The Kun-Demon was originally known as the "Thousand-Mechanism Mechanical Apparatus." During the era of the Dao Court, they were flesh-and-blood puppet automatons created by the immortals and gods to reshape the world—a form of artificial Demon Spirit.
Their prototypes were various mindless insects, but the final result was a mechanical automaton capable of shrinking to the size of an ant or expanding to immense proportions. They could work in coordinated swarms to build massive structures or perform maintenance on small facilities. They were infinitely versatile, capable of modular assembly at will, and were the favored tools of the Earth-and-Wood Immortals. The Ancient Immortal Ruins—specifically the "Northern Heaven Taixu Shipyard Grotto-heaven"—were filled with floating islands and steel structures taller than mountains, almost all of which were autonomously constructed by the Thousand-Mechanism Mechanical Apparatus according to blueprints; the relevant immortals only needed to inspect them periodically, never having to lift a finger themselves.
However, during the Tianyuan Heart-Demon Great Catastrophe, the Thousand-Mechanism Mechanical Apparatus, which had once permeated every corner of the Dao Court, all rebelled.
