Datang Nongwang

Chapter 655 Sextant

After another seven days.

Chen Juan and the others had been waiting outside for a long time. They were standing outside the door of Li Chongyuan's wooden house. While waiting anxiously, the door of the wooden house finally opened.

Chen Huan directly pushed Li Chongyuan away, and said loudly: "Chongyuan, you have kept us waiting for more than half a month, what do you want to give us, show us quickly."

"Yuan'er, I see that you have been shutting yourself in the house these days, what are you doing?" Chen Juan was also puzzled.

Indeed.

It has been half a month since Li Chongyuan told them to wait a few days before setting off.

For half a month, Chen Juan and the others really panicked after waiting.

Originally, they were going to go to sea again the day after they returned to Xisha Island. If Li Chongyuanqiang hadn't left them behind, they would have already reached the southern part of the East China Sea.

But now after half a month, Li Chongyuan finally opened the door of the house, and the most urgent ones are none other than them.

in this period.

Li Chongyuan even ate and drank in the wooden house, he would come out except for going to the toilet, and he would basically be busy with his own affairs in the wooden house at other times.

And when Chen Juan and the others occasionally asked a question, Li Chongyuan always threw it to the other party, just wait and see.

Ok.

It's time to wait and see.

When Chen Huan entered the room, the first thing he saw was a nondescript thing on the desk in Li Chongyuan's work room, "Chongyuan, the thing you said to prepare earlier, can't it be this broken thing? I don't see anything wrong with it. Special."

Li Chongyuan hurriedly led Chen Juan into the wooden house.

At this time, what Chen Juan saw was not the desk, but a huge map hanging on the wall. She approached it curiously, and looked at the map on the wall with her almond eyes wide open.

"Aunt Huan, don't underestimate this thing. Although I made it a little rough, I can tell you that this thing is much easier to use than the compass you are using now." Li Chongyuan saw Chen Huan stretching his hand towards it. The sextant on the desk went away, quickly stopped it, and held it in his hands.

Chen Huan, on the other hand, had an unhappy expression on his face, and snatched it away, "Why, are you afraid that I will break your baby? It doesn't look like anything special to me, and it's not right. There are crystals and colored glazes. It’s worth some money. You said that this thing can replace the compass, but you don’t mean to say that this thing can point the direction. But I haven’t seen the direction needle yet?”

wipe.

Worth some money.

Well, for the uninitiated, the sextant is indeed worth some money. After all, there are crystals and precious things like colored glaze.

When Li Chongyuan saw Chen Huan playing with the sextant he had finally made, he was really afraid that she would accidentally drop it on the ground.

If he really wanted to do this, Li Chongyuan would really want to cry without tears.

"Aunt Huan, you should be careful. This thing is not only valuable, but also more accurate than the compass. Don't underestimate this thing. It took me a lot of brains to make it. If it breaks , I have to spend a lot of brains to make it." Li Chongyuan was really worried when he saw Chen Huan throwing the sextant around.

You can't say it, you can't scold it, and you can't control it.

This is Li Chongyuan's current situation.

Fortunately, at this time, Chen Juan transferred from the map to the sextant, and took it from Chen Huan's hand, and she was very careful, so Li Chongyuan felt relieved.

Chen Juan looked at it for a while and asked: "Yuan'er, you said this thing can replace the compass to indicate the direction, why is it so different from the compass?"

"Aunt Juan, Aunt Huan, this is called a sextant, and it is made of one-sixth of a circle. On the vast sea, if you want to indicate the direction accurately, you need not only a sextant, but also a These things are for auxiliary use. Aunt Juan, you can arrange a few people to come over to learn later, and I will teach them how to use this thing and how to find directions accurately." Li Chongyuan quickly pointed to the map and other things on the desk and explained.

sextant.

When Li Chongyuan was studying in his previous life, his teacher had mentioned it.

Although not specific, when I was taking the course of marine ichthyology, the teacher specially introduced the sextant.

Moreover, there happened to be a sextant in the school's laboratory.

Therefore, Li Chongyuan also knows the general principle of the sextant.

but.

If you want to use a sextant to determine your specific position and direction on the sea, you have to use a map and other auxiliary things.

For example, a compass, a pen, a map marked with latitude and longitude, or a formula.

The most important thing is that it still needs to be in the sun.

