The Qing Clan's Immortal Executioner

In this world, there is an ancient bloodline known as the "Qing Clan." Their spiritual roots are not innate, but forged generation after generation through "torture." The clan's disciples must endure a family punishment called "Bone-Eroding Netherflame." Amid unbearable agony, it gives rise within their ruined bodies to the toughest, most violent, and most tormenting spiritual roots of all: the "Torture Immortal Spiritual Root." The stronger the spiritual root, the more intense the daily suffering from its backlash. The people of the Qing Clan are both prisoners of pain and monsters of power.
