Jack shrugged his shoulders and said: "Who asked me to be the deputy bosun? You know this is not a popular position on the ship. But fortunately, everyone respects this position. And they can't beat me in a fight, let alone me.

I've been on the boat longer than all of them. So naturally they listen to me."

Liu Pei nodded and said: "Okay, I understand. Let's start practicing now."

Jack bowed and said, "As you wish."

After saying that, he turned back and gave orders to the servants. The servants moved quickly under his order. Some people quickly climbed up the mast, moving like apes. The people on the deck ran non-stop, and in cooperation with the people on the mast, they moved one by one.

The sail was lowered, and the movement was very skillful. The whole process was repeated twice, and it went very smoothly. It can be seen that I have put in hard work.

At this time, Liu Pei suddenly shouted: "The south wind is blowing now! The wind is very strong, level 7 wind."

Jack was stunned for a moment when he heard this order, and then he reacted and issued a series of orders: "Raise the jib in front. The helmsman stabilizes the course. All mainsails are lowered one notch! Everyone fastens the ropes."

The calculations moved quickly according to the order. In a moment, all the main sails were lowered by one space. The jib was also quickly pulled up. Liu Pei saw that the actions of the servants were all in place and couldn't help but nodded with satisfaction. Even

Jack also made a proud face to Liu Pei.

But how could Liu Pei let them pass so easily! Then he shouted loudly: "The wind is northwest. Level eight wind."

Jack, who was well prepared, immediately shouted an order: "Hold up the jib! Lower all the mainsails one more space. Attention, helmsman, sail in a zigzag pattern. Sailors who time the boat, pay attention to time."

Following his order, the sailors took action again and still completed all the instructions accurately. Liu Pei immediately issued two more orders, and the servants completed them beautifully! So Liu Pei said to Jack: "That's it.

Beautiful! Jack, you have done a great job! I announce that all of your salaries will be doubled this month!"

The foreign sailors cheered quickly after hearing Liu Dahai's translation. Liu Pei then said: "Because of your outstanding efforts, your monthly salary will be increased by 20%! At the same time, I appointed Jack Jack as the instructor team

The chief instructor. His salary will be increased by 50%!"

Jack said excitedly: "Boss, you are such a good person! You are as generous as God!"

Liu Pei said: "So do you still have any problems that need to be solved while living here?"

Jack said with a smile: "Ah, of course! My boss, a big problem, you seem to have restrictions on drinking here. You know, sailors can't live without alcohol!"

Liu Pei said

: "I'm sorry, this is not negotiable! This is to prevent you from being drunk and giving wrong orders every day. I have already explained that you can drink alcohol, but you must not get drunk. So your daily drinking must be limited!"

Jack said unhappily: "Okay, boss, we can accept this. But there is a more serious problem. That is, there are no women here, all men. This is terrible! And we have been to a brothel, but

The brothel refused to accept us! They even called us barbarians! I don’t know what barbarians mean, but I guess it’s not a good term!”

Liu Pei laughed secretly in his heart after hearing this. At this time, the people of the Ming Dynasty were extremely confident. In their eyes, except for the Han people, everyone else was barbarian. This was different from those exquisite and refined bastards in later generations.

But this is indeed a big problem. Since Liu Pei no longer plans to let them return to China, he naturally wants to help them solve this problem.

So Liu Pei thought for a while and said, "Okay, I will help you solve this problem. How about finding a wife for each of you?"

The cheers became even stronger now. The sailors who didn't speak Chinese yet kept praising him in their own language. Then Jack raised a few more minor questions, and Liu Pei also agreed to help solve them as soon as possible.

After they finished asking the questions, Liu Pei said: "Then do you think there is anything else that should be paid attention to during training?"

Jack said: "Boss, I was stunned by your genius creativity today! This method of simulating wind direction is very good! It can quickly make sailors familiar with the situation at sea. So I think these people can still train for a while.

Time. This way they will be able to master the essentials of navigation more easily after boarding the ship."

Liu Pei was also very proud and said: "Then implement it as soon as possible, understand? Are there any other questions?"

Jack then said loudly: "There is another idea, which is the idea of ​​nautical clocks and longitude and latitude lines! God! I never thought that there are smart people like you in the far east! They will save the lives of countless sailors.

!It can also save time on sea voyages! You should promote these inventions to the world!"

Liu Pei said seriously: "Jack, don't even think about this! These secrets must be kept in our fleet. Don't forget that you are getting my salary. In addition, Jack, if you can keep it, you can swear to keep these secrets."

If you don’t spread the word, I can give you an extra reward of 100 taels each! How about it?"

Jack immediately gave Liu Pei a warm hug and said, "Boss, you are really more generous than God! Don't worry, we will never leak this secret!"

Of course Liu Pei is not worried about them leaking out. Because the people around Jack and other barbarian sailors are all

The people sent by Liu Jiang will closely watch every move of Jack and others. Once problems arise, Liu Pei has been told that they can be killed without mercy! You know, there are too many secrets in Liu Pei's fleet!

Just talking about marine clocks, they are more than a hundred years ahead of the world.

At that time, latitude was easy to determine when we were at sea. We could rely on the height of Polaris or the height of the sun at midheaven. However, it was much more difficult to determine longitude. We could only estimate our longitude by measuring ship speed and other auxiliary methods. More

Most of the time, the captain relies on experience to deal with it. At that time, shipwrecks often occur due to miscalculation of the position and the ship runs aground on the rocks.

In 1707, due to inaccurate positioning, four ships of the British fleet ran aground and sank, and more than 2,000 officers and soldiers became dead souls. This disaster sounded a wake-up call to the sailors, and they asked the government to solve the longitude problem.

The "cost of life" attracted the attention of the British Parliament. Adhering to the concept that "there must be wise men under heavy money", in 1714, Parliament passed the "Longitude Act" and declared in legal form: longitude measurement at sea can control the error to 1

If the error is less than 2/3 degrees, the reward will be 15,000 pounds; if the error is less than half a degree, the reward will be 20,000 pounds.

Seeing this, you can't help but ask, what is the relationship between longitude and clocks? This stems from a theory: time determines space (longitude). At that time, it was already known that the earth is a sphere, 360 degrees, rotating once every 24 hours, then, a

The hour rotates 1/24 times, or 15 degrees. Therefore, if you sail for one hour, it means that the ship's longitude has moved 15 degrees east or west. However, clocks cannot accurately tell time on land, let alone at sea.

Woolen cloth?

At this time, John Harrison, the son of a carpenter, appeared. Harrison was born in a carpenter's family in Yorkshire, England. Although he learned his father's superb carpentry, he did not inherit his father's business, but was attracted to mechanical clocks.

.

Harrison spent several years and finally developed the first-generation product H1. H1 is a huge monster, weighing a full 34 kilograms. Practice at sea has shown that the accuracy of H1 is relatively high. However, it takes up too much space. Until

In 1757, the H4 was born. This was a pocket watch with high precision. After sailing on the ship for 161 days and nights, its error was less than 1 minute. This is really a miracle!

As for longitude and latitude, Liu Pei proudly named his dock 0 degrees longitude! Anyway, in his opinion, the reason why everyone adopts the longitude and latitude standards set by the British is simply because the British were strong enough at the time. When he becomes stronger in the future,
Chapter completed!
