Fu Xizhou went to the bitter cold border to protect her, and eventually died in battle. For the next thousand years, Jiang Xiaoyue lived incognito and traveled to many countries, enduring the pain of eternal loneliness and disguised identity. She met Wen Jingci and Lu Yaochuan in different eras, who had similar souls to Fu Xizhou, until she met Lin Yanzhi. In the end, at the special exhibition of northwest cultural relics, the armor and black hair carrying the past of the two people made them recognize each other across reincarnation, and they finally stayed together after thousands of years of watching.
