(Thank you for your pure mistress!! Monthly tickets for your friends late summer and autumn., two monthly tickets for your friends frb9898~~)

The Haizhou City under the night is peaceful and quiet. Although the winter night is cold and windy, the room is full of spring. Gao Guiying lies in Li Xin's arms satisfied, her face is like peach blossoms, her breathing is sometimes tight and sometimes fast, and her starry eyes are full of love.

As a woman over thirty years old, she cannot have children and has long fallen out of favor in other people's homes. However, Li Xin treats her as usual, allowing her to enjoy the joy that women should have again and again.

Gao Guiying hugged Li Xin with gratitude!

"Sister Guiying?"

Li Xin asked in confusion.

Gao Guiying raised her pretty face and murmured, "Mr. Li, I am old and can't have children, and I don't have any feminineness. Why are you so kind to me? I don't feel real at all, I'm afraid that I'm in a dream and only realize I'm alone when I wake up from the dream."

Li Xin secretly sighed that, by the way, Gao Guiying and herself have paid more. She got up early and touched the gang to train cavalry, and had no status and was willing to be a mistress. What she paid was nothing more than working hard in bed and often sleeping with Gao Guiying. For men, this is not considered a sacrifice.

In modern love theory, there is a view that the more you give, the more you cherish it. When a man and a woman get along, if one party gives more than the other, then the love for the other party will be greater. This is like investment. The more you invest, the less you can stop. Although feelings are much more complicated than simple investment, the principles are the same, not to mention that a person’s life span is limited. What you put in love is not only energy and money, but also youth that cannot be bought back no matter how much money you have!

This is particularly obvious in women, because women have a shorter shelf life than men.

Li Xin didn't know if Gao Guiying had this kind of mentality. When he recalled the efforts of both parties, he couldn't help feeling guilty and smiled and said, "Sister Guiying, I like your hot and powerful taste, so I snatch you from Li Zicheng's hand. If he doesn't cherish you, it's because he is blind. Don't worry, I will treat you well for the rest of my life."

"Young Master Li!"

Gao Guiying's voice choked.

"Don't cry, don't cry, why do you cry at any time? Women will get older if they cry often. Come on, give me a smile!"

Li Xin thoughtfully wiped the tears from the corners of Gao Guiying's eyes.

"Hate!"

Gao Guiying burst into laughter and pounded Li Xin a few times as if she was acting coquettishly.

Not to mention, a mature woman like Gao Guiying acts like a child, and looks like a pear blossom with rain. In the strong contrast, Li Xin was stunned.

Gao Guiying said happily: "Mr. Li, when are you going to put Huiying in the room? When we came, the matchmaker had already told me that it would be better to always let Huiying follow you without any name or share. Please take it early."

"How do you resolve your relationship with Huiying?"

Li Xin asked.

Gao Guiying gritted her teeth and said, "I am not her mother, I just adopted her, and Huiying can call me sister in the future."

"Aren't you jealous?"

Li Xin asked again.

“Oh ~~”

Gao Guiying sighed: "You men, you are obviously thinking in your heart, and they are still hypocritical. If I say I care, will you let Huiying go?"

Li Xin smiled.

"If you treat me well, I won't be jealous!"

Gao Guiying beat Li Xin again.

"Okay, I'll continue to pay the public grain!"

Li Xin spread his arms and pulled Gao Guiying onto him!

"Who gives it to whom!"

Gao Guiying muttered dissatisfiedly, but there was a smile in her eyes!

...

The next day, Li Xin took people out to find a larger quartz mineral. As the origin of crystals, quartz minerals are not difficult to find. After two days, Li Xin found a large piece of quartzite, and then asked someone to collect quartz, grind it into powder, set up a stove, pull up a bellows, and then asked someone to send soda ash, limestone and feldspar powder, and put it in the kiln for calcination.

Feldspar is the most common type of rock, accompanied by granite or unknown rocks on the mountain. It has a cyan or pink appearance and is more convenient to mine.

The melting point of quartz is 1750 degrees, while coal can only provide a high temperature of 1400 degrees, which is not enough to melt quartz. Therefore, feldspar needs to be added, which is rich in sodium and potassium, is easy to melt, and plays a role in melting.

Although feldspar is insignificant, adding feldspar to firing glass is a milestone application. Most of the glasses in the European Renaissance were purple or cyan, which is related to the low firing temperature, the impurities cannot be purified, and the lack of knowledge on adding feldspar.

The fire spit out a flame tongue about a foot high, and the bellows were whistling. The mixed solid in the furnace gradually melted into a viscous transparent liquid, and a thin layer of impurities gradually precipitated at the bottom.

"It's out!"

A master called out a sudden shout. Several young men immediately stepped forward and wrapped the handle with a thick wet towel to make it half-invert. The glass liquid was poured from the mouth of the stove into the ceramic mold. Then someone brought it to the mill and pushed it straight over with the mill to crush the liquid.

As the temperature drops, craftsmen carefully smash the pottery mold. A piece of two-foot square flat glass appeared in front of them. The surface was as undulating as ripples, and clear wrinkles were visible inside, densely packed, and fine lines were distributed, which was obviously related to the strangeness of the pulling technique.

However, the glass is transparent, which is the only good, and it also shows the quality of the East China Sea quartz mine from the side.

The craftsmen all knew that the firing failed, so they lowered their heads and kept silent.

"Continue, practice makes perfect, and strive to master the rules!"

Li Xin didn't say much and waved his hand.

Two days later, after nearly a hundred firings, a completely transparent flat glass finally emerged. Of course, due to the technology, it is still different from the glass produced by modern assembly lines. After all, it is hand-made, with a slightly undulating surface and an absolutely uniform thickness, and further polishing is needed.

However, overall, Li Xin was very satisfied with the light transmission, no color cast, and the character was not deformed.

"This is the glazed plate!"

Hui Jian and Hui Qiong carefully held the glass plate, looked left and right, unable to let go of it, and the rest of them were amazed with stuttering sounds.

Li Xin also looked at it with his hands and said satisfied: "It's good, but it needs further improvement. Remember the process and make a few more pieces, and you can get a lot of people."

Shao Shixin bowed and said, "Don't worry, Commander-in-Chief, there are so many people in Xiao Yuan camp, there is always something that can be used, and then recruit people from the local crystal craftsmen."

"Yeah~~"

Li Xin nodded, but suddenly thought of something and said, "Get some mercury and tin!"

"Get orders!"

In a moment, a craftsman took the mercury and tin, heated and melted according to Li Xin's request, applied it to the side of the glass, and made a pair of mirrors.

"Yeah, not bad!"

Li Xin looked at himself in the mirror, very clear, the characters generally do not deform, and further polishing is needed.

"Huiying, look?"

Li Xin handed over the mirror again.

Huiying looked in the mirror and was shocked. Is this himself?

After all, no matter how smooth the bronze mirror is, its translucency and brightness are not as good as the glass mirror. Huiying looked at herself in the mirror, with curved eyebrows, smiling at the corners of her eyes, small cherry mouths, red lips and white teeth, clean skin, and a faint blush on her cheeks.

‘Huiying, you are so beautiful!’

Huiying suddenly felt a little shy, said to herself, glanced at Li Xin, and then handed it to Zhang Nai: "I'll give it to you!"

"ah?"

Zhang Nai took it, followed him, looking left and right, but he couldn't see enough.

Huiying couldn't help but frown slightly. What's going on with Zhang Nai? He was heartless, right? So he coughed twice.
