Moreover, Yu Xiaotian sent people to build a large number of iron furnaces in the local area, smelt these coal and iron ores on the spot, and transport the finished iron ingots to Weitou Bay, and ship them to Taiwan Island for use by the industries that have begun to take shape on Taiwan Island.

In the next step, he has already made plans to build an earthen steel-making furnace directly in the Longyan area of Zhangzhou Prefecture, carry out steelmaking on the spot, transport the steel to Weitouwan, and set up a hydroelectric factory directly in the Quanzhou area to digest a part of the steel on the spot, so that the ordnance can be produced locally and directly delivered to the military for use.

For Yu Xiaotian's practices, the Fujian officials can only turn a blind eye, local officials, have the intention to stop, but they do not dare to speak lightly, individual gentry in order to Yu Xiaotian to occupy the land, forcibly annex the land from their hands, used to set up various workshops and workshops are very dissatisfied, some people launched a boycott, gathered some people everywhere, trying to get the official to prevent Yu Xiaotian from doing this.

But Yu Xiaotian is now completely unscrupulous, as long as he finds that someone is stumbling on him behind his back, it will not take a few days, this person's whole family will disappear inexplicably, or the leader will die inexplicably, using this method of knocking on the mountain and shaking the tiger, blocking the mouths of these people, in addition to the government, he is also willing to spend money, after dredging up and down, those who are officials have short hands and eat people's soft mouths, so they can only turn a blind eye.

Therefore, under the full promotion of Xiaotian, a large number of workshops have begun to appear in some coastal areas of Fujian, directly using local manpower and material resources to produce various industrial products.

At the end of the eighth year of Chongzhen, the first hydraulic workshop built by Seawolf Group was officially put into operation in the area of Houxi Town, Tong'an, Quanzhou, on the bank of Houxi.

This factory encircled hundreds of acres of land, covering a considerable area, it can almost be called a castle, completely closed management, no idle people are allowed to enter and leave without permission, and Yu Xiaotian sent a platoon of infantry to garrison, not far away, is the city of Gaopu, once it is disturbed, it can get support immediately.

This factory was built by Seawolf more than a year ago, and many people thought it was just a fort, but later when someone saw from afar inside the village, there were large sheds and a lot of unknown machinery and a few water turbines installed, and some people realized that this place would become a big workshop.

But the people who come in and out of here are all tight-lipped, and no one knows what is going to be produced here, and this workshop is actually the first arsenal set up by Seawolf on land, which is dedicated to producing all kinds of guns for the Yu army, which can be equipped for the use of the family army on the spot.

Yu Xiaotian kept a close eye on industrial matters, and since Sun Yuanhua arrived on the island of Taiwan, after obtaining Yu Xiaotian's mechanical principles, he devoted himself to this and began to have a strong interest in mechanics.

Even during the period when Yu Xiaotian led his troops south, Sun Yuanhua constantly asked people to send letters to Yu Xiaotian, asking Yu Xiaotian some questions about machinery in the letters, or discussing some academic problems about mathematics and geometry with Yu Xiaotian.

Although Sun Yuanhua started late, his starting point is much higher than that of Zhang Blacksmith, he has quite good basic knowledge of mathematics and physics, and many principles that Zhang Blacksmith does not understand can be easily solved in his hands, so Zhang Blacksmith is also very impressed by the knowledge of this new Mr. Sun, and he runs to Sun Yuanhua every day to ask for advice on various questions.

And Sun Yuanhua also asked Yu Xiaotian to find a way to get his three sons to the island of Taiwan, his three sons themselves followed Sun Yuanhua a lot of Western studies, in mathematics and geometry have made quite a lot of achievements, to the island of Taiwan, after seeing their father safe and sound, his three sons all volunteered to stay here, became Sun Yuanhua's right-hand man, and also became Sun Yuanhua's first batch of mechanical students.

In addition, Yu Xiaotian also selected more than 20 of the smartest students for Sun Yuanhua, all of whom were about eleven or twelve years old, all of whom were orphans, and specially followed Sun Yuanhua as a student to learn all kinds of Western studies, especially mechanical knowledge.

So don't look at the mechanization process of the Seawolf Group is still very rudimentary, but as long as these students are gradually cultivated, it will play an extremely important role in promoting China's industrialization process in the future.

Yu Xiaotian didn't plan to eat a fat man in one bite, and he would train as many engineers or mechanical experts as he did now, but what he had to do now was to plant some seeds first, let these seeds sprout and grow, and gradually blossom and disperse, so as to achieve a large number of scholars with specializations in the future.

Therefore, as long as he takes this step, then in the future, as long as he guides the style of study, no one can stop the pace of the industrialization process of the Chinese in the future, and sooner or later, China will become the world's first industrialized power.

