The imperial palace had the vanguard, rear, left, right, cavalry, and guerilla warfare armies. Apart from this, each of the four directions of the capital city had an army, the east, west, north, and south armies.
These troops were there to ensure the safety of the imperial palace and the capital city.
Meanwhile, the capital city outskirts had six great high ranking officers, each in control of their own army: the garrisoned rider, infantry, monster rider, eternal river, roaring fire, and reserve armies. These were the empire's central field army, the elites among elites.
Every single high ranking officer grasped a sixth of this army's power. They all had at least eight ranks of cultivation, so it was easy to imagine how high this position was.
Sharky was a little bit amazed.
