Xiao Hanyuan, the eldest son of the Marquis of Jingan, went to war with his father at the age of sixteen. He fought bloody battles for three years and helped the imperial court put down the Xiliang rebellion. He returned triumphantly with scars all over his body and military exploits. He originally thought that what was waiting for him was a family reunion, a loving father and a filial son, but what was waiting for him was a letter of divorce from his aunt - no, it was a letter of death. The aunt's mother claimed that he was not the Marquis's biological son, but a bastard adopted by him, and wanted to depose his eldest son and seize his military power. His father remained silent while his second brother Xiao Hanyu secretly mobilized his troops. Even his most trusted fiancée Shen Qinglan stood by his side. Overnight, loyal ministers become traitors and heroes become outcasts. Xiao Hanyuan was thrown into death row and tortured. He broke his teeth and swallowed humiliation in prison. Fortunately, his former subordinates desperately rescued him, and he escaped and sneaked into the world incognito. Three years later, he used thunderous means to control the world's largest intelligence network, "Guanxing Pavilion", and found out the truth of the year - the so-called "bastard" theory was nothing but a well-planned conspiracy to seize the throne. And the man behind the scenes who had been secretly fueling the flames and trying to kill him was actually the person he had called "mother" for nineteen years. When the truth was revealed and all the blood relatives became enemies, Xiao Hanyuan walked step by step back to the mansion he had built with his own hands, carrying a long knife. This time, he no longer asked anyone to recognize him. He wanted them to know who really didn't deserve the surname Xiao.
