Lin Wan, a history student, transforms into a short-lived cannon fodder in an ancient sadistic novel. Because he looks exactly like Prince Xiao Jingyuan's Bai Yueguang, he is involved in the whirlpool of the heir apparent from the beginning. In order to save her life, she relied on modern knowledge to help the prince see through the trap of fake military books, but she accidentally got involved in the old case of the Zhenguo Duke's family extermination five years ago. The two went from being allies to working together to investigate the case, uncovering the fake White Moonlight scam in Jiangnan, regaining the secret files of the Western Region, and finally vindicating the old case and eradicating the remaining forces. Lin Wan not only changed the fate of cannon fodder, but also developed feelings for the prince, moving from passive avoidance to a bright future alongside him.
