Everlasting and Prosperous

It is known to all the three kingdoms that the Emperor of Sheng State loved the fifth princess the most and bestowed upon her the title of Princess Changsheng. But I don't know the meaning behind this. The long-lasting prosperity is not the long-lasting prosperity of the princess, but the long-lasting prosperity of the prosperous country. She has known since she was a child that if she wants to live freely in the era of monopoly, she must have the strength to compete with it. She volunteered to become the secret sword of the Sheng Kingdom, became her father's most trusted child, and mastered the royal secret chess. She just doesn't want to be like other royal princesses, enjoying the false reputation of the royal family but dedicating their life's freedom, happiness and even their lives to the rise and fall of the royal family. She wants her destiny to be in her own hands, and she needs the strength and right to compete with her destiny. He is the crown prince of the most powerful country among the Three Kingdoms, and he is a unique genius highly praised by the world. Civil and military skills, wisdom, city government and scheming are all beyond his reach. The two tested each other and fought many times, with both winning and losing. In the battle between the strong and the weak, it turns out that they have become each other's most important people in the pursuit of victory or defeat. The two are equally proud, noble, scheming and resourceful, and their strategies rival those of the city. They were rivals but ended up together. This was a duel and competition between strong men.
