Five new ships were moored in the harbor, but out of the ships were the soldiers of the Maritime Trade Corps who had been tossed and bustled, and those men in the army, who had always been tough, could not subdue the stormy waves of the sea.

This situation made Li Qi, the captain of the sea wolf guard, Peng Tonghe, and Zeng Lei, the captains of the school, a little unbearable on their faces, and after saluting Liu Fengfeng with a smile, they lowered their hands and stood respectfully.

The end of June is the windiest season at sea, and although Bohai Bay is the windiest bay, there are also six or seven strong winds.

But for these sergeants who have just been retrained, it is a great test, not only to test the control of the ship by the Sea Wolf Guard, but also to test the willpower of these non-commissioned officers of the Sea Trade Corps who have boarded the ship for the first time.

However, this time the sea is still very rewarding, looking at the three principals of the sea trade group, although their faces are also full of exhaustion, but the interest on their faces can not be hidden.

Those sergeants had their own logistics personnel to arrange and take care of them, and Li Qi, Fu Ziyong and others cleaned up a little, and then followed Liu Feng to the meeting hall of the shipyard.

Seeing that everyone was holding on to their tired bodies, Liu Feng said with a smile, "I heard a poem, but I don't remember it very much, but there is a sentence that has a profound impact, '10,000 years is too long, seize the day!'" ’”

"Maybe it's because I'm in a hurry, the sea is not so easy to conquer, and it's not so easy to make a living at sea, but I don't dare to relax in the slightest, because the current situation is imminent!"

While explaining a little to everyone, he slowly unfolded a huge sea chart, which was another work carried out by Liu Feng in the shipyard, after combining the oral accounts of some seafarers who went to sea, he connected several painters according to his own memories and carefully drew a map of the world.

Of course, the map is not as accurate as that of later generations, especially many islands in Southeast Asia, Liu Feng doesn't remember much, but he just roughly marked out several continents, oceans and places where maritime merchants often go.

This map is definitely the first world map in this world, even the living HNA family does not have such a detailed map, because they are far from Liu Feng can clearly understand what the world is like.

And when this nautical chart slowly unfolded, everyone's eyes and expressions became a little different, the tired look was swept away, and the tired red eyes became extremely focused, staring closely at the drawings on the table.

Among them, Gu Ziyong's feelings are the deepest, among these people, his insight is the most extraordinary, in his mind, there is a nautical chart, but at this moment, after seeing such a detailed and complete map, one is to verify the accuracy of the map in his heart, and the other is to be surprised by Liu Feng's ability.

Although Chuan Jian and Liu Sui did not express anything, they never looked away from the map, Guangzhou, Nanyang, Ceylon, Dashi, etc., on this drawing, they can see through it at a glance.

And when their gaze crossed the vast Pacific Ocean and fell on the North and South America and other regions, they couldn't help but feel the novelty, where the large area of land, they couldn't help but be surprised, it was a place they had never been to.

There is no doubt that Liu Feng used a map to once again impress these arrogant talents, and the eyes full of question marks in the hall looked at Liu Feng, in addition to their questions, they also had more determined eyes, and they believed that Fan Yang Mansion could go longer and longer, and their Sea Wolf Guard and Sea Trade Group would also go to the four seas.

Fu Ziyong, who was hooked by the map, was still immersed in the map, and asked involuntarily: "Oceania, North America, South America, Europe, Africa, Antarctica, Atlantic, Indian Ocean, Arctic Ocean...... Where exactly are these places? ”

"Where you'll all be in the future!" Liu Feng said lightly,

Seeing everyone's questioning eyes, Liu Feng began his explanation, "In our world, two-thirds of the area is covered by water. The ocean, much bigger than our land. On our planet, there are a total of seven large landmasses, and the largest of them is the land we are on, which we can call the Eurasian continent......"

After a pause to make everyone understand, he pointed to the vast ocean in the middle of the map, and continued: "This ocean is called the Pacific Ocean, which is much larger than the land where we are located, and even wider than the farthest place from here to the Western Regions. ”

"All the earth's oceans are interconnected, which means that if we have a ship that can sail forever, then we can go out of the high city, bypass all the oceans, and then return to the high city. Hopefully, one day, one of you will be able to circumnavigate the Earth. ”

He pointed to the Indian Ocean and said softly, "This ocean is called the Indian Ocean, and India is what we call Tianzhu, and when we cross the South Ocean to the Great Eclipse Route, it is in the northernmost part of the Indian Ocean. ”

The more they talked, the clearer they became, but the more confused they became, Fu Ziyong was the first to react, "Envoy, is this earth a ball?" ”

Everyone looked at Liu Feng with the same question, this is a concept that subverts their common sense, there is a way, the sky is round, the sky is round, the earth is square, everyone is convinced.

