Capítulo 604: Betrum Hypothesis

 "How sure are you of the presence of the existence of S-rank Monsters?" Calle might have yelled, but she believe the situation deserved it.

 After all, a researcher had admitted the possibility of there being an S-rank monsters in Zell Forest. As strong as she is, Calle knew she did not hold a candle to S-rank, monsters or human. They would trample over her without realizing her existence.

 "We are not completely sure. But, the possibility of there being an A-rank Human Bug make us recognize the possibility of such monster to exist in Zell Forest." The old researcher replied.

 Calle let out a deep breath. At the moment, it's just the worst-case scenario, an assumption made by researchers due to the possibility of there being A-rank Human Bug. A high possibility considering the number of C-rank Human Bugs.

 As she give it a longer thought, she realize the possibility, while exist, is highly unlikely.
