"Heaven Mysterious City!"
Clad in black combat suits and holding a slender combat knife, Sara Williams spoke with a somewhat grave expression, "Mr. Clark, before the outbreak of Doomsday, the population of Heaven Mysterious City was nearly ten million."
"Because of the massive population, it fell on the first day of the virus outbreak, becoming infested with countless monsters. A large number of terrifying creatures emerged almost immediately."
"Now, several years have passed, and that place might be even more terrifying than Hell. Last year, when the base's radio was still functioning, we received signals indicating the emergence of a Ninth Tier Overlord-level monster there."
Sherry's face also turned somewhat pale: "It's said that once a monster reaches the Ninth Tier, it becomes an entirely different, horrifying form, powerful like a demon."
