The Great Wall, a defensive means of agricultural civilizations against nomadic civilizations.
In most dynasties of Hua Country, the Great Wall played a crucial role.
Strong dynasties, like those during the Han and Tang dynasties, used the Great Wall as a base for attacking foreign races.
Weaker dynasties, on the other hand, used the Great Wall for defense.
Falling dynasties could regard the Great Wall merely as a scenic view.
Beyond the Central Plains lay the world's most expansive grasslands.
Numerous grassland cavalry howled through the heavens and earth, becoming the most chilling cavalry of that era.
Xiongnu, Xianbei, Rouran, Shiwei, Turks, Khitan, Jurchen, Mongols... each was a formidable existence in their time.
And the Great Wall stood on that impossibly long boundary line, which drove many to despair.
It could signal beacon warnings, provide high barriers for defense, and serve as a base for troop deployment.
