The traditional Chinese needle navigation chart is very complex, and generally it must state the destination, direction, voyage, and arrival location.

There are many professional terms in it, such as elixir, sewing needle, flat, picking, seeing, collecting... and also measuring and recording water depth during the voyage, which is also a type of needle data.

If no one teaches you, you can read the needle roadmap and various parameters by yourself. It would be strange if you are not confused!

In fact, many people do this to instinctively encrypt their knowledge and create obstacles for later generations.

For example, the so-called "dan needle" is confusing to see the term just by looking at it. In fact, it means "single needle", which refers to a one-way heading and that's all!

Xiao Heng has actually seen a lot of such things. For example, the ratio of "one, two, three (harmonious)" in the black gunpowder formula is just a guess for those who don't know the profession. Those who really understand the profession know that some of the "one, two, three" are pounds and some are 2.

In addition, Xiao Heng also learned from Wang Tiechhui that there are many inconspicuous terms in the blacksmith shop, but to put it bluntly, it is just some experiences such as quenching and backfire, temperature and flame color! What is foggy is that people are afraid of understanding.

There are more metaphors in this aspect of boxing and foot skills. What is the energy sinking into the Dantian and the Ren and Du meridians can be explained clearly in just one sentence. But they are so mysterious that it makes people unable to understand it, so that the light skills of "stepping on the right foot" are really nonsense!

Xiao Heng had asked Han Ziqing about martial arts, internal strength and other things before. After asking, Han Ziqing looked at Xiao Heng and laughed wildly... Finally, he explained to Xiao Heng what a powerful martial arts meant—

——High strength, quick reaction, accurate fight, and steady stand!

That's right, it's that simple! Otherwise? Could it be that the master's "Five Lightning Whip"? What kind of thing is that thing? Just open the video and check it out.

The same is true for the needle road map. It is based on observing the characteristics of the coastal terrain and measuring local hydrological data, and using a compass to determine the course... The so-called needle road is so simple.

Complex simple things and try to make others confused. Complex national affairs are often as simple as possible to make decisions based on personal interests and likes and dislikes, or is this the reason why the feudal empire cannot last long?

Xiao Heng was a little disgusted with this bad habit of cherishing himself, but they have always lived like this. Changing customs and customs is not achieved by talking or just one command. This is a very long process.

...

On the small pier not far from the west of Qin Mansion, a beautiful white sailboat slowly sailed.

A porter who was resisting the bag suddenly stopped and looked at the white sailboat that was driving up from the downstream and murmured: "Hey, look! That boat is so white!"

"Baibai? Are you confused? The boat and your wife Nako-hai?" Another porter was about to speak royally, and when he looked up, he saw the snow-white sailboat.

"It's so pretty..." the royal porter murmured, "Hey, this boat must not be more valuable than a pleasure boat?"

"The one who is valuable in the pleasure boat is not the boat, but the girls on the boat." The porter had also turned on the imperial accent.

"It's true!"

"Hehehehe..."

The two old pornographic critics looked at each other and tried hard to carry the bag, and seemed to be more motivated.

In fact, not only the workers on the dock were talking, but also the pedestrians on the street, sailors on the canal boat and diners in the restaurant were all watching the beautiful sailboat slowly docking.

Xiao Heng ignored the discussion around him and just stood quietly on the dock waiting for the ship to dock.

This white sailboat is the technical verification ship "Big Touchi".

Since the Tuberite draught is deeper than that of ordinary canal ships, it is impossible to directly dock like ordinary canal ships and then build wooden boards up and down. So Xiao Heng, who had long considered this issue, discussed with the person in charge of the dock and built a short trestle next to the dock.

Although the pier is short, it is enough for the Toucan. After all, its draft is just a little deeper than the canal boat.

After the sailing boat was parked and the wooden frame was on, Xiao Heng went up to meet him.

"Captain Guan... Thank you for your hard work." Xiao Heng took a step forward and took the initiative to hold Guan Lin's hand and said.

"It's not hard, to be honest... it's a pleasure to ride on this boat to the sea." Guan Lin also replied with a smile.

