After the fourth master and I wear each other [Qing wear]

Can't find North is not just an adjective at this time.

The strong wind and heavy rain kept the ship bumping.

Yinzhen was suddenly switched into his body, and he didn't get any memory left by Wu Fuyi at all, so he had no way of knowing the specific situation in front of him.

Which sea area is this in?In which direction should it go?How long can the ship go?

In a storm of lightning and thunder, there is no way to use the stars in the sky to locate the direction and direction of progress.

Yinzhen didn't even know what the old ghost had done, which caused a whole boat of people to look forward to him as if they were the incarnation of the sea god.

He obviously doesn't know what to ask, but he still has to be extremely calm.As if the situation had not reached the point of urgency, it was still possible to ask Yinzhen questions.

"Ninth brother, after reading those books, what do you think will happen next?"

Yinzhen has no way of knowing what the old ghost said to everyone before the exchange, but at least he can be sure that this trip to Dongying will definitely send Lao Jiu to study when he has nothing to do.

Why can you be sure?

When in the capital, a bunch of people were either actively or passively persuaded by the old ghost.

With a lot of free time at sea, Yinzhen can't escape learning from the endless hardships of the sea.

At this time, it is most difficult to throw out this question.

Yinzhen waited for Lao Jiu's answer to judge the situation in front of him.

"what?"

Yinzhen didn't expect that the fourth brother would throw the unfinished words to him.

What is the use of those books he read a few days ago, and none of them mentioned what to do in case of a severe storm at sea!

Fourth brother, his good fourth brother, why test him at this time.

Before, the fourth brother was not like this.

When approaching Nagasaki Port, I encountered a surprise attack by a giant octopus.He persuaded the fourth brother not to risk himself, because the book said that sea monsters are difficult to deal with.But the fourth brother didn't listen to what he said from the beginning to the end, so he just copied the guy and went to the boat to kill the fish.

Right now, Yinzhen is dizzy from the turbulence of the waves. After listening to the fourth brother's question, she becomes dizzy even more, and feels that the fourth brother's personality really changes.

Before Yinzhen could figure out why, the captain spoke first.

"Fourth Lord is right. The evil wind prevented the ship from landing on Shikoku Island and turned the ship to the southeast. It's not all a bad thing."

The captain doesn't care about the dignity of master and servant, so he has to speak up in time if he has something to say.He is wearing a crime, carrying the charge of smuggling for Suo'etu. This trip to Japan is an opportunity to make a contribution and must be seized.

Since I have been traveling on the Dongying route all the year round, I can speak a few words of Dongying dialect.The masters were socializing in Edo Castle, and he was not idle.

You can also inquire about some news in the market, such as the situation of sailing in the ocean around Dongpu, are there pirates?When is the most stormy season?What little-known islands have fishermen accidentally visited when they yaw in the wind and waves at sea?

The captain told what he knew, "I have inquired with the fishermen of Dongying. There seem to be a group of unnamed islands in the south of Dongying. The islands are like spring all the year round. Now, everyone just insists not to be thrown out of the boat."

When Yinzhen heard the words, he immediately understood the current situation. He grasped the key points in the captain's words, Shikoku Island and the unnamed island in the southeast.

Although the sea wind, waves, and torrential rain slammed on his head like a combination of fists, and the boat kept shaking so much that he couldn't even spit out, his thinking and judgment did not stop.

Since I have read the self-rescue guidebook compiled by the old ghost thousands of times, I have already mastered those contents by heart, and immediately corresponded the current situation to the map drawn by the old ghost in the book.

If the ship sails all the way to the southeast, it will encounter a series of southern islands outside the East Ocean Territory.These islands are not big, some are full of sulfur, some are volcanic islands, and some are full of rare birds and animals.

"Everyone cheer up and survive this storm."

Yinzhen called the captain's name first, and now that he has confirmed the general situation, he must act against time. "Lin Dayuan, first pay attention to whether there is any damage or leakage at the bottom of the boat."

The wind and waves suddenly hit, and a group of people were caught off guard and stranded on the deck.

Orderly arrangements are to be made now, and attention must be paid to guarding the various conditions of the hull.

In case the ship disintegrates and people have to drift with the current, it is best to carry one or two necessary self-rescue items and jump into the sea to escape.

