    Chapter 263 The Impractical Sextant

    "Hey, third brother, don't be afraid. This thing is a machine developed by Dean Zhao. You only need to add water and coal into it, and the machine can run and generate huge power. This kind of machine is called  We call it a steam engine, and this kind of train is just an application of the steam engine." Li Min said, introducing Zhao Yifan beside him to Li Ke and others.  Although Yifan is just a girl, she is the dean of the Dengzhou Academy of Sciences. In Li Min's eyes, she is more important than the entire Dengzhou City.

    After hearing this, the three brothers Li Ke were very surprised. They turned to look at the roaring steam locomotive, and then looked at the petite Yifan. They really couldn't believe that the big man was made by this girl.

    Speaking of which, the speed of this train is really slow. I saw the train rushing out of the woods just now, but I waited for a long time before the rumbling train reached Li Min and the others.  However, the train did not stop. Instead, it turned directly over them and then stopped.

    "Third brother, seventh brother, and eighth brother, how about we go up and take a ride together?" Li Min invited with a smile. This train has been running for many days, and there has never been any major problem. In addition,  The speed is slow and there shouldn't be any danger, so Li Min wants to try it out for himself.

    "Then what are you waiting for? I'll go first!" Li Zhen had been impatient for a long time. As soon as she heard Li Min's words, she immediately rushed up first.  Because they knew that Li Min and the others were going to take the train, no one else took the train today. When Li Min got on the carriage, he found that the layout of the carriage was very similar to that of buses in later generations. Rows of wooden stools were fixed in the car.  Although it looks a bit crude, it can accommodate more people.

    The four of them, Li Min, were the first to board the car and each found a seat by the window. They were accompanied by Lu Hong and Zhao Fu's father and daughter. Originally, Li Min wanted to invite Yang Xun and Cai'er to come too, but he thought about it.  Due to Yang Xian's condition, he couldn't be too stimulated, so he didn't invite him. Although Cai'er was very interested, she knew her father couldn't go, so she stayed in the city to accompany him.

    After everyone sat down, with a whistle, the train finally started slowly.  Li Min was accustomed to riding in various motor vehicles in his previous life, so naturally he didn't feel anything.  However, Li Ke and Li Zhen felt very novel and excited as the train slowly accelerated. They even came to ask Li Min about the working principle of the steam engine. After all, in their opinion, it was possible to steam the steam engine without manpower or animal power, just by drinking water.  The machine that uses water to eat coal and runs is really amazing!

    Although Li Min didn't know much about machinery, it was enough to fool Li Ke and the others, so he talked about the working principle of the steam engine and the difficulties he encountered when he asked Yifan to design and manufacture the steam engine.  Apart from Li Min and Yifan, not even Zhao Fu knew much about it, so everyone looked very relaxed while listening to Li Min talk about the history of the development of steam engines while admiring the scenery outside the car window.

    However, while the train was traveling towards the port, Li Min discovered an extremely interesting phenomenon. For example, when the train was moving forward at full speed, several people would suddenly run over on the concrete avenue parallel to the railroad tracks and quickly catch up with the train.  He grabbed the carriage door and tried to get in, but was driven out by the royal guards at the door.

    Seeing this situation, Li Min burst out laughing. Yifan had just said that this train usually runs between Dengzhou and the port, and it is free for people to ride. It is estimated that these people are taking a ride as usual.  After all, although the speed of the train is slow, it is at least a little faster than walking, and it can also save some energy.

    But when Yifan saw this situation, his face turned slightly red. As the main designer of trains, the speed of trains is only slightly faster than walking, let alone competing with carriages. The only comparison is  The advantage of the carriage is that as long as the train does not break down and has enough fuel and water, it can run forever.

    After taking the train back and forth between Dengzhou and the port, Li Min praised Yifan greatly and encouraged him to keep up his efforts and strive to increase the speed of the train. In addition, he was impressed by Yifan's plan to build a steam engine ship.  Li Min immediately approved it, and also proposed that it could be modified on the basis of cars and ships. Firstly, cars and ships were more suitable to be powered by steam engines. Secondly, Datang's cars and ships were relatively small and relatively simple to modify.

    Yifan carefully wrote down all Li Min's suggestions, and also discussed some detailed issues with Li Min. Although Li Min couldn't help in any specific way, he could provide some novel ideas and steam engines.  The future development direction of the ship, and these are exactly what Yifan needs.

    "Your Majesty, Mr. Wei, is here to see Your Highness!" In the main hall of Prince Qi's Mansion in Dengzhou City, Wei Heizi, who was in charge of the Dengzhou Ship Design Institute, saluted Li Min with a respectful expression.  In addition to the two of them in the palace, Zhao Fu is also here.There were seven or eight young people standing in opposite positions.

