Turbulent Times Chapter 1029: Go to sea

This young man was the best among the first batch of nautical professionals trained by Nie Xiaoyu. His name was Du Haiwa, and he was assigned to Wang Junlin's ship with two other people to be in charge of navigation.

At this moment, Zhang Tiangang finally couldn't help asking questions about the unfamiliar term that popped out of Du Haiwa's mouth again.

"That's right, what I just said was ocean currents."

"The so-called rivers have currents, and the sea also has currents! Those who go to sea all year round will know that the same ship, the same cargo, the same calm, the same mileage, sailing with ocean currents and sailing without ocean currents The time spent is very different Big, sometimes even save half the time.”

"What caused this situation is the ocean current I just mentioned. This principle is actually the same as sailing in rivers on land. If you go downstream on a big river, it will be fast, but if you go against it, you will be like sailing against the current. It's not slow."

"So that's it, I understand." Zhang Tiangang nodded, and the others also suddenly realized.

Wang Junlin also looked at Du Haiwa, and nodded with admiration. This son was originally a pirate who survived on Snake Island. He grew up by the sea since he was a child. He already knew his temperament very well. After being systematically and professionally trained by Nie Xiaoyu, he could indeed be called a nautical professional.

It's just that for some reason, every time Nie Xiaoyu is mentioned, the awe and admiration of this child is very similar to the expression of ordinary people when they face the legendary gods and demons.

Seeing that everyone understood, and even the prefect expressed his appreciation, Du Haiwa imitated what Nie Xiaoyu did when he was giving them a lecture, and drew a line and an arrow on the chart with a charcoal pencil, and then Pointing to this line, he said: "This is the target route we are going to. With this route, we can save a lot of wasteful roads and reach the target point in the shortest time. And we will not run into reefs. It can even avoid some places prone to tornado storms."

"I see."

Zhang Tiangang led the crowd to nod their heads one after another. What Du Haiwa said was very clear.

Wang Junlin sat high in the hall of the big ship, and let Du Haiwa explain some maritime knowledge such as "ocean currents". Although he has rich sailing experience, it is Nie Xiaoyu who gave him all this.

The two coastal currents that Du Haiwa just mentioned have their roots in the "Yellow Sea Warm Current", which is a branch of the "Kuroshio Current", the second largest ocean current in the world.

The Yellow Sea Warm Current flows northward along the west coast of the Korean Peninsula. Near the Yalu River, due to the action of the Liaodong Peninsula, it turns to the southwest. Under the action of the Yalu River current, it becomes stronger and rushes directly into Bohai Bay!

This warm current will circle along the coast of the Bohai Bay, take away the heat, make Qinhuangdao an ice-free port, and then flow out from the southern side of the Bohai Sea. In the vicinity of Yantai in later generations, it received fresh water from Laizhou Bay, turned it into a coastal current of the Yellow Sea, bypassed Chengshanjiao, and continued to flow south...

Understanding this, you can make full use of ocean currents to sail your boat.

Du Haiwa continued: "It is already summer now, and the current in southern Liaoning is weak, which is enough to make it difficult for boats to sail. In autumn and winter, the ocean current will be twice as strong! It is really difficult to set off to the island we are going to! It will take a whole month to go back and forth!"

For this era, there are very few ocean voyages away from the coast. First of all, the sea is unpredictable. Paddle.

What's worse, after losing the landmarks on the land, the course of the ship has become a problem. During the day and clear night, you can rely on the sun, moon and stars to judge the wind direction, but on cloudy and cloudy nights, the ship The team became headless chickens and lost their way... The unlucky ship crashed and the people died. If the luck is good, it will be the year of the monkey when they finally get back.

"Let me tell you about the common sense of observing wind direction at sea."

Du Haiwa was just the lowest-level little pirate among the pirates of Snake Island before. The interest became higher and higher, and he continued: "At present, in the area of ​​the Bohai Sea, the sea breeze usually blows from east to west, so it takes a lot of effort to sail long distances, but if it comes to autumn, it will be just the opposite. It can be said that It’s God’s help!”

"God help him?" Zhang Tiangang frowned slightly, and said, "What do you mean by this sentence?"

Du Haiwa lightly drew some small arrows on the chart he drew by himself. East to northeast...

Zhang Tiangang and the others looked at these small arrows with a dazed expression, not knowing what they were.

Du Haiwa put away the charcoal pencil and said with a smile: "These arrows represent the monsoon at sea!"

Same as 'Ocean Current', the word 'Monsoon' was also spoken by Sir Siren. Du Haiwa feels that these words are too accurate and vivid, and only Sir Siren can say such a word .

Of course, the word monsoon is not as exaggerated as Du Haiwa imagined. It is actually very simple. To put it bluntly, it is just as the name suggests, because the word is very realistic. The so-called monsoon is the sea breeze that appears as the seasons change. !

"Du Haiwa is right."

Wang Junlin saw that it was getting late, and Du Haiwa and the other two navigators took turns to rest well, because during these few days of sailing, Wang Junlin, Zhang Tiangang and their guards had nothing to do, while Du Hai The baby must be nourished. So he suddenly made a sound, attracting everyone's attention.

"With the help of the monsoon wind, a ship on the sea sails far away, crossing thousands of miles of sea, like a flying horse flying, and conquering overseas countries is as easy as turning the palm of your hand!"

…

…

The sea at night is more terrifying than daytime, deep and unknown, with countless dangers lurking. Even the most seasoned fisherman seldom sails at night.

But Wang Junlin and his group of hundreds of ships shuttled across the sea overnight, sailing in the vast sea.

At night, when the moon was waning, Wang Junlin stood on the bow of the boat and looked up at the sky, but he saw that the sky was clear and cloudless, and his field of vision was extremely empty. Afterwards, the stars and the Milky Way appeared extraordinarily clear and beautiful, and the stars also appeared extraordinarily numerous.

Du Haiwa slept for three hours in the afternoon, and it was his turn to navigate at night. At this time, he was staring at the stars in the sky, and adjusted the navigation direction from time to time.
