But Yu Xiaotian didn't be happy for long, only three days later, the boiler of this steam engine exploded in operation, killing a boiler worker on the spot and injuring several skilled workers, which made many people fear this terrible machine. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

But Yu Xiaotian didn't think so, and still made an order to continue to improve and develop this kind of machine, no problem how much money it spent, as long as this kind of machine is improved to be safer and the output power is greater.

And in the following more than a year, Yu Xiaotian personally went to the Shunde State-owned Machinery Factory many times, personally led the technicians and some technicians, including the experts of the newly established Mechanical Research Department of the Chinese Academy of Sciences, and constantly made various improvements to the steam engine and carried out tests.

The early steam engine often had accidents, they continued to look for the cause, to improve, and the original steam engine because of the design or materials or processing problems, the structure is simple and rough, the failure rate is high, the output power is small, Yu Xiaotian also personally attended, with technical personnel, put forward a lot of eye-catching improvement suggestions, try their best to improve.

After more than a year down, a total of more than 10 experimental steam engines were manufactured, and finally in the summer of the eighth year of Chengtian, a formal mass-produced steam engine was finally finalized, and the test was successful, and the trial operation was insisted on for a month, so that the steam engine was successfully finalized, and was ordered by Yu Xiaotian, and began to be put into production in large quantities, which was used for the mechanical production of various machinery factories and arsenals, as the driving force.

In this way, the machinery industry of the Great China and North Korea has completely shaken off the shackles of relying on water power or sharpness to provide power to the factory, so that in many places, there is not enough water to provide power for the factory, relying on the steam engine, it can provide a steady stream of power output for the factory, which greatly promotes the process of industrialization.

History says that from this year, the Great and Middle Korea completely entered the era of steam engines.

At the end of the eighth year of Chengtian, a large fleet was assembled again in Hong Kong, and this time this fleet gathered a total of nearly 100 large sea vessels, including huge Galen ships and elegant clippers, loaded with a large amount of food and fresh water, as well as more than 20,000 sailors and sailors.

Emperor Chengtian Yu Xiaotian traveled thousands of miles, personally rushed to Hong Kong, participated in the expedition ceremony, this fleet is a standard ocean-going fleet, the destination is not Malacca, their mission on this trip, is to cross the entire Pacific Ocean, to North America New Spain, that is, Mexico in the future, to conquer there, the Spaniards entrenched there for decades, completely drive away from there, occupy the local silver mines, of course, the territory of the United States in later generations, by the way, Xiaotian has been assigned to the territory of Dazhong in advance.

And the commander of the fleet this time is his brother Luo Xianbin, who started with him back then, and now Luo Xianbin has become the deputy commander of the South China Sea Fleet, and was appointed by Yu Xiaotian to become the commander-in-chief of this expeditionary force.

What makes everyone in the fleet even more proud is that there are two other people who also go out with the fleet this time, they are Yu Zhenshan, the great prince of the current Shengshang's knees, this time officially as the commander-in-chief of the landing combat force and the deputy commander-in-chief of the fleet.

The other is Yu Zhenyang, the second prince of the saint, but his position is relatively low, he is only the deputy captain of a main battleship, and his status is much lower than that of the eldest prince Yu Zhenshan.

However, the second prince is considered to be a serious man from the navy, but he is the twelfth graduate of the naval academy, and has served in the navy for five years, from the initial gun captain to the current deputy captain, but everyone knows that after coming back this time, the second prince is estimated to be promoted to the captain of the detachment without any problems, and if he makes meritorious service this time, he may even be promoted to the position of deputy commander of the fleet.

The emperor sent the two princes together to enter the expeditionary force, which shows that Yu Xiaotian attaches great importance to this expedition, and this time they have made sufficient preparations, thinking of everything they can think of, as for whether they can successfully conquer New Spain next, then it depends on the performance of Luo Xianbin and the eldest prince Yu Zhenhua.

Yu Zhenhua followed Meng Fei to participate in the battle of the Japanese in the past few years, at first no one knew his identity, he was just a company commander of an ordinary company, but in the two-year battle of the Japanese army, Yu Zhenhua made great achievements, and at the end of the war, he was promoted to the rank of major and became the deputy brigade commander.

After the fall of the Wa Kingdom, Yu Zhenhua was appointed as the deputy governor of Donghai Province, and stayed in Donghai Province for more than a year before returning to China, and then his identity was revealed.

