Traveling to Another World to Engage in Industry

While others were still trying to increase their knights, Ye Tian had already started a plane plan to take the harem into the sky. This is a backward multi-racial world, with not only humans, but also orcs, elves, dwarves, gnomes... As a time traveler, Ye Tian naturally cannot leave behind any of technology, culture, entertainment, politics, economy, military, food, clothing, housing and transportation.
