In order to seize military power, the cold-blooded prince Xiao Zhi married the sick and legitimate daughter of Zhenbei Hou, and they agreed that they would only be husband and wife for seven days, each taking what he wanted. On the night of the wedding, assassins attacked, but his new princess, who was about to collapse in the wind, broke the sharp knife with her bare hands and asked with a smile: "Your Highness, is this still going on?" From then on, the seven-day contract was renewed indefinitely. She navigated the harem for him, analyzed the previous dynasty, and pushed him to the supreme position with her astonishing wisdom. When Xiao Zhi finally held the blood-stained Jiangshan in front of her and asked for a real marriage certificate, Lin Wan took out the already yellowed letter of divorce and said: "Your Majesty, it's time to discuss the termination terms of our contract."
