I am looking for the novel in which the og villainess was cruel and sent ml to be s******* harrased by old official that came to visit her (horrible) father ...the fl transmigrates into villainess body and saves the ml by saying that she has important info about the emperor(that he is about to die) saying it was some assassin who told her to tell her father ....they believe her and leave the children alone ml is now saved and serves her as a servant. Some points i might remember are 1. they find some hidden treasure, which was some how found by her father and the fl says that she was going to tell him..thus saving themselve 2. she removes a piece of flesh from her body to show her father that she has cut ml's tongue. 3. i guess ml was prince who was sold off as a slave and og villainess happened to buy him 4. along with him she gains another child (i guess raised by wolves or something like that) Yeah so this concludes what i know about it.
