Su Wanqing, a master surgeon, transmigrates into the novel she was reading, a period romance about household intrigue, as a disposable legitimate daughter.
The original owner was infatuated with her hypocritical elder brother, was tricked into marrying a playboy prince, and died miserably after the wedding.
Su Wanqing tears up the script and sets her sights on Xiao Jue, the Prince of Jing who dies young in the book:
A sickly war god, with military power in his hands and no interest in women. The perfect backer.
She plays the part of a sweet, obedient girl and takes meticulous care of him. At last, she marries into the Prince of Jing’s household.
She plans to live quietly as a wealthy widow, but then she discovers:
The sickly war god, who was rumored not to live past thirty,
is getting stronger and healthier, and the look in his eyes grows more intense by the day.
Later, on the night of the palace coup, he cuts down the rebels with a single stroke of his sword, then kneels before her on one knee:
“I offer you the world as my bride price. Will you be my one and only empress?”
Su Wanqing finally understands:
She did not transmigrate into a household-intrigue novel, but into the story of a war god raising his beloved to the throne.
