Nanomancer Reborn - I've Become A Snow Girl?

A failed alchemist, bound to a wheelchair, finds herself dragged into the heart of the enemy’s fortress. Unable to walk or fight, she’s dismissed as harmless—a fatal mistake. With nothing but her sharp mind and forbidden knowledge, she turns captivity into a deadly laboratory. Every guard becomes a test subject, every locked door a puzzle. They think they’ve trapped a victim. She plans to show them what a true villain looks like when she has nothing left to lose. A dark, strategic fantasy of revenge, resilience, and ruthless intellect.
