What was the end of fire's visit to princess royal's nirvana?

In the TV series Nirvana in Fire, princess royal in Liyang is a very sad figure. Finally, he personally exposed the crimes committed by her husband, which led to his execution, while his son Xiao left her after learning his life story, leaving princess royal alone in Liyang.

In the play, princess royal of Liyang is a princess, but she is not happy at all. Originally, she and Yu Wenlin, a proton from Southern Chu, were devoted to each other for life. Unexpectedly, this relationship in Liyang was opposed by her mother. Later, after discovering that Li Yang was pregnant, she took a "love affair" for her, which made her lose her virginity in Xie Yu and forced her to marry Xie Yu.

After years of mutual respect with Xie Yu, Li Yang found that Xie Yu was not a good man, and he wanted to frame Princess Huang in the same way. Fortunately, Li Yang told Mei in time that Huang Ni was saved. Later, after discovering that Xie Yu had done many bad things, he personally published Xie Yu's calligraphy, which made the rebellion of the Red Flame Army, which had been wronged for many years, take a new turn.
