On the day of Tao Junran and Yun Hean's wedding, San Yuemei took advantage of her surprise attack and stole the key to the jail. San Yuemei rescued Tao Jun and then the two together rescued Cao Qing. The three were pursued and killed by the dark guards, and San Yuemei died to save the seriously injured Cao Qing. After grief-stricken Cao Qing and Tao Junran buried San Yuemei and Li Yu together, they agreed to return to Biyun County to monitor Yun Jiayu, and Tao Junran searched for Ah Fan alone. Hongyu was wary of Ah Fan because Ah Fan was the daughter of Nan Zheng, and was unwilling to return Nan Zheng's position to her, so she took the initiative to frame her. Lian Qi saw through Hongyu's little tricks and stern words. Tao Junran was chased by Zhuo Jiqing, and Tao Junran would throw an arrow to seriously injure Zhuo Jiqing. Yun Hean cried and begged Yun Jiayu not to hurt Tao Junran and help her find her brother Yunzhi. Yun Jiayu's beloved sister was eager, but she had no choice but to agree. Zhuo Jiqing couldn't love Yun Hean, and secretly hurt herself. Tao Junran finally found the "Mirror of the Sky" at the entrance of Shallow Island and successfully entered.
