Extreme Cold Descends: I Power Up When Near Death

A sudden unknown extreme cold disaster strikes the globe, temperatures plummet, and prosperous cities freeze into hellish wastelands overnight. In his past life, Lin Chen endured five years of the frozen apocalypse, but due to his kindness, he was stripped of all supplies by acquaintances and died miserably in the snow, his body buried under ice. Reborn on the third day of the extreme cold, he has no system but possesses a talent for explosive power-ups in desperate situations—the closer he is to freezing to death, the more his physical strength surges, at the cost of suffering from cold poison with each burst. The frozen dead begin to mutate into ice-zombie monsters that hunt the living; former neighbors turn on each other, fighting over scraps of supplies. Compassion leads to death, kindness brings no survival. Lin Chen discards all mercy, using his past-life memories and desperate abilities to fortify bases, scavenge supplies, and build a survival team. He fights off mutated monsters, crushes sieges by raiders, and carves a bloody path to survival in the frozen wasteland at minus a hundred degrees. — Description from novelcodex.org
