In the third year after the apocalypse, Song Qiji, a loser survivor who was abandoned by his teammates, accidentally activated the "Wasteland Recycling System". With the golden finger that can decompose everything (zombie crystal cores, mutant beast skeletons, abandoned machinery) in exchange for resources, he gradually counterattacked from an ant huddled in an underground garage to a recycling king who controls the lifeblood of the wasteland. In the early stage, the system relied on crushing materials to defeat old teammates. In the mid-term, it established a "Spark Base" to fight against the tide of mutant beasts and ambitious forces. In the later stage, it uncovered the mystery of the origin of the apocalypse, used recycling capabilities to reconstruct the fire of civilization, and finally became a "living ark" for mankind in the wasteland. The cool points focus on the real-time feedback of "garbage turned into resources", the crushing counter-kill, and the strategic battle of wits in base construction.
