Wen Wen asked in astonishment, "With so many monsters having escaped, and possessing such strong capabilities, it makes no sense that we haven't heard a peep until now."
The man in the metal suit chuckled and said, "The Sanctuary back then wasn't as benevolent as you are. Those monsters that managed to escape are probably afraid to reveal their true identities."
Thinking it over, Aker Aru, though he had roamed the world for a thousand years, indeed always kept a low profile.
Moreover, from the way he reacted with shock and anger mixed with a hint of fear upon discovering Wen Wen was a Containment Officer, one could probably guess how terrifying their experiences had been back then.
The thought of dozens of enemies lurking outside, eyeing the Sanctuary, made Wen Wen's scalp tingle.
