'Owner, in which direction are you going to go for this sea trial?' Please also advise. Pen? Interesting? Pavilion wWw. ｂiquge。 Info' Captain Xin asked respectfully, 'Thou art the bow, and thou shalt decide. That's true, but the bow of Xin didn't act arbitrarily.

If you have a decision, go north along the coast for a day, and then turn back. '''To the north?'' Aren't you afraid of running aground? ''Not really.'' Captain Xin shook his head, "In the past, there were sand boats to the north, and the northern coast was shallow, so it was easy to run aground. The flat bottom is easy to use. ’

But though the ship was pointed, it did not carry much cargo, except for a little food and water, and it was ballast. Don't be afraid to be careful. ’

Li Chen pinched his chin and thought for a while, "How about going northeast, the direction is just right, you can test the no-load speed of the ship." Although Captain Xin said that he was not afraid, Li Chen still felt that he could avoid it.

'To the northeast. The bow of the ship Xin was a little embarrassed, but he immediately made up his mind, "Okay, let the owner take a look, I have worked hard." ', Unique? Li Chen's curiosity was aroused.

Xin Chuantou, hardworking, is a veteran, Li Chen will hire him, in addition to being a veteran, there is also that he is quite famous. Once, he led a ship, because of a storm lost, in the end, he still led the ship to find the other party's portrait and return safely. This time he made a name for himself and became a famous shipwreck.

And Li Chen was able to hire him because he was in desperate need of money, but his original owner, the old owner left, and the young owner was stingy and stingy, refusing to lend him money, and there were many derogatories, and even thought that he was not worthy of his name and wanted to deduct his income.

In a fit of anger, he broke away from the original owner, and Li Chen was able to hire people with a lot of money. Now hearing him say that he has a unique skill, Li Chen is very curious at the moment.

After a while, I saw the bow of Xin, and the gods had to take the plate out secretly, and Li Chen looked at it curiously. I saw that this plate was shallow, with water in it and a piece of iron floating on it. It turned out to be just Sinan, and he was disappointed at the moment.

Si Nan, Li Chen certainly knows this kind of thing, one of the four great inventions of the Chinese. It is recorded that it appeared in the Song Dynasty, and it was originally used in the Tang Dynasty, but it was only in the Song Dynasty that the sea trade was developed, and this technology was widely spread, so it was recorded in history.

Li Chen was disappointed in his heart, but his expression was flat, based on etiquette, he did not show his disappointment, which was very hurtful. It's just that Ship Xin misunderstood, thinking that Li Chen didn't know about it.

It's a strange thing, and I got it by accident in my early years. 'Captain Sim recounts how he got the oddity. It turned out that he traveled south and north in his early years and worked as a ranger. He made a sword in a blacksmith's shop, and when he returned home, he sharpened it and made some iron filings. As a result, a relatively large iron shavings fell into his wine bowl.

Haha, at that time, I was really bored, and I kept fiddling with the iron piece, but I found that no matter how the iron piece was pulled, it would return to its original position, which was why I had to work hard as the head of the ship. ’

Li Chen nodded in agreement, and praised a few words, this Xin bow seems to be really precious this thing, very proud, it is rare for him to say so many words.

For this phenomenon, Li Chen thought about it, knowing that it was a weak magnetization effect, and thought that the iron piece was hammered by high temperature and cooled down rapidly. Due to fate, he was discovered by the bow of Xin, which led him to get lost, but he was able to lead the crew back to Datang.

However, Li Chen took Sinan and watched carefully, but he was even more disappointed in his heart. The Chinese, at least since the Song Dynasty, have been using Sinan on a large scale, and it has been applied to navigation on a large scale, but no one has modified it. From the Song Dynasty to the Ming Dynasty, hundreds of years have passed, and it has always been like this.

The great thing is to change the shape and make it into the shape of a fish, or a bucket spoon. But no one thought to give him a more precise direction, which could distinguish the south, east, and northwest. It seems that all you need to know is the general direction.

No one thought that this Sinan should be carefully designed, not only in the south, south, west, and northwest, but even the angle is clearly marked.

However, Li Chen thought about it, and he couldn't blame the Chinese at that time. The first is that the Chinese do not need to cross the ocean like the Westerners. Congguang. Starting from the state, all the way to Tianfang, you can walk along the land and the coastline halfway, and never get lost.

Li Chen heard what Captain Xin said. From the state to the sky, the journey takes about 60 days. If you are serious about direct flights, it will not be practical for that long. However, this part of the voyage basically stops at the port every few days.

That's how everybody runs, and the route is fixed. In other words, it would be nice to have a general direction. So you don't need to have such a delicate compass, just know the south, and the other directions are fixed there, and then you can probably go with experience.

'Show you something good. Li Chen returned Sinan to the bow of Ship Xin, and decided to repay Li by letting him see his secret weapon.

