Chapter 74: Great Wall

Great Wall.

It was the utmost priority for any ancient regime.

The Central Plains, as an agrarian civilization, had the ferocious nomadic tribes of the grasslands as their greatest enemy.

Before the Great Wall was built, barbarian cavalry would frequently invade the south to plunder every year.

Moreover, since these were small-scale cavalry, highly mobile, they would simply raid and kill, then leave, leaving no options for defense.

It was not until the appearance of the Great Wall that the stomping of horse hooves was halted.

Now, if the nomadic tribes wanted to raid, they had to pay a tremendous cost.

They either had to attack cities or traverse mountains and ridges on foot.

The former required a heap of human lives, while the latter, even if successful in plunder, meant being chased down to death without the aid of warhorses.
