Alone, I Knock on Heaven's Gate

Also known as Breaking Tradition in Cultivation: I Prove the Dao Through Science! Don't let the cover put you off; the story is great! It tells the story of a female lead who transmigrates from the modern world to an ancient cultivation world, relying on her modern experience and knowledge to overcome every obstacle and ultimately become a god. She uses modern knowledge to improve and optimize pill recipes and formations.

I transmigrated into the cultivation world and was judged to have a useless spiritual root. Hah, luckily I come from the 21st century and know full well that "knowledge is power." While others meditate to absorb spiritual energy, I study "spiritual energy dynamics." While others draw talismans through mysticism, I set up "standardized production." When I ascended in one leap and shocked the immortal realm, those old fossils finally realized: I wasn't some useless spiritual root. I was a once-in-ten-thousand-years Chaos Spiritual Root! I'll use science to become a god!
