"It's a radiator."

Ning Wuxian saw the doubts in Zhou Jingxian's heart, and moved her body in her direction on her stomach, explaining the role of the radiator in a language she could understand.

"Use a stove to boil some hot water, and the hot air brought out by the flow of hot water can be bridged and dissipated through it to warm up the room, and after having it, the heating does not have to be so dry, and it will be warmer, as long as the hot water stops, it can always be warm."

And such a good baby?

Zhou Jingxian is actually not used to lighting charcoal fires in winter.

One is that she practices martial arts all year round and doesn't feel how cold it is, and the other is that no matter how good smokeless charcoal is, if it burns for a long time and smells for a long time, the wings of her nose are also dusty, and she needs to be scrubbed from time to time, which is a burden to her.

But if there is such a heating method as Mr. Ning said, she thinks that she will burn this radiator when she sleeps, and she would like to try it.

Especially when the imperial grandfather killed the enemy in the north, he was injured due to the cold weather, but if he lit the charcoal fire, it was not good for his health, resulting in always coughing, therefore, the concubines in the harem, almost everyone would stew pear soup for the imperial grandfather to drink, and among them, the pear soup stewed by Emperor Anhuang Guifei was the most suitable for the taste of the imperial grandfather.

But the pear soup was drunk too much, and the doctor said that it was easy to have a cold stomach.

If you have radiators, then all these problems can be solved!

"Mr. Ning, how is this radiator made? Is it enough to follow the drawings above? ”

Zhou Jingxian did not hide her eagerness and told the situation of the emperor's grandfather.

When Qin Shi next to him heard the radiator, he was only surprised by Mr. Ning's whimsy, and he didn't think about His Majesty's physical illness at all.

At this time, when he saw the Xian County Lord, who usually did things roughly, the first thing he thought of was His Majesty, and he secretly decided in his heart that when he reported today, he had to talk about this matter with His Majesty.

The filial piety of the county lord is not on his lips, but engraved in his heart.

After listening to Zhou Jingxian's words, Ning Wuxian knew that the audience of radiators could be expanded.

But.

There is one issue that needs to be addressed urgently.

That's the problem of wasted consumables.

"County Lord, I haven't been to the palace yet, but I think that the place where His Majesty lives should be more empty than ours, like this device full of radiators is not suitable for the palace, I plan to build a set of radiators suitable for the main courtyard and main wing of the Xian County Lord's Mansion first, and then debug the temperature on the spot, if it is appropriate, I will make modifications and customize a set for Your Majesty, what do you think?"

Speaking of this, a flash of inspiration flashed in Ning Wuxian's mind.

That's right.

In an open house, radiators can be installed at fixed points.

As long as it is placed in a place where people are concentrated, and all the rest is made into iron pipes to transport water, in this way, the number of iron tools used will be reduced.

If he follows this line of thinking, he can make some small radiators, and the cost of each is controlled within ten taels of silver, and then make the pipes more fine, so that some people who are afraid of cold and illness can also grit their teeth and afford to use this thing.

Right!

That's it!

Ning Wuxian saw Yun Fei who was going to the kitchen walk in the door and hurriedly greeted him.

"Yunfei, go and bring the pen and paper, and I'll draw another set of design drawings."

"County Lord, in this case, those scraps in the warehouse may not be enough, so I can only trouble you to go to the Ministry of Works, and then borrow some ironware, not too much, two hundred catties are enough."

"Invite two more porcelain craftsmen, I have something to ask them."

Today's ceramics are mainly a delicate but not down-to-earth.

In order to reduce the cost, it is necessary to let those craftsmen think about it carefully.

It is best to figure out that under a certain water temperature, the ceramics will not crack after being dyed for a long time, and if the steel can be hotly cycled, then the iron ware that ordinary people cost ten taels of silver can be replaced with three or five taels of silver in the future.

The melting point of the quartz sand used to fire the glaze is very high, and I don't know if adding quartz sand can achieve his wishes.

Thinking of this, Ning Wuxuan sighed.

"Why is Mr. Ning sighing, but where is it uncomfortable?"

Still waiting for breakfast, Zhou Jingxian, who went to the Ministry of Industry to find someone again, couldn't help but get nervous when she heard his sigh.

"If Mr. Ning is tired, don't think too much, it's important to rest."

"No, I'm not tired, I think I've been a little lazy lately, so I haven't been able to improve the radiator, county lord, if you are free, in addition to going to the Ministry of Works, go to the palace again, and inform Your Majesty about the radiators, not to mention every household, even if ten households use radiators made by the Ministry of Industry, I think it is also a lot of income."

Ning Wuxian's original intention was not to make money with radiators.

Thanks to Zhou Jingxian, he forced him.

But in the follow-up development, he is really powerless, and it is impossible to see him enjoying the heating himself and letting others freeze.

So.

I will dedicate this idea of making money to Your Majesty, and let Your Majesty solve the problem of technology and cost.

As for promotion, don't worry.

As long as the hierarchy is divided to meet the needs of different income groups, there is such a heating artifact, and those who can use it will actively choose to use it.

"By the way, there is also a stove for boiling hot water, it doesn't have to be dedicated to boiling hot water, it can also cook rice, and the radiator is small, and the stove can also be smaller."

Ning Wuxian redrew it on the paper twice.

In the end, he stuffed the drawings into Zhou Jingxian's hands, pillowed his hands under his neck, and looked like a shopkeeper.

"I'm just putting forward an idea, and I want Your Majesty to give me a few sets of radiators for free, and let the craftsmen use their imagination to solve the actual problems themselves."

The usefulness of some utensils in this era is still different from what he knows.

A person's cognition is always limited, so there will be a brainstorming theory.

Coupled with the fact that he has a specialization in the art industry, he may feel that the problem that needs to be overcome by overcoming heavy difficulties is not a problem at all in the eyes of those craftsmen.

Zhou Jingxian took those drawings, opened her mouth, and finally stood up directly.

"I'll go into the palace now and tell the imperial grandfather about it, and it will be faster for the imperial grandfather to dispatch the craftsmen of the Ministry of Works."

"Aren't you going to eat breakfast, county lord?"

"I'll just have some pastries in the wagon."

After Zhou Jingxian finished speaking, she didn't even put on her coat, and rushed into the cool autumn breeze in a hurry.

Ning Wuxian looked at the blurred figure outside through the window, and let out a sigh: "What a good girl who is filial, but this paper window is too pasty, and it is not good to look at the scenery outside, just when the craftsman comes, let them take the time to replace it." ”

Qin Shi heard that Mr. Ning was still praising the filial piety of the county lord in the last sentence, and planned to change the paper window in the next sentence.

He glanced at the paper window, which was obviously newly replaced, and suddenly felt that Mr. Ning was really idle and had nothing to do, so he would toss around.

Can this paper window be replaced with any tricks?

At most, the flowers and birds on the paper are replaced with fish and insects or other patterns, isn't it still paste?

Could it be that if you change the new window paper, you can directly see the scenery outside?
