Electric Datang: Dimensionality Reduction Attack

Electrical engineer Zhao Heng opened his eyes and traveled back to the Zhenguan period. There is no system, no golden fingers, just a brain of modern engineering knowledge. Others traveled through time to become princes or generals, but he almost lost his life when a knife was put to his neck at the beginning. In order to survive, he used bamboo tubes to make float valves to help mines solve drainage problems; he used copper sheets and fur to create static electricity, allowing people in the Tang Dynasty to see "electricity" for the first time; he used wood and gears to create primitive logic controls to automate the workshop. The mine head was convinced, the county magistrate was invited, and the Ministry of Industry came. From a homeless refugee to the number one electrical engineer in the Tang Dynasty - he just wants to prove one thing: knowledge is the hardest cheat.
