The Princess Who Helped Her Brother Take the Throne

Qin Ye, reborn in the Great Qian Dynasty twenty years ago, gets entangled with the sixth prince Chu Lan, who is disguised as a man. A late-arriving strategist system binds them together, erasing them from existence if they fail. Using modern knowledge and system items, Qin Ye helps Chu Lan solve the Wuhuan riddle, win the autumn imperial exam, and quell border unrest, ruthlessly slapping faces of the third prince and the corrupt minister's faction. From mutual suspicion to deep love, Chu Lan's pregnancy reveals Qin Ye's true identity as a woman. Together, they crush the usurpation plot, see Qin Ye ascend to the throne, and build a golden age for the Great Qian Dynasty.
