It's Hard to Hold on to the Beautiful Clothes

As everyone knows, Wei Heng, the legitimate son of Duke Zhenguo, is the most dazzling young man in the capital, with both civil and military skills, and is the sharpest sword for the third prince on his way to the throne; while Princess Mingyue Li Zhaohua is a weak beauty who was pampered in the palace. She is proficient in music, chess, calligraphy and painting, but is an insignificant embellishment of the royal family. They were once childhood sweethearts, but due to their different positions, they became tit-for-tat rivals in the court. At the palace banquet, she slipped and fell into the water, and he rescued her in public, but there was only ridicule in his eyes; in the game of power and chess, he worked step by step for the honor and disgrace of the family, and she used her illness as a cover to transform into a military adviser of the former dynasty code-named "Jin Shu", secretly weaving an intelligence network and stirring up trouble in the capital. When the third prince was defeated and the Duke's palace was in turmoil, Wei Heng broke into the princess's bedroom late at night, only to find the room full of people in solemn silence - the legendary man behind the scenes was bowing his head to her respectfully. The friendship between childhood sweethearts has been tempered in the whirlpool of power and intrigue; the game of two-sided life has deep feelings hidden in the light of swords. From testing each other to breaking the situation side by side, from a bloody feud to joining hands to rule the country, they used the world as a chessboard and people's hearts as pawns, and finally stood at the top of power, guarding thousands of miles of rivers and mountains together. Is this chess game mixed with calculation and sincerity a matter of deep-rooted love, or is it hard to trust the book?
