Drowned by bills, rain, and regret, Xiao Ranyu died saving a stranger. He expected nothing in return.
He woke in another world.
Not just any world—Battle Through the Heavens. Reborn into the Xiao Clan as the younger brother of Xiao Yan, the future Flame Emperor himself.
But fate never gives without cost.
A system stirs within him, its voice cold and exacting:
> [Sign-In Protocol activated. Soul synchronization complete.]
Power lies within reach—but so do danger, secrecy, and the burden of choice.
With fragments of a forgotten legend burning in his blood and a mysterious flame coiled in his soul, Ranyu must carve a path between shadow and fire.
He isn’t here to play support.
He isn’t here to kneel to destiny.
This time, he’ll forge his own legend—or be consumed by the flames trying.
Alright, let’s get one thing straight—I didn’t plan to write this fanfiction. I was just your average cultivator of webnovels, peacefully reading BTTH for the hundredth time, until my brain went: “What if someone had a flame physique so absurd it made Yao Lao cough up blood?” And boom—Xiao Ranyu was born. This story isn’t your typical MC-gets-flames-and-one-shots-everything tale. Well… okay, it is a little, but I promise there’s more than just explosions and arrogant young masters being reduced to charcoal. There’s a system, some spicy romance, ridiculous cultivation breakthroughs, and the occasional moment where even I don’t know how things got so chaotic. I’m mixing canon events with original arcs, messing with power scaling just enough to keep it fun, and adding a protagonist who’s basically a walking inferno with a smug grin. If you're a fan of: Fire-type MCs with enough confidence to burn the heavens, Familiar BTTH characters (but with fun twists), And chaotic system-assisted progress… Then give this story a try. If you don’t like it, I blame the system. If you do like it… welcome to the flames.
