Expelled from the Sect? Am I Not an Ancestor?

Yang Xuan had been in seclusion for tens of thousands of years. When he woke up again, he found himself in the Lower Sect Law Enforcement Hall. "Elder! This is the man who behaved obscenely towards his disciples in the Sutra Pavilion. I hope the elder will tell you clearly!" Before he could figure out the situation, he was accused by a female disciple. Just when Yang Xuan was about to defend himself, the elder made a verdict. The falsely accused female disciple was escorted to the inner sect, and the suspect Yang Xuan was expelled from the sect! ······What happened to the world of cultivating immortals? Did I remember that I am not the ancestor?
