In 2157 AD, radiation dust enveloped the broken city. Jiang Yirran's spiritual roots were dug up alive by the Taoist "Tianyan Sect" and thrown into the ruins where mutant beasts were rampant like garbage. In the third year of making a living by picking up radioactive debris, he accidentally saw the thread of karma above everyone's head - the good ones had good luck, and the evil ones had impending disaster hanging above their heads. He used a fairy grass that can mutate in radiation as bait, so that the overseer who framed him back then was backlashed by his greed, and his karma detonated a radiation thunderstorm, exploding into a source of pollution. As the news spread, major cultivation companies rushed to woo him, but their enemies sent killers to secretly encircle and suppress him. Ling Zitang brought the fragments of the lost prescription, but Monk Huiji revealed the truth: the law of cause and effect is not a gift. Every time a person is judged, one more fragment of the spiritual root in his body will be cracked. When the catastrophic clouds of nuclear radiation gathered over the wasteland and formed a world-destroying whirlpool, Jiang Yiran discovered that only by using himself as the anchor of cause and effect and directing the karma of the entire city towards the catastrophe, could he gain a glimmer of hope. But he only has one last chance for trial. To kill enemies? Or save this damn world?
