The Retired Hero is an Extra - Chapter 186 - : Beneath the Surface

The world is in ruins. Extreme sub-zero temperatures suffocate the surface, making even simple survival an ordeal. Frozen derelicts of bygone eras span across massive ice wastes. And the survivors closely guard any technology rediscovered within.The only escape from the deadly climate is beneath the surface. But it’s another disaster underground. Monstrous machines lurk in the depths. Unhinged demigods war against them, dying over and over, treating it all like a game. The land itself shifts over time, more contraption than rock. And an ominous prophecy states that the key to everything waits on four heroes - but nobody knows who or where they are.When an expedition into the far uncharted north goes terribly wrong, Keith Winterscar and his father get trapped together in a desperate fight for survival. Stumbling upon an ancient war of titanic scale; the two will need to set their differences aside while they struggle against Gods, legends, and the grand secrets of the realm that lies below.
