The forest was composed of thorny bushes whose leaves were covered with black-red mottles.
However, upon closer observation it would be discovered that the spots were actually small insects, thus forming that massively extended insect-infested area that caused arrivers to feel terrified.
Grimm took out a test tube and carefully collected a number of "mottle insects". They were only one-tenth of a human fingernail in size. Strangely enough, in addition to an oral cavity in the frontal part of their body and a black gland that secreted venom, their legs seemed to have shrunk and degraded into a sucker.
"Well, I've never seen this kind of creature before. Maybe I could explore them and see if its toxicity can be used in the toxin constitution-building practices later on." Grimm dropped the test tube into his space pocket as he was thinking about this.
