Chen Mo, an engineering student at Tsinghua University, was struck by lightning and returned to Zhenguan three years ago. When he opened his eyes, he saw the Yellow River bursting its banks and the victims wailing. With modern formulas in mind, he actually used Tang Dynasty crucible to burn cement, and built embankments in seven days to shock the government and the public. From a small official working on flood management to serving as a general supervisor, he made steel swords, modified the keels of fortune ships, used "technical examinations" to shake up the monopoly of wealthy families, and used standardized drawings to drive conservative craftsmen crazy. Persian spies, assassinations by nobles, and criticism from the court - but he poured cement into the foundation of the Tang Dynasty, allowing Li Shimin to witness with his own eyes: This industrial counterattack spanning a thousand years will eventually create a prosperous age of roaring steel and gears.
