Shen Zhaoning, who traveled through time and became a princess of the subjugated Southern Chu, was bound to a "history correction system" - as long as she sacrificed a piece of memory, she could exchange for enemy intelligence and fortune. She used her memory to win battles time and time again, fighting her way out of the brink of national subjugation. But she didn't know that every memory she had forgotten was silently sacrificed and treasured in her body by Gu Qinghan, the national master. He endured the pain of memory tearing for her thirteen times, just so that she would not remember that someone had blocked arrows for her during the war. When Pei Yuanlang's army approaches the border, the system pops up the ultimate option: sacrifice all the memories of "him" in exchange for the country's permanent stability - otherwise the country will be destroyed and people will be destroyed. And she just realized that she couldn't even remember Gu Qinghan's name...
