Li Shimin also agrees with Li Jing's judgment.

Therefore, I am more cautious about this sea strategy.

It is to follow the old road to create a century-old prosperous era that shines in China.

It is still to reverse the situation of the national policy of laying out the millennium in advance.

This is not his merit alone, but is linked to the well-being of tens of millions of people, so he has to be cautious.

Therefore, it can be said that it is the huge archipelago group and abundant products in the South China Sea that make it difficult for Chinese ships to sail in the open sea.

This is because they are basically navigating the interior of the archipelago, and the coastal trade within the archipelago is basically a complex and changeable nearshore wind.

The nearshore wind is complex and changeable, so the Chinese ship is racing all the way on the scientific and technological point of the longitudinal sail.

Reefs are often a problem to be taken into account in coastal trade, so the technology of watertight compartments has been advancing.

As a result, the sail suitable for monsoon ocean navigation does not invest too many scientific and technological points, after all, there is no need for research?

The problem of sea ships has become very complicated by the Ming Dynasty, and the most prominent problem is the sea ban.

The policy of sea ban was not invented by the Ming Dynasty, but learned from the Yuan, and the Yuan was learned from the Song Dynasty.

The reason for the ban on the sea in the Song Dynasty is also very simple: it's all my money! Labor and management must be monopolized!

In this regard, a certain Song Dynasty emperor Wan Yan, who did not want to leave his name, summed it up very clearly:

"The profits of the market are the greatest, and the income is millions, is it not better than the people? Therefore, I pay attention to this, and I can be less lenient for the people. ”

Let's not say this sentence for the time being, put a few catties of gold dust on my face, but I do have a very good understanding of the profits of marine trade.

The sea ban in the Song Dynasty was not abolished until the Shenzong period, and in the Southern Song Dynasty, Gaozong reopened the sea ban and continued until the death of the country, with a total of 252 years of sea ban.

The Yuan Dynasty itself was short, although it tried the official ship system of renting official ships, but it soon failed, and there were four sea bans before and after, adding up to 19 years.

The Ming Dynasty learned the lessons of the Song and Yuan dynasties - because when the Southern Song Dynasty fell, the Semu people of Quanzhou surrendered to the Yuan under the leadership of the leader Pu Shougeng and killed the Southern Song clan and officials.

This kind of backhand knife really opened the eyes of the later emperor.

Because of the lessons of the previous dynasty, as well as the rebellion of Zhang Shicheng in the early Ming Dynasty, and the invasion of Japanese pirates in the later period, the severity of the maritime ban was gradually strengthened, and finally lasted for 197 years.

And the entire hundreds of years of history in the south of the Ming Dynasty is just one sentence, and the Ming official and maritime groups did not pee into a pot on the issue of interests.

As a result, Emperor Yongle directly threw off the maritime merchants and went it alone, from the upstream production source Weaving Bureau, ceramic town, tea garden, to the downstream Zheng He went to the West to deliver door-to-door tailor-made, all in the hands of the emperor alone.

This attitude completely intensified the contradictions between the maritime merchants and the government, which led to the direct one-size-fits-all ban on the sea by the Ming civil official group, but what should the maritime merchants do in the name of the Japanese and the Ming Dynasty was completely embarrassed.

On the issue of the sea, if they want to develop warships, seize sea power, and build naval divisions, these are all things that maritime merchants cannot accomplish.

And on the issue of the ocean, the Ming Dynasty was missing one of its most important legs: mathematics was removed from the imperial examinations, leading to a near stagnation in its development.

This leg could have been made up for through the cultural exchange of the maritime trade route, but in the end, it was two hundred years after the sea was opened, and Xu Guangqi started from scratch, even if he was tired and vomited blood to make up for Daming's leg, it would be too late.

In fact, the navigators of the Ming Dynasty also saw the Galen ship that came across the sea, and from our current point of view, the Galen ship can be called the pinnacle of ship design in the 16th century.

