Extreme weather has swept the world, turning the land into an endless sea of sand. Freshwater resources and energy have become the lifeblood of survival. The Iron Bone Tribe, a desert nomadic tribe, relies on the mechanical technology inherited from the old era to search for abandoned energy stations and water purification equipment in the sand sea to survive. When the mining team of the giant Tianqiong Group broke into the territory and coveted the geothermal energy core buried deep underground, Jin, the leader of the Iron Bone Tribe, stepped forward. His mechanical prosthesis is not only a powerful weapon, but also a key to the equipment of the old era, which can awaken the sleeping defense machinery. As the conflict escalates, Jin realizes that the Sky Group's ambitions go beyond energy plunder - the AI behind it attempts to build an energy monopoly hub, screen out "high-quality humans", and push all nomadic tribes into despair. In order to protect his homeland and the hope of survival, Jhin embarked on the road of uniting other oppressed tribes to form the Sand Sea Alliance, vowing to crush Tianqiong's conspiracy and open a way for the nomads in the Sand Sea.