    "Dean Wei, there is no need to be polite!" Li Min said with a smile.  Since Wei Gong became the dean of the Ship Design Institute, he has become a leading figure in the shipbuilding industry in Dengzhou. No one dares to call Wei Heizi by his nickname anymore. Although Li Min likes to call Wei Gong by his name,  In front of outsiders, he still refers to his position.

    "Thank you, Your Highness!" Wei Gong stood up after hearing this. At the same time, he looked at the seven or eight young people next to him suspiciously, guessing their origins.

    "Dean Wei, I have invited you and Zhao Biejia here at the same time. The first thing is to introduce these new colleagues to you." Li Min said, pointing to the seven or eight young people next to him and said, "These few  They are all disciples of Taishi Ling Li Chunfeng, the leader is named Xie Chun, and this one is named Hua Guang"

    Li Min introduced these seven or eight young people. After Li Chunfeng successfully developed the sextant, he sent disciples like Xie Chun to Li Min and asked them to follow Li Min to Dengzhou, mainly to teach them how to use the sextant.  The method is taught. As for how to teach it, that is Li Min's problem.

    However, when Li Min came to Dengzhou last time, Xie Chun and others did not stay, but followed him to Taiwan. The main reason for this was to use a sextant to measure the longitude and latitude of the major ports along the coast and do it one by one.  Even when Li Min was in Taiwan, people like Xie Chun took a boat to continue southward and continued surveying in the Guangzhou area. They surveyed almost all important seaports. These data are very useful. I will teach sextant in the future.  When explaining how to use it, these data will also be included in the teaching materials.

    After introducing the person, and then both parties greeted each other, Li Min continued: "When Li Taishi came to Dengzhou, I asked him to help design an instrument. This instrument is used for positioning at sea. It can be said that  As long as we have this kind of instrument, we almost don¡¯t have to worry about getting lost at sea!¡±

    "Sea positioning instrument! Your Highness, there is such a sharp weapon in this world?" As soon as Li Min finished speaking, Zhao Fu and Wei Gong were shocked.  One of them is a master shipbuilder, and the other has been an official at the seaside for many years. They naturally know the seriousness of getting lost at sea, but they did not expect that they can actually solve the problem of positioning instruments at sea?

    "Haha, you two adults should not be surprised. I heard from the teacher that this kind of sextant was proposed by His Highness, and then the teacher and others painstakingly developed it for more than a year and spent countless efforts to create it. After our testing,  The positioning effect of the sextant is excellent. Although there may be certain errors, it is within the acceptable range!" Xie Chun, the leader, said with a warm smile.

    Among Li Chunfeng¡¯s disciples, Xie Chun is the oldest one, and he is also highly talented and has learned the most skills from Li Chunfeng, so he is usually the leader.

    "Sextant? What a magical thing!" When Wei Heizi heard that His Highness King Qi proposed it, his eyes immediately lit up and he no longer had any doubts in his heart.  When he was still in Chang'an, Li Min asked him to help make two ship models, and these were the Galen ship and the Fu ship, so he had always admired Li Min's ability.

    "Your Highness has such a magical instrument, can I let my subordinates take a look first?" Zhao Fu also knew that Li Min knew Yuan Bo, but he was very curious about the sextant and wanted to see what magic this thing had?

    "This is easy. Xie Chun, you should carry it with you. Show it to Zhao Biejia and teach him how to use it!" Li Min said with a smile.

    "Yes!" Upon hearing this, Xie Chun immediately took out a palm-sized sextant from his arms, and then walked over to let Zhao Fu and Wei Gong take a closer look. At the same time, he also explained the principle and usage of the sextant.

    When Zhao Fu and Wei Gong saw the fan-shaped sextant, they found that the shape was a bit complicated. When they heard the series of professional terms spoken by Xie Chun, they were both dumbfounded because they didn't understand it at all.  Among them, Wei Gong was the only one. He was originally a craftsman, and he knew a little bit about arithmetic, but he was much worse at astronomy and the like.  Zhao Fu was born in the imperial examination and was involved in arithmetic and astronomy. Otherwise, he would not have given birth to a daughter as smart as Fan. But even so, he could only understand 40 to 50% of the words. This made Zhao Fu's  The old face is a bit unbearable.

    Seeing the shameful look on Zhao Fu's face, Li Min secretly smiled in his heart. In fact, the use of the sextant is not difficult. Zhao Fu can learn it quickly with his basic skills, but he does not understand some basic concepts.  For example, the concepts of longitude and latitude, etc. If he didn't understand these, he would naturally not understand what Xie Chun was talking about.

    Although he only understood 40 to 50% of the meaning, Zhao Fu also understood the importance of the sextant. However, this also reminded him of a question, so he bowed to Li Min and said, "Your Highness, this sextant is good."  That's good, but if you want to operate it, you need the other party to know astronomy and arithmetic, but in my opinionFor example, there are tens of thousands of registered ship owners, but only one in a thousand has the basic skills to use a sextant. So is this thing too impractical?  "
