The world was strangely rewinded.
Folk taboos that were once regarded as ignorant and superstitious have become the cruelest rules of survival; urban legends passed down from word of mouth have become real nightmares that prey on people. There are no warnings and no records. The deserted areas known as "dangerous areas" are like the scars of civilization, quietly growing and spreading in the city.
Guns and artillery fail here, and common sense collapses here. The surviving people can only grope for the absurd and deadly "rules" in blood and dance on the tip of the knife in exchange for a chance to breathe.
Until someone discovers that behind the extreme fear, there may be a trace of "understanding"; and if you want to end the weirdness, you may have to first step into that forbidden place, get a glimpse of its origin, and even... Control its power.
This is a single-plank bridge full of thorns. Those who go forward will either become the torch that illuminates the future, or they will become new weirdness themselves.
However, when you gaze into the abyss, the abyss gazes back into you.
When the anchor that holds reality is loosening, are we saving civilization, or are we accelerating its end?
And when everything is silent and you finally have the power to fight against the strangeness, you realize the ancient adage: Yin is within Yang, not the opposite of Yang. What is reflected in the mirror, is it you who upholds righteousness and punishes evil, or is it... It that steals its true face?
