So some people changed their strategy, starting to take the high-level route, specializing in pretending to be mysterious and deceiving the rich and influential, which could make the impact of the performance greater and spread the fame further...

But doing this was very dangerous, and if not done well, it could cost you your head. There are many records of predecessors who failed and were caught. The general public's understanding of sorcerers mostly comes from the Xingshen Sect sorcerers.
Many anecdotal notes about sorcerers and their techniques are also related to the Xingshen Sect.
