"Heart Demon?" Li Xuan's heart slightly shuddered; an unusual unrest seeped into his mind.
The 'Heart Demon' corresponds to the 'Heavenly-Demon' as described in Buddhism; it is just known by a different name.
Taoism believes that Heart Demons are beings from the 'Outer Void.' They cannot possess a physical form in this world, and exist only as conscious entities.
Heart Demons feed off people's desires, drawing their strength from pilfering or corrupting the Tao Fruit and cultivation of practitioners.
Buddhism shares a similar view on Heart Demons, asserting that besides the human world, there exist six desire heavens including 'Four Heavenly Kings Heaven, Tavatimsa Heaven, Night Mo Heaven, Tusita Heaven, Huale Heaven, and Heavenly-Demon Heaven'.
Among these, the 'Heavenly-Demon Heaven' is the first of the six desire heavens, ruled by the Sixth Demon King, 'Boxun'.
