Shadows of Yesterday: Frontier Zero

When the city's infrastructure began to "forget" time, and when a person could disappear without a trace in the 0.62-Second monitoring gap, time engineer Lu Heng discovered that the root of it all pointed to a secret experiment that he thought had ended long ago - "Zero." It does not lead to the end of the universe, but to a Sichuan "just like yesterday". There, his lover Su Lan, who disappeared in the accident two years ago, is still alive, and a devastating city-level disaster is about to come "over there" on September 3. In order to prevent the tragedy, Lu Heng must personally cut off his only way to return to the original universe and save a familiar "yesterday" that does not belong to him from the disaster. But when he returned to his own world, he found that the file had not been rewritten—the people he loved were still in the "world where the tragedy occurred." This is a hard-core science fiction story about salvation and cost, observation and intervention. It has no stars or sea, but the most profound fears about "existence" and "loss" are buried in the tiny error of the city clock. When two "real" worlds exist at the same time, and when your lover has another version, how should you define "home" and how should you face "irreversible" choices?
