When they arrived in Dan Plains, Dan Plains' Master, Shangguan Yan, was angry at Yin Qi, so she made things difficult for him and evaluated him for expected husband's behavior. Yin Qi passed the tests and met Shangguan Jing. There, he understood that the lady was supposed to live a free life, but to maintain the hundred-year alliance between Dan and Xin Plains, she gave up that life and chose to live in a palace. As such, he wanted to make her life happier. On the other hand, although the relationship between Li Wei and Yin Zheng is getting better, Li Wei has not yet noticed her own intentions, and accidentally said that she has no feelings toward Yin Zheng. Shangguan Yan didn't want her sister to suffer again, so, to maintain the alliance, she proposed to marry Yin Zheng. (Source: Viu)
