In the grand hall spanning a thousand miles, rows of ten-meter-square, pitch-black spirit gold cages were neatly arranged, stretching endlessly into the distance.

These cages were specially crafted artifacts designed to isolate spiritual energy, restrict magical powers and divine abilities, and suppress physical strength and innate bloodlines. They were specifically used to imprison high-level cultivator slaves.

Qing Muling and his entourage, accompanied by several managing elders, walked along the spacious corridor, inspecting the condition of the cultivator slaves within the cages.

Each cage held varying numbers of cultivators, both human and non-human, with cultivation levels ranging from the Feather Transformation Realm and Ascending to Immortality Realm to the Elemental Immortal and True Immortal realms. Occasionally, there were even a few Xuan Immortal realm cultivators.
