Today is the fourteenth, and although it is not the time when the moon is at its maximum and round, it is not much different. I didn't expect the moon to like the stars, not the moon.

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

"Others often look at the moon overnight, and most of the people who notice the stars are Taoists."

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

"That kind of beauty can't even be brought to me by the moon, and then I fell in love with the starry sky."

"Even if I can't see the Milky Way in autumn and spring, I still love the starry sky."

"For this reason, I also learned about this starry sky."

"Three walls, four elephants, and twenty-eight constellations."

"It's fascinating that this seemingly chaotic starry sky has its own unique order."

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

"A few days ago, Sister Xiaomeng and I learned about the Taoist Heavenly Star Qi Technique, but we were just getting started."

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

"Huh?" Langyue was a little numb, but she didn't expect Li Xiuzhu to be so explosive as soon as she opened her mouth, but she was more curious about the answer.

"Li Lang, what kind of stars do you know?"

When the words fell, Li Xiuzhu noticed a person before he could speak.

Li Xiuzhu turned his head and immediately saw Xiaomeng.

At this time, Xiaomeng looked at the two of them with a cold face, there was no sadness or joy on his face, it seemed that he was just a stranger passing by.

But Li Xiuzhu knew that Xiaomeng had just come here with light skills, so the biggest possibility was that he heard Li Xiuzhu say that the stars he understood were different from Taoism, so he appeared.

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

Langyue was stunned, and subconsciously looked back and was stunned.

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

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

She didn't not answer Lang Yue's words, nor did she bother the embarrassment of the two, but said honestly with a calm face: "I just came, from when I heard my husband say that the stars he understands are different from Taoism. ”

"Hmm......"

Without waiting for Lang Yue to say anything, Xiaomeng looked at Li Xiuzhu and continued: "What kind of stars does Husband know? ”

Li Xiuzhu smiled when he heard this, "What do you think the stars are?" ”

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

But at the same time, I fell into thought.

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

Unlike the appearance of Lang Yue's heart, Xiaomeng's mind was simple, and he basically did not appear in his heart, but replied: "Is it a meteorite?" Or is it meteoric iron? ”

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

Li Xiuzhu didn't nod or shake his head, and directly said the answer.

"Whether it's a meteorite or a meteorite, in fact, most of the things that can be produced by our Great Zhou are the same, and only a few things are not available in Great Zhou."

"And the reason why heavy meteorites or meteorites are formed, you can think of it as an unsmelted mountain of iron ore."

"The pressure generated by the combustion and the high temperature at the time of landing converge and compress like the forged steel after a top craftsman has been tempered for thousands of years."

Li Xiuzhu had tried his best to streamline his words, but they were still a little confused.

Xiaomeng frowned and asked, "What does Husband mean that the stars are a big week?" ”

Li Xiuzhu shook his head, thought about it, and said after considering the words: "It's not accurate to say this, the stars are stone balls, huge stone balls. ”

Hearing this, Lang Yue frowned and asked, "Impossible, the stars will shine, if it is a stone ball, how can it shine?" ”

It's over, the little sunflower class has started, I'm afraid I won't be able to understand it in a short time.

And because of the astronomical mirror. It's hard to convince them.

Fortunately, because of the march and war before, he made a lot of glass mirrors, although the specifications are not suitable, but as long as they are melted, they can be reshaped and polished with a suitable mold to produce a suitable astronomical mirror lens.

Li Xiuzhu thought for a while and said, "It may be a bit empty for me to say this, I'll go do something and watch the stars with you at night." ”

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

Hearing this, Lang Yue nodded, although she didn't accompany her to watch the stars alone at night, but knowing the secrets of the stars seemed extremely attractive to her.

Xiao Meng asked, "Can I stay and help you?" ”

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

Because in addition to the production of lenses, the lens barrel also has to be made, and if the flame wants to melt these things, it is best to have a master to pull the fan.

"Follow me."

The two of them quickly appeared in Li Xiuzhu's small workshop.

In fact, it is a firewood house, and there are many tools in it, including a furnace, a crucible and a blast.

The reason why the firewood house is used is because there are mud brick walls all around except for the door, so it is not afraid of fire.

Li Xiuzhu stirred the baking soda powder and glass evenly, then poured it into the crucible that he had made before, and then said to Xiaomeng: "If you want to melt the glass for a short time, the temperature needs to be high, so wait for you to pull the air as quickly as possible to let the temperature inside it rise." ”

"Of course, it doesn't have to be too fast, just keep it at a constant speed of a big fire."

Li Xiuzhu didn't waste space, in addition to melting glass, there was also copper.

These coppers are used to make the barrel of astronomical mirrors, as long as they are thin enough, they are not too heavy, but they have to use thick and focused shelves, which are not very flexible.

Xiaomeng didn't expect to be pulled to make a fire, but she didn't have any burden, so she squatted down and sat on a small stool next to the blast.

Li Xiuzhu was not idle, looking at the wordless book to adjust the concave and convex mold of the lens.

But it can only be adjusted for one second, the current process does not allow it, and this step can be done at most, and he needs to polish and polish it in the future.

Fortunately, the internal force is in hand, and the manual grinding wheel understands it.

And the props he used to explain at night are candles and bronze mirrors, and the number is not small.

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

Ten bronze mirrors and candles should be enough, this is not a difficult thing, the women in the family have enough mirrors.

Copper juice is also available, compared with lenses, the lens barrel is much simpler, as long as a thin layer of juice is laid, and the roll is set after cooling.

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

No matter how fine he was, he couldn't do it, but he tried it, and he could see most of the planets in space.

The main thing is to explain, there is no need to be so persistent.
