I've always been curious about that myself. Scattered interviews and forum posts from the author, Gu Zhen Ren, paint a picture of dissatisfaction with common tropes. It feels like he set out to deliberately invert every typical xianxia protagonist trope. Instead of a righteous hero gaining power through luck and benevolence, we get Fang Yuan, a being whose only creed is his own benefit. I think the core inspiration was a simple, brutal question: what if a character pursued immortality with the cold, uncompromising logic we associate with a machine or a force of nature, stripping away all pretenses of morality or loyalty?
Some fans point to older, darker wuxia novels as an influence, but the sheer consistency of Fang Yuan's amorality feels like a new beast. It’s less about being inspired by another story and more about being inspired by an idea—the idea of exploring the absolute extreme of a self-interested pursuit. The world-building, with its intricate Gu system, feels like a natural extension of that; a cruel, resource-based economy that perfectly facilitates such a character. Reading it, you sense the author’s intellectual delight in constructing this bleak, internally consistent puzzle box where traditional heroism is not just futile, but stupid.
