[Apocalyptic natural disaster + technology + single female protagonist + shelter]
The end of the world is coming, and the world has plunged into an extremely cold ice age.
When 99% of humanity froze to death in despair in the snow, Luo Zian walked into the deep mountain underground fortress left by his grandfather and activated the shelter upgrade system code-named "Absolute Domain".
The temperature here is constant at twenty-three degrees. Fifty tons of rice, 30 tons of frozen meat, and 100,000 cans are stored here. The omnic factory here operates day and night, forager ants search for resources in the ruins, and weavers print exoskeletons and gauss rifles. And in the "National Memory" quantum storage array he just robbed from the devil's capital, all the data of human civilization is sleeping - from "Kao Gong Ji" to the nuclear fusion blueprint.
But he wasn't the only one to survive.
Deep in the wind and snow, the underground city of Kunlun Mountain in the Dragon Kingdom is still struggling to support tens of millions of survivors, and its resources are about to be exhausted. The "Garden of Eden" chaebol shelter in the Eagle Country discovered his abnormal heat source through satellites and began to covet the top-secret technology in his hands. The Sakura Kingdom retreated to the deep sea and was conducting inhumane human mutation experiments.
And the most dangerous enemy may be something that shouldn't exist - the X-09 mutant fungus.
Fortunately, Luo Zian never fights alone.
Gu Xingluo, a genius hacker on the dark web codenamed "Stardust", became his back-to-back comrade with his reason and talent. Their relationship is the most resilient symbiosis in the apocalyptic wasteland.
"The end of the world is not the end of the human story. It is the starting point of another civilization."
And this perfect shelter hidden deep in the Taihang Mountains is that fire.
