Cultivation by Calculation

She prayed for help with Advanced Math. Instead, the heavens gave her an entirely different problem to solve: immortality! Tan Qingwen was an ordinary university student whose greatest enemy was Advanced Math. But when a desperate prayer to the Exam God sends her hurtling into another world, she awakens in the body of a disgraced cultivator with a troubled past and an uncertain future. Her new reality? A shabby hut, a struggling spiritual rice field, dangerous sect missions, and barely enough resources to survive. Worse still, the body's previous owner died under mysterious circumstances involving a sinister demon soul. Fortunately, Qingwen has one advantage no one could have predicted: modern mathematics might just be the ultimate cultivation cheat! Armed with a mysterious golden book and her knowledge of mathematics and science, Qingwen begins approaching cultivation problems in ways no one has ever considered. Why struggle to circulate spiritual energy when you can map its pathways using three-dimensional coordinates? Why rely on expensive cultivation pills when a little agricultural science might produce something even better? And who knew calculus could help summon rain? With an adorable orange cat for company, a modest spiritual farm to tend, and countless experiments waiting to be conducted, Qingwen is determined to carve out her own path toward immortality. But the cultivation world isn't all peaceful farming and magical discoveries. Behind the beautiful immortal mountains lurk ruthless sect rivalries, jealous geniuses, dangerous secrets, and enemies who would gladly destroy her for the knowledge she possesses. As her unconventional methods attract increasingly powerful attention, Qingwen must learn that not every problem can be solved with a formula, and not every enemy plays by the rules. Can an ordinary girl armed with mathematics, determination, and a little ingenuity calculate her way to immortality? Or will the ruthless world of cultivation prove that some equations simply have no solution? A female-lead xianxia cultivation novel blending cozy slice-of-life adventures, magical mathematics, spiritual farming, an adorable feline companion, clever progression, humor, and thrilling sect intrigue.
