Shattered Echo

The air here always smells burnt, like ten million damp copper wires thrown into an incinerator. Chen Feng, a scavenger who survives in the ruins of the Gray Realm, lives a rat-like life in this place strategically abandoned by the federation. Until one day, in order to earn 500 ration points, he accepted a seemingly ordinary mecha recycling commission. He dug out a silver crystal fragment from the rusted cockpit, which triggered a strong resonance in the crystal in his chest, an organ that evolved with human beings. In this huge world that relies on the echo synchronization system to maintain operation, because of this unexpected contact, the long-blocked noise began to be heard. This is not a gift, but the beginning of a disaster. The hunter's guild's tracking bombs arrived immediately, and the guardian network covering the entire territory marked him as a "discordant" who must be eliminated. In order to survive, he had to escape into the war zone that was considered a desperate situation to find a glimmer of hope. As the escape deepened, he gradually discovered that he was not only a fugitive, but also the key to some ancient secret that had been sealed for five hundred years. "This weak 'echo' not only broke the five-hundred-year-old physical balance, but also inadvertently restarted the ancient calculation about how civilization can hide and survive in the universe."
