Chen Yan, a theoretical physicist from the 23rd century, transmigrates to the Qin dynasty after an accident during a string theory experiment, his consciousness attached to the body of a down-and-out fangshi. Relying on a future scientific database, he uses basic physics to improve Qin-era production and military affairs, helping the Qin dynasty break free of history’s inertia and unify the world. He then drives the evolution of civilization, from the age of steam to interstellar travel, steering a course through conflicts among mechanical, biological, and symbiotic factions. In the end, he leads humanity to make contact with extraterrestrial civilizations, break through dimensional limits, and advance toward ultimate civilization.
