A car accident allows the heroine to be reborn in another world and become Qin Xiaoyao, the daughter of the current general. She is smart and brave, and can be a heroic female general on the battlefield. She could also be the lovely and smart Princess Xiaoyao, she could be a handsome young man walking through the city in men's clothes, or she could be a lady wearing a fairy dress in the palace. A love that travels through time and space, a plot of love and hate, laughter, tears, sadness, love and hatred. It is love that makes us meet and know each other, and it is also love that makes us abandon each other. When we first met, I was young and ignorant. The mysterious surprise when we meet again, knowing each other and falling in love. Just one word can make you look back with a smile, and just one sentence can change your mind with tenderness. The sinister and decisive prince, the dedicated and lonely assassin, and the simple and upright prince. Faced with so many infatuated men, how do you choose? Do you choose because of love or because you are moved? Breaking through the iron horse, taking over the country, love, hate, love and hatred, what is right and wrong? After loving and hating, what will our future be like? In a cold and bloody era, we live for love and die for love. If only it were just like when we first met, chatting and laughing, drinking and singing. Another example is the ending, "I will have no regrets if I die in your arms, my king."
