Xu Daoxuan was the most inconspicuous gatekeeper in the Demon Suppression Bureau, sickly and barely alive. No one knew that an ancient sword spirit was sealed inside him. Every day, he endured sword qi gnawing at his bones, asking only to live in peace. Until one day, his gentle and refined fiancée, Su Wan, personally brought him a cup of poisoned wine. He smiled faintly and drank it, but the instant it went down his throat, he sensed a trace of stardust in the wine, something that did not belong to this world.
Su Wan was not human. Her true form was an infiltrator from an extraterrestrial civilization born of a meteor from beyond the heavens. Disguised as his human fiancée, she was trying to steal the core of the Nine Provinces Sword Embryo beneath the Demon Suppression Bureau. Forced to awaken the sword spirit to stay alive, Xu Daoxuan severed the nine heavens with a single stroke and embarked on a campaign against enemies from the stars.
He didn't want to save anyone. He just wanted to survive. Yet every time he swung his sword, he stirred up an even greater maelstrom: the old martial world, the hidden hands of interstellar powers lurking in the shadows, and the Heaven-Piercing Sword Prison hanging over every cultivator's head.
