The immortals and demons have been at war for thousands of years, and the isolated All Souls Training Institute is one of the few peaceful pure lands in the entire star field.
A sudden massacre broke the peace, the barrier was tightly closed, and the murderer was hidden among the demon cultivators. The protagonists are involved in a series of mysterious cases, murders occur one after another, suspicions of various ethnic groups abound, and civil strife continues to ferment. As layers of clues cleared up the fog, all the fairies and monsters realized that all the killings were traps. The remnants of the demon clan, which had been dormant for thousands of years, were using the chaos of the murders to plan a shocking conspiracy that could overturn both the fairy and monster worlds.
