Southern Han Dynasty (the separatist regime of the Five Dynasties and Ten Kingdoms, the southern part of Lingnan, the royal family is extravagant, the officials are corrupt, and the local forces are separatist) + low-level immortal cultivation system (spiritual energy depends on "resources", spiritual materials/spiritual veins/elixirs need to be "screened, calculated, and deployed" to maximize their effectiveness. Immortal cultivators are divided into four realms: "gathering Qi - channeling meridians - condensing essence - transforming gods". Ordinary monks are often trapped in "waste of resources" and difficult to advance.
