In the Immortal Demon Transformation, the strength levels were usually divided into the following ten levels: [Level 1: Heavenly Demon] [Level 2: Earth Demon] Level 3: Human Demon [Level 4: Demon God] Level 5: Immortal Demon Level 6: Demon Emperor Level Seven: Heavenly Emperor Level 8: Demon Emperor Level 9: Emperor [Level 10: God Monarch] Among them, the Skyfiends, Earthly Fiends, Devilmen, Fiendgods, and Fiendcelestials were the five weaker levels, while the Celestial Thearchs, Demon Emperors, Monarchs, and Fiendgod Monarchs were the five strongest levels. Powerful characters usually had some special abilities or equipment that allowed them to easily cross the gap between their strength levels and challenge higher levels of strength.
