Ice Silkworms, as recorded in the *Classic of Poison*, resemble earthworms. They are about the size of a middle finger and have translucent, crystal-like bodies. Moreover, Ice Silkworms are inherently venomous. Their Ice Silkworm Poison is ranked as the fifth deadliest toxin and also serves as the bane of other poisons, having an effect comparable to that of the Ten-Thousand Poison.
Gu Qingli guessed that it was probably the effect of consuming the Ten-Thousand Poison.
Thus, Ice Silkworms are also known as the "ultimate poison." Besides their "ultimate poison" trait, another notable characteristic of Ice Silkworms is their "ultimate cold."
Consequently, those infected by Ice Silkworm Poison often develop a layer of ice on their bodies. If they don't detoxify in time, they'll either die from excruciating pain or be frozen to death. They will not survive longer than the time it takes for an incense stick to burn.
