Weird Rules? Isn't This My Alma Mater?

(Not a brainless cool article + logical reasoning + single heroine + two strong characters + half-group portrait) This is an old high school that has stood tall in the world of strange rules and stories for a long time. Today, it welcomes a special group of students. Will what awaits these students be complex and cumbersome rules, or cruel and terrifying ghost stories? … My name is Liu An. As you can see, I ended up in this weird school by accident. The rules written in blood and the gazes of terrifying beings all reminded me of the weirdness and horror of this school. The "gardener" who plants students in the soil, The dormitory manager who knocked on the door in the middle of the night and demanded his life, The school doctor who seeks wealth and murder. Everything reminds me of what kind of world I am in. However, this school is so much like my high school alma mater. Every corner of this school is similar to what I remember. Even the teachers in the class are familiar faces. Why is this? … You are from Kyushu, Rule gossip is your enemy! … (This book has a complete world view, and the connection between rules and strange stories, as well as the existence and categories of the rules themselves, will be presented one by one in the book.)
