Forty-five students from Class 1 (7) of Jiangcheng No. 3 Middle School were drawn into a life-and-death red envelope group from which they could not exit during an ordinary self-study class.
From the first midnight selfie mission, death follows. The rules are cruel, the tasks are strange, and ghosts are around. Human nature completely collapses in fear.
As the number of deaths in the class fell below half, the red envelope swarm swallowed up the neighboring classes like a plague, swept through the first year of high school, and spread throughout the school. Three thousand teachers and students became the nourishment of the evil formation.
