The Black Winged Dragon Roc remained silent for a long time, its massive, grim eyes showing a mix of complexity and reminiscence, as if recalling events from tens of thousands of years ago.
Just as Fang Lin had suspected, this Black Winged Dragon Roc had indeed once followed the Demon Saint Jin Zhulong in the past, serving as one of his most capable demon clan generals.
However, Jin Zhulong eventually disappeared, and the demon beast clan suffered heavily from an ancient calamity, with countless casualties. The surviving demon beasts, disheartened, all went into hiding.
The Black Winged Dragon Roc also retreated into these ten thousand mountains during that time, remaining dormant here for tens of thousands of years, never leaving the area.
As generations of Demon Saints came and went, the Black Winged Dragon Roc did not respond to any of them, unless a Demon Saint personally came to invite it. Without such invitation, it would not leave this place.
