Baizhi was worried about the incident that transpired in the mines. Although she had secured victory, it was still not enough.
If the Sect Master hadn't informed her at the last minute, she wouldn't have been able to capture so many traitors and intruders. The sect would have suffered great losses.
Baizhi had suspected that the mines would've been the target, but she hadn't paid enough attention. She was so focused on dealing with Azure Mountain that she had neglected the situation in the mines.
She had thought that the mines were inside the sect, so she would have enough time to make preparations. The mines were important for the sect. Spirit ores weren't the only things found in the mines of this sect.
However, the mines were dangerous. The miners were instructed to dig bit by bit before they were allowed to venture deeper to find other treasures.
