A top-secret file numbered "X" is locked in the archives of the psychological clinic.
Anyone who opens it will gradually develop the same symptoms: paranoia, auditory hallucinations, and an uncontrollable imitation of the death of the previous reader.
Intern Shen Du did not believe in evil until he discovered that his case records had been written into this file by a manual pen three years ago.
"You finally turned the page."
The handwriting on the last line of the file was exactly the same as his.
Intention: When destiny is written in advance, the only way to break the closed loop is to first see clearly who "the person who wrote it" is.
