In the south of the demon kingdom, atop the city walls, a large number of cultivators used the massive walls as a pillar, continuously casting spells towards the demonfolk ahead.

Whenever a demonfolk attempted to fly over the walls, these cultivators would rely on the wall's sturdiness to attack their underbellies from below, completely ignoring those attacking from beneath.

The walls were incredibly sturdy, rendering the demonfolk's attacks futile, allowing all cultivators to focus on dealing with those attempting to breach the barrier.

In this way, relying on the walls, they once again repelled the demonfolk's assault.
