Chen Shimei, who had betrayed his wife and abandoned his son in his previous life and suffered a ruined reputation, repented before being beheaded, but all that was left was the regret of blood splattering on a dog's head. Once he was reborn, he returned to the Golden Hall where he was the top scorer in high school - this was the starting point of his twisted destiny. In this life, he swore to stick to his heart, refused the emperor's marriage offer, refused to marry a dragon and a phoenix, and won the support of the Eighth Prince, Bao Zheng, and the Prime Minister with his righteousness. Although he angered Long Yan and sent the county magistrate, he returned home with modern thinking, treated Qin Xianglian and her children well, respected her parents, used forensic knowledge and logical reasoning to solve local strange cases, and gained a firm foothold step by step.
He took over the Five Rats on Xiankong Island as his arm, unearthed the hidden Song Dynasty generals and trained elite troops, and even had the opportunity to learn peerless martial arts. After entering the capital, he joined forces with Bao Zheng to investigate classic and mysterious cases such as "The Black Pen", "Blood Handprint" and "Civet Cat for the Crown Prince". From being released as a county magistrate to having power over the country, from being alone to marrying a princess and taking charge of the military and political affairs, Chen Shimei used modern wisdom to innovate the military system and people's livelihood of the Song Dynasty, led a strong army to intimidate the Liao, Xia, and Jin Dynasties, and finally transformed the "weak Song" into a "strong Song". It not only wiped away the stigma of the previous life, but also became a legend of a famous ZTE official.
