This story not only follows the daily routines of the Great Wall Guards and the Protectorate but also portrays life in the Cloud Desert through the eyes of characters from various factions. Whether it is the Great Wall Guards posted at the border, the caravans that steal from the rich to give to the poor, the ancient people whose homeland has lain barren for centuries, or the down-on-his-luck prince wandering far from home, each person has a territory they must defend—to safeguard peaceful lives, to protect one another's dreams, to preserve lost cultures, and to shield the people of their native land.
Though one individual's strength may be limited, their shared conviction to protect each other makes them unbeatable. It is this very belief that allows these former strangers to appreciate and care for one another, gaining a "precious treasure" that goes beyond material wealth.
