陈源知道自己如果把真相说了，父母和弟弟一定会竭力劝他一起离开珈蓝星，但他还不想走，一来，他还想去火种窟下的地下洞窟寻找火晶石，二来，他觉得留在珈蓝星他完全恢复记忆的可能姓要大很多。An unlikely trio traverses a desert planet in search of a rumored lake- and the hope for a better life that it represents. Lernert travels across the barren landscape, digging through rubbish piles in an attempt to build a body for Susan, the robot head who hangs, unresponsive, from the back of his pack. The pair comes across Rola, a spirited twentysomething, who lacks survival skills but makes up for it with sheer determination. At first unwilling to travel together, the three-some navigate the harsh desert in search of a mythical water basin that can replenish their depleted resources and their will to continue.
