On the other hand, Su Yizhi had once said that except for the ancestor who founded the sect, there was no one amongst the generations of Sect Masters of the Golden Pill Sect that could handle this Cang Yuan remnant. Even if someone found it, it would only harm them.
Ling Chuxi had already collected the Cang Yuan sword spirit and sword soul, so she knew the danger of doing this. Even if she and the Cang Yuan sword spirit worked together, it would still be dangerous. If she brought Su Yizhi along, she honestly didn't know if he would make it back in one piece with his cultivation intact.
So, after much consideration, Ling Chuxi decided to keep it a secret.
