After the student finished speaking, he bit the tip of his pencil and went to the front, looking at the picture intently, while discussing it with the classmates next to him.

Mu Bin has been serving here for half a month, and has a general understanding of the basis of mechanical drawing, but he is still very far from understanding a picture, and he can only pick up the simplest picture to look at, and then outline in his mind what the picture wants to express, what should the real thing look like?

"As for the internal combustion engine, didn't we make several tractors?" Zhu Gaoxian said, "The drawings of the tractor, I have hung them in the drawing room, you can take time to take a look, or you can get a tractor to do a physical comparison." ”

"Teacher, why can't I understand here?"

A student pointed to a structure on the steam turbine and interrupted Zhu's words.

Zhu Zhaoxuan pinched a cold sweat for this student, since Zhu Gaoxian is a teacher and a prince, how can anyone interrupt him when he speaks?

Zhu Gaoxian walked over, as soon as he passed, many students surrounded him, Zhu Gaoxian told them, "Here is the rotating part, here is the static part, here is the coupling, what is the coupling I talked about before, as the name suggests, it is to connect the two shafts with a device, here, it is to achieve linkage." ”

Zhu Zhaoxuan didn't understand, he saw Mu Bin passing, and what shocked him was that Mu Bin was still taking notes.

The two met at the palace banquet yesterday, although they were not very familiar, but they definitely knew each other, Mu Bin saw that it was Zhu Zhaoxuan, nodded with him, and pricked up his ears to listen to Zhu Gaoxian's explanation.

"Many metal and metal connections, do not use hard connection, but use soft connection, there is a sealing effect, at this time, the first thing you think of is, the ambient temperature here, and the working conditions, what kind of performance of rubber is needed, whether we can change the rubber formula, to achieve our purpose."

Zhu Gaoxian's lecture lasted for almost an hour, and in the middle of the conversation, the dog brought tea in several times and glared at these students fiercely, but no one paid attention to him, and everyone was working hard to write, for fear of missing a word Zhu Gaoxian said.

Zhu Zhaoxuan listened to the book for a long time, until Zhu Gaoxian swallowed a mouthful of saliva, his throat was so dry that it was about to smoke, he took a sip of tea, "Okay, you can't eat a big fat man in one breath, that's all for today, it's also the end of the month, you should also have a winter vacation, and the winter vacation will start tomorrow......"

"Whew!"

There was a lot of lamentation, and it seemed that everyone didn't want to go home for the New Year.

"What, don't you want to go back for the New Year?" Zhu Gaoxian said with a smile, "You don't want to go back, don't the adults in the family want you to go back?" ”

"Teacher, don't you know, my father said, as long as you can learn more things from the teacher, students can pass through the house three times without entering." One student said poorly.

"Yes, my father also said that if I dare to be lazy, he will beat me to death, and said, I have studied well this year, and I will give a big red envelope. I don't have to go home for the New Year! "The other one scrambled to speak.

"That's okay, the eighth day of junior high school starts, and the seventh afternoon of junior high school reports here, Wang Ji, I remember that he is from your group, and the dinner on the seventh night of junior high school is his."

"Okay!" The student was still very happy, raised his hand and said, "Teacher, I live in the city, can I go back until the twenty-eighth of the lunar month, I want to see more drawings here." ”

"That's no problem, but you have to pay attention to confidentiality, these drawings are all priceless treasures of the academy, you can lose them, you can't lose them."

"Teacher, no problem, it's on me, people are in the picture, and people are not dead."

Zhu Gaoxian was too lazy to be poor with them, and told him a few words to pay attention to safety, and then led Zhu Zhaoxuan out, Mu Bin naturally wanted to stay and study more, since he entered the academy, he refused to delay at all, and he didn't need to go back to prepare New Year's goods, so naturally he wouldn't leave the academy.

"Brother, what exactly do you teach in this academy?" Zhu Zhaoxuan hadn't gone out yet, so he couldn't help but ask.

"I studied mechanical design and manufacturing."

Zhu Gaoxian wanted to say that mechanical design, manufacturing and automation, but at the moment, it was still far from automation, and he didn't say it.

"What do you do?"

"It's about designing some machines and letting them take the place of people." Zhu Gaoxian couldn't explain these things to Zhu Zhaoxuan for a while, so he proposed, "You can go find Xia Yuanji, he has a lot of things I made, let him show you, you can roughly know what's going on." ”

Zhu Zhaoxuan knew that Zhu Gaoxian must be too busy to receive him, so he said "bother", and couldn't wait to leave the academy and go to Xia Yuanji.

"Wait!" Zhu Gaoxian pondered for a moment and said, "There is something, I want the prince to do me a favor." ”

"Brother, you are too polite, if there is anything, my brother can send it, why bother to say help."

Zhu Gaoxian was not polite to him, "Guo Ying is a good person, he was originally Emperor Taizu Gao's person, and later, he went forward and succeeded Zhu Yunwen, and he was also loyal." ”

Zhu Zhaoxuan chuckled in his heart, what does this mean? In other words, it was his father's foreign family, and it didn't have much to do with him.

