The attitude toward immortal transformation differed, marking the distinction between the Daoist and demonic factions, and those of the eclectic practitioners.
The true Xuanmen Orthodox, emphasized using profound mana to suppress immortalization. Even if one refined their Primordial Spirit or Dharma Body, as long as they kept it concealed and did not reveal their true form, they could pass for ordinary people.
The Demon Sect, by contrast, sought to harness immortalization. In battle, they would transform into Demon Gods, possessing astonishing combat power, but also becoming extremely prone to descending into madness, turning into lunatics.
