Chapter 548 Mirrors are good, but people are not, so it's okay!
The next day.
early morning.
Jinling City, East Palace.
Heavy snow fell from the sky, covering the East Palace with a layer of silver.
As the new year is approaching, all three provinces and six ministries are busy.
In the past two years, the Wei Dynasty has successively completed political, military and agricultural reforms, with remarkable results.
Emperor Wei was waiting for the three provinces and six ministries to submit a satisfactory answer to him.
However, whether the reform is successful or not cannot be fully reflected in the year-end data.
The living conditions of the people of the Wei Dynasty today are enough to explain everything.
Although the reform has only been completed for a year, people still have surplus grain in their granaries after paying agricultural taxes.
This is enough to illustrate the success of the reform.
Among the six ministries in the three provinces, the Ministry of Household Affairs is the busiest, especially since the fiscal revenue of various regions has soared this year.
The granaries in every state and county in the Wei Dynasty were expanded.
This is the advantage of not having middlemen to make profit from the price difference, which makes the people rich and the court even richer.
Moreover, due to the promulgation of the tax system of "sharing a small share of a person's share with an acre", the population of the Wei Dynasty became mobile.
Landowners have also turned their attention from land acquisition to investment business.
This led to great progress in the commercial development of Wei Dynasty.
Officials in the three provinces and six ministries were busy.
Qin Yu was not idle either and was helping Zhang Zhixin solve the problem.
He wanted to produce glass mirrors and launch a commercial counterattack against Dayi bronze mirrors.
From now on, in terms of commerce, only the Wei Dynasty can attack Dayi, and there is no possibility for Dayi to attack the Wei Dynasty.
After breakfast in the East Palace early in the morning.
Deng Bao prepared the things for making glass mirrors for Qin Yu.
Since the weather was quite cold, Qin Yu started working in a room next to the side hall.
Xiao Nan still did not lead the training of the Three Thousand Battalion today, but accompanied Qin Yu.
Looking at the simple materials and a piece of glass on the table.
Xiao Nan frowned and asked doubtfully: "Brother-in-law, do you only need this little thing to make a glass mirror?"
Qin Yu raised his eyebrows, "What else? Just have glass. Glass is the main material."
Then, under the gazes of Xiao Nan and Shen Binglan.
Qin Yu started making it. In fact, making a glass mirror is very simple.
The glass is already there, all that needs to be made is the coating behind the glass.
The coating is not troublesome, it is just a chemical called tin amalgam.
Qin Yu first applied a layer of tin on the glass surface, and then applied a layer of mercury.
Since then it has become tin amalgam
Finally, apply a layer of vegetable paint on the back of the mirror, and the glass mirror is completed.
The whole process took about as long as one stick of incense.
Xiao Nan and Shen Binglan were still watching seriously.
Qin Yu had already set up the glass mirror and said with a smile: "Let me show you what a real mirror is."
As he spoke, he pointed to the glass mirror and looked at Xiao Nan and Shen Binglan with raised eyebrows.
“Holy shit!!!”
Xiao Nan looked at the glass mirror, his whole body was numb, he touched his head and face, full of shock, "This! This! This...is this fucking me!?"
Xiao Nan felt that this was the first time he could see his appearance so clearly, down to the hair.
Not to mention Xiao Nan was shocked.
Even Shen Binglan, who had always remained calm when Mount Tai collapsed, showed a surprised expression.
She had never seen a mirror with such high definition, which reflected a person's appearance completely and clearly.
Shen Binglan also couldn't figure out how it was just a piece of glass that could suddenly illuminate people so clearly.
Looking at the shocked looks of the two of them.
Qin Yu smiled and said, "Let me tell you, the clarity of the bronze mirrors made in Dayi is not as clear as mine. Have you ever seen such a clear mirror?"
Xiao Nan walked over in amazement, "Brother-in-law, let alone meeting me, I have never thought that if I hadn't seen you make this with my own eyes, I would have thought you were a treasure borrowed from heaven."
"Tsk..."
Qin Yu glared at Xiao Nan, "How many times have I told you, science! We must believe in science! Don't always think about gods and ghosts. We must be atheists and control our own destiny.
In hand!"
"hehe......"
Xiao Nan smiled, nodded quickly and said, "Brother-in-law is right!"
Qin Yu turned to look at Shen Binglan again and asked, "Miss Shen, how is my glass mirror?"
Shen Binglan raised her eyebrows slightly, "It's okay."
Qin Yu raised his eyebrows and said in a high tone, "Are you okay?"
Shen Binglan said indifferently: "The mirror is good, but the person is not, so it's okay."
The words fell into place.
Xiao Nan couldn't help laughing, "Hahaha..."
The only person in this world who dares to criticize Qin Yu like this is probably Shen Binglan.
"cut!"
Qin Yu waved his hand disdainfully, "I am loved by everyone, and the beautiful Qin in the workshop has a very noble moral character!"
Shen Binglan glanced at him contemptuously.
In her heart, Qin Yu will always be a prodigal.
Xiao Nan looked at Qin Yu and asked doubtfully: "Brother-in-law, what's the principle behind this? Glass is obviously transparent, but if you apply a layer of something on it, why does it turn into a mirror?"
Qin Yu looked serious and said seriously: "This involves knowledge of physics."
Xiao Nan was full of doubts, "Physics?"
Qin Yu nodded, "This is called the principle of reflection. The ability of a mirror to reflect light is determined by the incident angle of the light, the smoothness of the mirror surface and the coating film behind the mirror."
"Is the smoothness of a copper mirror comparable to that of our glass? The coating film behind us is tin amalgam, the best material for making glass mirrors, so the reflected scenery is very clear."
Xiao Nan listened and suddenly realized, "Oh~ So that's it."
Qin Yu looked at Xiao Nan in surprise, "Do you understand?"
Xiao Nan shook his head, "I don't understand."
Qin Yu: "..."
Shen Binglan was also listening, but she was also confused.
She had never heard of such messy things as physics, emission, light, etc.
Shen Binglan felt that these things either came from the sky or from another world.
Qin Yu waved his hand, "Forget it, forget it, the things involved here are too profound. You just need to know that glass mirrors are better than bronze mirrors."
Xiao Nan nodded repeatedly, "Brother-in-law is right!"
He originally thought it was a big project, but he didn't expect it to be so simple.
Qin Yu only used a stick of incense to create a glass mirror with such high clarity. If Dayi knew about it, he would be furious to death.
It’s really worth comparing people with others, and throwing things away when comparing goods.
There was a pause.
Xiao Nan looked at Qin Yu and continued: "Brother-in-law, those pigs are ready for slaughter. How about we kill one and have a small banquet to celebrate?"
