Seven Days Ghost

During the three years that Hongyan stayed in prison, an electronic virus called "ghost" appeared in society. There must be a more attractive story behind the "ghost" - many boring people are willing to believe this, so they weave all kinds of interesting legends about the "ghost". It wasn't until Hongyan was released from prison three years later that he discovered that most of these legends were true! At the same time, the incident that Hongyan thought was over in his hands three years ago is still not over yet... This is a short essay, please forgive me for the short word count.
