Li Hao, a graduate student in the Department of Modern History, accidentally traveled through a thousand years and became Li Chengqian, the eldest son of Emperor Taizong of the Tang Dynasty. Living in the whirlpool of power in the prosperous age of Zhenguan, while using modern thinking to solve the dilemma of the East Palace, he witnessed the wheels of historical destiny rolling in - Wei Zheng's harshness, Li Tai's sharpness, and Hou Junji's ambition were intertwined into an inescapable web. When the brothers' feud turned into a bloody game, and when his father's expectations turned into heavy shackles, Li Chengqian vowed to rewrite the tragic ending of the "deposed prince". However, under the undercurrent of power and intrigue, he had to fight against the torrent of history with his flesh and blood, and in the glow of the prosperous Tang Dynasty, he wrote a lamentable legendary epic of "If the Prince Lives Not to Die".
