Is the Leader of the Secret Guard Camp a Substitute for the Princess?

When the Duke of Zhenguo took back the eldest daughter of his original wife, everyone thought that the eldest daughter who had been raised in his hometown village since childhood must be cowardly and meek, like a white lotus swaying gently in the wind. She was temporarily brought back from the countryside by the Duke of Zhen to deal with the engagement with the seventh prince. Her biological mother died young, her stepmother was unkind, her father was indifferent, and her future fiancé was very unhappy with the actions of the Duke of Zhen. However, On her first day back at home, she made things difficult for her step-wife during the day and saw a ghost in her room at night. She was so frightened that she was bedridden. In the third month after returning home, His Majesty Liuli Yan arrived. Assassins rushed out. The eldest lady kicked up the table to block the cold arrows that were rushing towards the emperor, and shouted: "Are you all useless if the Royal Forest Army doesn't protect you?" Six months after returning home, His Majesty was poisoned and fell into coma, and the Crown Prince plotted rebellion. The seventh prince gathered his confidants in the main hall to discuss important matters with the ministers of the Manchu Dynasty. The eldest lady came with a sword and her eyes were cold: "Xuanji, the leader of the secret guard camp, is here to see you." The light armor was stained with blood, and the three-foot green front flashed with cold light. The seventh prince and his confidant, the eldest young master of the Zhenguo Palace, slowly opened their mouths. Master Zheng, the leader of the Royal Forest Army, thought to himself: My wife is so handsome! All the secret guard camp leaders in the past were lunatics, but Gu Luoda was a lunatic who cared about the people. Ps: The male protagonist is not the seventh prince! The substitute marriage failed! The male protagonist is the leader of the Royal Forest Army, and the heroine is a cool story. There will be no plot where the strong woman and the strong man are stronger, and the heroine will look for her husband when something happens (I am disgusted)! ! !

Why should we stick to the four directions?
