Lin Yan, a graduate student in the Department of Modern History, died suddenly while staying up late to write a thesis on Li Yu. When he opened his eyes, he transformed into Li Yu, the late emperor of the Southern Tang Dynasty who had just succeeded to the throne. Fully aware of the fate of subjugation that "the motherland cannot bear to look back at the bright moon", he carried the memory of historical books and the historical notes on his mobile phone, and shouldered the responsibilities of an emperor with the bones of a scholar - reforming bad government, reorganizing the armament, improving people's livelihood, and trying to reverse the historical trend.
In the court, he competed with the intertwined aristocratic family, struggling between the shackles of the ancestral system and the real crisis; in the palace, he had a deep love with the Empress Ehuang of the Great Zhou Dynasty, and they went through thick and thin together. He expressed his feelings in poems, writing about the sorrow of "the north wind blows in the old garden, and the chill penetrates the dragon garden", and also sang the deep feeling of "I am willing to win the person of my heart, and watch the moon in the south of the Yangtze River together".
But the gap between the times is difficult to bridge, and the iron hooves of the Northern Song Dynasty are unstoppable. He devoted his life's efforts, but ultimately failed to shake the direction of history. The city of Jinling was destroyed, the country changed hands, and he became a prisoner. He watched helplessly as his beloved Xiao Zhou was humiliated by Zhao Kuangyin. He was left with the eternal lamentation of "How much sorrow can you have?" And his lifelong struggle confirmed the tragedy and regret of "the irreversible flow of history".
