The protagonist is an alchemy apprentice who has a damaged Dantian and is regarded as useless by the whole clan. When others use spiritual energy to practice elixirs, she can only rely on the "Soul Medicine Cauldron" to refine the body-tempering poison elixir that suits the taste of monsters. Her golden fingers can not only sign a soul contract with monsters, but can also poison the enemies while causing the beasts to evolve crazily. The real counter-routine is that others make elixirs to save people, she makes elixirs for beasts to eat, others rely on their strength to tame the beasts, and she relies on "drug addiction" to keep the monsters from going away.
