Hang Zhao, a talented scholar in modern water conservancy engineering, accidentally traveled back to the reign of Renzong in the Northern Song Dynasty. At that time, the water transportation was blocked and the transportation of grain and grass was delayed, and the court was helpless. With no worries, he relied on his advanced engineering knowledge to start from the renovation of the Bian Canal, step by step to build a supporting infrastructure system, clear the north-south water transport network, and break the original transshipment dilemma. There was no female protagonist in the whole process, and he devoted himself to river engineering affairs.
