After the first improvement and development of the Ming Dynasty, the early modern musket began to appear in the infantry corps, and the infantry once again had the ability to fight against the traditional cavalry in actual combat. This made the entire Ming Dynasty's war against Mongolia and other countries smooth sailing for a while.

However, the development of the times constrained the Emperor of the Apocalypse of the Ming Dynasty, and in his time, the Ming Dynasty did not have a systematic scientific development system, and many modern applications could not be realized at all - the most important thing was the disadvantage of communications, which made the Ming Dynasty's foreign expansion war encounter a bottleneck that was difficult to break free.

Occupy a place but cannot rule stably for a long time, although the territory is vast, but can only appoint some governors to elect some locals to maintain control over a certain area. With the death of the Emperor of the Apocalypse and the death of some veterans, the Ming Dynasty began to live in turmoil, until gradually distant countries broke away from the Ming Dynasty and established themselves on their own, and the Ming Dynasty still did not find a good way to deal with it.

It was not until later that many new inventions appeared all over the world, and the single military advantage of the Ming Dynasty could not be extended to distant places in the absence of logistics and transportation. The industrial revolution that was advanced by the Emperor of the Apocalypse allowed the Ming Dynasty to continue, but most of the world under the Emperor of the Apocalypse eventually disappeared into the long river of history like the Mongol Empire.

Today's Ming Dynasty is still a vast superpower: it controls part of Siberia as far north as the Mongolian steppe, and even controls most of today's Vietnam and Burma to the south - the rivers and mountains laid down by the ancestors have not been completely lost, which is the only thing to be thankful for in the heart of today's Ming Emperor.

Of course, the issue of territorial loss cannot be clearly described in a few words, after all, it also involves the "Emperor Han" idea of the Emperor of the Apocalypse. This idea has always influenced the foreign expansion policy of the Ming Dynasty, causing irreconcilable contradictions between the Han and the locals, as well as various economic, political, and cultural matters.

In short, the Ming Dynasty has recently weakened to an extreme, and even the Manchurian rebellion, which was close at hand, seemed powerless to suppress it -- who would have thought that in the past few decades, even these Jurchens would have to call the servile title of "master" when they saw Han Chinese.

Of course, then again, if it weren't for the fact that these Jurchens who were far away in Liaodong groveled and secretly survived, and even intermarried with the Han people in order to protect themselves, they would have perished by the time of the Emperor of the Apocalypse. Even if they rebelled today, most of them had Han Chinese names and had short Han hair...... Those people with money rat tails are nothing more than some ministers and royals of the Jin Kingdom.

To get back to the point, with the continuous development of muskets in various countries in the world, the combat effectiveness of human civilization has also moved from cold weapons to the era of hot weapons. A mechanically proficient German invented the machine gun, an automatic firing weapon, and casualties in the war increased dramatically. In order to reduce the casualties of soldiers in war, some people began to study new defense systems, walls and trenches, and new developments began in these studies, which eventually evolved into fortresses and trenches.

Trenches are a kind of dug facility that can cover your infantry very well, and it has achieved unexpectedly good performance in actual combat. If the tunnels are dug well, there is no need to even fear the onslaught of artillery and a large number of enemy troops...... The first person in history who felt that digging a pit could win was definitely a genius and deserved the reputation of a pit god. From the day his invention was born, the war had lost the slightest beauty, only mud and bloody killings.

This invention that changed the mode of warfare reversed the ancient city walls and led to today's turtle trench defense tactics. After decades of evolution and development, the trench turned into a perfect defensive system, capable of resisting heavy fire such as large-caliber shelling, and was simply a difficult cheap fortress.

With a strong fortress made of reinforced concrete, and a dense mass of large-caliber permanent fortress guns. The border has become a nightmare for military commanders of all countries, and any attempt to attack first will be completely overwhelmed by the thousands of casualties.

Even if the super cannon is used for bombardment, as long as the shells with a caliber of more than 300 mm do not directly hit the trench node, they still cannot effectively kill the infantry inside, which is definitely good news for the infantry, especially the infantry of the defending side.

Germany has a cannon caliber of 600 mm, France also has a super mortar caliber of 450 mm, and the Ming Dynasty is equipped with 5 "Yongle cannons" on its Jiliao defense line, and the caliber even reached an astonishing 810 mm. These weapons were produced with one purpose in mind - to destroy the enemy's defenses.

Countless amounts of money have been spent on the research and development of heavy artillery in order to tear down the enemy's defense line, but the military of various countries still finds that the enemy's means of dealing with heavy artillery are cheaper and more effective -- as long as you dig deeper and more scientifically, you can make the large-caliber heavy artillery produced by tens of millions of gold coins useless.

Against this background, how to tear apart the enemy's strong fortifications during the offensive has become a major historical issue for the militaries of all countries. We have researched countless kinds of strange things, but they have been proven to be the failure of these inventions in actual battles again and again.

Until the recent outbreak of the war between Germany and Britain and France, the British carried ironclad cars with small engines, and partially broke through the German defenses. This news was discovered by the military attache of the Ming Empire in Britain, and the military attache immediately transmitted the news back to the Imperial Jingshi.

The Ming Empire, which had no way to deal with the Liaoshen defense line of the Later Jin, immediately launched the research and development and research of this new weapon, but it achieved little success in the field of engines. After all, the Ming Empire lacked the R&D and technological accumulation of fuel engines, and the steam engine that relied on coal burning obviously could not meet the basic requirements of vehicle miniaturization.

So Wang Jue, who has been paying attention to the development of this weapon, found William through a relationship? Arsene Wenger -- this down-and-out German engineer. He wants to squeeze out everything that this engineer has mastered and raise the level of fuel engine research and development in the Ming Empire. With this kind of thing, he can have a way to break through the defense line of Houjin with a small amount of losses, recapture the northeast of the Ming Dynasty, and complete the unification of the country in the true sense of the word.
