American Rules Apocalypse

The morning sun illuminates the land of America, and an impenetrable transparent barrier appears on the border of the United States. Within the barrier, the rules of death are coming one after another. Rule 1: [After 48 hours, participants whose location is below 2,000 meters above sea level will die] [Participants whose altitude is higher than 4000 meters are immune to Rule 2] How can we avoid chaos when everyone is armed with a gun? Oliver was given a recorder badge, which made him immune to the rules as long as the video he shot garnered enough views. Carrying a camera, Oliver walked on the edge of the rules and recorded various scenes of the end of the world. However, these rules of death are just a game played by the gods.
