Open the window and let the wind outside blow into the study, and some rain will float in, but it is very gentle. Take out the books in the book bag and see another book on the desk. This book has no name, but it has a very thick book cover. Open the book and you can see the sloppy handwriting written inside.

"Is this what the teacher has been writing?" Li Xiang originally thought that this book was written by the teacher, but she didn't expect to put it aside casually and looked at the content on it, "Sure enough, they are all written in these fonts."

Li Xiang looked through pages and pages and found that there were many words that he could not understand. Now only his master's wife and brother Gu Xiao could understand. The strokes of these words were simplified by the current characters. Some of them can be identified, while others looked much more difficult.

In addition, the handwriting is so sloppy that I can't understand what it says.

"Can you understand?"

The voice of speech scared Li Xiang so much that she was shocked. She looked up and saw that her teacher was holding two bowls of noodles, and she was busy putting down the book in her hand, and hesitated: "Teacher..."

"What's wrong?" Gu Qing looked at Li Xiang and said a little overreacting: "I made it by myself after taking a bite of fried noodles."

"Students should not read the teacher's books at will." Li Xiang said respectfully.

"It's okay, you can read the books here at will, and that little guy Gu Xiao doesn't read much." Gu Qing said while eating fried noodles: "Eat it, it won't be delicious if it's cold."

"Yeah." Li Xiang held up a big bowl bigger than her face and sucked the noodles, watched Gu Qing cross her legs, sat by the window while watching Yu Jing while eating noodles, as if she didn't care about her peeking at the book.

After eating the noodles, I put the bowl aside and focused on writing the school's homework left by the master of the academy. After finishing writing, it was already late, and Gu Qing had long stopped sitting by the window. The laughter from home must have been that Brother Gu Xiao had come back.

After packing up his textbooks, he walked out of the study and saw Gu Xiao and his younger brother Gu Xue bragging about the various things in the academy.

Gu Xue looked at Sun Simiao's medical books and was completely uninterested in saying this to Gu Xiao, but Gu Xiao was very excited.

"Li Xiang, come here." Gu Xiao greeted and said, "I have earned 300 credits in the academy today. Do you think I am awesome?"

"Awesome." Li Xiang echoed.

"Haha." Gu Xue sneered and said, "I don't know who owed my mother tens of thousands of dollars."

A basin of cold water poured on Gu Xiao's head, and half of his enthusiasm just now was gone.

"How long will it take to clear it?" Gu Xue said with a calm expression on the medical books.

"I..." Gu Xiaoyu said after suffocating for a while: "I will definitely pay it back. In less than three years, you can wait and see, hum!"

Li Xiang saw that Gu Xiao was a little careless, but Gu Qing's second son Gu Xue was relatively indifferent. He was not as approachable as Gu Xiao, but Gu Xue was more calm.

"Prince, don't learn bad things from this brother." Gu Xue whispered.

Seeing that his eyes were still looking at the medical book without raising his head, Li Xiang smiled awkwardly and said, "No, Brother Gu Xiao is not bad either."

"Is that so? There is a saying that birds of birds gather together." Gu Xue finally raised her head and looked at Li Xiang and said, "It is said that my brother has had a lot of contact with Zhang Yugong's men recently. Moreover, the master and grandfather said that those guys were the ones who killed people on the battlefield without blinking. After hanging out with these people, they will become bad even if they are not bad. Your Highness, do you think so?"

"This..." Li Xiang was really asked by Gu Xue.

Gu Xue continued, "Crown Prince, my brother is a desperate person who wants money. How about you studying medical skills with me, my master's grandfather and Princess Jinyang sister?"

"What?" Li Xiang couldn't get in a hurry for a moment, so why did she suddenly get into medical skills?

Gu Xue then whispered: "Medical skills are profound, but it's much more interesting than my brother's money."

"I..." Li Xiang glanced around and said, "I forgot to wash the dishes after eating noodles. I'll go wash the dishes first."

After saying that, Li Xiang hurriedly ran away. Gu Qing's children had quite different personalities. The child of his aunt and teacher was Gu Ling. Now he had just learned to speak. Gu Xue was taciturn in character, while Gu Xiao was more lively.

Gu Xue has been learning medical skills with Sun Simiao. Gu Xiao has liked money since he was a child. So what will happen to Gu Ling in the future?

After dinner, Gu Qing took Fan Jian out of the house.

Fan Jian followed Gu Qing all the way and said, "The head of the family, the ore has been dragged out of the palace, but I don't know how to use it when I arrived at the factory. The large engine seems to have been completed."

Listening along the way, Gu Qing came to the factory. The weather was still a little cold, but Zhang Jie was sweating profusely in the factory. When he saw Gu Qing coming, he wiped his sweat and said, "Mr. Gu Hou, you are here."

"How is it?" Gu Qing asked.

Zhang Jie took out a sharp stone from the side and said, "Master of the family, is it such a stone?"

Gu Qing took the stone and the material looked like diamond. It seemed to be polished and the head was very sharp but conical.

"It was like this when I brought it over, but how can I cut the glass just by just a small piece?" Zhang Jie said, pouring cold water into his mouth.

"You spread the glass flat first." Gu Qing said, tied a piece of gold and steel stone that was only the thickness of a pen pole to a piece of wood. After Zhang Jie laid the glass, Gu Qing looked and said again: "You can use something to support it in the middle, leaving a part of it hanging in the air."

"good!"

Zhang Jie immediately took care of several workers to do business.

After thinking for a long time, Gu Qing thought about the technique of cutting glass in later generations. Several woods supported each other and made a simple compass. If the force was higher, it would be better to use iron as a bracket, so that the force of diamond would be better.

"All right, Master Hou, can you see this?"

Gu Qing looked back at the glass and came to the hanging side, but the glass was not very thick.

Fan Jian also looked at it, watching his home owner find a fulcrum on the glass using the things he had just made, and then began to slide around the fulcrum. The glass made people rubbing their teeth.
