I really enjoy reading novels to figure out the structure and rules of the power systems, but what I like even more is when there are multiple paths to power and how they interact/compete against each other. Examples are Martial World with body transformation/essence gathering/soul forging, Desolate Era with body refining/ki refining/heartforce, World of Cultivation with ling power/consciousness/mo physique, or even Warlock of the Magus World with Magi, Warlocks, Sacrificers, Beast Spirit Masters, Gods, etc. I also enjoy a novel with one system but multiple paths within the system, giving a lot of variety all the same. Examples like Coiling Dragon with the 7 Elemental Laws and 4 Edicts, Heavenly Jewel Change with all the Physical, Elemental, and even Saint attributes, or Reverend Insanity with all the different kinds of Gu Master paths (fire, ice, metal, wood, light, darkness, lightning, blood, sound, poison, time, wisdom, transformation, strength, enslavement, etc.). It really gives so much possibilities even with just one simple power system of Gu masters ranks 1-9. I also like how they handle multiple different attributes in both Spirit Realm with their Natal Palaces and also in Lord of all Realms with vortexes of attribute power. Anyway, any recommendations along these lines would be greatly appreciated. edit:Another novel that I just remember is Lord Xue Ying, which surprising introduced A LOT of new alternative cultivation systems in the recent arcs in addition to just the standards laws and profound truths system: hex, devour, ancient, voidwalker, cosmos emissary, Ancient Mother, bloodline, strongest warrior, etc. Really enjoying all the recent chapters and how it evolved from just the cliche xianxia power-up plotline.
