I'm Working in Daqin

In 238 BC, Yingzheng was crowned with a crown and sword, and he was about to take office. Zhao Kai died suddenly and worked overtime, and when he opened his eyes again, he became Zhao Gao, a small official in the hidden palace - the eternal infamy of "referring to a deer as a horse" hung above his head. At this moment, he only cared about how to sort out the pile of rotten bamboo slips in the archives. Without a system and no knowledge of history, his only weapon is the brain of a modern engineer: discover problems, iterate through trial and error, and implement the plan. From color coding to papermaking, from lost wax casting to steel smelting, he started a silent technological revolution in the most fringe corner of the empire. "This whole job, I'm serious about it."
