The Immolation Spell of the Three Elements

The Mystic Cyan Sect had a method called the Immolation Spell of the Three Elements. It allowed its user to enhance his powers for a short duration albeit with a terrible cost after its use: the spell would consume and damage its user's heart and meridians. Hence, all disciples of the Mystic Cyan Sect were prohibited from practicing this spell. But it was by chance long ago, that Xiao Chen had once managed a glimpse on this forbidden skill.
