Apocalyptic Wasteland Simulator Novel

Chen Pingchuan, stranded in an alternate world for three years, unexpectedly receives the Apocalyptic Wasteland Simulator. Through the simulator's forecasts, he discovers that Spring City faces imminent catastrophe within the next year. The disaster will bring intensely radioactive red rain and spawn dangerous mutated creatures known as Black Demons. While the simulator grants Chen a significant survival advantage, he becomes increasingly determined to uncover the true identity and purpose of a mysterious girl he encounters within the simulation. The girl leaves behind only two cryptic items: an unmarked bottle containing liquid of unknown properties and a hastily scrawled note bearing just two urgent lines. The note reads: "Avoid the red rain!" and "Forget me!" These cryptic messages hint at deeper mysteries surrounding the simulator itself and the girl's connection to the impending apocalypse, driving Chen to seek answers amidst the gathering darkness.
