Sci-fi

Yang Feng somehow transmigrated into a  different world and received a legacy of an ‘ancient high tech’ family,  which does not directly raise his power, but gives him the technology to  build things which are way more advanced than the seemingly medieval  world.
    But to build something you need resources and energy. To receive  resources you need strength. To gain strength you need knowledge. To  gain knowledge you… need strength? or a background? Or maybe a fully  armed army of high tech robots who aren’t afraid of death?
    But is this legacy really for him to keep?