The two of them were polite, and Xiao Heng took the entire ship's team back to Qin Mansion in a mighty manner.

The Toutobird's voyage was from Lin'an Prefecture, first traveling eastward and then heading southward, and using the traditional needle road map to Fujian. After a brief rest in Fujian, he continued to go south to Taiwan, the southern end of Luzon, and then circled east along the coast of Luzon... After a short circle, he went directly from Luzon to the north, and crossed Taiwan directly to the Diaoyu Islands, and then turned from Diaoyu Islands to the Hangzhou Bay.

The whole journey took a long time to go and the time to come back was shorter, but the soldiers on the entire ship had accepted a real sea navigation, which somewhat increased some experience in sea navigation.

After returning to Qin Mansion, Xiao Heng ordered the soldiers to disband on the spot and asked them to go home and have a good rest. He took Guan Lin, several students of Xiao Heng and the soldiers and the leader of the soldiers to eat something in the wing room, and talked about their experiences along the way.

"This voyage is a complete success. The first thing is the captain's contribution... I respect you." Xiao Heng said that, and then he did it first.

"I dare not, don't dare... This trip has benefited me a lot, especially Mr. Xiao's disciple, which is really eye-opening!" Guan Lin quickly responded to Xiao Heng with a cup.

"Where is there, if you don't have Captain Guan's experience, the risk of this trip is still very high..." Xiao Heng was not polite. After all, the water temperature situation these days is definitely completely different from that in modern times, nearly a thousand years later, so modern hydrological data are useless at all. It can only rely on Guan Lin's experience in sailing for so many years.

"No, I'll tell you the truth." Guan Lin poured himself a cup and sighed, "To be honest... what kind of navigation clock and sextant that the young master had told him before... I don't believe it."

For Guan Lin, who has been working hard at sea for many years, whether it is a complex sextant or a more complex navigation clock, they are all fancy things, far less reliable than his intuition and experience.

When they traveled westward, whenever Xiao Heng's students began to calculate the current coordinates and started to re-draw the coastal chart based on this, Guan Lin sneered at him... What's the use of doing these tricks?? Do you have to look at the needle road map obediently?

In this era, sailing was generally near the coast, and when sailing, you could usually see the land from afar on one side of the ship... The advantage of sailing in this way is that you will never get lost.

The appearance of the needle road map made the captains' choice of routes more radical, occasionally leaving the coast out of sight, but as long as the direction is correct, you can quickly re-see the land.

But in this way, you need to re-correct your position every time you see the land again... and this is the value of the needle road map. It is not only a few routes, but also a nautical chart recorded in words, which allows the captain to understand his position.

But this is not without any harm, that is, the speed is too slow...

When they drove back from Luzon, several Xiao Heng's students took over the navigation command of the ship.

This time, when I came, the students who had mastered the sextant and the navigation clock drove the boat directly to the outer sea! Then they crossed a large area of ​​sea along a straight line and then returned to Hangzhou Bay.

To be honest, when the students drove the boat to the outer sea, Guan Lin's heart was suffocated... Fortunately, he had experience in the past Japanese routes, so he knew very well that if he was lost, he would definitely see the coast as long as he sailed to the west, so he was not panicked yet.

What shocked Guan Lin the most was of course the day he saw the land after a long voyage... Of course, this scene was actually used to Guan Lin, but this time it was different, because this time he knew where they would arrive in advance, and when the land appeared, he repeatedly confirmed it and found that it was indeed Hangzhou Bay!!

It can be said that when Guan Lin saw Hangzhou Bay, his entire worldview was refreshed! How can people know where they are? In Guan Lin's simple impression, of course, he has to see if the surrounding scenery is familiar!

But now, Xiao Heng's students do not need to look at the characteristics of the shore or measure the hydrological conditions. They just need to look at the navigation clock and then look at the sun, and take a pen and calculate it slightly to know where they are!

This is a bit terrifying! For Guan Lin, this is tantamount to Zen Star Technology!

Although Xiao Heng had mentioned before what kind of chemical reaction would occur after the combination of the compass, navigation clock and sextant, Guan Lin had never paid attention to it before because he felt that Xiao Heng was just a scholar who was angry and made something flashy.

