The distance between Clear Jade Mountain and the Mysterious Valley was not far to begin with. The two of them rode fast day and night, covering the distance in less than four days.
Before their arrival, they changed their attire.
They disguised themselves as members of the so-called Purple Sword Sect, using the handwritten invitation from Taoist Cangming.
In the vast Western Ridge region with dense mountains and rivers, even the locals couldn't be sure if the Purple Sword Sect truly existed.
If the people of the Nether Spring Sect in the Mysterious Valley wanted to investigate, by the time they made inquiries, the matter on this side would have long concluded.
Therefore, they were not worried that they would be discovered.