With a firm tone, Yinzhen began to arrange work one by one.

Everyone looked at Fourth Master's orderly appearance. Although the storm that came in was terrible, they had more or less found the backbone, and they were not so flustered anymore.

In fact, whether or not Yinzhen is uneasy and at a loss in his heart, I am afraid that only he himself knows.

The words are divided into two parts.

From hell to fairyland, it seems to be an instant.

Wu Fuyi returned to Wu's body.

The violent storm instantly turned into the singing of birds and the fragrance of flowers.

Outside the window, the sun was shining brightly, and the October afternoon sun made people drowsy.

Sitting in the rocking chair comfortably, with a tea table on one side, the tea aroma of Lu'an Guapian wafts out of the cup.

He is holding a notebook in his hand, which is the guide to self-rescue in shipwreck.Seeing that even the pages of the book are torn, and Yinzhen's dense annotations are all over the book.

For example, how to determine the position at sea on a starless night?Apart from the seaman's experience, is there no accurate tool?

For example, if you worry about your soul, and imitate the process of monkeys climbing coconut trees and drinking coconuts as water, can you really ensure that you don't fall off?For him, which way of death would be more enjoyable, death without fresh water or falling to death while fetching water?

Wu Fuyi couldn't help laughing when he saw these comments that seemed to be sarcasm.

It was her mistake, time was running short, and she was only able to train Yinzhen to swim, but not to train him to climb trees.

Although the Eight Banners field battles also have the ability to climb, Yinzhen should have returned it to the teacher long ago.Even if he once went to Galdan with the army, it was not his turn to bravely climb the heights to spy on the army.

Surviving on a deserted island requires climbing trees.

To draw water from the island, one cannot miss the coconuts bestowed by God.But the coconut trees are very tall, and you have to climb about 20 meters to pick coconuts.If you fall down, you can go directly to drink tea and chat with Hades.

"Blessed by the Buddha, Yinzhen will survive this calamity."

Wu Fuyi muttered a word without distraction, and didn't worry much about Yinzhen.

Now that they are separated by two places, even if she has the heart, there is nothing she can do to help other things.I just hope that Yinzhen will recognize the reality and don't act recklessly, and don't rush when it's time to admit defeat.

Stretching her waist, she called Guanshuang and asked the back chef to serve two desserts.

When traveling abroad, although there are delicious seafood that can be eaten endlessly, there are always some foods that cannot be eaten.

Such as milk cakes, such as mutton pot, such as all kinds of juicy vegetables, you can arrange every meal from today.

I don't know how long this exchange will last. If the fourth prince's physical suffering is used as the timing standard, it will be ten days and a half months at least.

The good news is that I can relax during this period, but it also verifies the unpleasant point from the side.

Even if they go out of the country, the soul bond between the two never stops, and the geographical distance cannot prevent mutual penetration.

Don't even think about the freedom of being alone, you can only hope that one day the fourth elder brother and the Wu family can enter and leave the capital without restriction.

However, Wu Fuyi quickly adjusted his mood.Fortune and misfortune depend on each other, and she never seeks to take up all the good things.

During this leisure time, you will not be so decadent that you have nothing to do, so you might as well find something interesting.I got one or two inspirations from Yinzhen's pile of Tucao comments.

Yinzhen asked the question, is there anything that can accurately locate the position of the ship?

Although GPS navigation is still out of reach, it is not impossible in this day and age.

Longitude and latitude, people have been exploring how to determine their values.

Experienced sailors can calculate the latitude by observing the sun during the day and the Polaris at night through the conversion of altitude and angle.If you think the latitude obtained in this way is not accurate enough, you can also use the quadrant.

This quadrant for observing latitude is said to have first appeared in ancient Greece.

Wu Fuyi also saw the real thing in the Qin Tianjian in the capital.

When Kangxi was a teenager, he made a quadrant with the help of Nan Huairen.It is said that the original intention of this thing is to assist in calculating the precise shooting angle of the artillery.

Use the quadrant on the ship and just go one step further.

At the end of the sixteenth century, the Englishman, John Davis, invented the rod projector.Instead of looking directly at the sun, latitude can be calculated by observing the shadow.

