After Hua Qingxue finished talking about Li Jingnan, she remembered that she cared about Fu Tingye.

"How was the general talking to them today?" She asked.

The envoys of Da Liao have been entertained by King Ning's people during this time, and Fu Tingye is not at ease, so he went to visit in person today.

Fu Tingye said: "The Liao people want to buy new weapons from us, just like Nanzhao, and return them to Xi, He, and Mo prefectures as a condition. ”

As he spoke, the corners of his mouth hooked up with a sneering sneer, "What they think is quite beautiful, with a new weapon, they can just snatch back the three states that were sent back, will we do such a loss-making deal?" ”

Hua Qingxue thought for a while, and said softly: "The Liao people's sense of aggression is too strong, and it will definitely not work now...... However, if you wait until next year, it is not impossible to sell ......"

Fu Tingye raised his eyebrows and looked at her, "What's the matter, the new weapon will come out next year?" ”

He knew that Hua Qingxue would let go, and he must be sure to make a more powerful weapon that could restrain Da Liao.

"I guess it should be about the same time." Hua Qingxue smiled slightly, "Shaowen is very talented, and the batch of glassware he has made recently is getting more and more presentable, and I estimate that it will not be long before he can make a still." ”

With the still, Hua Qingxue can show her strength, and what she didn't dare to think about before and what she didn't dare to do, she can give it a try in the future.

"So...... Then I'll drag it out. Fu Tingye touched his beard thoughtfully.

Hua Qingxue asked tentatively: "Can you bring the other three states back as well?" ”

During the reign of Li Jingnan's father, he ceded the six prefectures of Qin, Wei, Yuan, Xi, He, and Mo...... It's okay, but Li Jingnan has a heart.

Hua Qingxue's proposal happened to be what Fu Tingye was thinking, he looked at her with a smile in his eyes, and said: "Don't worry, the envoys who came to visit this time can't be the master, I'll explore the wind first, if the Great Liao Emperor is determined to get your weapon, he should send someone over to discuss it in detail." ”

Hua Qingxue nodded as if she didn't understand, thinking that the peace talks between the two countries really didn't happen overnight.

……

Li Jingnan seemed to be really angry this time, and he never came to Hua Qingxue after returning to the palace.

He is the emperor, if he doesn't leave the palace, Hua Qingxue won't be able to see him, and he has prepared a stomach full of bitter exhortations, but it is useless.

Fu Tingye didn't worry that she lived in such a big house alone, so she bought a family and sent it to her, the man was responsible for running errands and passing on the phone to do some hard work, the woman cleaned and cooked, and there were two daughters, who could just be Hua Qingxue's personal maid.

Hua Qingxue is really not used to this kind of human trafficking in ancient times, but Fu Tingye said that this family is a slave, and if he doesn't sell it to her, he will sell it to other families, and if he encounters an unkind master, the end will only be worse.

Hua Qingxue looked at the patches on the clothes of the family of four, and couldn't bear it, so she left them.

The eldest daughter of this family is called Huan'er, who is sixteen years old, and the youngest daughter is called Xi'er, who is only thirteen years old.

Hua Qingxue was in a complicated mood, thinking that she was twenty years old, and she even had two teenage girls to serve her...... It feels like abusing a minor, which is illegal in modern times......

Hua Qingxue has never used people at home, and she has no experience at all, but fortunately, this family has worked in other people's homes before, and she doesn't need Hua Qingxue to speak, so she can arrange her own work.

She slowly realized the benefits of having someone to serve her.

The most significant thing is that someone has an idea of what clothes and jewelry to wear every day, and someone combs her hair, she really has a headache about the matching of these ancient clothes, and she doesn't know how to comb various hairstyles. Although the two maids were young, they helped Hua Qingxue a lot like timely rain.

I lived in Shengjing City for three or five days, and unexpectedly received a letter from Liang Wensheng, which was accompanied by a deformed mirror.

It turned out that not long after she left, Su Shaowen made a strange mirror by chance in a glass mirror, which was bent and deformed in it, which was very ugly, and should have been destroyed, but because he didn't understand it, Liang Wensheng and Su Shaowen discussed it, and decided to send a letter to Hua Qingxue for help.

Hua Qingxue was happy when she saw it.

This Su Shaowen actually made a haha mirror.

The two of them were stupidly self-examining in the letter, not knowing that they had made a good thing.

The first thought in Hua Qingxue's mind was to give it to Li Jingnan, he would definitely like it!

Then I remembered that the two had a falling out a few days ago, and I felt a little depressed.

Hua Qingxue sat down at the table and wrote back to the two of them, explaining the optical principle of the haha mirror clearly. In fact, it is the unevenness of the mirror surface, which causes the reflection and focus of irregular rays, forming a scattered image.

Hua Qingxue was afraid that they would not fully understand, so she drew a mirror diagram of the four effects of tall, short, fat and thin on the paper, and asked them to make all these kinds of mirrors according to the picture.

Sometimes only by doing it yourself can you have a deeper understanding of the principle.

After writing the letter, she read it again herself.

The correspondence is not as clear and unambiguous as face-to-face communication, and she must ensure that the words and sentences are simple and easy to understand, so as to avoid Liang Wensheng and Su Shaowen not being able to understand nonsense.

Seeing the word "concave and convex mirror", Hua Qingxue was slightly stunned.

