Yu Tangren, a lonely minister of the former dynasty, was personally thrown into death row by the enemy monarch Ji Jinchen. Before execution, his dragon robe was stained with blood, but when his soul was torn apart, he traveled back to his youth. He seized the opportunity, worked step by step, and regained power in the name of revenge. However, on the day he ascended the throne, he found that the tyrant Ji Jinchen, who had slaughtered all his old ministers, was kneeling outside the palace with his broken body, holding in his hand the half piece of jade he had left behind. It turned out that the disaster that destroyed the family was never the result of the emperor's order, but someone tampered with the imperial edict. Now that the country has changed hands, all the old officials regret that he is not dead, but Ji Jinchen is the only one who remembers that he should have been alive.
