This novel is also known as The Indomitable Master of Elixirs

She is the twenty-fourth century’s strongest immortal cultivator, but transferred into a world of magic where demons roamed rampant; a punching bag tyrannized and ostracized by her clan on one side while the scum of a man that is her fiancé humiliated, trampled her on the other side…

Want to ravage her? She laughs as she will soon teach them how to behave themselves!

Magic is amazing? Her Five Lightning’s Bombardment Talisman will turn you into ashes! Medication is very incredible? With one furnace of medicinal pills, useless can also become genius! A vigorous army of a million is very ferocious? With Scattering Beansprout Soldiers, all of you can slowly play!

Smilingly watching as those who court death act vilely without salvation. Those who submit to me prosper, those who oppose me, perish!
