Lin Yu felt a flash of white light before his eyes, and when he opened his eyes again, it was the countryside in 1899. The unfamiliar adobe house and the crowing of chickens and dogs outside the window put this 21st century medical student in a trance. When he went out, he bumped into Xiu'er, a pretty girl from the village. Xiu'er saw that he was dressed strangely, and her eyes were full of curiosity and vigilance. Lin Yu hurriedly explained that he had lost his memory, and then dispelled Xiu'er's doubts.
