Nüdi? Wo Zhi He Niangzi Tan Lian’ai

Gu Ning, a love novice and galgame loser, travels to a supposedly hardcore court intrigue game called "Above the Empress," becoming the perverted commander of the Jinwu Guard. She knows she must protect Empress Jiang Yuelin and conquer the lands to unify humanity. Despite possessing a system and knowledge beyond her time, she's still terrified because this wacky intrigue game actually has options, and whenever she chooses, she always picks the wrong one!
