In order to build more large ships faster and better, it has also led to machinery manufacturing, and the Nanjing Royal Machinery Factory has been established, in recent years, a steady stream of water conservancy machinery has begun to produce a variety of water conservancy machinery, these machines are not only used in the machinery manufacturing industry and the military industry, some woodworking machinery has also been manufactured, and has been continuously shipped to shipyards around the country and put into use.

In addition, the shipbuilding industry has also absorbed a considerable number of idle people, and initially formed a large number of industrial workers, which is particularly important for China to complete industrialization and capitalization development in the future.

The most important thing is the revival of the shipbuilding industry, which has led to more and more Chinese ships appearing on the oceans, and Chinese ships have begun to sail further from Manila in the Philippines or as far as Batavia or Hirado and Ryukyu in Japan.

By the seventh year of the Yuan Dynasty, the newly launched Western-style sailing ships of the Great China and North Koreas were no longer inferior to those ships of Western countries, and they could sail into the Indian Ocean, and even appeared on the coast of Africa.

Although the opening of the sea ban by China, China and North Korea was good news for businessmen from Western countries such as the Netherlands, Spain, Portugal, and even Britain and even Venice, it also made them feel the threat brought to them by the great power of the East.

In the past, when these ships from Western countries came to the coast of China, they repeatedly tried to forcibly occupy a piece of land as a base for their business, and when they could not negotiate with the Ming Dynasty, they simply robbed and robbed Chinese merchant ships at sea.

Anyway, in their eyes, the Chinese's sea ships are small and thin, and the speed is slow, they can do whatever they want, and they live a life of thieves and merchants at sea, and they disdainfully call all Chinese ships kron, which means waste.

However, after the fourth year of the Dazhong Dynasty, they began to find that the Dazhong Dynasty also began to appear sailing ships similar to their Western ships, that is, the Galen ship type that they commonly used, and these ships began to be loaded with more and more guns, and began to become less easy to deal with.

By the seventh year of Tianyuan, these Galen ships built by the Chinese themselves became larger and larger, and in addition to absorbing the shipbuilding technology of Western sailing ships, they also began to effectively combine many shipbuilding technologies of the Chinese to make them more suitable for navigation, and the number of them made these Westerners begin to smack.

In particular, the warships of the Royal Navy of China, China and North Korea began to be refitted into new-style warships in large numbers, and began to cruise along the coast of China and even in the South Seas, inspecting and intercepting those ships that tried to smuggle, and began to become the masters of this Chinese sea.

Previously, in the early years of the Ming Dynasty and the Great Middle Dynasty, the Chinese warships generally did not easily penetrate into the deep sea, and even if they clashed with Westerners' ships, the Chinese could only rely on numerical superiority to suppress Westerners' ships.

However, after the introduction of Western sailing ship manufacturing technology in Dazhong and North Korea, and began large-scale construction, this situation began to change, more and more Chinese warships began to enter the deeper and deeper sea in small formations for cruising and training, and strengthened the control and patrol of the coastal islands, and even in the later period, a kind of fast single-sloopted double-dronged fast patrol ships began to appear quickly, and they appeared alone in the waters where the sea division rarely appeared before, Cruising and hunting down pirates has become the master of the sea.

The rapid rise of the Chinese's naval division power greatly exceeded the expectations of the Westerners, and they did not realize until this time that this era had changed, and now this great Chinese dynasty in the east is completely different from the previous slow and numb Daming Dynasty, they began to become more good at learning, more confident, more expansive and even aggressive, their actions greatly reduced the pirate force in the South Seas, and began to extend their tentacles farther.

The Spaniards even found that in the Philippine Islands, there were more and more Chinese warships, they were constantly surveying the islands and shipping lanes here, drawing maps and charts of this area, some islands that the Spanish failed to occupy, also began to appear Chinese, and even the Malay Archipelago further south began to be touched by the ships of the Chinese maritime division.

The Spanish ships had even encountered warships with Chinese naval divisions hanging high outside the port of Manila, so the Spanish asked why the Chinese came here, but received an arrogant answer, the Chinese naval division personnel said that they were chasing pirates, and the Spanish were not allowed to interfere with their actions, otherwise it would be a challenge to the Chinese navy.

The Spaniards were horrified to find that the warships of the Chinese Navy at this time were no longer the kind of Kron ships that they had despised before, but had been replaced by large three-masted Galen ships, which, like their ships, were covered with gun doors and rows of naval guns with black holes in their muzzles.

Moreover, these Chinese warships began to become larger and larger, and gradually began to be comparable to the large warships of the West, and at this time, they began to realize that the South Seas were likely to become an inland sea for the Chinese.

