Lin Mu had been suspecting that Dugu Shanhe used some questionable technique and his actions had confirmed it. But learning more from High Elder Juxue made Lin Mu realized just how questionable it was.
"Have there been other people using it before? In the recent times?" Lin Mu questioned after thinking something.
"There have been a few, yes. But none in the Rust Sky world." High Elder Juxue answered. "Due to the obvious effects of the technique, most that do encounter a practitioner end up forgetting about it. The technique's ability to affect memories is very problematic." He added.
"Yes. Dugu Shanhe did say that he has been 'collecting' them for a while." Lin Mu replied. "He also seemed rather… Fixated on them."
"That is a common side effect of the Six Faiths Soul Mystic Art. It makes its practitioners addicted to harvesting memories from others. That was its intended purpose, after all." High Elder Juxue answered.
