This cultivation technique was created solely by Ancestor Daoist Taiqing of Mount Shu and has only ever been practiced by those from Mount Shu. Basically, anyone who practices it can be confirmed as a cultivator from Mount Shu.
"I am Lu Changsheng, the twenty-eighth Sect Leader of Mount Shu."
"I am Daoist Yuxuan, the tenth Elder of Mount Shu."
"I am Grandmaster Taixu, the twenty-first Sect Leader of Mount Shu."
Lu Changsheng and the others declared their identities.
"Very good, none of you have brought shame to our Mount Shu. Wait a minute, you are the twenty-eighth Sect Leader of Mount Shu?"
Grandmaster Tailin thought he had misheard.
The founder of Mount Shu in the Immortal Realm isn't the ninth or the tenth Sect Leader, but the twenty-eighth Sect Leader?
How could this twenty-eighth Sect Leader be stronger than the tenth Elder and the twenty-first Sect Leader?
"Senior, why have you appeared here?"
Lu Changsheng held considerable respect for his Mount Shu predecessor.
