The best old woman is too fierce, stepping on her ex-husband and beating up her traitorous son!

Gongsun Lian smiled when he heard this, "Now everyone from the household department has started to use numbers, and there is a new accounting method. It is indeed clearer, better and easier than before."

Li Xiaoyue nodded, "Many people have always rejected Fanbang's things. In fact, there are people outside the world, and there is a heaven outside the world."

"There is also culture in Fanbang, and there is also a good side. We cannot be too high-minded. For those foreign things, we must take the essence and discard the dross and make use of them."

Hearing Li Xiaoyue's words, Gongsun Lian smiled and said, "When I finish things here and the border is stable, I will revise it with you."

Li Xiaoyue nodded quickly. Gongsun Lian's knowledge of Dayan became more proficient and thorough.

With him by my side, I will definitely be able to compile better.

"Okay. Then I'll wait for you to come back! I'll come up with what I can think of and what I can make up first."

"When the time comes, if you find any omissions, you can help me add them in. If there are mistakes, you can help me correct them."

"When we compile these, I will teach them arithmetic in the school. These things are more useful to them than the Four Books and Five Classics."

Gongsun Lian was convinced.

After having dinner here, they went to pay their respects to Old Man Li.

Old Man Li and Brother Li liked their sister's gift very much.

This daughter is quite good, not only for Gongsun Lian, but also for her biological father and biological eldest brother.

Others are greedy and want it too.

Li Xiaoyue smiled and said, "It's not easy to polish the lenses now. When there are more lenses, I will make more."

"Okay, such transparent jade is rare. Don't embarrass Xiaoyue." Of course, Old Man Li would not let his daughter complain and came to her rescue.

Li Xiaoyue smiled and said, "If there are good things in the future, I will definitely get more of them so that everyone can have them."

Gongsun Lian set out on his journey, and Li Xiaoyue and Mrs. Gongsun came to see him off.

Gongsun Lian said softly: "Xiaoyue, please."

"Don't worry, Chang Huan and I will take care of the old lady. But you and your eldest brother should be careful along the way."

"Okay!" Gongsun Lian agreed, got on the horse, and left quickly without looking back.

He is afraid that if he looks back, he will be reluctant to leave.

Because of the need for a quick victory, Gongsun Lian did not ride in a carriage but on horseback.

Mrs. Gongsun just looked at her son's back, just like before, watching her son leave. After she couldn't see her son's back, she began to look forward to her son's return day by day.

Seeing the old lady not moving for a long time, Li Xiaoyue stayed by her side.

"Xiaoyue, let's go back. I want to eat leek dumplings for lunch, okay?" After a while, Mrs. Gongsun said with a smile, becoming the kind and smiling old lady again.

Li Xiaoyue was stunned for a moment, but when she saw Mrs. Gongsun smiling, she also smiled, "Okay, I'll give it to you right away."

In fact, it is not a leek, but a leek yellow.

Apart from radish and cabbage, there seems to be no decent vegetables in winter.

There are leeks, but they don’t grow at all in winter.

So Li Xiaoyue started growing leeks in the greenhouse. Not to mention, they actually grew and tasted pretty good.

During the last Chinese New Year, I gave some to the old lady, but I didn’t expect that she would like to eat them.

"Old madam, how about you come back with me and let's make dumplings together?"

"Okay! Do it yourself, it will taste better." Mrs. Gongsun distracted her attention by doing things, so that she would not miss her son who was traveling far away.

Old Man Li didn't have such a big reaction. Firstly, he had many sons, and secondly, things were actually not difficult.

As long as you are careful and deploy well, you should be able to come back safely.

If those fine works are removed, Da Yan may be able to settle down for some time.

Let's say that Li Changfu came to Zhenxiguan camp with a telescope. Huo Yingjie was handling official duties when he heard from the guards around him that Li Changfu was here. He thought something had happened at home, "Please come quickly."

Li Changfu walked in under the leadership of the guards, "See General Huo."

"Changfu, why are you here?" Huo Yingjie asked hurriedly, but he was relieved to see that Li Changfu was not in a hurry.

Li Changfu took out the telescope from his pocket and handed it to Huo Yingjie, "General Huo, this is the telescope my mother made. It can see far away."

Hearing this, Huo Yingjie looked surprised, "Then I have to take a good look." After saying that, he put it on his eyes and closed the other eye.

When Huo Yingjie looked at it, he actually saw a soldier far away with a pockmark on his face.

He took big steps himself, actually fifty steps, and he could see clearly.

He adjusted the length and looked farther and farther, which made Huo Yingjie very excited.

"With this thing, it's like having an extra pair of eyes!"

"If the scouts take this thing to the front to inquire about information, not only can they hide themselves better, but they can also see more clearly and see more."

Li Changfu nodded, "Yes, General Huo. There is also a magnifying glass here. I can do an experiment for you!"

Huo Yingjie was very interested and followed him outside.

Li Changfu found a rag, then took out a magnifying glass and pointed it at the sun. The sunlight gathered into a small point and fell on the cloth.

It was noon, the warmest time of the day.

Because it is the first month of the year and the temperature is still very low, it takes a little longer to light the rag.

A quarter of an hour later, there was a black spot on the fabric. The black spot was getting bigger and bigger, and smoke was also burning.

Finally caught fire.

Huo Yingjie was stunned, "Oh my god, how could there be such a magical thing!"

"If you don't bring a fire break, or if the fire break gets wet, and you have this thing on you, you can make fire as long as there is sun!"

Li Changfu nodded, "Yes, there is another function, it can enlarge the words on the book."

Hearing this, Huo Yingjie quickly took it over and tried it.

"Changfu, go back and tell Mrs. Li to make me a magnifying glass and telescope. No matter how much it costs, I will buy them. My father's birthday is coming soon. As a gift, he will definitely be happy."

Li Changfu nodded, "I will tell my mother when I get back. After all, there are not many such translucent jade, and it also needs to be polished, which takes time."

"The general's birthday is in two months. Even if the craftsmanship is complicated, it can still be made in time."

Huo Yingjie thanked him, "Please!"

Li Changfu came out of the military camp and rode back to Lanshan County.

He went to the briquette shop and then went to find Li Baqiang.

Give Li Baqiang a telescope and a magnifying glass.

Li Baqiang couldn't put it down. Collecting all kinds of information and performing various tasks like them requires a variety of tools.

These things his aunt gave him can come in handy.

"Changfu, how much does it cost? I'll give it to you!"

Li Changfu waved his hand, "No need to pay, my mother personally told me to deliver it to you!"

"You are doing things outside and running around here and there. These things are more useful in your hands."

Hearing what his cousin said, Li Baqiang nodded, "Yes, this thing allows me to see far away, so that I won't be easily discovered when I spy on some people."

"Recently, my grandfather asked me to keep an eye on the Liu Mansion, which really cost me a lot of effort. After all, Liu Zicheng is a general, and there are many guards in the manor. It is easy to be discovered if you get too close." (End of Chapter)
