I Treat the Forbidden Door as a Canteen

Jia Hua was just an ordinary worker who was overwhelmed by life. A blank book appeared in his mind that only he could see. Until that day, the subway tunnel tore apart without warning, revealing a giant door leading to the unknown. After narrowly escaping, he thought everything was just a nightmare. But I didn't expect that this was the beginning of the nightmare. The blank book in his mind guides him on his journey to find the fatal trial. Strange events happened one after another around him, and what made his scalp numb the most was that one afternoon, his own shadow showed him a sinister smile that did not belong to him. When he smiled and told you the first truth, the nightmare had become a reality.
