What was simple, brute-force power? The "Origin of Power" ability was exactly that. It caused the enhancements from "passive skills" to undergo a qualitative transformation. Regardless of the passive skill, based on its basic bonus, it could greatly increase Su Xiao's four primary attributes, soul strength, and technique potential limit.
For Su Xiao, who had stacked up a massive number of "passive abilities," this was a qualitative boost. Moreover, after stacking passives for so long, he had gradually discovered a problem.
If equipment was an external enhancement, then "passive skills" were internal enhancements. Ultimately, these were additional boosts, and they differed subtly from things like body attributes, which completely enhanced oneself.
If one possessed a normal number of "passive skills," that subtle difference would be impossible to notice. The problem was that Su Xiao had stacked far too many passive skills, causing that originally tiny difference to gradually become a burden.
"Exclusive Supreme Passive of Power" perfectly solved this problem. Its principle was to devour "passive skills," allowing Su Xiao's physique to completely absorb their effects. Put more directly, it transformed what had been acquired later into an innate physical trait.
Of course, some functional "passive skills" still had to be retained. For example, "Combat Prosthetic Limb, Lv.EX." If it were devoured and turned into a physical ability, it would cause his physical abilities to become disordered. Keeping it as a passive ability was the most appropriate choice.
Conversely, those that purely enhanced his overall physical traits could be devoured. For example:
Basic Passive, Lv.EX.
Skill Effect 1: Perception +187 points.
Skill Effect 2: Potential limit of physical perception +12.
Skill Effect 3: Efficiency of perception, meditation, comprehending nature, ability development, and so on increased by 600% (this was a 600% increase based on the total of all existing bonuses).