If Su Shaowen can make a concave-convex mirror, maybe ...... Can he try something else?

Hua Qingxue thought for a moment, took out a few more pieces of paper, and began to write a second letter.

Haha mirror is actually a kind of concave and convex mirror.

The concave mirror is focused, which is equivalent to the principle of the sun fire in the magnifying glass.

The convex mirror expands the field of view and is equivalent to a corner mirror on the side of the road that can observe the road conditions on both sides.

The light refracted through the convex mirror is reflected by the concave mirror to enter the small hole and converge for imaging, and then pass through a magnifying eyepiece to form a telescope.

That's it...... Telescope!

Just imagine, when the enemy army is still thousands of kilometers away, you can see the enemy's strength and soldier formation at a glance, and prepare in advance, how much help this will be for the battle situation!

This haha mirror, it came at a good time!

Regardless of ancient or modern times, the key to the victory or defeat of the war has long been cracked by mankind, and it is nothing more than three aspects-

First, information transparency. Where the offensive is weak, where there is an ambush, and where there is a breakthrough point, we must clearly grasp it.

Second, firepower. In simple terms, it is attack power, strike ability.

Third, mobility. Soldiers are able to respond quickly and correctly after an order is issued, which tests the flow of information and the deployment of troops.

As long as you have the advantage in these three aspects, you can basically decide the outcome of the battle.

On the third point of mobility, Hua Qingxue believes that with the conditions of the current era, Fu Tingye's army has done its best, and the remaining two points: information transparency, she is expected to have a telescope, firepower, she has earth-shattering thunder, and there will be artillery in the future.

Hua Qingxue's heart suddenly surged.

Just give her some more time......

With a little more time, the Great Qi army will be invincible!

Hua Qingxue carefully drew the structure of the telescope, and rigorously marked the size and angle values, because she was too involved, Huan'er brought dinner, but she directly ignored it.

When the drawings were completely completed, Hua Qingxue raised her eyes and saw that it was already dark outside.

Candles were lit in the room at some point, bright and warm.

Huan'er brought the food that was warmed on the stove, Hua Qingxue stood up and was about to eat, but I don't know if it was because she had sat for too long, and suddenly felt dizzy.

She closed her eyes slightly, and when she opened them again, she still felt top-heavy.

"Let's take the food, I don't have much appetite."

Hua Qingxue held her head and walked in, she thought that she should be too tired, otherwise how could she feel groggy and ......

……

Shengjing Imperial Palace, martial arts arena.

The little emperor was wearing a bright yellow narrow-sleeved military uniform, and his face was stretched and he pulled out a bow-

Sou!

The arrow feathers were sharp, but it missed its head and landed on the periphery of the target.

The eunuch in the distance raised his flag and waved it twice, signaling the target.

Li Jingnan frowned, and threw the bow in his hand aside in anger! The expression was gloomy.

Xiaodouzi lowered her eyebrows and sent a wet veil.

Li Jingnan grabbed it and wiped his hands twice, and said coldly: "Don't practice, go to the imperial study." ”

"Yes."

Since the last time he had a big quarrel with Hua Qingxue, Li Jingnan has been in a bad mood.

The imprisoned palace people have all been released, but Zhao Xi lost his life when he was beaten by the board, and Li Jingnan was upset when he thought that Hua Qingxue was very likely to quarrel with him about this matter, what kind of careless human life, what tyrannical and unkind.

Fortunately, the Queen Mother didn't bother him because of this incident, probably because the life of the slave was not valuable, and Zhao Xi was not killed on the spot, he was sent back to his residence to rest after the beating, and the high fever did not go away that night, so he died of illness, which had nothing to do with Li Jingnan.

For the queen mother, it doesn't matter if the emperor wants to kill the minions, as long as it doesn't hurt the face of the royal family.

No one taught him, Li Jingnan should have felt relaxed, but he always remembered that Hua Qingxue scolded him as a tyrant, and he was so annoyed that he was annoyed!

"I don't know what's wrong! I'm not here for her! Li Jingnan held a few mirror fragments and said to himself, "My gift was broken, don't you want me to be angry?" I didn't cut off his head, he was unlucky...... It's not my fault that he can't stand the fifty boards......"

The more Li Jingnan thought about it, the more he felt that he was right, and the more unpleasant he felt in his heart.

Isn't he just a dog minion, Hua Qingxue said that about him?

Is there still less people killed by Fu Tingye? Why didn't you see her say Fu Tingye?

He just punished a little eunuch...... It's really a big fuss, and he actually said that he would cut off her head, how could it be? She is different from them.

Li Jingnan had to admit that he began to miss Hua Qingxue.

I miss her weird things, and I miss the ease of being with her......

"I've been cold to her for so many days, she should have already reflected, right?" Li Jingnan seemed to be asking Xiaodouzi, and seemed to be talking to himself.

Xiaodouzi hung his head to the side, not daring to speak......

Li Jingnan frowned deeply and said, "But she scolded me for being a tyrant and said that I was unreasonable!" If I get up again, wouldn't it be shameless?! Anyway, I should have asked her to apologize to me first! ”

After he finished speaking, he was silent for a while, probably feeling that it was unrealistic to let Hua Qingxue apologize to him, so he sighed and muttered to himself: "I'm a man, she's a woman, I should let her, huh...... Forget it, don't worry about her......"

Little Bean: "......"
