Record of Technological Change: the Epic of Return to Ruins

Qin Yu, a modern engineer, accidentally traveled to an ancient feudal dynasty where technology had stagnated for eight hundred years. The people here adhere to the decadent creed of "exotic skills and ingenuity are not used by gentlemen". They rely on earth furnaces for iron smelting and wooden plows for farming. Starting from remodeling a plowshare and recasting a blast furnace, Qin Yu established the "Tiangongfang" with a crushing force, smashing the commercial blockade and political encirclement and suppression of the conservative Zhou family with one blow. However, when the fire of the Industrial Revolution really ignited in this ancient land, he discovered that the eternal white disk in the "double sun" above the sky had a strange gaze. This is not only a dimensionality reduction attack by modern technology on ancient times, but also a civilization trial involving the dimension of "return to ruins" and spanning five major eras. Science is the sword and dimension is the sheath. Eight thousand years of feudal shackles are destined to be reborn in this fire.
