Qing Transmigration: Winning Favor Through Dreams

[Alternate Universe] Zhang Jinxing was inexplicably chosen to join a massive group of people who transmigrated. With no other choice, she had to fulfill the original host's wish before she could return home. But she never imagined the emperor would be so easy to win over. While she was congratulating herself, Kangxi was baring his fangs where she couldn't see.

Ever since Kangxi followed that absentminded, adorable young woman to a strange yet fascinating place, he had been deeply intrigued by her. At first, it was just curiosity. Before long, she occupied his every thought, and he was more than happy to send his harem away for her.

P.S. The heroine has plenty of golden fingers, but none of them are much use. At first, the author planned to have Kangxi discover the merits of modern institutions and, together with the heroine, gradually lead the Qing Dynasty to world domination and transform the feudal system.
