Mu Han, a good-for-nothing boy, accidentally awakened a damaged ancient core card in the card world dominated by steam machinery.
Other people's cards can only drive steam locomotives and mechanical gauntlets, but his core card can combine the power of machinery and alien beasts. In an era when card masters were everywhere, Mu Han relied on this to sweep the arena, crack the conspiracy of the Steam Empire, and finally reach the top of the card realm, becoming a legend in the steam era.
