Absorption, Parasitic Amanita Fungus

"Travel to and conquer the Antarctic Secret Realm?" John muttered to himself as he looked at the class change quest displayed on the system panel.

The other world portal could appear anywhere on the planet with land, be it deserts, wastelands, or the frozen tundra near the poles. The highly adaptable monsters wouldn't miss any of these places.

Therefore, even Antarctica had the other world portal.

Antarctica is inhospitable to human life, with no permanent residents and temperatures that stay around minus 50 degrees Celsius. The only human presence there consists of international scientific research stations.

There aren't many staff stationed at the research base, with only around a hundred people or so. Most of them are scientists with limited combat abilities. Although there is a small security team, it consists of only a few members.
