Lin Xiao, 25 years old, graduated from the Computer Science Department of a prestigious 985 school. He was maliciously expelled for exposing the corruption of department managers. My mother suffers from chronic kidney disease and has heavy medical expenses. He delivers food during the day and works part-time as a coder at night. He lives a difficult life but remains optimistic and humorous. While delivering the last takeout order on a rainy night, he was hit by a truck to save a child who ran a red light. When I woke up, I found myself lying on the streets of Bianjing in the seventh year of Xuanhe in the Northern Song Dynasty (1125), wearing takeout clothes, with a damaged electric car lying next to me. My mobile phone had only 1% battery left and no signal. In troubled times, see how Lin Xiao helps Yue Fei fight against the Jin Dynasty and save the Song Dynasty, and turn the tide.
