When the Rules Descend: Others Fight to Survive, I Cultivate Immortality

(No harem, no clichés, no mindless antics, no System, a touch of Lovecraftian horror, spiritual qi revival story. Readers beware!)

This is a world where mysterious forces have returned.

The moon in the sky is square, and the world is shrouded in gray mist.

Rule One: Do not look up and stare directly at the moon. If you can't resist your curiosity, choose suicide.

Rule Two: Do not use Chinese, not even in your thoughts, or it will contaminate your mind and cause you to mutate.
