The Truth System: Escape from Urban Legends

On the screen of Chen Mo's mobile phone, the last message came from his sister Xiaoyu: "Brother, the legend about the typist in the library seems to be true." Three hours later, he fell from the top of the library. Then he woke up - back to 24 hours ago. [Urban legend truth traceback system has been bound] The text on the screen is as cold as code: [Death of bound person detected Rewind: time point confirmed (24 hours before Xiaoyu disappeared)] [Currently active legend: 1] [Mission: Ghost typist in the old library - Investigate the truth about Su Wanqing's "data residue" in 1988] [Time limit: 72 hours] This is not a game. This is a warning. It's looking for a host. It's learning to evolve. The "backtracking system" that Chen Mo obtained may be the only loophole - or it may be a bigger bug. The countdown begins in 72 hours. He wants to find the underlying code of the truth before his sister is "covered" by the legend, and then... Either repair the system or completely format it.
