Solar flares erupted, global temperatures soared to 70 degrees, the earth's surface became scorched earth, and human civilization collapsed in the extreme heat. In his previous life, Chen Rui was betrayed by his fiancée and his close friends in the Oasis Refuge. His blood was drained in exchange for clean water, and he died tragically in the desert. After being reborn and returning to the 30 days before the disaster, he awakened the "Quantum Folding Space" and immediately emptied his former employer's super-large industrial and survival material reserve. While the former betrayers were killing each other under the scorching sun over a mouthful of stinky water, Chen Rui was sitting in an air-conditioned room made of special alloy, eating ice-cold watermelon and watching this hellish game with cold eyes.
