In the third year of nuclear winter, Chen Yu, who was wandering in the frozen wasteland, accidentally activated the "fishing system". Wherever the fishing rod pointed, he could fish out mutant crystal nuclei, apocalyptic materials and even lost technology from the "doomsday fishing pool". He counterattacked from a scavenger to become the hope of mankind, leading the survivors to fight against the devouring ice, the tide of mutant beasts, and the power struggle in the underground base. He finally fished out the satellite logs of the old world, uncovering that nuclear winter was actually the conspiracy of the alien civilization's "Ice Screening". In the end of the world, he used a fishing rod to fish out an antimatter engine and open up a new home for mankind.
