The play is adapted from Xing Ling's novel "The Emperor's Book". Zi Yuan (played by Dilireba), who is upright and concerned about the people, was originally a founding hero. Due to a sudden change in her family, she was exiled to the people. Unwilling to be strangled by fate, she named herself Ren Anle and decided to do her best to resettle the people who suffered from the war, hoping to create a peaceful home for the people. At the same time, she was investigating the truth, hoping to clear her family's name. In the process of helping the people, she not only gained a certain prestige and praise, but was also appreciated by the prince Han Ye (played by Gong Jun) and became his staff. Subsequently, with the assistance of the resourceful Ren Anle, Han Ye successively broke the imperial examination fraud case and the Jiangnan disaster relief grain embezzlement case. At this time, a war broke out on the border. Ren Anle, who took the people of the world as his own responsibility, decided to follow Han Ye to the expedition, hoping to end the war as soon as possible in exchange for the people's peace and happiness. Facing a situation where the enemy was strong and we were weak, Ren Anle made plans, fought against the enemy despite being ill, won a narrow victory, and the people also welcomed the dawn of peace. In the end, Han Ye helped Ren Anle find out what happened that year and cleared the family of grievances.
