Sun Xian explained to Tang Ding, but Tang Ding still didn't understand. He climbed up and down and looked around curiously.
Ignoring him, Han Du folded his arms and frowned at the locomotive in front of him.
After a while, I sighed helplessly: It's a pity that I didn't study mechanics before and didn't understand this thing at all. Otherwise, there is no need for Sun Xian and others to slowly explore it. Wouldn't it be better to just create it ourselves?
"Sir, this thing is too heavy. It's difficult for a steam engine to push it." Sun Xian's face was filled with bitterness.
He had tried hard for so long, but he couldn't pick up the speed. And he also knows the reason. First of all, the power of the steam engine is too small, but if you want to get more power, you must make the steam engine bigger.
It can be done, but the locomotive will become larger and heavier, making it more difficult to push.
Secondly, the weight of the locomotive can only be reduced as much as possible while the steam engine remains unchanged. But this cannot be reduced indefinitely. If the steam engine boiler is made too thin, it will explode.
Han Du lowered his head and thought for a moment, and suddenly remembered the steam train he had seen in the movie. It seems that when it first started, the speed was very slow. The speed of steam trains can only reach a satisfactory speed after a long period of continuous acceleration.
The current train tracks are too short, and there is no way for the steam engine to increase the speed.
"The tracks are too short."
"Sir, what did you say?" Sun Xian didn't hear clearly.
Han Du looked at him and nodded affirmatively: "I said, the rails are too short. Maybe you can lengthen the rails and try again."
】
"It's so easy to lengthen the rails?" Sun Xian was stunned for a moment, then nodded: "Okay sir, then I will lay the rails directly to the courtyard wall and try again."
Han Du shook his head, "It's too short, not enough."
Sun Xian was stunned for a moment. It was a hundred feet from here to the courtyard wall. Isn't this enough?
How long should it be?
After thinking for a while, Han Du said: "Let's go directly to the racecourse."
"Racecourse? Sir, this is more than ten miles away from the racecourse." Sun Xian was shocked.
"Fix!" Han Du decided with a wave of his hand.
However, Sun Xian did not agree directly. He frowned and raised the difficulty: "Sir, there is someone else's land so far apart. Do you want to buy it all?"
"Then buy it!" Han Du nodded, and then changed his tone: "However, you don't have to buy it all, just buy the railway track and the land one foot wide on each side!"
That's pretty much it, Sun Xian breathed a sigh of relief silently. He just thought that the Duke wanted to buy all the land along the way. Although the town government could afford it, it was not necessary!
"But Master, if we only buy this little, will others be willing to sell it?" Sun Xian seized this opportunity and asked quickly.
Han Du nodded indifferently: "Just raise the price. I don't think anyone will take advantage of it."
"The price is not important. What is important is that you have to plan the route first. It is best to lay the rails as flat as possible, and the foundation must be very stable."
"Don't worry, sir, the student knows what to do." Sun Xian promised Han Du with a slight hand.
"If you need money, just go to the mansion and ask Uncle Wu to pay it. I will tell him in advance."
"yes."
Tang Ding looked around and couldn't see anything obvious. In other words, he saw it, but the machine was too complicated, and he couldn't understand the use of many parts.
"If the rails are made longer, can this thing really run?" Tang Ding thought for a few seconds and asked.
Han Du showed a smile on his face: "Of course, no
(This chapter is not finished, please turn the page.) Whether it is possible or not, Sun Xian and others will not know until they try it first. "
"Okay! When this thing is ready, you have to be the first to tell me." It was rare for Tang Ding to see something that made him inexplicably excited, so naturally he couldn't bear to let it go.
...
"The Duke of Zhen Guo bought land again, the Duke of Zhen Guo bought land again..."
"What? Is the Duke of Zhen going to buy land again?"
In the wine shop, a piece of news spread among the people of the capital at the speed of thunder.
"It's so pitiful, how many years has it been? I've finally been allowed to wait! By the way, where is the land that Zhen Guogong is buying?"
A young man who dreamed of getting rich overnight yelled with a red face.
Everyone else around the wine shop was drinking. No one answered the young man's question. They looked at him with a bit of contempt and disdain. They didn't want to talk about this person or talk to him.
However, some people still said carelessly: "Don't have dreams of getting rich. The land that Zhen Guo Gong wants to buy this time is thousands of miles away from your family. Besides, the land that Zhen Guo Gong buys this time is very small. , it’s only three feet wide. Even if I want to buy your family’s land, you won’t make much money.”
The young man was stunned and sat down with a disappointed face. He poured a bowl of wine into his mouth without saying a word.
Others ignored this person and turned to the person who had just spoken and asked: "Only three feet wide? How can you sell such a small amount of land? I'm afraid no one will be willing to sell it, right?"
"Why wouldn't you be willing?" The man took a sip of wine and said with a smile on his face: "Although the land is very scattered and divided into two points, the price publicly offered by the town is twice as high as the market price. In this way The price, let alone one or two cents, I am willing to sell it even if it is half a cent!"
