"Do you like it?" Li Xiaoyue chuckled, and she also asked Carpenter Sun to carve bamboo on it herself.

Gongsun Lian nodded, "I like it, I like it very much." With this, it is possible to see farther, which is of great military significance. ”

"On the lookout, if you have a telescope, you can detect the enemy earlier, and you will have more time to prepare."

Li Xiaoyue nodded, "You've been here lately, and I've done a lot of things." I'll introduce you when I'm free. ”

"Good!" Gongsun Lian was eager to try, and especially hoped that Li Xiaoyue would share the joy of life with him.

The old lady of Gongsun saw that Li Xiaoyue and Gongsun Lian were chatting speculatively, and smiled.

That's good!

If a son can have someone to talk to, he will not be lonely and lonely for the rest of his life.

Li Laohan sighed that his daughter is good-looking, and Gongsun Lian is also good-looking.

His daughter must have agreed to the marriage because of Gongsun Lian's good looks.

The moonlight outside is very good, and after eating, we went out for a walk together.

Gongsun Lian smiled, "Xiaoyue, what have you been doing lately?" ”

Li Xiaoyue held a fan in her hand and said with a smile: "I'm compiling a book by combining Dayan's arithmetic with Chinese characters and Fanguo's numbers." ”

"In this way, many people can learn arithmetic, at least they can use it in their daily lives. You don't have to encounter something, just break your fingers, and you can't wait to break your toes. ”

Gongsun Lian's eyes lit up, "That's really practical, you must show it to me when the time comes." If it's really good, I have a printing shop, and I usually print some subsets of scriptures and histories, and I don't have much work. ”

Li Xiaoyue nodded, "Okay, but I think the current engraving printing is too wasteful." To print a page, you need to engrave a wooden board, a subset of history, these books are better, some books are not large-scale, and they will not be printed so much, and it is a bit wasteful to use engraving, and the cost is too high. ”

When Gongsun Lian heard this, he was surprised, "Xiaoyue, then what good can you do?" ”

Li Xiaoyue thought for a while and said, "I thought about what words I needed to use if I carved the characters on one separately, so I would combine these words together." ”

"When you're done with it, take it off again. It can be used again next time, which can save cost and time. ”

Gongsun Lian applauded and said with a smile: "Yes, this is a good idea. The next step is what material to use to engrave the words, and what to use to glue the words together one by one. ”

"Your idea, I'll tell the shopkeeper and the craftsman of the bookstore and let them figure it out."

Li Xiaoyue nodded, "Yes, I only know that it should be possible to do this, but the specific materials used need to be tested again and again by craftsmen." ”

"What else is there?" Gongsun Lian was curious, in his eyes, Li Xiaoyue was like a treasure trove.

Li Xiaoyue thought for a while and said, "Chang'an has been thinking about how dirty things will cause the wound to become inflamed and suppurated, but I don't know why this is happening? What's in the dirt? ”

"I wondered if I could use some external tools to see what's inside. I discovered convex lenses and concave and convex lenses, and I started researching lenses. So far, it has been magnified twenty times. Although it is not completely visible, there may be a way to make it bigger with improved lenses. ”

"Twenty times magnification?" Gongsun Lian was stunned for a moment, unable to believe it, "If it wasn't dark, I would have liked to watch it now." ”

Li Xiaoyue pursed her lips and smiled, "I also found that when Uncle Zhou was firing porcelain, his little grandson put a lot of sand in the mud, and as a result, a material with a glazed texture was burned." ”

After inquiring, I found out that it was mixed with sand. So I used sand for experiments, and I actually burned out the glass. Although the quality is not good, it should be that there are too many impurities in it, or there are other reasons. After a lot of experimentation, you should be able to make glass. ”

Gongsun Lian was dumbfounded, he had only been away for a few months, and he didn't expect so many interesting things to happen around Li Xiaoyue.

He couldn't wait to take a closer look, and he was even more looking forward to Li Xiaoyue's more discoveries.

"Xiaoyue, I feel like I'm with you, I feel different every day, it's very novel."

Li Xiaoyue shook her head and disagreed, "Actually, I'm not as good as you, and my usual life is also very dull, and there are not so many things to rise about." ”

"If you feel unhappy with me one day, you can bring it up with me directly, don't force yourself."

"Life is short for a few decades, you don't have to compromise for anyone, it's better to live happily and comfortably."

Gongsun Lian was slightly stunned, "Xiaoyue, don't think about it, this is my true thoughts." ”

"This is also my true thought, I didn't agree to your proposal before, but also because I didn't want to be tired of each other, and in the end I couldn't even be a friend."

"I think it's great if there are some things that can be said directly, so that people don't have to guess each other's minds."

"Just like at the beginning, if Liu Yunde didn't have anything to do outside, he would go home and tell me that he was very unhappy with me, and I could let him go, and I wouldn't force him to stay."

"What I hate is that he eats what's in the bowl and looks at what's in the pot. When people are gone, they still want to take all this at home. ”

Gongsun Lian laughed, "Although it is very unkind, I am really grateful to him now." ”

"If he doesn't spend time outside, it won't be my turn!"

When Li Xiaoyu heard this, she couldn't cry or laugh, and reached out and twisted Gongsun Lian's arm, "What are you talking nonsense!" ”

Gongsun Lian held Li Xiaoyue's hand smoothly, "I didn't talk nonsense, but told the truth." ”

A cold wind blew, and Li Xiaoyue shivered, "It's not early, you should go back and rest!" ”

Gongsun Lian nodded, "Okay, I'll come to see you when I'm done dealing with the affairs of the Dongshan Military Camp." ”

"In another month, it will be the day we get married. Let's do well in the future. ”

Now that the border is stable, there are not many places to worry.

As long as he takes care of the military camp and secretly coordinates the detailed work in the Treaty Country, he can be idle.

Sending Li Xiaoyue back, Gongsun Lian returned home in a happy mood.

After three days in the Dongshan military camp and everything was dealt with, I went down the mountain.

However, he didn't come to Li Xiaoyue, but to find Doctor Liu.

Doctor Liu was slightly surprised when he saw Gongsun Lian coming, "Why is Mr. Gongsun free to come over?" ”

Gongsun Lian smiled, "Of course there is something to do, you also know that I am going to get married next month, you give me a pulse." ”

Hearing this, Doctor Liu raised his eyebrows, "Didn't I show it to you before, it's all right!" The cave house is fine, even if you have a baby, you should be fine. ”

Gongsun Lian was a little embarrassed, "I only ask to be able to do the things of husband and wife, as for having children, then forget it!" Xiaoyue is not young anymore, and she doesn't want her to experience the pain of childbirth again. ”
