The end of the world has come, order has collapsed, powers have awakened, and survivors in the wasteland are struggling to survive. Lin Mo was unexpectedly reborn three days before the disaster with the memory of ten years of struggle in his previous life. He originally wanted to rely on the "waste recycling system" to store goods in a low-key manner and live a stable life. However, the tasks issued by this system became more and more serious, forcing him, a salty fish who only wanted to collect junk, to be a savior candidate. While others are competing for food, territory, and superpower crystal nuclei, Lin Mo's worry is: Which S-level dangerous place should he go to "collect scraps" today? And how to make the big bosses who are chasing after him to redeem the "waste" understand that once the goods are shipped, they will not be returned or exchanged unless... More money is added.
