One evening.
As Bai Yujun was packing up her stall, she saw two Demonic Cultivators enter the black market inn. There was no mistaking that demonic aura.
Her eyes rolled as she put away her wares and pretended to be merely passing by outside the inn. She watched the two Demonic Cultivators head up to the second floor, noted the location of their room, then circled around the inn and carefully sensed the area.
They were two Golden Core Stage Demonic Cultivators who had concealed their auras before coming to this black market frequented by Qi Refining Stage cultivators.
Bai Yujun wanted to know what they were discussing.
After searching around, her eyes lit up. She spotted a spider spinning its web, and one strand happened to be connected to the window of the room occupied by the two Demonic Cultivators. Though a spell blocked out sound, it could not stump a certain snake. She had found an even better way to eavesdrop.
Sound caused vibrations. In particular, since the spider silk was connected to the window of the two Demonic Cultivators' room, the sound would make many objects within the room tremble faintly. And because this strand was attached to the window, it could capture those traces of vibration.
She silently approached the web without using any spells, merely placing a finger against the strand.
After chasing the spider up a tree, she began eavesdropping...
The faint vibrations traveled along the spider silk to Bai Yujun's finger. Closing her eyes, she remained perfectly still, sensing the amplitude of the vibrations and converting them into words. Before she knew it, the conversation inside became clearly audible.
"The Helm Master said the demon snake may have escaped. Your branch altar must investigate thoroughly. Here is her portrait."