This advanced sea ship also brought a great shock to the Ming Dynasty, which also imitated the Galen ship and absorbed its advantages to improve the Chinese ship.

However, the core idea is still to be used for trade between the islands in the South China Sea, and there is no idea of going to the ocean.

The Galen's iconic keel rib hull, soft sails, and mast sails can all be seen in the shipbuilding records of the Ming Dynasty.

After the fall of the Ming Dynasty, the Qing Dynasty went one step further on the basis of the sea ban and directly began to close the country.

In the end, during the Opium War, Britain defeated the Qing government with 800,000 troops with 28 Galen ships and less than 20,000 troops.

It completely opened a chapter in modern history. 】

Seeing the structural diagram of the huge ship, Yan Lide dragged his younger brother and violently knocked away the Guogong in front of him, and then raised his head and grabbed a table casually.

A large piece of white paper was spread on the table, Yan Lide just exchanged a look with his younger brother, and the two of them copied on this white paper at the same time.

The structure of this Galen ship is huge and complex, and Yan Lide understands that he can't finish the plan on his own, but fortunately, he still has a younger brother.

It was not the first time that they had painted Danqing together, and the two brothers knew what they were good at each other, so after hastily sketching out an outline, the two of them quickly raised their heads and lowered their heads to add something to the picture.

And the more he copied it, the more Yan Lide felt that the sea master of the Tang Dynasty still had a long way to go.

Unlike the previous horseshoe, you can see the effect at a glance, and unlike the gunpowder, you only need to concentrate on research for three or five months to make a breakthrough.

The composition of this Galen ship is really a copy, why is it this structure that is narrow at the top and wide at the bottom? How do you dispatch so many sails? How to control the stern of the ship?

Especially what does the inside of this hull look like? At this time, Yan Lide's mentality was a little crazy, and he couldn't wait to get into the light curtain and pull the collar of the junior and roar:

There are two diagrams, how about you add an inner structure diagram?

But in the process of copying, Yan Lide also quickly calmed down, if you calculate the time, this is a ship thousands of years later, it is a blessing to be able to get a glimpse of it, how can you ask for more?

And even if you only look at the appearance, there is at least the possibility of imitation, unlike the "Dongfeng Express", from take-off to shuttle patrol to explosion, in which the doorway can not be glimpsed.

Besides, this Galen ship does not necessarily need to be completely imitated, as long as it can figure out why the form of this ship is designed like this, it will be of great benefit to Datang Shipbuilding.

Li Shimin looked at the busy Yan brothers and was very pleased, I Tang has a handsome talent, the craftsman can pass the spirit, and the danqing can carry the Tao, neither of which is a small way.

The Yan brothers were in a hurry, so some of the drawing paper was scattered on the ground at the original painting table.

Li Shimin leaned over and picked it up and was about to put it neatly when he saw the contents of the drawing paper, and an emperor was laughing on the couch.

The face is lifelike, and the emotional power of the characters is through the back of the paper, if you ignore the face on the painting paper that is nine points similar to yourself, Li Shimin probably still appreciates it very much.

But......

Glancing at the Yan brothers who were eager to grow one more hand, Li Shimin quietly put the piece of drawing paper into his sleeve and turned it back to the couch.

And in front, Fang Xuanling was still discussing with Du Ruhui in a low voice:

"According to the Hereafter...... Isn't this rebellion of the people of color the dark thunder that my Tang left to this Song? ”

Du Ruhui stroked his beard and whispered;

"In the matter of the management of foreign clans, I and Tang do not have the practice of the previous dynasty to evolve, and there must be omissions in the process."

"From this point of view, if you encounter problems that were not in the previous dynasty, you need to be cautious."

Fang Xuanling also added: "The decree also needs to leave room for correction." ”

However, after Fang Xuanling added it, he was also quite moved by this Song Zhi's evaluation:

"There is a lot of turmoil in this Song Dynasty indemnity, but it can also continue for hundreds of years, but it is because of this sea trade profiteering?"

