First, let's define the strength of the Fiend (or Demon).
One to Three-Star Fiend, Midgod, and Highgod Refine Divine Spark.
Four Star Fiend, who independently broke through to become Highgod, but did not fully fuse the two profound Profound Mysteries.
Five-Star Fiend are either divine beasts that have fully integrated two Profound Mysteries or have not Fusion Profound Mysteries.
Six-Star Fiend be formed by fully fusing three low-level Profound Mysteries; or by fusing two High-level Profound Mystery; or by fusing two low-level Profound Mysteries with divine beasts.
The Seven Star Fiend are divine beasts that have completely fused with four low- and medium-level Profound Mysteries; or completely fused with three High-level Profound Mystery; or completely fused with three low-level Profound Mysteries.
Prefect-level who has fully integrated five profound Profound Mysteries; a divine beast that has fully integrated four Profound Mysteries.
Furthermore, there are differences in strength among the Deity-level Refine Divine Spark. In the original work, during Linley's first Demon exam, the conflict he had with the Highgod who Refine Divine Spark was mentioned in that passage. It was said that Highgod Refine Divine Spark could potentially inherit the Profound Mysteries fused within the original Divine Spark. In the original work, after Linley found his family and friends, Bebe also teased Yale, saying that Deity-level Refine Divine Spark spark could also try to fuse with the Profound Mysteries.
The proportion of Deity-level in the Higher Planes: When Linley was taking the Demon exam, there were thirty high -Deity-level Highgod and nearly a thousand mid- Midgod who went with him. This is the proportion of Deity-level among Demon. The proportion of Deity-level in the entire Infernal Realm should be much larger than this.
The original novel, in a chapter titled "The Invincible Highgod," states, "Only one in billions of gods is a Highgod!" This ratio is far too unrealistic.
For now, in the Higher Planes, the Highgod: Midgod: Lowgod is 1:1000:.
