Before the death of the late emperor, he entrusted the crumbling country and the twelve-year-old young emperor Xiao Jing to his younger brother An Wang Xiao Ting. At that time, Xiao Ting was only eighteen years old. Although he was extremely intelligent, he had been weak since childhood. He was sick and shouldered the heavy responsibility of regent, walking on thin ice in the turbulent court.
He and Shen Yan, the son of General Zhenguo, were close friends and had a deep friendship. Shen Yan has been with him since childhood, knowing his tenacity under the warmth, and understanding the loneliness in his forbearance. His heart has long been secretly promised, and his feelings have long surpassed Youlun, but they can only be hidden deep under the iron-blooded armor. Until Xiao Ting's body completely collapsed and he escaped alone after the new emperor came to power. He disappeared into the smoke and clouds of Beijing, leaving no words to Shen Yan.
After returning, Shen Yan felt as if he had fallen into an ice cave when facing his old mansion in Kongting. Regardless of the general ethics, he confessed his shocking feelings to his family, gave up his prosperous future, traveled thousands of miles of mountains and rivers, and searched like a madman for the sickly figure for five years.
Emperor Tian failed, and a sudden rain in the south of the Yangtze River forced the two of them into the same remote cave in a deserted mountain. In the flickering firelight, five years of longing and five years of illness suddenly confronted each other. Shen Yan saw that his once glorious prince was now so thin and breathless. The old servant beside him cried out that the prince had been ill for a long time and had reached the point where the oil in the lamp was exhausted. Shen Yan was heartbroken and almost begged, and finally persuaded Xiao Ting to return to the capital, hoping to devote the rest of his life to protecting him.
However, the tree wants to be still but the wind does not stop. The young emperor Xiao Jing is running the country poorly, the government is in chaos, and border wars are rising again. Seeing that the mountains and rivers he has guarded all his life are about to collapse, how can Xiao Ting sleep in peace?
