Programmer Lin Shen was on the last subway train when he saw a woman with no facial features. The next day, the face grew on the back of my colleague's head. Lin Shen was forcibly sent to Qingshan Mental Hospital, only to find that the lunatics here were the real sane ones - they could see the "god" parasitic in human consciousness. After hunting the God for the first time, black lines appeared on the back of Lin Shen's hands, at the cost of a continued decline in his sanity. He formed a team of patients and discovered that his mother was once the world's most powerful divine hunter, and the truth about the S-class god's "old days" would overturn his entire understanding of reality. When madness became the only way to wake up, Lin Shen chose to actively embrace the abyss.
