During the period when the Bronze Gate opened in the past, Zhanbao Zhenren remembered that from a remote part of the Mortal World in the Northern Continent, three Demon Cultivators from the Great Zhao Empire inadvertently entered the Bronze Gate area.
Their strength was not weak, yet their luck was poor, for upon entering the Bronze Gate, they faced the first sunrise over West Mountain.
The trio failed to escape the dark surge, and were disemboweled and devoured by the Fierce Ghosts and Demons within, later, for some unknown reason, these three Demon Cultivators were assimilated into Yin Demons sharing a single sinister mind.
They still retained the consciousness from their human period, yet their bodies could not be considered human by any measure.
Moreover, since they were originally merciless Demon Cultivators, once they became even more potent and malevolent Yin Demons, they naturally turned into beings that people dreaded upon hearing about them.
