Tong Xin transmigrates into a book, landing in an old-fashioned novel about a pheasant being switched with a phoenix.
And she is neither the pheasant nor the phoenix in the story. She's their mother.
Tong Xin doesn't care about any of that. One of them is bound to be the heroine, and whoever it is will take her along on the road to the top.
Wait, the heroine is a fallen phoenix?
No problem. She'll just raise her well.
What? The heroine is reborn and knows Tong Xin switched their identities? And Tong Xin has been abusing her all along?
Tong Xin: "..."
I'm freaking out right now.
Luckily, the man who was supposed to die far from home has returned, and even secured an imperial decree for her, granting her a noble title.
