(Medical skills + space + slap in the face + palace fight and house fight)
Lu Qi, a hidden medical genius, accidentally time-traveled into the body of a concubine of the Hou family. At the beginning, he was beaten up by his sister and thrown into a wolf's den. By chance, he was rescued by the crown prince Bei Chenyu, but she almost kicked his life.
Afterwards, Lu Qi returned to the Hou Mansion and was married to the Prince's Mansion on her behalf before seeking revenge.
On their wedding night, Lu Qi planned to run away, but was caught by Beichen Yu.
"A substitute marriage is death, and running away from marriage is death. Which one do you want to choose?"
"I think I can survive."
