Li Lin, a modern young man, accidentally traveled to the prosperous age of Kaiyuan and entered the turbulent officialdom as the richest man. Starting from a humble Yuanwailang in the Ministry of Household Affairs, he relied on his insight into historical trends and wisdom beyond the times to make his way step by step in the court where there are dense unspoken rules.
He fought against the torrent of history and used modern thinking to reshape the prosperous age, but he also glimpsed the abyss of human nature at the peak of power. This is a legend about persistence and change, as well as an ideal of family and country that spans thousands of years.
