Separated from Ji Shangshu, Zhou Jingxian came to the palace gate, and before she could speak, the guards who had just put on an indifferent face once again showed a smile that was even brighter than when she saw King Kang and Ji Shangshu, which made Zhou Jingxian feel too ostentatious and a little unaccustomed.

"Xian County Lord to meet Your Majesty?"

"Yes, it's because ......"

"The little one will report to you, and the county lord will wait."

“……”

Zhou Jingxian, who couldn't tell the reason, watched the guards leave quickly, and counted the time silently in her heart.

Before he could count to a hundred, the guards ran back out of breath, and said as they ran: "Lord Xian, please come in, Your Majesty is now in the imperial study, and I am very happy to hear that you are coming." ”

Happy?

The corners of Zhou Jingxian's mouth raised slightly, and she said in her heart: When Grandpa Huang sees me coming, even if he is not happy, he will become very happy.

Because, she brought good news for Mr. Ning!

When you enter the palace gate, there is a special person in front to lead the way.

The guards and maids in the palace seemed to be very happy, with an excellent attitude, and they were busy shushing and asking for warmth, the reason for this, Zhou Jingxian knew, but she didn't know that everyone's attitude was only slightly better before, why did they have a stammering meaning now.

The father and the uncle of Jin are competing for the position of the crown prince, and it is clear that there is no conclusion yet, even if this group of people is high and low, there is no need to be so fast.

Could it be her delusion?

"The county lord is careful of your step."

Finally, in the sound of compliments, Zhou Jingxian came to the imperial study.

As soon as she entered the imperial study, she closed her eyes by the strong light, and finally adapted to the light in front of her, and when she opened it again, the scene in front of her made her quite speechless.

I saw that on the bookshelf of the emperor's grandfather, there was a glass cup on each layer.

They come in a variety of postures, including a transparent plum bottle, an opaque glass box, and a new glass gourd.

Even on the top of the shelf, a translucent glass arrow can be seen.

This not only made her wonder if Grandpa Huang had nothing to do and drew a lot of design drawings to make things difficult for those new craftsmen, so that he had the current bookshelves with all the bells and whistles.

"Jingxian girl, you came just in time, the Ministry of Industry sent the first batch of glazed ornaments, the glaze that I let them try, take a look, is it good?"

Zhou Qian was like a child who had just gotten a novelty toy, showing off what he had gained on the shelf.

In the past, these glass bowls cost at least a million taels of silver.

Now it's on the shelf.

Although the cost plus labor price was less than one hundred taels, Zhou Qian still felt like a treasure.

Especially the speed at which he drew his own drawings and let the craftsmen fire them quickly, Zhou Qian was most fascinated by them.

So no matter whether it looks good or not, Zhou Qian filled all the bookshelves with a glass cup in one go, so that the courtiers can also see the craftsmanship of the royal craftsmen when they come in, and they can be more confident in the firing of the Daxing royal glaze.

"Grandpa Huang's arrow is very beautiful, but it doesn't look good on it so bare, why don't you fire another bow, and then ask the carver to make a wooden shelf and put it up?"

Zhou Jingxian knew that she didn't have any sense of art, and she knew that she was easy to shoot on the horse's legs, so she simply picked up the objects she was interested in.

Zhou Qian glanced at the glass arrow he placed in the most conspicuous place, thought for a moment, then nodded, and praised: "This proposal of the Jingxian girl is good, I will draw another bow." ”

Zhou Qian said and walked quickly to the side of the low table and sat down, just picked up the pen, suddenly thought that Zhou Jingxian should be resting today, and deliberately came at this time, I was afraid that there was something important, I patted my forehead lightly, and secretly said "happy and confused", and then gestured to the futon in front of the short table.

"What's the matter with Jingxian girl, sit down and talk about it."

Seeing this, Su Peiyuan hurriedly sent someone to serve tea.

Seeing that the shorter who was closest to the important news of state secrets, he finally had a new candidate for the seat after the former prince.

Even the palace maids and eunuchs who served in the imperial study knew what to do.

Although I don't know the preferences of the county lord, I still presented His Majesty's favorite tea.

As soon as Zhou Jingxian lifted her robe, she sat opposite the low table without any scruples, and went straight to the topic.

"Grandpa Huang, Mr. Ning has invented another good object."

This sentence directly made Zhou Qian stunned.

He also thought that Zhou Jingxian came this time to say how Ning Wuxian's injury was, but he didn't expect to come up and give him such good news.

"Good things? How good is it?! ”

Is it as good as steamed wine and glass?

Of course, Zhou Qian's later words did not ask, because he felt that if Ning Wuxian, who was a big handful of them, such as colored glass and steamed wine, was to be arrested, Ning Wuxian was not a human, but an immortal.

Rao is like this, Zhou Qian feels that with his granddaughter's judgment, since it is a good thing, it is definitely not an ordinary thing.

"It's something to keep warm."

Heating?

Charcoal?

At this time, the tea was served.

Zhou Qian saw Zhou Jingxian pulling something out of her sleeve, and poured a cup of hot tea for her precious granddaughter herself.

Between grandparents and grandchildren, it was a very ordinary move, but in the eyes of those who served Zhou Qian, it was like an earth-shattering shock.

Many people have already begun to think, and when they get off duty, they will send someone to the people who serve Emperor Jing's concubine to make some new friends, and there will be a new way to go in the future.

The party Zhou Jingxian didn't have so many ideas, so she took out the drawings, and saw that she didn't know who put the teacup in front of her and blocked the way, so she pulled it aside.

When Su Peiyuan saw this scene, the smile on his face froze, and he was about to make a reminder, but His Majesty glanced at him, and he could only swallow back the words full of reminders.

"Grandpa, look, these pictures are specially made for your palace, these pictures are made by Mr. Ning to my county lord's mansion, he said that this is called a radiator, after the hot water boiled by the boiler enters the heating pipe, it can be dissipated through the radiator, which can replace the charcoal fire."

While thinking about what Ning Wuxian said at that time, Zhou Jingxian added some of her own understanding, and tried to explain it clearly to Zhou Qian at one time.

After finishing speaking, he was afraid that the imperial grandfather would worry that these radiators would consume too much iron ore, so he pointed at those radiators again.

It is said that the craftsmen should cut the amount of iron and fill it with other impurities that can conduct heat and dissipate heat.

"Anyway, as long as the hot water can be circulated, this set of heating can be used for many years, don't look at the early investment cost is very high, but according to the consumption of charcoal fire, the cost can be leveled in less than two years, and the rest is saved, the most important thing is that it does not smoke, the pot for boiling water, and you can also use these fires to cook, killing two birds with one stone, and if the wood is used to burn the fire, it can also save a lot of wood."

After Zhou Jingxian finished talking about the advantages of using heating, she asked tentatively.

"Grandpa, do you think this heating is a good object?"

"Count!"

Zhou Qian replied loudly.

"With this heating, the consumption in this palace will be reduced a lot in the future, and there is no need to use the charcoal fire that is not divided into three, six, nine and so on, the most important thing is that the cough that is easy to recur in my winter, stained with its light, should be reduced a lot, hahahaha!"

Zhou Qian's laughter was hearty.

The big move caused by the expansion of weapons after the increase of troops may be considered a waste by the courtiers.

Now, under the pretext of burning heating, tens of thousands of catties of iron are pulled from the new iron ore pit exposed by drought in Yibei Province, who will refuse?

In particular, the drawings of this set of heating were in his hands, and he could sell them and make a fortune for military supplies.

"Ning Aiqing is really my cornucopia!"
