Ming Dynasty: Teach Zhu Yuanzhang to Supervise the Exam, and I Will Become the Emperor's Teacher?

Li Guanhun, who was a history student in his previous life, traveled to the Hongwu Dynasty, and when he woke up, he was in the Renxu Science Examination where a cheating case was reported. As an examiner, Li Guan was about to face Zhu Yuanzhang's anger and implication before he could fully enjoy the benefits of Ming Dynasty officials, and his head was in danger. Fortunately, he has a system and can get extra help by completing system tasks. If the test questions are leaked, it will be fine if they are repeated! "My father and mother fell into the water at the same time. Who will you save first?" "What chicken doesn't have wings?" The candidates cried when they saw the question. What the hell! Zhu Yuanzhang was overjoyed: "Not bad, not bad, now no one will leak the questions without proctoring." With the help of his brain and system, Li Guan got rid of his guilt, entered the court, and gained the trust of Zhu Biao and Zhu Yuanzhang. He avoided the four major Hongwu cases and became an emperor's master Dangdang? The national power of the Ming Dynasty grew stronger and stronger, and eventually under Li Guan's control, the Ming Dynasty became a country where the sun never sets in the fourteenth century.
