The identity of a Nanwu Sword Sect sword cultivator serves as a good cover.
For over half a year, Song Yan's "Granny Fox" shadow puppet, in this guise, has entered no less than three secret realms. She made the acquaintance of many loose cultivators but was unable to find blood suitable for Song Yan.
However, it wasn't entirely fruitless. At least, through everyday interactions, Song Yan heard some things about the "Ancient Teleportation Array."
...
Cultivators told him that, a long, long time ago, the North and South of this continent were connected. The so-called "Wu, Shu, Wei" Three Kingdoms were merely a small nation that split from the continent's southern part. In the past, there seemed to be teleportation arrays that could directly connect the North and South, but now it's all shrouded in the mists of time.
This piece of information roughly provided Song Yan a possible direction for the "Ancient Teleportation Array" — the North.
