Chen Luonian, a modern civil engineer, traveled to a fantasy world that was flooded. The people here regard the flood as the anger of the river god, so they only offer sacrifices and pray, and wait for death. Chen Luonian discovered that the so-called "divine wrath" was just the inevitable result of hydrological laws and backward water conservancy projects. He used scientific knowledge as a weapon to challenge deep-rooted theocratic beliefs. Build dams, build high walls, dig rivers, build reservoirs... When modern engineering miracles appeared one after another in this ancient fantasy world, the so-called "River God" finally couldn't sit still. This is a story about a mortal who took "infrastructure" as his guide, changed his fate against the will of heaven, and finally moved the gods.
