I have watched "Red Dust" by Li Rulin, a Taiwanese opera singer, and I like many sisters. I have been deeply involved in it and couldn't extricate myself, so I wrote this article. This is a short story. Because the time travel only lasts one day, it is not long, so It writes about the scene when Li Guang went to fight against the Red-haired Kingdom, mistaking Li Guang for Sister Lin, all kinds of ambiguous actions, words, and all kinds of interesting and tender things with Yun Biren, Zhang Gu and Chu Yun. At the same time, it also witnessed the love between Li Guang and Chu Yun!
