In 2125, Blue Star's labor force was completely replaced by AI, and billions of people became an "idle group", relying on federal government subsidies to survive. In order to maintain the vitality of civilization, the world's chief AI "Blue Dream" spent three months creating the lord-type online game "Canglan Online", which became an outlet for mankind to regain the meaning of survival.
There is no innate talent in the game. All players start with bare hands as "village lords" and face the disordered ancient world: plundering by refugees and lack of resources are commonplace. Climate disasters and wild beast invasions are frequent. "Blue Dream" only has basic rules. Players' alliances, betrayals, and the rise and fall of territories are all based on strength and decision-making.
What is the so-called exit for human beings to regain the meaning of existence in Blue Dream?
