The Crown Prince's Notes (Female-to-Male Transmigration)

After spending over twenty years as a woman, Rong Yi wakes up one morning to find herself a prince with all the right parts. And not just any prince: she's the crown prince, whose mother is dead and whose maternal family has been exiled. To survive, Rong Yibai acts stupid and plays dumb during the day, then studies hard at night. All she wants is for the emperor to spare her life, in memory of her deceased birth mother... Who could have guessed that, while pretending, Rong Yi would not only save her own life, but also secure the throne? Reading guide: There is a female lead, and more than one! I want three wives and four concubines! Enough to make one mahjong table and one Dou Dizhu table. Theme: Everyone who works hard to live is wonderful.
