After I Transmigrated into a Book, the Male Lead Became a Sickly, Scheming Black Lotus

A goofy little cultivation fairy x a paranoid, scheming green-tea type

A goofy female teacher worked late every night on lesson plans, countless forms, polishing her lessons, grading assignments... until she died from overwork and transmigrated into the world of the epic masterpiece Under Heaven's Rule, where she began her career as a force for justice.

The heroine cultivates immortality, so even at her weakest, she is far from helpless. Besides, she always carries medicine and values her life dearly.
