The Eldest Daughter of the Tang Clan of Sacheon Protects the Family

Tang So-hwa is a prodigious poison master whose encyclopedic knowledge of every toxin beneath the heavens has earned her the fearsome title of Mandokhaesa—the Master of Dissolving All Poisons. As a daughter of the illustrious Tang clan of Sichuan, her marriage to the head of the rival Namgoong family was meant to cement an unbreakable alliance. Instead, it became the instrument of her utter ruin. Betrayed by the very husband she trusted, So-hwa watches in horror as her own bloodline is systematically annihilated at the Namgoong’s hands, leaving her the sole, grief-stricken survivor of her clan. With nothing left to lose, So-hwa transforms her sorrow into a weapon of absolute retribution. She unleashes a cataclysmic poison upon the Namgoong sect, decimating every last member in a single, devastating purge. Her vengeance fulfilled, she swallows the same deadly concoction, closing her eyes to welcome the eternal silence of death. Yet instead of oblivion, she awakens with a sharp gasp—seventeen years old once more, standing in the radiant, thriving halls of the Sichuan Tang clan at its golden peak. The memories of slaughter, betrayal, and her own suicide are seared vividly into her mind, but so too is the arsenal of deadly knowledge she wielded in her past life. Now, with the face of a girl and the soul of a relentless avenger, So-hwa must navigate a treacherous path: protect her family before the shadows gather, confront the man who will one day destroy her, and decide whether to simply survive the coming storm—or poison it at its very source.