Because their country is far away, whether it is the declining Portuguese or the Spaniards, or even the Dutch, who are known as the sea coachmen, it is impossible to send a large number of warships to the far east, and at this time, the sudden outbreak of sea power by the Chinese makes them undoubtedly and quickly become the overlords of this distant eastern sea.

The Spaniards and Dutch had been free to intercept Chinese merchant ships at sea and force them to trade in their ports, but now they found out how stupid it was to do so, and the Chinese began to become short-guarded, and once they learned that their Chinese ships were under such an attack, their naval warships would go to the place of the accident to protect their merchant ships.

This is not the worst thing, with China also established a maritime trade group company, the Chinese merchant ships, also began to gradually appear some large Galen ships, although these ships are used as merchant ships, but the armament on the ship is not weak at all, also loaded with a large number of cannons, can also be used as war ships at any time, so that these Western ships on the sea, can no longer as before, wantonly intercept the Chinese merchant ships, and even they have to avoid these merchant ships, so as to avoid conflict.

China, in the eyes of Westerners, a huge country, once the way of thinking changed, the power that erupted is unimaginable to Westerners, China has too many ports along the coast, and they have an inexhaustible manpower, in addition they can recruit a large number of sailors at any time, once they set their eyes on the sea, the strength of the burst, so that these European maritime powers can only look sideways, they realize that in the East, began to appear a strong opponent that they feared.

At this time, Macao is no longer a prosperous market because of China's open sea ban, the Chinese clearly expressed their attitude, not allowing Chinese merchants to go to Macao to trade with the Portuguese, but instead to open more than ten commercial ports along the coast, as the port of China's maritime trade, then Macao will lose its previous advantages, there is no business to do the Portuguese can only gradually withdraw from Macau, I believe that soon, the Chinese will take back Macau, the Portuguese will be expelled from here.

The Dutch and Spaniards are probably the most disturbing now! In the sixth year of the Tianyuan Dynasty, just after the end of their Liaodong expedition, the Chinese court made clear representations to the Dutch, indicating that they had sovereignty over the island of Taiwan, and informing the Dutch that they must withdraw from the island as soon as possible, otherwise, the next step will be to take military action at any time to recover the island of Taiwan.

For this reason, of course, the Dutch refused to spit out this piece of fat at the entrance, and made representations to the Dazhong Dynasty through the Jesuits, claiming that they had obtained the permission of the Ming Dynasty, the former dynasty of China, to settle on the island of Taiwan, and that the Dazhong Dynasty could not expel them from the island, and wanted to continue to entrench themselves on the island of Taiwan by playing scoundrels.

However, the officials of the DPRK directly rejected their demands, ordering them to evacuate as soon as possible and demolish their forts and castles on the island of Taiwan, as well as the fort castles around the chicken coop, otherwise the DPRK would take unilateral action to take back the island of Taiwan.

The tough attitude of the Great China and North Korea made the Dutch nervous, because they had realized that the sea power of the Chinese was no longer what it used to be, and if the Chinese wanted to take military action, they would have no chance of winning.

But let them spit out this piece of fat like this, and the Dutch are not reconciled, you must know that they regard the island of Taiwan as a very good cow, and here among the twenty-five trading houses of the Dutch in Asia, the profits handed over every year are ranked second, on average, there are 400,000 guilders every year, and the value reaches four guilders of gold, so they will not agree to withdraw like this.

The Dutch began to make intensive preparations, and they appealed to the Dutch East India Company for help, for which the Dutch East India Company reinforced Taiwan with 1,200 soldiers and dispatched more than 20 armed ships to patrol the coast of Taiwan.

In September of the seventh year of the Yuan Dynasty, Chinese fast sailing ships began to appear off the coast of Dayuan, Taiwan, and began to reconnoiter the arrangement of the Dutch in the Dayuan area.

When the Dutch discovered these scout ships of the Chinese naval division, they immediately sent ships out to sea to try to expel the Chinese scout ships, and friction began to arise between the two sides, and there was an exchange of fire at sea.

At the end of September, the DPRK officially declared the Dutch persona non grata, forbade Chinese merchants from engaging in commercial trade with the Dutch, and ordered the Haimao Group to stop all commercial contacts with the Dutch, stop all merchant ships going to Taiwan and the ports of Batavia, and declare that China and the Netherlands would become hostile countries.

In early October, Xiao Tianjian summoned the military department and naval attachés at the Wuying Hall in Beijing, listened to their war plans for the recovery of Taiwan Island, and personally watched the navy's war rehearsal in the main hall.

The Southern Fleet drew up a detailed battle plan, which included the deployment of Chinese forces, as well as the deployment of the Dutch on the island of Taiwan, as well as their battle plans.

Xiao Tianjian personally examined and approved the battle plan submitted by the Ministry of War and the Navy, and finally Zhu Bi signed and approved their battle plan, and then the operation to recover the island of Taiwan began to be implemented.
