Doomsday Game: Become a God by Hanging Up

[Decisive killing] + [Single female protagonist] + [Non-digitized real death] A white light swept across the world, technology returned to zero, humans were imprisoned within high walls, and alien beasts were rampant outside the walls. A doomsday game with life as the bet quietly begins. There is no resurrection or data panel, and each person only has three days to survive. The only way to survive is to hunt strange beasts and practice hard to become stronger. Fang Yun abandons warmth and kills decisively. He is not a virgin or procrastinating, and he is well versed in the law of the jungle in the last days. He accidentally unlocked the only idle core, which has six exclusive idle skill columns. Once the skills are inserted, they can be automatically practiced 24 hours a day, maximizing efficiency. While others practiced hard for several days, he surpassed them in just one sleep; he killed all the strange beasts that stood in his way; and when people's hearts were unpredictable, he struck back with thunder. In the crisis-ridden apocalypse, Fang Yun kills strange beasts and crushes powerful enemies along the way, transforming from a nobody into a doomsday powerhouse.
