Not long after his abilities awakened in childhood, he somehow lost his spirit animal in a muddle, and with it, his Guide powers.He could no longer fulfill his dream of joining the military, so he settled for the next best thing—becoming a worker at a green vegetable farming base, responsible for delivering produce to an upscale sanatorium affiliated with a certain Federation legion.One day, Qiao Ran stumbled upon a stroke of insane luck: he found an ownerless spirit animal—a huge white lion.Though this big white lion wasn't the sharpest tool in the shed, its fur was soft and petting it was pure bliss. Its abilities were top‑tier too. One deep sniff of it felt like taking a miracle tonic—his headaches vanished, his back stopped aching, and from then on, Qiao Ran lived a self‑sufficient, happy little life.Until, days later, the lion's owner showed up at his door—a neurotic, mood‑swinging man. And Qiao Ran's good days came to an end.Before:Qiao Ran: “Can I borrow your lion for a quick rub? Just one little rub!”The man: “Ugly?