Liu Feng did not have a profound explanation, because this problem was easily solved after they sailed around the world, but in fact, there are still many ways to verify this problem, such as a ship on the sea level coming from afar, always seeing the mast first, and then seeing the hull,

He drew a circle on a blank piece of paper and explained to them in detail what the ocean was about and why the earth was round.

While explaining the knowledge of the ocean, of course, it involves the knowledge of the whole earth, so Liu Feng had to take out the "Basic Knowledge of Navigation" compiled and sorted out before, and explain the simple knowledge about the earth, land, ocean, climate, seasons, and trade winds in detail for everyone.

Although Li Qi and others have read books and understand some of these knowledge, in this era, no one can systematically understand and understand this knowledge, even those great Confucians in Fanyang Academy do not know much about these natural knowledge.

In the next few days, Liu Feng acted as a teacher, explaining all the navigation or natural knowledge to the sea wolf guards and the sea trade group every day.

For nearly half a month, Liu Feng has been explaining to them the basic knowledge of the world, of course, there are some things that Liu Feng does not know, that is, detailed hydrological data, including water temperature changes in the sea area, water quality characteristics, sea ice, waves, tides, currents and so on.

But the Sea Wolf Guard and the Sea Trade Group have the most unique conditions, they have basically understood the ocean and the world, and the next only need is to combine these theoretical knowledge and practice and continue to explore the sea, and the development of Fanyang Mansion is just around the corner.

In fact, human beings' yearning for the sea existed before the Spring and Autumn Period and the Warring States Period, but at that time, people's understanding of the sea only stayed on the surface. When the Chinese really go out to sea, it is only after the Tang and Song Dynasties, especially after the Song Dynasty, that the maritime trade in the Nanyang region is truly developed. In the Ming Dynasty, Zheng He went to the West and reached a peak state, and then declined rapidly.

Liu Feng will not let the maritime trade continue unorganized, and at the same time as the establishment of the maritime trade group, he also set up a ship department to manage the maritime trade in a unified manner, and vigorously promote various ocean-going navigation technologies.

The Maritime Trade Corps is an armed maritime trade group under the jurisdiction of Fanyang Province, and the Ship Department is to manage and guide the maritime trade of the entire Fanyang Province, and vigorously develop shipbuilding technology.

To vigorously develop ocean voyages, there are many technologies involved, the compass is indispensable, in the vast sea, relying on the sun, moon and stars to determine the direction is not very reliable, only the use of the compass, in order to effectively and accurately ensure the direction of the ship's progress, there will be no large deviation.

When building ships, it is also urgently needed to improve the ship's ability to resist wind and waves and sink, and the five new ships of Gaocheng Shipyard are using technologies such as sealed cabins to improve the ship's ability to resist wind and waves and resist sinking.

However, the navy is definitely a branch of the armed forces that burns money, and if there is not enough financial revenue, they will not be able to sail half a step to the sea at all, and only by combining trade and development can the development of the navy make great progress, and this is the most fundamental way to take it from the sea and use it for the sea.

Liu Feng stood on the five newly built battleships, worried about one thing, that is, their five battleships had not yet been loaded with weapons, and they were originally intended to be loaded with artillery, but the gunpowder battalion has not been able to reduce the barrel explosion rate so far, which makes Liu Feng a little annoyed, maybe the next step, he will be stationed in the gunpowder camp for some time.

When he was melancholy, he saw a meat ball climbing up from the rope ladder, looking at it from a distance, it looked like a fat worm wriggling, Liu Feng really couldn't stand it, and motioned to Zha Xiong next to him to go and help.

It took a lot of strength from a few guards to pull Xu Fu onto the deck of the ship, looking at the panting Xu Fu, Liu Feng smiled and said, "What are you making a fuss about?" ”

That Xu Fu's face was full of fat and he could even smile, "The merchant ship you went to Japan with my Xu family's fleet will return today, don't you go and see what the harvest is?" ”

Liu Feng snorted coldly when he saw him selling Guanzi, "Looking at your appearance, you know that you will definitely benefit a lot from going to sea this time." ”

Xu Fugan laughed a few times, "Alas! Let the envoy guess that this harvest is not only expensive, it is a lot of money, how can the weapons of Fanyang Mansion be so popular!? This trip to the sea has an income of nearly 100,000 taels! ”
