Warriors who reach the Fierce Realm would develop their own unique martial arts style. Due to differences in Soul Casting techniques and martial skills, each person's style varies.
Even disciples taught the same heritage by a master could end up with vastly different combat styles.
The fundamental martial skills of the Evil King Palace traditionally involved using the genuine restoration method for soul casting, but Duan Longcheng took a different path, forcefully merging a Yellow Dragon Remnant Soul with the Mimicry Technique to forge this Red-eyed Evil Dragon soul.
The most significant characteristic of a soul crafted by the Mimicry Technique is its ability to fight in sync with its master, because the spirits mimicked by this method often go through the process of "spirit pinpointing."
Put simply, "spirit pinpointing" involves giving subconscious commands to the soul.
