Man, trying to figure out the cultivation system from the Reverend Insanity wiki alone is a bit of a trap. The page lists all the terms—Primordial Apartment, aperture, Gu worms, the different paths like Strength and Wisdom—but it reads like a technical manual someone translated through three different languages. You get the raw components, but none of the feel for how it actually works in the story.
The real understanding comes from seeing it in action. Fang Yuan doesn't just 'cultivate' by meditating; he's constantly scheming, refining Gu, and exploiting loopholes in the system's own rules. The wiki can tell you that Rank Five is called a Gu Immortal, but it won't capture the sheer desperation and cunning required to actually get there. The system itself feels almost antagonistic, a brutal framework that rewards the most ruthless pragmatist. I've seen newer readers get bogged down in the wiki's taxonomy and miss that entire point—it's not a power fantasy checklist, it's a cutthroat economic and survival simulator with spiritual layers.
Honestly, I'd tell anyone curious to skim the wiki for basic terms, then just dive into the early chapters. You'll grasp the hunger and the mechanics together, which is how the author intended.
