My Brother Turned into a Ghost, I Thought It Was My Wife.

(Changing marriage) (No system) (Don't like to enter by mistake) After death, Yunpeng did not go to the underworld as he imagined. There was chaos all around. Countless manic ghosts wander around. And he became one of them. Devouring became the only thing they could do. In order to "survive", Yunpeng did the same thing as them, devouring. After an unknown amount of time, it gradually became conscious, and the intersection of countless thin red lines made him think again.
