Revenge of the Moon Princess (after time travel)

A girl from the 21st century travels back in time. Hundreds of years to be exact. Possessing a legitimate daughter of the general Qin Haoran\'s residence—a war general who was greatly admired by the emperor of that era. As well as loved by his people.

Since childhood, despite being the legitimate daughter of a great general, Qin Lingyu—the name of the Princess—was always treated badly by her two sisters and also the first concubine.

Gossip has it that Qin Liangyu attempted suicide because her arranged marriage with the fourth prince Ling Junjie, had been cancelled. So, what is the story of Qin Liangyu—with the soul of a girl from the 21st century named Bai Liangyu? Can Bai Liangyu return to the future?
