Stranded in the wilderness, he is rescued by a group of villagers and soon discovers that he has transmigrated into the new Sect Leader of the long-forgotten One Flower Sect—a once-powerful immortal sect now reduced to nothing.With no cultivation talent, no resources, and only a mysterious technique called the Life and Death Technique, Bok Taejin soon realizes that the key to reviving his sect isn’t just through martial arts—it’s through farming.

By cultivating the land, nurturing rare plants, and trading with nearby towns, he slowly builds a foundation for the sect’s return.But as word spreads of a declining sect suddenly producing miraculous crops and powerful elixirs, forces from the martial world begin to take notice.
