Su Wan, a female doctor of modern forensic medicine, accidentally traveled to the Kingdom of Yan during a laboratory accident and became the sickly legitimate daughter of the same name - Su Wan, who was about to marry the crippled prince.
The original owner was poisoned by his stepmother and became frail and sick. On his wedding night, he had to serve Prince Jing Xiao Yan, who had disabled legs and had a violent temper. On the first day of Su Wan's time travel, someone from the palace came to "inspect the goods" - Xiao Yan's lieutenant asked to check whether she was still intact.
Su Wan used a silver needle to prick the deputy general's numb hole on the spot, and said: "Only I can test the person of this princess."
When she saw Xiao Yan sitting in a wheelchair, she saw at a glance that his legs were not disabled at all, but nerve paralysis caused by poisoning - this secret was enough to turn the entire court upside down.
This begins a story in which a princess saves the crippled king, joins forces to reverse the case and take revenge, and gains power over the world.
