When I just got divorced, I was overheard

Chapter 459 Making an Astronomical Mirror

Today is the fourteenth day. Although the moon is not the largest and roundest, it is still close.Unexpectedly, Nong Yue actually likes the stars instead of the moon.

"Okay, I'll watch the stars with you at night, but what's the point of watching the stars?"

"Other people often look at the moon at night, but those who notice the stars are mostly Taoists."

The smile on Nonyue's face became sweeter when she heard Li Xiuzhu's promise, but she said: "The first time I fell in love with the starry sky was when I saw the Milky Way in the summer when I was a child."

"That kind of beauty is something that even the moon cannot bring me. Later I fell in love with the starry sky."

"Even if I can't see the Milky Way from autumn to spring, I still like the starry sky."

"For this reason, I also learned about the stars in the sky."

"Three walls, four elephants and 28 constellations."

"This seemingly chaotic starry sky has its own unique order, which is so fascinating."

"It's a pity that I've been watching them for so long, but I don't know anything else except that they have a fixed order."

"A few days ago, sister Xiaomeng and I learned about the Taoist celestial star-gazing technique, but we have only just gotten started."

Li Xiuzhu smiled when he heard this and said, "To be honest, the stars that I understand and the stars that Taoists understand are completely two different things."

"Ah?" Nongyue was a little numb. She didn't expect that Li Xiuzhu would say such explosive words as soon as he opened his mouth, but she was more curious about the answer.

"Li Lang, what do you know about the stars?"

After Nongyue finished speaking, Li Xiuzhu noticed someone before he could speak.

Li Xiuzhu turned around and immediately saw Xiaomeng.

At this time, Xiaomeng looked at the two of them with a cold face, with no sadness or joy on their faces, as if they were just strangers passing by.

But Li Xiuzhu knew that Xiaomeng had just come here using Qinggong, so it was most likely that he appeared after hearing Li Xiuzhu say that the stars he understood were different from those of Taoism.

"Well, you have to listen too, come here."

Nong Yue was startled, then subconsciously looked back and was startled again.

"Sister Xiaomeng, why are you here? When did you come?"

Xiaomeng's feet flashed, an afterimage passed by, and the person appeared in front of the two of them.

Regarding Nong Yue's words, she did not refuse to answer, nor was she embarrassed to disturb the two of them. Instead, she said calmly and honestly: "I just came here, when I heard my husband say that the stars he understands are different from Taoism."

"Well……"

Without waiting for Nongyue to say anything, Xiaomeng looked at Li Xiuzhu and continued: "What do you know about the stars?"

Li Xiuzhu smiled and asked, "What do you think stars are?"

The two of them were startled at the same time, not understanding what Li Xiuzhu meant.

But at the same time, he fell into thinking.

"Aren't stars just stars? What else could they be?"

Unlike Nong Yue's voice, Xiaomeng's thoughts are simple and his voice will not appear at all. Instead, he answered: "Is it a meteorite? Or is it meteorite?"

This is the conclusion Xiaomeng drew based on the stars falling from the sky recorded in ancient books.

Li Xiuzhu said the answer directly without nodding or shaking his head.

"Whether it is meteorites or meteorite iron, they are actually mostly the same as what we can produce in the Great Zhou Dynasty. There are only a few things that the Great Zhou Dynasty does not have."

"The reason why heavy meteorites or iron meteorites are formed is that you can imagine them as a mountain of unsmelted iron ore."

"It is condensed and compressed under the pressure and high temperature generated by the combustion during landing, just like forged steel that has been tempered by a top craftsman." Li Xiuzhu had tried to simplify his words as much as possible, but they were still a little confused and confused.

Xiaomeng frowned and asked: "Husband, what do you mean the stars are big weeks?"

Li Xiuzhu shook his head, thought for a while, considered his words, and then said, "That's not quite accurate. The stars are stone balls, huge stone balls."

When Nong Yue heard this, her brows furrowed and she asked, "It's impossible. Stars can shine. How can it shine if it's a stone ball?"

It’s over, Little Sunflower Class has started, I’m afraid I won’t be able to explain it in a short time.

And because of the astronomical mirror.I'm afraid it will be difficult to convince them.

Fortunately, he had made many glass mirrors during the march and war. Although the specifications were not suitable, as long as they were melted and reshaped and polished with suitable molds, suitable astronomical mirror lenses could be produced.

Li Xiuzhu thought for a while and said, "It may be a bit hollow for me to say this. I will make something and watch the stars with you at night."

"By the way, everyone is called. I don't want to have to talk about it again."

Nong Yue nodded when she heard this. Although she was no longer watching the stars alone at night, knowing the secrets of the stars was extremely attractive to her.

Xiaomeng asked, "Can I stay and help you?"

Li Xiuzhu shook his head at first, but then nodded again.

Because in addition to making the lens, the lens barrel also needs to be made. If the flames want to melt these things, it is best to have a master to pull the fan.

"follow me."

The two of them appeared in Li Xiuzhu's small production workshop one after the other.

In fact, it is a converted woodshed, with many tools inside, including stoves, crucibles and blasters.

The reason why a woodshed is used is because it is surrounded by mud brick walls except for the door, so there is no fear of fire.

Li Xiuzhu mixed the soda ash and glass evenly and poured it into the crucible he had made before. He then said to Xiaomeng: "If you want to melt the glass in a short time, you need a higher temperature, so you have to melt it as quickly as possible later." Blow the air to raise the temperature inside it.”

"Of course, you don't have to go too fast. Just keep it at a constant speed."

Li Xiuzhu didn't waste any space either. In addition to melting glass, he also melted copper.

These coppers are used to make the barrel of the astronomical mirror. As long as it is thin enough, it is not too heavy. However, a thick and heavy frame is required, which is not very flexible.

Xiaomeng didn't expect to be asked to light a fire, but she didn't have any burden. After hearing this, she squatted down and sat on the small stool next to the blast.

Li Xiuzhu was not idle either, looking at the wordless book to adjust the concave and convex molds of the lenses.

But it can only be adjusted for one second. The current process does not allow it. This is the most that can be done. He will need to polish it carefully later.

Fortunately, you have the internal force at hand and learn about the manual grinding wheel.

The props he will use in the evening explanation include candles and bronze mirrors, and the quantities are not small.

After the softened and fused glass was poured into the mold, Li Xiuzhu asked Xiaomeng to collect bronze mirror candles.

Ten bronze mirrors and candles should be enough. This is not difficult. Women at home have enough mirrors.

Copper juice is also available. Compared with the lens, the lens barrel is much simpler. You only need to lay a thin layer of juice and let the barrel shape after it cools.

Li Xiuzhu spent the whole afternoon in the small workshop, and it wasn't until dinner that he finished it.

It's definitely not possible to be too precise, but he tried and could see most of the planets in space.

It's mainly just an explanation, there's no need to be so persistent.
