After I Transmigrated, the System Reincarnated, and I Became Human

Cui Shijiu, a modern office workaholic who stayed up late working herself to death, transmigrates into the body of a concubine’s daughter in ancient times. Even more astonishing, the original owner becomes her System. A voice from beyond the heavens declares that, as the System, the original owner must help Cui Shijiu overcome eighty-one trials. Otherwise, her body and soul will be obliterated. Cui Shijiu must also help the original owner fulfill her last wish, or she’ll never be reincarnated... There’s no choice. What can she do? Time to hit the books!
