Build a Steam Engine at the Start

Shen Feng traveled to a 15-year-old high school freshman in a parallel world. He didn't expect that this parallel world would be so similar to the seventeenth century, and that scientists all over the world were still studying it. Who I am? Who am I? Where do I come from? Where do I want to go? He starts by building a steam engine. So, cars, ships, planes... Came one after another!

Countless world overlords, weeping and lamenting, wanted to ask him to give him a steam engine. Because the steam engine can dominate the boundless oceans and fly over...
