Strange Recovery, I Am the Master of the Rules of the Nightmare World

[Imagination, horror revival, not brainless, the plot is a bit slow, there is no heroine, please enter with caution] In Blue Star 2061, the third gray fog zone appeared, and nightmare events exploded. Lin Xuan became the first person to walk out of the core of the gray fog zone alive. Ordinary domestic cats peel off human skins, melon farmers' fields are filled with heads, and strange kilometer-long beasts devour limbs. The forbidden magic box has been completely opened, and all kinds of strange things have enveloped the whole world. In the dark ages, human lives were like grass and chaos became the main theme, but K City remained in order.
