Get the Fanatic System, I Am Scarier Than Ghosts

[Thriller + system + imagination + funny + no heroine + physical ghost exorcism + eight-door escape] The door to the horror world opens, ghosts invade the world, many countries fall, and humanity is in danger. Ghosts have committed various crimes against humans. "Now that I think about it, I feel very dissatisfied! Ghosts can do whatever they want to us humans, can't we humans also do whatever we want to these ghosts?" "Ding! You are a real punishment! Congratulations to the host for obtaining the Ghost World Madman System!" The female ghost who knocks on the door looking for her husband, the evil ghost baby who lodges in the mother's body, the evil projection ghost who eats students... He was extremely arrogant before meeting the male protagonist, but shivered after meeting him. Ghosts: Uncle police! We need to call the police, that guy is too scary! I got the ghost world madman system, which is more terrifying than the ghosts.
