Chen Yan, a top modern student, transmigrates to the early Qin dynasty after an experimental accident. The realm has only just been unified, and everything is waiting to be rebuilt, yet currents of unrest run beneath the surface as remnants of the Six States linger and technological civilization remains primitive. Fortunately, the “Civilization Technology Library” he carries with him arrives too: a vast database containing everything from basic engineering to the core technologies of an interstellar civilization.
With the First Emperor's ambition and suspicion to contend with, as well as primitive productivity and a rigid social hierarchy, Chen Yan uses the library as his foundation. Starting with improved farming techniques and the production of cement, he gradually sows the seeds of modern technology in this ancient land. He establishes schools to spread knowledge and workshops to develop machines. Amid clashes with the age and struggles at court, he sets the Great Qin's iron cavalry on the rails of the steam age, replacing the sharp edge of Qin crossbows with the fire of guns and cannons.
From standardizing weights and measures to building a global communications network, from pacifying the realm to sailing among the stars, Chen Yan leads this ancient empire beyond the bonds of gravity. It opens new frontiers in the vast universe, clashes with alien civilizations, and ultimately uncovers the deepest secrets of technology, leading the Great Qin and all of Huaxia civilization on a technological ascension that will shake the galaxy.
