The creature named Lu Shu was an ancient extraordinary beast that likely existed during the third Yuanhui era. According to the records in the Mountain Sea Chronicles, Lu Shu could sprint across the land faster than lightning without wings, yet capable of Riding Clouds and Mist. Its claws could easily tear through tigers and leopards, and many cultivators would tame such extraordinary beasts to serve as their mounts.
However, after the Age of Deity, Lu Shu essentially vanished from the world.
"Lu Shu? The name is so strange. How did you come to know the name of this animal, brother-in-law?"
