Burning Rift

At the end of the 21st century, the earth has entered the "Eternal Summer Era". The climate is completely out of control, and the south has become a deadly scorching environment of 50-72°C all year round. The cities are melting and the air flows like lava. The north became the last refuge, an invisible "thermal wall" dividing the country in two. The strict "Northern Migration Quota System" determines life and death based on wealth and contribution points. The rich hide in constant-temperature domes and enjoy phase-change skin suits and heat-stabilizing genes; but the hot people at the bottom are struggling with soaring prices and failed cooling patches, and may be "steamed" by high temperatures at any time. Lin Chi, a low-level maintenance worker, accidentally activated the experimental "neuro-phase change chip" and gained the power to resist high temperatures, but it also became irreversibly "thermalized." Northern Dome elite analyst Su Lin gradually wavered in the cold algorithm. When a super heat wave sweeps across the south, the two men's secret cooperation across the heat wall ignites the weak fire of resistance to class solidification and climate apocalypse.
