Faced with the frame-up of Concubine Liu and the oppression of Xiao Che, the two of them insisted on justice, helped Shen Yanzhi win the imperial election in autumn, and also revealed the truth about Brother Su's old case. In the end, Xiao Che surrendered and Su Wanwan regained her freedom. She and Shen Yanzhi went to the south of the Yangtze River together, making their study their home, and continued to write the fate of "carrying together in a boat".
