Unparalleled Women in the World

The golden crow moved westward, and it was already sunset.

Anping Mansion, Honghui Courtyard.

Chi Yanfei sat on the gooseneck railing under the porch, dazed.Suddenly there were gentle footsteps in front of the long corridor, she raised her head slightly, and saw Mei Wangqing wearing a black embroidered double phoenix royal royal gown, with an elegant and vulgar face covered with a yellow Yu Hui, as if coming from a wonderful place, was walking towards her with lotus steps.

A dark color flashed across Chi Yanfei's beautiful eyes:

"The court is early at Chenshi, and the court has already retreated before Sishi today. Wangqing, you have stayed in the palace for an hour."

Mei Wangqing's phoenix eyes slightly dimmed, she stepped closer to Chi Yanfei, and sat beside her:

"Ji Huan stayed with me for a while to discuss something."

Chi Yanfei's Qingmeiwushuang face was suddenly as cold as ice, and her voice was cold and thin:

"Need to discuss something? It's clearly a sincere confession, and I'm afraid I'm begging for mercy in the future, right?"

Mei Wangqing panicked for a while, this feeling made her feel a little helpless, her voice was weak:

"Yan Fei, don't think too much!"

Chi Yanfei stretched out her slender jade-like hand, caressed Mei Wangqing's brows and eyes, and then touched her beautifully curved red lips, touching her fingertips lightly, lingering for a long time:

"You don't know what she is thinking, as a woman, I know it"

"I am a woman too"

"No, Wangqing is a girl..."

She could hear the unfinished words in it, and in Chi Yanfei's eyes, she only thought of her as a weakling!

Mei Wangqing felt ashamed and felt underestimated again, she replied angrily:

"From now on, you are not allowed to be on..."

"It's okay to do it occasionally, it adds to the interest..." Chi Yanfei's eyes were fascinated, and she said meaningfully:

"It's just that Wang Qing wants to tame me, sister, that's not okay! It's better for you to lie down as a female!"

The west wind was blowing, and yellow leaves were already scattered in front of the promenade.

Mei Wangqing took Chi Yanfei's hand and held it gently:

"Yan Fei, Ji Huan's birthday is coming soon."

Chi Yanfei returned to shake her hand, and said in a calm voice:

"Let the steward of the mansion pick a precious jade ornament from the warehouse and present it."

"I promised, this gift must be unique in the world!"

Mei Wangqing's voice was very soft, and Chi Yanfei could hear a bit of comfort from it, but her heart was slightly chilled, and a ferocious smile appeared on her face:

"Are you responding to her? Or flattering her?"

"She is the empress, so this gift is naturally expensive. I am a subject, so I am... trying to please her! Yan Fei, don't be angry, what do you want?"

Well, I will get it for you, if there is no one in this world, I will try to make it. "

"What do I want, will you get it for me? If it is her life?"

Mei Wangqing's body froze instantly, her phoenix eyes were full of complexities, she was speechless.

"If you soften up a little bit, she will be encouraged, and she will try her best to take another hundred steps towards your heart..." Chi Yanfei's chest was stuffy and angry, and her voice was depressed and angry:

"When I think of you being occupied and desecrated by her, I wish I could kill her..."

The two women, Ji Huan and Chi Yanfei, looked at each other with disgust, and couldn't tolerate each other!

Mei Wangqing lamented: With Ji Huan, she can win Chi Yanfei's safety, but with Chi Yanfei, her anger and revenge will only bring about a loss for both sides!

Mei Wangqing leaned over and sat on Chi Yanfei's lap, put her arms around her neck, and buried her face deeply in her arms:

"Yan Fei, you know my heart."

"Now it's safe and sound, and we're both safe. Don't be impulsive. I don't want anything to happen to you."

Chi Yanfei squinted her eyes slightly, feeling the warmth and softness in her arms, she reached out to caress Mei Wangqing's back:

"Being supported by you and hiding under your wings, am I useless?"

"We are equal, and we should support each other. What are you accepting and hiding? These two words are inappropriate! Yan Fei is beautiful, has both civil and military skills, and knows everything about astronomy and geography. Such a perfect person, he still treats someone like me Sincerely, I have you, I can wake up from my dreams with laughter, how can I think you are useless?"

Chi Yanfei felt relieved, she lowered her head, and put her black hair on her cheek: "Wang Qing."

……

Astronomy Bureau.

As soon as Mei Wangqing stepped into the smelting gate, she felt a burst of heat rushing towards her, and her face was already sweating.

