The Classic of Mountains and Seas I Just Wrote

My name is Pu Budi. I'm nineteen, and I can see ghosts. When my mother died, she left me a book with blank pages. I write in it with my blood, and whatever I record can be summoned: mountain demons, fox spirits, wandering ghosts. They all squat inside my book. I thought I'd spend my whole life chatting with ghosts in the village, but then an admission letter from Jixia Academy came flying right at my face. On my first day at school, I met two people. One was Sun Tian of the Medical School. She was pretty and came by every day to take my pulse and bring me medicine, saying I was short on qi and blood. The other was Qin Ren of the Mohist School. She barely spoke, and whenever I messaged her, she'd reply with a single “Mm.” But the night I was cornered by the latrines, she took down more than twenty people all by herself. Later, I found a dying nine-tailed fox on the back mountain. It was twelve thousand years old, male, and moved into my book, where it complained all day long. Later still, I pushed the son of Qingzhou's richest man off a cliff. He died, came back to life as a vengeful ghost, and possessed an ancient calamity beast. Now that thing is heading for the academy's camp. And my book is also home to a twelve-thousand-year-old fox spirit, a pig that brings good luck, and, some three-eyed deity. They say I'm a descendant of Boyi. But all I want to ask is: after this fight, can I make fewer trips to the latrine?
