[Imperial Examinations + Political Intrigue + Military Family + Overwhelming Intelligence] Gu Beichuan transmigrates as the only heir of the Duke of Zhenguo's household. His grandfather is a god of war, his father a fierce general, and for eight generations, every man in the family has been nothing but a brawny brute who knows how to chop people up! The emperor is sharpening his knives, ready to slaughter the Gu family like pigs. Gu Beichuan eyes the heavy weapons in his hands. “This is a high-level game. Time to try a different strategy.” Soon, the entire court is horrified to discover that the useless, spoiled son of a military family has changed! While others rely on rote memorization to pass the imperial exams, he uses the logic of policy essays to write brilliant proposals that astound the examiners! While others scheme and plot to gain power, he uses game theory to set traps and ruin corrupt officials! The Grand Tutor: “One essay by Gu Beichuan is worth a hundred thousand troops!” The emperor: “My dear subject, take the post of Grand Secretary. I beg you, just don't let your father bring his troops back!” Gu Beichuan spreads his hands. “I only wanted to pass the lowest imperial exam and save my own skin. Who knew I'd accidentally make all of you look like amateurs?”