If there is no sun, everything is useless.

When Chen Juan and Chen Huan listened to what Li Chongyuan explained, they felt as if they were listening to a heavenly scripture.

Three words, I don't understand.

but.

Li Chongyuan was a bit patient when he arrived. He pointed to the map hanging on the wall and said, "Chen Juan, Aunt Huan, look at this map. This is a map I drew about the sea area near Tang. Don't ask me first." How can I draw a map. This map is marked with north, south, east and west, and meridians."

As Li Chongyuan began to explain in depth.

The two also slowly learned about the earth.

I even know how to use the map and the sextant.

When the two understood the importance of the sextant, they directly asked a dozen people to come and learn.

From morning to evening.

at last.

Li Chongyuan was finally relieved.

In order to explain the use of the sextant, Li Chongyuan spent a lot of brains.

even.

Li Chongyuan also deliberately listed all the formulas and data, so that Chen Juan and other people in Qingfengzhai would know how to use the sextant.

Of course, Li Chongyuan took a lot of effort to explain how to read and identify the map.

Also.

As for the map used at the moment, besides mountains, there are waters, and then there are cities. The drawing is so simple that Li Chongyuan has a headache when he looks at it.

And the map drawn by Li Chongyuan was from his previous life, and the markings were extremely accurate.

Where is the coast, where is the river estuary, where is the island and so on.

Even the approximate latitude and longitude lines are marked on the map.

Li Chongyuan couldn't mark out the specific latitude and longitude, but he marked it roughly.

After all, a sextant needs to be identified with a map. Even if you have a sextant, if you don’t have a map, it’s not as easy as using a compass.

Fortunately, the dozen or so people Chen Juan and the others found were all literate and had learned arithmetic, otherwise, it would be useless.

During the process of learning, everyone also exclaimed, saying that Li Chongyuan is the living star of Wenqu, who knows astronomy and geography.

After the study, Chen Juan and the two even caught Li Chongyuan who was about to escape, and asked who taught him about maps and sextants.

"Aunt Juan, Aunt Huan, don't ask any more questions. Even if you ask me to death, I can't say it. I promised them and swore that I can't talk about it. As long as I say it, They will die suddenly." Li Chongyuan was really helpless after being questioned.

In the end, when they heard what Li Chongyuan said, they had no choice but to give up on the questioning.

However, the way the two looked at Li Chongyuan was like looking at God.

Fortunately, it was getting late, and after Li Chongyuan found an excuse to go to eat, he locked himself up and fell asleep.

It wasn't until the next day, when Chen Juan and the others were about to board the boat and go to sea, that Li Chongyuan finally got rid of this look.

Li Chongyuan, who was standing at the pier, looked at the two girls in front of him, "Aunt Juan, Aunt Huan, you must be careful, don't go to rob pirates again. This trip to sea is to verify the map and sextant. And , if there are any mistakes in the marking on the map, please mark it more, and I will correct it when I come back."

"Chongyuan, you've been talking for a long time. We've listened to it eight hundred times. It's okay, it's okay, let's go." Chen Huan couldn't stand Li Chongyuan's nagging, and went directly to the boat.

But Chen Juan gently hugged Li Chongyuan, smiled, and gently helped Li Chongyuan to stroke the hair on his cheeks, "Yuan Er, don't worry, we know what to do, you said it all Many times."

The fleet leaves the dock.

Li Chongyuan stood on the pier, looking at the leaving shadows of the five seniors and the second junior, feeling a little depressed.

After getting along for a long time, Li Chongyuan can feel the two people's concern for him all the time.

This go.

Li Chongyuan felt as if he had lost something again, which may have really confirmed what Chen Juan said, I am your aunt, and we are related by blood.

Li Chongyuan, who was depressed, recovered after two days.

Paracel Island has too many things to be busy with.

and.

Li Chongyuan also asked Chen Juan and the others to draw a map of the world while they were out at sea.

too busy.

In addition to drawing a world map, he also needs to keep an eye on the progress of the shipyard and the landfill on Xisha Island. Li Chongyuan has no extra time to think about other things.

After entering April.

Outside Xisha Island, more and more cargo ships began to appear.

When those cargo ships passed Xisha Island, they were very curious, and some even docked at the pier, wanting to board the ship to inquire.

but.

