When an eerie fog engulfs the Jiuzhou Continent, cultivation stops working. The once lofty masters of the immortal sects are no better than ants before these incomprehensible rules. Some are strangled by their own shadows, some are trapped forever in the same day, and some melt into pools of blood after giving the wrong name.
Shen Ye, the most useless odd-job disciple of the Tianjian Sect, had planned to end his pathetic life of ten years stuck at the third Qi Refining level by jumping from a cliff. But the moment the fog descended, a mark from the distant past chose him, granting him eyes that could see loopholes in the rules.
From then on, he walks the cracks between the rules, using them to slaughter the eerie beings while gradually losing his humanity. When the truth behind the fog comes to light, he learns that the entire Jiuzhou Continent is merely a game board for a higher-dimensional civilization, and that the so-called path to immortality is no more than ants trying to climb a branch. Shen Ye makes his choice:
If there are no immortals in this world, then I will become the eerie itself.
