In the fifteenth year of the Great Zhou Dynasty, there will be a general examination. As the chief assistant of the cabinet and the examiner of this year, Song Yanxiu has always been known for his selflessness and rock-like heart. He once personally imprisoned his mentor, and also watched his wife die of illness without shedding a single tear. Until he reviewed a paper. The handwriting, clear and elegant, is the familiarity engraved in his bones and blood. It was the handiwork of his late wife, Shen Shuwan, who he had taught personally and watched with his own eyes as she was buried. Absurd. He sneered, it was just a coincidence. But when he saw the examinee named "Jiang Sui", Song Yanxiu could no longer calm down. The scholar was thin and handsome, with half the shadow of his deceased wife between his eyebrows and eyes, and on his ears... He was wearing an emerald earring that was supposed to be buried with his deceased wife. A person who has been dead for ten years, a pair of earrings that should have been buried deep in the ground, and an identical handwriting. Late at night, Song Yanxiu retreated from his entourage and quietly followed the man all the way to the mass grave on the outskirts of Beijing. The moonlight was miserable, and I saw the thin "scholar" kneeling in front of an unknown solitary grave. With trembling hands, he tore off a thin layer of disguise from his neck, revealing his smooth throat. A clear female voice with a weeping sound struck Song Yanxiu's heart word for word: "Mom, don't be afraid, my daughter is going to be successful." "My daughter took the exam for you and won the first prize."
