At this moment, Su Lin and the Purple Lynx had reached the Arctic Borderline!
As soon as they entered the Arctic Borderline, they were detected by the radar of the Defense Force.
On the radar's display, the life signals and energy fluctuations caused by their collisions exhibited by Su Lin and the Purple Lynx both exceeded the detection range of the highest-end radars.
All had broken through SSS!
An SSS-tier designation within human society is equivalent to a high king-level mutant creature. Surpassing the SSS-tier rating implies at the very least an extreme king-level, or even reaching the apocalyptic level!
What does the apocalyptic level mean?
Apocalyptic level mutated creatures have essentially broken free from the constraints of carbon-based life forms, and they are no longer something that modern human weaponry can restrict or defeat!
Such level of mutated creatures are the strongest overlord-level presences in various regions!
