"Nation-destroying level..."
Those three words dealt a heavy blow to Lu Xin's heart.
No matter how one looked at it, Lu Xin could no longer be considered a newcomer to the Special Pollution Cleanup industry. Naturally, he knew what such classifications meant.
Generally speaking, Ability Users who only handled sudden outbreaks of special pollution within High Wall City usually encountered pollution events ranked at most from Level One to Level Four. Broadly speaking, these corresponded to Ability Users' D, C, B, and A ranks.
But just as an Ability User's powers became impossible to predict once they reached S rank, the same was true of special pollution.

Special pollution exceeding Level Four likewise often represented a threat whose extent could not be calculated or expressed through data.
Thus, several bloody terms had emerged.
City-slaughtering level.
Nation-destroying level.
These terms for the various levels all carried an intuitive and weighty meaning.
City-slaughtering level meant special pollution that, if allowed to develop freely, could engulf an entire High Wall City within a short period.
Nation-destroying level referred to special pollution capable of destroying an entire nation.
Of course, this kind of special pollution did not necessarily mean that the Pollution Source possessed enough power to destroy a city or nation in a single breath. Special pollution was still special pollution; its manifestations were always complex and diverse.
For example, city-slaughtering level could refer to pollution that suddenly erupted with enough force to destroy a city and could not be stopped.

Lu Xin had only paused slightly and
