I Rely on Beauty to Stabilize the Country

Gu Yuanbai transmigrated into a BL novel as a weak, sickly emperor who barely had any sense of presence in the plot. The novel was a story of the struggle to gain the political power and love between the future regent and the first beauty in the capital, and he was supposed to serve just as a backdrop board.
Gu-wildly ambitious-Yuanbai: Don’t make me laugh.
He was the emperor—why would he let go of his power instead of expanding the national borders and leaving his name in the annals of history?

Xue Yuan, the son of the current supreme general and the future regent, hiding a burning ambition, accompanied his father into the palace for the first time. That day, he looked up, hidden among the crowd of courtiers, and caught a glimpse of the young emperor’s face.

By making people take pity on his frailty?
