The heroine has a rare "poison-ridden" physique. She is alive and will transfer her own toxins to spiritual beasts that are weaker than herself through breathing, contact, feeding, etc. Most spirit beasts cannot resist the toxin and will die directly, but those spirit beasts that "just happen" to have special physiques or whose evolution direction is suitable for the poison will undergo violent changes when the poison is released, thus showing terrifying combat power that far exceeds the upper limit of their bloodline. In order to save herself (to prevent the spirit beasts from being poisoned), the heroine was forced to learn all kinds of alchemy and medicinal herb knowledge to "prepare the antidote". As a result, she successfully cultivated legions of mutated ferocious beasts one after another. The more she tried to keep a low profile, the more outrageous the spiritual beasts evolved. In the end, a group of the strongest spiritual beasts in the world were all trained by the damn Poison King.
