The apocalyptic age of extreme cold arrives without warning. In his previous life, Lin Shi was betrayed by his girlfriend and best friend, who joined forces to murder him. By a twist of fate, he is reborn three days before the apocalypse and unlocks his ancestral treasure basin, which can duplicate supplies without limit. He immediately sells all his assets and stockpiles plenty of cold-weather gear, medicine, and weapons, then builds an impregnable safe house. When the deadly cold wave strikes, he calmly defends his territory against former enemies seeking to plunder him and greedy neighbors. Along the way, he rescues the sisters of Su Qingyan, a female doctor who once saved his life in his previous existence, and gathers trustworthy companions to establish a benevolent refuge called "Kindling." Staying true to himself, Lin Shi settles scores with the wicked and uses his strength to protect everyone, creating a warm and secure sanctuary amid a frozen, chaotic world.
