The Investiture of the Gods throws the world into chaos. The Shang and Zhou dynasties clash, war spreads like wildfire, and demons and immortals rise together. The Great Zhou has just been founded, its foundations still shaky. A modern engineer unexpectedly transmigrates and becomes the regent, the Duke of Zhou. With the cataclysm of the Investiture of the Gods approaching, the remnants of Zhaoge still at large, and the immortals' rivalries spilling into the mortal world, the Great Zhou stands on the brink of ruin. Armed with a modern knowledge base, he casts aside outdated customs and uses technology to break through the chaos of the Investiture: building waterwheels to aid farming, smelting steel to forge divine weapons, crafting firearms to counter demon arts, and creating a calendar to establish order. Though only a mortal, he uses the power of technology to help King Wu unite the realm, resolve the immortals' conflicts, suppress rebellions across the land, and break free of the constraints of the Investiture. He transforms the tottering Great Zhou into an enduring dynasty that lasts eight hundred years. From wise regent to legendary figure of the Investiture, witness how the transmigrated Duke of Zhou wields technology as his blade and strategy as his shield, forging an epic tale of a mortal using science to protect the world amid the chaos of the Investiture.
