Unexpectedly, Liu Yunde and Xiao Taohong actually started to live like this.

After Li Laohan learned about it, he stomped his feet and scolded, "Stinky and shameless, no blood." ”

Li Xiaoyue chuckled when she saw this, "If Liu Yunde had blood, he would have died eight times ago." As the saying goes, good people don't pay for their lives, and bad people leave a thousand years, maybe that's what it means. ”

Li Laohan sneered, "I just can't be angry, this dog thing actually survived, and I tried to kill him several times, but I couldn't." ”

Li Xiaoyue comforted, "Fortunately, she has been arrested now, and she is trapped in the yard and can't go anywhere." ”

"I heard Gongsun say that he wants to go with his eldest brother to catch the spies, and don't let Mr. Gongsun go, okay?"

When Li Laohan heard this, his eyes were complicated, his daughter was outgoing, was it Li Xiaoyue?

Knowing the danger outside, don't let your fiancé go out, and be willing to let your eldest brother go out?

Seeing the complicated eyes of the old father, Li Xiaoyue couldn't cry or laugh, "Dad, don't think about it. It's not that I'm reluctant to Gongsun Lian, but I think that the purpose of those people this time may be gunpowder. ”

"Mr. Gongsun is not here, although it is handed over to Niu Dazhuang and is trustworthy, his ability may not be able to complete the task."

Hearing his daughter's words, Li Laohan's heart felt a little more comfortable, "Xiaoyue, no matter how good a man is, remember, he can't compare to his father and brother." ”

Li Xiaoyue nodded again and again, and said with a smile: "That's natural, even if Mr. Gongsun has a good character, but I also think that my father is good, and my eldest brother is good." ”

"That's pretty much it." Li Laohan smiled, and then he had the heart to explain to his daughter, "This arrest requires careful deployment, your eldest brother is brave and strategic, but his ability to control the overall situation is not good." ”

"There is Gongsun here, he is responsible for scheduling and arranging, your eldest brother will lead people to arrest, plus the support of His Majesty, this time it is not difficult. You can stay at home without worrying. ”

"As for gunpowder, in fact, Gongsun has already arranged it. Those who didn't steal it, even if they did, it was also a useless defective product that stole chickens and rice. ”

"Yes, Dad." Li Xiaoyue responded, there are really too few things she can do.

After the New Year, it is spring.

The sky is to things, spring is born and autumn is fruitful.

Hard work can be exchanged for harvest.

Grain has always been lacking in the northwest, and when the corn matured last year, she picked the full grains as seeds.

She remembers that corn and potatoes are planted together to promote the growth of both, and she wants to try it this year.

If you want to do a good job, you must first sharpen your tools, and now she has money in her hands, and she will try to make what she knows.

She doesn't have the ability, but she can pay a craftsman to ponder and experiment.

Some time ago, I heard my fifth son Li Changan say, why is the wound inflamed?

If the wound is contaminated with dirt, the wound will become inflamed and festering faster, what is going on? What is there in this dirty stuff that can accelerate inflammation and make inflammation worse?

At that moment, Li Xiaoyue suddenly thought of the microscope in basic science.

The rapid development of Western medicine has a lot to do with their invention of the microscope.

She used to work at school, specializing in cleaning the lab, including cleaning the microscope.

Sometimes it is necessary to remove the microscope and wipe down the parts one by one.

So Li Xiaoyue remembers the construction of each part.

Many things can be made from existing materials, the only thing that doesn't work is lenses.

If you don't have glass, look for crystal.

But now the craftsmen are grinding the lenses, and I don't know if they have been polished yet.

Li Xiaoyue can't help at the strategic level, so she is ready to focus on the small and prepare to get this microscope out.

"Uncle Wang, how many lenses have you polished?" Li Xiaoyue asked, fortunately, I learned optics in junior high school physics.

She also has a bit of a golden finger, and she can basically remember what she learned in her previous life.

Glass, although she knew that it was burned by sand, but how to burn it was a problem.

When the weather was warm, I found someone who fired glass, experimented many times, and burned paper glass.

With glass, is the mirror still far away?

Not far away, of course.

Although there are bronze mirrors now, good bronze mirrors can also find human figures, pale gray-yellow figures.

No glass mirror looks good.

Craftsman Wang smiled, "I have polished more than a dozen pieces, and according to your requirements, we have found the focus, which is much more accurate than our previous operation." ”

Li Xiaoyue's face was delighted, she turned around to look at it, and then said, "Okay, wrap it up for me, and you continue to grind." and these are twenty denarii for your reward. ”

"Thank you, owner." Craftsman Wang smiled and took the silver, "We have found the trick, and we will be able to increase the speed and grind out more in the future." ”

Li Xiaoyue nodded, "Okay, you can grind with water, which is faster and less labor-saving than your manual grinding." ”

Craftsman Wang smiled: "The little one was about to say this, I tried two yesterday, and it was sharpened quickly and well." We will continue to adjust and strive to grind out better and more accurate. ”

"Good!" Wang craftsman should be down.

"By the way, if you have some good ideas, you can try them, don't be afraid to waste things, maybe a flash of inspiration can collide with wonderful ideas."

When Craftsman Wang heard this, his eyes lit up, "My apprentice took two big belly pieces (convex lenses) yesterday and put them in front of his eyes, and as the distance continued to increase, he found that he could see things farther and farther away. ”

Hearing this, Li Xiaoyue's face changed, and she thought of the telescope.

Oh my God, something so important, why didn't she think about it?

At the border gates, the role of telescopes in the war is very large.

Li Xiaoyue took out another ten taels of silver and handed it to Master Wang's apprentice, "Your discovery is very good and useful." Keep up the good work in the future. ”

"Thank you, Mrs. Lee, for the reward." The little apprentice didn't expect that a small discovery would be rewarded for him, and it was specially given to him.

Li Xiaoyue smiled, "As long as you work hard, I won't treat you badly." ”

"Yes, ma'am." The Master and the Master were very happy and grateful.

When Li Xiaoyue returned home, she took out her charcoal and began to draw telescopes, magnifying glasses, and shrinking mirrors.

Measure it, then design out the size and mark it.

She personally found Carpenter Sun and asked him to help make it, "Master Sun, let the others go first, and make this for me first." ”

Carpenter Sun frowned slightly, "What is this for?" ”

Li Xiaoyue didn't explain, took a convex lens, and put it on the paper, "Has this font become bigger?" You're dazzled, this magnifying glass allows you to see the small print. ”

Hearing this, Carpenter Sun's eyes lit up, "This is a good thing." ”

Li Xiaoyue was quite proud, "Hehe, this is just a magnifying glass, there are better things, wait for me to get you reading glasses later, and it will be more convenient to wear them on your eyes." ”

"But first, you give me these things out of wood and put them on for me."

"Okay, it's very fast, I can do it for you today. When it's ready, I'll let the little stone be sent to you. "Carpenter Sun should be done, these jobs are very simple.
