Doomsday Survival Quota

[No system, no harem, hard-core survival, realistic enhancement] On the night shift when the nuclear explosion occurred, 19-year-old miner Yu Ling was trapped underground. The main fan can still run for a maximum of seventy-two hours. More than 300 people are waiting to escape. However, the mine's powerful forces have sealed the wellhead and sent all diesel, medicine and filtered air to the private refuge floor, but there are only twenty places left there. During a rescue, Yuling found that her wound began to stop bleeding abnormally, but what followed was high fever, palpitations, and insatiable hunger. Some people died from the radiation, some remained unchanged, and some began to strengthen their bodies like him. But strengthening does not mean surviving. Without clean water, protein and medicine, it will only lead to a more painful death. In this wasteland separated by nuclear fallout, severe cold and famine, the rules of survival seem to be the same for all life.
