Normally, if an unfamiliar Cultivator isn't wearing their Sect's standard robes, it's difficult for anyone to discern their Cultivation Technique, let alone their background, just from their aura before they've even acted.
Unless they have specifically cultivated a special Secret Technique.
But there are three Sects whose members have such obvious characteristics that anyone with a bit of experience can identify their Cultivation Technique from their temperament and aura alone.
This is because the people from these three Sects are all known as "madmen," and they naturally carry an air of insanity.
There are the Sword Madmen from the Lingxiao Sword Pavilion, who dedicate their entire lives to the Sword Dao, possessing nothing but their swords.
