The Duanmu Family has some knowledge of most of the cultivation techniques of the Taixu Sect.
The Illusion Shatter Hand is a basic technique, not considered obscure, and many people learn it, but few ever enhance it to become the Silvershade Weaver.
Duanmu GuZhu knows the difficulty of practicing the Silvershade Weaver and understands the sect's secretive attitude towards this technique. It seems that no one pays attention to this technique, but in fact, someone is always secretly watching. Now that Liu Xingyu has successfully cultivated the Silvershade Weaver, he can easily enter the upper court's line of sight.
If he can quickly advance to the Nascent Soul Middle Phase, entry into the upper court is almost certain.
