This true history refers to the last period of history before the fall of the Tokugawa shogunate in Japan. The so-called "heaven and man descended from the sky" refers to westerners who had powerful ships and guns at that time. The event of heaven and man falling from the sky is the "black ship incident" in Japanese history. The content of the "Black Ship Incident" is that American Brigadier General Perry knocked on Japan's closed trade door with a modern warship.
This incident prompted Japanese scholars and rulers to frequently contact the culture and technology of the western world, which led to the collapse of the Tokugawa shogunate and the establishment of the Meiji government. The Meiji government later carried out a comprehensive westernization, which finally made Japan enter the ranks of imperialism and had the right to speak when the interests of the western world were divided.
abstract
At the end of Edo, aliens called "Heaven and Man" attacked. The war between heaven and earth broke out instantly, and a large number of samurai and anti-foreigners took part in the battle with heaven and man.
After seeing the great strength of heaven and man, the shogunate signed an unequal treaty with heaven and man without authorization, allowing heaven and man to enter the country. Later, a "Knife Scrapping Order" was issued, and all the samurai's knives were taken away. Since then, heaven and man have been rampant, and the shogunate has become a "puppet regime." In this era, a samurai and his companions lived a whimsical life happily.
