Unlike other ordinary Skills, [Soul Enemy] was a product of humanity's most advanced alchemical technology. It possessed the unique feature of automatically evolving as a Professional grew.
When Fang Zhou transitioned from the Apprentice Stage to officially become a Black Iron Undead Mage, [Soul Enemy] had also automatically upgraded to a Black Iron-level Skill.
Unfortunately, Fang Zhou had spent his Apprentice Stage cultivating safely at the Sea City Military Academy, never engaging in combat with Abyssal Demons. Although he had a few live combat experiences, those had all occurred in academy-controlled environments against captured Demons.
Under such circumstances, the quantity and quality of these battles were insufficient to elevate the [Soul Enemy] Skill from Perfection proficiency to Instinct proficiency. As a result, after advancing to a Black Iron-level Skill, its proficiency dropped from Perfection to Skilled.
