In the cyber city "Longyuan" on Titan, veterinarian Lu Shen just wants to run his mechanical pet clinic safely. Until he picked up a mysterious "mechanical Kun egg". Kun, who grew up by devouring data, the strange reflection that overlapped with him in the mirror, and the restorer Su Yan who always appeared late at night with ancient magic weapons - all clues point to the truth of Longyuan Colony: this neon city was built on the ancient Dragon Palace Prison that suppressed the outer gods of the universe. As the last descendant of the dragon clan, Lu Shen was forced to control the ever-evolving Kun and deal with the torrent of data and the pollution of heaven. And his choice will determine whether this cage is a refuge for civilization or a sacrifice ground for all souls.
