I Reincarnated as a Cultivation Manual and Conquered the Heavens!

Gu Yuan's afterlife takes an absurd turn when he wakes up as a dusty Qi Refining manual on a forgotten library shelf. Not a legendary sword. Not a divine artifact. A basic cultivation textbook. But this book has ambitions far beyond teaching beginners breathing techniques—it's destined to journey across infinite realms, collect disciples, and rewrite the laws of cultivation itself. One page at a time, Gu Yuan will prove that even the humblest grimoire can become a legend.
