After the collapse of the future era, the earth was covered with rusted metal and floating stardust. The resource oligarchy has built a suspended city and fed the numb people on the ground with "nutritional ointment" and "hope broadcast" - betrayal is a survival skill, indifference is self-protection, and faith is a bargaining chip. Lin Yan scavenged in the ruins to make a living, but did not extinguish the light in his eyes like others. He watched his neighbors sell their relatives for half a piece of nutritional ointment, watched his children regard the oligarch's badge as a god, and watched the "rescue ship" as nothing more than a tool to screen out "useful people." He wrote down every alienation of human nature in his notebook, holding on to the clear pain in the wave of numbness, trying to find the appearance of the devoured "human" on the rusty ruins, even if this road had to face the light of swords and lies in the stardust.
