The Demon Lord's Toxic Queen

Talia Sutton transmigrates as a cannon fodder female character, her engagement broken off. She binds with the 'Toxic Tongue System,' exposes the arrogant male lead, and turns her fate around. She unites the Three Realms' righteous forces to resist the Outerworld Demons invasion. Talia protects her father and friends, wins Demon Lord Rhys's affection, seals the Outerworld Demon, and brings peace to the Three Realms.
