Li Shen was at a loss for the birthday gift given to Wei Guifei, and began to think in a circle around the courtyard in a donkey-pulling style.

If you can't even think of it, it's the same as in previous years, because there's a lot of stuff in the treasury anyway.

Lu Dingniang looked at herself, and Lang Jun was also helping to find a way around the yard.

But with her vision and knowledge, she couldn't think of what to give.

Li Shen kept thinking about it at night and didn't think about it, so he had no choice but to think about it tomorrow, and after the two of them took a bath that night, they lay on the bed and thought.

Lu Dingniang sat in front of the dresser to sort out her undried hair.

Li Shen inadvertently looked over, and suddenly had a flash of inspiration,

yes, how did you forget this,

In fact, what Li Shen thought of was very simple, when he saw Lu Dingniang arranging his hair in front of the bronze mirror, he suddenly thought of the mirror.

Because of the Shenzhu incident, Li Shen did not produce glass on a large scale in order not to be suspected. However, the glass workshop has been producing and researching,

For example, making utensils and utensils, or researching and producing better and larger glass.

It's been a year, and there should be some results.

Just do it, the next day Li Shen got up and took a large number of people, including Lu Dingniang, to his imperial village.

First, in order to let Lu Dingniang get familiar with Huangzhuang, and secondly, to let the people in Huangzhuang get familiar with his housewife.

This season's grain has been harvested, everyone is idle at home, when they learn that the prince is coming with the princess, the people of Dahuangzhuang come to the village to greet them.

"See the princess."

A group of people saluted Lu Dingniang, the little girl was a little restrained, how could she have seen so many people to meet her.

Li Shen patted Lu Dingniang's little hand to comfort him, and then said to the village chief: "Zhang Da, there is nothing wrong with Zhuangzi recently, right?" ”

"Don't worry, Zhuangzi is fine, and three men have just been added in three months."

Zhang Da responded,

"Oh? That's a good thing, how much has been added this year? Li Shen is very happy about the population growth.

"Back to the prince, Dahuangzhuang has added twenty-two men this year. There are fourteen men in Xiaohuangzhuang, and the other two guards are Zhuangzi Tianding, more than forty. Zhang Da replied.

"What about the girl?" Li Shen frowned, Li Shen is not a patriarchal ideology in this era, everyone is a productive force.

"This... There should be more than a hundred. Zhang Da replied uncertainly

Li Shen has 1,300 households in his hands, as well as the family members of the guards who have not been on the wheel of the food, a total of more than 2,000 households, divided into four Zhuangzi.

"Zhang Da, this king wants the population, male and female babies are the same, how to increase the population without female babies, what this king wants is detailed information, how many male babies, how many female babies.

Forget it this time, next time you're like this, don't do it as the main bookkeeper, this king can find someone else to do it. Li Shen said with a gloomy face,

"Lord forgive the sin, the villain must be more detailed next time." Zhang Da saw Li Shen lose his temper and hurriedly confessed.

In fact, this can't be blamed on Zhang Da, patriarchy is still relatively serious in this era of openness, and it will be more serious in later generations.

"Zhang Da, inform all Zhuangzi, male and female babies are the same, this king doesn't care what the etiquette system is, this king only needs the population,

If you want to sell or throw away the doll because you can't afford it, let the king know that it will be distributed to the northwest, and if you can't afford it, you will report it to the palace, and the palace can adopt it. Hear no!! ”

In fact, Zhenguan rarely sells or throws away his children, because there are few people in the land, but Li Shen still has to take a preventive shot.

"Yes, lord." Zhang Zhanzhan replied tremblingly,

Li Shen took Lu Dingniang around the village, and then went straight to the secret glass factory behind.

Since the glass windows were not mass-produced, there were only three craftsmen, who had previously been in charge of firing porcelain and later cement, and this time they were arranged to burn glass.

"How's the research going?" Li Shen asked one of the people in charge with a smile.

"Back to the prince, the three of us are much more proficient now, and we have also studied the glass-blowing method that the prince said. The prince came to take a look. ”

As he spoke, he led Li Shen to the warehouse.

"Wow~~~"

Several of the maidservants screamed.

There are glass products of various shapes on the shelves inside, as well as utensils, such as plates, bowls, wine glasses, teacups, etc.

There are also ornaments.

Several women loved the shiny things and stepped forward to check, touch this, and look at that.

Li Shen also stepped forward to take a closer look.

"These can't be done, we have to go back to the furnace and rebuild,"

Although these look beautiful, they are flawed for people like Li Shen who have seen the glass products of later generations.

For example, the plate is not so round, the walls of the wine glass are uneven, etc.

"Lang Jun, this is already very good." Lu Dingniang said with a vase.

"Worse. We want to make high-quality products and make money for the rich. Li Shen said to Lu Dingniang with a smile

Then he turned around and asked again

"Did I say flat glass?"

"Go back to the prince and make it, come with the villain." The steward said and took Li Shen to another warehouse.

There is a lot of flat glass here. And they are all separated by animal skins, both large and small.

Li Shen looked at the largest one meter and a half square. Now their process and ingredients are not good, and the glass that is too large will be deformed and will shatter at the slightest twist.

"Did I make the glass knife you made?"

Li Shen had bought some diamonds from merchants in the Western Regions before, and diamonds had not yet been defined as a luxury item at this time.

The diamond that Li Shen bought was used to make glass knives and use the whole diamond.

"Go back to the prince, and make several handfuls." After speaking, he took it and showed it to Li Shen.

"Okay, give me the big one in two, I'll be useful." Li Shen said.

Now that glass is available, the rest is much simpler, and the easiest way to make a mirror in this day and age is to react tin with mercury.

These things are very easy to find, even in Taoist temples.

Although it will be poisonous when it is made, Li Shen plans to build an open factory to let the poisonous gas volatilize as much as possible.

And Li Shen is going to let the cotton workshop make some thickened masks. Of course, Li Shen was also going to get back some Tibetan prisoners.

The materials were insufficient, and Li Shen also needed to go back to prepare, and he also needed to apply to Li Shimin for some Tibetan prisoners to work.

So Li Shen took people and left.

He needs to go back and get people to prepare things,

Tin was a metal that existed before the Han Dynasty, so it wasn't difficult to get by, and as for mercury, it was easier.

The only problem is the proportion, how to do it best.

For the ancient feudal society, the privileged class made Li Shen feel really good, as long as he moved his mouth, he would do things for you, and it was super efficient.

The day after Li Shen finished talking to Wang Hongfu, all the things Li Shen needed were ready, and Li Shen went to the cotton workshop to let them make a few masks with more than ten layers, and then returned to the glass kiln to start the experiment.

Of course, for Li Shen, who is afraid of death, it is all remote command. For him now, the biggest tragedy in life is that people die and money is not spent.

(In the section of making mirrors, don't use the old iron, at least I wrote out the raw materials, and don't get tangled in the process.) I almost wrote about mirror reflection or transpiration.

But in fact, this method is the simplest, spread tin foil on the glass, pour mercury and become a mirror. Of course, ignore the poison gas and arrange for the Tubo people to do this work.

Kneel and thank you. ）
