A incomplete ancient book written by Lu Li's family, "Earthly Evil Yin Chapter", records that the ultimate ability of the Soul Burial Master lineage is not to "raise evil spirits into spirits", but to "point evil spirits into veins" - to transform evil places or powerful resentful spirits into "Yin Vein Spiritual Pivot" that nourishes one party and brings blessings to future generations. But this method has long been lost, and legend has it that it requires paying an unimaginable price. Lu Li's grandfather died because he tried this method forcefully, and the family also withered because of it.
