Crimson Tide Elegy

In 2585, the earth's orbit shifted, and the northern hemisphere became a "dead light zone" - year-round high temperatures, strong radiation, and ultraviolet rays exceeded biological limits. Human beings migrate south or go underground, social order collapses, resources are monopolized, and classes are solidified. The northern hemisphere became an abandoned "scorched earth zone", and the southern hemisphere established the "New World Federation", with the "nine major families" controlling everything. In order to continue their genes, human beings have opened "gene locks", triggering disordered evolution, and some people have awakened supernatural powers.
