Honestly, the ending of 'Legend of Fuyao' still sparks debates in my friend group. Fuyao finally ascends to the throne of the fairy realm, becoming its supreme ruler after overcoming all the political and mystical challenges. She's united the five elemental powers within herself, which was the whole point of her journey. The part that gets me is her relationship with Wuji. He gives up his own cultivation, his identity, everything, to be with her in the mortal world for a lifetime, because her position as ruler means they can't be together immortally. It's a bittersweet victory. She gets ultimate power but loses the epic love, at least in the eternal sense. They get one mortal lifetime together, which feels like a consolation prize after everything. I think the novel leans harder into the 'power has a cost' theme than the drama adaptation did.
Some readers hate that trade-off, calling it a downer, but it felt consistent with the story's stakes to me. Fuyao started as a lowly servant scraping by and ended up as the most powerful being, but alone on that throne. The final chapters have this quiet, almost melancholy tone as she assumes her duties, with Wuji's mortal life as a finite, precious chapter. It wraps up her arc from seeking vengeance and survival to accepting a burden of solitary leadership. The very last scene is just her, ruling, with that memory of their time together.
