On the day of her wedding, Shen Shuyan, the direct daughter of the Grand Tutor, was abandoned by her groom Xiao Huai, his childhood sweetheart Liu Yunwei, and became the laughing stock of the capital. Thanks to her father's support, she domineeringly broke off the engagement. Unwilling to be humiliated, she set up a trap to fight back. She reversed public opinion through the treasure reward event, and was even unexpectedly granted the title of Lord of Anhe Township by the emperor. Later, it was discovered that Liu Yunwei was the orphaned daughter of the salt transport envoy of the former dynasty. She used Xiao Huai to take revenge, and was also involved in the corruption case of the Minister of War. Shen Shuyan teamed up with his father to find out the culprit, and finally made An and the princess the princess based on his merits, and lived his own glorious life.
