Song Ciwan received her Foundation Establishment quest: to her surprise, she had to enter the Demon Realm and gather thirty stalks of five-hundred-year-old Luming Grass!
The point of this quest wasn't the Luming Grass, but entering the Demon Realm.
Song Ciwan recalled that before entering this Secret Realm, there were three Gates of Light, each inscribed with a seal script character: Human, Fiend, and Demon!
'Where is the Demon Realm? How do I get there? And how do I get back?'
Song Ciwan also noticed another key piece of information the White Dragon Head had just mentioned: the Mortal World Female Cultivator, Song Qiu.
She immediately asked, "Excuse me, two emissaries, what is the meaning of 'Mortal World'? And how am I to enter the Demon Realm?"
