The protagonist Zhang Tiezhu traveled through time and became cannon fodder at the bottom of the anti-Qing Dynasty and restored the Ming Dynasty. He used modern chemical knowledge to improve gunpowder, planned to blow up the Qianqing Palace, accidentally killed Kangxi, and overthrew the Qing Dynasty in one fell swoop. With the support of everyone, the "Xin Ming" regime was established, with the reign name "Xin Hongwu".
But overthrowing the old dynasty was only the beginning. Faced with internal and external troubles - the Ming Dynasty's old age constraints, the remnants of the Qing army in various places, Junggar's eyes, and the Western colonists knocking on the door - Tiezhu realized that there was no way out to simply restore the old Ming Dynasty. He must use the knowledge of two hundred years later to push the country to leapfrog into the industrial age.
