Overnight, the world became a wasteland. The mysterious "beacon system" arrives, guiding the survivors to all kinds of strange evolutionary "paths". When the old order completely collapses, the boundaries between morality and humanity become blurred, and only strength is the only criterion for survival.
Office worker Lin Mo accidentally awakened to the seemingly useless "Observer" path at the moment of doomsday. While others were making great progress on powerful paths such as "Berserker", "Elemental User", and "Mechanic", he could only silently record, analyze, and deduce.
However, in this cruel game of evolution, information and insight may be the key to ultimate power. Lin Mo relies on the extraordinary insight and logical deduction ability given by the "Observer" to analyze the truth of the doomsday step by step, discover hidden resources, predict unknown dangers, and even... Plan the evolutionary path of others.
When the mist of disaster envelopes the land, when mutated monsters roar, and when the darkness of humanity breeds in despair, how will Lin Mo, this inconspicuous observer, use his "beacon" to find his own way to the sky in this wasteland, and uncover the chilling secret behind the "beacon system"?
