Murong Xue, a female college student, disguised herself as the legitimate daughter of the general's palace. When she opened her eyes, she fainted in the arms of Li Taibai, the owner of a hexagram stall. She was also bound to a tarot divination system - she was rewarded for drawing cards, but the mission always forced her to get close to the poisonous hexagram stall owner. She uses tarot, while he calculates plum blossoms. The two kinds of divination go from trying to undermine each other to joining forces to break the situation. Finally, they discover that he is actually the third prince of the current dynasty, and the real mission of the system is to let her stay and be his queen.
