Transmigrated Into Your Arms

Yun Jinchu was a contract killer in the twenty second century and died on a job. She woke in a body in the ancient past, drugged, with a man lying underneath her who had been given the same thing. She pulled the clothes off him and found out what he had been hiding for years. The heir to the Zhen'nan princedom was supposed to be so sickly he wheezed after a few steps. He was not ill at all. He was also ruthless enough to wipe out a whole family when it suited him. After that the two of them were tangled together, and the factions at court pulled them into their schemes. Yun Jinchu wanted to survive it. She fought her way through, hit back at anyone who came for her, and picked fights the moment a conversation went wrong. Once she worked out that the heir was the one everything turned on, she went to him to sue for peace. He had been looking for a chance to kill her. He took hold of her hand and said, "I'll marry you."
