"Good! But I heard that the stone grease water is very smoky, what about after refining? "Wu Zetian said.

"Aunt Qi, to tell you the truth, this kerosene and diesel lamp is indeed smoky, and it is not comparable to a candle.

However, the stone grease water is inexhaustible, and the number of candles is limited, even in the palace, and the number is not too large to control the use. Most of them still use oil lamps.

However, today's oil lamps mostly use tung oil and sesame oil, and the price is not cheap. Comparatively speaking, even if the kerosene and diesel fuel of Sun Er were transported from the east of the river to Luoyang along the big river, each bucket was ten cents cheaper than tung oil. ”

When Wu Zetian heard it, since it was so cheap, of course he could use it.

"This mining matter, although it is the specific charge of Shang Fangjian, but the affairs of the mountains and rivers in the world are also under the supervision of the winter official, since this fierce fire oil is so good, all armies must be deployed.

You draw up a plan, and I will let the prime ministers discuss it, and then send the Xia official (military department) to implement it. That's the main purpose of my stay today. ”

"Yes! Grandmother, the oil lamps and lanterns used in the palace today are quite inconvenient. The grandson made improvements to both of these things. Another day, the grandson brought it to the grandmother to see. ”

"Good!"

……

Zhuojun Palace.

Today is the joy of Wu Yan's housewarming, and there are many officials who come to cheer. Yao Kuan and Yu Fei had already served as deputy pawns, leading the guards given by the emperor to the king of Zhuojun, and the pawn army was temporarily vacant, and Yao Kuan was in charge of the overall responsibility.

The Prince's Imperial Guard has more than 300 people, each with two chief and deputy guards. The two pawns are from the top of the fifth rank, and the two deputy pawns are from the top of the fifth rank, and they are both high-ranking officers.

This housewarming joy is not a matter of whether Wu Yanzhi wants to do it or not, but it must be done, which is in line with the etiquette at that time. As for the acceptance of some gifts, it is in accordance with the regulations, which is very different from later generations.

In the afternoon, many officials were drunk after eating. At the time of parting, Wu Yanzhi presented a horse lantern to each official.

"What is this?" Many officials can't figure it out.

"This is called a horse lantern, Wang Langzhong, please take a look, there is a little next to it!" Because there were many officials who came, there were nearly 200 people. Yao Kuan is specially responsible for delivering horse lanterns to them.

This lantern has just been manufactured, there are 300 in the early stage, and the cost of each lantern is actually less than 500 yuan. However, because transparent glass was very expensive at that time, the lantern happened to be made of transparent glass, so it was very valuable at the time.

The structure of this horse lantern has been introduced earlier, so I will not repeat it here. Roughly speaking, a glass cover is put on the outside of the oil lamp, and then fixed with a shelf, and a rope can be tied to it.

The real horse lantern in later generations only existed more than 200 years ago, and it was also a luxury at that time.

If you want to talk about the market price, thirty or fifty yuan is required, where have those officials seen this thing!

"Senior Wailang, if you have this thing in the future, you will not be afraid of wind and rain when you go to court, and no matter how big the wind and rain are, he will not extinguish it." Yufei also introduced it on the side.

"I think so, you see this glass, so transparent and flawless, how can you buy it without seventy or eighty times?"

"Yes, the king of Zhuojun is really generous, and it will cost more than 10,000 yuan just to send us this horse lantern! We have to thank him! ”

"There is no such thing in the palace at present, and the king of Zhuojun is really willing to do it."

The praise of "......" is endless.

Of course, although the cost of this thing is low, the market price of 200 horse lanterns is indeed worth 10,000 yuan.

Wu Yanzhi didn't want to leave the impression of a miser. Although he did receive tens of thousands of yuan in gift money today, he almost repaid half of the gift.

He is now the king of the county, and the income of 800 closed households a year alone has seven or eight thousand, which is nothing.

What's more, this thing has to be produced on a large scale, plus the oil is provided by itself, and it is not too easy to earn tens of thousands of yuan a year.

Watching the hundred officials happily take the lantern and leave, Wu Yanzhi's sense of accomplishment arose, this is not something that can be bought with money!

I came to Da Zhou, and finally made some achievements, although it is still very far from my expectations, but in the eyes of ordinary people, it is close to the peak.

This is Qi Xuan coming over and saying: "Lord, I see that in the afternoon, the prince will enter the palace and send the lantern into the palace, and the emperor must use it first." He reminded.

Wu Yanzhi smiled slightly: "I have already sent someone to send thirty lights in yesterday, and I will bring a few special horse lanterns in later, which are specially made of brass and add some special decorations, which are extremely exquisite." ”

When Qi Xuan heard this, it seemed that he was overly worried, how could the prince not think of these simple things?

"Later, you can bring four of them, this thing is really useful. Also, I also prepared 300 catties of oil for you. If you run out, you go to them. "Wu Yanzhi is very concerned about his capable subordinate.

"Thank you for the reward! In addition, the prince has to find a way to deal with Lai Junchen, and he heard that he has gone crazy recently, and he is eager to make meritorious contributions, so he actually wants to deal with the two princes of the imperial heir and the martial family, and he is also fighting the prince's idea. Qi Xuan's expression was a little melancholy.

Wu Yan listened, it seems that Junchen is really crazy, and the people of the Wu and Li families have to deal with it, isn't that self-destruction?

"Don't worry about this, I'm going to let this person die without a place to be buried!" Wu Yanzhi smiled coldly.

……

Luoyang Palace.

Wu Zetian looked at the nine golden lanterns sent by Wu Yanzhi, one of which was already lit. She nodded happily: "It's not bad, with this thing, you won't be afraid of wind and rain." ”

Wu Yanzhi said: "That's true. Sun Er estimated that there must be a great demand in the palace, and he had already ordered the workshop to hurry up production. ”

"Horse lanterns should be expensive, right?"

"The main thing is that this glass is very expensive, but I have already told the producers that the price of those sold in the palace is far lower than the market price. This horse lantern has just come out, the supply exceeds demand, the market price is fifty yuan, and there is no goods for the time being. Wu Yanzhi said.

"For such an expensive thing, there are not too many in the palace, just a few hundred lights. After the price drops in the future, it is not too late to equip it in large quantities. ”

"The grandson thinks the same thing." According to Wu Yanzhi's meaning, the horse lanterns purchased by the palace are only sold for fifteen yuan each, and this thing is not good if it is sold cheaply.

"Grandson, how is the maintenance of Shangyang Palace going?" Wu Zetian is very concerned, she likes to work in Shangyang Palace.

Although it was flooded this time, it is a very rare event after all, and in the future, in case of floods, you can withdraw in advance.

"Sun Er has basically completed the restoration plan, and has ordered the winter lawsuit and the personnel of the supervision organization to discuss the plan.

The grandson had already visited the Shangyang Palace many times, and decided to rebuild a taller palace using steel and cement.

This palace is magnificent, nine stories high, straight into the clouds, overlooking the entire divine capital. It is expected that the high-rise building will take two years to complete.

Although this high-rise building has been given a good name, it is called Long Live Immortal Palace. This is the pattern, please grandma preview. Wu Yanzhi asked the painter to copy the pattern he designed and presented it to Wu Zetian.

Such a big project must be approved by the emperor, and it doesn't matter if you say it alone.

Wu Zetian took the pattern, looked at it carefully, and felt a burst of ecstasy: "Very good!" In the Long Live Immortal Palace, it will be built, and I will live in it every day! "Please Baidu "Throw Book Network" Thank you for your support!