However, latitude is easy to obtain, but longitude is difficult to measure.

From the beginning of the age of great navigation to the present, there is still no precise longitude measurement tool.

Wu Fuyi not only dismantled a ship in Songjiang Mansion, but also asked the crew who often go to sea how they locate the longitude now.

Although the crew of the Qing Dynasty hadn't heard much about the professional vocabulary of longitude, they also knew that they were traveling in different directions from southeast to northwest.

At present, since there is no longitude measuring instrument, the orientation is mainly determined according to the chart and the control speed.

Veteran sailors can roughly know the speed of the hand and the distance they can drive by the feel of the helm.New sailors are not sure about the speed, so they calculate the speed by putting the length of the knot in the sea, but this estimation is not accurate.

If there is no chart left by the predecessors for this route, it will be lost. It is best to travel along the same latitude.The earth is round, and in theory it can always come back once it goes around.

A theory, after all, is just a theory.

In the process of sailing, unexpected situations caused by weather changes are actually the norm, and it is common to deviate from the course for a while.

Therefore, in order to achieve relatively safe navigation, longitude measurement is urgent.

Wu Fuyi decided that the nautical clock could be built.

The principle of this thing is not difficult for students who have studied geography in later generations.

It takes 360 hours for the earth to rotate 24° once.That is to say, every 15 degrees of longitude, the local time difference is 1 hour.

Suppose you know that it is 15:[-] in the morning in a certain place and it is [-]:[-] in the morning in Beijing, you can know that a certain place is east of the capital, and the longitude differs by [-]°.

A person in a certain place can estimate the local time through the sun or stars. The current difficulty lies in how to know exactly what time it is in the capital?

The answer seems simple.

Carry a clock that runs accurately and displays the capital time on time.

A nautical clock is a precision measuring instrument that is not affected by various factors such as wind and waves, temperature, and humidity at sea.

Some people may think that it is just a kind of clock after all, what's the big deal?

But it is to say that the timing technology at this time cannot be judged from the perspective of future generations.Precise measurement is difficult to know and easy to do. Western countries have not yet developed sea clocks.

Today's Western clocks on the ground are also inaccurate and very heavy.

There were bells in the Qing Dynasty. They were not developed by themselves, but self-ringing bells imported from the West.

In fact, Kangxi also set up a self-ringing bell office.

This place is also affiliated with the Building Office of the Hall of Mental Cultivation, but the place where the bell rings is even more unknown than the glass factory.I haven't heard of any new tricks it has come up with. The people inside can only do maintenance, repairing the few western clocks.

Wu Fuyi's hand itched just thinking about it.

Last year we made a fuss about the glass factory, but this year we made a fuss in a different location.

Different from taking out the formula for glass, to develop a clock, you have to get started first to see how far the current technology has developed.

It's a pity, now that I have Wu's identity, I can't go to the palace to have a chat with Kangxi immediately.She didn't want to destroy it, but just wanted to "borrow" a few chime clocks to dismantle them and find out the feeling of making precision clocks.

Hey, I am so busy that I am used to it.

Even if it's rare to be free, I'm still a little restless and itchy.

Qianqing Palace.

"Clang clang clang..."

At Shen time, at three o'clock in the afternoon, the chiming bell rang three times.

Kangxi glanced at the gilded Western chime bell.

This thing is so bulky that it is half the height of a person, and it is studded with all kinds of jewels. It was carefully sent to the capital from Guangzhou Port all the way.

At this moment, he didn't pay much attention to Zhong, but thought about the situation of the fourth and ninth sons.

A few days ago, Jiang Customs came with a note, and the ship carrying the real money paid for the goods docked and entered the country first.

The decision made by the fourth child is to let the payment be returned first, and the bag will be safe.As for people, it will be a while later, and Dongpu must be thoroughly investigated.

Kangxi learned that the round trip of the cargo ship was relatively smooth, and he hoped that the fourth and ninth sons could do the same.

When people come back, no matter how much they find out about Japan, there is hard work without credit. Let them choose some rewards by themselves.

At this moment, how could Kangxi think that as soon as the fourth child returns to the capital, the expensive chime bell he owns will not be far from "five horses to divide the corpse".
