The size and layout of the warehouses in the North Harbor, as well as the distribution and docking of sea vessels, are extremely regular, and it is clear that this sea voyage is more for military purposes than for civilian use.

This is Chen Fang's most intuitive understanding of Beigang, because twilight has already started, Chen Fang can't go to the port to take a closer look, so he can only go to the palace arranged for the princess with the local officials of Beigang who received the princess.

Along the way, Chen Fang tried his best to observe the surroundings, on the basis of not arousing the suspicion of others.

The architecture of the North Port is mainly stone, and it is more like a European port during the Voyage of Discovery than the South Port.

The city is well kept, the streets are lined with drainage facilities, the streets are clean and regular, not like the European streets of the Middle Ages, with a lot of feces and urine, and an indescribable smell of the city.

Chen Fang paid attention to the street lamps on both sides of the street, the street lamps were very bright, and they should be lit with whale fat.

Before oil was extracted, the greatest use of blubber was as fuel, and street lights were one of the most important uses of blubber.

The two enter a huge stone castle with a strong European style. This is because when the Northern Han Dynasty began to build this place, most of the labor used was European.

Therefore, the construction style of the Northern Han Dynasty is more inclined to the European side, rather than the architectural style of the Tang Dynasty, nor is it like the style of the Han Dynasty in China.

The stone fort had reserved maids and slaves of both sexes, and as soon as the princess arrived, these men began to serve them earnestly.

The officials of Beigang retired, and Chen Fang went to the hall of the Stone Fort, where Chen Fang was shocked by the huge map in front of him at the first sight of entering.

Although there are some differences between the world map and the world map in Chen Fang's memory, it can already be 99% consistent.

This huge map of the world hangs all over the wall, and in the Pacific and Indian Oceans, there are even navigation routes, and the time and season are marked next to them.

Some dangerous places are deliberately marked, such as Bermuda, such as the Devil's Triangle in Asia, ocean currents, monsoons, and navigation lines, all of which are marked on these maps.

Chen Fang approached the nautical map and was deeply shocked by the various fine markings on it, which was the basis of the shipping of the Northern Han Dynasty.

With an understanding of the ocean, the wind direction and climate of different seasons, and the understanding of ocean currents, the Northern Han Dynasty has thrown off several streets from the Tang Dynasty and the Western Qin.

To sail across the ocean, a sea vessel is one condition, and knowledge of the ocean is another.

Obviously, the Northern Han has it.

Liu Yi saw him approaching the map, and also walked over, hugging him from behind, with his chin resting on Chen Fang's shoulder.

"Xiao Mo, my ancestor lived in this castle for a long time, this map was drawn by him himself, and the world said that my ancestor was incompetent and almost let the Han die. In fact, the world doesn't know that he is the most amazing genius in the world. ”

"His charts and notes completely changed the state of existence of our Han Dynasty, and the efforts of successive Han emperors in the future finally allowed our army to set foot in most of the land in this world, and allowed our sea ships to gallop across the ocean."

"Xiao Mo, here, here, and here, have been completely controlled by us, and this is already wider and more vast than the land of Southern Tang and Western Qin combined. Not only can we cultivate food here, but it is also rich in minerals and resources, and we can get everything we need by driving a large number of slaves to work. ”

Liu Yi pointed to some places in the Americas, Australia and the South Seas.

"Xiao Mo, the royal families of the Southern Tang Dynasty and the Western Qin Dynasty are still dreaming of the Spring and Autumn Period in their cages, and our sons and daughters of the Han Dynasty have already squandered their blood all over the world, and they have conquered the alien race with the sword in their hands, so that the alien race can only crawl and tremble in themselves. Their swords had been turned into ploughs and hoes at this time, conquering, and reclamation, and the Southern Tang and Western Qin would never understand the benefits of this. ”

"Xiao Mo, do you still doubt our strength now, the background of the Great Han is far more than that, you have done paperwork on the Pingnan, you should have seen its speed. In the future, the sea ships of the Han Dynasty will have such speed. ”

"No, the Great Han's sea ship not only has such speed, but it will become like this, and it will be intimidating to all enemies."

Liu Yi pulled Chen Fang and came to a model of a sea ship, it was a metal model, with a sharp hull structure, a prominent battery position, a huge chimney on the ship, the paddle wheel had been completely abandoned, Chen Fang could think that its power was already the huge chemical energy of heavy oil combustion converted into the mechanical energy of the propeller.

Internal combustion engine propellers, steel megaships.

This is already an existence far beyond this era, such a navy, not to mention that Datang is powerless to stop it at all, and Western Qin does not have the slightest way to stop it.

If it weren't for the fact that artillery technology was still somewhat backward, such a warship would have been able to catch up with the ironclad ships of Europe in the nineteenth century.

Chen Fang's hand trembled unconsciously, Liu Yi grabbed his hand, pulled it gently, and let him caress the streamlined huge model hull, let his hand caress the sharp and slender hull, and finally, Liu Yi put Chen Fang's hand on the rows of hull holes.

"Your Highness, if you make a ship out of steel, won't it sink?"

Chen Fang deliberately asked randomly.

"No, it will crisscross the seas and terrify any enemy who dares to confront the Great Han, it will conquer all the coastal areas of the Southern Tang and Western Qin, and then cooperate with the army of the Great Han to completely take the Southern Tang and Western Qin into the possession of our Great Han."

"Xiao Mo, tomorrow I will take you to see some of the things shipped back from the Americas, you can feel our strength even more, I said that I want you to be the most noble man in this world except for the Han royal family, I will definitely do it."

Liu Yi chuckled, hugged Chen Fang, looked at him affectionately, and then grabbed his hand and put it on his face, letting him touch his cheek.

"Xiao Mo, it's late at night, let's rest!"

"Your Highness, can I stay here for a while?"

"Then I'll accompany you!"

Liu Yi accompanied Chen Fang to stand in front of the huge world map, and Chen Fang looked at the hand-drawn world map with a lot of emotion.

This ancestor of the Northern Han Dynasty, Liu Xiu, who is also a crosser with himself, is really not simple.

"By the way, Your Highness, just now you said that your ancestors left charts and notes, can I read the notes?"

"The notes are kept in the vaults of the palace, and no one is allowed to view them except for members of the royal family."

"Oh, Your Highness, Xiao Mo lost his words just now."

"It's okay, you'll be my colt in the future, and you'll be half a member of the royal family, but I really can't show you that note, but I do remember some of the notes in it."

"Then Xiao Mo can you listen to it, I'm very interested in these."
