A group of people left the city wall behind, entering a flat area of about ten miles in breadth.
Having crossed this ten-mile stretch, they would formally arrive at the Black Sea.
Of course, this area was garrisoned with a large number of soldiers, aggressive Subspirit Artifacts, and the like.
As well as numerous puppets.
Various strategies for troop formation and enemy engagement were in place.
The 16 fortresses, established here for many years, had developed very comprehensive defensive measures against enemies.
In this ten-mile area, soldiers numbered in the hundreds of thousands, enough to deal with most demon beast attacks.
And also the frequent stealthy demon beast raids.
The abyss demon beasts would launch a large-scale assault every hundred years.
But on regular days, there were also various small-scale attacks.
If they ever encountered an onslaught of demon beasts that was too difficult to repel, these soldiers could immediately retreat behind the city walls.
