When it comes to books, I prefer the eldest heroine. The heroine is not a good actress!
Nangong Yue is a king with a different surname in the original text. In the later period, he overthrew the dynasty and ascended the throne because he wanted the people to suffer under the tyranny of the original monarch.
In the original text, Chu Qingyou was a concubine brought into the palace by her cousin. She was a concubine in name only. Later, because her cousin had an accidental miscarriage during a fight in the house and her roots were damaged, she gave birth to a son through her belly. Later, she left the mother to keep the son. In the end, the princess's cousin threw her into a mass grave with a grass type on the grounds that she had the epidemic.
She is the princess's concubine, and now that she has passed through, there is nothing wrong with her cousin.
