Rebirth and Working in Ancient Times

Lu Qingqing, who was originally from a wealthy family, fell behind in her family life and devoted herself to making money. However, she suddenly died unexpectedly and was reborn in an imaginary Da'an Dynasty similar to ancient China. The reborn Lu Qingqing was a dying 6-year-old child who was adopted by four pillars. For the sake of her innocence, they decided to temporarily raise her as a girl disguised as a man. For the sake of her adoptive father and her own life, Lu Qingqing decided to use the careerism she had before her sudden death to build the first chaebol in the Da'an Dynasty.
