Lilith's secret and change of race
Lilith could feel the aura of a Seventh Order Higher Existence rapidly approaching her. However, she did not panic at all and kept pushing her speed just enough but not too much, thus saving as much Mana as possible.
In a normal battle, Lilith probably couldn't win against Michael without paying a great price. At the very least, she believed her chances of victory were below 50%.
At the end of the day, Michael who was known as the Archangel of Fire was the holder of a divine flame. The problem was that this divine flame was not just any divine flame but was a 100% damage-focused one that would become increasingly powerful as its user became more enraged.
Against Michael's flame, Lilith was certain that the power of her Firmament Fragment left behind by the Ice Goddess Skadi would be negated by at least 90% not to mention her normal ice-like skills.
However... This was only the case under "normal" circumstances.
