary people.

With small profits but fast turnover, the Ministry of Internal Affairs will have a stable source of wealth that will never be exhausted and can benefit the people.

After all, there will always be winter, and at least a hundred people will die of freezing in the capital every winter.

I don’t know how many people died of cold infection and wind and cold.

Therefore, selling coal so cheaply is also the kindness of the Tian family to the people.

Moreover, not only can coal balls make money, but also stoves. Ordinary coal ball stoves are simple and don’t count as much.

The most profitable thing is this kind of heating.

This requires a skilled blacksmith to spend time on making it, polishing it little by little by little by little. Some devices require unusual tools. We promised in advance that only Delin can do these devices...

The prince said, would those great players like this kind of good thing not like?"

When talking about serious matters, Li Xuan was still very serious. He nodded and said, "Jia Qiang, it seems that I have taught you very well. I am close to Zhu Zhe Chi, and you have taken the initiative to make the Internal Affairs Office."

Jia Qiang nodded seriously and said, "If you get too close to the pig, you will inevitably have to spend more time."

Li Xuan laughed and scolded: "You are so good at playing football, and you scold me again, please be careful."

While he was joking, he squatted down, picked up the tongs beside him and picked up a coal ball, looked at it, and asked, "Jia Qiang, why are there eighteen holes on it?"

Jia Qiang said: "This is a big one, with eighteen holes, and a small one used by ordinary people, with only twelve holes. These holes are for ventilation so that the coal balls can burn more thoroughly."

Li Xuan nodded and said, "Good thing! It's really a good thing. I guess I think that the old man's mansion at home most likely likes this."

Jia Qiang smiled and said, "The stove is not inside and the outside is built. Not only the elderly, but most of the big-name households will like it. The heating effect is much stronger than that of smoked cages and braziers. The key is that it is cheaper. How much does coal balls cost? Where is charcoal?"

Li Xuan twitched the corner of his mouth and said, "Xixinsi of the Ministry of Internal Affairs cut down hardwoods in the mountains of Yizhou every year to burn charcoal, then transported them to the red basket, saw them according to the size, and woven small round jingle baskets, brush them with red clay baskets and fill them with red clay. Each piece is about a foot long and the garden diameter is two or three inches. It is fragrant and warm when burned. One pound can be burned for half an hour, grayish white without exploding, and there is no smoke. However, it costs thirty cents per pound!"

Fifteen times that of coal briquettes.

However, Xixinsi had a more resounding name in his previous life: the inner factory...

"Tsk!"

Li Xuan sighed and said, "Jia Qiang, I know you can make trouble. Everyone says you are Shancai Jintong, but I still underestimate you. You are so capable of making a living..."

Jia Qiangqi said: "The Interior Affairs Office has added such a big investment. Is the prince unhappy?"

Li Xuan smiled bitterly and said, "It's not that I don't like it, but, do you know how many people are there for Hongluo Charcoal and Yinfrost Charcoal?"

Jia Qiang sneered, "Feed a bird's feather! The prince knows why the people hate the extravagant life of the powerful and noble families? That's because they rush the people to drive away like cattle and horses, serving them and enjoying them, but they have no favors to the people. This has been the case since ancient times, otherwise how could "The Charcoal Seller" come from? But the coal mines in the Ministry of Internal Affairs cannot do this, and they must repay the hard work of the craftsmen and civil servants. This is not only the prince and my moral conscience, but also the face of the Tian family."

Li Xuan frowned and said, "I'm not talking about this. What I'm talking about is how many giants have been fattened in this family and how many powerful people have! Jia Qiang, we are both funny and show off. Others will give in to us and will apologize for us. At most, they will curse in their hearts. But if they cut off their wealth, they will still have such a big financial way. Do you believe that they dare to kill people? Those group of Forget Bashes have already ambushed and killed an embroidered and robbed the commander of the Embroidered Guard, and it was Wei Yongming who escaped. You may not have the great fortune of him... Even the Master may not be able to live in peace. Why? "

Before he finished speaking, Li Xuan threw the fire tongs to the ground.

Jia Qiang patted his shoulder and smiled and said, "Prince, if anyone wants to murder, his first target must be me. Are you sure about this?"

Li Xuan nodded, looked at him squintly, and said, "You are not good either. Although I like to make some money, I want you to help you, but I didn't let you fill it out with my life?"

Jia Qiang was moved and laughed and said, "What are the prince thinking? In order to make some money, I still need to exchange my life?" As he said that, he looked back and Li Yong, the butler who was following behind, hurriedly stepped forward and asked, "What do the marquis want?"

Jia Qiang said: "Get a few potatoes over and get two more small pieces."

Li Yong hurriedly prepared, but soon returned. After Jia Qiang divided Li Xuan a small piece, he sat down himself, opened the small page at the bottom of the stove, and put the potatoes into the coal ash one by one...

The stubborn idea of ​​potatoes has been introduced to Dayan for many years, but it has not been widely promoted, so is corn.

In a relatively extremely conservative society, the spread of any new things will basically not be popularized without official promotion.

After all, tax collectors don't charge these...

Jia Qiang has made the Jia family's name more farms in the past two years and kept them more. When the new policy is launched, Lin Ruhai will promote the world and help the common people's suffering.

Bake the potatoes into the stove, he closed the door page and chuckled softly: "Although I am not willing to do this job, since I have taken it, I cannot hold back and embarrass my husband, let alone, there is also the love between the emperor and the empress, right?"

"The incident in Yangcun in Wuqing shows that there are indeed big gangsters lurking in the secret in Beijing, and they can even mobilize the army, which is very terrible!"

"Although, the advice given to me is to respond to changes in the same way and wait for the opportunity..."

"But I think this matter is too passive. The prince only knows that if we move their Hongluo Tan, they will be murderous, but he doesn't know what kind of interests the emperor and his wife will implement the new policy. A drop in the bucket is not considered a waste of money before this interest!"
To be continued...
