In 2149, the "end of resource depletion" has arrived, and 99% of the world's land is covered in abandoned garbage. Human beings huddle in the only 12 "steel fortresses" and survive on limited distribution of synthetic food.
Just when everyone thought civilization was about to end, a global "Doomsday Survival Live Broadcast" suddenly popped up - in the camera, Lin Ye, who had just been driven out of the fortress garbage dump, was squatting in a mountain of scrap metal, casually picking up a piece of rusty iron.
[It has been detected that "star core fragments" can be recycled and converted into first-level energy, which can survive for 10 people for a week]
The live broadcast room exploded instantly: "Is this a special effect? Or are you crazy? Can picking up garbage be exchanged for energy?"
Immediately afterwards, Lin Ye picked up another broken plastic bottle, and the system prompt sounded again: ["Mutated plant seeds" detected, which can produce pollution-free fruits and vegetables after cultivation]
While the dignitaries in the Steel Fortress were still fighting over half a piece of synthetic bread, Lin Ye had already used the "garbage" he had picked up to build greenhouses in abandoned areas that could automatically purify the air, alloy houses that could withstand sandstorms, and even dug out an "old world technology library" that had been forgotten for hundreds of years.
Later, when the battleships of alien civilization arrived, humans discovered that what Lin Ye picked up was not garbage, but the last hope to save civilization. And that live broadcast, which was ridiculed by everyone, has long become the "record of human redemption" watched by the whole universe.
