Xue Lin, an orphan from a poor family, failed in the imperial examination and was humiliated by a dandy. He accidentally obtained the notes of the former No. 1 Scholar and awakened the power of photographic memory and strategic planning. After one year of repeated studies, he reached the top of the list. After entering the court, he relied on his IQ to plan and accurately take sides in the party struggle, rectify the government, benefit the people's livelihood, and slap the face of those who mocked in the past. He had no background to rely on, and eventually became a famous minister. However, he refused to marry and gave up power. He retired to the south of the Yangtze River and wrote books and legends, leaving an eternal legend of the counterattack of a poor family.
