I Conquered the Obsessive Prince with Academic Brilliance After Transmigrating

When a brilliant modern scholar transmigrates into a doomed noble lady's body, she refuses to accept her cannon fodder fate.

But as she rewrites her destiny, she uncovers a shocking truth: her knowledge may be the only thing capable of saving this collapsing world from annihilation.
