Doctor of Military Industry Transforms into Fourteen-Year-Old Xin Qiji

The military doctor traveled through time and became Xin Qiji. But he is not fighting alone. Qingque, the adopted son of Xin Zan, is a paranoid technology geek. He lost three fingers and carved the first rifled cannon with his left hand. Mrs. Su, the daughter of an old craftsman, suffered a severed tendon in her right hand. She calculated ballistics with her left hand and passed down skills with her mouth, becoming the "fire control computer" of the artillery team. Xu Ke, an old foundry, seventy years old. He led the craftsmen to try more than a dozen recipes in the mine, and fired the first blue brick in Liaoyuan City. Three people, combined, only have one and a half good hands. But it was this one and a half hand that created the most terrifying weapon of this era from scratch in the scorched earth of the Southern Song Dynasty. Thirty thousand gold soldiers pressed down on the border, and fifty artillery pieces were aimed at the city wall. Xin Qiji stood at the top of the city, with six prison-breaking cannons behind him and Wanyan Zongfu's cavalry in front of him. "Fire." Eight hundred paces away, the flagpole snapped. This is not only the romance of technical nerds, but also the story of the Han people who lost their backbone for hundreds of years and recast it into iron and fire.
