Under the treacherous situation of Wushan Kingdom, Ruan Dongsheng, who was born with a frail body, was trapped in a deep house. The fragrance of medicine and his weak body became the shackles of his life. By a strange chance, he actually exchanged bodies with Lin Wan'er, the general's daughter. One is a sickly young man with no strength to tie a chicken, and the other is a heroine with strong martial arts skills. Completely different life trajectories intersect at this moment.
When Ruan Dongsheng held the long sword in his hand, he felt his blood boiling on the battlefield; when Lin Wan'er faced the account books and poems, trying to clear away the fog in the deep house. The two people with misplaced identities not only have to adapt to each other's lives, but also get involved in undercurrents in the court and disputes in the world. An adventure of body and soul begins. Can they find their own way back under the twists of fate?
