As for the "Heart Fire," it all possesses the essence of "Dao."
The Black Chi thus pointed out the ultimate paths of fire in the world—Object Fire, Energy Fire, Mysterious Fire, Heart Fire. Mastering these four kinds of magical flames that contained Dao essences meant having control over all fires in the world, hence ascending to the Dao stage and grasping the [Dao Fire].
The [Chi Fire] is precisely the legendary "Dao Communicating Mysterious Fire."
And if we set aside the pursuit of these loftier paths for the moment, as an Immortal Fire Seed obtained from the Immortal Hunting Destiny, the development and use of the [Chi Fire] itself is already a profound discipline.
According to the Black Cat, the characteristics of the [Chi Fire] are threefold.
Firstly, Chi Fire is the best kind of spiritual fire in the world.
Secondly, Chi Fire is visible, but it has no temperature of its own and cannot be perceived by any sense other than sight.