"Yes, yes, it's much higher. Isn't this a free bargain?"
"The town government is still as arbitrary as ever. It buys land without bullying or asking, and even takes the initiative to double the increase. It is simply unheard of..."
In this world, wealthy families can never be offended by ordinary people.
Take the purchase and sale of land as an example. If a wealthy family buys it, the people will be very grateful if they can pay the market price. How can they expect more?
Even if it is a little lower than the market price, as long as they can get enough treasure money, the people can grit their teeth and endure it.
"But what did Duke Zhen Guo buy these lands for?" Some people couldn't help but wonder.
Han Do Shancai's reputation is exciting, and no one wants to know what he wants to do. As long as you can find out one or two things, you might be able to make a fortune from then on.
Isn't Chang Hao the best example?
He was originally just a storyteller in a wine shop, and he used to rely on rewards from people like them to make ends meet.
But ever since he got the news that he had reaped the benefits of Shibosi Securities, he has been out of control. Even now, he has no idea how rich his net worth is.
Some people say that he has a family fortune of millions, while others say that he is as rich as the country!
Just imagine, who doesn’t want to become rich overnight like Chang Hao?
"Stop guessing. If you could guess it easily, wouldn't everyone be like Chang Hao?" Someone sneered without the slightest politeness.
The person who was laughed at was not annoyed, but retorted: "Money and silk touch people's hearts! It took a long time to wait for such an opportunity. I don't believe you won't be tempted!"
No one will be unmoved, it’s just that everyone is self-aware. But if there is a real opportunity to make a fortune, no one would be willing to give it up.
Therefore, everyone no longer laughed at this person, because they were the same as this person.
...
The entrance of the academy.
A young man had a baggage hanging on his shoulders and his temples were a little messy. It looked like he had experienced a lot of travel.
The servant saw that this person was not wearing the green shirt of the academy. In addition, all the academy students were studying in the academy. It was obvious that this person was not a student of the academy.
I saw him standing at the gate of the academy, looking up at the plaque of the academy and unwilling to leave for a long time.
The handyman stepped forward, bent down and handed over his hands with a smile on his face: "Is this young master here to find someone?"
The young man glanced sideways at the handyman, grinning with a warm smile: "I'm here to become a disciple."
Apprenticeship?
Over the years, the handyman has seen countless people who want to come to the academy to become apprentices, and most of them are young people.
He was very experienced in dealing with such a young handyman. He was not annoyed at all, but nodded with a smile: "Young master wants to come to the academy to study. Of course, the academy welcomes it. But now is not the time for the academy to recruit students. Please come back then, Master!"
If it had been in the past, after the handyman said these words, no matter who he was, he would have wisely retreated.
After all, the academy is now an important place in the Ming Dynasty. Even the young masters in the duke's mansion would not dare to act recklessly here!
But this young man didn't.
He looked sideways at the wooden board beside him. This wooden board was exactly the one on which Han Jingyun's twenty-tree number solution was painted.
The small wooden board has stood here for so many years, but it is still like Mount Tai, weighing down the people of the Ming Dynasty who pride themselves on being talented people.
"What does he want to do? Does he want to challenge Master Han?" Seeing this man walking up to the board, the handyman couldn't help but think.
Although Mr. Han is now the queen, people in the academy still like to call her the principal.
Lord of several courtyards!
As long as no one surpasses her in mathematics, she will always be the master of mathematics in the academy!
Slightly surprised, the handyman then shook his head secretly, "If you want to challenge Dean Han, you are simply overestimating your capabilities!"
Every year, more people come to the entrance of the academy to challenge this question than those who come to study, but after so many years, this question is still quietly placed here.
The handyman didn't think that a young person could solve this problem.
After the young man read the question, his eyes gradually solidified.
The handyman knew that he was caught up in Tao's inner calculations, so he just stood aside and waited quietly without urging.
It even meant to protect him and avoid being disturbed by other people.
"Look! Someone is coming to challenge the twenty trees at the entrance of the academy!"
In the wine shop across the street, someone immediately exclaimed.
But when the man looked back, he found that no one else in the wine shop was motionless. Instead, they were all looking at him with smiles on their faces.
The owner of the wine shop even touched his chin and said with a smile, "This guest doesn't come here very often, does he?"
Without waiting for the other party to answer, the owner of the wine shop continued to explain: "There are people who want to come to the academy to challenge this question almost every three to five days. There is nothing new. If you come here more often, you will naturally know this."
The person who just exclaimed suddenly laughed awkwardly. He also felt that he had indeed made a fuss just now, so he sat down slowly and embarrassedly.
Instead, the other guests in the wine shop began to talk around the young man at the entrance of the academy.
"You haven't given up after such a long time. You seem to be a perseverant young man!"
"Why don't you think he can come up with more solutions?"
"Can he solve it? He is still so young, how is it possible?"
"How is it impossible? Wasn't the Queen very young when she was rescued?"
"Hahaha, who is the empress? She is the goddess of the Ming Dynasty, the pinnacle of wisdom. How can anyone be able to compare with her?"
...
