Da Ming started to ascend the throne

Chapter 1001
Although there are still sporadic battles in the Americas, with the end of the main war in Europe, the world has temporarily experienced a rare calm. It can also be said that because of years of war, most countries have been unable to fight.

However, the situation in Daming is different from most countries in the world. Not only is Daming not short of money, but it is also not short of population. Not only does it have a large number of overseas citizens, but the local population has also skyrocketed because it has solved the food problem.

By the end of the 21st year of Chongzhen, the population of Daming had reached 17 million. You must know that in the 5000th year of Chongzhen, the population of Daming was less than [-] million.

For Emperor Zhu Youjian of the Ming Dynasty, the more population the better, the American land still needs too many Ming immigrants to develop in the past, it is impossible to use all foreigners there, otherwise there will be problems after a long time.

However, with the skyrocketing population of Ming Dynasty, this problem in the Americas will be completely resolved within 20 years, and the proportion of the population there will be controlled at about three floors.

At the beginning, Zhu Youjian didn't intend to have children in this time and space, but as he gradually adapted to the Ming Dynasty, and with the rapid expansion of the Ming Dynasty's territory, Zhu Youjian also let himself go. nature.

As a result, the beauties in the harem were shot one after another, and 32 of the 25 concubines were pregnant with dragon species. The emperor's marksmanship almost reached the level of a spear master.

In November of the 21st year of Chongzhen, Empress Qin Mingyue successfully gave birth to his first biological son Zhu Ciqian in the Ming Dynasty, the imperial concubine gave birth to the prince Zhu Cikun, and the imperial concubine gave birth to the princess Zhu Weiyu.

The 21st year of Chongzhen was a very good year for Zhu Youjian and the entire Ming Dynasty.

Not only did the Ming Dynasty develop well in all aspects, but it also won countless foreign wars, adding more than 1000 million square kilometers of territory, not including the Americas and Australia.

The Royal Academy of Sciences of the Ming Dynasty developed a pedal sewing machine, and it has been put into mass production. The era of Huaxia sewing clothes with the first effort is over.

Because this is not very urgent, Zhu Youjian did not provide them with technical drawings, and it was completely worked out by the new generation of scientists themselves.

The development of internal combustion engines has also begun, but due to industrial development issues, there is still a long way to go.

However, light machine guns and sniper guns have been successfully developed. The light machine gun that Zhu Youjian wanted last time was developed into a heavy machine gun by them.

High explosives have also been developed, and there are already experimental samples of landmines and mines.

The development of landmines and sea mines now is not the relatively primitive landmines and sea mines in the early days, but high explosives have been used.

The earliest sea mine in the world is the "underwater mine" manufactured by the Chinese in 1549 AD.

This kind of mine uses a wooden box to make the shell, and the seams are waterproofed with putty. The rope under the wooden box is connected to the iron anchor to control the depth, and the controller manually detonates it. This is the earliest recorded mine.

In the 18th year of Wanli, Tang Shunzhi, a military strategist and anti-Japanese hero of the Ming Dynasty, wrote a book "Wu Bian", which described in detail a method of making and arranging "underwater mines":
"Use a wooden box as the thunder shell, paste the joints with putty for waterproofing, and put black powder in the wooden box. His firing device is controlled by a long rope, and the rope under the wooden box is connected to the iron anchor to control the mine body. depth in the water."

During the Ming Dynasty, Japanese pirates invaded the southeast coast of my country more frequently.

In order to fight against the invasion of Japanese pirates more effectively, the coastal civilians of the Ming Dynasty used mines to attack Japanese pirate ships and achieved good results.

In the 19th year of Wanli, inventors of the Ming Dynasty invented the world's earliest drifting mine based on the principle of water mines—the "underwater Dragon King Cannon" with burning incense as the "timer" and "fuze line".

In the 28th year of Wanli, Wang Minghe, a general of the Ming Dynasty, invented the "underwater thunder" with ropes as the touch line based on experience.

In the 29th year of Wanli, it was improved into a touch-line floating mine, which is the earliest triggered floating mine in the world.

Afterwards, the wise Chinese invented floating mines made of cow bladders one after another.

In the 30th year of Wanli, this kind of floating mine was successively improved into the triggering floating mine of the touch line fuze, and it played a role in naval battles many times, blowing up enemy ships.

The Chinese are the inventors and earliest users of sea mines, more than two centuries earlier than European and American countries.

In the Russo-Turkish War in the 18th century, the West used mines for the first time in warfare, and later became famous in the American Revolutionary War.

In 1776, American inventor David Bushnell designed the first real sea mine in the West, named it "torpedo".

The principle of this weapon is similar to the structure of the "underwater mine" invented by China 200 years ago. The only difference is that the wooden box has become a beer barrel.

In August of the same year, this "torpedo" was put into actual combat, and it sank the British "Cibras" in the first battle.

Two years later, Washington, the leader of the American Revolutionary War, used "torpedoes" to attack British warships docked at the mouth of the Delaware River in Philadelphia.

It was this unintentional move called the "Keg War" by later generations that brought unexpected revolutions to subsequent naval battles.

In the first industrial revolution, with the emergence of various new technologies and weapons such as high explosives and detonators, various standard sea mines were born one after another, but they never broke through the limitation of triggering sea mines.

The mass production brought about by the industrial revolution paved the way for the large-scale use of naval mines.

In World War I, the warring parties laid a total of 31 mines, sank 148 ships, 54 submarines, and 586 merchant ships, with a total tonnage of about 122 million tons.

During World War II, in order to fight against advanced ships, Germany took the lead in developing non-triggering mines such as magnetic mines, acoustic mines, and hydraulic mines.

Compared with triggering mines, these "underwater ambushes" equipped with precision fuzes can carry out precise strikes on specific targets according to the sound field, magnetic field, water pressure and other characteristics of different ships.

This war reached the peak of the use of sea mines by human beings. More than 80 mines were dropped unprecedentedly, and more than 3700 ships of various types were sunk.

After the war, all countries fully realized the super high "cost performance" of sea mines, and stepped up the research and development of new sea mines.

More representative examples include the Swiss "Storm" mine, the British multi-sensor "Stonefish" mine, the Soviet Union's directional attack mine, and the self-propelled mine developed by the United States.

However, due to the characteristics of water mines that are easy to cloth and difficult to sweep, and have a long underwater life cycle, during this period, new and old members competed on the same stage.

Especially for some countries with underdeveloped naval and air equipment systems, old-fashioned mines still brought them unexpected results in local wars after World War II.

During the Vietnam War, the USS Card was sunk by a mine.

During the Iran-Iraq War, an old-fashioned mine worth only US$1500 blew a big hole in the USS Roberts, a new type of missile frigate, causing nearly US$1 million in damage.

For this reason, sea mines, like chemical weapons, are known as "atom bombs for poor countries".

Landmines also first appeared in the Song Dynasty of our country, and Qi Jiguang, a famous general in the Ming Dynasty, used landmines many times during the anti-Japanese war.

However, sea mines and landmines were relatively simple at that time, and the sea mines and landmines developed by the Royal Academy of Sciences of the Ming Dynasty are close to the early level of later generations.
