When An Jin first arrived in the Beast World, she had detoxified Ling Hong, which gave her a rough idea.
Gu Yin's venom was likely a highly potent and lethal concoction, primarily composed of neurotoxins.
Against any Beastman below the Fifth Rank or any ferocious beast, as long as they had even a minor wound, a single drop of his venom from her would be enough to wipe them out.
The number of beings who could rival Gu Yin's power was practically zero. If she were unlucky enough to encounter one, it would simply be her time to die.
Gu Yin took the small clay vial from her hand and transformed into a giant python over ten meters long. He squeezed a few drops of greenish venom from his fangs into it, then shifted back to his human form and handed it to her.
An Jin saw that the inside of the vial had already been corroded.
