The people who were screaming were those Mutators whose level of Base Mutation was relatively low, their carapaces unable to completely encase their bodies.
The robes on everyone's bodies swiftly decayed into tatters in the liquid due to acid corrosion.
At spots where the carapace lacked protection, the liquid corroded their flesh as if it had come into contact with concentrated sulfuric acid.
Those with a higher degree of Base Mutation, fully encapsulated by their carapaces, fared slightly better, but that was only true for those at the Crystal Base Level.
For those at the Alloy Level, their Alloy Carapaces bubbled up on the surface when immersed in the liquid, showing signs of corrosion.
Lin Shen's carapace was only at Steel Level, which surprisingly held up almost as well as the Alloy Carapace in the liquid, showing only minor signs of corrosion, and wouldn't be breached anytime soon.
Fortunately, among the Mutators who came this time, only Lin Shen was at the Steel Level.
