The old ancestor of the Blade Demon Clan had extremely demanding innate requirements for cultivating the Demon Blade Domain.
Even the cultivation process itself was exceptionally difficult, leaving the Blade Demon Clan without any outstanding figures in the present day.
In fact, it was precisely these restrictions that kept the Blade Demon Clan from controlling more than a small territory in the entire Demon Realm, despite possessing such a powerful Demon Blade Domain.