To everyone's surprise, only then did he know that he was actually the eldest prince, and he actually personally led the troops to participate in such a big battle, and won extremely high military achievements in the war, and in two years, he was wounded three times, and one was almost killed.

The Chinese in China suddenly have more respect for Xiaotian, as the emperor, he is actually willing to send the prince to the most dangerous battlefield, personally lead the troops to fight, born and die, so who can say that he is not?

Yu Xiaotian's prestige, including Yu Zhenhua's prestige at this time, became famous in the Dazhong Dynasty, and its prestige was so high that it can be said that it had reached an unprecedented level.

But this time, when Yu Zhenhua learned that he was going to send an expeditionary force to attack North America, he still asked for orders to fight, and was nodded by Yu Xiaotian and agreed, and was appointed as the deputy commander-in-chief of the expeditionary force and the commander-in-chief of the landing operation.

For such an appointment, it can be said that everyone expects it, and no one has raised any objections at all, which also makes Yu Zhenhua finally stand at the forefront of this big China and North Korea with his own efforts.

Later generations commented on this expedition, saying that this expedition, Yu Zhenhua played a vital role, after the fleet arrived in New Spain, led the landing force, fought very beautifully, the Spanish army and the colonial army, in front of the large Chinese army led by him, as if devastated, quickly collapsed, and finally made the large Chinese army successfully victorious, forcing the Spaniards to finally choose to surrender, completely withdraw from New Spain.

In the following years, Yu Zhenhua returned to China, and the second prince Yu Zhenshan served as the newly established governor of North America.

In the ninth year of Chengtian, Yu Xiaotian's decree changed the name of Australia to Tai O Province, officially announcing to the world that Dazhong has sovereignty over Australia, and no one is allowed to covet Australian territory anymore.

The Spaniards were not willing to fail, and in the tenth year of Chengtian, in addition to mobilizing a large number of ships and troops to try to counterattack, they also abandoned the previous policy of hostility with the Dutch, persuaded the Dutch king, won the support of the Dutch, and even persuaded the British, who were in a hostile state with them, to join the ranks of the Great China and Korea.

The Spaniards, the Dutch, the British, and even the French united to form a large expeditionary fleet to North America in an attempt to recapture New Spain, and all of North America, with the Spaniards promising to share the interests of these countries if they regained control of North America.

So the European joint expeditionary fleet immediately sailed to North America, and on the sea and land there, at the same time with the local garrison of the large Chinese army naval and land forces engaged in a fierce war, known as the North American War.

When Emperor Chengtian learned the news, he immediately mobilized more naval and land armies and rushed to the North American battlefield to fight against the European coalition forces.

On the North American side, after nearly three years of fierce naval and land battles, the European Joint Expeditionary Fleet finally failed, and the landed land was almost annihilated by the entire army of the Great Chinese Army.

As for the other belligerent countries, they also suffered heavy losses and had to withdraw to Europe, and the naval forces of the whole of Europe, after this war, suffered huge losses, and for a long time, they could not recover.

Later, the Europeans refused to admit defeat easily, and continued to send a lot of privateer ships to attack the warships and merchant ships of the Great China and North Korea on the routes where the Great Chinese and North Korean fleets often operated, and the two sides launched a sea war that lasted for several years.

In the end, because of the great advantage of the high-speed clippers of the Dazhong Navy, they completely defeated the smuggling ships sent by European countries, sank and damaged a large number of enemy ships and sailors, forcing them to finally order the withdrawal of these smuggling ships to reduce the losses of their personnel and ships.

In the twelfth year of Chengtian, the expeditionary force of the Great Central and North American Expeditionary Force captured Peru controlled by the Spaniards, and then captured Santiago, which was later Chile.

In the fifteenth year of Chengtian, the Dazhong army entered India, placing India under the jurisdiction of Dazhong, and completely controlling all the commercial trade to Europe.

In the winter of the fifteenth year of Chengtian, under the strong military suppression of the Great Chinese Army, the Dutch East India Company announced its surrender to the Great Chinese Dynasty, handed over the island of Sumatra and the Strait of Malacca to the Great Chinese Dynasty, withdrew from Southeast Asia, and announced the end of the Dutch colonial rule in Southeast Asia.
