I’ll Conquer the World for You, If You’ll Guard the Rest of My Life

Xiao Huixin, a modern forensic psychology expert, transmigrates into the body of a lowborn daughter of a marquis's household who is constantly bullied. In a moment of danger, she is rescued by the cold-faced Prince Feng Moyan. With her knowledge and strategic skills far beyond her time, she helps him crack one baffling case after another, uncover the truth about his origins and a blood feud, and even invents a devastating weapon called the Thunderclap Bomb in the desperate northern frontier. This helps him seize military authority and win repeated victories, turning the tide of fate. The two return to the capital with their troops, purge corrupt officials, execute traitors, and help the new emperor ascend the throne, finally clearing the name of those wrongly accused in a case that had remained unresolved for twenty years. But just as Feng Moyan stands at the height of his power, he is struck by a deadly poison while saving Xiao Huixin, leaving him on the brink of death. Xiao Huixin resolutely abandons her immense power and leaves her post. Carrying Feng Moyan on her back, she travels across countless mountains and rivers in search of the legendary antidote. At last, she finds it in the Peach Blossom Spring and awakens the man she loves. The two retire from the world together, surrender the empire, and spend the rest of their lives by each other's side, creating a legendary love story: “I planned the world for you, and you kept the rest of my life safe.”
