It is actually a story of survival in a cruel world. A complex position gave birth to belief... The story is set in the distant future... A world where physical rules, common sense and inherent values have collapsed... After the "Seven Strings Split the World", threshold organisms with survival capabilities and adaptability far beyond humans were born, standing out from extreme environments where most creatures cannot survive. In order to survive, human beings chose to cooperate with the liminal organisms, using sefirot to open up four zero domains (i. E., Zero-sum domains) in the wilderness, and re-established different social systems. Feng Bai was born in the Central Zero Region, where the social status of the Threshold Body is low. Because of his special status, he was forced to flee his hometown and come to the Western Zero Region... He returned to the Central Zero Region 8 years later... Is the conspiracy of the Central and Western Experimental Subjects to commit collective suicide really an accident? Faced with Tong Shuo, who is in a similar situation to his former self, what choice will he make? Who will save the soul trapped in the wind... Icarus's melted wings...
