Qinghe looked at the knife in her hand and felt that the legend was somewhat unreliable. Immortals crafting weapons would likely be creating swords that drifted towards the heavens, not such portable small knives. Besides, this didn't seem forged from Ten Thousand Years Permafrost at all, claiming it was Mystical Iron seemed more credible. Furthermore, this knife was part of a pair, each with a strange power she could feel.
Therefore, in summary, Qinghe thought that what Jia Xiantian described as the Soul Devouring Knife was completely different from her own knife. And the reason the senior disciple had come looking for her might also involve some unknown secrets they weren't aware of.
Jia Xiantian, as if seeing through Qinghe's thoughts, chuckled softly.