In addition, considering that the next military operation will require a large amount of food and all kinds of mules and horses, after Yu Xiaotian returned to Waitou Bay, he immediately ordered an additional group of men and horses of the First Fleet, and two additional infantry battalions to be transported to Jeju Island, and completely controlled the entire Jeju Island by force, and completely assigned Jeju Island to his banner.

As for whether the Joseon Dynasty is happy or not, he doesn't care at all, anyway, Jeju Island is important to them, but they don't have the force to take it back, nominally they still temporarily retain the North Korean government on Jeju Island, and they should send them some bad horses every year, and also send them some bad horses, pay some taxes, nominally not completely cut Jeju Island away from the Joseon Dynasty, but in fact, it is equivalent to including the entire territory of Jeju Island into his jurisdiction.

After this military operation on Jeju Island, after taking inventory, the number of various horses on the island is as high as more than 30,000, and the number of cattle and sheep is also as high as tens of thousands, which can basically meet his needs to equip several cavalry battalions and baggage battalions, and can meet the mule and horse modification of several artillery battalions.

In addition, Yu Xiaotian also issued a new order to the one-eyed dragon, ordering him to immediately move south to the side of the Lê Dynasty in Vietnam after cleaning up the large number of pirates along the coast of Guangzhou, and capture the area around Ha Long Bay.

Hung Kai Port is 50 kilometers north of Haiphong, Vietnam, is the largest coalfield in Vietnam and even Southeast Asia, and the mining operation is simple, it can be fully open-pit mining, the quality of the coal produced is very good, the sulfur and phosphorus content are very low, the reserves are large, enough for him to mine for 200 years.

Although there are large coal reserves in Chinese mainland, Yu Xiaotian knows that Shanxi, Henan and other places contain a large number of coal mines, but the coal mining there is more difficult, and transportation is not easy, for a long time, I am afraid that it will not be possible to achieve large-scale mining.

However, the high-quality coal reserves in the south are not abundant, so he suddenly remembered that the area around the Hongji Port in the later generations of Vietnam is a super large coal field, and the quality of the coal produced is very good, and it is the most important coal export port in Vietnam.

And he has a natural hostility towards the black-skinned monkeys of Vietnam, like the Japanese, this small country, historically often disobeyed the jurisdiction of Chinese mainland, from time to time will fight with the imperial court on the mainland, and during the Song Dynasty, he even invaded the city of Nanning Massacre.

In the future, this small country will be in the South China Sea, and it will not be able to get along with China everywhere, and it will be a white-eyed wolf that cannot be fed by nature, so now that he has the strength, it doesn't hurt to beat them first.

Over the years, he has purchased a large number of Vietnamese monkey slaves from the pirates to engage in various basic development work on the island of Taiwan, and for these Vietnamese monkeys, he has never known mercy, as long as there is still a breath of air, he has to find a way to squeeze out their labor force, and if he can't do it, then the well-intentioned world will be ruined.

The pirates even kidnapped many Vietnamese women, many of whom were married to sea wolf generals, which solved many of his problems of imbalance between men and women.

Although the Vietnamese women of this era really don't fit his aesthetics, they are still very sought-after goods for those soldiers who can't find their wives because they can't find their wives, at least they can solve the problem of human desire!

In addition, the capture of Ha Long Bay, there is also an advantage, that is, you can directly obtain the local rice produced in Vietnam, Vietnam in this era because of the promotion of Champa rice, and a large number of land has also been occupied by some magnates, these Vietnamese Li Dynasty magnates, each family, less than thousands of acres of land, more than tens of thousands of acres of land,

Every year, the big estates of these magnates can squeeze the serfs at hand, cultivate the rice fields for them, and accumulate a large amount of rice, which they cannot eat and are reluctant to give to the serfs, so they will find a way to export and sell it.

Therefore, in the coastal area of the Beibu Gulf, a market town was specially formed, and many Chinese merchants started trading here, dumping the goods of the Ming Dynasty there, selling them to the Vietnamese, and then buying rice from the Vietnamese and transferring it to Guangdong and Fujian to sell and earn high profits.

In the eighth year of Chongzhen, although there was no great chaos in Liangguang and Fujian, but because of the lack of grain in the north, the national grain prices skyrocketed, and when it was the most expensive in Fujian, a stone of brown rice could only be sold for one or two halves, but at this time, the price of grain almost rose to more than two taels of silver.

However, the price of grain sold in Vietnam is only six or seven yuan of silver, which can buy one stone of rice, and 200,000 stone of rice is exported to the outside world every year.

Over the years, his hand has long been stretched out over there, and he has killed several groups of big grain merchants of the Ming Dynasty who are trying to compete with them at sea, almost monopolizing the grain exports there, and now the grain exported by the big households of the Li Dynasty is basically sold to the Sea Wolf Group, and is transported back to Taiwan Island or Weitou Bay by the Sea Wolf in ships for storage.
