Gray Sea Era

In the ninth year after the disaster, Gu Yanqing, a Gray Contractor, was scavenging in Linyuan City to survive. After saving a White Tower military doctor who carried the key to "Reverse Gray Contraction", he was involved in the struggle between the White Tower, the Research Institute, the Lantern Mother Society and the floating platform on the sea. He traced the truth about the accident between his father and Erspora, and finally had to make a choice between "rebuilding order at the expense of a few people" and "fighting for the survival qualifications of the Gray Contractors".
