The Mu Yun Small Seal Script was created by the ancient eccentric Tang Muyun. Many of its characters have been completely lost. Anyone ordinary who reads it will have their vital essence, energy, and spirit drained away, forming a special spirit body. Such a spirit body is called a Curse Vessel. One night during their senior year of high school, the sleep-deprived students in Dorm 305 gathered to tell ghost stories. They could never have imagined what would happen because they stayed up past midnight.
