Jiang Xiaorui, a game genius girl, was betrayed and died tragically by her childhood sweetheart ex-boyfriend in her previous life. She once traveled through time and became an abandoned concubine in an ancient cold palace. She thought her life was over, but she didn't expect that time travel came with a golden finger - a game system called "Gongdou OL"! The system treats the harem as a large-scale strategy game. All concubines are turned into NPCs, and various palace fighting methods are turned into game skills. It can even check the favorability and blackening value of the "enemy".
