Metropolis: I Have a Demon King's Notebook

When he was on duty again, Zhang Haoyang picked up a notebook made of unknown leather. After he picked it up, the classmates who saw the note with him did not remember it. But when he saw that the notes described various ways to speed up spiritual practice in order to escape from the Three Realms as soon as possible, he panicked and eagerly wanted to find someone to express his fears. But at this moment, he discovered an even more terrifying thing, that is, no one could see the notebook he was holding. This was not the most desperate thing. What made him even more frightened and helpless was that after he followed the first step in the note, what he felt was no longer the gentle laughter of his classmates, but full of hostility. This hostility was somewhat inexplicable. As time went by, things were getting worse. This novel and its characters are purely fictitious.