He walked back to the children, who were still looking at the sea with great interest, pointing and laughing from time to time. There are only two people who are different, one is Huang Tiansheng, and the other is Yixin. They have something in their hands and don't know what they're doing.

'One heart, Lao Huang. Li Chen walked over and beckoned them, "Busy." What's the matter? Huang Tiansheng said angrily, but he ignored him, and both of them were busy writing their own things.

Both of them were busy in their hands, looking at it in their eyes, Huang Tiansheng was holding a strange object with a tube, and he was also looking through the tube, but he had a tripod.

'Wait, give your treasure to the bow of Xin. When the time comes, you'll need the help of the bow of the ship. ''What is this?' Xin Xin took the three strange items in his hand and turned left and right.

'That's it. ''What is this?'' Li Chen first handed him a tube, demonstrated the usage to him, took it and used it diligently, and found that the thing in front of him suddenly became very large, and then he turned to other places and found that he could see far away. This is the telescope.

'Wonderful, good. The front is a comment, the back is a compliment, as a captain of the ship, he can see the use of this thing at once, and he can't put it down.

'That's for you, look at this again.' Li Chen then put two pieces that were also telescopes, but with strange matches. I don't know how to use it, if it's a telescope, I don't need to do it so much, I can only look at Li Chen in doubt.

'Show it to the bow of the ship. Li Chen patted Yixin, took the telescope with a tripod and demonstrated it. This is a theodolite. He also asked Huang Tiansheng to demonstrate, "This is a sextant." ’

If you have played the Age of Discovery, you know that this is the Age of Discovery, and it is a prop used to locate your own position. The principle is very simple, that is, to use the triangular status method to determine one's own orientation. It is indispensable for long-distance voyages. Without such a thing, do you want to cross the Atlantic?

Okay, too. Anyway, as long as you go out of the Mediterranean, like going west, it is absolutely impossible to miss the Americas. However, if you go like this, there is no guarantee where you will go. If you just want to reach the Americas, you can drive it casually, but if you want to get to that port accurately, you can't do both.

That's what the kid discovered. After introducing the sextant, Li Chen pointed proudly. On the way from Xufu to Yangzhou, I was stargazing. Maybe outsiders just look stupid and don't even understand worry.

But he focused on doing things, but he found that the stars here were different from those of Xufu. After that, he continued to advance to Yangzhou, and he was observing all the way. In the end, when Huang Tiansheng joined Li Chen's teaching team, he hit it off with Yixin, and the two went stargazing all the way from Yangzhou to Guangzhou, just to measure this.

'Not bad. Concisely and diligently, give this comment. However, Li Chen could hear that he was perfunctory, and probably felt that it would be good to sail according to his experience, and with a Sinan, he would definitely not get lost.

Seeing this, Li Chen didn't say much.

According to his hard work, he couldn't understand how important it was to be able to locate where he was, and he didn't want to talk about it, so he said lightly, "On the way, the two of them need to measure a lot of things, and I ask Captain Xin to cooperate more." After saying that, he went back to the children and asked the two of them to discuss with the bow of Xin how to cooperate.

When he returned, he walked around and found that the children were hiding in the shade, as if they had been killed. It turned out that as the ship entered the deep sea, the waves were getting bigger and bigger, and he was seasick, Li Chen laughed secretly in his heart, now he knows that sailing is not fun.

When they first went out to sea, a group of children still felt very fresh, watching the sailors raise their sails, watching them adjust the sails, watching them clean the deck, watching the fish leap out of the water from time to time, and it was like a blue carpet

The sea, Golgoth, makes them very fresh. But the boat got more and more bumpy, and many people began to get seasick.

In addition, the children have been gradually scorched up by the sun, and the sun shines uncomfortably. So I found a shady place, avoiding the sun, and observing the ocean.

'Is it good-looking?' It's a pity that I didn't have a chance to take you to the grassland. But you can imagine that the white spray is like a hill. The blue part is like a grassland, and we are riding on a big horse, galloping across the endless grassland. ’

Li Chen saw that they were listless, so he began to talk about the grassland, describing the sea as a grassland, and making them imagine that they were on the grassland, and at this time the sun gradually deflected and the sun set.

'It's beautiful. ''It's beautiful. Seeing the orange color, as if a big chicken is going to set the sun, the children raised their interest again, admired, and expressed their feelings, Li Chen was also fascinated to look at the sunset, this kind of beauty, he actually did not see it. I saw a big ball with a red notice, slowly falling into the horizon, reflecting an ocean of red.

It's like a big pancake, I really want to eat it. ', it's the fat ball... There are people everywhere, but rest assured, he won't really eat the sun. It's just that his scephaly behavior was unanimously criticized by everyone.

However, the criticism didn't last long, starting with the fat ball, the children grunted one by one, and then a group of people suddenly burst into laughter, Li Chen compared his hands, and a group of locusts went to plague the restaurant. (To be continued.) )
