Age of Fog: Guardian Ball

Prologue: The Gray-Green Era That year, the world died. An ecological disaster that no one expected swept the world overnight. Gray-green deadly poisonous mist spewed out from the cracks in the earth's crust, laden with neurotoxins, mutated spores and industrial corrosives, dyeing the sky into eternal silence. If any living thing is exposed to the fog, within three minutes, its lungs will fester, its nerves will become completely necrotic, and its genetic chain will disintegrate into dust. In seven days, just seven days, 99% of human civilization collapsed. Cities have been reduced to ruins, oceans have become poisonous pools, forests have withered into scorched earth, and the once noisy planet has fallen into deathly silence. In desperation, the remaining global coalition government adopted the most cruel and only self-rescue plan in human history - a global nuclear purification plan. Launch hundreds of high-temperature purification nuclear bombs to completely burn, crack, and reset the entire surface contaminated by poisonous mist. All toxins, mutants, and pollution sources will be reduced to nothingness in the nuclear flames. The price is that surface civilization will be completely reduced to zero, and humans must hide in an absolutely safe barrier and survive for three hundred years, waiting for the earth to regenerate clean air, water and soil. And on the entire earth, there is only the last piece of land that is not infected by the poisonous fog - Qingchuan Town. My name is Li San, and everyone respects me as Dr. Li San. I am the top quantum energy and barrier technology researcher in Qingchuan Town, and the last hope for human civilization.
