Yin Bai, a girl who died unexpectedly but was full of nostalgia for the real world, decided to use her reincarnation as the price to sign a contract with the space-time adjuster in order to return to the modern world. As the No. 193 Space-time adjuster, she entered the chaotic historical time and space (abnormal Qing Dynasty) and corrected the chaotic history. When he woke up, he found that his soul had penetrated into the body of a Han girl, Lu Yizhi. The girl who was supposed to have died of cholera was resurrected because of Yin Bai's intervention, but her resurrection did not attract the slightest attention from others. In a strange time and space, can the young girl Yizhi, whose parents have died and have a low status, complete the task assigned to her by the space-time regulator? Can she return to modern times as she wishes? Please pay attention to my trial work "Cheng Qing Tian Xia".
