After seeing the pigs with his own eyes, Qi Lele inexplicably felt that those piglets were a little pitiful, and suddenly remembered that there was still a road to chemical castration.

Chemical castration is simple, as long as a mixture of sodium chloride and formaldehyde solution is injected into the testicles and pellets of the boar cubs who have just been born for a few days.

But the difficulty lies in this formaldehyde solution and the syringe used to inject the mixture into the testicles and balls.

In the past, Qi Lele would not think about this at all, but now, after seeing the skillful hands of Jing Yan and Jing Yue with her own eyes, she inexplicably felt that they might be able to toss the syringe out.

If a syringe could be developed, it would be an epoch-making event in medicine, right?

As for the formaldehyde solution, Qi Lele vaguely remembers that it can be extracted from methanol, which can be obtained by wood distillation, but this involves a lot of chemical knowledge and professional experimental equipment.

Thinking of this, Qi Lele asked Xie Zi'an, "Have you ever seen colorless and transparent glass?"

"Colorless and transparent?"

"Yes, it's completely transparent without the slightest color."

Xie Zi'an muttered, "I've seen a lot of colored glass, but I've never seen anything completely colorless and transparent."

Qi Lele was not disappointed, she remembered reading articles before, glass technology in the East and West have their own development.

Because of the different raw materials, the final development direction is also very different.

The West is lime and sodium glass, so it is relatively transparent.

The East is called glaze, in fact, it belongs to lead barium glass, because of its colored attributes, and the performance can not compete with ceramics, so it is more made into beautiful handicrafts.

According to Qi Lele's knowledge, there is a kind of boron glass in modern high-grade glass, which is to add borax to the raw material of lead barium glass, so as to make a glass with good corrosion resistance and high thermal stability.

If this boron glass can be made, many problems can be solved.

But this kind of thing needs to be done by professional people.

Seeing that Qi Lele was completely immersed in her thoughts, Xie Zi'an did not interrupt silently, and she was almost sure that she had some new idea in her heart.

Sure enough, when Qi Lele came back to his senses, he said bluntly, "I have an idea! But I don't know if it's worth it."

Xie Zi'an said, "Why don't you think it's worth it?"

"Because the idea burns money." Qi Lele looked at him and said in a serious tone: "The point is, there is a high probability that so much silver has been burned in vain, and the bamboo basket will be empty."

No wonder it's so bothered!

Xie Zi'an asked, "What kind of high-end talents does Madame need this time?" Fired glass?"

Qi Lele's eyes widened: "You won't tell me that there are even such talents in the family, right?"

Xie Zi'an smiled: "Not really, but if you look for it sincerely, you can find people."

Qi Lele sighed: "Forget it, let's talk about it later."

The steps should not be too big, and it is easy to pull on that.

Step by step and down-to-earth is king.

Having said that, after meeting Jing Yan and Jing Yue, Qi Lele still mentioned the matter of injection needles.

"It's as slender as a silver needle for acupuncture, but it's hollow in the middle?"

Qi Lele nodded, "Yes."

"How big does this hollow need to be?"

"It doesn't have to be too big, as long as you can make sure the water can pass through."

Jing Yan instantly understood: "Then the hollow in the middle cannot be broken, and it can be done from beginning to end."

"Exactly!"

Qi Lele thought about it and simply explained the principle of the syringe in detail.

The two of them listened to their eyes and subconsciously asked, "What does the young lady want to do with this syringe?"

"It's very useful, it can be used to kill pigs, and it can also heal people."

Tse Tsz-on: "......"

Su Zhengtao, Su Yi: "......"

Jing Yan and Jing Yue were thinking about that

The principle of injection, I don't even think there is anything wrong with putting pig snatching and treating people together.

Seeing the two of them muttering together as if no one was around, Qi Lele couldn't help but look at Xie Zi'an.

Xie Zi'an said, "Let's go back."

"There's really no rush to this! Even if I can't figure it out, it doesn't matter, I just suddenly remembered it coldly, and I mentioned it in passing."

Xie Zi'an smiled: "They can't listen to these words right now, it's not early, let's go first."

Qi Lele nodded.

When he returned to the courtyard, Su Zhengtao disappeared in the blink of an eye.

It seemed that he was shocked by the fact that his young lady wanted to make a hollow needle and prick it into the pig's lower three roads, Su Zhengtao planned to ask Geng Dafeng what scene they had shown the young lady in the four afternoons before she had such a terrible idea!

At night, Xie Zi'an played with Qi Lele's long hair and asked casually, "Madame knows how to fire colorless and transparent glass?"

Qi Lele also confessed: "I only know the general direction, and I don't know exactly how to operate."

"Want to make syringes out of colorless and transparent glass?"

"Yes! It can also be used as a syringe for a syringe!"

Xie Zi'an couldn't help but smile: "What did Madam originally plan to use it for?"

Qi Lele thought for a while and said truthfully: "Originally, I planned to make a set of utensils for chemical experiments to refine formaldehyde solution that can castrate pigs."

Tse Tsz-on: "......"

Qi Lele raised his face: "Just to rip pigs, I went to such great lengths, isn't it stupid?"

Xie Zi'an flicked her forehead: "Don't be stupid, things have to be made first before you know what they can do."

This made Qi Lele's heart warm: "Actually, there are a lot of things that can be refined by that experimental vessel!"

"Then find someone to make it."

Qi Lele: "......"

"Xianggong, you can't always indulge me like this!"

Xie Zi'an lowered his eyes and saw Qi Lele's shadow imprinted in his eyes close at hand, and said, "I don't indulge you, who is indulgence?"

Qi Lele's heart softened into a pool of spring water, the kind of hot spring water that kept bubbling small bubbles.

I don't know who took the initiative first, but I saw the two getting closer and closer, and finally stuck in one place, without even noticing that the candle was extinguished.

After a long time, Qi Lele's delicate voice with a little wheezing came from the darkness: "Actually, if we can really make boron glass, we will make a fortune!"

Xie Zi'an chuckled in her ear: "Madame can still think about other things, it seems that she has not done enough for her husband. Huh?"

It is impossible to say that the nephrite jade is warm and fragrant, the ears and temples are grinding, the reins are beautiful, and the flowers are rippling.
