Four years ago, the Changxin Palace was massacred overnight. Only the fourth prince, Fu Shiqing, survived, and was taken back and raised by Gu Chengyan, who rescued him. As the adopted son of Emperor Yuan and his former dead bodyguard, Gu Chengyan was extremely powerful and had killed countless people.
Four years later, while investigating the Changxin Palace murder case, Fu Shiqing met the imperial censor Wen Yun and the Liang Crown Prince Xiao Yu. The two approached him with their own purposes and used him, which eventually led to a break between him and Gu Chengyan.
Intention: Some mistakes can be made up for, and some mistakes must be repaid.
