Rescue against Time

Xia Xia is a single mother and a senior researcher at the Institute of Physics. For years, she has been working on particle technology that would allow her to travel back in time. One day, when Xia Xia's research was about to succeed, she discovered that her son Doudou had been kidnapped by the mysterious kidnapper Cui Hu. Cui Hu threatened Doudou's life and asked him to hand over his particle technology. In order to save Doudou's life, Xia Xia took the risk of using unfinished particle technology to return an hour and 50 minutes ago. This made things more complicated, and the story behind Cui Hu's story gradually emerged.