"You go and talk to Guo Ying, just say, His Royal Highness the Second Prince wants to see his girl, there has been a blind date since ancient times, purely say two words, don't let outsiders know, even if you have an understanding of each other's temperament, it's not a big deal, if you look at each other, it's naturally a good thing, if you don't see the right eye, don't force it, let him look at my face and give him a chance."

What's going on? Is it appropriate for a lonely man and a widow to speak?

But Zhu Zhaoxuan knew that this matter, not to mention the Guo family, even he had no qualifications to refuse, so he hurriedly agreed, "It just so happens that Marquis Guo wants to invite me to sit at home, and my brother will leave this matter to me!" ”

"Go ahead!"

The dog finally had some free time, and said to Zhu Gaoxian, "Your Highness, Shen Chunhong's side, I have looked for His Highness several times, His Highness is very busy, he asked the slave to talk to him, saying that ten bicycles have been made, and many people are looking for him to buy them, he really has no choice, and I implore His Highness to call the shots." ”

Zhu Gaoxian thought for a while and said, "You take 30,000 taels of silver to find Shen Chunhong, and say, I want three bicycles, and the remaining seven bicycles, let him hand them over to Baoming Auction House." ”

"Yes!"

Now that the year is coming, Zhu Di is worried about the reward, and when he heard that his youngest son is back, he hurriedly put down the proposed article and got up to welcome him.

When the father greeted his son, it was naturally impolite, Zhu Di arrived at the door, turned back, waited for a while, and didn't see his son come in, so he couldn't help asking, "What about the fourth?" It's not that he's back, why didn't he come to see me? ”

Huang Yanle said, "If you go back to the emperor, His Royal Highness the Fourth Prince has not yet entered the palace gate, and he was greeted by Mama Tang, and I am afraid that he will be in the palace of the queen mother at this time." ”

"Let's go, I'll go see the queen by the way!"

Zhu Di didn't change his clothes, so he went to Kunning Palace, and when he entered the palace gate, he heard the laughter and laughter coming from inside, and heard Zhu Gaoxian say, "My son spent 30,000 taels of silver and bought three bicycles, and he is going to pay filial piety to his father." ”

"What does your dad want three bikes for? Ride one in the morning, one in the afternoon, and another in the evening? "Queen Xu is really happy, her son went to the academy, and after going for more than half a month, she thought about her son very much.

"How can there be, Daddy Ninety-Five, how can you do such a dangerous thing as riding a bicycle? The son is planning to give this bicycle to his father, so that his father can reward the hero. There is also a sewing machine, which the son thinks can also be used as a reward. ”

"Okay!" Zhu Di was happy when he heard this, stepped in, and there was a sound of kneeling in the palace, he held his son with one hand and his wife with the other, "Family, don't be polite!" ”

In front of his son, Xu didn't say anything about etiquette, and the family of three sat down, and Zhu Gaoxian said to his father, "Dad, my son is thoughtful, right?" Dad, don't you just have no money? Do you want your son to tell Xia Yuanji about the method of making white sugar, and also give the household an extra income? ”

Where is Zhu Di always taking advantage of his son, and said, "Or, fourth, how many Zhuangzi do you have in your name, and Dad will give you a little more land?" ”

"Yes, Dad, don't, my son was about to say, don't enjoy the fields at every turn in the future, the land has been circled by those officials and gentry, how do you let the people live?"

Zhu Gaoxian said, "This is to reward people, more is a method, in the future, if you don't have anything to reward, you might as well reward a few admission places to the ministers, let them come to their sons to study, this is also a grace!" ”

"How can there be such grace?"

"Why not? My son's students here want to enroll, the first thing is to pay taxes and serve, if you give them a place to enroll, this is equivalent to exempting them from taxes in disguise, why are they unhappy? ”

The dog handed a list to Zhu Gaoxian, Zhu Gaoxian handed it to his father, and Zhu Di looked at it, three bicycles, ten sewing machines, ten textile machines, and sweet potatoes and peppers.

These are all prepared by Zhu Gaoxian for his father to reward the minister, Zhu Di feels that compared to Jinyu Grange, this is really a little unproductive.

However, let him refuse his son, let his son can't get over it, he can't bear it, think about it, forget it, only reward these first, and then take other benefits to fill it up.

Seeing that his son and his mother had been talking for a while, Zhu Di was a little impatient and coughed, "You are so old, don't stick to your mother, you should also learn to help your father deal with some things, Dad is getting older, and now he is getting less and less energetic, and you don't want to feel sorry for your father." “

As soon as Zhu Di said this, Xu was very distressed, and hurriedly pushed his son, thinking that he would make some tonic soup for his husband for a while, and instructed, "Listen to your father and help your father more!" ”

Zhu Gaoxian said in his heart, you don't have enough energy, why do you still have five northern expeditions? Who is this fooling?
