Weird Recovery: My School of Ghosts Has Unlimited Upgrades

[Strange recovery + invincible flow + ghost school management + decisive killing] What is it like to travel to a ghost school filled with blood mist and take classes with fifty-three ghost classmates? Lin Jin said: Thank you for the invitation. I am in a ghost school and have just become the principal. I feel good. He was trapped in a time loop at the beginning, and just when he was about to be driven crazy, the [Thriller Campus System] was activated! But the first task made him dumbfounded - within twenty hours, kill the current principal and take over himself. Facing the terrifying principal composed of rotten flesh and resentment, Lin Jin knocked him to pieces with a backhand punch! From then on, this ghost school's surname was Lin! While other players were still screaming for escape in the dungeon, Lin Jin already regarded them as mobile experience packages that provided "thriller value". Other players are still trying to find ways to defeat the female ghost, but Lin Jin has already captured the stunning ghost bride as a music teacher, forcing her to sing with tears in her eyes. Other players are still looking up to the beautiful boss, but Lin Jin has already asked the top beautiful players in the server to wear black silk skirts, act as a teaching director for him, and encourage the ghost students to study hard! Upgrade the campus, expand the forbidden area, and annex other copies! The midnight slaughterhouse serves as the canteen, and the Internet addiction treatment center serves as the confinement room! Lin Jin's goal is to open branches of Changming Ghost School in every scary world! "Attention all players, welcome to my school. If you are disobedient... Please stay forever."
