He was betrayed at the beginning, from a cake seller to a wealthy person

Since a person has decided to adopt him, his name must be changed.

Lu Yan's attitude was very resolute: "Isn't Pan'er just looking forward to having a son? What nonsense, it must be changed."

Lu Sheng: "Why don't we go ask her what she wants to be called?"

"She's only five years old." Lu Yan was a little hesitant: "When I was five, I was still hesitating whether to call her Leng Bingning Aiyu Meng Cuishuang or Pink Butterfly Rose Princess. You can't trust the aesthetics of this stage."

Lu Sheng:? ? ?

what? ? ?

Having said that, I went to ask the child what he wanted to be called.

Pan'er didn't know how to read at all, so asking her to name herself was simply embarrassing her. She looked at the two of them with round eyes and asked for help: "You can name me anything. I haven't read a book." , I can’t get up by myself.”

Lu Yan thought about it and suggested: "How about Lu Wei? The only Wei, do you like him?"

The little girl's eyes lit up when she heard the only two words, and she nodded quickly: "I like it!"

Lu Yan also nodded: "Okay, from now on you will be called Lu Wei."

Lu Yan thought very well, what nonsense is Pan'er, the little girl is the only one, and her name is Lu Wei.

She didn't expect that she had inadvertently set a new flag.

Lu Wei was recuperating in the room. Lu Yan and Lu Sheng were both busy with other things, so they gave her a few words of advice and left.

Lu Sheng was finally able to lead people to patrol the streets and sweep the snow. The houses in Liaozhou were built quite solidly, and the roofs were not damaged. The young and middle-aged people in the houses had already gone up to the roofs to sweep the snow off. Lu Sheng, who only had the elderly, the weak, women and children at home, took the servants to the roofs to sweep the snow and reinforce the roofs.

There was also thick snow on the branches. Lu Sheng led people to climb up and shake the snow off to prevent it from accumulating and eventually breaking the branches. Several young men climbed up to different trees and shook their branches together. Large tracts of snow fell from the trees, as if it had snowed again.

Lu Sheng wore the boots made by Lu Yan for him. The outer layer was cowhide and the inner layer was rabbit fur. He was not cold at all, jumping up and down in the ice and snow. Several officers were submissive. When they wanted to take a break, they saw that Lord Lu was still working hard, and they couldn't sit still.

This is the complexity of being a leader among peers. They don’t act like high-ranking officials, nor do they have a bad temper, but they are full of energy.

Lu Yan also has a lot to do here. The most important thing is to polish the stone mold quickly. It has been snowing for a few days and the temperature has dropped rapidly. There is a kang and a coal stove in the house. She dare not open the door or windows. It was very dark inside, and Lu Yan urgently needed to replace the glass window.

This time the snow stopped after five days, and the temperature dropped completely. I heard from the old people that the snow will become more frequent in the future, and it may start again at any time after a few days. As soon as Lu Yan finished the mold, she took it to the brick kiln on the outskirts of the city.

In the past few days, they had baked a basket of glass ballast blocks for Lu Yan. Lu Yan was very happy and found it just in time. She spread the glass blocks over the stone mold and sent it to the kiln to wait for the kiln to be opened.

Having nothing to do, a few craftsmen chatted with Lu Yan, and Lu Yan taught them how to grind a convex lens. This thing is easy to make, just take a palm-sized piece of glass and grind it on a hand file, and you can grind one in less than half an hour.

The craftsmen didn't know what Lu Yan was going to do. Lu Yan placed three small stones of similar size on the ground and adjusted the height with a convex lens for them to see.

When the craftsmen looked at the center of the convex lens, they all exclaimed, "Oh! It's getting bigger!"

Several craftsmen swarmed over to take a look, and after seeing it, they exclaimed in surprise: "It really has grown bigger!"

"what happened!"

"Miss Lu? Why is this?"

To talk about the imaging principle of convex lenses, we have to start with the refraction of light, but Lu Yan obviously didn't want to tell them, and pointed to the convex lenses they were holding: "It's the one you're holding. I'm not going to teach you how to sharpen it." Well, it has the ability to amplify things.”

Lu Yan waved her hand: "You put a wooden frame on it and a handle, and it becomes a magnifying glass. It has many uses. If it's summer, you can also use it to light a fire."

The craftsmen were confused: "Light a fire? How to light it?"

Lu Yan gestured with it, gathering the sunlight into a small dot on the grass, and pointed: "Gather the sunlight on that point, and it will be lit in a moment."

The craftsmen were eager to try: "Let's try it! I want to see it!"

Lu Yan refused directly: "I said summer! You can't order it now!"

The surrounding environment is now about minus 20 degrees Celsius. If you want the paper to reach the melting point and burn, wait for her to die.

When the kiln finally opened in the afternoon, Lu Yan couldn't wait to cut the glass out of the mold, and finally got a large piece of glass about one foot long and wide. Her hands were shaking with excitement.

Lu Yan brought two craftsmen who were good at carpentry back home, and they made a wooden window according to the size of the current windows in the house, firmly inset the large piece of glass in the middle, and directly replaced the original oil paper window.

Lu Wei had been sleeping in Lu Yan's room for the past few days. When he saw the window being replaced, he came over curiously to watch. The oil-paper window was replaced with a glass window, and the sunlight shone into the room through the transparent glass, instantly making the room brighter.

Lu Wei's eyes sparkled as he touched the glass and couldn't let it go: "Oh my God! What a wonderful thing this is!"

Lu Yan chuckled: "This is called glass. We'll use it in our house first, because I'm going to teach you how to read in two days. We can't keep our eyes so dark in the house."

Lu Wei turned around abruptly and looked at Lu Yan: "I... can I learn to read now?"

"Of course." Lu Yan gave her a puzzled look and said, "You are my daughter now. I cannot tolerate you being illiterate. When I open the academy, you have to go to school. You must go. You cannot not go."
