Originally, in order for this thing to survive, the water quality required to be excellent, but in this era, the water quality is not bad anywhere on the earth, and there is no such thing as pollution. The water quality problem is very easy to solve, so as long as this thing goes anywhere, it can basically survive and thrive.

Through these two new species, Chen Fang has come to realize that the overseas trade of the Northern Han Dynasty was much busier than previously thought, and that there were ships sailing in the coastal waters of China, otherwise these species would not have traveled elsewhere.

Thinking that there were Northern Han ships sailing off the coast of Datang, and not once or twice, but often, Datang didn't know about it, and Chen Fang also had to sigh at the relaxation of Datang's coastal defense.

But this is also something that cannot be helped, the coastal defense of this era is basically like this, and there is no radar of later generations, and ships sailing a few nautical miles or even a dozen nautical miles away, who knows it.

Chen Fang also guessed that there were Northern Han ships that often crossed the coastal waters of the Tang Dynasty based on the reproduction of new species.

Otherwise, he wouldn't know!

Species involvement, on the one hand, is natural causes, and man-made, and for marine species, human activities are very likely to cause species involvement, of course, this is divided into intentional and unintentional.

At this time, it seems that the appearance of king crab and gooseneck barnacles is mostly unintentional, so the frequency of shipping in the Northern Han Dynasty can also be seen.

At this time, the little couple got a piece of broken silver, and the little trader was in a hurry, Chen Fang looked at him and pointed at him.

"These are the two things you just said about the strange things that happened on the beach, right?"

"No, it's a large shellfish, you haven't seen it, it looks like a man."

"Where?"

The wife of the young couple asked, obviously curious.

"What your husband has, you don't."

The little daughter-in-law blushed instantly, and she didn't know that the little trader was talking about men before.

, Chen Fang almost scolded, geoduck, I didn't expect this thing to really appear on the coast of China.

This is something from the Americas, which appeared on the coast of China at this time, naturally because of shipping.

It seems that the marine activities of the Northern Han Dynasty have caused the migration of a large number of marine organisms. On the one hand, this shows the frequent activities of the ocean, and on the other hand, it also shows that Chen Fang can really eat geoduck.

Before, Chen Fang wanted to take Wu Meiniang and them to the beach to eat oysters and geoducks, but in fact, he knew that there was no such thing along the coast of China, and the origin of this thing was not in China.

I didn't expect it to be there at this time, and the amount is considerable, otherwise the fishermen would not have caught it, it is really a scarce stock, where is it so easy to find and catch.

And geoduck is not easy to catch, in later generations to catch this thing with a high-pressure water gun, at this time can be caught, you can imagine how much this thing has multiplied.

You must know that the coastal fishery at this time is still in the most primitive state, and it is completely fished by manpower. There are only a few small fishing boats, and the far sea area is not easy to go.

This can be caught and caught, which shows that these species are not uncommon along the coast of China.

But whenever these things are discovered, they actually have a certain quantitative basis.

Chen Fang talked to the three of them for a while, and sent out a lot of broken silver, and everyone naturally talked happily with each other, and the three of them thanked each other for their kindness. In fact, to be honest, the information Chen Fang got from them was not something that could be measured by a few taels of silver.

At this time, he said goodbye to the three of them, and then returned to Wu Meiniang's side.

"What's wrong, Chen Fang?"

"It's nothing, Mei Niang, this time I went to the beach, I invited you to eat something good."

The ship has docked on the south bank, and the dock here is also busy, Wu Meiniang and her party went ashore, which naturally attracted countless eyes, this group of people is already dressed luxuriously, and it is even more rare that this group of people look superb, of course, the maid is superior, and it cannot be called the best.

There was a carriage and horse shop near the wharf, hired a carriage, said where to go, and the group got into the carriage.

There Wu Meiniang beckoned to Chen Fang, Chen Fang went to Wu Meiniang's side, the carriage began to move, the destination was Taihu Lake, in fact, it may not be possible to arrive that day, even if it arrives, it is very late.

As soon as Chen Fang got into Wu Meiniang's carriage, he saw Wu Meiniang grab his hand and pull him into his arms.

"Something is wrong with your face on the boat, what's wrong?"

"Mother, it's nothing, but I've heard a lot of strange things on the beach, and I think we can see a lot of strange things when we go to the beach this time, and I think it's funny. Niangniang has lived in Yangzhou before, has she ever been to the beach? ”

Wu Meiniang shook her head, in this era, the area is closed, and she lives near the coast, and there are many people who have never seen the sea. In later generations, there were not a few inland residents who had seen the sea.

Chen Fang didn't tell Wu Meiniang about his worries, because it involved the set of things that would be called the Great Geographical Discovery in later generations, and explained it to Wu Meiniang. I don't want to talk about it, and I can't explain how I know.

Still don't say it, it will only increase the trouble, and it will also make people wonder about themselves, which side is not cost-effective.

In the end, these things can only be buried in their hearts.

Chen Fang thought about it at this time, in the end, it was still the early advantage of crossing, looking at the Northern Han Dynasty, he had already begun to pass through the Americas and Australia, and the people of the Tang Dynasty did not know that there were these two continents.

That's the gap! The two continents support the Northern Han, and the strength of the Northern Han is becoming more and more difficult for Chen Fang to guess.

There, Wu Meiniang's hand gently caressed Chen Fang's palm, and then let that palm taste his soft body, Chen Fang stroked the landscape, but he didn't have much thought at this time.

Suddenly, Chen Fang was shocked to realize that something was about the Northern Han Dynasty.

Maritime, Nautical, Marine.

If the ocean-going shipping of the Northern Han Dynasty was really very frequent, then to what extent were their ships, especially those that crossed the sea between continents, advanced?

You must know that intercontinental shipping is not something that small ships can carry, and large ships have extremely high requirements for shipbuilding technology.

In the Age of Discovery, it was the time of the Ming and Qing dynasties in China, could it be that the shipbuilding industry of the Northern Han Dynasty at this time had made the Tang Dynasty and the Western Qin Dynasty look up.

There are also many things involved in shipping, such as the understanding of waterways, the understanding of the marine climate, and the understanding of the direction of the ocean winds in each season.

There are many more, such as ocean currents, turbulences, seasonal winds, and so on. At this time, Chen Fang realized that he had underestimated the former traverser, the one who crossed into Liu Xiu, and he couldn't be a navigator, otherwise why the Northern Han Dynasty focused on the exploration and conquest of the New World.

As for the Northern Han who almost died, probably just because he first came to this world, he was a little uncomfortable!

Traversers, as expected, there is no simple one, and the future generations will pull out a person casually. His thoughts and opinions are far from being comparable to those of this era, after all, he has received nine years of compulsory education, has been exposed to modern commodity logistics management, as well as modern industrial and military development.