He wanted to say that "it was very profitable", but when he thought that this trade was enough to feed a country, this wealth could only be described as windfall profits.

And then the sea ban of the Song, Yuan, and Ming dynasties was repeated and gradually severed, which was not too surprising to Fang Du and the others.

From the time they knew about the 50-day-old Champa rice, the two recalled the rebellion between the Wei and Jin dynasties and the Northern and Southern Dynasties, and they were keenly aware that the gap between the wealth of the north and the south would only get bigger and bigger.

After all, the north not only has to face the Zhuhu outside, but also has to face the internal military rebellion of the Huaxia Dynasty, and every time the Central Plains is almost destroyed.

In the south, there is a granary of rice that crops once every two months, and there is a maritime road to replenish wealth, and there is no enemy outside but no chaos inside.

The number is uneven, the rich and the poor are different, the people are different, how can the suspicion not be born?

The two looked at each other and sighed together.

Now the wider my horizons, the more sorrowful I have.

Regarding the contradiction between the central government of the Ming Dynasty and the maritime merchants, Li Shimin grinned:

"In this Ming Dynasty, if there is an invincible army on the sea, this maritime merchant dares to say more?"

The internal situation may be very complicated, but Li Shimin stood aside and looked at it, feeling that this problem was essentially the same as cracking down on Haoqiang.

If you are strong and strong, then you are all good citizens who pay taxes obediently.

If you have few soldiers and weak horses, then you will be a strong man who does not obey discipline.

Wei Zheng looked at the achievements of the Ming Qing in later generations, and was slightly confused:

"The edge of this ship is so sharp? 20,000 against 800,000? ”

The generals present were not surprised, Li Shichang explained:

"This army of 800,000 just sounds bluffing, and even if there really is an army of 800,000, it will not be able to merge in one place."

"On the contrary, it is this British ship, but it can attack Guangzhou today, enter Hedong tomorrow, and come to Quanzhou the day after tomorrow."

"Suddenly, take advantage of the sail to attack the labor, when the strong is escaped, when the weak is attacked, the attack must be defended, and then the attack is not prepared, how not to win?"

Wei Zheng was silent.

……

Chengdu Mansion, Zhang Fei is a little hard to imagine:

"Can this maritime road really be so rich?"

Kong Ming smiled:

"How did Wing Der forget how the Rest Empire flourished?"

So Zhang Fei remembered:

"Controlling the Silk Road ......"

Kong Ming nodded:

"The Silk Road can feed a vast empire, so why is it difficult for the Maritime Trade Road to feed a country?"

And in his heart, Kong Ming can also list several advantages of sea trade.

For example, ships are better than horses and camels.

For example, there is no need to travel by sea like the Silk Road in the Western Regions.

For example, if it is downwind, it is much faster than on land.

The only problem is that after the prosperity of maritime trade, there will inevitably be piracy, but if it is considered as a net profit, it is still far more than the land route.

For a while, Kong Ming sighed a little: How good would it be if Jiaozhou was all smooth roads?

In that case, after Ke Fu Hanzhong, he will go to take Jiaozhou, and then build sea ships to prosper sea trade.

Unlike now, seaports are hard to find.

My heart was full of sighs, but my hands didn't stop for a moment.

While using charcoal and a ruler to try his best to draw the map of the Galen ship on the light curtain, he still had time to instruct Pang Tong and Liu Ba, who were not good at Danqing, to rub the map into their minds, and later check and fill in the gaps in the drawing.

There is even time to deal with Liu Bei's questions:

"Kong Ming, should this sea ban be enforced?"

The charcoal pen in his hand swirled an arc, and at the same time Kong Ming replied:

"What is a sea ban? The lord was confused at this time. ”

"Maritime merchants do not have the sharp weapon of the sextant, and if they do not sail along the coast, they are in danger of getting lost, and there are many checkpoints that can be set up at sea."

"There should be borders on land, and there should be customs on the sea."
