Under Jiang Chen's words, Da Song began to act, and at this moment, in the chat group, Jiang Chen was still talking.

"Los Angeles, no, at this moment it should be called a new seal, a new opening.

After more than half a year of construction, the new seal at this moment has begun to see the scale, one after another houses have risen from the ground, and the surrounding area has been completely emptied.

A large number of trees have been cut down, and there are crystal ears of rice dotted in the fields on the rice fields, and it can be expected that this year will be a bumper harvest year, which makes the Great Song Dynasty monarchs and ministers who have been running for a long time can't help but smile knowingly.

At this moment, there seems to be hope in their lives again, and they are no longer the kind of confusion above the ocean.

And in the city, at this moment, there are some more dark-skinned figures.

There is not much difference between the appearance and the Song people, but they are not Song people.

And these people are acting as the manual work of the entire new seal.

Zhang Shijie's cleaning not only cleared the danger around the entire new seal, but also provided enough labor for the new seal.

The pace of construction, which had been slow, has suddenly accelerated a lot, and even the development of farmland outside the city has become much easier.

And not only that, a large number of Indian women were assigned to the guards, as well as the single Song people, so that new families began to be born.

The population of the new seal has gradually approached 200,000 from more than 100,000.

But that's not enough.

At this moment, the center of the new seal is in a relatively gorgeous room.

Lu Xiufu, Zhang Shijie, and the little emperor gathered again.

At this moment, Lu Xiufu and Zhang Shijie were listening carefully to the little emperor's narration.

"Two teachers, Mr. said that this method should not make the number of natives exceed the number of Han Chinese, and the ratio should not be higher than five to one, and in the case of sea ships, Mr. said that there is a tree called "white oak" in the Americas that can be used as sea ships, and he also gave new shipbuilding drawings. ”

The little emperor spoke, and then turned his right hand, and a white light appeared, and then a thick book appeared directly in his hand.

"White oak?"

"New drawings?"

Listening to the little emperor's narration, Lu Xiufu and Zhang Shijie looked happy, and then couldn't help but look at the book in Zhao Yu's hand.

They had obtained the blueprints of the treasure ship from Zhu Di before, and they couldn't help but be shocked by such a huge treasure ship, but they didn't expect Mr. to give the drawings again, which made them a little curious.

As for the number of natives that Jiang Chen said earlier, the number of natives cannot be excessive, Lu Xiufu and Zhang Shijie naturally know it.

Such a lesson has appeared countless times in history, and Lu Xiufu and Zhang Shijie naturally will not make this kind of mistake.

Curiosity spread, and Lu Xiufu subconsciously took the drawings.

And when his gaze only fell on the drawings, Lu Xiufu's eyes suddenly widened, and his expression was incredulous.

"So fast!"

Muttered to himself, Lu Xiufu with disbelief.

"What's the matter, Lord Lu?"

Zhang Shijie was a little puzzled, and he couldn't help but be curious, so he leaned his head over, and at this look, Zhang Shijie's pupils widened.

Of course, it is not just the two of them who are surprised at this moment.

On the other side, in the Taihe Palace, Zhu Di, who was originally just subconsciously receiving, couldn't help but raise his head instantly, his eyes filled with disbelief.

And at this moment, in the chat group, Jiang Chen's words continued.

"There is no need for the Great Song Dynasty to build a treasure ship, it is too time-consuming, and it is not of much help to cross the ocean, it is better to build a flying scissor sailing ship directly, I will find it!"

"Found it, I'll send it to you."

"This type of ship has a small freeboard, less superstructure, which not only improves the stability of the ship, but also allows it to fully play the role of the sail. The ship is almost close to the water surface sailing, the length-to-width ratio is generally greater than 6:1, and its underwater shape is designed to minimize the resistance to improve the speed, but maintain a certain lateral resistance profile, resulting in a particularly beautiful waterline, and even in the first waterline surface has a concave, long and sharp curve scissor-shaped head column is a suitable for the running situation, in the sea can split the waves to reduce the wave resistance, so it is called flying shear. ”

"Before the advent of steamships, this kind of ship was widely used at high speed, with a maximum speed of 21 knots, even if the average speed exceeded 12 knots, it was the fastest sailing ship in history, and it was indispensable for the Song and Ming Dynasty to develop the sea."

"By the way, to explain, the speed of a section is most likely more than four miles every half an hour!"

"At such a speed, combined with the poison of Meng Yuan in the land of China, it is completely possible to block Meng Yuan while immigrating, and just wait for the sky to change, and the Great Song Dynasty can expel the Tartars and restore China."

Lines of text were typing rapidly.

While chatting about the lack of people in the Great Song Dynasty, Jiang Chen's ghost envoy sent the gods to talk about the sea boat.

After all, if you want to build a maritime civilization, sea ships are indispensable, although the Ming Dynasty has treasure ships, but treasure ships have great advantages, but also have disadvantages, that is, the speed is not fast enough.

Like a treasure ship of a castle on the sea, if you want to be fast, you can only depend on things such as wind speed and ocean currents, and such a speed is obviously not enough.

And the Great Song Dynasty is even more needless to say, if the Great Song Dynasty really ran to the Americas, then a suitable sea ship is a must.

And what kind of sea ship is the most suitable, there is no doubt that there is only a flying scissor sailboat.

As the last afterglow of the steam era, the flying scissor sailboat can bloom with his unique brilliance, let alone in the Great Song Dynasty and the Ming Dynasty.

Once the Great Song Dynasty and the Ming Dynasty had such a sea ship, this sea ship alone was enough to establish an unprecedented sea empire.

After all, it is unimaginable that a ship with a short construction period and a fast enough speed can generate value.

Not to mention the rest, if the Great Song Dynasty had a flying scissor sailboat, it could rely on the Americas to develop a base, and then immigrate from Mengyuan in a steady stream.

To a certain extent, an island chain can also be formed to directly block Mengyuan.

Although Meng Yuan didn't need to care about the sea, he couldn't resist the Great Song Dynasty and could attack from any part of the long coastline at that time.

Waiting for Kublai Khan's death, it is impossible for the few wastes of the follow-up Meng Yuan to stop the people of the Great Song Dynasty.

And more importantly, the migration of a large number of people to the Americas is enough to make the Chinese classical civilization retain more, and its significance is unimaginable.

In the room, the more Jiang Chen spoke, the more energetic he became, and his eyes couldn't help but bring a look of excitement, as if he had really changed everything at this moment, and he was really manipulating the changes in Da Song with his own hands.

It can't be helped, it's exciting to think about it, let alone describe it yourself.

So much so that he couldn't help but stop eating.
