"Heart demons have no form or substance, and can change in countless ways. They're close to being conceptual existences. And because they can magnify the weaknesses in a cultivator's heart... that's why they're so difficult to deal with. But what if a heart demon's form were manifested and fixed to some extent?" Senior White Two said.
Heart demons were difficult to deal with precisely because they could change in countless ways and had no form or substance. No matter how much martial power you possessed, you couldn't hit them.
During the Heart Demon Tribulation, heart demons could take countless forms. They could be a stone, a blade of grass, someone familiar, a stranger, an enemy, an animal, or a demonic beast. They could even be a patch of darkness, a full moon, or the rising sun.
As long as a cultivator had a weakness in his heart, the heart demon would transform into that weakness's shape. Writing, directing, and acting in a grand drama alongside the cultivator was also one of the heart demon's specialties.
A certain type of idiot possessed a special ability: they could drag their opponent's intelligence down to their own level, then defeat them with their abundant experience.
Heart demons possessed a similar ability. They would drag a cultivator into their own main battlefield, then use their abundant experience to kill him.
Conversely, what if an intangible, formless 'heart demon' were manifested to some extent?
There was no need to project the heart demon into the Present World. It only needed to be fixed into a single form instead of changing endlessly. As long as cultivators had firm wills, they would have a great chance of breaking through the heart demon. The success rate of surviving the Heart Demon Tribulation would rise by a large margin.
