Great Xia is in decline, ranked last among the Six Nations. Victor, second son of the Frontier Marquis, is the capital’s laughingstock. After his elder brother’s death, his parents maintain a ten-year deception: fake masters train him, and opponents are paid to lose, making him believe he is invincible. The world sees a useless fraud—yet Victor is a true genius pretending to be a fool. Following his brother’s guidance, he secretly enters a hidden martial sanctuary and masters supreme arts. To protect his ill mother, he keeps playing the act, hiding his true power from all.
