Okay, so the 'Rantai Bumi' story you're asking about is most likely a fan translation or regional title, which can get super confusing. Based on my digging through forums and translator notes, I'm pretty sure we're talking about the Chinese xianxia web novel 'Chain of the Earth' (or sometimes 'Earth Chain'), originally by an author like Wo Chi Xi Hong Shi maybe? The naming conventions from Chinese to Indonesian/Malay are a total minefield.
Anyway, the core cast. It revolves around this young guy, Lin Fan (or maybe Lin Feng—translations vary), who starts off as a complete underdog in a brutal cultivation world. He's not the chosen one; he's more like the guy who gets repeatedly punched in the face by fate but keeps getting back up through sheer, stubborn cunning. His initial 'cheat' isn't some overpowered inheritance but a weird, seemingly useless artifact linked to earth-elemental energies that everyone else overlooks.
Then there's Su Yao, the female lead from a prestigious clan who initially looks down on him. Their dynamic is less insta-love and more a grudging alliance that frays at the edges constantly. She's fiercely pragmatic, and her loyalty is always conditional on his survival utility, which makes their eventual trust feel earned, not fated. The main antagonist isn't a single person for a long time; it's more like a series of arrogant young masters from bigger sects, like the insufferable Zhao Jun, who represent the systemic oppression of the world Lin Fan wants to smash. The mentor figure, Old Man Dust or something similar, is a classic trope—a fading remnant of a lost era who provides cryptic guidance that mostly just gets Lin Fan into deeper trouble. The characters are archetypal but executed with a specific focus on the psychological grind of climbing a power ladder where every rung is greased with betrayal.
