I Reincarnated as a Sentient Blade

One good deed, one cosmic joke—Yuan Yan helped an old lady cross the street and got transmigrated into a sword. Not a hero, not even a side character, but a literal weapon. No body, no face, just cold steel and an existential crisis. But if fate wants to forge him into a blade, he'll become the sharpest one in existence. From nameless weapon to legendary artifact, he'll slice through cultivation realms, shatter hypocrisy, and carve his own path to immortality—one swing at a time.
