The Thunder Demon Kingdom is a major demon country on the mainland of the Divine Land, intentionally preserved by the various major sects on the main island, specifically used for training the next generation of newcomers.
Normally, the lord of a large demon country should be above level 300, but this is the human main island, so it's impossible to retain such a powerful demon clan in the heartland. Since the first demon lord was slaughtered, subsequent demon lords have not exceeded level 300.
The demon country has three important passes. The one located in the south is called Thunder Eagle Fortress, guarded by the Thunder Eagle King, one of the ten great demon commanders of the demon country. The most common demon army at this pass is the Thunder Eagle Demon Army.
They are entirely composed of eagle demons over level 100, with their total number reaching tens of millions, possessing very strong combat power.