It is impossible for these cargo ships or ships to dock at the dock.

As long as there are ships wanting to dock at the pier, Xingba and others will take people away and will not allow any ships that are not from Xisha Island or hired by Xisha Island to dock.

Xisha Island belonged to Li Chongyuan, and it was approved by Emperor Li Shimin.

In order to occupy Xisha Island, Li Chongyuan even went to Changshu County to file a case, and even went to the Suzhou government office to file a case.

It is a private territory, and it is Li Chongyuan who wants to spend countless sums of money to bury Xisha Island, which has created a big island. Not everyone can come up to it.

Moreover.

Li Chongyuan didn't want anyone to come in and explore the secrets of the shipyard.

although.

The shipyard does not have any big secrets, but it is about the construction of large ships, and Li Chongyuan does not want anyone with a heart to come and steal his blueprints.

Just in case, Li Chongyuan extended the dock to the island for half a mile, and even asked someone to set up a shut-off valve.

It goes without saying that Li Chongyuan did this to prevent anyone from diving into the dock, and then entering the dock through the dock to explore the secrets.

Li Chongyuan has done so much and defended so much, but he still got the news from some caring people.

This is not.

The Qi family in Jimo received news about Li Chong's Yuanming ship.

but.

The news about the paddle steamer received by the Qi family was not about Xisha Island, but about the paddle steamer that Li Shimin had taken from Li Chongyuan.

"Da Lang, this is a letter from your second uncle from Chang'an, please read it." Qi Wu, the head of the Qi family, received a letter from his second brother from Chang'an, inviting his eldest son.

Qi Wu is the head of the Qi family.

The Qi family lived in Jimo for generations and used shipbuilding as their business.

Moreover, the Qi family is a big family in Jimo, and at the same time has a close relationship with the Kong family, and its daughter married the heir of the Kong family as a concubine.

Qi Jia Dalang, named Qi Feng.

Qi Feng was exactly the Qi Family Dalang who wanted to chase Li Chongyuan's boat when he passed by Jimo when Li Chongyuan returned to Chang'an last time.

Qi Feng took the message from his father: "Father, is there anything Second Uncle needs us to do?"

"It's nothing, but I found an errand for your third brother, and I want your third brother to go to Chang'an. In addition, your second uncle mentioned a ship in the letter." Qi Wu said casually , then waved to Qi Feng.

Qi Feng didn't ask any more questions, and got his father's instructions, and quickly retreated out.

After Qi Feng read the letter, he was greatly moved, but he was still surprised, "Could it be that the ship I saw last year belonged to the Li family? Impossible. Most of the ships in the imperial court were not given to my Qi family. Is it here to make it? Does that person not believe in my Qi family?"

Qi Feng was suspicious, and then went back to see his father, and raised the question in his heart to Qi Wu.

After Qi Wu heard about his son's suspicion, he was also a little surprised.

"This kind of thing you said should be impossible. Your second uncle said in the letter that the boat was donated by the people of the Li clan. If the person wants to replace my Qi family with the Li clan, I'm afraid it's not a gift." The boat is so simple, but it’s normal for you to have doubts. In this way, since your second uncle finds a job for your third brother in Chang’an, then let your third brother go to Chang’an to have a look.” Qi Wu thought for a long time Said.

But Qi Feng had some disagreements, "Father, you also know that the second uncle has long wanted us to stop building ships and turn into an official career. And the third brother also complemented the second uncle's opinion, such as asking the third brother to investigate the situation , I'm afraid I won't get accurate information. Why don't I go to Chang'an with my third brother this time, and I happen to have a guide on the way."

Qi Wu nodded.

After a few days.

The Qi family brothers left Jimo for Chang'an.

But Li Chongyuan, who was far away on Xisha Island, didn't know it, because the matter of his dedication of the boat was taken into consideration by someone with a heart.

but.

Even if someone misses Li Chongyuan's ship, if there is no strong means, it may be impossible to win it from Li Chongyuan.

Li Chongyuan was still busy with his own affairs, and didn't have much thought to pay attention to these things.

He was needed to draw the world map, and Li Chongyuan's opinion was also needed for the shipyard to build Type B paddle ships.

In short.

At this moment, Li Chongyuan didn't have any spare time at all, he wished that he could have the technique of splitting himself and divide himself into ten people to do things.
