Xu Miaowan, a quick transmigrator, parachutes into the Marquis's mansion’s plot of disaster. At the start, she knocks out a drugging man with a bronze censer and, in a twist, turns her stepmother and half-sister's scheme against herself into a means of self-proof. She meets Xie Jinghong, a fated son inherently prone to social downfall, and together they turn famous moments like him climbing over walls and tearing his pants, a polo accident, and falling in the court into brilliant displays of intelligence and courage. The two join forces to overturn the Eastern Palace’s conspiracy and kill the foreign demon, only to discover that the demon was merely a pawn, and an even more dangerous opponent has set an inescapable trap in the second world.
