In the fourth year of Yongzheng's reign, a young man wearing a sweatshirt appeared out of thin air outside the Yangxin Hall. He has no fame, no household registration, no backer, only a mind brought from three hundred years later. Starting from planting strawberries and baking cakes, he became Yongzheng's science teacher, foreign affairs adviser, and political confidant. In thirty years, he rose from a sixth-grade candidate to a first-grade bachelor, experienced imprisonment, and also raised the Golden Flag of Taizu. This is the legend of an ordinary person who "ruled the world without killing people" in the era of imperial power. It is also the story of two lonely souls who know each other and cherish each other across time and space.