But when the facts were in front of him, Guan Lin was dumbfounded but was also a little happy to see the hunting...

...If you can learn this kind of skill, wouldn't you go wherever you want?

Guan Lin has been holding back this idea all the way. When he saw Xiao Heng on the pier, he almost asked. Now he has already been on the table, Guan Lin can no longer help but ask his questions. After tribute to Xiao Heng for a drink, he couldn't help but speak with shame:

"Can Mr. Xiao solve my doubts? How did this happen?" Guan Lin asked sincerely, "Of course, if the young master doesn't want to say it, it's fine. I don't want to find out about the young master's unique skills, but... I just don't understand that I really can't sleep!"

"Actually, it's not difficult, it's just a little troublesome to explain." Xiao Heng smiled.

Guan Lin immediately ignited a glimmer of hope when he heard this: "So... the young master is willing to teach me?"

"Well, for this kind of problem, you have to study geography first... Uh, you have to learn physics."

Xiao Heng did not satisfy him immediately. After all, this kind of thing is still a bit complicated to explain, especially for people like Guan Lin who are still in the "round sky and place" and have no idea about the earth and the world, it is even more difficult to explain clearly.

Xiao Heng didn't want to explain to Guan Lin the silly question of "why those standing on the other side of the earth won't fall down."

"..." Guan Lin was a little confused and didn't know how to learn the "geography" and "physics" mentioned by Xiao Heng.

"In this way, our school will welcome a group of new students. Then you can follow them... and use this time to rest and rest."

Xiao Heng said.

"New student?" Guan Lin was stunned.

"That's right, a new student." Xiao Heng nodded.

This group of so-called new students are actually the shipyard children who intend to learn to calculate the characters, and there are also young apprentices.

The community on the shipyard is not like Xiao Heng and others was completely established by him, and the personnel were also screened out from the escaped people from all over the country. Whether it is setting rules or gathering people's hearts, it is relatively simple.

The shipyard has always continued the tradition of the shipyard, and this barrier cannot be broken in a short period of time - even under money and more humane rules and regulations, the shipyard's tradition of "respecting teachers and respecting the way" is still difficult to break, and those students who were already independent still have signs of relying on their respective masters...

...It was precisely because of this sign that Xiao Heng accelerated the progress of enrolling children in the shipyard.

It is difficult to change the minds of adults without major changes, but children are different. Children's values ​​and worldview have not yet been established, and they are more malleable... This way, it is much simpler to change customs by educating them than to force shipyards to strictly enforce rules and regulations, and the sequelae are smaller.

At this time, Guan Lin didn't know who he was going to learn with. After hearing the word "student", what he thought of was naturally Lu Chun and his group of students who impressed him deeply.

"Okay! I wonder when I will be able to enter school?" Guan Lin made a secret decision to study hard. No matter how many difficulties and difficulties you have, he must understand the secret of the navigation clock and sextant until the end.

"Uh... tomorrow, if you want," Xiao Heng said.

"Okay! One word is determined!"

Guan Lin lived at such an old age and had experienced many things, but the only thing about going to school was that he had no idea about it in his mind.

So the next day when he came to school with a student ID with a bright red seal on his back, he was confused and was assigned to the same class by several teenage "little teachers" and a group of six or seven-year-old kids.

Then Guan Lin was taken to his class in a daze, got his seat, and even got his own student number - No. 15.

Only when class was in, Guan Lin realized, looked at the little kid classmate next to him, and then looked at the little teacher who was only eleven or twelve years old in class...

"Students stretch out their hands and take out your left hand... see how many fingers there are on your hand?"

"After reading... there are one, two, three, four, five fingers!"

"So what is one finger and one finger?"

"So classmates, what I learned today is... what is one plus one equal?"

"Equal to...two!"

The ordinary black-faced uncle Guan Linguan, who was galloping across the ocean, had experienced many battles, killed and robbed people, was a normal black-faced captain Guan Linguan. He followed a group of breast children to stretch out his left hand and compared it with a "v" shape.

At this moment, he wanted to find a crack in the ground to get into it.