The prisoner at the Smelting Gate saw Mei Wangqing, and was suddenly surprised, she hurried forward and saluted: "My lord."

Mei Wangqing walked in slowly, and saw that the blacksmiths were only wearing a thin layer of single clothes, their shoulders and backs were soaked with sweat, and some of them simply rolled up their robes, revealing their wheat-colored arms.They had an orderly division of labor and strict discipline. Mei Wangqing and Jian Zheng stood by and watched everyone work, but no one made a conclusion.Some of them took out the red billet from the furnace; some were pouring coolant to cool down the metal utensils; others were constantly forging the billet to shape it.

Mei Wangqing cut to the chase: "I want you to refine something."

The supervisor's eyes lit up: "Is it a divine weapon?"

"No." Mei Wangqing laughed, she said slowly, "It's glass."

Most of the mirrors here are made by polishing the copper surface, and the facial features can be seen, but they are a bit blurry. Mei Wangqing decided to make glass mirrors. To make glass mirrors, the first thing to use is glass.

This glass is usually sand liquid formed by heating sand, quartz stone, etc. at high temperature for several hours, and then the liquid is shaped and cooled to become glass.

The materials needed are mainly sand, and the tools are crucibles and furnaces, both of which are available in smelting doors.

Everything must go through failure before it can succeed. Mei Wangqing originally thought that after the sand is heated and cooled in a furnace, transparent glass can be obtained.

Unexpectedly, I got a piece of slightly impurity, slightly blackened, semi-transparent glass.She thought about it, these impurities should be removed, these blackened substances are probably metals, she ordered the craftsmen to wash the sand several times first, pick out impurities, iron ore, etc., and then put it into the furnace.

Sure enough, the glass obtained after this was indeed very transparent, but it was easily broken. Mei Wangqing watched the blacksmiths fail over and over again, and she tried many times, but found that the annealing process was not done well.

"Is there any stone with better thermal insulation performance?"

A blacksmith said: "There is a kind of vermiculite."

This vermiculite can expand dozens of times after heating, and it can keep heat and insulate, and the effect is very good.After the glass is slowly delayed and cooled, it is not easy to break.

The glass is transparent and unbreakable, which is excellent. If there is only one transparent color, it would be too monotonous. Mei Wangqing added a little sodium carbonate, calcium nitrate, gypsum, etc. to the sand to mix, and she found that some of the glass was glowing. Greenness means that a little iron has been added to the sand; some gloomy colors like blue sky are due to the addition of lead.The blacksmiths also found the fun, trying to add other substances, such as the mud on the wall, and even the bottom ash of the boiler, which turned out a charming purple color.

Mei Wangqing asked the blacksmith to create a hollow and straight metal blower, one end of which was covered with a layer of melted sand, and the craftsmen turned the metal blower from time to time, then poured water to cool it, and blown the glass rod with air... until the shape was roughly After forming a rudimentary shape, it was then put into the furnace and burned. The shape of the glass is constantly changing, gradually growing, gradually becoming larger and gradually flattening, with a slender head and neck, and a distended midsection.

When the first finished product of azure glass bottles with narrow neck and wide mouth was lined up in front of the main hall of the smelting gate, all the craftsmen under the gate showed enthusiasm. It was so beautiful and exquisite!

Mei Wangqing smiled and said: "Use your imagination and refine your craftsmanship of firing, forging, and glass blowing. Whether it's bottles, jars, incense burners, inkstones, flower and animal ornaments, the more complicated and exquisite the better, this thing, Take the high-end route!"

Mei Wangqing tried to make a glass mirror later, but she failed many times.

Didn't it mean that as long as one side of the glass is plated with aluminum or silver?

The answer is: no!

Aluminum and silver cannot be directly bonded to glass. Mei Wangqing asked craftsmen to coat glass with melted silver, but found that it was still not possible.

Inspired by Mei Wangqing, the craftsmen suggested that all hardware be used for paste plating. The gold, silver, copper, iron, and tin have all been tried, but they still fail. If they are mixed, paste tin foil, and then plated to dissolve Mei Wangqing found that the silver and tin still reacted, and the mirror could illuminate people, but it was still far from the brightness and clarity of glass in her memory.

There must be a step missing.

Mei Wangqing thought about it every day and dreamed at night. Instead, she dreamed of a mirror news about glass production that she saw in modern times. In this flash of inspiration, she remembered three things, silver nitrate, ammonium water , stannous chloride.

