These potions were one of the medications Zhiyan had often researched in her past life, somewhat similar to strong acids and bases, only their reaction speed was slower and the duration lasted longer. Not to mention human skin, even a rock could be dissolved by it.
In the past, she had dabbled in them for fun, but this time she was using them for self-defense. After all, she was still young, the world was vast, and anything could happen. Relying too much on the Qiankun Space would only expose herself sooner. Rather than evade, it was better to confront head-on. Who said fighting had to rely on brute strength?
With these potions, let alone Mid-level Sages, even if Advanced-level Sages came at her, she wouldn't be afraid. (Of course, the precondition was acting before they could react, as throwing the potions onto someone was a skillful task in itself.)
