The young man's scorching sun and high spirits gave her stability and allowed her a moment of tenderness. However, the court overturned, He was wronged, and his mother and concubine gave him life in exchange for his life. He fell from the clouds into the mire and was imprisoned for half his life. She gave up stability and stayed with loneliness, accompanying him through the loneliness and coldness. In order to take revenge and seize power, he agreed to the princess's marriage contract. On the wedding day, he rebelled and the capital was stained with blood. She traveled with the army, practiced medicine in plain clothes, and watched over him year after year, but she watched him be devoured by lust for power and become a cold-blooded emperor. With her original intention destroyed and her warmth gone, Lin Yuenong left decisively and hid in the mountains. After he was found, he was imprisoned in a paranoid manner, but was plotted by a villain, causing her to be poisoned by a strange poison, and her life was hanging by a thread. Looking into her dead eyes, He Yanheng finally let go. When the mountains and rivers stabilized, he lost his pride as an emperor and chased his wife thousands of miles away, hoping only for the moonlight to return, but the lost youth and love were no longer what they were before.