Mei Wangqing knows that ammonia is a powerful complexing agent that can complex with various metal salts; stannous chloride can be used as an intermediary for silver nitrate for silver nitrate plating to make the brightness better after plating.

These three things are not available here, and Mei Wangqing had to recall her chemistry knowledge.

Silver nitrate needs nitric acid to react with silver, unfortunately there is no nitric acid here, but hydrochloric acid and sodium nitrate can react to produce nitric acid, unfortunately there is no hydrochloric acid here; to produce hydrochloric acid, oxalic acid and calcium oxide (quicklime) are needed, and there is no oxalic acid here, but Oxalic acid can be obtained from vegetable

Calcium oxalate is extracted from vegetables, and then reacted with hydrochloric acid to extract oxalic acid. Again, there is no hydrochloric acid here.

Mei Wangqing frowned, and she thought: Maybe acetic acid can be used instead of hydrochloric acid to react with calcium oxalate, which may be very slow; there is another method that is easier to extract oxalic acid, which requires starch or sugar to react with nitric acid. There is nitric acid.

In the laboratory of Honghui Institute, Mei Wangqing tried to use acetic acid instead of hydrochloric acid to react with calcium oxalate, or react with starch and sugar, but failed twice, but got a pot of dilute oxalic acid, which she repeatedly purified. Finally got a bowl of solidified slightly yellow oxalic acid.With oxalic acid, she later experimented with hydrochloric acid and nitric acid in large quantities.

Mei Wangqing stretched her waist, she showed a faint smile, picked up two pieces of broken silver on the table, and put them into the nitric acid water, only to see that the water had a deep blue color, which meant there was copper in the silver, she sighed. Sigh: Silver is more expensive than copper. It seems that the silver casting supervisor and money casting workshop under this young mansion are suspected of being dirty!

As for ammonia: it needs to react with ammonium chloride and sodium hydroxide.Ammonium chloride: It is the ammonium salt of hydrochloric acid, and sodium hydroxide is caustic soda. Although there is no caustic soda, it can be extracted by mixing soda ash in the store with calcium hydroxide to form a solution. What is calcium hydroxide? It is slaked lime. Take a casual walk on the outside road, scrape the corner of the wall behind the house, and you can get slaked lime.

And stannous chloride: take tin to react with concentrated hydrochloric acid to obtain stannous chloride.

First, wash the glass, then apply a layer of stannous chloride solution, then silver nitrate solution, then mix evenly with ammonia water, pour it on the back of the glass plate, and finally, coat it with a layer of copper, which took a lot of effort. After a while, Mei Wangqing finally made a mirror.

After that, she thought about some light means of transportation, such as bicycles. This is not difficult to make, and it is also easy to promote in Beijing. The key is that it is not as light and cheap as Ma Zhandao.

The first bicycle produced here was given to Chi Yanfei. Mei Wangqing specially wore a solid suit, with the hem tucked into her belt, and she lightly stepped onto the stool. She held the front of the bicycle with both hands, Stepping on and kicking, the wheels turned straight, and they were already heading towards the court. The speed was still very fast, and they were about to hit the green pine tree.

Jiufang stared wide-eyed: "Master..."

Chi Yanfei said anxiously: "Wangqing, be careful."

Siwen has no expression on his face: the master has slipped away!

As soon as the startled sound came to an end, Mei Wangqing turned the front of the car leisurely, and she had already passed the tree with ease. She was riding on the car, walking along the path in front of the courtyard at a fast and slow pace, occasionally falling into the tree. Bend between trees, or turn into flowers and trees, and slowly drill out of them.

Chi Yanfei took the front of the car from Mei Wangqing, she shook her head and rejected Mei Wangqing's request to help her with the back seat of the car.

"Wangqing, don't underestimate me!"

"I'm worried, you're going to fall!"

Chi Yanfei glanced at her beautifully, and hummed softly, "What about our bet?"

"What are you gambling?"

"If I don't fall down, I will learn it. You have to listen to me these two days; otherwise, I will listen to you!"

Mei Wangqing thought for a while, then nodded: "Okay!"

Chi Yanfei is very competitive, the key is that she is very smart, plus she has a slender body and flexible hands and feet. She can learn it with just a stick of incense when she rides a bicycle.

These two days, for Yu Chi Yanfei, it was the time to taste the fruits of victory, and for Yu Mei Wangqing, it was a painful and joyful experience.

In a blink of an eye, October [-]th, the Longevity Festival is here.

In the palace, Chunhua Hall held a grand banquet. This was Empress Xiqing's first birthday banquet after she ascended the throne.
