Heart demons are something that every cultivator fears profoundly.
Unlike external forces, heart demons stem from the deepest fears and unresolved knots in the cultivator's heart.
The deeper the knot, the stronger the heart demon, and the greater the impact on the cultivator.
In the early stages of the Heavenly Level, unless someone recklessly alters their cultivation technique or tries to forge a new path different from their predecessors, thereby changing their cultivation method at the risk of their life, heart demons generally do not appear.
Of course, some people are deeply obsessive, allowing heart demons to take root and sprout; the stronger the obsession, the stronger the heart demon—this is a truth.
Once invaded by heart demons, the lucky ones may just lose all their cultivation, becoming ordinary people, but managing to hang onto their life, and with better luck, they might even have the chance to re-cultivate.
